description: We study a planar model of a non-relativistic electron in periodic magnetic and electric fields that produce a 1D crystal for two spin components separated by a half-period spacing. We fit the fields to create a self-isospectral pair of finite-gap associated Lame equations shifted for a half-period, and show that the system obtained is characterized by a new type of supersymmetry. It is a special nonlinear supersymmetry generated by three commuting integrals of motion, related to the parity-odd operator of the associated Lax pair, that coherently reflects the band structure and all its peculiarities. In the infinite period limit it provides an unusual picture of supersymmetry breaking.

description: We present an active cloaking method for the parabolic heat (and mass or light diffusion) equation that can hide both objects and sources. By active we mean that it relies on designing monopole and dipole heat source distributions on the boundary of the region to be cloaked. The same technique can be used to make a source or an object look like a different one to an observer outside the cloaked region, from the perspective of thermal measurements. Our results assume a homogeneous isotropic bulk medium and require knowledge of the source to cloak or mimic, but are in most cases independent of the object to cloak.

description: As the public seeks greater accountability and transparency from machine learning algorithms, the research literature on methods to explain algorithms and their outputs has rapidly expanded. Feature importance methods form a popular class of explanation methods. In this paper, we apply the lens of feminist epistemology to recent feature importance research. We investigate what epistemic values are implicitly embedded in feature importance methods and how or whether they are in conflict with feminist epistemology. We offer some suggestions on how to conduct research on explanations that respects feminist epistemic values, taking into account the importance of social context, the epistemic privileges of subjugated knowers, and adopting more interactional ways of knowing.

The $λ$-point anomaly in view of the seven-loop Hypergeometric resummation for the critical exponent $ν$ of the $O(2)$ $ϕ^4$ model

description: In this work, we use a specific parameterization of the hypergeometric approximants ( the one by Mera et.al in Phys. Rev. Let. 115, 143001 (2015)) to approximate the seven-loop critical exponent $ν$ for the $O(2)$-symmetric $ϕ^4$ model. Our prediction gives the result $ν=0.6711(7)$ which is compatible with the value $ν=0.6709(1)$ from the famous experiment carried on the space shuttle Columbia. On the other hand, our result is also compatible with recent precise theoretical predictions that are excluding the experimental result. These theoretical results include non-perturbative renormalization group calculations ( $ν=0.6716(6)$), the most precise result from Monte Carlo simulations ($ν=0.67169(7)$) as well as the recent conformal bootstrap calculations ($ν=0.67175(10)$). Although our result is compatible with experiment, the plot of renormalization group result versus the number of loops suggests that higher orders are expected to add significantly to accuracy and precision of the $ν$ exponent in a way that may favor the theoretical predictions.

description: In the solar convection zone, rotation couples with intensely turbulent convection to build global-scale flows of differential rotation and meridional circulation. Our sun must have rotated more rapidly in its past, as is suggested by observations of many rapidly rotating young solar-type stars. Here we explore the effects of more rapid rotation on the patterns of convection in such stars and the global-scale flows which are self-consistently established. The convection in these systems is richly time dependent and in our most rapidly rotating suns a striking pattern of spatially localized convection emerges. Convection near the equator in these systems is dominated by one or two patches of locally enhanced convection, with nearly quiescent streaming flow in between at the highest rotation rates. These active nests of convection maintain a strong differential rotation despite their small size. The structure of differential rotation is similar in all of our more rapidly rotating suns, with fast equators and slower poles. We find that the total shear in differential rotation, as measured by latitudinal angular velocity contrast, Delta_Omega, increases with more rapid rotation while the relative shear, Delta_Omega/Omega, decreases. In contrast, at more rapid rotation the meridional circulations decrease in both energy and peak velocities and break into multiple cells of circulation in both radius and latitude.

Year: 2019

description: Obtaining valid SNV- and indel calling results from next-generation sequencing data is still an important issue in the field of bioinformatics. In close collaboration with medical and biological experts, we developed appreci8 -- A Pipeline for PREcise variant Calling Integrating 8 tools, which outperforms any alternative approach.

