Abstract:
Given a hyper BCK-algebra (H, ∗, 0), each of the families BL(H) = {LH(A) : ∅ 6=A ⊆ H} and BR(H) = {RH(A) : ∅ 6= A ⊆ H} forms a base for some topology on H, where LH(A) = {x ∈ H : x a, ∀a ∈ A} and RH(A) = {x ∈ H : a x, ∀a ∈ A} for any subset A of H. In this paper, we determine the bases of the topologies induced by the hyper sum H1 ⊕ H2 and hyper product H1 × H2, where (H1, ∗1, 01) and (H2, ∗2, 02) are two hyper BCK-algebras.

Abstract:
ABSTRACTThe X-linked hyper-immunoglobulin M syndrome (HIGM-1) is a rare genetic disorder characterized by elevated serum IgM levels and low to undetectable levels of serum IgG, IgA and IgE. These patients characteristically present with recurrent sinopulmonary infections and recurrent diarrhea. They also have high susceptibility for Pneumocystis jiroveci (PJ) pneumonia. Herein, we report a case of HGM-1 in a 5-year-old boy who presented with bronchiectasis and, possibly, PJ pneumonia. The diagnosis was established on the basis of clinical features, immune profile, whole blood flow cytometry and history of two male sibling's death due to recurrent pneumonia and diarrhea.

Abstract:
A series of direct-measuring skin friction gages were developed for a high-speed, high-temperature environment of the turbulent boundary layer in flows such as that in supersonic combustion ramjet (scramjet) engines, with a progression from free-jet ground tests to a design for an actual hypersonic scramjet-integrated flight vehicle. The designs were non-nulling, with a sensing head that was flush with the model wall and surrounded by a small gap. Thus, the shear force due to the flow along the wall deflects the head, inducing a measurable strain. Strain gages were used to detect the strain. The gages were statically calibrated using a direct force method. The designs were verified by testing in a well-documented Mach 2.4 cold flow. Results of the cold-flow tests were repeatable and within 15% of the value of Cf estimated from simple theory. The first gage design incorporated a cantilever beam with semiconductor strain gages to sense the shear on the floating head. Cooling water was routed both internally and around the external housing in order to control the temperature of the strain gages. This first gage was installed and tested in a rocket-based-combined-cycle (RBCC) engine model operating in the scramjet mode. The free-jet facility provided a Mach 6.4 flow with P0 = 1350 psia (9310 kPa) and T0 = 2800 °R (1555 °K). Local wall temperatures were measured between 850 and 900 °R (472-500 °K). Output from the RBCC scramjet tests was reasonable and repeatable. A second skin friction gage was designed for and tested in a wind tunnel model of the Hyper-X flight vehicle scramjet engine. These unsuccessful tests revealed the need for a radically different skin friction gage design. The third and final skin friction gage was specifically developed to be installed on the Hyper-X flight vehicle. Rather than the cantilever beam and semiconductor strain gages, the third skin friction gage made use of a flexure ring and metal foil strain gages to sense the shear. The water-cooling and oil-fill used on the previous skin friction sensors were eliminated. It was qualified for flight through a rigorous series of environmental tests, including pressure, temperature, vibration, and heat flux tests. Finally, the third skin friction gage was tested in the Hyper-X Engine Model (HXEM), a full-scale-partial-width wind tunnel model of the flight vehicle engine. These tests were conducted at Mach 6.5 enthalpy with P0 = 555 psia (3827 kPa) and h0 = 900 Btu/lbm in a freejet facility. The successful testing in the wind tunnel scramjet model provided the final verification of the gage before installation in the flight vehicle engine. The development, testing, and results of all three skin friction gages are discussed.

Abstract:
Advances in computer automation and control, compact and portable x-ray sources, and reliable and efficient detector systems over the last ten years have allowed X-Ray Determination of Residual Stress (XRDRS) measurements to become a viable method of evaluating the state of stress in metals, alloys, and ceramics. However, problems associated with incorrect XRDRS equipment operation and poor experimental technique are prevalent, necessitating better operator training and education. Therefore, an interactive computer workstation, called RS/hyper, was developed to lead the operator towards correct operating procedures and reliable experimental technique. RS/hyper teaches the operator proper machine setup, machine maintenance, radiation safety, experimental technique, theoretical understanding, and provides limited data evaluation. Graphical aids are used extensively to avoid confusion and misinterpretation during the learning process. Since RS/hyper is interactive, the operator may select the desired level of understanding on a particular topic. These topics are linked, through a hypertext interface, so that the information is presented coherently and efficiently. Compared to written texts and references, RS/hyper has been shown in preliminary tests to reduce XRDRS training and problem solving time by a factor of 16. RS/hyper will train novice users of XRDRS equipment so that the data acquired from such machines will be reliable in an industrial environment. Since the software educates the user, the results of the data will be more accurately represented before interpretation. The experienced user should find RS/hyper useful as a reference of XRDRS and related information.

