description: To understand brain function one must have a knowledge of the organization and connectivity of neurons. Current techniques to map neuronal connectivity are either well suited to imaging synapses or well suited for large scale analysis of the brain. Fluorescence microscopy, especially when paired with CLARITY can image an entire brain, but cannot resolve synaptic junctions (~20nm). This work was undertaken to develop a tool that can circumvent this limitation and allow for detection of synapses for high throughput volumetric mapping of synapses.
The tool developed has three components; an anchor a linker and a fluorogen. The anchor is composed of the HaloTag system which covalently binds the HaloTag Ligand. The fluorogen is Malachite Green which binds to the Fluorogen Activating Protein (FAP) to become highly fluorescent. The linker is a polymeric spacer that allows the fluorogen to probe the environment around the anchor for the FAP. The HaloTag Ligand, polymer, Fluorogen unit is called a tie-dye.
The tie-dyes were synthesized with two different linker lengths; MG-halo and MG-80p-halo. Additionally, the system was tested for specificity of HaloTag-targeted FAP-signal using FAPs of two different binding affinities. The two FAPs and two tie-dyes were used to assess the effect of linker length and KD on the ability of the tie-dye to specifically bind to interacting proteins.
Specific binding of the tie-dye to dimerized fusions of the HaloTag and FAP was demonstrated for three systems. The tie-dye system demonstrated a 100% increase in signal above baseline FAP signal upon of rapamycin-induced dimerization of FKBP/FRB. EGF/EGFR proximity was detected with the tie-dye at 300% activation above baseline FAP binding. Finally, the tie-dye system was applied to the detection of membrane apposition in a model HEK293 cell system to show 450% increase in specific FAP signal at contact sites.
In all three cases, the proximity induced FAP signal is activated over background FAP fluorescence. Differences in signals above baseline FAP fluorescence depend on the relationship between tie-dye length and inter-receptor spacing, the affinity of the probe for the fluorogen activating protein, and to some extent the order with which the probe interacts with the protein tags. This validation of the tie-dyes will enable future work in application to high throughput detection of synapses. Additionally, the distance dependencies may allow this tool to act as a molecular ruler for intercellular geometries, forces, and overall dynamics.

description: We have investigated micro-photoluminescence ($μ$-PL) and excitation ($μ$-PLE) spectra of a single GaAs/AlGaAs quantum dot grown on a GaAs (411)A surface. We observed sharp resonant lines in both $μ$-PL and $μ$-PLE spectra, corresponding to the discrete energy levels of the dot. When the sample was excited at one of the resonant lines, resonant luminescence lines appear not only in Stokes side but also in anti-Stokes side. We discuss the possible origins of the anomalus anti-Stokes luminescence.

description: This paper analyzes to what extent the elected landed interests influenced the legislative process at the national level in Pakistan during the premiership of Zulfikar Ali Bhutto (1972-1977). Interestingly, in contrast to his promise of curtailing the power of the landed aristocracy, a large number of members of his party, Pakistan Peoples' Party (PPP), as well as National Assembly of Pakistan was landed aristocrats. An analysis of the debates of the National Assembly reveals that these aristocrats played a significant role in improving the plight of the poor people through legislation at the national level. Besides introducing land reforms to decrease the influence of the landed class, these legislations gave property rights to the people living in Katchi Abadis.

description: Induced breeding of crucian carp, Carassius carassius was conducted in order to determine the optimum dose of pituitary gland (PG) hormone. The research was done at the hatchery of the Freshwater Station, Bangladesh Fisheries Research Institute, Mymensingh. The study was consisted of four different doses of PG treatments (T1, T2, T3 and T4) with three replications of each. In the experiment single dose was used for T1 while double dose used for T2, T3 and T4 to evaluate the efficiency of PG hormone on ovulation, fertilization and hatching rates of C. carassius eggs. Single dose of 6.0 mg PG kg-1 body weight (bw) of female fish had no ovulatory response. The double dose in case of female fish in T2 at the rate of 6.0 mg PG kg-1 bw (1st dose 1.0 and 2nd dose 5.0 mg PG kg-1 bw at 6 h interval) and 2.0 mg PG kg-1 bw of male fish (single dose during the time of 2nd injection of female) in January showed better results in terms of ovulation (96.52±1.53%), fertilization (90.35±1.67%) and hatching rates (78.65±2.84%) compared to other treatments. Considering ovulation, fertilization and hatching rates the double dose of 6.0 mg PG kg-1 bw of female and single dose of 2.0 mg PG kg-1 bw of male can be used in induced breeding of C. carassius during January. The findings of this study indicated that induced breeding of C. Carassius is successful through PG extract and might be useful for large scale seed production in the hatchery operation.

