description: We construct a supersymmetric quantum mechanical model in which the energy eigenvalues of the Hamiltonians are the products of Riemann zeta functions. We show that the trivial and nontrivial zeros of the Riemann zeta function naturally correspond to the vanishing ground state energies in this model. The model provides a natural form of supersymmetry.

description: Los generadores automáticos web permiten crear webs personalizadas sin necesidad de conocimientos técnicos. Sin embargo, estos no contienen información que pueda guiar la generación de las webs dentro de un dominio concreto. Este trabajo de fin de grado presenta WebSPL, una herramienta prototipo para asistir al usuario en la generación, prueba y despliegue automático de sitios web teniendo en cuenta información de dominio. Para ello se aplican técnicas de la ingeniería de las líneas de producto para featurizar distintos dominios web y se usa una interfaz para la selección de características, delegando en un motor de análisis la validación de las configuraciones y finalmente generando los sitios web de manera automática completamente personalizados por el usuario. Esta herramienta actualmente permite generar webs dentro del dominio e-commerce y el dominio de páginas webs personales estilo blogs, aunque es fácilmente aplicable a otros dominios. El objetivo principal del desarrollo de este proyecto ha sido automatizar las diferentes etapas del ciclo de desarrollo software y permitir al usuario inexperto poder crear su página web propia y personalizada, además de dar soporte al usuario experto para generar webs personalizadas para sus clientes de una manera sencilla, rápida y reduciendo costes. El proyecto es open-source y dispone de guías y manuales de usuario para la facilidad de cualquier desarrollador a extender la herramienta. Este trabajo ha sido publicado en SISTEDES'22, donde recibió muy buenas valoraciones (2,2,3) y se presentó delante de la comunidad investigadora de software española durante la conferencia.

description: We investigate the dispersion relations of TE resonances in different graphene-dielectric structures. Previous work has shown that when a graphene layer is brought into contact with a dielectric material, a gap can appear in its electric band structure. This allows for the formation of TE-plasmons with unusual dispersion relations. In addition, if the dielectric has a finite thickness, graphene strongly modifies the behavior of the waveguiding modes by introducing dissipation above a well-defined cutoff frequency thus providing the possibility of mode filtering. This cutoff and the properties of TE-plasmons are closely related to the pair-creation threshold of graphene thus representing quantum mechanical effects that manifest themselves in the electromagnetic response.

description: Since the early 2000s the European Union has promoted and supported the development of cross-border and digital means for conducting business and running governments. This strategic focus, carried out through the initial Lisbon Strategy1 and the follow-up Europe 2020 strategy2 has contributed to a widespread shift toward e-governments and e-commerce. Ultimately, this has transformed the relationships between governments, citizens and business. From a technical perspective, a wide range of new information systems and communication methods have become available that streamline and automate transactions, enable integration of information and service delivery, and enhance collaboration between participants. It has also changed the ways of conducting public and private business, documenting activities, and making information available for reuse, aiding decision-making and supporting accountability. Much of this information has to remain available for long periods, often beyond the life expectancy of individual information systems or technological components. This poses a significant challenge for both the original data creators and digital archives that have to be capable of both dealing with the most current information technology, and with “saving” information from a variety of legacy systems. In order to deal with these challenges there is a need to bridge the gap between the methods used in digital preservation and content creation and introduce additional practical interoperability into the solutions used for a Digital Single Market and digital preservation infrastructures. The European Commission recognised the need in 2013 and funded the E-ARK project3 (2014 – 2017) which successfully delivered a set of principles, specifications and tools that provided an interoperable and international solution for the sustainable long-term availability of digital information. This paper describes the solutions first developed during the E-ARK project, focusing on the SIP format, as well as the steps the European Commission is taking towards building a thriving digital preservation community around the E-ARK outcomes.

description: This work proposes a new avenue in the search for CP-violating odd-electric and even-magnetic nuclear moments. A promising candidate to find such moments in the ground state is the quadrupole-deformed and octupole-correlated nucleus 227-actinium. In this nucleus, the 27.4-keV $E1$~transition that connects the $3/2^+$ parity-doublet partner and the $3/2^-$ ground state is perfectly suited to apply the sensitive technique of recoil-free selfabsorption, commonly known as Mössbauer spectroscopy. In this experimental approach, the lifetime of the $3/2^+$ upper parity-doublet partner allows an estimate of the lower limit of $ΔE = 2\cdot Γ_γ$= $23.7(1) \times 10^{-9}$ eV for the achievable energy resolution to be made. This resolution must be exceeded by the interaction of a CP-violating moment and the corresponding multipole moment of the field distribution in the lattice. This work presents the first ideas for patterns caused by CP-violating moments on the expected quadrupole splitting and nuclear Zeeman effect.

