description: In this work, we consider the target detection problem in a sensing architecture where the radar is aided by a reconfigurable intelligent surface (RIS), that can be modeled as an array of sub-wavelength small reflective elements capable of imposing a tunable phase shift to the impinging waves and, ultimately, of providing the radar with an additional echo of the target. A theoretical analysis is carried out for closely- and widely-spaced (with respect to the target) radar and RIS and for different beampattern configurations, and some examples are provided to show that large gains can be achieved by the considered detection architecture.

description: The aim of this study is to investigate the distribution and excitation of the methanol gas around Cep A and to describe the physical conditions of the region. In addition the large scale abundance distribution is determined in order to understand the morphology and kinematics of star forming regions in which methanol masers occur. The spatial distribution of the methanol is studied by mapping line emission, as well as the column density and excitation temperature, which are estimated using rotation diagrams. For a limited number of positions the parameters are checked with non-LTE models. Furthermore, the distribution of the methanol abundance is derived in comparison with archival dust continuum maps. Methanol is detected over a 0.3x0.15 pc area centred on the Cep A HW2 source, showing an outflow signature. Most of the gas can be characterized by a moderately warm rotation temperature (30-60K). At the central position two velocity components are detected with different excitation characteristics, the first related to the large-scale outflow. The second component, uniquely detected at the central location, is probably associated with the maser emission on much smaller scales of 2". Detailed analysis reveals that the highest densities and temperatures occur for these inner components. In the inner region the dust and gas are shown to have different physical parameters. Abundances of methanol in the range 10E-9 - 10E-7 are inferred, with the abundance peaking at the maser position. The geometry of the large-scale methanol is in accordance with previous determinations of the Cep A geometry, in particular those from methanol masers. The dynamical and chemical time-scales are consistent with the methanol originating from a single driving source associated with the HW2 object and the masers in its equatorial region.

Genome instability in multiple myeloma-associated DIS3 exonuclease domain mutants
Creators: name: Milbury, Karissa Lynn
Publisher: name: University of British Columbia
Year: 2018

description: Chromosome instability (CIN) is characterized by an increased rate of the unequal distribution of DNA between daughter cells. Such changes in chromosome structure or number can occur due to both mitotic defects leading to aneuploidy and DNA damage-induced chromosome rearrangements. Previous large-scale screens for CIN genes in the model organism Saccharomyces cerevisiae identified DIS3, which encodes a catalytic component of the core RNA exosome complex, as a novel CIN gene. Mutations in human DIS3 have been identified in roughly 11% of multiple myeloma (MM) cases. I sought to recapitulate MM-associated point mutations at conserved sites in yeast cells, in order to understand the mechanism of emergent CIN in MM. I have found that MM-associated DIS3 exonuclease mutations do increase the frequency of CIN. A temperature sensitive DIS3 mutant accumulates DNA:RNA hybrids, however analysis of DNA damage foci by microscopy revealed no increase in double-strand breaks in any of the tested strains. Yeast DIS3 exonuclease mutants experience growth retardation, temperature sensitivity, and an altered cell cycle. Microarray analysis of one MM mutant has additionally demonstrated downregulation of cell cycle components, consistent with the potential for mitotic defects, in addition of upregulation of a host of metabolic pathways. Further, genetic interaction profiling by synthetic genetic array indicates MM-associated DIS3 mutations synthetically interact with rRNA processing proteins, as well as a host of mitotic regulators and metabolic pathways, particularly those involved in spindle and kinetochore function. Further, I verify that DIS3 mutants have a functional spindle assembly checkpoint, and are in fact resistant to microtubule poisons. Finally, I discover that the fitness defects induced by these mutations can be abrogated through culturing on media containing only a non-fermentable carbon source, suggesting that growth on poor carbon sources may also rescue CIN. Together, these results demonstrate extensive phenotypic consequences of MM-associated point mutations in DIS3, and support a model for CIN in DIS3 mutants involving defects in mitotic progression.

description: The nuclear size effect on the one-loop self energy and vacuum polarization is evaluated for the 1s, 2s, 3s, 2p_{1/2}, and 2p_{3/2} states of hydrogen-like ions. The calculation is performed to all orders in the binding nuclear strength parameter Zα. Detailed comparison is made with previous all-order calculations and calculations based on the expansion in the parameter Zα. Extrapolation of the all-order numerical results obtained towards Z=1 provides results for the radiative nuclear size effect on the hydrogen Lamb shift.