description: This article presents a new algorithm for short-term maritime collision avoidance (COLAV) named the branching-course MPC (BC-MPC) algorithm. The algorithm is designed to be robust with respect to noise on obstacle estimates, which is a significant source of disturbance when using exteroceptive sensors such as e.g. radars for obstacle detection and tracking. Exteroceptive sensors do not require vessel-to-vessel communication, which enables COLAV toward vessels not equipped with e.g. automatic identification system (AIS) transponders, in addition to increasing the robustness with respect to faulty information which may be provided by other vessels. The BC-MPC algorithm is compliant with rules 8 and 17 of the International Regulations for Preventing Collisions at Sea (COLREGs), and favors maneuvers following rules 13-15. This results in a COLREGs-aware algorithm which can ignore rules 13-15 when necessary. The algorithm is experimentally validated in several full-scale experiments in the Trondheimsfjord in 2017 using a radar-based system for obstacle detection and tracking. The COLAV experiments show good performance in compliance with the desired algorithm behavior.

description: Limnological aspects of the Ramsagar lake, a manmade lake of Dinajpur district was studied from January 2013 to August 2013. In this experiment, five sampling points inside the Ramsagar lake were selected and water quality parameters were analyzed fortnightly. Among different physico-chemical parameters, water temperature, dissolved oxygen, total alkalinity, total hardness, phosphate-phosphorus and concentration of Chlorophyll-a did not differ significantly except the water level and pH. A total of 29 species of plankton were recorded where phytoplankton comprised of 21 species and zooplankton comprised of 8 species. Chlorophyceae was found dominant throughout the study period followed by Bacillariophyceae, Cyanophyceae and Euglenophyceae. The highest plankton cell density was observed in the month of July and lowest plankton density was observed during the month of January. The study revealed that on the basis of physical, chemical, biological and environmental conditions the water of the lake was found to be suitable for survival of aquatic flora and fauna and also suitable for fish culture.

description: Water and soil quality parameters play a vital role for sustainable shrimp and prawn production which together is the leading exportable seafood product in Bangladesh contributing to a significant amount of foreign currency earnings. However, this sector is often negatively criticized by the consumers of importing countries for farm (locally called gher in Bengali) environment. In this context, an investigation was carried out to assess water and soil quality parameters of shrimp and prawn farms in southwest Bangladesh. This study was conducted at Dumuria and Paickgacha Upazila of Khulna district during dry and wet season in 2012. The data were collected from 9 shrimp and prawn farms and they were categorized in three different groups (as treatments) including 3 prawn (T1), 3 shrimp & prawn (T2) and 3 shrimp farms (T3). Water temperature, dissolved oxygen, pH, ammonia, nitrate, nitrite, alkalinity, salinity, total phosphorous and total hardness were measured using portable advanced HACH water quality test kit in both dry and wet season. Farm soil (sediment) quality parameters including pH, organic carbon, total nitrogen and available phosphorus were measured in the laboratory in wet season. It was found that most of the water quality parameters were in suitable range in both seasons for prawn, shrimp & prawn and shrimp farming. However, the ammonia content was 0.009 to 0.45 ppm and 0.2 to 0.6 ppm in shrimp farm during dry and wet season, respectively which was higher than the other category of farms. The higher ammonia content in shrimp farm might be due to the decomposition of aquatic weeds, organic matter, uneaten feed etc. creating stress to shrimp. Different co-relationships found between the water quality parameters in all the farming systems in the both seasons. In terms of soil quality parameters such as pH, organic carbon and total nitrogen, there was no significant difference between the farm categories. However, available phosphorous content was significantly higher in shrimp & prawn farm. Phosphorous content was found negatively correlated with pH and organic carbon content of farm sediment (soil). From the present study, it could be argued that ammonia is the main problem for shrimp farms that may cause severe disease outbreak which need to be addressed from the view point of research and development towards sustainable seafood production in Bangladesh.

description: We report on a combined experimental and theoretical investigation into the normal modes of an all-fiber coupled cavity-quantum-electrodynamics system. The interaction between atomic ensembles and photons in the same cavities, and that between the photons in these cavities and the photons in the fiber connecting these cavities, generates five non-degenerate normal modes. We demonstrate our ability to excite each normal mode individually. We study particularly the `cavity dark mode', in which the two cavities coupled directly to the atoms do not exhibit photonic excitation. Through the observation of this mode, we demonstrate remote excitation and nonlocal saturation of atoms.

