description: The ruthenium(III)-catalyzed electron-transfer reaction between hexacyanoferrate(III) and ranitidine hydrochloride is studied in alkaline medium at 25°C and at an ionic strength of 1.10 mol/dm3. The reaction stoichiometry is established and is found to be 1:4, that is, for the oxidation of one mole of ranitidine, four moles of hexacyanoferrate(III) are consumed. The reaction products were characterized by spectral studies such as IR, GC-MS, 1H-NMR and 13C-NMR. The reaction rate shows a less than unit order in substrate and alkali and a first-order dependence in oxidant, [Fe(CN)6]3− and the catalyst, ruthenium(III) concentrations. The active species of ruthenium(III), [Ru(H2O)5OH]2+, forms an intermediate complex with the substrate. The attack of complex by hexacyanoferrate(III) in the rate determining step produces a radical cation, which is further oxidized in the subsequent step to form the oxidation product. The effect of the reaction environment on the rate constant upon adding varying concentrations of KNO3 and t-butanol was studied. The initially added products did not have any significant effect on the reaction rate. A plausible mechanism is proposed based on the experimental results. The effect of varying temperature on the reaction rate was also studied. The activation parameters for the slow step and the thermodynamic quantities for the equilibrium steps were evaluated.The mechanism of title reaction has been studied and one mole of ranitidine consumes four moles of [Fe(CN)6]3−, as shown in the following equation:

description: The unique biodiversity in Malaysia makes this country a global hotspot for different aspects of research. Many European and non-native research activities are conducting by different research groups, whereas local institutions also collaborate with them to explore the pristine nature of west (peninsular Malaysia) and East Malaysia (Sarawak and Sabah province). East Malaysia is located in Borneo Island, and the biodiversity of this area are huge. The current review work scrutinized the information about the research activities on aquatic bivalve species and their different aspects of the investigation. This investigation revealed, to date 28 research publications were published on aquatic bivalves from eastern Malaysia, where biodiversity, conservation and ecology was the major aspect of research. The other aspects were aquaculture, natural history and taxonomy, nutritional study, reproduction of bivalve, morphology, and pollution can be mentionable. The major portion of this eastern Malaysia are not investigated and it is assumed that many species are still not reported. Further studies demand to explore the vast bivalve biodiversity of this part of Malaysia.

description: High absolute accuracy is an essential prerequisite for a humanoid robot to autonomously and robustly perform manipulation tasks while avoiding obstacles. We present for the first time a kinematic model for a humanoid upper body incorporating joint and transversal elasticities. These elasticities lead to significant deformations due to the robot's own weight, and the resulting model is implicitly defined via a torque equilibrium. We successfully calibrate this model for DLR's humanoid Agile Justin, including all Denavit-Hartenberg parameters and elasticities. The calibration is formulated as a combined least-squares problem with priors and based on measurements of the end effector positions of both arms via an external tracking system. The absolute position error is massively reduced from 21mm to 3.1mm on average in the whole workspace. Using this complex and implicit kinematic model in motion planning is challenging. We show that for optimization-based path planning, integrating the iterative solution of the implicit model into the optimization loop leads to an elegant and highly efficient solution. For mildly elastic robots like Agile Justin, there is no performance impact, and even for a simulated highly flexible robot with 20 times higher elasticities, the runtime increases by only 30%.

description: ABSTRACTThe wheat stem sawfly, Cephus cinctus (Hymenoptera: Cephidae) is the major pest of wheat in the northern plains of North America, with biological control providing a potentially useful management tool. Foreign exploration by the USDA-ARS identified Collyria catoptron (Hymenoptera: Ichneumonidae), a parasitoid wasp of Cephus fumipennis in northern China, as a potential biological control agent. Here we carry out a preliminary evaluation of the potential suitability of C. catoptron, as a candidate agent against C. cinctus. Specifically we: (1) Quantify the spatio-temporal variation in parasitism rates on the native host from collection sites in northern China over six years, and (2) Assess whether C. catoptron will oviposit and complete development in the novel targeted host. Maximum parasitism of the native host in the native range was 38%, exceeding the theoretical threshold for successful biological control. Site occupancy levels were high (83%) suggesting good colonisation abilities. C. catoptron clearly recognised and attacked C. cinctus, with parasitism levels exceeding those observed on the co-evolved host C. fumipennis. However, we found no evidence that C. catoptron can complete development in C. cinctus; no adults were reared from this host in either year of the study. In contrast 50–60% of the parasitoids survived to emerge as adults in C. fumipennis. Thus, C. catoptron is unlikely to be a suitable agent against C. cinctus due to basic host incompatibility. Future work will be directed towards developing conservation biological control approaches using native parasitoid species already present in the USA.

