description: We consider the stationary solutions for a class of Schrodinger equations with a N-well potential and a nonlinear perturbation. By means of semiclassical techniques we prove that the dominant term of the ground state solutions is described by a N-dimensional Hamiltonian system, where the coupling term among the coordinates is a tridiagonal Toeplitz matrix. In particular we consider the case of N=4 wells, where we show the occurrence of spontaneous symmetry-breaking bifurcation effect. In particular, in the limit of large focusing nonlinearity we prove that the ground state stationary solutions consist of N wavefunctions localized on a single well.

description: Needles are a mainstay of modern healthcare, being used for drug delivery, biosampling, application of wearable technology, and measurement of biopotentials. Unfortunately, the use of needles comes with significant drawbacks, most importantly pain and anxiety associated with their use. Needle-phobia impacts nearly 60% of the American population and in severe cases will lead to avoidance of medical care and mismanagement of chronic conditions such as diabetes. Microneedles enable biosensing, drug administration, and other needle-functions, using small microprojections less than 1 mm in length. These tiny structures pierce the outer layers of the skin without reaching the deeper nervous tissues, rendering them effectively painless. Microneedles stand to alleviate significant mental burden on patients, economic burden on the healthcare system through avoidance of care, and deliver effective care to rural and remote populations. These advantages in mind, microneedle fabrication to-date has typically required either the use of expensive and low-throughput cleanroom microfabrication technologies, or bulkier commercial systems such as laser cutters and 3D printers which sacrifice microneedle efficacy for cost and material properties. There is presently no mass manufacturing ready, low-cost, scalable, cleanroom free strategy for making microneedles that are sharp, painless, and biosafe. This thesis describes the development of a novel fabrication process for solid metallic microneedles using an adapted electronics industry process known as wirebonding. Using this process, a fabrication protocol was developed to create a rapid manufacturing platform for low-cost, less than $2 per microneedle array, with high regularity (tip radii on order of ~10s of nm, geometry control on the order of ~10s of micrometers). The platform technology was evaluated to assess their insertion efficacy, drug delivery capabilities, and use as a biosensing technology. The fabrication method shown in this work is a novel, scalable technique for the development of high-density pain-free solid metal microneedle arrays, with ~1N array insertion forces, to be used to address the health and wellbeing of patients suffering from needle-phobia and chronic conditions.

description: We present results on the chiral and deconfinement properties of the QCD transition at finite temperature. Calculations are performed with 2+1 flavors of quarks using the p4, asqtad and HISQ/tree actions. Lattices with temporal extent N_tau=6, 8 and 12 are used to understand and control discretization errors and to reliably extrapolate estimates obtained at finite lattice spacings to the continuum limit. The chiral transition temperature is defined in terms of the phase transition in a theory with two massless flavors and analyzed using O(N) scaling fits to the chiral condensate and susceptibility. We find consistent estimates from the HISQ/tree and asqtad actions and our main result is T_c=154 +/- 9 MeV.

description: We present a clustering analysis of Luminous Red Galaxies in SDSS Stripe 82. We study the angular 2-point correlation function, of 130,000 LRG candidates via colour-cut selections in izK with the K band coverage coming from UKIDSS LAS. We have used the cross-correlation technique of Newman (2008) to establish the LRG redshift distribution. Cross-correlating with SDSS QSOs, MegaZ-LRGs and DEEP2 galaxies implies an average LRG redshift of z~1 with space density, n_g~3.2 +/-0.16 x10^-4 h^3 Mpc^-3. For theta<10', w(theta) significantly deviates from a single power-law. A double power-law with a break at r_b~2.4 h^-1 Mpc fits the data better, with best-fit scale length, r_0,1=7.63+/-0.27 h^-1Mpc and slope gamma_1=2.01 +/-0.02 at small scales and r_0,2=9.92 +/-0.40 h^-1 Mpc and gamma_2=1.64 +/-0.04 at large scales. Due to the flat slope at large scales, we find that a standard LambdaCDM linear model is accepted only at 2-3sigma, with the best-fit bias factor, b=2.74+/-0.07. We also fitted HOD models and estimate an effective halo mass of M_eff=3.3 +/-0.6x10^13 h^-1 M_sun. But at large scales, the current HOD models did not help explain the power excess in the clustering signal. We then compare the w(theta) results to those of Sawangwit et al. (2011) from 3 samples of LRGs at lower redshifts to measure clustering evolution. We find that a long-lived model may be a poorer fit than at lower redshifts, although this assumes that the Stripe 82 LRGs are luminosity-matched to the AAOmega LRGs. We find stronger evidence for evolution in the form of the z~1 LRG correlation function, with the above flat 2-halo slope maintaining to r>50 h^-1 Mpc. Applying the cross-correlation test of Ross et al. (2011), we find little evidence that the result is due to systematics. Otherwise it may provide evidence for primordial non-Gaussianity in the matter distribution, with f^local_NL=90+/-30.[Abridged]

