Hadronic vacuum polarization: three-pion channel
Authors: Hoid Bai-Long , Hoferichter Martin , Kubis Bastian 
Published: April 2020

The 3π-channel contribution to hadronic vacuum polarization (HVP) in the anomalous magnetic moment of the muon (g−2)µ is examined based on a dispersive representation of the γ* → 3π amplitude. This decay amplitude is reconstructed from dispersion relations, fulfilling the low-energy theorem of QCD. The global fit function is applied to the data sets of the 3π channel below 1.8 GeV, which constitutes the secondlargest exclusive contribution to HVP and its uncertainty. The dominant ωand φ-peak regions in the e+e− → 3π cross section as well as the non-resonant regions are precisely described to obtain our best estimate. The final result, $ a_\mu ^{3\pi }\left| { \le 1.8\,{\rm{GeV}}\,{\rm{ = }}\,{\rm{46}}{\rm{.2(6)(6)}} \times {\rm{1}}{{\rm{0}}^{ - 10}}} \right. $, reduces the model dependence owing to the fundamental principles of analyticity and unitarity and provides a cross check for the compatibility of the different e+e− → 3π data sets.
A combination of the current analysis and the recent similar treatment of the 2π channel yields a dispersive determination of almost 80% of the entire HVP contribution. Our analysis reaffirms the muon anomaly at 3.4σ level, when the rest of the contributions is taken from the literature.
Dispersion relations for hadronic light-by-light and the muon g − 2

Published: April 2020

The largest uncertainties in the Standard Model calculation of the anomalous magnetic moment of the muon (g−2)µ come from hadronic effects, namely hadronic vacuum polarization (HVP) and hadronic lightby-light (HLbL) contributions. Especially the latter is emerging as a potential roadblock for a more accurate determination of (g−2)µ. The main focus here is on a novel dispersive description of the HLbL tensor, which is based on unitarity, analyticity, crossing symmetry, and gauge invariance. This opens up the possibility of a data-driven determination of the HLbL contribution to (g−2)µ with the aim of reducing model dependence and achieving a reliable error estimate.
Our dispersive approach defines unambiguously the pion-pole and the pion-box contribution to the HLbL tensor. Using Mandelstam double-spectral representation, we have proven that the pion-box contribution coincides exactly with the one-loop scalar-QED amplitude, multiplied by the appropriate pion vector form factors. Using dispersive fits to high-statistics data for the pion vector form factor, we obtain $ \alpha _\mu ^{\pi {\rm{ - box}}} = - 15.9(2) \times {10^{ - 11}} $. A first model-independent calculation of effects of ππ intermediate states that go beyond the scalar-QED pion loop is also presented. We combine our dispersive description of the HLbL tensor with a partial-wave expansion and demonstrate that the known scalar-QED result is recovered after partial-wave resummation. After constructing suitable input for the γ*γ* → ππ helicity partial waves based on a pion-pole left-hand cut (LHC), we find that for the dominant charged-pion contribution this representation is consistent with the two-loop chiral prediction and the COMPASS measurement for the pion polarizability. This allows us to reliably estimate S-wave rescattering effects to the full pion box and leads to $ \alpha _\mu ^{\pi {\rm{ - box}}} + \alpha _{\mu ,J = 0}^{\pi \pi ,\pi {\rm{ - pole}}\,{\rm{LHC}}} = - 24(1) \times {10^{ - 11}} $.

Published: April 2020

AbstractIntroduction Lithium is the gold standard in treating bipolar affective disorders. As patients become increasingly older, drug-drug interactions leading to decreased excretion of lithium represent a key issue in lithium safety. As no study considered the effect of comedications on lithium serum concentration in combination, we aimed to quantify the impact of drugs affecting renal blood flow and function and thus potentially interacting drugs (diuretics, ACE inhibitors, AT1 antagonists, and non-steroidal anti-inflammatory drugs) on lithium serum levels in addition to age, sex, and sodium and potassium serum levels as well as renal function.Methods Retrospective data of lithium serum levels were analyzed in 501 psychiatric inpatients (2008–2015) by means of linear regression modelling.Results The number of potentially interacting drugs was significantly associated with increasing serum levels of lithium in addition to the established factors of age, renal function, and sodium concentration. Additionally, absolute lithium levels were dependent on sex, with higher values in females. However, only NSAIDs were identified to increase lithium levels independently.Discussion Routine clinical practice needs to focus on drugs affecting renal blood flow and function, especially on NSAIDs as over-the-counter medication that may lead to an increase in lithium serum concentration. To prevent intoxications, clinicians should carefully monitor the comedications, and they should inform patients about possible intoxications due to NSAIDs.
DEVELOPMENT AND PSYCHOMETRIC EVALUATION OF THE TOOL APTITUDE TOWARDS NURSING
Authors: Andrade Maxie , George Anice 
Published: April 2020

