description: Voltage-gated sodium (Nav) channels constitute a prime target for drug design and discovery, given their implication in various diseases such as epilepsy, migraine and ataxia to name a few. In this regard, performing morphological analysis is a crucial step in comprehensively understanding their biological function and mechanism, as well as in uncovering subtle details of their mechanism that may be elusive to experimental observations. Despite their tremendous therapeutic potential, drug design resources are deficient, particularly in terms of accurate and comprehensive geometric information. This paper presents a geometric dataset of molecular surfaces that are representative of Nav channels in mammals. For each structure we provide three representations and a number of geometric measures, including length, volume and straightness of the recognized channels. To demonstrate the effective use of GEO-Nav, we have tested it on two methods belonging to two different categories of approaches: a sphere-based and a tessellation-based method.
Smallholder Agriculture Production in Zimbabwe: A Survey

description: The study focuses on smallholder agriculture production in Zimbabwe as a pathway for fighting rural poverty and underdevelopment. The entitlement approach was used to analyse the agriculture issues of smallholder farmers. Using questionnaires and interviews to gather household data the study employed quantitative and qualitative data analysis through spreadsheet and Atlas Ti analysis. The study revealed that smallholder agriculture in Zimbabwe is predominantly staple production, with cash cropping more prevalent to resettlement areas. Poverty remains deeply entrenched in communal areas where land tenure systems, input supply programs and farmer representations are detrimental to the sector development. Revitalising smallholder agriculture would provide pathways of nearly 7 million people in rural Zimbabwe out of poverty. Thus development would need a refocus of policy conditions in communal areas to allow smallholder agriculture growth and development.

description: In this work, the effect on crystallite orientation, surface morphology, fractal geometry, structural coordination and electronic environment of DC magnetron sputtered AlN films were investigated. X-ray diffraction results disclosed that the c-axis orientation of AlN films increased with the preferred wurtzite hexagonal structure above 17% N2 flow. X-ray reflectivity data confirmed AlN film density increased with increasing N2 flow and was found to be 3.18g/cm3 for 40% N2. The transition of electrons from N 1s to 2p states hybridized with Al 3p states because of π* resonance was obtained from X-ray absorption spectroscopy of the N K-edge. The semi-empirical coordination geometry of nitrogen atoms has been studied by deconvolution of N K-edge. The surface composition of AlN films at 40% N2 consists of 32.08, 51.94 and 15.97at.% Al, N and O respectively. Blue-shifting of A1(LO) and E1(LO) modes in the Raman spectra at phonon energies 800 and 1051cm-1 respectively was most likely due to the presence of oxygen bonds in the AlN films.

description: Let K be a (commutative) field, and U and V be finite-dimensional vector spaces over K. Let S be a linear subspace of the space L(U,V) of all linear operators from U to V. A map F from S to V is called range-compatible when F(s) belongs to the range of s for all s in S. Obvious examples of such maps are the evaluation maps s -> s(x), with x in U. In this article, we classify all the range-compatible group homomorphisms on S provided that the codimension of S in L(U,V) is less than or equal to 2 dim(V)-3, unless this codimension equals 2 dim(V)-3 and K has only two elements. Under those assumptions, it is shown that the linear range-compatible maps are the evaluation maps, and the above upper-bound on the codimension of S is optimal for this result to hold. As an application, we obtain new sufficient conditions for the algebraic reflexivity of an operator space and, with the above conditions on the codimension of S, we give an explicit description of the range-restricting and range-preserving homomorphisms on S.

description: We construct a modular desingularisation of $\overline{\mathcal{M}}_{2,n}(\mathbb{P}^r,d)^{\text{main}}$. The geometry of Gorenstein singularities of genus two leads us to consider maps from prestable admissible covers: with this enhanced logarithmic structure, it is possible to desingularise the main component by means of a logarithmic modification. Both isolated and non-reduced singularities appear naturally. Our construction gives rise to a notion of reduced Gromov-Witten invariants in genus two.
description: 47 pages, 13 figures, comments are welcome! v2: minor expository improvements throughout the paper. v3: the main construction (Section 3) has been split into two steps, the second of which addresses the hyperelliptic components, with the advantage of simplifying the singularities that we have to introduce.

