Though widely accepted, it is not proven that supermassive compact objects (SMCOs) residing in galactic centers are black holes. In particular, the Milky Way’s SMCO can be a giant nontopological soliton, Q-ball, made of a scalar field: this fits perfectly all observational data. Similar but tiny Q-balls produced in the early Universe may constitute, partly or fully, the dark matter. This picture explains in a natural way, why our SMCO has very low accretion rate and why the observed angular size of the corresponding radio source is much smaller than expected. Interactions between dark-matter Q-balls may explain how SMCOs were seeded in galaxies and resolve well-known problems of standard (non-interacting) dark matter.

The simultaneous operation for the Q- switched Nd: YAG laser at 1.06 and the tunable color-center laser over 1.12～1.26 μm has been realized by using a LiF: F2- color-center crystal both as the Q-switcher for the Nd:YAG laser and as the active medium for the color-center laser. The interaction of the two lasers has been analyzed and calculated with the rate equations. The pulse duration of YAG laser is compressed, in agreement with the experimental results.

In photosynthetic reaction centers, a quinone molecule, Q{sub B}, is the terminal acceptor in light-induced electron transfer. The crystal structure of the reaction center implicates the protonatable amiho acid residues L212Glu and L213Asp in the binding of Q{sub B} to the reaction center and in proton transfer to the anionic forms of Q{sub B} generated by electron transfer from Q{sub A}. Here we report the construction of the double mutant L212Ala-L213Ala by site-specific mutagenesis, and the isolation and preliminary biophysical characterization of revertant and suppressor strains that have regained the ability to grow under photosynthetic conditions. Our results show that neither L212Glu nor L213Asp is essential for efficient light-induced electron or proton transfer in Rhodobacter capsulatus and that second-site mutations, located within the QB binding pocket or at a more distant site, can compensate for mutations at L212 and L213. Acquisition of a single negatively charged residue (at position L213, or on the other side of the binding pocket at position L225) or loss of a positively charged residue (at position M231) is sufficient to restore activity to the complex.

The characteristic oxidation or reduction reaction mechanisms of short-chain oxidoreductase (SCOR) enzymes involve a highly conserved Asp-Ser-Tyr-Lys catalytic tetrad. The SCOR enzyme Q9HYA2 from the pathogenic bacterium Pseudomonas aeruginosa was recognized to possess an atypical catalytic tetrad composed of Lys118-Ser146-Thr159-Arg163. Orthologs of Q9HYA2 containing the unusual catalytic tetrad along with conserved substrate and cofactor recognition residues were identified in 27 additional species, the majority of which are bacterial pathogens. However, this atypical catalytic tetrad was not represented within the Protein Data Bank. The crystal structures of unligated and NADPH-complexed Q9HYA2 were determined at 2.3 A resolution. Structural alignment to a polyketide ketoreductase (KR), a typical SCOR, demonstrated that Q9HYA2's Lys118, Ser146, and Arg163 superimposed upon the KR's catalytic Asp114, Ser144, and Lys161, respectively. However, only the backbone of Q9HYA2's Thr159 overlapped KR's catalytic Tyr157. The Thr159 hydroxyl in apo Q9HYA2 is poorly positioned for participating in catalysis. In the Q9HYA2-NADPH complex, the Thr159 side chain was modeled in two alternate rotamers, one of which is positioned to interact with other members of the tetrad and the bound cofactor. A chloride ion is bound at the position normally occupied by the catalytic tyrosine hydroxyl. The putative active site of Q9HYA2 contains a chemical moiety at each catalytically important position of a typical SCOR enzyme. This is the first observation of a SCOR protein with this alternate catalytic center that includes threonine replacing the catalytic tyrosine and an ion replacing the hydroxyl moiety of the catalytic tyrosine.

The glycerophosphodiesterase (GpdQ) from Enterobacter aerogenes is a promiscuous, dinuclear metallohydrolase that has potential application in the remediation of organophosphate nerve agents and pesticides. GpdQ employs an unusual reaction mechanism in which the enzyme is predominantly mononuclear in the resting state, and substrate binding induces the formation of the catalytically competent dinuclear center (Hadler et al. J. Am. Chem. Soc. 2008, 130, 14129). Reactivity is further modulated by the coordination flexibility of Asn80, a ligand that binds to the second, loosely bound metal ion (Hadler et al. J. Am. Chem. Soc. 2009, 131, 11900). It is proposed that hydrolysis is initiated by a terminal, metal-bound hydroxide molecule which is activated at unusually low pH by electrostatic/hydrogen bonding interactions with a bridging hydroxide species. In this study, electronic structure analysis of the dinuclear center is employed to study the coordination environment of the dinuclear center at the resting and product-bound stage of catalysis. This is achieved through the use of variable temperature, variable field magnetic circular dichroism experiments involving the Co(II)-substituted wild type enzyme and its Asn80Asp variant. The data support the above model for the catalytic mechanism whereby the metal ion-bridging hydroxide molecule activates a terminally bound hydroxide nucleophile. Replacement of Asn80 by an aspartate residue does prevent coordination flexibility but also leads to cleavage of the mu-hydroxide bridge and reduced reactivity. This is the first study to investigate the electronic structure of an enzyme with a mu-1,1-carboxylate bridged dicobalt(II) center.

Time-resolved cw EPR measurements of the Rhodobacter (Rb) sphaeroides R-26 reaction center primary donor triplet state excited with plane-polarised light are reported. The pigment composition of the reaction center was chemically modified, so that the bacteriopheophytin molecule in the cofactor branch which is inactive towards electron transfer was replaced by plant pheophytin a. This enabled selective excitation of the bacteriopheophytin and pheophytin molecules, and provided conditions for a high-quality magnetophotoselection study. For the first time, orientation of the Q{sub y} optical transition dipole moment relative to the molecular frame of the bacteriopheophytin in the active cofactor branch is determined. Of the four orientations allowed by magnetophotoselection, one was chosen as the most plausible. The corresponding Q{sub y} vector is tilted from the bacteriopheophytin tetrapyrrole plane by 15 deg. , and projects onto this plane almost on the y-molecular axis. It is suggested that the deviation of the vector from the molecular plane results from an interaction of bacteriopheophytin with the neighbouring molecule of accessory bacteriochlorophyll.

Full Text Available Abstract Background Normalization is critical for accurate gene expression analysis. A significant challenge in the quantitation of gene expression from biofluids samples is the inability to quantify RNA concentration prior to analysis, underscoring the need for robust normalization tools for this sample type. In this investigation, we evaluated various methods of normalization to determine the optimal approach for quantifying microRNA (miRNA expression from biofluids and tissue samples when using the TaqMan® Megaplex™ high-throughput RT-qPCR platform with low RNA inputs. Findings We compared seven normalization methods in the analysis of variation of miRNA expression from biofluid and tissue samples. We developed a novel variant of the common mean-centering normalization strategy, herein referred to as mean-centering restricted (MCR normalization, which is adapted to the TaqMan Megaplex RT-qPCR platform, but is likely applicable to other high-throughput RT-qPCR-based platforms. Our results indicate that MCR normalization performs comparable to or better than both standard mean-centering and other normalization methods. We also propose an extension of this method to be used when migrating biomarker signatures from Megaplex to singleplex RT-qPCR platforms, based on the identification of a small number of normalizer miRNAs that closely track the mean of expressed miRNAs. Conclusions We developed the MCR method for normalizing miRNA expression from biofluids samples when using the TaqMan Megaplex RT-qPCR platform. Our results suggest that normalization based on the mean of all fully observed (fully detected miRNAs minimizes technical variance in normalized expression values, and that a small number of normalizer miRNAs can be selected when migrating from Megaplex to singleplex assays. In our study, we find that normalization methods that focus on a restricted set of miRNAs tend to perform better than methods that focus on all miRNAs, including

We propose a potentially practical scheme for efficient generation of entanglement with two nitrogen-vacancy centers (NVC) coupled to a whispering-gallery mode cavity. By virtue of the virtual-photon-excitation, the entanglement with two separate NVC can be produced in a deterministic way. The required operations are very close to the capabilities of current experimental techniques. The effects of decoherence induced by the cavity decay and the atomic spontaneous decay are also investigated.

The triplet states of photosystem II core particles from spinach were studied using time-resolved cw EPR technique at different reduction states of the iron--quinone complex of the reaction center primary electron acceptor. With doubly reduced primary acceptor, the well-known photosystem II triplet state characterised by zero-field splitting parameters |D|=0.0286 cm(-1), |E|=0.0044 cm(-1) was detected. When the primary acceptor was singly reduced either chemically or photochemically, a triplet state of a different spectral shape was observed, bearing the same D and E values and characteristic spin polarization pattern arising from RC radical pair recombination. The latter triplet state was strongly temperature dependent disappearing at T=100 K, and had a much faster decay than the former one. Based on its properties, this triplet state was also ascribed to the photosystem II reaction center. A sequence of electron-transfer events in the reaction centers is proposed that explains the dependence of the triplet state properties on the reduction state of the iron--quinone primary acceptor complex.

Human chromosome 14q32.2 harbors the germline-derived primary DLK1-MEG3 intergenic differentially methylated region (IG-DMR) and the postfertilization-derived secondary MEG3-DMR, together with multiple imprinted genes. Although previous studies in cases with microdeletions and epimutations affecting both DMRs and paternal/maternal uniparental disomy 14-like phenotypes argue for a critical regulatory function of the two DMRs for the 14q32.2 imprinted region, the precise role of the individual DMR remains to be clarified. We studied an infant with upd(14)pat body and placental phenotypes and a heterozygous microdeletion involving the IG-DMR alone (patient 1) and a neonate with upd(14)pat body, but no placental phenotype and a heterozygous microdeletion involving the MEG3-DMR alone (patient 2). The results generated from the analysis of these two patients imply that the IG-DMR and the MEG3-DMR function as imprinting control centers in the placenta and the body, respectively, with a hierarchical interaction for the methylation pattern in the body governed by the IG-DMR. To our knowledge, this is the first study demonstrating an essential long-range imprinting regulatory function for the secondary DMR.