Abstract:
Parmi les matériaux piézo-électriques, les pérovskites ferroélectriques à base de plomb sont connus pour avoir les meilleurs coefficients piézo-électriques et couplage électromécanique. Ils sont largement utilisés dans diverses applications industrielles et technologiques. Les "ferroélectrique relaxeurs" appartiennent à cette famille. Leur structure est caractérisée par la présence de nanorégions polaires orientées de façon aléatoire. Dans cette thèse, nous nous sommes intéressés à l'étude des propriétés structurales et dynamiques de matériaux ferroélectriques et relaxeurs tels que PbTiO3, PbZr0.52Ti0.48O3, PbMg1/3Nb2/3O3 (PMN), PbZn1/3Nb2/3O3, et PbMg1/3Ta2/3O3 (PMT). La structure à longue et courte portée a été étudiée par diffraction de neutrons et spectroscopie d'absorption des rayons X (XAFS), alors que la spectroscopie hyper-Raman (HR) est utilisée pour sonder les vibrations. L'analyse de la structure locale de matériaux pérovskites complexes AB'B''O3 montre que la pression diminue le désordre statique des gros cations occupant le site B, tandis que le champ électrique appliqué a un effet opposé. Cette distortion induite sous champ pourrait être à l'origine des forts coefficient piézoélectrique dans ces matériaux. La diffusion HR dans PMN et PMT a permis d'observer pour la première fois le "mode mou" responsable de la dépendance en température de la constante diélectrique. L'analyse des règles de sélection et la description en modes propres des vibrations actives en HR, permet de rendre compte de l'implication de chaque atome dans le comportement structural en température des ferroélectriques relaxeurs
Among piezoelectric materials, lead-based ferroelectric perovskites are known to have the largest piezoelectric coefficients and electromechanical coupling. They are widely used in dfferent industrial and technological applications. The so-called "relaxors" belong to this family. Their structure is characterized by the presence of randomly oriented polar nanoregions. In this thesis, we are interested in studying the structural and dynamical properties of prototypical ferroelectric materials and relaxors such as PbTiO3, PbZr0.52Ti0.48O3, PbMg1/3Nb2/3O3 (PMN), PbZn1/3Nb2/3O3, and PbMg1/3Ta2/3O3 (PMT). The long and short range structure has been investigated by neutron diffraction and X-ray absorption fine structure (XAFS), while hyper-Raman scattering (HRS) is used to probe the vibrations. The local structure analysis of complex perovskite materials AB'B''O3 shows that pressure reduces the static disorder of the large cation occupying the B-site, while an applied electric field has an opposite effect. This field-induced distortion might relate to the large piezoelectric coefficient in such materials. HRS in PMN and PMT allows the first observation of the "primary" soft mode responsible for the temperature dependence of the dielectric constant. The selection rule analysis reveals the nature of the HRS active vibrational bands and enables us to get insights about the involvement of each atom in the structural modifications upon temperature

