description: Purpose: This study investigated the effects of cueing for increased loudness and reduced speech rate on scaled intelligibility and acoustics of speech produced by Mandarin speakers with hypokinetic dysarthria due to Parkinson’s Disease (PD). Method: Eleven speakers with PD read passages in habitual, loud, and slow speaking conditions. Fifteen listeners rated ease-of-understanding (EOU) of the speech samples on a visual-analog-scale. Effects of the cues on EOU, vocal loudness, pitch range, pause duration and frequency, articulation rate, and vowel space, as well as relationships between EOU gains and acoustic features were analyzed. Results: EOU increased significantly in the loud condition only. The loud cue resulted in increased intensity and the slow cue resulted both in reduced articulation rate and increased pause frequency. In the loud condition, EOU increased significantly as intensity increased and vowel centralization decreased. In the slow condition, EOU tended to increase as intensity increased and vowel centralization decreased, but did not reach statistical significance. Conclusion: Cueing for loud speech may yield greater EOU gains than cueing for slow speech in Mandarin speakers with PD. Theoretical and clinical implications are discussed, although further investigations with more participants and a larger range of dysarthria severity are warranted.

description: Homology theory has attracted great attention because it can provide novel and powerful solutions to address coverage problems in wireless sensor networks. They usually use an easily computable algebraic object, Rips complex, to detect coverage holes. But Rips complex may miss some coverage holes in some cases. In this paper, we investigate homology-based coverage hole detection for wireless sensor networks on sphere. The situations when Rips complex may miss coverage holes are first presented. Then we choose the proportion of the area of coverage holes missed by Rips complex as a metric to evaluate the accuracy of homology-based coverage hole detection approaches. Three different cases are considered for the computation of accuracy. For each case, closed-form expressions for lower and upper bounds of the accuracy are derived. Simulation results are well consistent with the analytical lower and upper bounds, with maximum differences of 0.5% and 3% respectively. Furthermore, it is shown that the radius of sphere has little impact on the accuracy if it is much larger than communication and sensing radii of each sensor.

description: Theoretical investigation has been carried out on the tunable electromagnetic surface waves propagating along the Graphene loaded semi-infinite left-handed media (LHM) interface. The analytical modeling of the graphene has been done in the frame work of Kubo's formulation. The split ring resonators (SRRs) model and Kramers-Kronig relations-based causality principle have been used to simulate the GHz-LHMs and THz-LHMs respectively. To realize the graphene loaded LHM interface, the impedance boundary conditions (IBCs) have been employed. The dispersion curves, effective mode index, propagation length, penetration depth, phase velocity and fields profiles of surface waves supported by graphene loaded GHz-LHM and THz-LHM have been computed numerically. It has been concluded that the graphene parameters can be used to tune the characteristics of surface waves in GHz and THz range. The proposed study may have potential applications in designing the near field imaging platforms, communication devices and tunable surface wave guides.

description: We derive a necessary and sufficient condition for the thermalization of a local observable in a closed quantum system which offers an alternative explanation, independent of the eigenstate thermalization hypothesis, for the thermalization process. We also show that this approach is useful to investigate thermalization based on a finite-size scaling of numerical data. The condition follows from an exact representation of the observable as a sum of a projection onto the local conserved charges of the system and a projection onto the non-local ones. We show that thermalization requires that the time average of the latter part vanishes in the thermodynamic limit while time and statistical averages for the first part are identical. As an example, we use this thermalization condition to analyze exact diagonalization data for a one-dimensional spin model. We find that local correlators do thermalize in the thermodynamic limit although we find no indications that the eigenstate thermalization hypothesis applies.

Speech therapy for children
Speech, Intelligibility of
Cerebral palsy

description: The paucity of evidence and detail in the literature regarding speech treatment for children with dysarthria due to cerebral palsy (CP) renders it difficult for researchers to replicate studies and make further inroads into this area in need of exploration. Furthermore, for speech-language pathologists (SLPs) wishing to follow treatments that the literature indicates have promise, little guidance is available on the details of the treatments that yielded the positive results. The present article details the implementation of two treatment approaches in speech treatment research for children with dysarthria: Speech Systems Intelligibility Treatment (SSIT) and the Lee Silverman Voice Treatment LOUD (LSVT LOUD). Specific strategies, primarily for treatment, but also for outcome measurement and acoustic analysis of dysarthric speech, are described. These techniques are provided for researchers and clinicians to consider implementing in order to advance speech treatment for this population. Recent results from research using these approaches are presented, including findings of acoustic vowel space changes following both speech treatments.