description: Considerable resources are invested in conserving species that may be locally, but not globally, threatened. There are a variety of motivations for such parochial conservation practices and policies, though often they are likely to be ineffective or inefficient in achieving meaningful conservation outcomes at either local or broad scales. We examine the koala in Australia as a case study of this problem as it is a species that is highly valued by the public, is only threatened over a portion of its range, and yet attracts considerable conservation effort in the portions of its range where it is in decline, especially in urban areas. We identify several approaches to koala conservation that have been favoured for many years despite the fact that they are likely to be ineffective at advancing koala conservation and suggest possible reasons for their continued use. We also identify opportunities for relatively cost-effective rural conservation that have not been adequately explored. Explicitly clarifying specific goals and objectives of conservation actions and evaluating of their efficacy would facilitate more effective prioritisation of investment of resources to improve conservation outcomes.

description: Health impact simulation models are used to predict how a proposed intervention or scenario will affect public health outcomes, based on available data and knowledge of the process. The outputs of these models are uncertain due to uncertainty in the structure and inputs to the model. In order to assess the extent of uncertainty in the outcome we must quantify all potentially relevant uncertainties. Then to reduce uncertainty we should obtain and analyse new data, but it may be unclear which parts of the model would benefit from such extra research. This paper presents methods for uncertainty quantification and research prioritisation in health impact models based on Value of Information (VoI) analysis. Specifically, we 1. discuss statistical methods for quantifying uncertainty in this type of model, given the typical kinds of data that are available, which are often weaker than the ideal data that are desired; 2. show how the expected value of partial perfect information (EVPPI) can be calculated to compare how uncertainty in each model parameter influences uncertainty in the output; 3. show how research time can be prioritised efficiently, in the light of which components contribute most to outcome uncertainty. The same methods can be used whether the purpose of the model is to estimate quantities of interest to a policy maker, or to explicitly decide between policies. We demonstrate how these methods might be used in a model of the impact of air pollution on health outcomes.

description: The in-medium properties of the vector mesons are known to be modified significantly in hot and dense hadronic matter due to vacuum polarisation effects from the baryon sector in the Walecka model. The vector meson mass drops significantly in the medium due to the effects of the Dirac sea. In the variational approach adopted in the present paper, these effects are taken into account through a realignment of the ground state with baryon condensates. Such a realignment of the ground state becomes equivalent to summing of the baryonic tadpole diagrams in the relativistic Hartree approximation (RHA). The approximation scheme adopted here goes beyond RHA to include quantum effects from the scalar meson and is nonperturbative and self--consistent. It includes multiloop effects, thus corresponding to a different approximation as compared to the one loop approximation of including scalar field quantum corrections. In the present work, we study the properties of the vector mesons in the hot and dense matter as modified due to such quantum correction effects from the baryon as well as scalar meson sectors. These medium modifications of the properties of the vector mesons are reflected, through the shifting and broadening of the respective peaks, in the low mass dilepton spectra. There is broadening of the peaks due to corrections from scalar meson quantum effects as compared to the relativistic Hartree approximation. It is seen to be rather prominent for the $ω$ meson in the invariant mass plot.

description: Purpose: To examine the phenomena governing the quantitative relationships between acentric fragments and micronuclei and understand which formulas are useful for curve-fitting of experimental data of micronuclei. Materials and methods: A stochastic model, including the phenomena of inclusion, coalescence and culling out, was developed and applied to experimental data. Results: Probabilities for inclusion/exclusion of acentric fragments into daughter nuclei and for coalescence of many fragments into a single micronucleus were found to be not cell type-specific. The biological basis for this result is explained with the lack of DNA damage checkpoints between metaphase (when acentric fragments are scored) and telophase (when micronuclei are formed). The phenomenon of “culling out” cells with high numbers of acentric fragments is also described, along with its proposed biological mechanism. Conclusions: Apart from complex formulas that describe these phenomena, we discuss which simple formulas can best approximate them and when is the case to use them for curve fitting of micronuclei data.

Analytical and numerical investigations show that the spatial spectra of the ordered state are similar to Bose-Einstein distribution, showing 1/k^2 asymptotics in the long wavelength limit. The temporal noise spectra of the ordered state are obtained of 1/^alpha form, where alpha=2-D/2 with D the spatial dimension of the system.

description: Global trade agreements in agriculture have been unsuccessful. Current explanations argue that this outcome reflects the fact that governments have motivations other than maximising social welfare. At the current state of the knowledge, there is not a suitable framework that can be used either to assess the veracity of these explanations or determine how these biases influence the international trade structure. The objective of this article is to fill this gap by proposing a formal international trade network adapted to study the issue of global agreements in agriculture. The network approach outlined here accounts for the bias of government policies towards farmers or consumers; but we also allow for intermediaries in agricultural markets that have the potential to exercise market power are largely ignored in current approaches to modelling agricultural trade. We show that accommodating these features of agricultural markets offers important insights in understanding why promoting free trade in agricultural markets has proved to be so elusive.