Structural and functional characterization of the surface layer of Caulobacter crescentus
Creators: name: Mertens, Jan
Publisher: name: University of British Columbia
Year: 2012

description: Proteinaceous surface layers (S-layers) have been identified in hundreds of different species belonging to all major phylogenetic groups of Bacteria and most Archaea and form a geometrically arranged paracrystalline lattice. Despite their wide abundance, few structural and functional studies have been performed on S-layers. Obtaining high-resolution structural models has been hampered by the aggregation properties of S-layers, whereas only a few functions have been identified. This thesis focuses on the structure and the function of the hexagonal S-layer of the environmental bacterium Caulobacter crescentus. In the first part of my thesis, an array of new methods was devised and tested to stabilize the S-layer protein (RsaA). Protein concentrations of an N-terminally truncated protein (RsaAΔ0-222) could be increased up to 7 mg/mL while maintaining the protein in the monomeric form. Stable protein samples were found to crystallize in the presence of Ca²⁺ and Sr²⁺. However, crystals were not thick enough (mainly formed in two dimensions), as x-ray diffraction experiments showed diffraction patterns with low resolutions. Hence, obtaining high-quality crystals remains a challenge. The second part of my thesis demonstrates that the S-layer serves as a resistance mechanism to cationic antimicrobial peptides, which are produced by virtually all living organisms, including bacteria, fungi, plants and animals. S-layer positive strains were shown to be less susceptible to antimicrobial peptides than S-layer negative strains in MIC and killing assays. This protective effect was also observed when S-layer positive and negative strains were grown in biofilms. S-layer mediated resistance to antimicrobial peptides was further confirmed using epifluorescence microscopy. Addition of exogenous S-layer protein significantly increased the resistance of an S-layer negative strain to antimicrobial peptides. Overall, these results identify a new, previously unrecognized role for the S-layer as a resistance mechanism against antimicrobial peptides.
Rethinking Environmental Obligations in Corporate Insolvencies: What New Role for Lenders?

description: Abstract Environmental reclamation obligations are statutory mechanisms designed to regulate environmental protection by corporate entities. Bankruptcy laws on the other hand are meant to offer insolvent corporations an opportunity to reorganize their affairs, satisfy creditors claims and make a fresh start. In practice, the application of bankruptcy laws can undermine key environmental reclamation objectives, leading many to ask whether a corporation undergoing restructuring with significant outstanding environmental reclamation obligations should be able to commence bankruptcy proceedings to satisfy creditors’ claims? By employing the doctrinal and comparative research methodologies, this research interrogates that inquiry. It argues that, despite the importance of bankruptcy protection for corporations undergoing financial distress, environmental protection should be paramount. Although sustainable finance (SF) instruments have been deployed by banks to enable creditors to mitigate environmental concerns in their investments, the persistent recurrence of environmental reclamation issues in the oil and gas sector particularly during insolvencies, underscores the need for financial investors to strengthen their investment policies to reflect best practices providing the desired protection for the environment. The research finds that, although SF and environmental, social and governance (ESG) approaches, are commendable, they are insufficient in instilling adequate regulatory impact on the environment compared to judicial control offered by the courts. The thesis concludes that whilst judicial control mechanism is not without concerns, with government’s deliberate financial policy and judicial control to complement SF and ESG efforts, ESG and SF mechanisms can be strengthened to compel greater significant influence on best practices in lending.

