description: This paper considers weak supercyclicity for bounded linear operators on a normed space. On the one hand, weak supercyclicity is investigated for classes of Hilbert-space operators: (i) self-adjoint operators are not weakly supercyclic, (ii) diagonalizable operators are not weakly l-sequentially supercyclic, and (iii) weak l-sequential supercyclicity is preserved between a unitary operator and its adjoint. On the other hand, weak supercyclicity is investigated for classes of normed-space operators: (iv) the point spectrum of the normed-space adjoint of a power bounded supercyclic operator is either empty or is a singleton in the open unit disk, (v) weak l-sequential supercyclicity coincides with supercyclicity for compact operators, and (vi) every compact weakly l-sequentially supercyclic operator is quasinilpotent.
Elucidating the Role of Migratory Fetal Cells Found in the Lungs of Pregnant Woman

Publisher: name: University of Illinois at Chicago
Year: 2024

description: ABSTRACT
Rationale and Goal: During pregnancy, fetal cells (FCs) have been known to enter the maternal circulation where they can then migrate to various maternal organs, interacting with the maternal microenvironment. What remains unclear, however, is the cellular identity and molecular characteristics of these migratory fetal cells. The goal of my research is to identify and characterize the migratory FCs that home to the maternal lung, and explore their angiogenic activities and potential to mediate organ repair by adapting an endothelial cell-like phenotype.

Methods and Results: To identify and characterize these putative regenerative FCs, I set up timed breeding experiments using a RosamT/mG+ male reporter mouse and crossed it with wild-type (WT) C57BL6 female mouse. After timed matings, vascularized organs were harvested late gestation, and stained sections subjected to high-resolution epifluorescence microscopy examining for co-localization between RFP+ fetal cells and endothelial-specific markers CD31 and VE-Cadherin. In order to confirm the presence of FC gene and endothelial lineage markers, we performed PCR by using FC-specific PCR primers to amplify gene products, prepared from the maternal vascular tissues. PCR confirmed the presence of FC gene in the pregnant mothers’ lung tissue. Furthermore, live microscopy analysis of thin cryosections showed the presence of FCs in the pregnant mouse vascular tissues, while control virgin female mice did not. After completing whole transcriptome sequencing, we have additionally identified several lncRNA transcriptional targets that may contribute to the notable increase in Flk1 expression within the maternal lung during Pregnancy.

Summary: Our results indicate the presence of RosamT/mG+ FCs in maternal tissues. Importantly, a subset of these FCs incorporated into CD31+ vascular structures. Additionally, I have identified a subset of candidate lncRNA in maternal lung tissue which are likely to be expressed as an adaptive response.

description: The Eigenstate Thermalization Hypothesis (ETH) implies a form for the matrix elements of local operators between eigenstates of the Hamiltonian, expected to be valid for chaotic systems. Another signal of chaos is a positive Lyapunov exponent, defined on the basis of Loschmidt echo or out-of-time-order correlators. For this exponent to be positive, correlations between matrix elements unrelated by symmetry, usually neglected, have to exist. The same is true for the peak of the dynamic heterogeneity length, relevant for systems with slow dynamics. These correlations, as well as those between elements of different operators, are encompassed in a generalized form of ETH.

description: In this paper, we deal with a calculus system SLCD (Syllogistic Logic with Carroll Diagrams), which gives a formal approach to logical reasoning with diagrams, for representations of the fundamental Aristotelian categorical propositions and show that they are closed under the syllogistic criterion of inference which is the deletion of middle term. Therefore, it is implemented to let the formalism comprise synchronically bilateral and trilateral diagrammatical appearance and a naive algorithmic nature. And also, there is no need specific knowledge or exclusive ability to understand as well as to use it. Consequently, we give an effective algorithm used to determine whether a syllogistic reasoning valid or not by using SLCD.