We find that, under coherent heteroepitaxy, Bi$_2$FeReO$_6$} exhibits a strain-driven anti-ferromagnetic insulator to ferrimagnetic semi-metal transition, while Bi$_2$FeIrO$_6$ shows correlation driven ferromagnetic insulator to ferrimagnetic half-metal transition with calculated magnetic moments of 5 $μ_B$/f.u. and 3 $μ_B$/f.u., respectively. These properties along with the low band gaps in the insulating phases make the compounds appealing for spintronics applications. Furthermore, in Bi$_2$FeIrO$_6$, the conduction and valence states are localized on different transition metal sublattices implying more efficient electron-hole separation upon photoexcitation, a desirable feature for photovoltaic applications.

description: The primary objective of this study is to examine the effect of farm size on economic efficiency among wheat producers and to suggest ways to improve wheat production in the country. Specifically, the study attempts to estimate the levels of technical, allocative and economic efficiencies among the sampled 130 large and small scale wheat producers in Nakuru District. The social-economic factors that influence economic efficiency in wheat production have also been determined. Results indicate that the mean technical, allocative and economic efficiency indices of small-scale wheat farmers are 85%, 96% and 84%, respectively. The corresponding figures for the large-scale farmers are 91%, 94% and 88%, respectively. The number of years of school a farmer has had in formal education, distance to extension advice and the size of the farm have strong influence on the efficiency levels. The relatively high levels of technical efficiency among the small scale farmers defy the notion that wheat can only be efficiently produced by the large scale farmers.

We find that the presence of WUAs provide a productivity gain of ten and eight percent for farmers at the tail end of watercourses and those that rely solely on groundwater. The productivity impact of WUAs on farmers that rely more on groundwater suggests that improving the management of surface water through functioning watercourse level institutions can be a viable option in reducing over-utilization of groundwater resources and the pressure it creates on the already strained energy situation in the country. However, we find no evidence of WUAs improving productivity for those at the head and middle of watercourses, indicating that the performance of WUAs is likely to face challenges from these groups.

description: We report on the achievement of simultaneous quantum degeneracy in a mixed gas of fermionic ^40 K and bosonic ^87 Rb. Potassium is cooled to 0.3 times the Fermi temperature by means of an efficient thermalization with evaporatively cooled rubidium. Direct measurement of the collisional cross-section confirms a large interspecies attraction. This interaction is shown to affect the expansion of the Bose-Einstein condensate released form the magnetic trap, where it is immersed in the Fermi sea.

description: It has been suggested that the absence of macroturbulence in the atmosphere of NGC 1624 - 2 is due its strong magnetic field (the strongest known for a massive O star) suppressing convection in its outer layers, removing the mechanism thought responsible for the observed macroturbulence in stars with lower field strengths. Here, we develop and apply a criterion for a uniform magnetic field to suppress convection in stellar envelopes in which radiation pressure is a significant contributor to hydrostatic balance. We find upper mass limits of ~55 Msun and ~30 Msun for magnetic suppression to be possible in Zero Age Main Sequence and Terminal Age Main Sequence stars, respectively. For evolved stars, magnetic suppression of convection can significantly alter the stars' evolution. For NGC 1624 - 2, we find a polar dipole strength of 16.5 +/- 5.9 kG is required to suppress convection, in good agreement with the value ~20 kG measured by spectropolarimetry.

description: This study examined the response of the Ghanaian pineapple production sector to the 2004/05 crisis where a swift shift of international market demand from the traditional smooth cayenne and sugar loaf variety to the MD2 variety nearly destroyed the entire fruit industry. We quantify the proportion of our sample farmers cultivating the MD2 variety and analysed the factors influencing adoption of the MD2 variety using a logistic regression model. We further employed a metafrontier analytical technique to assess the current productivity level of organic and conventional pineapple producers in three regions where commercial production for export is most concentrated. The high average performance scores (i.e. 97% mean TE and 95% mean MTR) suggests that there is not much scope for productivity gain given the current state of technology available to the industry. This implies: to substantially increase output levels in the industry to meet rapidly expanding domestic and international market demands, Government policies should aim at agricultural research development framework which not only encourages but expedite transfer of innovative production techniques to aid push output levels beyond what is currently achievable in the industry.