description: We study the resilience of complex networks against attacks in which nodes are targeted intelligently, but where disabling a node has a cost to the attacker which depends on its degree. Attackers have to meet these costs with limited resources, which constrains their actions. A network's integrity is quantified in terms of the efficacy of the process that it supports. We calculate how the optimal attack strategy and the most attack-resistant network degree statistics depend on the node removal cost function and the attack resources. The resilience of networks against intelligent attacks is found to depend strongly on the node removal cost function faced by the attacker. In particular, if node removal costs increase sufficiently fast with the node degree, power law networks are found to be more resilient than Poissonian ones, even against optimized intelligent attacks.

title: DEPRECATED: LINKING PERFORMANCE REQUIREMENTS WITH PROCESS IMPROVEMENT ACTIONS FOR BUSINESS PROCESS RE-DESIGN
Creators: name: WOOD, CITA LORRAINE
Publisher: name: University of Plymouth
Year: 2002

description: This thesis presents research that extends current knowledge in the area of business process re-design, with a specific focus on the 'Make Product' process within manufacturing organisations. Current business process re-design approaches offer only limited guidance on the specific changes that can be made to a process when re-designing it to achieve the desired performance improvements and often overlook any strategically derived performance requirements when re-designing the process. Case experience suggests that practitioners do not consider the performance requirements of their business processes when re-designing them and that the actions they take to achieve performance improvements are not selected with regard to any strategically derived performance requirements. This exploratory research investigates whether relationships can be established between the changes that can be made to a process when re-designing it and the performance improvements gained by implementing those changes. It then questions whether those relationships can be used to help companies to select the appropriate process changes to implement in order to meet their specific performance requirements. Performance Requirements and process changes (Process Improvement Actions) were derived from the relevant literature and included in a questionnaire designed to ascertain the strength of relationships between them. The questionnaire was subject to preliminary and pilot testing to improve validation and reliability prior to being administered to international business process re-design 'experts'. Statistical analysis of the questionnaire data resulted in a ranked list of Process Improvement Actions for each of the Performance Requirements. These were presented in a format for inclusion in a process-based change handbook and enable the practitioner to set the agenda for the intervention and select the Process Improvement Actions on the basis of the Performance Requirements. The Performance Requirements should be derived from the strategy of the company or change programme so a strategic focus is maintained throughout re-design. It was also found that of the thirteen Process Improvement Actions included in the questionnaire just five are needed to achieve improvements in a majority (80%) of the performance requirements. This research showed that it is possible to establish links between Performance Requirements and Process Improvement Actions and according to successful validation by practitioners, against an accepted model, that these can be used for business process re-design, laying foundations for future research in the area.

description: We present observations of a major outburst at centimeter, millimeter, optical, X-ray, and gamma-ray wavelengths of the BL Lacertae object AO 0235+164. We analyze the timing of multi-waveband variations in the flux and linear polarization, as well as changes in Very Long Baseline Array (VLBA) images at 7mm with 0.15 milliarcsecond resolution. The association of the events at different wavebands is confirmed at high statistical significance by probability arguments and Monte-Carlo simulations. A series of sharp peaks in optical linear polarization, as well as a pronounced maximum in the 7 mm polarization of a superluminal jet knot, indicate rapid fluctuations in the degree of ordering of the magnetic field. These results lead us to conclude that the outburst occurred in the jet both in the quasi-stationary "core" and in the superluminal knot, both parsecs downstream of the supermassive black hole. We interpret the outburst as a consequence of the propagation of a disturbance, elongated along the line of sight by light-travel time delays, that passes through a standing recollimation shock in the core and propagates down the jet to create the superluminal knot. The multi-wavelength light curves vary together on long time-scales (months/years), but the correspondence is poorer on shorter time-scales. This, as well as the variability of the polarization and the dual location of the outburst, agrees with the expectations of a multi-zone emission model in which turbulence plays a major role in modulating the synchrotron and inverse Compton fluxes.

description: Abstract
Several parts of India have inadequate bearing capacity and may not support the weight of the superstructure by the weak soil alone. Soil reinforcing techniques can be used for in-situ soils as a viable building material for a variety of projects with reinforcing materials like geogrid, geocell, confinement, etc and these are extremely expensive. In order to reduce the cost of construction, alternate and local available waste materials are needed as sustainability is the key. The increasing use of plastic goods has led to new issues with waste management; hence these waste items can be used to enhance the geotechnical qualities of the soil to increase the soil's bearing capacity, which avoid disposal issues. In this study series of model tests are conducted with plastic bottles as reinforcement, using sand at varying densities, reinforcement layers and the distance between the base of footing to first reinforcement layer. It is observed that the parameter selected in the present study has increased the load carrying capacity up to 262.5% compared with unreinforced soil.

description: We investigate transport through nanoribbons in the presence of disorder scattering. We show that size quantization patterns are only present when SU(2) pseudospin symmetry is preserved. Symmetry breaking disorder renders transverse quantization invisible, which may provide an explanation for the necessity of suspending graphene nanoconstrictions to obtain size quantization signatures in very recent experiments. Employing a quasi-classical Monte-Carlo simulation, we are able to reproduce and explain key qualitative features of the full quantum-mechanical calculations.