description: Poly(3,4-ethylenedioxythiophene) : poly(styrene sulfonic acid (PEDOT:PSS), an optically transparent organic semi-conductor, constitutes a suspension of conducting PEDOT:PSS grains, shelled by an insulating layer of PSS. While a percolation network enhances dc conductivity, structural and electrical inhomogenity hinters electric charge flow giving rise to capacitance effects. In the present work, two distinct relaxation mechanisms are detected by Broadband Dielectric Spectroscopy (BDS). Double polarization mechamisms are predicted by bi-phase suspension dielectric theory. Within the frame of interfacial polarization, we propose a methodology to have an insight into the local conductivity of the interior of mesoscopic conducting phase.

description: The following paper is meant to be practical, in that it offers an impact assessment model for web-based time banks that was produced as a consultancy project deliverable; and academic, in that it offers a thought-experiment about the measurement of social capital and its association with sustainable development. As the development field continues to transition towards sustainable models that include social variables, innovative impact assessment tools are needed to fully understand the role of these variables for planning and investment. Web-based time banks – online networks that members exchange services by using an alternative currency in the form of time – offer an opportunity to look at the operationalization of social variables in a unique way, particularly social capital and its relationship to economic development. The impact assessment model seeks to answer: how do time banks as a development intervention augment the social capital of communities? The model was designed based on three dimensions of social capital, psychological, social and economic, and Edgar Cahn’s theory of co-production. The model contributes to the economic valuation of time bank participation through the metrics: Market Value Savings and Economic Risk of Participation.

description: Within a confining quark matter model which considers phenomenologically the quark confinement and asymptotic freedom as well as the chiral symmetry restoration and quark deconfinement at high baryon density, we find that if the up-down quark matter ($ud$QM) is more stable than nuclear matter and strange quark matter (SQM), the maximum mass of static quark stars with $ud$QM is $2.87M_{\odot}$ under agreement with both the constraints on star tidal deformability from gravitational wave signal GW170817 and the mass-radius of PSR J0030+0451 and PSR J0740+6620 measured by NICER. In contrast, the conventional strange quark star with the SQM that is more stable than nuclear matter while the nuclear matter is more stable than $ud$QM, has a maximum static mass of only $1.87M_{\odot}$ and its radius significantly deviates from NICER's constraint. Our results thus provide circumstantial evidence suggesting the recently reported GW190814's secondary component with a mass of $2.59^{+0.08}_{-0.09}M_\odot$ could be an up-down quark star.

description: The present paper introduces stochastic velocity as improvement for moving particle semi-implicit (MPS) method. This improvement is to overcome energy loss caused by numerical dissipation in the basic MPS that brings about rapid decay of waves. Stochastic velocity is added in the explicit step of the basic MPS method. MPS with stochastic improvement is compared with the basic method in the case of linear water waves, in particular dam break problem and standing wave in a rectangular tank. Surface detection and curve fitting are used to analyze the parameters of wave on the standing wave case. The surface detection and curved fitting was efficient to determine parameters of the wave and it was found that the stochastic improvement made the waves survived longer than in the basis method.

description: The binary star alpha Aurigae (otherwise known as Capella) is extremely important to understand the core hydrogen and helium burning phases of the stars, as the primary star is likely evolving through the core helium burning phase, and the masses of the two components are 2.5 Msun and 2.6 Msun, which fall into a mass range for which the extention of the core overshoot during the main sequence phase is uncertain. We aim at deriving the extent of the core overshoot experienced during the core burning phases and testing the efficiency of the convective transport of energy in the external envelope, by comparing results from stellar evolution modelling with the results from the observations. We consider evolutionary tracks calculated on purpose for the present work, for the primary and secondary star of Capella. We determine the extent of the extra-mixing from the core during the main sequence evolution and the age of the system, by requiring that the effective temperatures and surface gravities of the model stars reproduce those derived from the observations at the same epoch. We further check consistency between the observed and predicted surface chemistry of the stars. Consistency between results from stellar evolution modelling and the observations of Capella is found when extra-mixing from the core is assumed, the extent of the extra-mixed zone being of the order of 0.25 H_P. The age of the system is estimated to be 710 Myr. These results allow to nicely reproduce the observed surface chemistry, particularly the recent determination of the 12C/13C ratio based on LBT (Large Binocular Telescope) and VATT (Vatican Advanced Technology Telescope) observations