Here we present the appreci8R, an R-version of our appreci8-algorithm. The appreci8R relies on the same rule-based system for variant calling as appreci8. Functions for the standard analysis steps as well as a shiny GUI are provided. Different from classical appreci8, the user may change any analysis parameter, including the artifact- and polymorphism score. Furthermore, any other combination of variant calling tools, including additional tools, is supported. Checkpoints are provided, allowing to re-start analysis from intermediate results.

Analyzing two well-characterized Illumina datasets, we observe that run-time and performance of the appreci8R are comparable to classical appreci8. Investigating the influence of a single updated tool, here GATK-3.3 vs GATK-4, we observe 5-23\% more variants -- true as well as false positives -- in the GATK output. However, the final appreci8R results remain stable.

Concluding, the appreci8R represents a powerful tool for variant calling, providing more liberties at equal performance compared to classical appreci8.

Focus Issue on Selected Papers of Invited Speakers to IMLB 2020

description: Lithium-air batteries are a promising energy storage technology for transport applications, given their exceptionally high energy density. However, their development is significantly hampered by high overpotentials, which lead to poor efficiency and short lifetimes. Redox mediators provide a solution to this problem by shuttling electrons from the electrode to the active species at just above the redox potential of the mediator. Thus, knowing the redox potential and having the ability to tune it are critical to electrochemical performance. We focus on LiI as a model mediator—given its additional role in controlling LiOH vs Li2O2 chemistry—and use cyclic voltammetry (CV), NMR, UV/Vis spectrometry, and molecular dynamics (MD) simulations to monitor the effects of electrolyte composition on solvation. Li+ and I– solvation in common Li-air solvents, the electrochemical implications, and the applicability of each technique to probe the nature of the solvation shell and its effect on the electrochemical properties are explored. Starting with a simple thermodynamic model, we then used UV/Vis spectrometry to probe I– solvation, 1H NMR spectroscopy to study water solvation and 31P of the probe molecule triethylphosphine oxide (TEPO) to explore Li+ solvation; we find that no single descriptor can provide an accurate description of the solvation environment. Instead, we use all these methods in combination with the MD results to help rationalise the CV data. We find that the I– solvation improves significantly in tetraglyme (G4), with increasing salt and water concentration, but minimal effects on changing salt/water concentrations are seen in DMSO. In contrast, increasing salt concentration increases the Li+ activity in DMSO but not in G4. Furthermore, a simple model considering the equilibria between the different species was used to explain the 1H NMR data.
Downsizing by Shutdown in Red Galaxies

description: We address the origin of the `downsizing' of elliptical galaxies, according to which the stars in more massive galaxies formed earlier and over a shorter period than those in less massive galaxies. We show that this could be the natural result of a shutdown of star formation in dark matter haloes above a critical mass of 10^12MSun. This is demonstrated using a semianalytic simulation of galaxy formation within the standard hierarchical scenario of structure formation. The assumed threshold mass is motivated by the prediction of stable shock heating above this mass and the finding that such a shutdown reproduces the observed distribution of galaxies in luminosity and colour.The shutdown at a critical halo mass introduces a characteristic stellar mass for the transition of galaxies into the `red sequence' of the galaxy colour-magnitude diagram. Central galaxies of haloes that are more massive today have reached this mass earlier and can therefore grow further along the red sequence by dry mergers, ending up more massive and containing older stars. Small galaxies formed in haloes below the critical mass can shutdown late, when they fall into haloes above the critical mass and become satellites. While our semianalytic simulation that incorporates an explicit shutdown reproduces downsizing as inferred from the stellar ages of ellipticals, we explain why it is much harder to detect downsizing using the mass functions of different galaxy types.