description: When inferring parameters from a Gaussian-distributed data set by computing a likelihood, a covariance matrix is needed that describes the data errors and their correlations. If the covariance matrix is not known a priori, it may be estimated and thereby becomes a random object with some intrinsic uncertainty itself. We show how to infer parameters in the presence of such an estimated covariance matrix, by marginalising over the true covariance matrix, conditioned on its estimated value. This leads to a likelihood function that is no longer Gaussian, but rather an adapted version of a multivariate t-distribution, which has the same numerical complexity as the multivariate Gaussian. As expected, marginalisation over the true covariance matrix improves inference when compared with Hartlap et al.'s method, which uses an unbiased estimate of the inverse covariance matrix but still assumes that the likelihood is Gaussian.

Therapeutic Hypothermia to Reduce Cardiac Arrest-Related Neurological Deficits and Mortality
Creators: name: Legare, Angel
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2017

description: Purpose: The purpose of this clinical review is to determine if induced therapeutic hypothermia is effective in reducing neurological deficits and mortality in cardiac arrest patients. Methods: PubMed, Cochrane Review Database, Embase, and Trip database were utilized. A common set of search terms including "induced hypothermia", "therapeutic hypothermia”, "cardiovascular resuscitation", “cardiac arrest”, "neurological deficits", “neurological outcome”
and “mortality” guided the search. A total of three individual studies that were included for final results review. Results: Clinically based trials revealed that induced therapeutic hypothermia can improve both survival rates and neurological outcomes in cardiac arrest patients compared to cardiac arrest
patients that do not receive therapeutic hypothermia. Conclusion: Although more research needs to be done to make therapeutic hypothermia implemented
across all cardiac arrest patients, current research has suggested that therapeutic hypothermia implantation in cardiac arrest protocols can prove to be extremely beneficial in improving patient survival rates and neurological outcome.

description: The article, presents the study of the regularity of two thermoelastic beam systems defined by the Timoshenko beam model coupled with the heat conduction of Green-Naghdiy theory of type III, both mathematical models are differentiated by their coupling terms that arise as a consequence of the constitutive laws initially considered. The systems presented in this work have 3 fractional dampings: $μ_1(-Δ)^τϕ_t$, $μ_2(-Δ)^σψ_t$ and $K(-Δ)^ξθ_t$, where $ϕ,ψ$ and $θ$ are transverse displacement, rotation angle and empirical temperature of the bean respectively and the parameters $(τ,σ,ξ)\in [0,1]^3$. It is noted that for values 0 and 1 of the parameter $τ$, the so-called frictional or viscous damping will be faced, respectively. The main contribution of this article is to show that the corresponding semigroup $S_i(t)=e^{\mathcal{B}_it}$, with $i=1,2$, is of Gevrey class $s>\frac{r+1}{2r}$ for $r=\min \{τ,σ,ξ\}$ for all $(τ,σ,ξ)\in R_{CG}:= (0, 1)^3$. It is also showed that $S_1(t)=e^{\mathcal{B}_1t}$ is analytic in the region $R_{A_1}:=\{(τ,σ, ξ)\in [\frac{1}{2},1]^3\}$ and $S_2(t)=e^{\mathcal{B}_2t}$ is analytic in the region $R_{A_2}:=\{(τ,σ, ξ)\in [\frac{1}{2},1]^3/ τ=ξ\}$.

Effective Theory for Baryogenesis with a Majorana Fermion Pair Coupled to Quarks

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: With a goal toward explaining the observed baryon asymmetry of the Universe, we extend the standard model (SM) by adding a vector-vector dimension-six effective operator coupling a new Dirac fermion $χ$, uncharged under the SM gauge symmetries but charged under baryon number, to a quark-like up-type fermion and two identical down-type fermions. We introduce baryon number violation by adding Majorana masses to $χ$, which splits the Dirac fermion into two Majorana fermions with unequal masses. We speculate on the origin of the effective operator, the Majorana mass, and the new physics sector connection to the SM, by considering some ultraviolet completion examples. In addition to the baryon number violation, we show that $C$ and $CP$ invariances can be violated in the theory, and the interference between tree and loop amplitudes with on-shell intermediate states can lead to a baryon asymmetry in $χ$ decay and scattering processes. We write down the Boltzmann equation for baryon number in the early Universe incorporating the decay and scattering baryon asymmetries. We provide numerical estimates for the baryon asymmetry generated, and for the neutron-antineutron oscillation rate.