Within this framework, we derive a generalization of the detailed fluctuation theorem, which is modified by the addition of a term that quantifies the change in uncertainty about the microscopic state of the system upon making measurements of physical observables during feedback. As an application, we extend two nonequilibrium work relations: the nonequilibrium work fluctuation theorem and the relative-entropy work relation.

description: Abstract
This study attempts to verify the determinants of brand equity of services based on consumers' perception of a banking service. The conceptual framework of this study is based on customer-based brand equity called the Brand Resonance model, which comprises six building blocks, namely, brand salience, brand performance, brand imagery, brand judgment, brand feelings and brand resonance. Factor analyses were conducted on all items measuring the six constructs and the results produced only five factors i.e. brand salience, brand performance, brand judgments, brand feelings and brand resonance as the determinants of brand equity of services. The reliability test on all these factors produced satisfactory reliability coefficients. Correlation analysis was also conducted on the study variables and the results indicate that there are strong, positive and significant relationships between brand performance and brand judgment, and between brand performance and brand feelings. Strong, positive and significant relationships are also found between brand performance and brand resonance, between brand judgment and brand resonance as well as between brand feelings and brand resonance. The multiple regression results show that only Brand Feelings, Brand Judgments and Brand Performance 1 have a significant influence on Brand Resonance.

description: Despite critics'ack and forth argument over the merits, or lack thereof, of a uniquely black theatre experience, black women playwrights, much like their male counterparts, were once wholly invisible to the white community. But what makes their invisibility unique is their absence in the black world and in literary scholarship. Unfortunately, modern scholarship has oftentimes dismissed these exceptionally powerful plays, cataloging them as poorly written and lacking stylistic and formal elements. It was only recently that they were included in a highly male-dominated history of African American theatre and art. The question of their use of sentimentality, however, remains unanswered.

Using a framework of the public voices of these black female playwrights, interwoven among a historical analysis of anti-slavery writing, lynching, and the ideologies that shaped American culture for both blacks and whites, I suggest that Angelina Grimke, Georgia Douglas Johnson, and Mary Church Terrell mimic the writings of both black and white female abolitionists, who used sentimentalism as a form of resistance and deconstruction. Furthermore, the goal of this thesis is to demonstrate that the rhetorical form of Grimke, Johnson, and Terrell represents a desire to reinvoke the spirit of the black matriarch, whose powerful presence encourages racial equality for black men and women, rewrites the signs of lynching, and redefines womanhood as an experience representative of all women. By positioning women and the family in the forefront of their dramas, these playwrights dismantle and restructure the horror that surrounds lynching.

I suggest that in these plays we see a shift not only in characters but in narrative action as well. The so-called "heroes" of the lynch rope are unmasked as criminals and murders. The victim is no longer a white woman or her womanhood. Instead, we see the suffering of black men, women, and children. The horror now becomes the destruction of the black family and the sanctified murder of black men. Through this literature, we are offered a different perspective from which to view the signs of lynching.

Our result for the optimally doped compound without induced SDW is in qualitative agreement with recent scanning tunneling microscopy experiment. We also propose that the main effect of the SDW on the vortex states is to reduce the intensity of the in-gap peak in the local density of states and transfer the spectral weight to form additional peaks outside the gap.