description: Purpose: Speech production deficits and reduced intelligibility are frequently noted in individuals with Down syndrome (DS) and are attributed to a combination of several factors. This study reports acoustic data on vowel production in young adults with Down syndrome, and relates these findings to perceptual analysis of speech intelligibility. Method: Participants were eight young adults with DS, as well as eight age- and gender-matched typically developing (TD) controls. Several different acoustic measures of vowel centralization and variability were applied to tokens of corner vowels (/ɑ/, /æ/, /i/, /u/) produced in common English words. Intelligibility was assessed for single-word productions of speakers with DS, by means of transcriptions from 14 adult listeners. Results: Group differentiation was found for some, but not all, of the acoustic measures. Low vowels were more acoustically centralized and variable in speakers with DS than TD controls. Acoustic findings were associated with overall intelligibility scores. Vowel Formant Dispersion was the most sensitive measure in distinguishing DS and TD formant data. Conclusion: Corner vowels are differentially affected in speakers with DS. The acoustic characterization of vowel production and its association with speech intelligibility scores within the DS group support the conclusion of motor control deficits in the overall speech impairment. Implications are discussed for effective treatment planning.

description: Although the spin is regarded as a fundamental property of the electron, there is no universally accepted spin operator within the framework of relativistic quantum mechanics. We investigate the properties of different proposals for a relativistic spin perator. It is shown that most candidates are lacking essential features of proper angular momentum operators, leading to spurious Zitterbewegung (quivering motion) or violating the angular momentum algebra. Only the Foldy-Wouthuysen operator and the Pryce operator qualify as proper relativistic spin operators. We demonstrate that ground states of highly charged hydrogen-like ions can be utilized to identify a legitimate relativistic spin operator experimentally.

title: The impact of dietary arginine and citrulline in the neonatal gut
Creators: name: Hurley, Martin Fredrick
Publisher: name: Memorial University of Newfoundland
Year: 2023

description: Citrulline is a non-protein amino acid that is converted to arginine in the urea cycle through the activities of argininosuccinate synthase (ASS) and argininosuccinate lyase (ASL); as such, citrulline supplementation may increase arginine availability. Arginine deficiency in preterm infants is associated with the serious gastrointestinal infection, necrotizing enterocolitis (NEC). Low arginine may contribute to NEC via inadequate nitric oxide (NO) synthesis, which would impair blood flow to the gut. Arginine is converted to NO by nitric oxide synthase (NOS), but citrulline may be a more effective precursor of NO, as ASS and ASL are co-localized with NOS. Preterm infants are more susceptible to NEC during the transition from parenteral nutrition (PN) to enteral feeding. In piglets with PN-induced intestinal atrophy, we hypothesized that supplemental citrulline would lead to greater NO production and higher blood flow to the intestine. Piglets (7-10 days, n = 20) received venous and gastric catheters and a probe to measure superior mesenteric artery (SMA) blood flow. Intestinal atrophy was induced with PN feeding. On day 4, piglets were randomized to enteral refeeding of an elemental formula with arginine concentration equivalent to 1) sow milk (Low Arg), 2) 2.5 times sow milk (High Arg) or 3) Low Arg plus citrulline (Cit) with arginine plus citrulline equimolar to High Arg. At the initiation of enteral feeding, SMA blood flow was measured for 10 hours. On day 5, whole body protein and NO synthesis were measured with tracers. Whole body protein synthesis was highest in High Arg group compared to Low Arg and Cit groups, suggesting that the concentration of dietary arginine supplied by milk does not meet the whole body needs of a neonate with compromised intestinal function; furthermore, citrulline was not able replace arginine for protein synthesis. NO synthesis and SMA blood flow were highest in the Cit group, suggesting that citrulline was a better precursor for NO synthesis than arginine, and supported better blood flow to the gut. Citrulline supplementation with arginine at concentrations greater than that in milk may be a means to improve arginine status and enhance intestinal recovery in neonates who are at high risk for NEC during the transition from parenteral to enteral feeding.