description: As the most extreme members of the rapidly evolving faint blue galaxy population at intermediate redshift, the compact narrow emission line galaxies (CNELGs) are intrinsically luminous (-22 < M_B < -18) with narrow emission linewidths (30 < σ< 125 km/s). Their nature is heavily debated: they may be low-mass starbursting galaxies that will fade to present-day dwarf galaxies or bursts of star formation temporarily dominating the flux of more massive galaxies, possibly related to in situ bulge formation or the formation of cores of galaxies. We present deep, high-quality (~0.6 - 0.8 arcsec) images with CFHT of 27 CNELGs. One galaxy shows clear evidence for a tidal tail; the others are not unambiguously embedded in galactic disks. Approximately 55% of the CNELGS have sizes consistent with local dwarfs of small-to-intermediate sizes, while 45% have sizes consistent with large dwarfs or disks galaxies. At least 4 CNELGs cannot harbor substantial underlying disk material; they are low-luminosity galaxies at the present epoch (M_B > -18). Conversely, 15 are not blue enough to fade to low-luminosity dwarfs (M_B > -15.2). The majority of the CNELGs are consistent with progenitors of intermediate-luminosity dwarfs and low-luminosity spiral galaxies with small disks. CNELGs are a heterogeneous progenitor population with significant fractions (up to 44%) capable of fading into today's faint dwarfs (M_B > -15.2), while 15 to 85% may only experience an apparently extremely compact CNELG phase at intermediate redshift but remain more luminous galaxies at the present epoch.

We show that the principal subspaces possess the quantum vertex algebra structure, which turns to the usual vertex algebra structure of the principal subspaces of generalized Verma and standard modules at the classical limit. Moreover, we find their topological quasi-particle bases which correspond to the sum sides of certain Rogers-Ramanujan-type identities.

ESAME DELLA CONVENIENZA O MENO DI COSTRUIRE IL CHOKE-COIL DI PROTEZIONE DELLA DINAMO DI ECCITAZIONE CONTINUA-ALTERNATA DI UN SINCROTRONE PARTE IN LAMIERINI E PARTE IN FERRO MASSICCIO

description: Le dimensioni della bobina di protezione della dinamo di cui alla relazione n.5, parte IF, sono determinate, oltre che dalla necessita' di realizzare una induttanza di un dato valore, anche dal fatto che e' necessario mantenere un valore di B (campo magnetico) inferiore alla saturazione (NS = IS/B ove L = valore dell'induttanza; I = valore della corrente continua, B = valore massimo permesso nel ferro; N = numero di spire; S = sezione del ferro. Se B potesse aumentare, NS, che ci fornisce un indice delle dimensioni della bobina, potrebbe diminuire, e con esso il prezzo della bobina. Il prof. Salvini faceva notare come, essendo che la saturazione del ferro (lamierini) e' quasi esclusivamente provocata dalla corrente continua, si dovrebbe cercare di smistare il flusso dovuto alla corrente continua in un materiale magnetico massiccio di minor costo, e di far si che il laminato servisse soprattutto ad accogliere il flusso alternato. Egli proponeva un circuito avente lo schema di fig. 1 e mi dava l'incarico di vedere se con tale circuito era possibile risparmiare nel costo del ferro.
Universal regularization for string field theory

description: We find an analytical regularization for string field theory calculations. This regularization has a simple geometric meaning on the worldsheet, and is therefore universal as level truncation. However, our regularization has the added advantage of being analytical. We illustrate how to apply our regularization to both the discrete and continuous basis for the scalar field and for the bosonized ghost field, both for numerical and analytical calculations. We reexamine the inner products of wedge states, which are known to differ from unity in the oscillator representation in contrast to the expectation from level truncation. These inner products describe also the descent relations of string vertices. The results of applying our regularization strongly suggest that these inner products indeed equal unity. We also revisit Schnabl's algebra and show that the unwanted constant vanishes when using our regularization even in the oscillator representation.