title: DEPRECATED: PROTEIN SYNTHESIS INHIBITION AND SHORT AND LONG TERM HABITUATION OF THE DORSAL ANTENNAE WITHDRAWAL RESPONSE IN HELIX ASPERSA
Creators: name: RAY, STEPHEN
Publisher: name: University of Plymouth
Year: 1988

description: The pharmacological disruption of memory by various protein synthesis inhibitory drugs (PSIs) has implicated protein synthesis as a requirement for long term learning but not for short. However, evidence derived from PSI research remains equivocal, with the apparent amnesic effects of PSIs being attributed to drug side-effects and general behavioural debilitations. Research reported in this thesis investigates the behavioural effects on short and long term habituation of the dorsal antennae withdrawal reflex in the snail (Helix aspersa) of three antibiotic drugs known to reversibly inhibit protein synthesis; anisomycin, actinomycin D, and puromycin. Initially, habituation was established as true learning in the snail and was demonstrated to be capable of retention for over 24 hours from one training session and over 6 months from a series of training sessions. The parametric characteristics of both short and long term habituation in the snail was established and found to be identical to those demonstrated in vertebrate habituation. Such characteristics were found to be different for short and long term habituation. Injection of PSIs showed no effect on short term habituation but disrupted long term habituation if PSI was active within a 'critical time window' during or for approximately 40 minutes after training. Later injections had no amnesic effect, and neither did injections 2 hours prior to training. The amnesic effects were demonstrated not to be attributable to drug side-effects by the development and application of a 'behavioural test battery' to screen general snail behaviour for drug induced debilitations at a variety of doses. Dose/amnesic effect relationships are also reported. Potentially confounding effects, such as, state dependent learning, and drug performance effects, were controlled out. The effects of the PSIs on short and long term habituation are then reported in terms of their effects on the established short and long term parametric characteristics of the learning. Drug injected snails showed normal short term parametric characteristics in training. However, in a long term retest drug treated snails also showed the parametric characteristics of short term habituation which demonstrated the degree of induced amnesia. The results are discussed in terms of a gene expression model of long term habituation and suggest that short and long term habituation are mediated by different processes. Short term habituation is protein synthesis independent and long term habituation is protein synthesis dependent.

description: Nonequilibrium quantum field theory is often used to derive an approximation for the evolution of number densities and asymmetries in astroparticle models when a more precise treatment of quantum thermal effects is required. This work presents an alternative framework using the zero-temperature quantum field theory, $S$-matrix unitarity, and classical Boltzmann equation as starting points leading to a set of rules for calculations of thermal corrections to reaction rates. Statistical factors due to on-shell intermediate states are obtained from the cuts of forward diagrams with multiple spectator lines. It turns out that it is equivalent to cutting closed diagrams on a cylindrical surface.

Young children, parents and technology : a case study exploring how the play choices of a 3 year old child relate to parental attitudes and behaviours around technology.
Creators: name: Adebar, Yvonne Kiefert
Publisher: name: University of British Columbia
Year: 2018

description: Today’s digital landscape is evolving more quickly than existing research about the effects of digital technology on the development, learning and family life of young children, particularly those under the age of five. As research suggests, there is a causal relationship between use of digital technology and the health and well-being of individuals. It is therefore important to come to an understanding of how digital behaviours are developed in the early years, a time of radical growth and learning with long term implications for the young child. Research suggests that the child’s development of attitudes and behaviours related to digital technology may be influenced by parental use of and attitudes about digital media as well as the structuring of the child’s experiences and environment. The purpose of this qualitative case study was to explore the question of how the play choices of a 3 year old boy relate to the behaviours and beliefs parents demonstrate in the home in regards to digital technology. Data collection included parent and child questionnaires as well as observations and documentation of the child’s play preferences when offered choices from traditional as well as digital materials. Results were examined using a thematic analysis to determine if a relationship between child choices and parental beliefs and practices is indicated.
Trophic Factors and Stem Cells for Promoting Recovery in Stroke

description: Stem cell therapy for stroke is in its initial stages as an option to restore lost neurological functions after stroke.
Objective:
To provide a comprehensive review of studies involving stem cells in stroke treatment and to highlight new evidence from the ongoing clinical trials.
Methodology:
We performed a systematic study of various published journals in online medical libraries using Pubmed, Sciencedirect, and hajournal. Evidence synthesis is done with specific search words of – stem cell therapy, stroke, trophic factor, neural progenitor cell, pathophysiology, mechanism of action, clinical trial and mesenchymal stem cell in various combinations. Emphasis was given to articles published in year 2000 and onwards.
Results:
Current research on stem cell therapy for stroke focuses on transplantation and endogenous neurogenesis of stem cells in brain. The sub-ventricular zone in the adult brain is identified as an endogenous resource of neuronal precursors that can be recruited to adjacent lesioned areas. Several factors can increase adult neurogenesis by stimulating formation or improving survival of new neurons, such as FGF-2, EGF, stem cell factor, erythropoietin, BDNF, caspase inhibitors, and anti-inflammatory drugs. Much of the beneficial effects of stem cell in stroke models are related to secretion of trophic factors.
Conclusion:
The complex pathophysiology involving various trophic factors, growth factor and gene modification in animal studies have showed promising result. Future research involving these trophic factors should open up new additional or clinically significant alternative for the treatment of stroke.