description: Large-scale urban development, not to mention synthetic urbanization, will not remain sustainable absent structural changes to the normative and decision making framework that include rolling technology assessment and systems analysis. Technology policies need to be based on outcomes as well as on significant improvements in complexity management at critical stages of planning and implementation. This conclusion endures even if it requires limiting options of political decision making in open democratic societies through normative structural automatisms. Independent of political trends, social consensus almost everywhere favors a prioritization of energy efficiency, alternative energies, resource recycling, urban farming, cost- and time-effective public transportation, water economy, and extended product life. But public interest-driven decision making processes, legislation, and dispute resolution do not adequately take into account the acceleration of technological innovation on the one hand, and of environmental deterioration on the other hand. This paper exposes fundamental weaknesses and future needs for technology assessment drawing on European, American and global experiences. It highlights challenges to avoid possible crises of legitimacy and anti-technology groundswells of Luddite proportions as well as forgoing groundbreaking opportunities for an open knowledge society based on informed consent rather than state mandate.

description: Infrared spectroscopic ellipsometry is applied to investigate the free-charge carrier properties of Mg-doped InN films. Two representative sets of In-polar InN grown by molecular beam epitaxy with Mg concentrations ranging from $1.2\times10^{17}$ cm$^{-3}$ to $8\times10^{20}$ cm$^{-3}$ are compared. P-type conductivity is indicated for the Mg concentration range of $1\times10^{18}$ cm$^{-3}$ to $9\times10^{19}$ cm$^{-3}$ from a systematic investigation of the longitudinal optical phonon plasmon broadening and the mobility parameter in dependence of the Mg concentration. A parameterized model that accounts for the phonon-plasmon coupling is applied to determine the free-charge carrier concentration and mobility parameters in the doped bulk InN layer as well as the GaN template and undoped InN buffer layer for each sample. The free-charge carrier properties in the second sample set are consistent with the results determined in a comprehensive analysis of the first sample set reported earlier [Schöche et al., J. Appl. Phys. 113, 013502 (2013)]. In the second set, two samples with Mg concentration of $2.3\times10^{20}$ cm$^{-3}$ are identified as compensated n-type InN with very low electron concentrations which are suitable for further investigation of intrinsic material properties that are typically governed by high electron concentrations even in undoped InN. The compensated n-type InN samples can be clearly distinguished from the p-type conductive material of similar plasma frequencies by strongly reduced phonon plasmon broadening.

description: In my short essay in honor of Karl-Alex Mueller, I would like to deal with some aspects that have been on my mind since the beginning of my own research. Some of the facts and questions mentioned here have been known or clarified for a long time, others not. For example, I think that the fact that superconductivity occurs almost spontaneously in many cuprates close to the optimum doping level has been insufficiently (or not at all) investigated. Much research has been done in the regions outside the optimal doping, be it underdoped or overdoped. I would like to deviate from the "mainstream" for a moment and ask whether these regions are really so relevant for the occurrence of superconductivity, or whether they simply serve to interfere with it - a thought which I am sure has been expressed by others and which would certainly lead (or had already led) to lively discussions with Karl-Alex Mueller.

description: Force fields uniquely assign interatomic forces for a given set of atomic coordinates. The underlying assumption is that electrons are in their quantum-mechanical ground state or in thermal equilibrium. However, there is an abundance of cases where this is unjustified because the system is only locally in equilibrium. In particular, the fractional charges of atoms, clusters, or solids tend to not only depend on atomic positions but also on how the system reached its state. For example, the charge of an isolated solid -- and thus the forces between atoms in that solid -- usually depends on the counterbody with which it has last formed contact. Similarly, the charge of an atom, resulting from the dissociation of a molecule, can differ for different solvents in which the dissociation took place. In this paper we demonstrate that such charge-transfer history effects can be accounted for by assigning discrete oxidation states to atoms. With our method, an atom can donate an integer charge to another, nearby atom to change its oxidation state as in a redox reaction. In addition to integer charges, atoms can exchange "partial charges" which are determined with the split charge equilibration method.