description: When a humanoid robot performs a manipulation task, it first makes a model of the world using its visual sensors and then plans the motion of its body in this model. For this, precise calibration of the camera parameters and the kinematic tree is needed. Besides the accuracy of the calibrated model, the calibration process should be fast and self-contained, i.e., no external measurement equipment should be used. Therefore, we extend our prior work on calibrating the elastic upper body of DLR's Agile Justin by now using only its internal head-mounted RGB camera. We use simple visual markers at the ends of the kinematic chain and one in front of the robot, mounted on a pole, to get measurements for the whole kinematic tree. To ensure that the task-relevant cartesian error at the end-effectors is minimized, we introduce virtual noise to fit our imperfect robot model so that the pixel error has a higher weight if the marker is further away from the camera. This correction reduces the cartesian error by more than 20%, resulting in a final accuracy of 3.9mm on average and 9.1mm in the worst case. This way, we achieve the same precision as in our previous work, where an external cartesian tracking system was used.

description: In the present work we propose to design drugs that target the enzyme dihydrofolate redutase (DHFR) as a means of a novel drug therapy against plague. Potential inhibitors of DHFR from Yersinia pestis (YpDHFR) were selected by virtual screening and subjected to docking, molecular dynamics (MD) simulations and Poisson−Boltzmann surface area method (MM-PBSA), in order to evaluate their interactions in the active sites of YpDHFR and human DHFR (HssDHFR). The results suggested selectivity for 3 compounds that were further used to propose the structures of 6 new potential selective inhibitors for YpDHFR.

description: Planning collision-free motions for robots with many degrees of freedom is challenging in environments with complex obstacle geometries. Recent work introduced the idea of speeding up the planning by encoding prior experience of successful motion plans in a neural network. However, this "neural motion planning" did not scale to complex robots in unseen 3D environments as needed for real-world applications. Here, we introduce "basis point set", well-known in computer vision, to neural motion planning as a modern compact environment encoding enabling efficient supervised training networks that generalize well over diverse 3D worlds. Combined with a new elaborate training scheme, we reach a planning success rate of 100%. We use the network to predict an educated initial guess for an optimization-based planner (OMP), which quickly converges to a feasible solution, massively outperforming random multi-starts when tested on previously unseen environments. For the DLR humanoid Agile Justin with 19DoF and in challenging obstacle environments, optimal paths can be generated in 200ms using only a single CPU core. We also show a first successful real-world experiment based on a high-resolution world model from an integrated 3D sensor.

description: Growth and production of near threatened Ompok pabda (Hamilton) were examined at different feeding frequencies in the present study. The experiment was conducted for four months in three earthen ponds from 1 st April to 31 st July 2018 at Tanore Upazila in Rajshahi district, Bangladesh. The experiment was performed using pabda, (Ompok pabda) fingerling (average) to study the effect of feeding frequency on growth performance. The study carried out considering three treatments, namely T 1 , T 2, and T 3 ; while the feeding frequency was two times per day in treatment T 1 , three times per day in treatment T 2, and four times per day in treatment T3. Fish were fed considering three-stage of life span; these were fingerling stage, early growing stage, and growing stage. In the fry stage, the fishes were fed 20% feed, in the fingerlings stage the fish were fed 10% feed and in the growing stage, the fish were fed 8% feed of the body weight. The mean water temperature ranged between 27.13±2.10 and 27.29±2.16 °C among treatments, while water transparency ranged between 31.91±1.58 and 29.96±1.84 cm. pH ranged between 7.62±0.14 and 7.70±0.19; while the mean dissolved oxygen was ranged between 5.35±0.11 and 5.56±0.14 among treatments. The final weight gain was found to be highest (56.36±0.01) in the treatment T 2 and lowest (38.23±0.01) in the treatment T3. The SGR value was higher (3.94±0.01) in the treatments T 2 followed by treatments T 1 and T 3. Net weight gain was significantly (p<0.05) higher in feeding frequency three (56.36±0.1), followed by feeding frequency four (38.23±0.1) and feeding frequency two (40.67±0.73). The FCR value ranged between 1.90 and 2.87 among treatments. The growth performance and specific growth rate were significantly (p<0.05) higher in feeding frequency three. The highest (4049.1±0.1 kg/ha/120 days) production was observed in T2. Best cost benefit ratio was gained in treatment T2 .