description: On-chip buses are typically designed to meet performance constraints at worst-case conditions, including process corner, temperature, IR-drop, and neighboring net switching pattern. This can result in significant performance slack at more typical operating conditions. In this paper, we propose a dynamic voltage scaling (DVS) technique for buses, based on a double sampling latch which can detect and correct for delay errors without the need for retransmission. The proposed approach recovers the available slack at non-worst-case operating points through more aggressive voltage scaling and tracks changing conditions by monitoring the error recovery rate. Voltage margins needed in traditional designs to accommodate worst-case performance conditions are therefore eliminated, resulting in a significant improvement in energy efficiency. The approach was implemented for a 6mm memory read bus operating at 1.5GHz (0.13 $μ$m technology node) and was simulated for a number of benchmark programs. Even at the worst-case process and environment conditions, energy gains of up to 17% are achieved, with error recovery rates under 2.3%. At more typical process and environment conditions, energy gains range from 35% to 45%, with a performance degradation under 2%. An analysis of optimum interconnect architectures for maximizing energy gains with this approach shows that the proposed approach performs well with technology scaling.

description: In this paper, we develop a new novel data structure called SH-Struct (Soft-Hyperlinked Structure) which mines the complete frequent itemset using SH-Mine algorithm. This algorithm enables frequent pattern mining with different supports. SH-Struct is based on creating SH-Tree which extends the idea of H-Struct to improvise storage compression and allow very fast frequent pattern mining. The algorithm has been tested extensively with various datasets and the experimental analysis shows that it outperforms FP-growth (Frequent Pattern growth) algorithm in terms of space and time payoffs.

description: Theories with spontaneous local Lorentz and diffeomorphism violation contain massless Nambu-Goldstone modes, which arise as field excitations in the minimum of the symmetry-breaking potential. If the shape of the potential also allows excitations above the minimum, then an alternative gravitational Higgs mechanism can occur in which massive modes involving the metric appear. The origin and basic properties of the massive modes are addressed in the general context involving an arbitrary tensor vacuum value. Special attention is given to the case of bumblebee models, which are gravitationally coupled vector theories with spontaneous local Lorentz and diffeomorphism violation. Mode expansions are presented in both local and spacetime frames, revealing the Nambu-Goldstone and massive modes via decomposition of the metric and bumblebee fields, and the associated symmetry properties and gauge fixing are discussed. The class of bumblebee models with kinetic terms of the Maxwell form is used as a focus for more detailed study. The nature of the associated conservation laws and the interpretation as a candidate alternative to Einstein-Maxwell theory are investigated. Explicit examples involving smooth and Lagrange-multiplier potentials are studied to illustrate features of the massive modes, including their origin, nature, dispersion laws, and effects on gravitational interactions. In the weak static limit, the massive mode and Lagrange-multiplier fields are found to modify the Newton and Coulomb potentials. The nature and implications of these modifications are examined.

description: La necessità di giustificare gli investimenti fatti in R&D e le diverse forme che questa necessità ha assunto in Europa e nel nostro Paese (confusione rispetto alle finalità della ricerca, eccesso di burocratizzazione, esasperazione della valutazione quantitativa, uso indiscriminato e spesso scorretto degli indicatori bibliometrici) hanno condotto a comportamenti e pratiche da parte dei ricercatori spesso scorrette. Nell’epoca del publish or perish il tempo a disposizione per il controllo dei dati e dei risultati è sempre meno, così come quello da dedicare alla revisione dei lavori dei colleghi, e spesso preso nei complessi ingranaggi degli avanzamenti di carriera, dei finanziamenti dei progetti, della ricerca del prestigio, il ricercatore sembra dimenticare quale siano gli obiettivi. La EC fa un richiamo esplicito ai ricercatori e alle istituzioni per un ritorno all’etica della ricerca e nel suo programma Science with and for Society richiama il concetto di Ricerca responsabile. Una delle azioni attraverso le quali realizzare la ricerca responsabile è certamente l’Open Access, come modalità di disseminazione della ricerca ma anche e soprattutto della trasparenza dei processi (e responsabilità) di valutazione. La finalità ultima è quella di una ricerca che corrisponda ai bisogni e alle aspettative della società, che si fondi sulla collaborazione più che sulla competizione e che individui con chiarezza i suoi reali interlocutori.