description: Microbial communities pervade the soil, diversifying into different soil horizons and influencing plant performance both indirectly and directly. Advances in cultivation techniques and metagenomic analyses have allowed for the profiling of plant growth-promoting bacteria (PGPB), contributing to an enhanced understanding of plant and microbial interactions. However, the presence and effects of PGPB in soil microbial communities of regional chaparral ecosystem affected by wildfires require more research. To assess the presence of PGP-containing bacteria and the compositional differences between burned and unburned microbial communities and their functional profiles, burned and unburned soil microbial communities of Skirball were analyzed for specific PGP properties, including the ability to fix nitrogen, form siderophores, and solubilize phosphate. Metagenomic analysis including phylogenetic tree construction, Rancapa, and STAMP analyses were used to infer compositional identity of soil samples as well as the differences between burned and unburned soils. Cultivation dependent analyses revealed the presence of PGP microorganisms in a burned soil sample, many of which expressed more than one PGP property. However, metagenomic analyses of the compositional and functional differences between burned and unburned samples revealed few significant differences in the diversity and abundances of certain PGP microorganisms or pathways.

description: Measurements of the 21cm line emission by residual cosmic hydrogen after reionization can be used to trace the power spectrum of density perturbations through a significant fraction of the observable volume of the Universe. We show that a dedicated 21cm observatory coule probe a number of independent modes that is two orders of magnitude larger than currently available, and enable a cosmic-variance limited detection of the signature of a neutrino mass ~0.05eV. The evolution of the linear growth factor with redshift could also constrain exotic theories of gravity or dark energy to an unprecedented precision.

Adaptive design
safety
tolerability
efficacy

description: Pulmonary arterial hypertension is an unmet clinical need. Imatinib, a tyrosine kinase inhibitor, 200 to 400 mg daily reduces pulmonary artery pressure and increases functional capacity in this patient group, but is generally poorly tolerated at the higher dose. We have designed an open-label, single-arm clinical study to investigate whether there is a tolerated dose of imatinib that can be better targeted to patients who will benefit. The study consists of two parts. Part 1 seeks to identify the best tolerated dose of Imatinib in the range from 100 and up to 400 mg using a Bayesian Continuous Reassessment Method. Part 2 will measure efficacy after 24 weeks treatment with the best tolerated dose using a Simon's two-stage design. The primary efficacy endpoint is a binary variable. For patients with a baseline pulmonary vascular resistance (PVR) >1000 dynes · s · cm-5, success is defined by an absolute reduction in PVR of ≥300 dynes · s · cm-5 at 24 weeks. For patients with a baseline PVR ≤1000 dynes · s · cm-5, success is a 30% reduction in PVR at 24 weeks. PVR will also be evaluated as a continuous variable by genotype as an exploratory analysis. Evaluating the response to that dose by genotype may inform a prospective biomarker-driven study.

description: We have used extensive libraries of model and empirical galaxy spectra (assembled respectively from the population synthesis code of Bruzual and Charlot and the fourth data release of the Sloan Digital Sky Survey) to interpret some puzzling features seen in the spectra of high redshift star-forming galaxies. We show that a stellar He II 1640 emission line, produced in the expanding atmospheres of Of and Wolf-Rayet stars, should be detectable with an equivalent width of 0.5-1.5AA in the integrated spectra of star-forming galaxies, provided the metallicity is greater than about half solar. Our models reproduce the strength of the He II 1640 line measured in the spectra of Lyman break galaxies for established values of their metallicities. With better empirical calibrations in local galaxies, this spectral feature has the potential of becoming a useful diagnostic of massive star winds at high, as well as low, redshifts. We also uncover a relationship in SDSS galaxies between their location in the [O III]/Hb vs. [N II]/Ha diagnostic diagram (the BPT diagram) and their excess specific star formation rate relative to galaxies of similar mass. We infer that an elevated ionisation parameter U is at the root of this effect, and propose that this is also the cause of the offset of high redshift star-forming galaxies in the BPT diagram compared to local ones. We further speculate that higher electron densities and escape fractions of hydrogen ionising photons may be the factors responsible for the systematically higher values of U in the H II regions of high redshift galaxies. The impact of such differences on abundance determinations from strong nebular lines are considered and found to be relatively minor.