description: Objective—As prenatal genetic testing (GT) and Preimplantation Genetic Diagnosis (PGD) use increase, providers in many specialties may play roles in patient discussions and referrals. Hence, we examined key aspects of neurologists’ and psychiatrists’ views and approaches. Study Design—We surveyed attitudes and practices among 163 neurologists and 372 psychiatrists. Results—24.9% of neurologists and 31.9% of psychiatrists had discussed prenatal GT with patients, but 95.3% didn’t feel comfortable discussing PGD; only 2.9% discussed it; and only 1.8% had patients ask about PGD. Most would refer for PGD for Huntington’s disease (HD) and Tay-Sachs, fewer for Cystic Fibrosis (CF), and fewer still for autism, Alzheimer’s (AD), or gender selection for family balancing; in each of these cases, psychiatrists > neurologists. Providers who’d refer for PGD for HD, CF, or gender selection differed from others in proportions of patients with insurance, were more likely to have undergone a GT themselves, and be concerned about discrimination. Conclusions—These data, the first to examine how neurologists and psychiatrists view PGD, suggest they don’t feel comfortable discussing PGD, but have strong views about its use. Potential PGD use is associated with concerns about discrimination, and less experience with GT. These data highlight needs for enhancing education about these technologies among various providers.

description: Background: Research has generally examined institutional review boards (IRBs) in isolation, but critical questions arise of how these entities fit into the larger institutional contexts in which they operate and what the implications may be. Methods: Semistructured interviews were conducted with leaders of IRBs from among the top 240 institutions receiving funding from the National Institutes of Health. Results: Interviewees felt that institutions may affect IRBs through both broad, indirect features (e.g., size, type of research, and culture of the institution), and more direct, IRB-related factors (e.g., amount of leadership and resource support for the IRB). Interviewees thought that institutional support of IRBs ranged from financial to nonfinancial, and direct to indirect, and that these institutional factors can mold amounts of IRB staff and education, audits, education of principal investigators (PIs), and tensions IRBs had to address. Respondents felt that these factors can in turn potentially affect IRB reviews of protocols and interactions with PIs. Within the complex systems of an institution, IRBs felt that PIs’ experiences and complaints about the IRB to institutional leaders may also shape how the institution related to the IRB. Conclusions: These data are the first to show how IRBs perceive themselves as working within the contexts of dynamic local institutional relationships and systems that pose challenges and tensions that can potentially affect critical aspects of IRB functioning. The findings have implications for practice, future research, and policy.

description: Preimplantation genetic diagnosis (PGD) is increasingly available, but how physicians view it is unclear. Internists are gatekeepers and sources of information, often treating disorders for which PGD is possible. This quantitative study surveyed 220 US internists, who were found to be divided. Many would recommend PGD for cystic fibrosis (CF; 33.7%), breast cancer (BRCA; 23.4%), familial adenomatous polyposis (FAP; 20.6%) and familial hypertrophic cardiomyopathy (19.9%), but few for social sex selection (5.2%); however, in each case, >50% were unsure. Of those surveyed, 4.9% have suggested PGD to patients. Only 7.1% felt qualified to answer patient questions about it. Internists who would refer for PGD had completed medical training less recently and, for CF, were more likely to have privately insured patients (P 50% were unsure. Of those surveyed, 4.9% have suggested PGD to patients. Only 7.1% felt qualified to answer patient questions. Internists who would refer for PGD completed medical training less recently and, for CF, were more likely to have privately insured patients and patients who reported genetic discrimination. Physicians more likely to refer for BRCA and FAP were less likely to have patients ask about genetic testing. This quantitative study suggests that internists often feel they have insufficient knowledge and may refer for PGD based on limited understanding. They view possible uses of PGD differently, partly reflecting varying ages of onset and disease treatability. Internists should be made aware of the potential benefit of PGD, but also be taught to refer patients, when appropriate, to clinical geneticists who could then refer the patient to an IVF/PGD team. These data thus have critical implications for training, research and practice.