description: Non-Markovian evolutions are responsible for a wide variety of physically interesting effects. Here, we study non-locality of the non-classical state of a system consisting of a qubit and an oscillator exposed to the effects of non-Markovian evolutions. We find that the different facets of non-Markovianity affect non-locality in different and non-obvious ways: ranging from pronounced insensitivity of the Bell function to quite a spectacular evidence of information kick-back.

description: We present a numerical model for the dynamics of thin viscous threads based on a discrete, Lagrangian formulation of the smooth equations. The model makes use of a condensed set of coordinates, called the centerline/spin representation: the kinematical constraints linking the centerline's tangent to the orientation of the material frame is used to eliminate two out of three degrees of freedom associated with rotations. Based on a description of twist inspired from discrete differential geometry and from variational principles, we build a full-fledged discrete viscous thread model, which includes in particular a discrete representation of the internal viscous stress. Consistency of the discrete model with the classical, smooth equations is established formally in the limit of a vanishing discretization length. The discrete models lends itself naturally to numerical implementation. Our numerical method is validated against reference solutions for steady coiling. The method makes it possible to simulate the unsteady behavior of thin viscous jets in a robust and efficient way, including the combined effects of inertia, stretching, bending, twisting, large rotations and surface tension.

description: This thesis considered the role of affect and reward in autistic features, based on the important role affective brain systems play in emotion and motivated behaviors known to be impacted in autistic individuals. I directly tested multiple affect-based hypotheses in children with and without an autism diagnosis and aimed to inform future clinical work by exploring several methodologies for examining both inter-individual (trait) and intra-individual (state) variation in measures of affect and reward. I first examined multiple behavioral domains (reward sensitivity, anxiety symptoms, and executive function) for associations with interest intensity in early childhood autism. I report that the executive functioning domain of attention shifting associated with interest intensity in early childhood, while there was no relation with general sensitivity to reward and anxiety symptoms. I then considered how to better characterize inter-individuality in reward sensitivity during early childhood, specifically regarding social rewards. I therefore developed and validated the Social Reward Questionnaire–Early Childhood (SRQ-EC) to quantify wanting and liking of distinctly rewarding social situations in young children. I found that autistic-like traits in a community sample associated with reduced wanting and liking of social rewards, particularly for large group interactions, suggesting potential utility of the SRQ-EC for future autism research. I additionally considered a protocol for investigating brain functional connectivity for associations with intra-individual affect variation in a community sample of adults, with relevance for designing future studies to examine neurobiological mechanisms of affective disorders that commonly co-occur in autism. My work replicates recent findings that variance in functional connectivity is largely attributable to individual identity, and that variance attributable to intra-individual affect variation is 7–100x smaller than what can be attributed to viewing condition. This thesis advances methodologies for measuring and modeling both inter- and intra-individual variation in autism, specifically in relation to affective processes which are difficult to measure in a laboratory setting. The methods presented and refined here could be used in future work to better understand state- and trait-like features in autism.