AbstractNursing is an attribute expected of every living being and every living being is capable of providing care to another in need. Few occasions especially the sickness, unawareness or disability call for special skills of nursing to substitute or supplement to the acute or chronic need of a living being. These skills can be acquired only through special training through a well planned curriculum. Hence in modern medicine, a group of health care providers called nurses are trained to care for the sick and the needy.Nursing profession has been the attraction for many young adults, however, this attraction has become the passion for some, while for few others, it is still an occupation. The transformation into an effective nurse demands special psychomotor abilities. The transformation is easier and can happen at a faster pace if one possesses an aptitude towards nursing. This assumption led the researcher to develop a tool to identify such able candidates for the profession of nursing. This article explores researcher's two attempts in developing the tool, which were though not fruitful, they certainly have given an impression on the complexity of the measurement of the construct of nursing and caring.

Abstract
Introduction This study aimed to determine the upper and lower incisors to points A and B on lateral cephalogram and study model in North Indian population. This article evaluated the present relationship of upper and lower incisors position to point A and B on the cephalogram and studied the model as a diagnostic tool for orthodontic treatment planning.
Materials and Methods The study included 32 patients, aged 15 to 25 years. The sample was divided into two groups as group I (n = 32, cephalometric analysis) and group II (n = 32, study model analysis) of the same patient. In group I incisors position was related to points A and B on the cephalograms and in group II incisors position was related to points A and B on study model by using transparent grid.
Results As per Indian norms, outcome mean value for cephalometric norms was 6.3 and 3.2 mm and for study model norms was 4 and 1.3 mm. Statistically significant differences (p < 0.002) were observed for mandibular incisor position on cephalograms and for maxillary incisors (p < 0.001) on study casts when compared with Chile sample norm.
Conclusion The anteroposterior position of upper and lower incisors in relation to points A and B on cephalogram and casts has been determined in North Indian patients.

Abstract
The first law of black hole thermodynamics has been shown to be valid in the extended phase space. However, the second law and the weak cosmic censorship conjecture have not been investigated extensively. We investigate the laws of thermodynamics and the weak cosmic censorship conjecture of an AdS black hole with a global monopole in the extended phase space in the case of charged particle absorption. It is shown that the first law of thermodynamics is valid, while the second law is violated for the extremal and near-extremal black holes. Moreover, we find that the weak cosmic censorship conjecture is valid only for the extremal black hole, and that it can be violated for the near-extremal black holes, which is different from the previous results.
The environmental neighborhoods of cities and their spatial extent
Authors: Llaguno-Munitxa M , Bou-Zeid E 
Published: April 2020

Abstract
We define the new concept of an environmental neighborhood as the surrounding area influencing the environmental quality at a given point in a city, and propose a novel methodology to measure its spatial extent. We compute the spatial correlation of air quality and urban parameters from high spatial resolution datasets for New York City, where the urban characteristics are averaged over variable urban footprint sizes, ranging from 25 m × 5 m to 5000 m × 5000 m. The scale at which these correlations peak indicates the extent of the neighboring area that influences pollutant concentrations deviations from the city-wide average. The results indicate that the scale of these environmental neighborhoods ranges from ∼1000 m (for attributes such as road area or building footmark) down to ∼200 m (for building use or green area). Selecting this optimal neighborhood scale is thus critical for identifying the urban fabric and activity attributes that have the largest influence on air quality; smaller footprints do not contain all the pertinent urban surface information while larger footprints contain irrelevant, potentially misleading information. The quantification of this scale of influence therefore enables more effective and localized policies and interventions to improve urban environmental quality and reduce urban health disparities. More broadly, the findings indicate that, in a wide range of environmental and ecological applications where surface heterogeneity is a primary driver, the scale of analysis is not an external parameter to be chosen, but rather an internal parameter dictated by the problem physics.
Tributary oscillations generated by diurnal discharge regulation in Three Gorges Reservoir