description: The objective of the work presented here is to develop a low cost active above knee prosthetic device exploiting bipedal robotics technology which will work utilizing the available biological motor control circuit properly integrated with a Central Pattern Generator (CPG) based control scheme. The approach is completely different from the existing Active Prosthetic devices, designed primarily as standalone systems utilizing multiple sensors and embedded rigid control schemes. In this research, first we designed a fuzzy logic based methodology for offering suitable gait pattern for an amputee, followed by formulating a suitable algorithm for designing a CPG, based on Rayleigh’s oscillator. An indigenous probe, Humanoid Gait Oscillator Detector (HGOD) has been designed for capturing gait patterns from various individuals of different height, weight and age. These data are used to design a Fuzzy inference system which generates most suitable gait pattern for an amputee. The output of the Fuzzy inference system is used for designing a CPG best suitable for the amputee. We then developed a CPG based control scheme for calculating the damping profile in real time for maneuvering a prosthetic device called AMAL (Adaptive Modular Active Leg). Also a number of simulation results are presented which show the stable behavior of knee and hip angles and determine the stable limit cycles of the network.

description: The problem of determining lower bounds for the energy cost of a given nanoscale design is addressed via a complexity theory-based approach. This paper provides a theoretical framework that is able to assess the trade-offs existing in nanoscale designs between the amount of redundancy needed for a given level of resilience to errors and the associated energy cost. Circuit size, logic depth and error resilience are analyzed and brought together in a theoretical framework that can be seamlessly integrated with automated synthesis tools and can guide the design process of nanoscale systems comprised of failure prone devices. The impact of redundancy addition on the switching energy and its relationship with leakage energy is modeled in detail. Results show that 99% error resilience is possible for fault-tolerant designs, but at the expense of at least 40% more energy if individual gates fail independently with probability of 1%.

description: Human knee plays the most important role in Human Walking cycle. It balances the force exerted by human weight on it by applying appropriate torque for resisting the knee movement, which prevents human from buckling down. A controller has been designed for above knee Active prosthetic leg for controlling the damping forces while human walk. It could control the amount of damping applied at the knee joint to resist the knee movement. Certain sensors are use to take the real time values of the knee angle and the knee moment. Later those sensor values are processed to purify the errors introduced while reading sensors. Purifies values are then subjected to neural network base classifier for phase identification. Once the phase of the Human gait cycle is identified then a particulate equation is selected from the set of equations relevant to that particular phase calculating the damping values. The selected equation is equated with the help of sensor values captured and the calculated damping value is sent to the Damping device.

Incorporation of Velocity-dependent Restitution Coefficient and Particle Surface Friction into Kinetic Theory for Modeling Granular Flow Cooling

description: Kinetic theory (KT) has been successfully used to model rapid granular flows in which particle interactions are frictionless and near elastic. However, it fails when particle interactions become frictional and inelastic. For example, the KT is not able to accurately predict the free cooling process of a vibrated granular medium that consists of inelastic frictional particles under microgravity. The main reason that the classical KT fails to model these flows is due to its inability to account for the particle surface friction and its inelastic behavior, which are the two most important factors that need be considered in modeling collisional granular flows. In this study, we have modified the KT model that is able to incorporate these two factors. The inelasticity of a particle is considered by establishing a velocity-dependent expression for the restitution coefficient based on many experimental studies found in the literature, and the particle friction effect is included by using a tangential restitution coefficient that is related to the particle friction coefficient. Theoretical predictions of the free cooling process by the classical KT and the improved KT are compared with the experimental results from a study conducted on an airplane undergoing parabolic flights without the influence of gravity [Y. Grasselli, G. Bossis, and G. Goutallier, EPL (Europhysics Letters) 86, 60007 (2009)]. Our results show that both the velocity- dependent restitution coefficient and the particle surface friction are important in predicting the free cooling process of granular flows; the modified KT model that integrates these two factors is able to improve the simulation results and led to a better agreement with the experimental results.

description: In this paper we investigate radiation by an accelerated quark in a strongly coupled gauge theory via AdS/CFT correspondence. According to AdS/CFT dictionary, we can read off energy density or energy flux of the radiation from asymptotic gravitational field in AdS bulk sourced by an accelerated string trailing behind the quark. In the case of an oscillating quark with frequency $Ω$, we show that the time averaged energy density is asymptotically isotropic and it falls off as $(g_{\text{YM}}^2 N)^{1/2} Ω^4/R^{2}$ with distance $R$ from the source. In a toy model of a scattered quark by an external field, we simply estimate Poynting vector by the bremsstrahlung radiation and show that the energy flux is anisotropic outgoing radiation. Based on these investigations, we discuss the properties of strongly coupled gauge theory radiation in comparison with electromagnetic radiation.