The crystallographic observation of two symmetry-related branches of electron transfer cofactors in the structure of the bacterial reaction center (RC) 13 years ago [1] remains an enigma in light of experimental observations that show that only the A branch is active in the initial electron transfer steps in wild-type RCs. Unidirectional electron flow has been attributed to localized asymmetries between the A and B branches that lead to differences in: (1) the electronic couplings of the cofactors [2]; (2) the relative electrostatic environments of the cofactors, caused by amino acid differences which modulate the free energies of their charge-separated states [3] and/or create a higher dielectric constant on the active side, resulting in a stronger static field for stabilizing A-branch charge transfer states [4,5]. Some photo-induced bleaching of H{sub B} has been observed, in wild-type RCs following trapping of HA{sub A}{sup {minus}}[6], and in ''hybrid'' RCs where the redox potentials of cofactors were manipulated by pigment exchange [7] or mutagenesis [8]. Transient bleaching of the 530-nm band of H{sub B} was more easily observed in the hybrid RCs because the H{sub A} transition at 545 nm was shifted to {approximately}600 nm due to incorporation of a bacteriochlorophyll, designated ''{beta}'', at the H{sub A} site. No experiments to detect further electron transfer to Q{sub B} were done with either type of modified RCs. Many site-specific mutagenesis experiments have given us insight into the nature and magnitude of the effects that amino acid side chains can exert in tuning the relative energy levels of the cofactors to optimize the balance between forward and reverse reactions, and the large distances through which some of these effects are manifested. In this paper, we show that in mutant RCs of Rhodobacter capsulatus, P{sup +}Q{sub B}{sup {minus}} can be formed in the absence of prior formation of P{sup +}Q{sub A

Using a test based on parent-of-origin specific DNA methylation at the D15S63 (PW71) locus, we studied 358 patients (aged 1-33 years) for diagnostic confirmation of PWS and 60 infants (aged 0-12 months) with severe hypotonia of unknown origin. 57/358 patients were examined personally. 28/57 patients showed typical clinical signs of PWS and lacked the paternal PW71 band. 29-57 patients did not fulfill the diagnostic criteria for PWS and had a normal methylation pattern. This suggests that the test detects most if not all patients with typical PWS. 301/358 samples were sent to us from outside. The test confirmed the diagnosis in 105/301 patients. Most of the other 196 patients lacked neonatal hypotonia and hypogonadism. On the other hand, 27/60 hypotonic infants tested positive for PWS. These results indicate that PWS is often not recognized in infants and wrongly diagnosed in obese children and adults. We propose to perform the PW71 methylation test in every newborn with severe hypotonia of unknown origin to avoid unnecessary diagnostic procedures. In the course of diagnostic testing we and others have identified PWS and Angelman syndrome (AS) patients with apparently normal chromosomes of biparental inheritance, but abnormal DNA methylation and gene expression. The identification of microdeletions in some of these patients suggests the existence of an imprinting center within 30 kb proximal of SNRPN, which regulates the chromatin structure, DNA methylation and gene expression. We propose that the paternal copy of 15q11-13 has a euchromatoid structure, from which the PWS genes are transcribed, and that the maternal copy has a heterochromatoid structure from which the AS gene is transcribed. Depending on the parental origin of the mutation, both chromosomes of a patient have a heterochromatoid domain, which silences the PWS genes, or a euchromatoid domain, which silences the AS gene.

Limited data is available regarding the novel Reveal LinQ (LinQ) which is a new generation implantable loop recorders (ILRs). We performed a prospective, observational study of all consecutive patients undergoing conventional (Reveal XT; XT) and LinQ devices at our institution between January 2012 and December 2014. A total of 217 patients underwent ILR implantation. XT was implanted in 105 and LinQ in 112 patients. There were no significant differences in baseline characteristics between the two groups. LinQ implantation using the manufacturer's technique termed, "manufacturer's method" group had significantly higher incidence of pocket infection compared to XT (6/50, 12% vs 3/105, 3%, p=0.032). With modifications to the LinQ implantation technique (using a conventional scalpel and placing a suture when needed to the incision) termed "modified method" group, the rate of infection has decreased significantly compared to "manufacturer's method group" (0/62, 0% vs 6/50, 12%, p=0.004) (Table 3). In multivariate regression analysis, the only independent predictors of infection were younger age (OR 0.95; p=0.04), insertion of LinQ device (OR 30.02; p=0.006) and procedure time (OR 1.07; p=0.03). In our single-center, prospective, observational study we found that with the current implantable techniques, the novel insertable LinQ device is associated with increased risk of complications.

The diamond nitrogen-vacancy (NV) center is an excellent candidate for quantum information processing, whereas entangling separate NV centers is still of great experimental challenge. We propose an one-step conditional phase flip with three NV centers coupled to a whispering-gallery mode cavity by virtue of the Raman transition and smart qubit encoding. As decoherence is much suppressed, our scheme could work for more qubits. The experimental feasibility is justified.

The quasi-geostrophic Q vector is an important diagnostic tool for studying development of surface rainfall associated with large-scale weather systems and is calculated using data at single vertical level. When ageostrophic Q vector was introduced, it required data at two vertical levels. In this study, moist ageostrophic Q vector is modified so that it can be calculated using data at a single vertical level. The comparison study between the original and modified moist ageostrophic Q vectors is conducted using the data from 5 to 6 July 1991 during the torrential rainfall event associated with the Changjiang-Huaihe mei-yu front in China. The results reveal that divergences of original and modified moist ageostrophic Q vectors have similar horizontal distributions and their centers are almost located in the precipitation centers. This indicates that modified moist ageostrophic Q vector can be used to diagnose convective development with reasonable accuracy.

Full Text Available Abstract Background Oncogene amplification and overexpression occur in tumor cells. Amplification status may provide diagnostic and prognostic information and may lead to new treatment strategies. Chromosomal regions 8p12, 8q24, 11q13, 17q12 and 20q13 are recurrently amplified in breast cancers. Methods To assess the frequencies and clinical impact of amplifications, we analyzed 547 invasive breast tumors organized in a tissue microarray (TMA by fluorescence in situ hybridization (FISH and calculated correlations with histoclinical features and prognosis. BAC probes were designed for: (i two 8p12 subregions centered on RAB11FIP1 and FGFR1 loci, respectively; (ii 11q13 region centered on CCND1; (iii 12p13 region spanning NOL1; and (iv three 20q13 subregions centered on MYBL2, ZNF217 and AURKA, respectively. Regions 8q24 and 17q12 were analyzed with MYC and ERBB2 commercial probes, respectively. Results We observed amplification of 8p12 (amplified at RAB11FIP1 and/or FGFR1 in 22.8%, 8q24 in 6.1%, 11q13 in 19.6%, 12p13 in 4.1%, 17q12 in 9.9%, 20q13Z (amplified at ZNF217 only in 9.9%, and 20q13Co (co-amplification of two or three 20q13 loci in 8.5% of cases. The 8q24, 12p13, and 17q12 amplifications were correlated with high grade. The most frequent single amplifications were 8p12 (9.8%, 8q24 (3.3% and 12p13 (3.3%, 20q13Z and 20q13Co (1.6% regions. The 17q12 and 11q13 regions were never found amplified alone. The most frequent co-amplification was 8p12/11q13. Amplifications of 8p12 and 17q12 were associated with poor outcome. Amplification of 12p13 was associated with basal molecular subtype. Conclusion Our results establish the frequencies, prognostic impacts and subtype associations of various amplifications and co-amplifications in breast cancers.
Combining $Q_T$ and small-$x$ resummations
Marzani, Simone
2015-01-01
We analyze transverse momentum ($Q_T$) resummation of a colorless final state, e.g. Higgs production in gluon fusion or the production of a lepton pair via the Drell-Yan mechanism, in the limit where the invariant mass of the final state is much less then the center-of-mass energy, i.e. $Q^2\\ll s$. We show how the traditional resummation of logarithms of $Q_T/Q$ can be supplemented with the resummation of the leading logarithmic contributions at small $x=Q^2/s$ and we compute the necessary ingredients to perform such joint resummation.

The finite q-oscillator is a model that obeys the dynamics of the harmonic oscillator, with the operators of position, momentum and Hamiltonian being functions of elements of the q-algebra su{sub q}(2). The spectrum of position in this discrete system, in a fixed representation j, consists of 2j + 1 'sensor'-points x{sub s} = 1/2 [2s]{sub q}, s element of {l_brace}-j, -j+1, ..., j{r_brace}, and similarly for the momentum observable. The spectrum of energies is finite and equally spaced, so the system supports coherent states. The wavefunctions involve dual q-Kravchuk polynomials, which are solutions to a finite-difference Schroedinger equation. Time evolution (times a phase) defines the fractional Fourier-q-Kravchuk transform. In the classical limit as q {yields} 1 we recover the finite oscillator Lie algebra, the N = 2j {yields} {infinity} limit returns the Macfarlane-Biedenharn q-oscillator and both limits contract the generators to the standard quantum-mechanical harmonic oscillator.

In some stochastic environments the well-known reinforcement learning algorithm Q-learning performs very poorly. This poor performance is caused by large overestimations of action values, which result from a positive bias that is introduced because Q-learning uses the maximum action value as an appr

Confining vacua and Q-state Potts models with Q<1
Gliozzi, F
2007-01-01
In most Yang-Mills models the vacuum where magnetic monopoles condense coincides with that where center vortices percolate, thus it is not clear which of these two properties is most directly involved in producing confinement. It is pointed out that there is a class of 3D gauge models, which can be though of as duals of Q-state Potts models with Q < 1, where the magnetic monopole condensation is a necessary but not sufficient condition for percolation of center vortices. A set of numerical tests at Q=1/10 shows that there is a vacuum in which the magnetic monopole condensate does not yield confinement, in the sense that large Wilson loops obey a perimeter law. In such a vacuum the center vortices form a dilute gas of loops. At stronger coupling there is also a truly confining vacuum where both confining mechanisms are present.