description: We study the monolithic finite element method, based on the least-squares minimization principles for the solution of non-Newtonian fluids with non-isothermal effects. The least-squares functionals are balanced by the linear and nonlinear weighted functions and the residuals comprised of L2-norm only. The weighted functions are the function of viscosities and proved significant for optimal results. The lack of mass conservation is an important issue in LSFEM and is studied extensively for the diverse range of weighted functions. Therefore, we consider only inflow/outflow problems. We use the Krylov subspace linear solver, i.e. conjugate gradient method, with a multigrid method as a preconditioner. The SSOR-PCG is used as smoother for the multigrid method. The Gauss-Newton and fixed point methods are employed as nonlinear solvers. The LSFEM is investigated for two main types of fluids, i.e. Newtonian and non-Newtonian fluids. The stress-based first-order systems, named SVP formulations, are employed to investigate the Newtonian fluids. The different types of quadratic finite elements are used for the analysis purposes. The nonlinear Navier-Stokes problem is investigated for two mesh configurations for flow around cylinder problem. The coefficients of lift/drag, pressure difference, global mass conservation are analyzed. The comparison of linear and nonlinear solvers, based on iterations, is presented as well. The analysis of non-Newtonian fluids is divided into two parts, i.e. isothermal and non-isothermal. For the non-Newtonian fluids, we consider only Q2 finite elements for the discretization of unknown variables. The isothermal non-Newtonian fluids are investigated with SVP-based formulations. The power law and Cross law viscosity models are considered for investigations with different nonlinear weighted functions. We study the flow parameters for flow around cylinder problem along with the mass conservation for shear thinning and shear thickening fluids. To study the non-isothermal non-Newtonian fluids, we introduced a new first-order formulation which includes temperature and named it as SVPT formulation. The non-isothermal effects are obtained due to the additional viscous dissipation in the fluid flow and from the preheated source as well. The flow around cylinder problem is analyzed for a variety of flow parameters for Cross law fluids. It is shown that the MPCG solver generates very accurate results for the coupled and highly complex problems.

Given a relative homotopy class, a relation, and a generic almost complex structure we provide the moduli space of discs which have an injective point with the structure of a smooth manifold. Applications to the local behaviour are given and an adjunction inequality for singularities is derived. Moreover, we show that for a coordinate class of a monotone Lagrangian split torus generically the number of non-immersed holomorphic discs is even.

Discrimination

description: Though the US passed the Genetic Information Non‐Discrimination Act, many questions remain of how individuals confronting genetic disease view and experience possible discrimination. We interviewed, for 2 hours each, 64 individuals who had, or were at risk for, Huntington's Disease, breast cancer, or Alpha‐1 antitrypsin deficiency. Discrimination can be implicit, indirect and subtle, rather than explicit, direct and overt; and be hard to prove. Patients may be treated “differently” and unfairly, raising questions of how to define “discrimination”, and “appropriate accommodation”. Patients were often unclear and wary about legislation. Fears and experiences of discrimination can shape testing, treatment, and disclosure. Discrimination can be subjective, and take various forms. Searches for only objective evidence of it may be inherently difficult. Providers need to be aware of, and prepared to address, subtle and indirect discrimination; ambiguities, confusion and potential limitations concerning current legislation; and needs for education about these laws. Policies are needed to prevent discrimination in life, long‐term care, and disability insurance, not covered by GINA.

Egg donors

description: Egg donation continues to increase in popularity as part of assisted reproduction (1). Although short-term health effects of donation have been well studied, many unanswered questions remain about the long-term medical and psychological consequences for women who donate eggs. Studies of longer-term postdonation health effects have significant limitations, and are often retrospective, cross-sectional, or case studies.

description: The infinitesimal symmetry algebra of any Cartan geometry has maximum dimension realized by the flat model, but often this dimension drops significantly when considering non-flat geometries, so a gap phenomenon arises. For general (regular, normal) parabolic geometries of type (G,P), we use Tanaka theory to derive a universal upper bound on the submaximal symmetry dimension. We use Kostant's version of the Bott-Borel-Weil theorem to show that this bound is in fact sharp in almost all complex and split-real cases by exhibiting (abstract) models. We explicitly compute all submaximal symmetry dimensions when G is any complex or split-real simple Lie group.
description: 44 pages. In order to better emphasize our main results, we reorganized our manuscript and reduced excessive background material and some running examples. (Readers wishing more background can view the relevant sections in version 3.)

description: Motivated by applications in sociology, economy and medicine, we study variants of the Target Set Selection problem, first proposed by Kempe, Kleinberg and Tardos. In our scenario one is given a graph $G=(V,E)$, integer values $t(v)$ for each vertex $v$ (\emph{thresholds}), and the objective is to determine a small set of vertices (\emph{target set}) that activates a given number (or a given subset) of vertices of $G$ \emph{within} a prescribed number of rounds. The activation process in $G$ proceeds as follows: initially, at round 0, all vertices in the target set are activated; subsequently at each round $r\geq 1$ every vertex of $G$ becomes activated if at least $t(v)$ of its neighbors are already active by round $r-1$. It is known that the problem of finding a minimum cardinality Target Set that eventually activates the whole graph $G$ is hard to approximate to a factor better than $O(2^{\log^{1-ε}|V|})$. In this paper we give \emph{exact} polynomial time algorithms to find minimum cardinality Target Sets in graphs of bounded clique-width, and \emph{exact} linear time algorithms for trees.