Modelling Grain Rotational Disruption by Radiative Torques and Extinction of Active Galactic Nuclei

description: Extinction curves observed toward individual Active Galactic Nuclei (AGN) usually show a steep rise toward far-ultraviolet (FUV) wavelengths and can be described by the Small Magellanic Cloud (SMC)-like dust model. This feature suggests the dominance of small dust grains of size $a \leq 0.1 μm$ in the local environment of AGN, but the origin of such small grains is unclear. In this paper, we aim to explain this observed feature by applying the RAdiative Torque Disruption (RATD) to model the extinction of AGN radiation from FUV to mid-infrared (MIR) wavelengths. We find that in the intense radiation field of AGN, large composite grains of size $a \geq 0.1 μm$ are significantly disrupted to smaller sizes by RATD up to $d_{\rm RATD} > 100$ pc in the polar direction and $d_{\rm RATD} \sim 10$ pc in the torus region. Consequently, optical-MIR extinction decreases, whereas FUV-near-ultraviolet (NUV) extinction increases, producing a steep far-UV rise extinction curve. The resulting total-to-selective visual extinction ratio thus significantly drops to $R_{\rm V} < 3.1$ with decreasing distances to AGN center due to the enhancement of small grains. The dependence of $R_{\rm V}$ with the efficiency of RATD will help us to study the dust properties in the AGN environment via photometric observations. In addition, we suggest that the combination of the strength between RATD and other dust destruction mechanisms which are responsible for destroying very small grains of $a \leq 0.05 μm$ is the key for explaining the dichotomy observed 'SMC' and 'gray' extinction curve toward many AGN.

description: As one of the most energetic and brightest events, gamma-ray bursts (GRBs) can be treated as a promising probe of the high-redshift universe. Similar to type Ia supernovae (SNe Ia), GRBs with same physical origin could be treated as standard candles. We select GRB samples with the same physical origin, which are divided into two groups. One group is consisted of 31 GRBs with a plateau phase feature of a constant luminosity followed by a decay index of about -2 in the X-ray afterglow light curves, and the other has 50 GRBs with a shallow decay phase in the optical light curves. For the selected GRB samples, we confirm that there is a tight correlation between the plateau luminosity $L_0$, the end time of plateau $t_b$ and the isotropic energy release $E_{γ,iso}$. We also find that the $L_0-t_b-E_{γ,iso}$ correlation is insensitive to the cosmological parameters and no valid limitations on the cosmological parameters can be obtained using this correlation. We explore a new three-parameter correlation $L_0$, $t_b$, and the spectral peak energy in the rest frame $E_{p,i}$ ($L_0-t_b-E_{p,i}$), and find that this correlation can be used as a standard candle to constrain the cosmological parameters. By employing the optical sample only, we find the constraints of $Ω_m = 0.697_{-0.278}^{+0.402}(1σ)$ for a flat $Λ$CDM model. For the non-flat $Λ$CDM model, the best-fitting results are $Ω_m = 0.713_{-0.278}^{+0.346}$, $Ω_Λ = 0.981_{-0.580}^{+0.379}(1σ)$. For the combination of the X-ray and optical smaples, we find $Ω_m = 0.313_{-0.125}^{+0.179}(1σ)$ for a flat $Λ$CDM model, and $Ω_m = 0.344_{-0.112}^{+0.176}$, $Ω_Λ = 0.770_{-0.416}^{+0.366}(1σ)$ for a non-flat $Λ$CDM model.

description: Propagation in quantum walks is revisited by showing that very general 1D discrete-time quantum walks with time- and space-dependent coefficients can be described, at the continuous limit, by Dirac fermions coupled to electromagnetic fields. Short-time propagation is also established for relativistic diffusions by presenting new numerical simulations of the Relativistic Ornstein-Uhlenbeck Process. A geometrical generalization of Fick's law is also obtained for this process. The results suggest that relativistic diffusions may be realistic models of decohering or random quantum walks. Links with general relativity and geometrical flows are also mentioned.