Published: April 2020

Abstract
Among the major consequences of dam construction and operation are the deterioration of water quality and the increasing frequency of occurrence of harmful algae blooms in reservoirs and their tributaries. Former studies at Three Gorges Reservoir demonstrated that the Yangtze River main stream is the main source of nutrients and pollutants to connected tributary bays. Eutrophication and other water quality problems reported for the tributaries along Three Gorges Reservoir are likely a consequence of density-driven exchange flows. Past work has focused mainly on the influence of seasonal and daily flow regulation on exchange flows, less attention has been paid to hydrodynamic processes resulting from sub-daily discharge dynamics. High-frequency measurements of flow velocity and water level in a eutrophic tributary (Xiangxi River) of Three Gorges Reservoir revealed the persistent nature of bidirectional density currents within the bay. Superimposed on this mean flow, we observed ubiquitous flow oscillations with a period of approximately 2 h. The flow variations were associated with periodic water level fluctuations with increasing amplitude for increasing distance from the river mouth (up to ±0.1 m at a distance of 27.4 km from the river mouth). They were caused by a standing wave in the tributary bay, which was generated by rapid increase or decrease in discharge following peak-shaving operation modes at Three Gorges Dam. The high-frequency wave made up the largest contribution to the temporal variance of flow velocity in the tributary bay and represents a so far overlooked hydrodynamic feature of tributaries bays in large reservoirs.

Abstract
The giant whitefly, Aleurodicus dugesii Cockerell (Hemiptera: Aleyrodidae) is a polyphagous insect which has a wide range of host plants. The insect is relatively a new pest to Indonesian agriculture. It was reported in 2008. The whitefly sucks on plant sap, extracting important nutrients that lead to defoliation, stunting and or plant death. Study of the host range and population density of the whitefly was conducted in horticultural crops at 5 villages in the Sub-district of Cipanas (Cianjur), West Java. Observation was done directly on the selected leaf samples. Twelve leaf samples were selected from four quadrants of the sample plants. The number of horticultural crops infested by the giant whitefly was 27 species consisted of 20 plant families. The most dominant host plants of the giant whitefly were families of Fabaceae, Solanaceae, and Euphorbiaceae, respectively. The highest population density of the giant whitefly was recorded on tamarillo (Solanum betaceum) as much as 1,986 per leaf. The result of this research revealed that the giant whitefly was a potential important pest which had a wide range of host plants, resulted in severe damages to horticultural crops.

Abstract

Beauveria bassiana has been widely used to control lepidopteran larvae, such as Spodoptera litura. The objective of this research was to observe the mortality and median Lethal Time (LT50) of larval S. litura after exposure of filtrate of B. bassiana cultures incubated under temperatures of 25° and 34°C. The isolates used were 10 isolates of B. bassiana and they were incubated under temperatures 25 and 34 °C in liquid media for 6 wk. The results showed that the highest mortality caused by B. bassiana was found on the fungus incubated under 25 °C and was significantly different from that of temperature 34 °C. The shortest LT50 of larval S. litura was found on the fungus incubated under temperature 25 °C and was significantly different from that of temperature 34 °C. The highest mortality was found on isolate BTmPc (96%) incubated under temperature 25 °C with the shortest LT50 (7.51 d), which was not significantly different from isolate BTmTr (93.33%) incubated under temperature 25°C with the LT50 (7.31 d). Therefore, isolate BTmTr incubated under temperature 25 °C was the most effective on killing S. litura larvae. However, isolate of BMkMs incubated under 34 °C was still caused the highest percentage of larval mortality (18.67%) and the shortest LT50 (16.20 d). Therefore, the BMkMs isolate can be developed into bio-insecticide active ingredients for controlling S. litura in tropical ecosystem.

Published: April 2020

Abstract
A dengue virus serotype 3 strain (DENV-3) was isolated in Jakarta, Indonesia. The NS3 subunit of this strain was selected for recombinant expression to determine its suitability toward later developing a subunit recombinant vaccine for dengue hemorrhagic fever. NS3 is a non-structural protein weighing approximately 72 kDa. It plays a key role in the replication cycle of the dengue virus. The successful cloning of the DENV-3 NS3 coding sequence into a pYES2/CT vector was confirmed, and Saccharomyces cerevisiae cells were transformed with this vector, followed by the expression and purification of the recombinant protein. PCR amplification and DNA sequencing confirmed the presence of the NS3 gene, and SDS-PAGE and western blot analysis produced a specific band of ∼72 kDa.