On the relation between the subadditivity cone and the quantum entropy cone

description: Given a multipartite quantum system, what are the possible ways to impose mutual independence among some subsystems, and the presence of correlations among others, such that there exists a quantum state which satisfies these demands? This question and the related notion of a \textit{pattern of marginal independence} (PMI) were introduced in arXiv:1912.01041, and then argued in arXiv:2204.00075 to be central in the derivation of the holographic entropy cone. Here we continue the general information theoretic analysis of the PMIs allowed by \textit{strong subadditivity} (SSA) initiated in arXiv:1912.01041. We show how the computation of these PMIs simplifies when SSA is replaced by a weaker constraint, dubbed \textit{Klein's condition} (KC), which follows from the necessary condition for the saturation of subadditivity (SA). Formulating KC in the language of partially ordered sets, we show that the set of PMIs compatible with KC forms a lattice, and we investigate several of its structural properties. One of our main results is the identification of a specific lower dimensional face of the SA cone that contains on its boundary all the extreme rays (beyond Bell pairs) that can possibly be realized by quantum states. We verify that for four or more parties, KC is strictly weaker than SSA, but nonetheless the PMIs compatible with SSA can easily be derived from the KC-compatible ones. For the special case of 1-dimensional PMIs, we conjecture that KC and SSA are in fact equivalent. To make the presentation self-contained, we review the key ingredients from lattice theory as needed.

Efficacy of SSRIs for treating depression in Alzheimer’s disease
Creators: name: Nhor, Cherry
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2018

description: Contrary to popular belief, memory loss and other cognitive abilities
                    severe enough to interfere with daily life are not a normal part of aging.
                    Worldwide, 50 million people are living with a degenerative brain disease known
                    as dementia. In the U.S., 5.7 million Americans are living with the most common
                    form of dementia: Alzheimer’s disease (AD).1 AD is a type of dementia that
                    causes problems with memory, thinking, and behavior. It is often difficult to
                    distinguish depression in older adults without cognitive changes versus
                    depression in those affected with Alzheimer’s dementia. Depression is one of the
                    most frequent psychiatric complications of AD, affecting as many as 50% of
                    patients. To address this disparity, one must first understand the criteria in
                    diagnosing depression in AD. Current guidelines such as the National Institute
                    of Mental Health-depression in Alzheimer’s disease (NIMH-dAD) and the Cornell
                    Scale for Depression in Dementia (CSDD) have been used to diagnose depression in
                    AD. Once the diagnosis of depression in AD has been made, consideration of
                    effective treatment is required. Depression in AD is associated with greater
                    morbidity and mortality, which does not only affect the patient but the families
                    and caregivers, and society as a whole. The estimated societal costs due to AD
                    are between $100 billion per year, and are projected to double by 2020 and
                    triple by 2040. In addition, depression in AD may also be associated with
                    increased risk of suicide. This review evaluated a Cochrane review as well as
                    two other clinical trials to examine the efficacy of SSRI’s at reducing
                    depressive symptoms in AD. The conclusion suggested that there is weak evidence
                    to support the use of SSRI’s in the treatment of patients with AD and
                    depression. However, this conclusion is based on a small number of studies with
                    small sample sizes. In order to decrease morbidity and mortality among patients
                    with AD who suffer with depression, there must be further research to support
                    the efficacy of SSRI’s.

description: The quantum SWITCH is an example of a process with an indefinite causal structure, and has attracted attention for its ability to outperform causally ordered computations within the quantum circuit model. To date, realisations of the quantum SWITCH have relied on optical interferometers susceptible to minute path length fluctuations, complicating their design, limiting their performance and posing an obstacle to extending the quantum SWITCH to multiple parties. In this Letter we overcome these limitations by demonstrating an intrinsically stable quantum SWITCH utilizing a common-path geometry facilitated by a novel reciprocal and universal $\mathrm{SU}(2)$ polarization gadget. We certify our design by successfully performing a channel discrimination task with near unity success probability.