description: We apply Bayesian inference methods to a suite of distinct compartmental models of generalised SEIR type, in which diagnosis and quarantine are included via extra compartments. We investigate the evidence for a change in lethality of COVID-19 in late autumn 2020 in the UK, using age-structured, weekly national aggregate data for cases and mortalities. Models that allow a (step-like or graded) change in infection fatality rate (IFR) have consistently higher model evidence than those without. Moreover, they all infer a close to two-fold increase in IFR. This value lies well above most previously available estimates. However, the same models consistently infer that, most probably, the increase in IFR preceded the time window during which variant B.1.1.7 (alpha) became the dominant strain in the UK. Therefore, according to our models, the caseload and mortality data do not offer unequivocal evidence for higher lethality of a new variant. We compare these results for the UK with similar models for Germany and France, which also show increases in inferred IFR during the same period, despite the even later arrival of new variants in those countries. We argue that while the new variant(s) may be one contributing cause of a large increase in IFR in the UK in autumn 2020, other factors, such as seasonality, or pressure on health services, are likely to also have contributed.

Two such analyses, addressing inclusive $ϕ$ production with $ϕ\toτ^+τ^-$, and associated $ϕb(\bar{b})$ production with $ϕ\to b\bar{b}$ are reported here. No excess of events above the background expectation has been observed in any of these analyses. The results are combined to set constraints on the MSSM parameter space.

description: Shape correspondence is a fundamental problem in computer graphics and vision, with applications in various problems including animation, texture mapping, robotic vision, medical imaging, archaeology and many more. In settings where the shapes are allowed to undergo non-rigid deformations and only partial views are available, the problem becomes very challenging. To this end, we present a non-rigid multi-part shape matching algorithm. We assume to be given a reference shape and its multiple parts undergoing a non-rigid deformation. Each of these query parts can be additionally contaminated by clutter, may overlap with other parts, and there might be missing parts or redundant ones. Our method simultaneously solves for the segmentation of the reference model, and for a dense correspondence to (subsets of) the parts. Experimental results on synthetic as well as real scans demonstrate the effectiveness of our method in dealing with this challenging matching scenario.

description: In this paper, combining the ideas of exponential integrators and discrete gradients, we propose and analyze a new structure-preserving exponential scheme for the conservative or dissipative system $\dot{y} = Q(M y + \nabla U (y))$, where $Q$ is a $d\times d$ skew-symmetric or negative semidefinite real matrix, $M$ is a $d\times d$ symmetric real matrix, and $U : \mathbb{R}^d\rightarrow\mathbb{R}$ is a differentiable function. We present two properties of the new scheme. The paper is accompanied by numerical results that demonstrate the remarkable superiority of our new scheme in comparison with other structure-preserving schemes in the scientific literature.

description: Although synthetic test problems are widely used for the performance assessment of evolutionary multi-objective optimization algorithms, they are likely to include unrealistic properties which may lead to overestimation/underestimation. To address this issue, we present a multi-objective optimization problem suite consisting of 16 bound-constrained real-world problems. The problem suite includes various problems in terms of the number of objectives, the shape of the Pareto front, and the type of design variables. 4 out of the 16 problems are multi-objective mixed-integer optimization problems. We provide Java, C, and Matlab source codes of the 16 problems so that they are available in an off-the-shelf manner. We examine an approximated Pareto front of each test problem. We also analyze the performance of six representative evolutionary multi-objective optimization algorithms on the 16 problems. In addition to the 16 problems, we present 8 constrained multi-objective real-world problems.

description: The text presented here is a fictional dialogue between giants of mathematics aimed at provoking reflection.It is not a new conjecture, hypothesis, or theory, but rather the acknowledgment of a mathematical fact that becomes obvious and self-evident once pointed out.