The finite q-oscillator is a model that obeys the dynamics of the harmonic oscillator, with the operators of position, momentum and Hamiltonian being functions of elements of the q-algebra suq(2).

In this work we deal with non-topological solutions of the Q-ball type in two space-time dimensions, in models described by a single complex scalar field that engenders global symmetry. The main novelty is the presence of stable Q-balls solutions that live in a compact interval of the real line and appear from a family of models controlled by two distinct parameters. We find analytical solutions and study their charge and energy, and show how to control the parameters to make the Q-balls classically and quantum mechanically stable.

Full Text Available Q fever is a worldwide zoonosis with many acute and chronic manifestations caused by the pathogen Coxiella burnetii. Farm animals and pets are the main reservoirs of infection, and transmission to human beings is mainly accomplished through inhalation of contaminated aerosols. Persons at greatest risk are those in contact with farm animals and include farmers, abattoir workers, and veterinarians. The organs most commonly affected during Q fever are the heart, the arteries, the bones and the liver. The most common clinical presentation is an influenza-like illness with varying degrees of pneumonia and hepatitis. Although acute disease is usually self-limiting, people do occasionally die from this condition. Endocarditis is the most serious and most frequent clinical presentation of chronic Q fever. Vascular infection is the second most frequent presentation of Q fever. The diagnosis of Q fever is based on a significant increase in serum antibody titers. The treatment is effective and well tolerated, but must be adapted to the acute or chronic pattern with the tetracyclines to be considered the mainstay of antibiotic therapy. For the treatment of Q fever during pregnancy the use of long-term cotrimoxazole therapy is proposed.
q-ultraspherical polynomials for q a root of unity
Spiridonov, V P
1996-01-01
Properties of the q-ultraspherical polynomials for q being a primitive root of unity are derived using a formalism of the so_q(3) algebra. The orthogonality condition for these polynomials provides a new class of trigonometric identities representing discrete finite-dimensional analogs of q-beta integrals of Ramanujan.

Q-MOHRA takes into account the link (energy, hop count, link quality indicator etc.) and path (jitter) metrics for optimal path selection. The performance...... of Q-MOHRA is evaluated through intensive simulation and equated with Simple Hybrid Routing Protocol (SHRP) and Dynamic Multi-objective Routing Algorithm (DyMORA). The metrics such as Average Energy Consumption, Residual Energy, Packet Delivery Ratio, Jitter, and Normalized Routing Load are used...... for comparison. The performance of Q-MOHRA has been observed to outclass SHRP and DyMORA. It improves the Packet Delivery Ratio (PDR) by 13.72% as compared to SHRP and 28 % as compared to DyMORA.

We construct explicit examples of new axially symmetric, non-spinning Q-ball solutions that have not been studied so far. These solutions can be interpreted as angular excitations of the fundamental Q-balls and are related to the spherical harmonics. Correspondingly, they have higher energy and their energy densities possess two local maxima on the positive z-axis. We also study two Q-balls interacting via a potential term in 3+1 dimensions and construct examples of stationary, solitonic-like objects in (3+1)-dimensional flat space-time that consist of two interacting global scalar fields. We concentrate on configurations composed of one spinning and one non-spinning Q-ball and study the parameter-dependence of the energy and charges of the configuration. In addition, we present numerical evidence that for fixed values of the coupling constants two different types of 2-Q-ball solutions exist: solutions with defined parity, but also solutions which are asymmetric with respect to reflexion through the x-y-axis.

Under a variety of stress conditions, Photosystem II produces reactive oxygen species on both the reducing and oxidizing sides of the photosystem. A number of different sites including the Mn4O5Ca cluster, P680, PheoD1, QA, QB and cytochrome b559 have been hypothesized to produce reactive oxygen species in the photosystem. In this communication using Fourier-transform ion cyclotron resonance mass spectrometry we have identified several residues on the D1 and D2 proteins from spinach which are oxidatively modified and in close proximity to QA (D1 residues (239)F, (241)Q, (242)E and the D2 residues (238)P, (239)T, (242)E and (247)M) and PheoD1 (D1 residues (130)E, (133)L and (135)F). These residues may be associated with reactive oxygen species exit pathways located on the reducing side of the photosystem, and their modification may indicate that both QA and PheoD1 are sources of reactive oxygen species on the reducing side of Photosystem II.

International workshop on II Polarized Partons at High Q2 region 11 was held at the Yukawa Institute for Theoretical Physics, Kyoto University, Kyoto, Japan on October 13-14, 2000, as a satellite of the international conference ''SPIN 2000'' (Osaka, Japan, October 16-21,2000). This workshop was supported by RIKEN (The Institute of Physical and Chemical Research) and by Yukawa Institute. The scientific program was focused on the upcoming polarized collider RHIC. The workshop was also an annual meeting of RHIC Spin Collaboration (RSC). The number of participants was 55, including 28 foreign visitors and 8 foreign-resident Japanese participants, reflecting the international nature of the RHIC spin program. At the workshop there were 25 oral presentations in four sessions, (1) RHIC Spin Commissioning, (2) Polarized Partons, Present and Future, (3) New Ideas on Polarization Phenomena, (4) Strategy for the Coming Spin Running. In (1) the successful polarized proton commissioning and the readiness of the accelerator for the physics program impressed us. In (2) and (3) active discussions were made on the new structure function to be firstly measured at RHIC, and several new theoretical ideas were presented. In session (4) we have established a plan for the beam time requirement toward the first collision of polarized protons. These proceedings include the transparencies presented at the workshop. The discussion on ''Strategy for the Coming Spin Running'' was summarized by the chairman of the session, S. Vigdor and G. Bunce.

The structure functions g1p and g1n have been measured over the range 0.014 < x < 0.9 and 1 < Q2 < 40 GeV2 using deep-inelastic scattering of 48 GeV longitudinally polarized electrons from polarized protons and deuterons. We find that the Q2 dependence of g1p (g1n) at fixed x is very similar to that of the spin-averaged structure function F1p (F1n). From a NLO QCD fit to all available data we find Gamma{sub 1}{sup p} Gamma{sub 1}{sup n}=0.176 {+-} 0.003 {+-} 0.007$ at Q2=5 GeV2, in agreement with the Bjorken sum rule prediction of 0.182 {+-} 0.005.

We investigate the presence of non-topological solutions of the Q-ball type in (1 , 1) spacetime dimensions. The model engenders the global U (1) symmetry and is of the k-field type, since it contains a new term, of the fourth-order power in the derivative of the complex scalar field. It supports analytical solution of the Q-ball type which is stable quantum mechanically. The new solution engenders an interesting behavior, with the charge and energy densities unveiling a splitting profile.

Autologous breast reconstruction with the deep inferior epigastric perforator (DIEP) or muscle-sparing transverse rectus abdominis myocutaneous (ms-TRAM) flap is a common method in the majority of patients after mastectomy. Because of an increased perioperative risk profile the benefit in older patients is questionable. To assess the postoperative quality of life and peri- and post-operative complications of older compared to younger patients is the aim of this retrospective study. In a retrospective analysis 39 older (i.e. >60 years) and 140 younger patients (i.e. breast reconstruction in the Department of Plastic Surgery at the University Hospital of Erlangen-Nuernberg were surveyed at least 6 month postoperative using the BREAST-Q questionnaire. Correlations were generated between comorbidities and complications. Significant differences were observed regarding hospitalization, pre-existing diseases and the choice of DIEP versus ms-TRAM flaps. Parameters such as major and minor complications, bulging or hernia and risk factors (e.g. smoking or obesity) showed no significant differences. The results of the questionnaire parameters showed no significant difference between both groups, revealing high satisfaction with the aesthetic result and an improvement in quality of life independent of age. Autologous breast reconstruction after mastectomy generates a gain in quality of life and shows a good to excellent overall satisfaction in older as well as younger patients. Despite a longer hospitalization and a different risk profile there were no significant differences regarding minor and major complications in the postoperative course. Hence autologous breast reconstruction for older patients is justified and should be taken into consideration.

Full Text Available A substantial proportion of familial colorectal cancer (CRC is not a consequence of known susceptibility loci, such as mismatch repair (MMR genes, supporting the existence of additional loci. To identify novel CRC loci, we conducted a genome-wide linkage scan in 356 white families with no evidence of defective MMR (i.e., no loss of tumor expression of MMR proteins, no microsatellite instability (MSI-high tumors, or no evidence of linkage to MMR genes. Families were ascertained via the Colon Cancer Family Registry multi-site NCI-supported consortium (Colon CFR, the City of Hope Comprehensive Cancer Center, and Memorial University of Newfoundland. A total of 1,612 individuals (average 5.0 per family including 2.2 affected were genotyped using genome-wide single nucleotide polymorphism linkage arrays; parametric and non-parametric linkage analysis used MERLIN in a priori-defined family groups. Five lod scores greater than 3.0 were observed assuming heterogeneity. The greatest were among families with mean age of diagnosis less than 50 years at 4q21.1 (dominant HLOD = 4.51, α = 0.84, 145.40 cM, rs10518142 and among all families at 12q24.32 (dominant HLOD = 3.60, α = 0.48, 285.15 cM, rs952093. Among families with four or more affected individuals and among clinic-based families, a common peak was observed at 15q22.31 (101.40 cM, rs1477798; dominant HLOD = 3.07, α = 0.29; dominant HLOD = 3.03, α = 0.32, respectively. Analysis of families with only two affected individuals yielded a peak at 8q13.2 (recessive HLOD = 3.02, α = 0.51, 132.52 cM, rs1319036. These previously unreported linkage peaks demonstrate the continued utility of family-based data in complex traits and suggest that new CRC risk alleles remain to be elucidated.
De novo dup(7)(q21q22.2) and cytogenetics of 7q21q34 duplications.
Rivera, H
2013-01-01
We report on a constitutional dup(7)(q21q22.2) and compile 25 similar mid-7q imbalances in order to sort out relevant cytogenetic aspects. The propositus was first karyotyped elsewhere at 2 years of age and found to have a de novo 7q+ chromosome. When reassessed at 22 years of age, he exhibited overt mental disability, marked speech delay, mild short stature, frontal bossing, and mild dysmorphisms. The patient's chromosomes were analyzed in metaphases from a lymphocyte culture by means of G-banding and FISH assays with a wcp 7 and two dual probes, namely ELN (7q11)/D7S2686 (7q22) and ELN (7q11)/D7S486, D7S522 (q31). G-bands revealed a 7q21q22.2 direct duplication that was confirmed by FISH: the 7q+ was entirely painted with the wcp and had two 7q22 signals but a single 7q31 signal. Thus, the patient's karyotype was 46,XY, dup(7)(q21q22.2).ish dup(7)(q21 q22.2)(wcp7+, ELN+, D7S2686++, D7S486+)dn. Among 26 interstitial duplications confined to the segment 7q21q34, 13 were contiguous de novo duplications, one was due to a de novo ins (19;7), and 12 were inherited from carriers of inter-/intrachromosomal insertions or complex rearrangements. Mean paternal and maternal ages in de novo contiguous duplications of paternal/unknown (n = 9) or maternal/unknown (n = 10) descent were 33.44 and 30.9 yr whereas median ages were 29 and 30, respectively. The patient's clinical picture confirms the mild or moderate phenotypical repercussion of mid-7q duplications; among 25 patients born alive, 24 (including six teenagers or older) were still alive when reported on.