description: Rhythm Dungeon is a rhythm game which leverages the blockchain as a shared open database. During the gaming session, the player explores a roguelike dungeon by inputting specific sequences in time to music rhythm. By integrating smart contract to the game program, the enemies through the venture are generated from other games which share the identical blockchain. On the other hand, the player may upload their characters at the end of their journey, so that their own character may appear in other games and make an influence. Rhythm Dungeon is designed and implemented to show the potential of decentralized gaming experience, which utilizes the blockchain to provide asynchronous interactions among massive players.

description: Fairness and relevance are two important aspects of recommender systems (RSs). Typically, they are evaluated either (i) separately by individual measures of fairness and relevance, or (ii) jointly using a single measure that accounts for fairness with respect to relevance. However, approach (i) often does not provide a reliable joint estimate of the goodness of the models, as it has two different best models: one for fairness and another for relevance. Approach (ii) is also problematic because these measures tend to be ad-hoc and do not relate well to traditional relevance measures, like NDCG. Motivated by this, we present a new approach for jointly evaluating fairness and relevance in RSs: Distance to Pareto Frontier (DPFR). Given some user-item interaction data, we compute their Pareto frontier for a pair of existing relevance and fairness measures, and then use the distance from the frontier as a measure of the jointly achievable fairness and relevance. Our approach is modular and intuitive as it can be computed with existing measures. Experiments with 4 RS models, 3 re-ranking strategies, and 6 datasets show that existing metrics have inconsistent associations with our Pareto-optimal solution, making DPFR a more robust and theoretically well-founded joint measure for assessing fairness and relevance.

description: Trust plays a key role in promoting cooperation, exchanges, and interactions among individuals and therefore it is believed to foster economic and societal development. Sender's behaviour in the popular "investment game" (Berg et al. 1995) is widely employed to measure trust among individuals, but recent economic literature has cast doubts on the accuracy of this measure of trust. These studies, however, were mostly conducted in controlled environmentsm having university students as subject polls. We played the "investment game" with 3320 rural households from 200 villages in the Adamawa region of Cameroon, recording for each participant his expectations of return on the edowment shared as first mover. In addition, participants played two additional games obtained by separating the "investment game" into two sub-games, "Triple dictator game" and "reverse triple dictator game"/ The latter two games were used to measure participants' altruism and distributional preferences. All participants were randomly assigned to two treatments with different secrecy levels to create exogenous variation in social pressure, and measure the effect of social norms on behaviour in investment game. We use behaviour observed in the sub games to test whether senders behaviour in the investment game only measures trust (and therefore a belief in someone else's trustworthiness), and whether trustworthiness in turn is a reciprocation of kindness with kindness, or unkindness with unkindness. We control for risk preferences and other demographics, and find that senders behaviour in the investment game measures mostly trust, but it is not an accurate measure of trust.

description: Abstract: Background: Whether a modestly elevated homocysteine level is causally associated with an increased risk of cardiovascular disease remains unestablished. We conducted a Mendelian randomization study to assess the associations of circulating total homocysteine (tHcy) and B vitamin levels with cardiovascular diseases in the general population. Methods: Independent single nucleotide polymorphisms associated with tHcy (n = 14), folate (n = 2), vitamin B6 (n = 1), and vitamin B12 (n = 14) at the genome-wide significance level were selected as instrumental variables. Summary-level data for 12 cardiovascular endpoints were obtained from genetic consortia, the UK Biobank study, and the FinnGen consortium. Results: Higher genetically predicted circulating tHcy levels were associated with an increased risk of stroke. For each one standard deviation (SD) increase in genetically predicted tHcy levels, the odds ratio (OR) was 1.11 (95% confidence interval (CI), 1.03, 1.21; p = 0.008) for any stroke, 1.26 (95% CI, 1.05, 1.51; p = 0.013) for subarachnoid hemorrhage, and 1.11 (95% CI, 1.03, 1.21; p = 0.011) for ischemic stroke. Higher genetically predicted folate levels were associated with decreased risk of coronary artery disease (ORSD, 0.88; 95% CI, 0.78, 1.00, p = 0.049) and any stroke (ORSD, 0.86; 95% CI, 0.76, 0.97, p = 0.012). Genetically predicted increased vitamin B6 levels were associated with a reduced risk of ischemic stroke (ORSD, 0.88; 95% CI, 0.81, 0.97, p = 0.009). None of these associations persisted after multiple testing correction. There was no association between genetically predicted vitamin B12 and cardiovascular disease. Conclusions: This study reveals suggestive evidence that B vitamin therapy and lowering of tHcy may reduce the risk of stroke, particularly subarachnoid hemorrhage and ischemic stroke.