description: In rural regions around the world, 1.7 billion people rely on public taps, hand-pumps, protected wells, protected springs, and rainwater for clean drinking water. Up to the present, there has been little focus on how training programs in communities receiving the water points fit into the overall picture of sustainability. Many factors of sustainability such as financial management and operation, and governance of the water point are dependent on human skill, which are often first exposed to a community through training programs. To understand better how trainings affect the sustainability of water points, I sent surveys to personnel from NGOs who have worked as trainers in water development projects in Senegal, Malawi, Honduras, and India. I also conducted surveys and focus groups with NGO personnel and the community members who went through their trainings in three villages in Senegal. I then compared perspectives of trainers and community members using Grounded Theory, facilitated by using Nvivo 10. The results of all four countries' results from NGO personnel showed that the central themes found in responses were management, community, knowledge, NGO and community relations, and the trainer-learner relationship. Comparing the central themes of the trainers and learners in Senegal, the two groups' responses showed that mutually tied themes were knowledge, management, mechanical, and profits/finances. In order to improve training to make water points more sustainable, I recommend that NGOs consider how people trained will relate to the rest of the community, and furthermore, see how the trainings and information learned will function in the community after the NGO leaves the community.

description: A second Higgs doublet arises naturally as a parity partner of the standard model (SM) Higgs, once SM is extended to its left-right symmetric version (LRSM) to understand the origin of parity violation in weak interactions as well as to accommodate small neutrino masses via the seesaw mechanism. The flavor changing neutral Higgs (FCNH) effects in the minimal version of this model (LRSM), however, push the second Higgs mass to more than 15 TeV making it inaccessible at the LHC. Furthermore since the second Higgs mass is directly linked to the $W_R$ mass, discovery of a "low" mass $W_R$ ($M_{W_R}\leq 5-6$ TeV) at the LHC would require values for some Higgs self couplings larger than one. In this paper we present an extension of LRSM by adding a vector-like $SU(2)_R$ quark doublet which weakens the FCNH constraints allowing the second Higgs mass to be near or below TeV and a third neutral Higgs below 3 TeV for a $W_R$ mass below 5 TeV. It is then possible to search for these heavier Higgs bosons at the LHC, without conflicting with FCNH constraints. A right handed $W_R$ mass in the few TeV range is quite natural in this class of models without having to resort to large scalar coupling parameters. The CKM mixings are intimately linked to the vector-like quark mixings with the known quarks, which is the main reason why the constraints on the second Higgs mass is relaxed. We present a detailed theoretical and phenomenological analysis of this extended LR model and point out some tests as well as its potential for discovery of a second Higgs at the LHC. Two additional features of the model are: (i) a 5/3 charged quark and (ii) a fermionic top partner with masses in the TeV range.

description: High-quality light curves from space missions have opened up a new window on the rotational and pulsational properties of magnetic chemically peculiar (mCP) stars and have fuelled asteroseismic studies. They allow the internal effects of surface magnetic fields to be probed and numerous astrophysical parameters to be derived with great precision. We present an investigation of the photometric variability of a sample of 1002 mCP stars discovered in the LAMOST archival spectra with the aims of measuring their rotational periods and identifying interesting objects for follow-up studies. TESS photometry was available for 782 mCP stars and was analysed using a Fourier two-term frequency fit to determine the stars' rotational periods. The rotational signal was then subtracted from the light curve to identify non-rotational variability. A pixel-level blending analysis was performed to check whether the variability originates in the target star or a nearby blended neighbour. We investigated correlations between the rotational periods, fractional age on the main sequence, mass, and several other observables. We present rotational periods and period estimates for 720 mCP stars. In addition, we identified four eclipsing binary systems that likely host an mCP star, as well as 25 stars with additional signals consistent with pulsation (12 stars with frequencies above 10 d$^{-1}$ and 13 stars with frequencies below 10 $^{-1}$). We find that more evolved stars have longer rotation periods, in agreement with the assumption of the conservation of angular momentum during main-sequence evolution. With our work, we increase the sample size of mCP stars with known rotation periods and identify prime candidates for detailed follow-up studies. This enables two paths towards future investigations: population studies of even larger samples of mCP stars and the detailed characterisation of high-value targets.