The aim of this study was to investigate the association between drug exposure and disease severity in SCA types 1, 2, 3 and 6. The Clinical Research Consortium for Spinocerebellar Ataxias (CRC-SCA) enrolled 319 participants with SCA1, 2, 3, and 6 from 12 medical centers in the United States and repeatedly measured clinical severity by the Scale for Assessment and Rating of Ataxia (SARA), the Unified Huntington's Disease Rating Scale part IV (UHDRS-IV), and the 9-item Patient Health Questionnaire during July 2009 to May 2012. We employed generalized estimating equations in regression models to study the longitudinal effects of coenzyme Q10 (CoQ10), statin, and vitamin E on clinical severity of ataxia after adjusting for age, sex, and pathological CAG repeat number. Cross-sectionally, exposure to CoQ10 was associated with lower SARA and higher UHDRS-IV scores in SCA1 and 3. No association was found between statins, vitamin E, and clinical outcome. Longitudinally, CoQ10, statins, and vitamin E did not change the rates of clinical deterioration indexed by SARA and UHDRS-IV scores within 2 years. CoQ10 is associated with better clinical outcome in SCA1 and 3. These drug exposures did not appear to influence clinical progression within 2 years. Further studies are warranted to confirm the association.

The $q$-binomial coefficients $\\qbinom{n}{m}=\\prod_{i=1}^m(1-q^{n-m+i})/(1-q^i)$, for integers $0\\le m\\le n$, are known to be polynomials with non-negative integer coefficients. This readily follows from the $q$-binomial theorem, or the many combinatorial interpretations of $\\qbinom{n}{m}$. In this note we conjecture an arithmetically motivated generalisation of the non-negativity property for products of ratios of $q$-factorials that happen to be polynomials.

Full Text Available The term spirituality is notoriously difficult to define, as is evidenced by the discussions between contemporary sociologists of religion. If there are any central elements to such a definition, they revolve around the search for the sacred, and the view that certain practices or beliefs lead to humans being placed in a position of privileged access to the transcendent dimension. Often such spiritual experiences and insights are the result of practices that seek deeper communication with the divine, or stem from contemplative reflection upon one’s purpose in a broader context of universal ontology. This discussion seeks to probe Q for its understanding of spirituality, both in terms of the way the text promotes communication with the divine, as well as offering heightened spiritual experience for adherents to its teaching. In essence, this is an exploration of the way the new religious movement reflected in Q offered its followers contact with the transcendent within the context of everyday human life.
Production and Decay of (Q Q Qbar Qbar) States
Karliner, Marek; Nussinov, Shmuel
2016-01-01
The question of whether there exist bound states of two heavy quarks $Q=(c,b)$ and antiquarks $\\bar Q = (\\bar c, \\bar b)$, distinct from a pair of quark-antiquark mesons, has been debated for more than forty years. We suggest some means of producing and observing $Q_1 Q_2 \\bar Q_3 \\bar Q_4$ resonant states, concentrating on the $c c \\bar c \\bar c$ channel which is most easily produced and the $b b \\bar b \\bar b$ channel which has a better chance of being relatively narrow. We obtain $M_{(cc)(\\bar c \\bar c)} = 6,192 \\pm 25$ MeV and $M_{(bb)(\\bar b \\bar b)} = 18,826 \\pm 25$ MeV, for the charmed and bottom tetraquarks, respectively. Experimental search for these states in the relevant mass region is highly desirable.
Effective Q-Q Interactions in Constituent Quark Models
Glozman, L Ya; Plessas, W; Varga, K; Wagenbrun, R F
1998-01-01
We study the performance of some recent potential models suggested as effective interactions between constituent quarks. In particular, we address constituent quark models for baryons with hybrid Q-Q interactions stemming from one-gluon plus meson exchanges. Upon recalculating two of such models we find them to fail in describing the N and \\Delta spectra. Our calculations are based on accurate solutions of the three-quark systems in both a variational Schrödinger and a rigorous Faddeev approach. It is argued that hybrid {Q-Q} interactions encounter difficulties in describing baryon spectra due to the specific contributions from one-gluon and pion exchanges together. In contrast, a chiral constituent quark model with a Q-Q interaction solely derived from Goldstone-boson exchange is capable of providing a unified description of both the N and \\Delta spectra in good agreement with phenomenology.

Prader-Willi syndrome is caused by the lack of paternal contribution for the imprinted 15q11-q13 region that originates through a number of mechanisms such as paternal deletion of 15q11-q13, maternal uniparental disomy, or by an imprinting defect due to epimutations in the paternal imprinting center. In the present report, we describe a female patient with complex maternal uniparental trisomy for the 15q11-q13 Prader-Willi syndrome critical region due to a de novo interstitial duplication of 15q11-q13 region that is present in one of the maternal homologs. As a result, the patient has three maternally derived copies of the Prader-Willi syndrome critical region and absence of paternal 15 contribution and thus, presents with a Prader-Willi syndrome phenotype with risk for developing additional phenotypes (e.g., autism and psychiatric phenotypes) characteristic of maternally derived duplications of this region. We suggest that this is a rather unique mechanism leading to Prader-Willi syndrome that has not been previously reported.

Classical nontopological soliton configurations are considered within the theory of a complex scalar field with a gauged U(1) symmetry. Their existence and stability against dispersion are demonstrated and some of their properties are investigated analytically and numerically. The soliton configuration is such that inside the soliton the local U(1) symmetry is broken, the gauge field becomes massive, and for a range of values of the coupling constants the soliton becomes a superconductor pushing the charge to the surface. Furthermore, because of the repulsive Coulomb force, there is a maximum size for these objects, making impossible the existence of Q matter in bulk form. We also briefly discuss solitons with fermions in a U(1) gauge theory.

Phenotypic, karyotypic, and developmental homology between affected children of carriers of an inverted insertion (9) (q22.1q34.3q34.1) led to recognition of a new chromosome syndrome: dup 9q34. Individuals with dup 9q34 have slight psychomotor retardation, understand simple directions, and acquire a limited vocabulary. In childhood, many are hyperactive. Clinical features include low birth weight, normal birth length, and initial poor feeding and thriving. Musculo-skeletal systems are affected: there are joint contractures, long thin limbs, and striking arachnodactyly. There is abnormal implantation of the thumb, increased space between the first and second fingers, and excess digital creases. Marfan syndrome was a provisional diagnosis for several cases prior to cytogenetic analysis. Cardiovascular and ocular systems are minimally affected, erythema and heart murmurs occur, and ptosis and strabismus are frequent, but lens dislocation is not observed. Features at birth include: dolichocephaly, facial asymmetry, narrow horizontal palpebral fissures, microphthalmia, prominent nasal bridge, small mouth, thin upper lip with down-turned corners, and slight retrognathia. In older children, retrognathia is diminished and the nose becomes long and narrow. The new culture and chromosome banding techniques enable sorting of cases with the distal dup 9q phenotype into two groups. The cases with a longer dup 9q are more likely to develop with life-threatening congenital anomalies. The cases with the shorter dup 9q34 have a less severe long-term prognosis and will benefit, together with their parents, from special education. Female carriers of the inv ins(9) (q22.1q34.3q34.1) have about a 31% risk in each pregnancy to conceive a fetus affected by the dup 9q34 syndrome. A comparable figure is not yet available for male carriers.
New ${\\cal W}_{q,p}(sl(2))$ algebras from the elliptic algebra ${\\cal A}_{q,p}({\\hat sl}(2)_c)$

We construct operators t(z) in the elliptic algebra introduced by Foda et al. ${\\cal A}_{q,p}({\\hat sl}(2)_c)$. They close an exchange algebra when p^m=q^{c+2} for m integer. In addition they commute when p=q^{2k} for k integer non-zero, and they belong to the center of ${\\cal A}_{q,p}({\\hat sl}(2)_c)$ when k is odd. The Poisson structures obtained for t(z) in these classical limits are identical to the q-deformed Virasoro Poisson algebra, characterizing the exchange algebras at generic values of p, q and m as new ${\\cal W}_{q,p}(sl(2))$ algebras.