description: Non-destructive Schottky detectors are indispensable devices widely used in experiments at heavy-ion storage rings. In particular, they can be used to accurately determine the masses and lifetimes of short-lived exotic nuclear species. Single-ion sensitivity -- which enables highest sensitivity -- has been regularly achieved in the past utilizing resonant cavity detectors. Recent designs and analysis methods aim at pushing the limits of measurement accuracy by increasing the dimensionality of the acquired data, namely the position of the particle as well as the phase difference between several detectors. This work describes current methods and future perspectives of Schottky detection techniques focusing at their application for mass and lifetime measurements of the most rare and simultaneously short-lived radio nuclides.

description: In a sub-arcsec near-infrared survey of the Crab Nebula using the new Spartan Infrared Camera, we have found several knots with high surface brightness in the H_2 2.12 micron line and a very large H_2 2.12 micron to Br-gamma ratio. The brightest of these knots has an intensity ratio I(H_2 2.12 micron)/I(Br-gamma) = 18+/-9, which we show sets a lower limit on the ratio of masses in the molecular and recombination (i.e. ionized) zones M_mol / M_rec >/- 0.9, and a total molecular mass within this single knot M_mol >/- 5E-5 M_sun. We argue that the knot discussed here probably is able to emit so strongly in the 2.12 micron line because its physical conditions are better tuned for such emission than is the case in other filaments. It is unclear whether this knot has an unusually large M_mol / M_rec ratio, or if many other Crab filaments also have similar amounts of molecular gas which is not emitting because the physical conditions are not so well tuned.

Phase-contrast Magnetic Resonance (pc-MR) volumetric flow-rate (VFR) measurements were performed in cerebral arteries of a 51 years old woman with coexisting CoA, and five healthy volunteers. Numerical predictions of a number of relevant hemodynamic indices were performed in an IA located in sub-clinoid part of left internal carotid artery (ICA) of the patient. Computations were performed using Ansys®-CFX™ solver using the VFR values measured in the patient as boundary conditions (BCs). A second analysis was performed using the average VFR values measured in healthy volunteers. The VFR waveforms measured in the patient and healthy volunteers were compared followed by a comparison of the hemodynamic indices obtained using both approaches. The results are discussed in the background of relevant literature.
Results:
Mean flow-rates were increased by 27.1% to 54.9% (2.66–5.44 ml/sec) in the cerebral circulation of patients with CoA as compared to healthy volunteers (1.2–3.95 ml/sec). Velocities were increased inside the IA by 35–45%. An exponential rise of 650% was observed in the area affected by high wall shear stress (WSS>15Pa) when flow-rates specific to CoA were used as compared to population average flow-rates. Absolute values of space and time averaged WSS were increased by 65%. Whereas values of maximum pressure on the IA wall were increased by 15% the area of elevated pressure was actually decreased by 50%, reflecting a more focalized jet impingement within the IA of the CoA patient.
Conclusions:
IAs can develop in patients with CoA several years after the surgical repair. Cerebral flow-rates in CoA patients are significantly higher as compared to average flow-rates in healthy population. The increased supra-physiological WSS (>15Pa), OSI (>0.2) and focalized pressure may play an important role in the etiopathogenesis of IAs in patients with CoA.

description: This paper is concerned with the study of $M$-structures in spaces of polynomials. More precisely, we discuss for $E$ and $F$ Banach spaces, whether the class of weakly continuous on bounded sets $n$-homogeneous polynomials, $\mathcal P_w(^n E, F)$, is an $M$-ideal in the space of continuous $n$-homogeneous polynomials $\mathcal P(^n E, F)$. We show that there is some hope for this to happen only for a finite range of values of $n$. We establish sufficient conditions under which the problem has positive and negative answers and use the obtained results to study the particular cases when $E=\ell_p$ and $F=\ell_q$ or $F$ is a Lorentz sequence space $d(w,q)$. We extend to our setting the notion of property $(M)$ introduced by Kalton which allows us to lift $M$-structures from the linear to the vector-valued polynomial context. Also, when $\mathcal P_w(^n E, F)$ is an $M$-ideal in $\mathcal P(^n E, F)$ we prove a Bishop-Phelps type result for vector-valued polynomials and relate norm-attaining polynomials with farthest points and remotal sets.