description: Choropleth representation has been the most widely applied method to represent rates in disease maps due to its consistency in depicting relative data. However polygons in a choropleth map may give the erroneous notion of homogenous distribution over area in cases where the mapped quantity varies in its spatial distribution. In the case of population maps, choropleth maps suggest uniform distribution of people within large peri-urban administrative areas where population is known to be unevenly distributed within the administrative units. Dasymetric mapping can provide a more accurate and detailed distribution of population data by using ancillary information to spatially disaggregate population within administrative units. We have developed a procedure to use more detailed fiscal cadastre blocks to disaggregate census data within less detailed enumeration and sample areas. Here we explain the procedure and provide simple examples of this dasymetric representation as applied to population density, socioeconomic and health indicators. This approach may help to identify fine-scale risk patterns of infectious and chronic diseases and associated socioeconomic or environmental risk factors. It is hoped that better visualization through this approach will help specialists in planning to reduce social injustice in complex urban environments.

description: In this study, we report the synthesis and biological evaluation of novel phthalimide based Schiff base derivatives as promising antioxidant and DNA binding agents. The structural investigation of the synthesized compounds was determined by spectral and elemental analysis. In vitro DNA binding studies of title compounds were carried out by UV–Vis., fluorescence, circular dichroism spectroscopic techniques, cyclic voltammetry, thermal denaturation studies and hydrodynamic measurements to investigate their potential as DNA binding agents. The intrinsic binding constant (Kb) of target compounds obtained from absorption studies between 1.2 × 105 M−1 and 1.27 × 105 M−1 respectively, suggesting that the test compounds have shown good affinity towards Calf-thymus DNA. The experimental results of DNA-binding studies reveal a non-intercalative mode of binding between DNA and the synthesized compounds, most probably groove binding. In addition, molecular docking techniques were performed to rationalize the observed binding affinities with the target DNA. Furthermore, antioxidant and free radical scavenging activities of the synthesized compounds were carried out to find out their pharmacological potential. The results indicate that the title compounds displayed good antioxidant activity against DPPH (IC50: 0.727 and 0.656 mg/mL) and H2O2 radicals (IC50: 1.072 and 0.911 mg/mL) comparable to standard ascorbic acid.

description: Given a dataset with many features observed in a large number of conditions, it is desirable to fuse and aggregate conditions that are similar to ease the interpretation and extract the main characteristics of the data. This article presents a multidimensional fusion penalty framework to address this question when the number of conditions are large. If the fusion penalty is encoded by an ℓq-norm, we prove for uniform weights that the path of solutions is a tree that is suitable for interpretability. For the ℓ1 and ℓ∞-norms, the path is piecewise linear and we derive a homotopy algorithm to recover exactly the whole tree structure. For weighted ℓ1-fusion penalties, we demonstrate that distance-decreasing weights lead to balanced tree structures. For a subclass of these weights that we call “exponentially adaptive,” we derive an O(nlog(n)) homotopy algorithm and we prove an asymptotic oracle property. This guarantees that we recover the underlying structure of the data efficiently both from a statistical and a computational point of view. We provide a fast implementation of the homotopy algorithm for the single feature case, as well as an efficient embedded cross-validation procedure that takes advantage of the tree structure of the path of solutions. Our proposal outperforms its competing procedures on simulations both in terms of timings and prediction accuracy. As an example we consider phenotypic data: given one or several traits, we reconstruct a balanced tree structure and assess its agreement with the known taxonomy.

description: In this paper we study youth migration in Russia at the sub-regional level of
administrative division. The aim of the research is to assess the volume of internal youth
migration. The task is only doable with the use of census data, which not only allows us
to research at the sub-regional level, but also provides much more accurate information
on youth migration than the current migration record does. We used the survival method
to study sub-regional population dynamics. As mortality is quite insignificant at young
ages, most of the change in cohort size is caused by migration. Our estimates show that
during the last intercensus period (2003-2010) up to 70 percent of youth cohorts have
left the regional periphery for good after graduating from school, and there was no
significant return to the demographically depleted periphery in the young working ages.