The Stanford Linear Accelerator Center (SLAC) uses a flash lamp pumped Ti:Sapphire laser to generate the electron beam inside of the Linac. This laser system was installed at the SLAC Polarized Light Source in 1993. During the past, the system has been upgraded in several steps (eg. installation of Rhodium coated reflectors, cavity redesign, and remote controlled wavelength tunability). Q-switching the laser cavity to increase the peak pulse energy was successfully investigated and further improves the capabilities of the laser system for future polarized beam experiments. Two Pockels cells were used to perform the Q-switch and various diagnostics were used to characterize the modified laser pulse. The timing in relation to the laser trigger, pulse width, and pulse shape applied to the Q-switching Pockels cells (PC) were optimized. No damage to the laser cavity or optical elements occurred. At optimal conditions of Q-switching, the pulse energy of the laser increased from 0.4 mJ to over 3 mJ in a 300 ns pulse. The Q-switched pulse energy can be further increased by extending the hold-off pulse applied to the PC. The laser pulse produced by the Q-switch was long enough (full width half maximum (FWHM) > 200 ns) for pulse shaping and demonstrated good intensity stability (< 0.5% jitter). The increase in output power suggests that Q-switching will be used for future accelerator projects.

Full Text Available Aphidicolin (APC-induced chromosomal breakage was analyzed for women representing three generations of a single family and carrying a Robertsonian translocation rob(14q21q. Fluorescence in situ hybridization (FISH analysis confirmed the dicentric constitution of the derived chromosome and indicated the absence of beta-satellite signal at the translocation region. Per-individual analysis of metaphases from APC-treated peripheral blood lymphocyte cultures identified significantly nonrandom chromosomal breakage at the translocation region in all three individuals examined. The APC-inducible fragility at the 14q21q translocation region suggests that this rearrangement was the result of chromosomal mutation at fragile site(s in the progenitor chromosomes, or that this fragility was the result of the fusion of nonfragile progenitor chromosomes.
Two-Centered Magical Charge Orbits
Andrianopoli, Laura; Ferrara, Sergio; Marrani, Alessio; Trigiante, Mario
2011-01-01
We determine the two-centered generic charge orbits of magical N = 2 and maximal N = 8 supergravity theories in four dimensions. These orbits are classified by seven U-duality invariant polynomials, which group together into four invariants under the horizontal symmetry group SL(2,R). These latter are expected to disentangle different physical properties of the two-centered black-hole system. The invariant with the lowest degree in charges is the symplectic product (Q1,Q2), known to control the mutual non-locality of the two centers.

Coxiella burnetii, the causative agent of Q fever, is present worldwide. Recent studies have shown that this bacterium is an emerging pathogen in French Guiana and has a high prevalence (24% of community-acquired pneumonia). In this review, we focus on the peculiar epidemiology of Q fever in French Guiana. We place it in the context of the epidemiology of the disease in the surrounding countries of South America. We also review the clinical features of Q fever in this region, which has severe initial presentation but low mortality rates. These characteristics seem to be linked to a unique genotype (genotype 17). Finally, we discuss the issue of the animal reservoir of C. burnetii in French Guiana, which is still unknown. Further studies are necessary to identify this reservoir. Identification of this reservoir will improve the understanding of the Q fever epidemic in French Guiana and will provide new tools to control this public health problem.

We describe the polarization topology of the vector beams emerging from a patterned birefringent liquid crystal plate with a topological charge $q$ at its center ($q$-plate). The polarization topological structures for different $q$-plates and different input polarization states have been studied experimentally by measuring the Stokes parameters point-by-point in the beam transverse plane. Furthermore, we used a tuned $q=1/2$-plate to generate cylindrical vector beams with radial or azimuthal polarizations, with the possibility of switching dynamically between these two cases by simply changing the linear polarization of the input beam.

Pure partial trisomy 4q syndrome in a child with der(9)ins(9;4)(q34.3;q26q35.2)mat: Partial trisomy 4q is a rare chromosomal abnormality and mostly results from unbalanced inheritance of balanced parental chromosomal translocations. Here, we present a 5-year-old boy with partial trisomy 4q who exhibited distinctive features of 'pure' partial trisomy 4q syndrome including moderate mental and growth retardation, microcephaly, peculiar face appearance, tooth anomaly, cleft palate, language handicap, preaxial polydactyly, and urogenital anomaly. Karyotype analysis of the child revealed der(9)ins(9;4)(q34.3;q26q35.2) inherited from mother carrying ins(9;4)(q34.3;q26q35.2) resulting in trisomy of the 4q26qter segment. Whole chromosome painting, locus specific, and subtelomeric FISH analysis in mother proved that q26qter of the chromosome 4 segment was directly inserted into the telomeric sequence in chromosome 9, and depending on nature of the rearrangement in mother, karyotype of the child was determined to be pure partial 4q trisomy. This is the first report of this kind of rearrangement causing pure partial trisomy 4q with accompanying white matter change demonstrated by MRI and bilateral preaxial polydactyly of both hands.

Strong subsurface attenuation leads to distortion of amplitudes and phases of seismic waves propagating inside the earth. The amplitude and the dispersion losses from attenuation are often compensated for during prestack depth migration. However, most attenuation compensation or Qcompensation migration algorithms require an estimate of the background Q model. We have developed a wave-equation gradient optimization method that inverts for the subsurface Q distribution by minimizing a skeletonized misfit function ∈, where ∈ is the sum of the squared differences between the observed and the predicted peak/centroid-frequency shifts of the early arrivals. The gradient is computed by migrating the observed traces weighted by the frequency shift residuals. The background Q model is perturbed until the predicted and the observed traces have the same peak frequencies or the same centroid frequencies. Numerical tests determined that an improved accuracy of the Q model by wave-equation Q tomography leads to a noticeable improvement in migration image quality. © 2016 Society of Exploration Geophysicists.
Multivariable q-Racah polynomials
Van Diejen, J F
1996-01-01
The Koornwinder-Macdonald multivariable generalization of the Askey-Wilson polynomials is studied for parameters satisfying a truncation condition such that the orthogonality measure becomes discrete with support on a finite grid. For this parameter regime the polynomials may be seen as a multivariable counterpart of the (one-variable) q-Racah polynomials. We present the discrete orthogonality measure, expressions for the normalization constants converting the polynomials into an orthonormal system (in terms of the normalization constant for the unit polynomial), and we discuss the limit q\\rightarrow 1 leading to multivariable Racah type polynomials. Of special interest is the situation that q lies on the unit circle; in that case it is found that there exists a natural parameter domain for which the discrete orthogonality measure (which is complex in general) becomes real-valued and positive. We investigate the properties of a finite-dimensional discrete integral transform for functions over the grid, whose ...
Q-enhanced racetrack microresonators
Chamorro-Posada, P.
2017-03-01
A Q-enhancement strategy for racetrack microresonators is put forward. The design is based on the modification of the resonator geometry in order to mitigate the two main sources of radiation loss in the presence of curved waveguides: the discontinuities at the junctions between straight waveguides and the bent sections, and the continuous loss at the curved waveguide sectors. At the same time, the modifications of the geometry do not affect the versatility of coupling of racetrack resonators in integrated optical circuits, which is their main advantage over ring microresonators. The proposal is applied to the design of high-Q racetrack resonators for the silicon nitride CMOS-compatible platform having bent radii amenable for large-scale photonic integration. Numerical calculations show over 100% improvement of the Q factor in Si3N4/SiO2 resonators.

In a second step we solve the Schr\\"odinger equation, to determine, whether the resulting potentials are sufficiently attractive to host a bound state, which would indicate the existence of a stable $q q \\bar b \\bar b$ tetraquark. We find a bound state for $qq=(ud-du)/\\sqrt{2}$ with corresponding quantum numbers $I(J^ P)=0(1^+)$ and evidence against the existence of bound states with isospin $I=1$ or $qq \\in \\{cc,ss \\}$

Full Text Available The multiple zeta values (MZVs possess a rich algebraic structure of algebraic relations, which is conjecturally determined by two different (shuffle and stuffle products of a certain algebra of noncommutative words. In a recent work, Bachmann constructed a q-analogue of the MZVs—the so-called bi-brackets—for which the two products are dual to each other, in a very natural way. We overview Bachmann’s construction and discuss the radial asymptotics of the bi-brackets, its links to the MZVs, and related linear (independence questions of the q-analogue.
Moments of q-Normal and conditional q-Normal distributions
2015-01-01
We calculate moments and moment generating functions of two distributions: the so called $q-$Normal and the so called conditional $q-$Normal distributions. These distributions generalize both Normal ($q=1),$ Wigner ($% q=0,$ $q-$Normal) and Kesten-McKay ($q=0,$ conditional $q-$Normal) distributions. As a by product we get asymptotic properties of some expansions in modified Bessel functions.

The group delay of a low Q antenna is shown to be around 1.3 ns, whereas...... a high Q antenna has group delay of around 22 ns. It is due to this huge group delay variation characteristics of high Q antennas, that signal distortion might occur in the radio system with high Q antennas....

The objective of this study was to characterize hearing loss in individuals with deletions of distal chromsome18q and to identify the smallest region of overlap of their deletions, thereby identifying potential causative genes. The clinical data were collected via a retrospective case study. Molecular data were obtained via high-resolution chromosome microarray analysis. The study was conducted as a component of the ongoing research protocols at the Chromosome 18 Clinical Research Center at the University of Texas Health Science Center at San Antonio. Thirty-eight participants with a deletion of the distal portion of the long arm of chromosome 18 were recruited to this study. The participants underwent an otologic examination as well as a basic audiometry evaluation. Blood samples were obtained, and high-resolution chromosome microarray analysis was performed. Pure tone averages and speech discrimination scores were determined for each participant. The region of hemizygosity for each participant was determined to within 2 Kb each of their breakpoints. Twenty-four participants (63%) had high-frequency hearing loss, similar to the pattern seen in presbycusis. Comparison of microarray results allowed identification of eight genes, including the candidate gene for dysmyelination (MBP). Individuals with a deletion of a 2.8 Mb region of 18q23 have a high probability (83%) of high-frequency sensorineural hearing loss.