Abstract:
La proteína X del virus de la hepatitis B (HBx), codificada por el gen X de este virus (HBX), es crucial para la replicación del VHB y regula la expresión de múltiples genes del huésped. Por este motivo deben existir zonas altamente conservadas a nivel nucleotídico (HBX) y/o aminoacídico (HBx), esenciales para su actividad reguladora. Sin embargo, las inserciones y deleciones descritas en el extremo C-terminal de esta proteína, parecen limitar la posibilidad de que estas zonas estén en la región 3’ de HBX, por eso se ha escogido estudiar mediante la tecnología de secuenciación masiva la variabilidad del extremo 5’de HBX. En esta región se han identificado 2 regiones híper-conservadas, que además podrían ser utilizadas como potenciales dianas terapéuticas para una nueva estrategia de tratamiento antiviral basada en la terapia génica contra la HBx mediante el silenciamiento génico. Este tratamiento podría ser útil para conseguir la “cura funcional” de la infección en todos los estadios clínicos y en presencia de todos los genotipos virales. Además de la conservación del extremo 5’ de HBX en esta tesis también se ha estudiado en profundidad la complejidad y variantes específicas de la quasiespecies (QS) de esta región en pacientes en diferentes etapas clínicas de la infección crónica por el VHB HBeAg (-), para investigar su relación con los mecanismos que permiten controlar la replicación viral. El estudio de la complejidad y la variabilidad de la QS de un grupo de pacientes con infección crónica HBeAg (-) (IC) evidenció, en estos pacientes, una QS más conservada y compleja que en los pacientes con hepatitis crónica (en presencia o no de lesiones hepáticas como la cirrosis y el HCC), caracterizada por la presencia de un alto número de haplotipos altamente mutados probablemente a muy bajas frecuencias, por lo que no afectan a la conservación. Asimismo, se ha evidenciado un grupo de mutaciones genotipo-específicas. En concreto se ha descrito un patrón mutacional en los haplotipos de genotipo D de los IC asociado a una probable reducción de la expresión viral. Este patrón mutacional genotipo-específico evidencia la necesidad de genotipar adecuadamente el virus en el seguimiento de los pacientes infectados por VHB. En resumen, el extremo 5’de HBX contiene regiones híper-conservadas que podrían ser esenciales para la función de la HBx y explotadas como diana para el tratamiento antiviral basado en terapia génica. Además la QS de los pacientes IC presenta características diferenciales de complejidad y conservación. Estas características junto con patrones de mutaciones genotipo-específicas, podrían estar relacionados con la baja replicación del VHB en estos pacientes.
The hepatitis B virus X protein (HBx), encoded by the X gene of this virus (HBX), is crucial for HBV replication and regulates the expression of multiple host genes. For this reason, there must be highly conserved areas at nucleotide (HBX) and/or amino acid (HBx) level, essential for its regulatory activity. However, the insertions and deletions described in the C-terminal end of this protein seem to limit the possibility that these areas are located in the 3’ region of HBX. By this reason, the 5’-end of HBX has been chosen to study its conservation by next-generation sequencing. In this region, 2 hyper-conserved regions have been identified. These regions could be used as potential therapeutic targets for a new antiviral treatment strategy, based on gene therapy against HBx through gene silencing. This treatment could be useful to achieve “functional cure” of the HBV infection in all clinical stages and in the presence of all viral genotypes. In addition to the conservation of the 5’ end of HBX, in this thesis the complexity and specific variants of the quasispecies (QS) of this region have also been studied in depth in patients at different clinical stages of HBeAg (-) chronic HBV infection, to investigate its relationship with the mechanisms that allow to control viral replication. The study of the complexity and variability of the QS of a group of patients with HBeAg (-) chronic infection (IC) showed a more conserved and complex QS in these patients than in patients with chronic hepatitis (with or without liver lesion such liver cirrhosis and HCC), characterized by the presence of a high number of highly mutated haplotypes, probably at very low frequencies, so they do not affect conservation. Likewise, a group of genotype-specific mutations has been evidenced. In particular, a mutational pattern has been described in genotype D haplotypes of IC patients, probably associated with a reduction of viral expression. This genotype-specific mutational pattern demonstrates the need to adequately genotype the virus in the HBV infected patients follow-up. In summary, the 5’-end of HBX contains hyper-conserved regions that could be essential for the HBx function and could be exploited as a target for antiviral treatment based on gene therapy. In addition, the IC patients’ QS presents differential characteristics of complexity and conservation. These characteristics, together with patterns of genotype-specific mutations, could be related to the low replication of HBV in these patients.

Abstract:
Dans cette thèse on développe une théorie générale des objets tressés et on l'applique à une étude de structures algébriques et topologiques. La partie I contient une théorie homologique des espaces vectoriels tressés et modules tressés, basée sur le coproduit de battage quantique. La construction d'un tressage structurel qui caractérise diverses structures - auto-distributives (AD), associatives, de Leibniz - permet de généraliser et unifier des homologies familières. Les hyper-bords de Loday, ainsi que certaines opérations homologiques, apparaissent naturellement dans cette interprétation. On présente ensuite des concepts de système tressé et module multi-tressé. Appliquée aux bigèbres, bimodules, produits croisés et (bi)modules de Hopf et de Yetter-Drinfel'd, cette théorie donne leurs interprétations tressées, homologies et actions adjointes. La no- tion de produits tensoriels multi-tressés d'algèbres donne un cadre unificateur pour les doubles de Heisenberg et Drinfel'd, ainsi que les algèbres X de Cibils-Rosso et Y et Z de Panaite. La partie III est orientée vers la topologie. On propose une catégorification des groupes de tresses virtuelles en termes d'objets tressés dans une catégorie symétrique (CS). Cette approche de double tressage donne une source de représentations de V Bn et un traitement catégorique des racks virtuels de Manturov et de la représentation de Burau tordue. On définit ensuite des structures AD dans une CS arbitraire et on les munit d'un tressage. Les techniques tressées de la partie I amènent alors à une théorie homologique des structures AD catégoriques. Les algèbres associatives, de Leibniz et de Hopf rentrent dans ce cadre catégorique.