description: One of the Sustainable Development objectives is to promote life-long learning opportunities for all, but one of the Lifelong Learning competences is mathematical competence, which can be obtained studying mathematics at schools and universities. The question is how much and whether the course of mathematics should be included in the curriculum of the agronomy specialties at universities. The aim of the article is to highlight the insufficient amount of higher mathematics in the education of agriculture specialist in the context of sustainable development. The objectives of the study: to identify the importance of mathematics for agronomy specialists by analysing the role of the mathematics education for agronomy specialists and to analyse the proportion of mathematics courses in the curriculum of the agronomy programmes in the Baltics States and the Baltic Sea region’s higher education institutions. The mathematics education is important for agronomy specialists in many fields. Agronomy specialists need knowledge and skills in basic mathematics, in statistical analysis and interpretation, mathematical modelling, in scientific methods, in economic analysis. The knowledge and skills in a direct and indirect means is provided by mathematical studies at universities. In order to analyse the proportion of mathematics courses in study programmes of Agriculture, Agronomy and Horticulture, three universities of the Baltic States were compared: the Latvia University of Life Sciences and Technologies, Aleksandras Stulginskis University (Lithuania) and Estonian University of Life Sciences. For a more comprehensive analysis and comparison several universities from the Baltic Sea region were chosen that provide studies in agricultural sciences. Unfortunately, not all agronomy programmes in the Baltic Sea region contain the higher mathematics course that would help to understand the role of derivatives, integrals, and differential equations in the modelling process, as well as further developing general problem-solving skills.

description: Si presentano in questo studio alcuni materiali ceramici di produzione apula, finora inediti, provenienti da un sequestro e conservati presso l’ex Soprintendenza Archeologia della Lombardia. I materiali sono inquadrati all’interno del panorama vascolare apulo e attribuiti a specifiche mani pittoriche. I vasi, di probabile provenienza funeraria, sono inoltre analizzati sotto l’aspetto iconografico e iconologico al fine di comprenderne il loro significato e il valore all’interno della società indigena alla quale si ipotizza fossero destinati. Questa, seppur piccola, collezione offre infatti un interessante spaccato di alcune delle tematiche più importanti e diffuse nella ceramica apula di IV secolo a.C.

This paper presents a selection of vases of Apulian fabric, until now unpublished, coming from a seizure and stored in the former Soprintendenza Archeologia della Lombardia. These pieces are set within the Apulian workshops and they are attributed to specific pictorial hands. The paper undertakes an iconographic and iconological analysis of the vases, probably from funerary contexts, in order to understand their meaning and value within indigenous society, to which it is supposed they were addressed. This collection, even though small, offers an interesting image of some of the more important and common themes of Apulian pottery of the IV century B.C.

description: Sin dalla sua scoperta a Pompei nel 1938, la statuetta in avorio di manifattura indiana non ha smesso di porre interrogativi sul suo soggetto, sulla sua provenienza, sulla sua funzione prima di arrivare nel municipium campano. In questo contributo, dopo una disamina dello status quaestionis sulla statuetta (datazione, possibile iconografia, provenienza, contesto di rinvenimento) ci si chiederà chi potesse essere il suo proprietario e che cosa avrebbe potuto rappresentare per lui un manufatto tanto particolare. Una risposta potrebbe giungere dalle Metamorfosi di Ovidio, in particolare da una sezione del decimo libro dedicata a miti connessi con l’avorio e la prostituzione femminile, e dall’usanza romana di esporre, durante i banchetti, oggetti curiosi per stimolare la conversazione.

Since its discovery, which took place in Pompeii in 1938, the ivory statuette of Indian manufacture has not stopped asking questions about its subject, its origin, its function before its arrival in the Roman municipium. In this paper, after an examination of the status quaestionis on the statuette (dating, possible iconography, provenance, context of discovery) I will try to understand who could be its owner and therefore what a Pompeian of the first century could have seen in such a particular artifact. An answer may come from Ovid's Metamorphoses, in particular from a section of the tenth book dedicated to myths associated with ivory and female prostitution, and from the Roman custom to exhibit curious objects to stimulate conversation during banquets.