The t(8;21)(q22;q22) translocation is specifically observed in acute myeloid leukemia (AML) M2 subtype, whereas del(5q) is one of the most common cytogenetic aberrations in myelodysplastic syndromes (MDS). Thus, t(8;21)(q22;q22) and del(5q) appear to be mutually exclusive, and the association between them has not been characterized yet. Here, we report an 81-year-old woman with coexistent t(8;21)(q22;q22) and del(5q) at initial diagnosis. The bone marrow was infiltrated with 18.4% myeloblasts, and showed marked myeloid and erythroid dysplasia. Myeloblasts were positive for CD19 and CD56 as well as CD13, CD33, CD34 and HLA-DR. G-banding and spectral karyotyping showed 46,XX,del(5)(q?),t(8;21)(q22;q22)[18]/46,XX[2]. Both del(5)(q?) and t(8;21)(q22;q22) were present in a single clone. Fluorescence in situ hybridization (FISH) on metaphase spreads detected a RUNX1/RUNX1T1 fusion signal on the der(8)t(8;21)(q22;q22), and confirmed deletion of CSF1R signaling at 5q33-q34 on the del(5)(q?). Furthermore, FISH on interphase nuclei revealed that the RUNX1/RUNX1T1 fusion signal and deletion of CSF1R signaling were found in 66.0% and 58.0% of interphase cells, respectively, suggesting that del(5)(q?) occurred in cells with RUNX1/RUNX1T1. These results indicated a diagnosis of AML with t(8;21)(q22;q22)/RUNX1/RUNX1T1 rather than MDS, even though the percentage of bone marrow myeloblasts was less than 20%. Based on these findings, together with those of other reported cases, del(5q) seems to be an extremely rare but recurrent secondary aberration in AML with t(8;21)(q22;q22).

Purpose Rare, recurrent chromosome 1q21.1 duplications have been associated with developmental delay, congenital anomalies, and macrocephaly in children. Data on adult clinical expression would help to inform genetic counseling. Methods A systematic review of 22 studies reporting 107 individuals (59 children and 48 adults) with 1q21.1 duplications was conducted. We compiled the available phenotypic data to attempt to identify the most highly associated clinical features and to determine expression in adults. We also report on seven adult cases newly identified in the studies of schizophrenia and tetralogy of Fallot at our center. Results Five cases were ascertained as controls, 32 as relatives of probands, and 70 as having clinical features: autism spectrum disorder (n = 15), congenital heart disease (n = 12), schizophrenia (n = 10), or other, mostly developmental, features (n = 33). The 1q21.1 duplication was significantly enriched in the cohorts with schizophrenia (P = 0.0155) and tetralogy of Fallot (P = 0.0040) at our center as compared with controls. There was a paucity of clinical data for adults; the most common features, other than those used for ascertainment, included macrocephaly and abnormalities of possible connective tissue origin (e.g., carpal tunnel syndrome). Conclusion Further data are needed to characterize lifetime expression of 1q21.1 duplications. These initial results, however, suggest that anticipatory care should include attention to later-onset conditions such as schizophrenia. PMID:23018752
New multilevel codes over GF(q)
Wu, Jiantian; Costello, Daniel J., Jr.
1992-01-01
Set partitioning to multi-dimensional signal spaces over GF(q), particularly GF sup q-1(q) and GF sup q (q), and show how to construct both multi-level block codes and multi-level trellis codes over GF(q). Two classes of multi-level (n, k, d) block codes over GF(q) with block length n, number of information symbols k, and minimum distance d sub min greater than or = d, are presented. These two classes of codes use Reed-Solomon codes as component codes. They can be easily decoded as block length q-1 Reed-Solomon codes or block length q or q + 1 extended Reed-Solomon codes using multi-stage decoding. Many of these codes have larger distances than comparable q-ary block codes, as component codes. Low rate q-ary convolutional codes, work error correcting convolutional codes, and binary-to-q-ary convolutional codes can also be used to construct multi-level trellis codes over GF(q) or binary-to-q-ary trellis codes, some of which have better performance than the above block codes. All of the new codes have simple decoding algorithms based on hard decision multi-stage decoding.
Q methodology in health economics.
Baker, Rachel; Thompson, Carl; Mannion, Russell
2006-01-01
The recognition that health economists need to understand the meaning of data if they are to adequately understand research findings which challenge conventional economic theory has led to the growth of qualitative modes of enquiry in health economics. The use of qualitative methods of exploration and description alongside quantitative techniques gives rise to a number of epistemological, ontological and methodological challenges: difficulties in accounting for subjectivity in choices, the need for rigour and transparency in method, and problems of disciplinary acceptability to health economists. Q methodology is introduced as a means of overcoming some of these challenges. We argue that Q offers a means of exploring subjectivity, beliefs and values while retaining the transparency, rigour and mathematical underpinnings of quantitative techniques. The various stages of Q methodological enquiry are outlined alongside potential areas of application in health economics, before discussing the strengths and limitations of the approach. We conclude that Q methodology is a useful addition to economists' methodological armoury and one that merits further consideration and evaluation in the study of health services.
Molecular diagnosis of coenzyme Q10 deficiency.
Yubero, Delia; Montero, Raquel; Armstrong, Judith; Espinós, Carmen; Palau, Francesc; Santos-Ocaña, Carlos; Salviati, Leonardo; Navas, Placido; Artuch, Rafael
2015-01-01
Coenzyme Q10 (CoQ) deficiency syndromes comprise a growing number of neurological and extraneurological disorders. Primary-genetic but also secondary CoQ deficiencies have been reported. The biochemical determination of CoQ is a good tool for the rapid identification of CoQ deficiencies but does not allow the selection of candidate genes for molecular diagnosis. Moreover, the metabolic pathway for CoQ synthesis is an intricate and not well-understood process, where a large number of genes are implicated. Thus, only next-generation sequencing techniques (either genetic panels of whole-exome and -genome sequencing) are at present appropriate for a rapid and realistic molecular diagnosis of these syndromes. The potential treatability of CoQ deficiency strongly supports the necessity of a rapid molecular characterization of patients, since primary CoQ deficiencies may respond well to CoQ treatment.

q-deformed harmonic and Clifford analysis and the q-Hermite and Laguerre polynomials
Coulembier, Kevin
2010-01-01
We define a q-deformation of the Dirac operator, inspired by the one dimensional q-derivative. This implies a q-deformation of the partial derivatives. By taking the square of this Dirac operator we find a q-deformation of the Laplace operator. This allows to construct q-deformed Schroedinger equations in higher dimensions. The equivalence of these Schroedinger equations with those defined on q-Euclidean space in quantum variables is shown. We also define the m-dimensional q-Clifford-Hermite polynomials and show their connection with the q-Laguerre polynomials. These polynomials are orthogonal with respect to an m-dimensional q-integration, which is related to integration on q-Euclidean space. The q-Laguerre polynomials are the eigenvectors of an su_q(1|1)-representation.

Electrochemistry of Q-graphene.

A newly synthesised type of graphene, Q-Graphene, has been physically and electrochemically characterised with Scanning and Transmission Electron Microscopy (SEM, TEM), X-ray Photoelectron Spectroscopy (XPS) and Cyclic Voltammetry (CV). Interpretation of SEM, TEM and XPS data reveal the material to consist of hollow carbon nanospheres of multi-layer graphene (viz. graphite), which exhibit a total oxygen content of ca. 36.0% (atomic weight via XPS). In addition to the carbon structures present, spherical magnesium oxide particles of ≤50 nm in diameter are abundantly present in the sample (ca. 16.2%). Interestingly, although the TEM/SEM images show macroporous carbon structures, Raman spectroscopy shows peaks typically characteristic of graphene, which suggests the material is highly heterogeneous and consists of many types of carbon allotropes. Q-Graphene is electrochemically characterised using both inner-sphere and outer-sphere electrochemical redox probes, namely potassium ferrocyanide(II), hexaammine-ruthenium(III) chloride and hexachloroiridate(III), in addition to the biologically relevant and electroactive analytes, norepinephrine, β-nicotinamide adenine dinucleotide (NADH) and l-ascorbic acid. The electrochemical response of Q-Graphene is benchmarked against edge plane- and basal plane-pyrolytic graphite (EPPG and BPPG respectively), pristine graphene and graphite alternatives. Q-Graphene is found to exhibit fast electron transfer kinetics, likely due to its high proportion of folded edges and surface defects, exhibiting a response similar to that of EPPG - which exhibits fast electron transfer rates due to the high proportion of edge plane sites it possesses. Furthermore, we demonstrate that the specific oxygen content plays a pivotal role in dictating the observed electrochemical response, which is analyte dependant. Consequently there is potential for this new member of the graphene family to be beneficially utilised in various electrochemical

In the framework of the color-magnetic interaction, we systematically investigate the mass splittings of the QQ anti Q anti q tetraquark states and estimate their rough masses in this work. These systems include the explicitly exotic states cc anti b anti q and bb anti c anti q and the hidden exotic states cc anti c anti q, cb anti b anti q, bc anti c anti q, and bb anti b anti q. If a state around the estimated mass region can be observed, its nature as a genuine tetraquark is favored. The strong decay patterns shown here will be helpful to the experimental search for these exotic states. (orig.)

Neutron stars are extremely relativistic objects which abound in our universe and yet are poorly understood, due to the high uncertainty on how matter behaves in the extreme conditions which prevail in the stellar core. It has recently been pointed out that the moment of inertia I, the Love number lambda and the spin-induced quadrupole moment Q of an isolated neutron star, are related through functions which are practically independent of the equation of state. These surprising universal I-lambda-Q relations pave the way for a better understanding of neutron stars, most notably via gravitational-wave emission. Gravitational-wave observations will probe highly-dynamical binaries and it is important to understand whether the universality of the I-lambda-Q relations survive strong-field and finite-size effects. We apply a Post-Newtonian-Affine approach to model tidal deformations in compact binaries and show that the I-lambda relation depends on the inspiral frequency, but is insensitive to the equation of state...
Non-Collision Singularities in the Planar Two-Center-Two-Body Problem
Xue, Jinxin; Dolgopyat, Dmitry
2016-08-01
In this paper, we study a restricted four-body problem called the planar two-center-two-body problem. In the plane, we have two fixed centers Q 1 and Q 2 of masses 1, and two moving bodies Q 3 and Q 4 of masses {μ≪ 1}. They interact via Newtonian potential. Q 3 is captured by Q 2, and Q 4 travels back and forth between two centers. Based on a model of Gerver, we prove that there is a Cantor set of initial conditions that lead to solutions of the Hamiltonian system whose velocities are accelerated to infinity within finite time avoiding all earlier collisions. This problem is a simplified model for the planar four-body problem case of the Painlevé conjecture.