Hydrogen bonding between the counter ions for a number of room temperature ionic liquids has attracted numerous research interests. In the present work, we perform a theoretical investigation of H-bonding in ion pairs containing BF4- or PF6-. The cations under this study are ammonium ions, pyridium ion and some imidazolium ions (Im+). Through the B-F•••H distances, it is found that the NR3H+ cations form strongest H-bonding with BF4-, followed by PyH+ and then the Im+ cationss. Analysis of the values of orbital interaction energies also leads to the same conclusion. The same studies conducted on the ion-pairs containing PF6-, again, indicates the same trend of capability forming H-bonding, major field of these NR3H+ > PyH+>Im+. Within the ammonium ion series, the tendency for H-bond formation obtained is NH4+ > NR3H+ > NR2H2+□NRH3+. The calculated shielding constants of fluorine and phosphorous manifest that both 19F and 31P (I=1/2 for either nucleus) NMR are promising spectroscopic tool for probe of H-bonding since these isotopes not only possess high gyromagnetic ratio but also natural abundance (100%). The electric field gradient of the boron atom changes with hydrogen-bond formation, indicating a non-zero quadrupole coupling constant, □, for boron. Therefore, measurements the values of □ for 11B through nuclear quadrupole resonance spectroscopy provide another available technique for similar studies. Analysis of the magnitudes of E(2) in the fluoromethanes reveal that the degree of negative hyperconjugation (NHC) increases with increasing number of fluorine substitution. This observation is consistent with the trend reported in literature acquired theoretically or experimentally. Employing values of calculated E(2), we have found that NHC can account for the B-F bond strength in the BFnH4-n series. Futhermore, the concept of NHC can be applied for rationalizing the lower negative charge of the F-atoms than expected as compared to those on F-atoms in PF6- anion. We also propose that the NHC effect in BF4- plays an important role for reducing its ability in forming H-bonding with cations under this study.

The purpose of the present doctoral dissertation is the calculation of the electric multipole moments (dipole up to hexadecapole) of acetylenic chains under the general formulas H-(C≡C)n-H, Χ-(C≡C)n-H and Χ-(C≡C)n-X, n=1–7, X=F, Cl, Br, I, CN, NC, the systematic study of the (hyper)polarizabilities of the non substituted acetylenic chains Η-(C≡C)n-H, n=3–7 and finally the calculation of interaction induced electric properties of systems of the general formula Η-(C≡C)n-H…Ηe, n=1– 7. In all cases considered the ab initio SCF and MP2 methods have been used along with the very popular DFT methods B3LYP, B3PW91 and mPW1PW91. For the electric multipole moment calculations the cc-pVDZ basis set has been used in all cases and special attention has been paid in the way the properties of interest change by changing the substituent at the ends of the acetylenic chains. For the electric (hyper)polarizability calculations on the non substituted acetylenic chains H-(C≡C)n- H minimally polarized basis sets have been used and comparison was made with the results obtained by using larger basis sets. In order to calculate the above mentioned properties the finite field method was applied. Finally, calculations were performed in order to calculate the interaction induced electric properties of the systems Η-(C≡C)n- H…Ηe for two particular configurations while in order to avoid the basis set superposition error the Boys-Bernardi counterpoise method has been applied.

Abstract:

Phase transition materials (PTM) have garnered immense interest in concurrent post-CMOS electronics, due to their unique properties such as - electrically driven abrupt resistance switching, hysteresis, and high selectivity. The phase transitions can be attributed to diverse material-specific phenomena, including- correlated electrons, filamentary ion diffusion, and dimerization. In this research, we explore the application space for these materials through extensive device-circuit co-design and propose new ideas harnessing their unique electrical properties. The abrupt transitions and high selectivity of PTMs enable steep (< 60 mV/decade) switching characteristics in Hyper-FET, a promising post-CMOS transistor. We explore device-circuit co-design methodology for Hyper-FET and identify the criterion for material down-selection. We evaluate the achievable voltage swing, energy-delay trade-off, and noise response for this novel device. In addition to the application in low power logic device, PTMs can actively facilitate non-volatile memory design. We propose a PTM augmented Spin Transfer Torque (STT) MRAM that utilizes selective phase transitions to boost the sense margin and stability of stored data, simultaneously. We show that such selective transitions can also be used to improve other MRAM designs with separate read/write paths, avoiding the possibility of read-write conflicts. Further, we analyze the application of PTMs as selectors in cross-point memories. We establish a general simulation framework for cross-point memory array with PTM based selector. We explore the biasing constraints, develop detailed design methodology, and deduce figures of merit for PTM selectors. We also develop a computationally efficient compact model to estimate the leakage through the sneak paths in a cross-point array. Subsequently, we present a new sense amplifier design utilizing PTM, which offers built-in tunable reference with low power and area demand. Finally, we show that the hysteretic characteristics of unipolar PTMs can be utilized to achieve highly efficient rectification. We validate the idea by demonstrating significant design improvements in a Cockcroft-Walton Multiplier, implemented with TS based rectifiers. We emphasize the need to explore other PTMs with high endurance, thermal stability, and faster switching to enable many more innovative applications in the future.