description: A nonsingular localized static classical solution is constructed for standard Einstein gravity coupled to an $SO(3)\times SO(3)$ chiral model of scalars (Skyrme model). This solution corresponds to a spacetime defect and its construction proceeds in three steps. First, an \textit{Ansatz} is presented for a solution with nonsimply connected topology of the spacetime manifold. Second, an exact vacuum solution of the reduced field equations is obtained. Third, matter fields are included and a particular exact solution of the reduced field equations is found. The latter solution has a diverging total energy, but its existence at least demonstrates that a nonsingular defect-type solution having nonsimply connected topology is possible with nontrivial matter fields.

description: Institutional Review Boards (IRBs) can play vital roles in observing, monitoring, and responding to research integrity (RI) issues among researchers, yet many questions remain concerning whether, when, and in what ways these boards in fact adopt these roles. Increasingly, RI is being challenged due to many factors, yet the extent of violations, and institutional responses to these, remain unknown. As the amount and complexity of experiments on human participants, often funded by for-profit industry, mushrooms, scandals have occurred,1 posing dilemmas concerning how to best oversee research to protect these participants from harm.
On the Achievable Error Region of Physical Layer Authentication Techniques over Rayleigh Fading Channels

description: For a physical layer message authentication procedure based on the comparison of channel estimates obtained from the received messages, we focus on an outer bound on the type I/II error probability region. Channel estimates are modelled as multivariate Gaussian vectors, and we assume that the attacker has only some side information on the channel estimate, which he does not know directly. We derive the attacking strategy that provides the tightest bound on the error region, given the statistics of the side information. This turns out to be a zero mean, circularly symmetric Gaussian density whose correlation matrices may be obtained by solving a constrained optimization problem. We propose an iterative algorithm for its solution: Starting from the closed form solution of a relaxed problem, we obtain, by projection, an initial feasible solution; then, by an iterative procedure, we look for the fixed point solution of the problem. Numerical results show that for cases of interest the iterative approach converges, and perturbation analysis shows that the found solution is a local minimum.

description: Η παρούσα διπλωματική εργασία έχει ως στόχο να παρουσιάσει και να συγκρίνει τις τεχνικές διαφορές μεταξύ δύο μεθόδων σχεδιασμού ανατίναξης υπόγειων μετώπων μορφής στοάς, παράλληλης διάταξης διατρημάτων. Αυτή της κλασσικής Σουηδικής μεθόδου κατά Holmberg με μέθοδο προεκσκαφής των τεσσάρων τετραγώνων και της Νορβηγικής μεθόδου (N.T.N.U). Η Νορβηγική μέθοδος εκπονήθηκε στο τμήμα Πολιτικών Μηχανικών του Πολυτεχνείου της Νορβηγίας, στο πλαίσιο της διδακτορικής διατριβής του Shokrollah Zare για την απλοποίηση των υπολογιστικών διαδικασιών σχεδιασμού ανατίναξης υπόγειων μετώπων.

Τα αποτελέσματα της σύγκρισης των δύο μεθόδων θα διευκολύνουν τον εκάστοτε μηχανικό στην σωστή επιλογή μεθόδου ανάλογα με τις απαιτήσεις του έργου και τους στόχους που του έχει ανατεθεί (π.χ. για μέτωπα εξόρυξης ή για τεχνικά έργα). Διότι θα του δώσουν μια “εικόνα” για τα υπέρ και τα κατά της κάθε μεθόδου αλλά και τη δυνατότητα να προτείνει επιχειρήματα για τον λόγο επιλογής της κάθε μίας.
Ο τρόπος με τον οποίο εξήχθησαν τα αποτελέσματα, ήταν πρώτα με τον καθορισμό συγκεκριμένων σταθερών και παραμέτρων όπως για παράδειγμα οι διαστάσεις του θεωρητικού μετώπου, το μήκος διάτρησης, το διαμέτρημα των διατρητικών στελεχών κ.τ.λ., τον καθορισμό των εξεταζόμενων μεταβλητών και στην συνέχεια την επίλυση θεωρητικών παραδειγμάτων.