description: Spectroscopic observations made by the Extreme Ultraviolet Variability Experiment (EVE) on board the Solar Dynamics Observatory (SDO) during the 2012 March 7 X5.4-class flare (SOL2012-03-07T00:07) are analyzed for signatures of the non-Maxwellian kappa-distributions. Observed spectra were averaged over 1 minute to increase photon statistics in weaker lines and the pre-flare spectrum was subtracted. Synthetic line intensities for the kappa-distributions are calculated using the KAPPA database. We find strong departures (kappa < 2) during the early and impulsive phases of the flare, with subsequent thermalization of the flare plasma during the gradual phase. If the temperatures are diagnosed from a single line ratio, the results are strongly dependent on the value of kappa. For kappa=2, we find temperatures about a factor of two higher than the commonly used Maxwellian ones. The non-Maxwellian effects could also cause the temperatures diagnosed from line ratios and from the ratio of GOES X-ray channels to be different. Multithermal analysis reveals the plasma to be strongly multithermal at all times with flat DEMs. For lower kappa, the DEM_kappa are shifted towards higher temperatures. The only parameter that is nearly independent of kappa is electron density, where we find log(N_e) $\approx$ 11.5 almost independently of time. We conclude that the non-Maxwellian effects are important and should be taken into account when analyzing solar flare observations, including spectroscopic and imaging ones.

description: As Moore's Law continues to fuel the ability to build ever increasingly complex system-on-chips (SoCs), achieving performance goals is rising as a critical challenge to completing designs. In particular, the system interconnect must efficiently service a diverse set of data flows with widely ranging quality-of-service (QoS) requirements. However, the known solutions for off-chip interconnects such as large-scale networks are not necessarily applicable to the on-chip environment. Latency and memory constraints for on-chip interconnects are quite different from larger-scale interconnects. This paper introduces a novel on-chip interconnect arbitration scheme. We show how this scheme can be distributed across a chip for high-speed implementation. We compare the performance of the arbitration scheme with other known interconnect arbitration schemes. Existing schemes typically focus heavily on either low latency of service for some initiators, or alternatively on guaranteed bandwidth delivery for other initiators. Our scheme allows service latency on some initiators to be traded off smoothly against jitter bounds on other initiators, while still delivering bandwidth guarantees. This scheme is a subset of the QoS controls that are available in the SonicsMX? (SMX) product.

Behavior of axion-like particles in smoothed out domain-like magnetic fields

description: Basically, in certain circumstances axion-like particles (ALPs) substantially enhance the photon survival probability $P_{γ\to γ} ({\cal E})$ of a beam emitted by a far-away source through the mechanism of photon-ALP oscillation (${\cal E}$ denotes the energy). But in order for this to work, an external magnetic field ${\bf B}$ must be present. In several cases ${\bf B}$ is modeled as a domain-like network with `sharp edges': all domains have the same size $L_{\rm dom}$ (set by the ${\bf B}$ coherence length) and the same strength B, but the direction of ${\bf B}$ changes randomly and abruptly from one domain to the next. It is obviously a highly mathematical idealization wherein the components of ${\bf B}$ are discontinuous across the edges (whence the name sharp edges). It is therefore highly desirable to go a step further, and to find out what happens when the edges are smoothed out, namely when the abrupt change of ${\bf B}$ is replaced by a smooth one. Moreover, this step becomes compelling when the photon-ALP oscillation length $l_{\rm osc}$ turns out to be comparable to -- or smaller than -- $L_{\rm dom}$, because in this case the photon survival probability $P_{γ\to γ} ({\cal E})$ critically depends on the domain shape. In the present paper we propose a smoothed out version of the previous domain-like structure of ${\bf B}$ which incorporates the above changes, and we work out its implications. Even in the present case we are able to solve analytically and exactly the photon/ALP beam propagation equation inside a single smoothed-out domain, thereby evaluating the corresponding $P_{γ\to γ} ({\cal E})$ exactly. Our results is of particular importance in view of the new generation of gamma-ray detectors, since in such a situation $l_{\rm osc} \lesssim L_{\rm dom}$ occurs just above the TeV scale.