We followed the PRISMA guidelines and searched MEDLINE, EMBASE, PsycINFO, the Cochrane Library and Web of Science from database inception to May 2021 for articles published in English. We extracted data concerning demographics, intervention format, including Internet interventions, control group conditions and outcome measures. We used a random-effects model and calculated Hedges’ g values for the scores of employees receiving Internet interventions versus control conditions. This systematic review is registered as INPLASY202160082. Results. Data from 19 studies were included. These 19 studies included 5898 participants (2813 participants received Internet interventions, 3085 participants were in control groups). Conclusions. The findings suggest that Internet interventions can be effective in improving depression in employees. However, more randomized controlled trials are needed to provide better evidence regarding Internet interventions for employees with depression, and robust studies are needed to observe the effectiveness of Internet interventions.

description: Boundary conditions in quantum graph vertices are generally given in terms of a unitary matrix $U$. Observing that if $U$ has at most two eigenvalues, then the scattering matrix $\mathcal{S}(k)$ of the vertex is a linear combination of the identity matrix and a fixed Hermitian unitary matrix, we construct vertex couplings with this property: For all momenta $k$, the transmission probability from the $j$-th edge to $\ell$-th edge is independent of $(j,\ell)$, and all the reflection probabilities are equal. We classify these couplings according to their scattering properties, which leads to the concept of generalized $δ$ and $δ'$ couplings.

description: The random-phase approximation to the ground state correlation energy (RPA) in combination with exact exchange (EX) has brought Kohn-Sham (KS) density functional theory one step closer towards a universal, "general purpose first principles method". In an effort to systematically assess the influence of several correlation energy contributions beyond RPA, this work presents dissociation energies of small molecules and solids, activation energies for hydrogen transfer and non-hydrogen transfer reactions, as well as reaction energies for a number of common test sets. We benchmark EX+RPA and several flavors of energy functionals going beyond it: second-order screened exchange (SOSEX), single excitation (SE) corrections, renormalized single excitation (rSE) corrections, as well as their combinations. Both the single excitation correction as well as the SOSEX contribution to the correlation energy significantly improve upon the notorious tendency of EX+RPA to underbind. Surprisingly, activation energies obtained using EX+RPA based on a KS reference alone are remarkably accurate. RPA+SOSEX+rSE provides an equal level of accuracy for reaction as well as activation energies and overall gives the most balanced performance, which makes it applicable to a wide range of systems and chemical reactions.

description: The chemical composition and biological activities of the essential oil (EO) from the rhizomes of Zingiber striolatum Diels were reported for the first time. Forty-five compounds were identified, and represented 95.7% of the total composition of the EO. The predominant components of the EO were β-phellandrene (24.0%), sabinene (17.3%), β-pinene (11.4%), geranyl linalool (8.6%), terpinen-4-ol (8.3%), α-pinene (5.6%) and crypton (4.5%). The EO revealed a weak DPPH and ABTS radical-scavenging activity. The EO exhibited significant antimicrobial activity with the inhibition zones (12.86–24.62 mm) and MIC (0.78–3.12 mg/mL) against Enterococcus faecalis, Staphylococcus aureus, Pseudomonas aeruginosa, Escherichia coli, Candida albicans. The EO showed significant cytotoxicity against human leukemic (K562), lung cancer (A549) and prostatic carcinoma (PC-3) cell lines with the IC50 values of 29.67, 48.87 and 86.05 μg/mL, respectively. Thus, the EO could be regarded as a bioactive natural product with potential for utilization in the cosmetic and pharmaceutical industry.

description: When a Brownian object interacts with non-interacting gas particles under non-equilibrium conditions, the energy dissipation associated to the Brownian motion causes an additional force on the object as a `momentum transfer deficit'. This principle is demonstrated first by a new NESS model and then applied to several known models such as adiabatic piston for which simple explanation has been lacking.

description: Graphene superlattices formed by periodic strain are considered theoretically. It is shown that electron energy spectrum consists of minibands obtained by folding of the cone at the boundaries of the superlattice Brillouin zone with very narrow anticrossing regions. Light absorption under direct interminiband transitions is shown to be frequency dependent and dichroic. Giant dichroism of absorption is demonstrated for doped graphene superlattices. Asymmetrical graphene superlattices act as quantum ratchets allowing for generation of photocurrent at absorption of normally incident light. The helicity-dependent photocurrent spectrum is calculated for doped superlattices with various asymmetries.