The Use of Dexamethasone vs Prednisone in the Treatment of Asthma Exacerbation
Creators: name: Higgins, Leana
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2017

description: Asthma accounts for 2.1 million unscheduled ED visits annually, with a
prevalence of 8.4% of the US population. Systemic corticosteroids serve as a
cornerstone of acute asthma therapy, decreasing relapse rate, length of stay, and
hospitalization rates. Since prednisone has multiple side effects and problematic
compliance, studies have been conducted to determine if dexamethasone is as effective
in the treatment of asthma exacerbation. This review evaluated a Cochrane systematic
review, as well as three additional studies not included in that review. The conclusion
was that dexamethasone is a promising alternative to prednisone in treating asthma
exacerbation in both adults and children. However, in order for this possibility to be
readily adopted into guidelines and clinical practice, higher quality and more consistent
data needs to be obtained.
Treatment Approach to a Patient with Lewy Body Dementia
Creators: name: Harris, Kami
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2017

description: Although LBD [Lewy Body Dementia] and AD [Alzheimer's Disease] share many of the same symptoms, their etiologies differ as does their approach to treatment. Therefore, it is important for the clinician to be able to assess for differences between the two. LDB has earlier detrimental effects on quality of life in comparison to AD. The approach to therapy should be targeted and an intervention should be initiated as early as possible. There is no cure for either at this time, therefore the mainstay of therapy is symptom management. The goal of treatment is to improve quality of life, maintain as much independence as possible, and minimize adverse reactions to medications. Among available medications, cholinesterase inhibitors have shown some benefit in cognitive functioning for AD, but less for LBD. Even within the subset of LBD, DLB patients respond better to cholinesterase inhibitors compared to PDD patients. This is likely because the pathology of DLB is more similar to AD than PDD. In contrast, treatment with levodopa is more effective in treating parkinsonian symptoms in patients with PDD compared to LDB. This is likely due to PDD being more similar to Parkinson’s disease pathology than DLB. Research continues to investigate appropriate therapies for both AD and LBD. Unfortunately, LBD lags behind most other neurological disorders in research, treatment, and awareness.

description: In d=2+1 dimensions, there exist field theories which are non-relativistic and superconformal. These theories describe two species of anyons, whose spins differ by 1/2, interacting in a harmonic trap. We compute the dimensions of chiral primary operators. These operators receive large anomalous dimensions which are related to the unusual angular momentum properties of anyons. Surprisingly, we find that the dimensions of some chiral primary operators violate the unitarity bound and we trace this to the fact that the associated wavefunctions become non-normalisable. We also study BPS non-perturbative states in this theory: these are Jackiw-Pi vortices. We show that these emerge at exactly the point where perturbative operators hit the unitarity bound. To describe the low-energy dynamics of these vortices, we construct a novel type of supersymmetric gauged linear sigma model.

description: To constrain the nature and fraction of the ionized gas outflows in AGNs, we perform a detailed analysis on gas kinematics as manifested by the velocity dispersion and shift of the [O III] λ5007 emission line, using a large sample of ~39,000 type 2 AGNs at z<0.3. First, we confirm a broad correlation between [O III] and stellar velocity dispersions, indicating that the bulge gravitational potential plays a main role in determining the [O III] kinematics. However, [O III] velocity dispersion is on average larger than stellar velocity dispersion by a factor of 1.3-1.4 for AGNs with double Gaussian [O III], suggesting that the non-gravitational component, i.e., outflows, is almost comparable to the gravitational component. Second, the increase of the [O III] velocity dispersion (after normalized by stellar velocity dispersion) with both AGN luminosity and Eddington ratio suggests that non-gravitational kinematics are clearly linked to AGN accretion. The distribution in the [O III] velocity - velocity dispersion diagram dramatically expands toward large values with increasing AGN luminosity, implying that the launching velocity of gas outflows increases with AGN luminosity. Third, the majority of luminous AGNs presents the non-gravitational kinematics in the [O III] profile. These results suggest that ionized gas outflows are prevalent among type 2 AGNs. On the other hand, we find no strong trend of the [O III] kinematics with radio luminosity, once we remove the effect of the bulge gravitational potential, indicating that ionized gas outflows are not directly related to radio activity for the majority of type 2 AGNs.