description: We describe ongoing efforts towards developing language resources for a transnational digital government project aimed at applying information technology (IT) to a problem of international concern: detecting and monitoring activities related to the transnational movement of illicit drugs. The project seeks to support information sharing, coordination and collaboration among government agencies within a country and across national boundaries by combining a variety of technologies including a distributed query processor with form-based and conversational user interfaces, a language translation system, an event server for event filtering and notification, and an event-trigger-rule server. The prototype system is being developed by U.S. universities in collaboration with an international agency and with universities and government agencies in Belize and the Dominican Republic. This paper focuses on the linguistic resources and their use in Example-Based Machine Translation (EBMT). We are in the process of developing an English- Spanish parallel corpus, focused on the domain of information elicited and used at border crossings, to fuel the EBMT system. While significant parallel corpora are available for these two languages in the newswire domain, they were found to be of very limited use for the border crossings application, spurring the need to develop our own resources.

description: The research undertaken in this study is on the prediction of friction and efficiency of spur gear meshing conjunctions in Formula 1 (F1) motorsport transmissions. Improving the efficiency of the vehicle is a massive undertaking with opportunities the lie throughout the powertrain. The transmission of the vehicle is a key area in which contributions to improving efficiency can be made. Particularly with the transmission of high loads, small variation in gear mesh efficiency scale up and can have a significant effect on the amount of power at the gearbox exit.This study presents an analysis of the various drivers of meshing contact efficiency specific to the high load and the compact gears common to this application. This analysis has been conducted using a developed semi-analytical tool which is a combination of modular quasi-static and dynamic components which when integrated allow for the appropriate consideration of gear geometry, lubricant rheology, gear and shaft flexibility, and the dynamic loading conditions of F1 racing drive cycles. Using the developed techniques, this thesis focuses on (a) the behaviour of meshing gear teeth under high loading conditions, (b) the effects of tooth profile and lead modifications present in current design iterations for purposes other than friction reduction, and (c) the effects of gear and shaft flexible dynamics and contact friction damping and efficiency predictions.

description: Conventional software specifications and reasoning based on such specifications do not accommodate uncertainty in the specifications, nor do they support the informal, subjective sorts of reasoning that many people use when making decisions about complex systems. We propose a notation for representing specifications in which attributes have different levels of confidence and we discuss ways that uncertain information can contribute usefully to software decisions.

description: The neutron-rich carbon isotopes 19,17C have been investigated via proton inelastic scattering on a liquid hydrogen target at 70 MeV/nucleon. The invariant mass method in inverse kinematics was employed to reconstruct the energy spectrum, in which fast neutrons and charged fragments were detected in coincidence using a neutron hodoscope and a dipole magnet system. A peak has been observed with an excitation energy of 1.46(10) MeV in 19C, while three peaks with energies of 2.20(3), 3.05(3), and 6.13(9) MeV have been observed in 17C. Deduced cross sections are compared with microscopic DWBA calculations based on p-sd shell model wave functions and modern nucleon-nucleus optical potentials. Jpi assignments are made for the four observed states as well as the ground states of both nuclei.

description: Variable selection is central to high-dimensional data analysis, and various algorithms have been developed. Ideally, a variable selection algorithm shall be flexible, scalable, and with theoretical guarantee, yet most existing algorithms cannot attain these properties at the same time. In this article, a three-step variable selection algorithm is developed, involving kernel-based estimation of the regression function and its gradient functions as well as a hard thresholding. Its key advantage is that it assumes no explicit model assumption, admits general predictor effects, allows for scalable computation, and attains desirable asymptotic sparsistency. The proposed algorithm can be adapted to any reproducing kernel Hilbert space (RKHS) with different kernel functions, and can be extended to interaction selection with slight modification. Its computational cost is only linear in the data dimension, and can be further improved through parallel computing. The sparsistency of the proposed algorithm is established for general RKHS under mild conditions, including linear and Gaussian kernels as special cases. Its effectiveness is also supported by a variety of simulated and real examples.