Stiefel’s method
article

description: In this paper, we consider the linear optimization models’ application problems in the research processes and in the didactics processes. Our target is to convince the colleagues about preferences of Eduard Stiefel’s method comparing with widespread George Bernard Dantzig’s simplex method. Indeed, the Stiefel’s method provides researchers and teachers with clear and pithy interpretations of linear model. Our pedagogical praxis during long time period conclusively confirms that Stiefel’s method makes the theory of linear optimization match easier for understanding and for active employing to students especially in the specialities with limited mathematical education. We offer in this paper also some new theoretical concepts and methods adapted for the linear model information analysis (the concept of general optimal plan, the methods of the profounder sensitivity analysis), and we appeal economists to interpret simplex predicates as productions functions in a broad sense.

description: We find an analytic formulation of the notion of Hopf image, in terms of the associated idempotent state. More precisely, if $π:A\to M_n(\mathbb C)$ is a finite dimensional representation of a Hopf $C^*$-algebra, we prove that the idempotent state associated to its Hopf image $A'$ must be the convolution Cesàro limit of the linear functional $ϕ=tr\circπ$. We discuss then some consequences of this result, notably to inner linearity questions.

A simple closure approximation for slow dynamics of a multiscale system: nonlinear and multiplicative coupling

description: Multiscale dynamics are ubiquitous in applications of modern science. Because of time scale separation between relatively small set of slowly evolving variables and (typically) much larger set of rapidly changing variables, direct numerical simulations of such systems often require relatively small time discretization step to resolve fast dynamics, which, in turn, increases computational expense. As a result, it became a popular approach in applications to develop a closed approximate model for slow variables alone, which both effectively reduces the dimension of the phase space of dynamics, as well as allows for a longer time discretization step. In this work we develop a new method for approximate reduced model, based on the linear fluctuation-dissipation theorem applied to statistical states of the fast variables. The method is suitable for situations with quadratically nonlinear and multiplicative coupling. We show that, with complex quadratically nonlinear and multiplicative coupling in both slow and fast variables, this method produces comparable statistics to what is exhibited by an original multiscale model. In contrast, it is observed that the results from the simplified closed model with a constant coupling term parameterization are consistently less precise.

description: Plants are capable of perceiving and responding to biotic and abiotic stress. They have evolved a variety of mechanisms to help them recognize and trigger rapid responses to both chemical and mechanical stimuli. These signals coordinate plant growth, development, and innate immune responses. However, we have limited knowledge about how mechanical signals are perceived and transduced during the plant immune response. In this study, we investigated the potential role of PIEZO, a mechanosensitive ion channel that is responsible for cellular mechanotransduction in both the plant and animal kingdoms, during the plant immune responses. Publicly- available RNAseq data revealed that PIEZO expression remained constant and unaltered in response to a variety of phytopathogens or elicitors. We, then, conducted infectious growth assays on piezo mutants in Arabidopsis thaliana plants. Our results indicated that piezo mutants, pzo1-1 and pzo1-5, were more susceptible to Pseudomonas syringae pv. tomato (Pst) DC3000 and to the P. syringae hrcC- mutant confirming PIEZO’s role in plant defense and PTI. We further explored disease progression with necrotrophic fungi, Alternaria brassisicola and Botrytis cinerea, on piezo mutant plants and found enhanced fungal growth compared to the wild type (Col-0) with Botrytis. Building upon these findings, we probed the role of PIEZO in the growth-defense tradeoff using a root growth inhibition assay with flg22 as the MAMP elicitor. pzo1-1 was less sensitive to flg22 treatment with less reduction in root growth compared to wild type whereas pzo1-5 shows no difference in reduction compared to Col-0. In addition, we investigated whether PIEZO operates upstream of the main NADPH-oxidase, RBOHD, and the associated oxidative burst that occurs in early defense. There was no significant difference in Reactive Oxygen Species (ROS) production between piezo mutants and the wild type in an apoplastic ROS assay with a MAMP elicitor (flg22) and also with Ca2+ flux leaf disk assay. In conclusion, we demonstrated a potential role for PIEZO in plant immune defense responses and the growth-defense tradeoff.