description: A broad variety of aquaculture-related medications, drugs, and chemicals (AMDC) are extensively used in the aquaculture industry in SouthEastern Bangladesh. Fish farmers are worried about the quality of their final product, and disease outbreaks must be stopped at all costs. Farmers are sometimes one ahead of the curve when it comes to producing healthy final products by including probiotics, vitamins, and minerals into their aquaculture setups to promote early and disease-free output. However, the current study was carried out in south eastern Bangladesh, specifically in the highly dense aquaculture regions of Chandpur, Cumilla, and Feni district (17 upazilas), from November 2016 to January 2018. Questions were asked through interviews and a Focus Group Discussion (FGD) was held to gather primary data. The major target groups were aquaculture farmers, AMDC shops, pharmaceutical company employees, and hatchery owners. In this three-county area, according to the findings from the thorough research, there are a total of 33 companies that advertise 330 generics brand products via their own distributional channels. Among the available AMDC products in the study area, growth promoters were mostly abundant products among all categories while other products such as predator removal products, insecticides and ectoparasiticides, water quality and pond management, plankton producer, plankton bloom cleaner, disinfectant and disease treatment, toxic gas reducer, pH controller, oxygen supply, stress reducer, growth promoter, probiotics and antibiotics were most selling products to the farmers. The present study revealed 19 generic of antibiotics were available and prescribed by the AMDC vendors or aquaculture disease consultants (ADC) around the regions. Additionally, the research also included the dosages of AMDC and the method of administration in the aquaculture pond, which will assist both the farmers and the ADC in selecting and suggesting the appropriate medications or treatments that may be beneficial to the farmers in the long run.

description: Our objective was to assess the association between amyotrophic lateral sclerosis (ALS) and other neurodegenerative diseases such as Alzheimer's disease (AD), frontotemporal dementia (FTD) and Parkinson's disease (PD). From May 2007 through August 2012 we investigated 146 patients with newly diagnosed ALS and 146 age- and gender-matched controls. Each individual was screened for cardinal extrapyramidal signs (neurological examination) and cognitive dysfunction (Mini Mental State Examination, MMSE and Frontal Assessment Battery, FAB). Results demonstrated that rigidity was present in 8.2% of cases and 2.1% of controls (adjusted odds ratio, adjOR 5.7; 95% CI 1.5–22.0). The corresponding percentages for bradykinesia and postural instability were, respectively, 8.2 vs. 2.7% (adjOR 4.8; 95% CI 1.4–16.5) and 2.7 vs. 9.6% (adjOR 0.3; 95% CI 0.1–0.9). FAB ≤ 13.4 was recorded in 24.8 vs. 9.6%; adjOR 2.9; 95% CI 1.5–5.7). Tremor and abnormal FAB score were predicted by an older age at onset while an abnormal FAB score was associated with cramps and family history of neurodegenerative diseases. In conclusion, our data support the notion that newly diagnosed ALS carries a higher than expected risk of extrapyramidal signs and FTD.

description: Our objective was to describe amyotrophic lateral sclerosis (ALS) mortality rates in the Chilean population over a 17-year period. Chilean death records (1994–2010) were reviewed for the ICD-10 diagnosis G.12.2 (including motor neuron disease and similar conditions), and weighted with population data. Crude and standardized mortality rates by ALS were calculated at the nationwide level and by geographic zone. A risk analysis was performed in successive cohorts from 1910–1919 to 1960–1969, comparing mortality slopes. One thousand six hundred and seventy-one deaths were recorded during 1994–2010, with an average of 1.13 per 100,000, a 1.2:1 male/female ratio, and a statistically significant increase in mortality rate. According to geographical distribution, the Austral area, with a larger population of European origin, showed higher mortality rates compared to the national average. The cohort analysis showed an increasing risk of dying from ALS for all cohorts, and highest above 64 years of age, becoming a competitive cause of death in older ages.In conclusion, as expected, the mortality rate in Chile by ALS is higher than that reported previously in our country, and similar to other Latin American countries. ALS mortality rate has increased over time probably due to the aging of the population and decline in rates for competing causes of death.

description: Caffeine is thought to be neuroprotective by antagonizing the adenosine A2A receptors in the brain and thereby protecting motor neurons from excitotoxicity. We examined the association between consumption of caffeine, coffee and tea and risk of amyotrophic lateral sclerosis (ALS).Longitudinal analyses based on over 1,010,000 males and females in five large cohort studies (the Nurses’ Health Study, the Health Professionals Follow-up Study, the Cancer Prevention Study II Nutrition Cohort, the Multiethnic Cohort Study, and the National Institutes of Health-AARP Diet and Health Study). Cohort-specific multivariable-adjusted risk ratios (RR) and 95% confidence intervals (CI) estimates of ALS incidence or death were estimated by Cox proportional hazards regression and pooled using random-effects models. Results showed that a total of 1279 cases of ALS were documented during a mean of 18 years of follow-up. Caffeine intake was not associated with ALS risk; the pooled multivariable-adjusted RR comparing the highest to the lowest quintile of intake was 0.96 (95% CI 0.81–1.16). Similarly, neither coffee nor tea was associated with ALS risk. In conclusion, the results of this large study do not support associations of caffeine or caffeinated beverages with ALS risk.