Duplications of the long arm of chromosome 1 are rare. Distal duplications are the most common and have been reported as either pure trisomy or unbalanced translocations. The paucity of cases with pure distal 1q duplications has made it difficult to delineate a partial distal trisomy 1q syndrome. Here, we report 2 patients with overlapping 1q duplications detected by G-banding. Array CGH and FISH were performed to characterize the duplicated segments, exclude the involvement of other chromosomes and determine the orientation of the duplication. Patient 1 presents with a mild phenotype and carries a 22.5-Mb 1q41q43 duplication. Patient 2 presents with a pure 1q42.13qter inverted duplication of 21.5 Mb, one of the smallest distal 1q duplications ever described and one of the few cases characterized by array CGH, thus contributing to a better characterization of distal 1q duplication syndrome.

A family of q-coherent states is constructed allowing us to obtain a new quantized version of the harmonic oscillator. These q-states are normalized and form an overcomplete set resolving the unity with respect to the appropriate Jackson measure if 0 < q < 1. We only consider here those values of q such that q{sup -1} is a Pisot number. In this case the q-deformed integers ([n]{sub q}) form Fibonacci-like sequences of integers. We study the main physical characteristics of the corresponding quantum oscillator: localization in the configuration and in the phase spaces, probability distributions and related statistical features and semi-classical phase space trajectories whose periodicity is related with the fact that q is an algebraic number.

In this paper the question 'is the q-Fourier transform of a q-Gaussian a q'-Gaussian (with some q') up to a constant factor?' is studied for the whole range of q in (- infty, 3). This question is connected with applicability of the q-Fourier transform in the study of limit processes in nonextensive statistical mechanics. Using the functional differential equation approach we prove that the answer is affirmative if and only if 1 <= q < 3, excluding two particular cases of q < 1, namely q=1/2 and q=2/3. Complementarily, we discuss some applications of the q-Fourier transform to nonlinear partial differential equations such as the porous medium equation.

For very heavy quarks $Q$, relations derived from heavy-quark symmetry predict the existence of novel narrow doubly heavy tetraquark states of the form $Q_iQ_j \\bar q_k \\bar q_l$ (subscripts label flavors), where $q$ designates a light quark. By evaluating finite-mass corrections, we predict that double-beauty states composed of $bb\\bar u \\bar d$, $bb\\bar u \\bar s$, and $bb\\bar d \\bar s$ will be stable against strong decays, whereas the double-charm states $cc \\bar q_k \\bar q_l$, mixed beauty+charm states $bc \\bar q_k \\bar q_l$, and heavier $bb \\bar q_k \\bar q_l$ states will dissociate into pairs of heavy-light mesons. Observation of a new double-beauty state through its weak decays would establish the existence of tetraquarks and illuminate the role of heavy color-antitriplet diquarks as hadron constituents.

We present some basic properties, such as the transformations between these two equations, the representations and the value distribution of meromorphic solutions of q-difference Riccati equations, and the q-Casorati determinant of meromorphic solutions of second-order linear q-difference equations. In particular, we find that the meromorphic solutions of these two equations are concerned with the q-Gamma function when q∈ℂ such that 0<|q|<1. Some examples are also listed to illustrate our results.

Three hundred and thirty-nine athletes had their Q angle measured. The mean of right-side Q angles was higher than left side, and the mean Q angle was higher in women than in men. The Q angle was positively associated with years of jogging, and negatively with years of soccer, swimming...... and sports participation at all. It is concluded that the use of Q angle measurements is questionable....
RECENT ADVANCES IN THE 5Q- SYNDROME

Full Text Available The 5q- syndrome is the most distinct of the myelodysplastic syndromes (MDS and patients with this disorder have a deletion of chromosome 5q [del(5q] as the sole karyotypic abnormality. Several genes mapping to the commonly deleted region of the 5q- syndrome have been implicated in disease pathogenesis in recent years. Haploinsufficiency of the ribosomal gene RPS14 has been shown to cause the erythroid defect in the 5q- syndrome. Loss of the microRNA genes miR-145 and miR-146a has been associated with the thrombocytosis observed in 5q- syndrome patients. Haploinsufficiency of CSNK1A1 leads to hematopoietic stem cell expansion in mice and may play a role in the initial clonal expansion in patients with 5q- syndrome. Moreover, a subset of patients harbor mutation of the remaining CSNK1A1 allele. Mouse models of the 5q- syndrome, which recapitulate the key features of the human disease, indicate that a p53-dependent mechanism underlies the pathophysiology of this disorder. Importantly, activation of p53 has been demonstrated in the human 5q- syndrome. Recurrent TP53 mutations have been associated with an increased risk of disease evolution and with decreased response to the drug lenalidomide in del(5q MDS patients. Potential new therapeutic agents for del(5q MDS include the translation enhancer L-leucine.

We consider proper Klein surfaces X of algebraic genus p≥2, having an automorphismφ of prime order n with quotient space X/〈φ〉 of algebraic genus q. These Klein surfaces axe calledq-n-gonal surfaces and they axe n-sheeted covers of surfaces of algebraic genus q. In this paper weextend the results of the already studied cases n ≤3 to this more general situation. Given p≥2, weobtain, for each prime n, the (admissible) values q for which there exists a q-n-gonal surface of algebraicgenus p. Furthermore, for each p and for each admissible q, it is possible to check all topological typesof q-n-gonal surfaces with algebraic genus p. Several examples are given: q-pentagonal surfaces andq-n-gonal bordered surfaces with topological genus g = 0,1.

In this paper we discuss symmetrically self-dual spaces, which are simply real vector spaces with a symmetric bilinear form. Certain subsets of the space will be called q-positive, where q is the quadratic form induced by the original bilinear form. The notion of q-positivity generalizes the classical notion of the monotonicity of a subset of a product of a Banach space and its dual. Maximal q-positivity then generalizes maximal monotonicity. We discuss concepts generalizing the representations of monotone sets by convex functions, as well as the number of maximally q-positive extensions of a q-positive set. We also discuss symmetrically self-dual Banach spaces, in which we add a Banach space structure, giving new characterizations of maximal q-positivity. The paper finishes with two new examples.

An 11-year-old boy was referred for chromosomal analysis because of precocious development and behavioral problems suggestive of the fragile X syndrome. The cytogenetic fragile X studies were normal, but a routine GTG-banded karyotype revealed an abnormal male karyotype with a Robertsonian translocation between the two chromosome 14`s: 46,XY,t(14q14q). Paternal karyotyping revealed another abnormal karyotype: 46,XY,t(13q14q). A brother had the same karyotype as the father; the mother was deceased. In order to determine if the apparently balanced t(14q14q) in the proband might be the cause of the clinical findings, molecular analysis of the origin of the chromosome 14`s was initiated. Southern blotting and hybridization with D4S13 showed that the proband had two copies of one maternal allele which was shared by his brother. The brother`s second allele corresponded to one of the paternal alleles; the proband had no alleles from the father. Analysis of four other VNTRs demonstrated the probability of paternity to be greater than 99%. Thus, the t(14q14q) was most likely composed of two maternal chromosome 14`s. Further characterization of the t(14q14q) by dinucleotide repeat polymorphic markers is in progress to determine whether it has arisen from maternal isodisomy or heterodisomy. Several cases of uniparental disomy for chromosome 14 have been reported recently. Paternal disomy appears to be associated with more severe congenital anomalies and mental retardation, whereas maternal disomy may be associated with premature puberty and minimal intellectual impairment. The origin of the t(14q14q) in the present case may be related to the paternal translocation, as the segregation of the t(13q14q) in meiosis could lead to sperm that are nullisomic for chromosome 14.
Sl$_{q}$(2) realizations for Kepler and oscillator potentials and q-canonical transformations

1994-01-01
The realizations of the Lie algebra corresponding to the dynamical symmetry group SO(2,1) of the Kepler and oscillator potentials are q-deformed. The q-canonical transformation connecting two realizations is given and a general definition for q-canonical transformation is deduced. q-Schr\\"{o}dinger equation for a Kepler like potential is obtained from the q-oscillator Schr\\"{o}dinger equation. Energy spectrum and the ground state wave function are calculated.
The importance of plasma membrane coenzyme Q in aging and stress responses.
Navas, Plácido; Villalba, José Manuel; de Cabo, Rafael
2007-06-01
The plasma membrane of eukaryotic cells is the limit to interact with the environment. This position implies receiving stress signals that affects its components such as phospholipids. Inserted inside these components is coenzyme Q that is a redox compound acting as antioxidant. Coenzyme Q is reduced by diverse dehydrogenase enzymes mainly NADH-cytochrome b(5) reductase and NAD(P)H:quinone reductase 1. Reduced coenzyme Q can prevent lipid peroxidation chain reaction by itself or by reducing other antioxidants such as alpha-tocopherol and ascorbate. The group formed by antioxidants and the enzymes able to reduce coenzyme Q constitutes a plasma membrane redox system that is regulated by conditions that induce oxidative stress. Growth factor removal, ethidium bromide-induced rho degrees cells, and vitamin E deficiency are some of the conditions where both coenzyme Q and its reductases are increased in the plasma membrane. This antioxidant system in the plasma membrane has been observed to participate in the healthy aging induced by calorie restriction. Furthermore, coenzyme Q regulates the release of ceramide from sphingomyelin, which is concentrated in the plasma membrane. This results from the non-competitive inhibition of the neutral sphingomyelinase by coenzyme Q particularly by its reduced form. Coenzyme Q in the plasma membrane is then the center of a complex antioxidant system preventing the accumulation of oxidative damage and regulating the externally initiated ceramide signaling pathway.
q-Exchangeability via quasi-invariance
Gnedin, Alexander
2009-01-01
For positive q, the q-exchangeability is introduced as quasi-invariance under permutations, with a special cocycle. This allows us to extend the q-analogue of de Finetti's theorem for binary sequences (arXiv:0905.0367) to the general real-valued sequences. In contrast to the classical case with q=1, the order on the reals plays for the q-analogues a significant role. An explicit construction of ergodic q-exchangeable measures involves a random shuffling of the set N={1,2,..} by iteration of the geometric choice. For q distinct from 1, the shuffling yields a probability measure Q that is supported by the group of bijections of N, and has the property of quasi-invariance under both left and right multiplications by finite permutations. We establish connections of the q-exchangeability to certain transient Markov chains on the q-Pascal pyramids and to invariant random flags over the Galois fields.