Published: April 2020

Abstract
In the current study, the antifungal activity of zinc oxide nanoparticles (ZnO NPs) against the ceiling mold isolates Penicillum sp. A1P and Cladosporium sp. A2C was examined. Antifungal activity was tested using Potato Dextrose Agar (PDA) plates supplemented with 0.1 %, 0.25 %, 0.5 % or 1.0 % (w/v) ZnO, and the growth of mold isolates on the supplemented media was observed using the slide culture method. Minimum Fungal Concentration (MFC) was determined by tube dilution method using Potato Dextrose Broth (PDB) supplemented with 0.5 %, 1.0 %, 1.5 % or 2.0 % (w/v) ZnO NP concentration. MFC was determined on the basis of Total Plate Count (TPC) obtained from tube dilution. Results from plate agar and slide cultures showed that ZnO NPs have fungistatic effects that increased with increasing ZnO NP concentration. Penicillum sp. A1P and Cladosporium sp. A2C remained biologically active; however, the spores germinated relatively slow and the diameters of resulting colonies decreased. The growth of mold isolates in supplemented broth media was notably slower than in the control, supporting the data from the plate agar and slide culture experiments. In conclusion, ZnO NPs have fungistatic against the ceiling mold isolates.

Published: April 2020

Abstract
Population and morphological data of the mangrove horseshoe crab Carcinoscorpius rotundicauda was collected off the coast of Kuala Tungkal, Tanjung Jabung Barat, Jambi, Indonesia from November 2011 to January 2012. The study site was divided into two areas: Station I (Parit 10) and Station II (Boyar), where the water was 4–8 m and 15–25 m deep, respectively. Four belt transects (5 m × 1000 m), 100 m apart, were set parallel with the shoreline in each area. Shrimp nets (5 m × 20 m), towed along the seabed by a fishing boat were used to capture crabs. The crabs were enumerated and measurements were taken of their carapace size and body weight. Abiotic factors were also measured, including water temperature, salinity, depth, and visibility. The population density of the crabs was 0.62 ± 0.23 individuals/100 m2, and their distribution pattern was random. We found correlations between depth, visibility, and crab density only at Station I.

Abstract
Urban heat mainly caused due to the anthropogenic and due to heat stored and re-radiated from the sun. In a tropical country, activity during daylight is possible in a large part of the year, and such cities rapidly contribute to influence the global climate change as Urban Heat. Education area with their activity in university is similar to an urban area with a small scale. The university campus has a localized urban environment. The land cover in an university is similar to land cover in an urban area. Every land cover has its urban heat signature. This paper aims to understand the urban heat signatures (UHS) based on the land cover on the university campus. To answer the aim of the research, we used the collected temperature data based on land cover in the education area. Data collection for the ground air surface temperature with a survey by rapid 20 min at sample location by day and night time using a handheld air temperature tool. This result concluded land cover is related to the spatial-temporal of UHS. University of Malaya campus found UHS the relation within highest vegetation covered and UHS the lowest temperature, and the other hand building covered had UHS with the highest temperature. The result saw UHS behavior in 2013 had a temperature of 1.5 °C with max temperature maximum > 30 °C for all land use cover types within UM. The vegetation-covered had UHS with the lowest temperature, and the other hand building covered had UHS with the highest temperature. The localized urban environment also gave the UHS related to vegetation covered and the building covered. The vegetation-covered relation by UHS with the lowest temp and the other hand building covered relation by UHS with the highest temp. The rest of this result gave new insight that monitoring is essential for land cover management and significant for an assessment of UHS behavior in the university campus.

Abstract
The wide use of titanium alloys is often due to their unique properties. Availability of a wide variety of mechanical, physical and chemical properties is associated with a large number of polymorphic modifications of titanium alloys. During the last decade, the metastable omega phase piques the largest interest among all titanium modifications. This study attempts to explain the different wear behavior of some titanium alloys with different Nb content during dry friction impact.