description: The objectives of this study were to explore current provision of laparoscopic simulation training, and to determine attitudes of trainers and trainees to the role of simulators in surgical training across the UK. An anonymous cross-sectional survey with cluster sampling was developed and circulated. All Royal College of Obstetricians and Gynaecologists (RCOG) Training Programme Directors (TPD), College Tutors (RCT) and Trainee representatives (TR) across the UK were invited to participate. One hundred and ninety-six obstetricians and gynaecologists participated. Sixty-three percent of hospitals had at least one box trainer, and 14.6% had least one virtual-reality simulator. Only 9.3% and 3.6% stated that trainees used a structured curriculum on box and virtual-reality simulators, respectively. Respondents working in a Large/Teaching hospital (p = 0.008) were more likely to agree that simulators enhance surgical training. Eighty-nine percent agreed that simulators improve the quality of training, and should be mandatory or desirable for junior trainees. Consultants (p = 0.003) and respondents over 40 years (p = 0.011) were more likely to hold that a simulation test should be undertaken before live operation. Our data demonstrated, therefore, that availability of laparoscopic simulators is inconsistent, with limited use of mandatory structured curricula. In contrast, both trainers and trainees recognise a need for greater use of laparoscopic simulation for surgical training.

description: Capsule Abundance monitoring data suggest that the short-term response of breeding birds to recent warming in Great Britain has been range expansion, caused by poleward shifts of leading range margins and no significant shifts of trailing range margins.Aims To quantify latitudinal and elevational shifts of breeding bird populations in Great Britain and test for differential shifts in range margins during a period of warming (1994–2009).Methods We modelled the population density of 80 species as a smooth function of latitude, longitude, elevation and year. Reference points on the distribution curve were used to describe latitudinal and elevational shifts.Results Across species, poleward shifts in the leading range margin were greater than in the range-centre. The trailing range margin was largely static, providing evidence for significant range expansion. The magnitude of latitudinal range shift lagged behind the equivalent shift in temperature, suggesting that species may be accumulating a climatic debt. There was no evidence for consistent elevational shifts.Conclusion Contrary to the generally expected long-term consequences of climate change of range contraction, we show that the short-term response to recent warming has been range expansion. This suggests the mechanisms of short-term and long-term consequences of climate change may differ.

description: Malawi’s unique flora and fauna are threatened by high levels of deforestation and forest degradation. In addition to the many ecosystem services provided by the country’s forests, most of the rural population of this poor country are highly dependent on forests for provision of food, firewood, medicine, building materials and income. This study examined farmers’ attitudes and behaviour in relation to cutting down forest trees in two rural districts in Malawi using the theory of planned behaviour as a conceptual framework. A survey was administered to 200 household heads in Mzimba and Chiradzulu districts. With strongly negative attitudes, subjective norms and perceived behavioural control, farmers were aware of the negative consequences associated with cutting down forest trees, the lack of social support and obstacles encountered when cutting down forest trees. The intention to cut down forest trees was generally low. However, farmers were highly dependent on forest resources, especially in the north, which is caused by high levels of poverty and a lack of alternative income opportunities. We conclude that poverty alleviation and livelihood diversification are crucial for addressing the overexploitation of forest trees in Malawi.

How to Hackathon: Socio-technical Tradeoffs in Brief, Intensive Collocation

description: Hackathons are events where people who are not normally collocated converge for a few days to write code together. Hackathons, it seems, are everywhere. We know that long- term collocation helps advance technical work and facilitate enduring interpersonal relationships, but can similar benefits come from brief, hackathon-style collocation? How do participants spend their time preparing, working face-to- face, and following through these brief encounters? Do the activities participants select suggest a tradeoff between the social and technical benefits of collocation? We present results from a multiple-case study that suggest the way that hackathon-style collocation advances technical work varies across technical domain, community structure, and expertise of participants. Building social ties, in contrast, seems relatively constant across hackathons. Results from different hackathon team formation strategies suggest a tradeoff between advancing technical work and building social ties. Our findings have implications for technology support that needs to be in place for hackathons and for understanding the role of brief interludes of collocation in loosely-coupled, geographically distributed work.