Only the prime numbers up to x/2 are necessary and sufficient to compose or structure all composite numbers up to x, with x>3.This is undeniable. It is pure arithmetic that reveals the duality of primes.

The dramatized text plays with the possibility that Gauss, who proposed π(x) as a teenager, already knew this but considered it too trivial to warrant any comment.

However, the duality of primes naturally provokes oscillations around x/2, and, as if by magic—no, by logic—immediately collapses the RH when this duality is understood.By Riemann’s own explicit formula, it becomes evident that any zero out of place would violate this primal duality, which is absurd.

But simple truths like this are not easy to accept. They are often ignored, rejected, and ridiculed.Look at what happened with the discovery of the square root of 2.

I am neither a mathematician nor a physicist, just an economist with some expertise in data science who has seen too much.The dramatized text seemed to me the best way to communicate this observation to a broader audience.The play is accompanied by a more formal and didactic text with all the computational evidence presented (Zenodo DOI), as well as a link to an open GitHub repository (GitHub Link) for those who wish to replicate the observations.

Finally, an open request:If you listen to the primes and what they have to say, help me spread this truth throughout the academic community.Truth, once revealed, cannot be ignored.I kindly ask for your collaboration and endorsement to help publish the didactic text on arXiv.

The primes thank you!

Taurid Complex Smoking Gun: Detection of Cometary Activity

description: Using the Secular Light Curve (SLC) formalism (Ferrín, 2010), we have catalogued 88 probable members of the Taurid Complex (TC). 51 of them have useful SLCs and 34 of these (67%) exhibit cometary activity. This high percentage of active asteroids gives support to the hypothesis of a catastrophe that took place during the Upper Paleolithic (Clube and Napier, 1984), when a large short-period comet, arriving in the inner Solar System from the Kuiper Belt, experienced, starting from 20 thousand years ago, a series of fragmentations that produced the present 2P/Encke comet, together with a large number of other members of the TC. The fragmentation of the progenitor body was facilitated by its heterogeneous structure (very similar to a rubble pile) and this also explains the current coexistence in the complex of fragments of different composition and origin. We have found that (2212) Hephaistos and 169P/NEAT are active and members of the TC with their own sub-group. Other components of the complex are groups of meteoroids, that often give rise to meteor showers when they enter the terrestrial atmosphere, and very probably also the two small asteroids that in 1908 and 2013 exploded in the terrestrial atmosphere over Tunguska and Chelyabinsk, respectively. What we see today of the TC are the remnants of a very varied and numerous complex of objects, characterized by an intense past of collisions with the Earth which may continue to represent a danger for our planet.

description: Abstract We study L  q -spectra of planar self-affine measures generated by diagonal matrices. We introduce a new technique for constructing and understanding examples based on combinatorial estimates for the exponential growth of certain split binomial sums. Using this approach we disprove a theorem of Falconer and Miao from 2007 and a conjecture of Miao from 2008 concerning a closed form expression for the generalised dimensions of generic self-affine measures. We also answer a question of Fraser from 2016 in the negative by proving that a certain natural closed form expression does not generally give the L  q -spectrum. As a further application we provide examples of self-affine measures whose L  q -spectra exhibit new types of phase transitions. Finally, we provide new non-trivial closed form bounds for the L  q -spectra, which in certain cases yield sharp results.
REEEM-D6.5_Technical Documentation - Pathways Database
Creators: name: REEEM Project
Publisher: name: Zenodo
Year: 2019