Holography for anisotropic branes with hyperscaling violation

Publisher: name: arXiv
Year: 2015
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: In this paper, based on the principles of Gauge/gavity duality, we explore the field theory description of certain special class of strongly coupled hyperscaling violating QFTs in the presence of scalar deformations near the \textit{effective} dynamical scale ($ r_F $) of the theory. In the language of the AdS/CFT duality, the scalar deformations of the above type could be thought of as being sourced due to some massless scalar excitation in the bulk which explicitly break the $ SO(2) $ rotational invariance along the spatial directions of the brane. As a consequence of these deformations, it turns out that when we probe such QFTs in terms of its non-local observable like, the entanglement entropy as well as the Wilson operator they indeed receive finite contributions near the effective dynamical scale ($ r_F $) of the theory.

description: Heart failure is typically diagnosed with a global function assessment, such as ejection fraction. However, these metrics have low discriminate power, failing to distinguish different types of this disease. Quantifying local deformations in the form of cardiac strain can provide helpful information, but it remains a challenge. In this work, we introduce WarpPINN, a physics-informed neural network to perform image registration to obtain local metrics of the heart deformation. We apply this method to cine magnetic resonance images to estimate the motion during the cardiac cycle. We inform our neural network of near-incompressibility of cardiac tissue by penalizing the jacobian of the deformation field. The loss function has two components: an intensity-based similarity term between the reference and the warped template images, and a regularizer that represents the hyperelastic behavior of the tissue. The architecture of the neural network allows us to easily compute the strain via automatic differentiation to assess cardiac activity. We use Fourier feature mappings to overcome the spectral bias of neural networks, allowing us to capture discontinuities in the strain field. We test our algorithm on a synthetic example and on a cine-MRI benchmark of 15 healthy volunteers. We outperform current methodologies both landmark tracking and strain estimation. We expect that WarpPINN will enable more precise diagnostics of heart failure based on local deformation information. Source code is available at https://github.com/fsahli/WarpPINN.

Prescription drug monitoring programs: a response to the opioid epidemic
Creators: name: Tiu, Tricia
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2018

description: Background: The non-medical use of prescription opioids is a
                    significant problem in the United States, with significant health and economic
                    consequences. The nationwide implementation and expansion of prescription drug
                    monitoring programs (PDMPs) has been utilized to reduce the incidence of doctor
                    shopping, influence prescribing practices, and improve patient treatment
                    decisions. Objective: The purpose of this paper is to describe the available
                    primary literature on prescription drug monitoring programs. Methods: Peer
                    reviewed research articles, literature reviews, and opinion articles on
                    prescription drug monitoring programs from 2000 to 2017 were identified by
                    searching PubMed/Medline, CINAHL, Embase, PsycInfo, using ‘prescription drug
                    monitoring programs’ OR ‘PDMP’ OR ‘prescription monitoring programs’ AND
                    ‘opioids’ as search terms or MeSH terms. Article bibliographies were also search
                    manually for applicable papers. Results: Nineteen primary research articles were
                    included for analysis. Evidence of impact of prescription drug monitoring
                    programs on opioid-related outcomes is inconclusive. Conclusions: As PDMP
                    implementation continues to expand, there needs to be continued focus on
                    specific PDMP characteristics to determine what is the most effective at
                    reducing opioidrelated outcomes.

description: The local induction equation, or the binormal flow on space curves is a well-known model of deformation of space curves as it describes the dynamics of vortex filaments, and the complex curvature is governed by the nonlinear Schrödinger equation (NLS). In this paper, we present its discrete analogue, namely, a model of deformation of discrete space curves by the discrete nonlinear Schrödinger equation (dNLS). We also present explicit formulas for both NLS and dNLS flows in terms of the $τ$ function of the 2-component KP hierarchy.

A partially wetting film of water and surfactant under the influence of a propagating MHz surface acoustic wave

description: We use both theory and experiment to study the response of {\it partially wetting} films of water and surfactant solutions to a propagating MHz vibration in the solid substrate in the form of a Rayleigh surface acoustic wave (SAW). The SAW invokes a drift of mass in the liquid film, which is associated with the Schlichting boundary layer flow (also known as the Schlichting streaming). We study thin films that are governed by a balance between the drift and capillary stress alone. We demonstrate weak capillary contributions, such as for silicon oil films, support dynamic wetting and lead to the spreading of the liquid over the solid substrate along the path of the SAW. Strong capillary contributions, such as for water films, support however a concurrent dynamic wetting and dewetting along the path of the SAW, such that the film displace along the solid substrate. In addition, such films may support the formation of a capillary train-wave that propagate along the the same path. We further note the mechanism for film dynamics we discuss here is different to the more familiar Eckart streaming mechanism, which is associated with a film thickness that is greater than the wavelength of the sound leakage off the SAW and usually observed to support the motion of drops. The thickness of the films we discuss here is small in respect to the wavelength of the sound leakage, rendering contributions from the Eckart streaming, acoustic radiation pressure, and the attenuation of the SAW small.