Disponibilità pubblica dei risultati scientifici versus clausole di segretezza previste in convenzioni di privati con le Università

description: Il tema del possibile conflitto tra il principio della disponibilità pubblica dei risultati scientifici e le clausole di segretezza previste nelle intese circa ricerche universitarie svolte per privati non è nuovo. Diviene oggi più rilevante perché, per gli Atenei, i finanziamenti “finalizzati” da privati, che rappresentavano nel 2000 meno del 14% rispetto al totale dei fondi ministeriali (FFO + “finalizzati” MIUR), hanno registrato in dieci anni un peso più che raddoppiato; inoltre tale presenza incide sugli stessi criteri di ripartizione del FFO. Nel presente intervento si presenta il risultato di una indagine, tuttora parziale, circa le modalità con le quali il tema viene toccato nei Codici Etici delle Università, e si suggeriscono sia approfondimenti conoscitivi, sia le possibili linee di una strategia istituzionale.

description: Abstract

The most prevalent thyroid gland condition is hypothyroidism which occurs when the thyroid's follicular cells are unable to produce enough thyroid hormones (THs) needed for body to function normally. Tetraiodothyronine (thyroxine), T4 and tri-iodothyronine (T3) are the two fundamental hormones produced by the thyroid gland (TG).THs are basically responsible for controlling the body’s metabolism. Iodine is a major contributor to the global rise in thyroid-related illnesses. Additionally, many clinical manifestations, indications, and symptoms that the patients showed were examined, and the condition was established in relation to those symptoms. This cross sectional study has been quantitatively carried out and depends on a method of statistical data analysis. This cross-sectional study was carried out over a period of one year from July 2019 to November 2020. This case study conducted at two famous hospitals of Jamshoro namely LUMHS and NIMRA. Total participants were 105. Sampling was random; samples were males, females and children. The study has been conducted to analyze the hypothyroid patients coming from various parts of Sindh at OPDs of NIMRA and LUMHS who have been severely affected with other disorders as well. The study involved special designed questionnaire and laboratory test reports for the purpose of analyzing the pure patients of hypothyroidism. Thyroid function test (TFT) was done using enzyme-linked immunoassay (ELISA) techniques, Radioimmunoassay (RIA) test kits.
Applying UML and MDA to Real Systems Design

description: Traditionally system design has been made from a black box/functionality only perspective which forces the developer to concentrate on how the functionality can be decomposed and recomposed into so called components. While this technique is well established and well known it does suffer fromsome drawbacks; namely that the systems produced can often be forced into certain, incompatible architectures, difficult to maintain or reuse and the code itself difficult to debug. Now that ideas such as the OMG's Model Based Architecture (MDA) or Model Based Engineering (MBE) and the ubiquitous modelling language UML are being used (allegedly) and desired we face a number of challenges to existing techniques.

description: Many embedded systems have high safety and dependability requirements, which makes ensuring software robustness a top priority in these systems. As embedded computer systems become more complex and incorporate increasing functionality, their software systems become increasingly more difficult to design, build, and maintain. One approach to achieving software robustness is graceful degradation. However, graceful degradation is a difficult property to define or construct. Traditional hardware redundancy is not enough to achieve software safety and dependability. The system's software architecture may be the key to building graceful degradation into a software system. This paper describes a proposal for a software architecture that may enhance graceful degradation for an example elevator control system, and discussion about implementing and evaluating the architecture.

description: We present a noncommutative extension of Quantum Cosmology and study the Kantowski-Sachs (KS) cosmological model requiring that the two scale factors of the KS metric, the coordinates of the system, and their conjugate canonical momenta do not commute. Through the ADM formalism, we obtain the Wheeler-DeWitt (WDW) equation for the noncommutative system. The Seiberg-Witten map is used to transform the noncommutative equation into a commutative one, i.e. into an equation with commutative variables, which depend on the noncommutative parameters, $θ$ and $η$. Numerical solutions are found both for the classical and the quantum formulations of the system. These solutions are used to characterize the dynamics and the state of the universe. From the classical solutions we obtain the behavior of quantities such as the volume expansion, the shear and the characteristic volume. However the analysis of these quantities does not lead to any restriction on the value of the noncommutative parameters, $θ$ and $η$. On the other hand, for the quantum system, one can obtain, via the numerical solution of the WDW equation, the wave function of the universe both for commutative as well as for the noncommutative models. Interestingly, we find that the existence of suitable solutions of the WDW equation imposes bounds on the values of the noncommutative parameters. Moreover, the noncommutativity in the momenta leads to damping of the wave function implying that this noncommutativity can be of relevance for the selection of possible initial states of the early universe.