description: Ramsey proved that for every positive integer $n$, every sufficiently large graph contains an induced $K_n$ or $\overline{K}_n$. Among the many extensions of Ramsey's Theorem there is an analogue for connected graphs: for every positive integer $n$, every sufficiently large connected graph contains an induced $K_n$, $K_{1,n}$, or $P_n$. In this paper, we establish an analogue for 2-connected graphs. In particular, we prove that for every integer exceeding two, every sufficiently large 2-connected graph contains one of the following as an induced subgraph: $K_n$, a subdivision of $K_{2,n}$, a subdivision of $K_{2,n}$ with an edge between the two vertices of degree $n$, and a well-defined structure similar to a ladder.

description: For a long time now, archaeological research has not been conducted by individual researchers who come up with brilliant theories in their study rooms and investigate them by themselves and on their own terms. It is a fact that no serious scientific research can be conducted without substantial and extensive collaboration. The internet facilitated a significant change in work processes, something we have been able to experience vividly in the last two years. Since it was intended from the start as a tool to enable scientific exchange, it is all the more astonishing that collaborative work via the internet did not develop further from back-and-forth emailing of text manuscripts for such a long time. By now there are a variety of different systems and solutions: communication via Slack or Signal, co-writing via Google Docs or Overleaf, data co-creation in online database systems, Open Science Framework or Wikidata, as well as code co-development via GitHub or GitLab. Streamlined and meaningful collaborative work on research questions is possible nowadays, not just with textual products. Especially in the case of analytical archaeology, where data analysis is a focal point, scientific scripting languages shine. There are several research tools and little minions that combine textuality with machine executability to facilitate a collaborative process of thought and analysis...
SO and SiS Emission Tracing an Embedded Planet and Compact $^{12}$CO and $^{13}$CO Counterparts in the HD 169142 Disk

description: Planets form in dusty, gas-rich disks around young stars, while at the same time, the planet formation process alters the physical and chemical structure of the disk itself. Embedded planets will locally heat the disk and sublimate volatile-rich ices, or in extreme cases, result in shocks that sputter heavy atoms such as Si from dust grains. This should cause chemical asymmetries detectable in molecular gas observations. Using high-angular-resolution ALMA archival data of the HD 169142 disk, we identify compact SO J=8$_8$-7$_7$ and SiS J=19-18 emission coincident with the position of a ${\sim}$2 M$_{\rm{Jup}}$ planet seen as a localized, Keplerian NIR feature within a gas-depleted, annular dust gap at ${\approx}$38 au. The SiS emission is located along an azimuthal arc and has a similar morphology as a known $^{12}$CO kinematic excess. This is the first tentative detection of SiS emission in a protoplanetary disk and suggests that the planet is driving sufficiently strong shocks to produce gas-phase SiS. We also report the discovery of compact $^{12}$CO and $^{13}$CO J=3-2 emission coincident with the planet location. Taken together, a planet-driven outflow provides the best explanation for the properties of the observed chemical asymmetries. We also resolve a bright, azimuthally-asymmetric SO ring at ${\approx}$24 au. While most of this SO emission originates from ice sublimation, its asymmetric distribution implies azimuthal temperature variations driven by a misaligned inner disk or planet-disk interactions. Overall, the HD 169142 disk shows several distinct chemical signatures related to giant planet formation and presents a powerful template for future searches of planet-related chemical asymmetries in protoplanetary disks.

description: McGill Food and Dining Services (MFDS) have, over the past three years, progressed as a leader in sustainable practices at McGill University. Increased expectations for sustainable management have pushed Executive Chef Oliver deVolpi to assess energy efficiency at the Bishop Mountain Hall (BMH) and Royal Victoria College (RVC) cafeterias. This project aims to determine which technical and behavioural modifications should be made in the Royal Victoria College (RVC) and Bishop Mountain Hall (BMH) cafeterias in order to increase energy efficiency. Two key aspects determining energy consumption were addressed: the required energy input of the appliances and the frequency and manner of appliance usage. The technical approach assessed the sustainability of energy sources, including natural gas, electricity, and steam. The behavioural approach identified necessary improvements in mealtimes, the operation and availability of appliances, and staff practices. Using this data and appliance specification data, priority lists of suggested appliance replacements were made.