description: Selective Mutism (SM) is a relatively rare phenomenon, typically arising in early childhood. However, the impact can be severe and widespread and without effective intervention, it can persist into adulthood. Despite this, the phenomenon is largely misunderstood, and access to support for children and their families and guidance for school staff and supporting professionals is scarce, delaying assessment and intervention. Research is also limited and largely consists of quantitative studies and clinical case studies, evaluating the impact of interventions, rather than exploring the views of those who have lived the phenomenon. This research aimed to provide parents with a unique opportunity to share their lived experience of understanding and supporting their child with SM. In particular, their experience of the onset and impact of SM, experience of support, particularly within their child’s educational setting, and how they have coped and maintained their own wellbeing. The study adopted a qualitative design with semi-structured interviews. Six parents with a child between 3- and 7-years-old with a diagnosis of SM were interviewed. The researcher adopted a critical realist epistemological stance and used Interpretative Phenomenological Analysis to interpret the data. Six superordinate themes were identified across the participants: ‘Complex Onset’, ‘Pervasive Impact’, ‘Available and Helpful Sources of Support’, ‘Challenges in Accessing Support’, ‘Parent Taking on the Role of an Advocate’, and ‘Parental Coping Strategies’. Parents attributed SM to a combination of biological and environmental factors and reported a detrimental impact on various aspects of their child’s life and on their own wellbeing. Access to support was inconsistent and dependent on the understanding of school staff and professionals and available resources. The parents appeared resilient, adopting various coping mechanisms. Through active dissemination, these findings have the potential to improve the understanding of SM and the practice of school staff and professionals, including Educational Psychologists.

description: Transport phenomena plays an important role in science and technology. In the wide variety of applications both advection and diffusion may appear. Regarding diffusion, for long times, different type of decay rates are possible for different non-equilibrium systems. After summarizing the existing solutions of the regular diffusion equation, we present not so well known solution derived from three different trial functions, as a key point we present a family of solutions for the case of infinite horizon. By this we tried to make a step toward understanding the different long time decays for different diffusive systems.

Leptomeningeal Collateral Response and Computed Tomographic Perfusion Mismatch in Acute Middle Cerebral Artery Occlusion
Creators: name: Zeenat Qureshi Stroke Institutes
Publisher: name: Zenodo
Year: 2023

description: To identify the relationship between the magnitude of leptomeningeal collaterals (LMC) on digital subtraction angiography (DSA) and regional cerebral blood volume (rCBV)/regional cerebral blood flow (rCBF) mismatch on computed tomography perfusion (CTP) in patients with acute middle cerebral artery (MCA) occlusion.
Design/Methods:
We reviewed the clinical records, and neuroimaging studies in consecutive patients with proximal MCA (M1-segment) and proximal branch (M2-segment) occlusion undergoing endovascular treatment following the demonstration of mismatch on CTP. DSA images acquired prior to the treatment were used to grade collateral flow from the anterior cerebral artery to the MCA on a scale ranging from 1 to 5, based on retrograde reconstitution of MCA segments in the late arterial phase. CTP images were reviewed and rCBV/rCBF mismatch was categorized as minor (≤ 1/3 of MCA territory), moderate (1/3–2/3 of MCA territory), or severe (> 2/3 to complete territory). Statistical association was assessed using Pearson exact test.
Results:
A total of sixteen patients were studied (10 were men; mean age of 69 years). Mean time from symptom onset to CTP was 146 minutes. Patients with M1-segment occlusion (n=10) had more severe rCBV/rCBF mismatch compared to patients with M2-segment occlusion (p=0.016). There was no association between the magnitude of LMC and severity of rCBV/rCBF mismatch on CTP.
Conclusions/Relevance:
The magnitude of LMC on DSA does not correlate with the severity of rCBV/rCBF mismatch in patients with MCA occlusion. This result suggests that additional factors, such as micro vascular failure, may contribute to altered cerebral perfusion.

description: Diffraction in time (DIT) is a fundamental phenomenon in quantum dynamics due to time-dependent obstacles and slits. It is formally analogous to diffraction of light, and is expected to play an increasing role to design coherent matter wave sources, as in the atom laser, to analyze time-of-flight information and emission from ultrafast pulsed excitations, and in applications of coherent matter waves in integrated atom-optical circuits. We demonstrate that DIT emerges robustly in quantum waves emitted by an exponentially decaying source and provide a simple explanation of the phenomenon, as an interference of two characteristic velocities. This allows for its controllability and optimization.