description: Project manual: A flexible open-source and SQL-based Pathways Database will be set-up to service all models. It will be accessible through an interface on the project Web Platform. Existing databases within the Consortium will initially serve to populate the database, enabling open access as far as possible. Data gaps will be identified and filled to refine the models. The database will be updated to include additional technologies, demand categories, emission factors, etc. Additional data will be accessed through a range of public and private sources as well as drawing on data gathered for the case studies. Transparent data processing scripts and stand-alone tools will be developed to facilitate the communication between the various models used in REEEM, and to process basic to higher level datasets. Main challenges and tasks: In this project, a large group of modelling teams from different institutes are developing and using different software with different programming languages and modelling paradigms. This results in a large variety of data structures. Thus, the project database has to meet different requirements. Besides complying with basic data security and access regulations as described in the Data Management Plan (D8.2), the structure must be flexible and database usage should be as automated as possible. In an integrated assessment model, data from different fields are used and created. This leads to challenges in the data classification and categorisation which were solved developing and implementing a flexible tagging system. Besides the technical aspects, the legal aspects were considered as well. The project aims at publishing the data sets under open licenses.
Performance under pressure: the impact of coercive authority upon consent to treatment for sex offenders
Creators: name: Rigg, Jeremy
Publisher: name: University of British Columbia

description: This thesis is concerned with the correctional treatment process for sex offenders, and the problems that criminal justice system authority poses for treatment settings. A particular focus is whether inmate participation in treatment programs is voluntary or coerced, given the link between programs and prospects of release. In examining this question, the author considers the results of an empirical project in which a group of inmates were interviewed about their perceptions of the correctional treatment process. Background to this project includes discussion of the doctrine of informed consent and respect for autonomy as its underlying rationale; discussion of the concepts of coercion and voluntariness; and examination of the development of rehabilitative ideals. A conclusion drawn from the discussion is that the presence of coercive authority may impact adversely upon correctional treatment efforts. Coercive authority creates difficulties in relation to the voluntariness of inmates' consent, the confidentiality of the treatment relationship, and the professional autonomy of the clinician. These problems in turn raise questions as to whether correctional programs retain the character of treatment, or are more properly considered as part of punishment, or as tools of social control. However, coercive authority is a necessary presence if correctional services are to work towards the goal of protection of society. The central question to be addressed therefore is whether the prospects of release can be used to motivate inmates for treatment in a way that is consistent with the requirement of voluntary consent to treatment. The results of the empirical project suggest that for the majority of inmates, the link between treatment and release is not coercive. However, a number of inmates did indicate they felt coerced into treatment programs. Reforms may thus be necessary to avoid coercive authority resulting in coerced treatment. In discussing these results, the author considers a number of directions for reform, including the introduction of an operational presumption of coerced referrals to treatment, which would place greater emphasis on clinicians' obligations to secure voluntary consent.

description: Bacteriophages are efficient and specific in killing bacteria, and therefore are increasingly being studied to better understand phage-bacteria interactions. However, phages can also spread antibiotic resistance and toxic genes to beneficial bacteria through Horizontal Gene Transfer. Therefore, if prevention of phage adsorption to host bacteria is studied, then these negative consequences could be prevented. Phage Phalcolm, a Bacillus subtilis-infecting phage and phage Helpful, a Mycobacterium smegmatis-infecting phage, were both purified through enriched isolation. B. subtilis was chosen as the host bacterium because of its prevalence in the gastrointestinal tract; M. smegmatis was chosen because of its non-pathogenicity and shared homology to M. arupense, a human commensal bacteria. With B. subtilis as the host, standard plaque assays were used to reveal how certain environmental factors like temperature, salt additives, and acidity affect adsorption. While temperature was changed during incubation, acidity was altered in both the soft agar and the Lysogeny Broth (LB) plates, and salts were added to the adsorption tubes. However, no statistically significant results regarding Phalcolm’s ability to adsorb were observed when the aforementioned variables were changed. Meanwhile, Helpful’s 89 protein-coding genes were annotated using Phamerator, Starterator, NCBI and PhagesDB BLAST, and HHPRED, with a particular focus on any tail-associated proteins, which are known to be primary machinery for adsorption. While the experiments with phage Phalcolm proved insignificant, phage Helpful revealed structures of many tail proteins, which could potentially be targeted to prevent phage interaction with host bacteria and, consequently, adsorption.