We study the masses of Qq(-Q)(-q)'states with JPC = 0++, 1++, 1+- and 2++ in the chiral SU(3) quark model,where Q is the heavy quark (c or b) and q (q') is the light quark (u, d or s). According to our numerical results, it is improbable to make the interpretation of [cn(-c)(-n)]1++ and [cn(-c)(-n)]2++ (n = u, d) states as X(3872) and Y(3940),respectively. However, it is interesting to find the tetraquarks in the bq(-b)(-q)'system.
The tree method for multidimensional q-Hahn and q-Racah polynomials
Scarabotti, Fabio
2009-01-01
We develop a tree method for multidimensional q-Hahn polynomials. We define them as eigenfunctions of a multidimensional q-difference operator and we use the factorization of this operator as a key tool. Then we define multidimensional q-Racah polynomials as the connection coefficients between different bases of q-Hahn polynomials. We show that our multidimensional q-Racah polynomials may be expressed as product of ordinary one-dimensional q-Racah polynomial by means of a suitable sequence of transplantations of edges of the trees.
Construction of normal numbers with respect to the $Q$-Cantor series expansion for certain $Q$

2009-01-01
A. Renyi \\cite{Renyi} made a definition that gives one generalization of simple normality in the context of $Q$-Cantor series. Similarly, in this paper we give a definition which generalizes the notion of normality in the context of $Q$-Cantor series. We will prove a theorem that allows us to concatenate sequences of digits that have a special property to give us the digits of a $Q$-normal number for certain $Q$. We will then use this theorem to construct a Q and a real number $x$ that is $Q$-normal.

η-quantum languages are discussed and some of their properties are derived. Furthermore the q-quantum language is defined. It is shown that L (A1 (×) A2 ) =L(A1)∩L(A2), L(A) = L(A1)∪L(A2). So over the same alphabet the intersection and union of two different q-quantum languages are also q-quantum languages.

Full Text Available Coenzyme Q10 (CoQ10, or ubiquinone is a small electron carrier of the mitochondrial respiratory chain with antioxidant properties. CoQ10 supplementation has been widely used for mitochondrial disorders. The rationale for using CoQ10 is very powerful when this compound is primary decreased because of defective synthesis. Primary CoQ10 deficiency is a treatable condition, so heightened “clinical awareness” about this diagnosis is essential. CoQ10 and its analogue, idebenone, have also been widely used in the treatment of other neurodegenerative disorders. These compounds could potentially play a therapeutic role in Parkinson’s disease, Huntington’s disease, amyotrophic lateral sclerosis, Friedreich’s ataxia, and other conditions which have been linked to mitochondrial dysfunction. This article reviews the physiological roles of CoQ10, as well as the rationale and the role in clinical practice of CoQ10 supplementation in different neurological diseases, from primary CoQ10 deficiency to neurodegenerative disorders.

Full Text Available Coenzyme Q10 (CoQ10 deficiency syndrome includes clinically heterogeneous mitochondrial diseases that show a variety of severe and debilitating symptoms. A multiprotein complex encoded by nuclear genes carries out CoQ10 biosynthesis. Mutations in any of these genes are responsible for the primary CoQ10 deficiency, but there are also different conditions that induce secondary CoQ10 deficiency including mitochondrial DNA (mtDNA depletion and mutations in genes involved in the fatty acid β-oxidation pathway. The diagnosis of CoQ10 deficiencies is determined by the decrease of its content in skeletal muscle and/or dermal skin fibroblasts. Dietary CoQ10 supplementation is the only available treatment for these deficiencies that require a rapid and distinct diagnosis. Here we review methods for determining CoQ10 content by HPLC separation and identification using alternative approaches including electrochemical detection and mass spectrometry. Also, we review procedures to determine the CoQ10 biosynthesis rate using labeled precursors.
q-Gamow States for intermediate energies

2016-01-01
In a recent paper [Nuc. Phys. A {\\bf 948}, (2016) 19] we have demonstrated the possible existence of Tsallis' q-Gamow states. Now, accelerators' experimental evidence for Tsallis' distributions has been ascertained only at very high energies. Here, instead, we develop a different set of q-Gamow states for which the associated q-Breit-Wigner distribution could easily be found at intermediate energies, for which accelerators are available at many locations. In this context, it should be strongly emphasized [Physica A {\\bf 388} (2009) 601] that, empirically, one never exactly and unambiguously "detects" pure Gaussians, but rather q-Gaussians. A prediction is made via Eq.(3.30)

Partial duplication of the long arm of chromosome 11 and the partial trisomy of 22q are uncommon karyotypic abnormalities. Here, we report the case of a 6-year-old girl who showed partial trisomy of 11q and 22q, as a result of a maternal balanced reciprocal translocation (11;22), and exhibited dysmorphic features, severe intellectual disability, brain malformations, and speech delay related to this unique chromosomal abnormality. Array comparative genomic hybridization (array CGH) revealed a gain in copy number on the long arm of chromosome 11, spanning at least 18.22 Mb. Additionally, there was a gain in copy number on the long arm of chromosome 22, spanning at least 3.46 Mb. FISH analysis using a chromosome 11 short arm telomere probe (11p14.2), a chromosome 11 long arm telomere probe (11q24.3), and a chromosome 22 long arm telomere probe (22q13.33) confirmed the origin of the marker chromosome. It has been confirmed by the State Key Laboratory of Medical Genetics of China that this is the first reported instance of the karyotype 47,XX, +der(22)t(11;22)(q23.3;q11.1)mat in the world. Our study reports an additional case that can be used to further characterize and delineate the clinical ramifications of partial trisomy of 11q and 22q.
Generating q-Commutator Identities and the q-BCH Formula

Full Text Available Motivated by the physical applications of q-calculus and of q-deformations, the aim of this paper is twofold. Firstly, we prove the q-deformed analogue of the celebrated theorem by Baker, Campbell, and Hausdorff for the product of two exponentials. We deal with the q-exponential function expq(x=∑n=0∞(xn/[n]q!, where [n]q=1+q+⋯+qn-1 denotes, as usual, the nth q-integer. We prove that if x and y are any noncommuting indeterminates, then expq(xexpq(y=expq(x+y+∑n=2∞Qn(x,y, where Qn(x,y is a sum of iterated q-commutators of x and y (on the right and on the left, possibly, where the q-commutator [y,x]q≔yx-qxy has always the innermost position. When [y,x]q=0, this expansion is consistent with the known result by Schützenberger-Cigler: expq(xexpq(y=expq(x+y. Our result improves and clarifies some existing results in the literature. Secondly, we provide an algorithmic procedure for obtaining identities between iterated q-commutators (of any length of x and y. These results can be used to obtain simplified presentation for the summands of the q-deformed Baker-Campbell-Hausdorff Formula.
Hi-Q Rotor - Low Wind Speed Technology
Energy Technology Data Exchange (ETDEWEB)

2010-01-11
The project objective was to optimize the performance of the Hi-Q Rotor. Early research funded by the California Energy Commission indicated the design might be advantageous over state-of-the-art turbines for collecting wind energy in low wind conditions. The Hi-Q Rotor is a new kind of rotor targeted for harvesting wind in Class 2, 3, and 4 sites, and has application in areas that are closer to cities, or 'load centers.' An advantage of the Hi-Q Rotor is that the rotor has non-conventional blade tips, producing less turbulence, and is quieter than standard wind turbine blades which is critical to the low-wind populated urban sites. Unlike state-of-the-art propeller type blades, the Hi-Q Rotor has six blades connected by end caps. In this phase of the research funded by DOE's Inventions and Innovation Program, the goal was to improve the current design by building a series of theoretical and numeric models, and composite prototypes to determine a best of class device. Development of the rotor was performed by aeronautical engineering and design firm, DARcorporation. From this investigation, an optimized design was determined and an 8-foot diameter, full-scale rotor was built and mounted using a Bergey LX-1 generator and furling system which were adapted to support the rotor. The Hi-Q Rotor was then tested side-by-side against the state-of-the-art Bergey XL-1 at the Alternative Energy Institute's Wind Test Center at West Texas State University for six weeks, and real time measurements of power generated were collected and compared. Early wind tunnel testing showed that the cut-in-speed of the Hi-Q rotor is much lower than a conventional tested HAWT enabling the Hi-Q Wind Turbine to begin collecting energy before a conventional HAWT has started spinning. Also, torque at low wind speeds for the Hi-Q Wind Turbine is higher than the tested conventional HAWT and enabled the wind turbine to generate power at lower wind speeds. Based on the data

Full Text Available Homologies between chromosome banding patterns and DNA sequences in the great apes and humans suggest an apparent common origin for these two lineages. The availability of DNA probes for specific regions of human chromosomes (5q31, 10q22, 13q32-33 and 19q13.1 led us to cross-hybridize these to chimpanzee (Pan troglodytes, PTR, gorilla (Gorilla gorilla, GGO and orangutan (Pongo pygmaeus, PPY chromosomes in a search for equivalent regions in the great apes. Positive hybridization signals to the chromosome 5q31-specific DNA probe were observed at HSA 5q31, PTR 4q31, GGO 4q31 and PPY 4q31, while fluorescent signals using the chromosome 10q22-specific DNA probe were noted at HSA 10q22, PTR 8q22, GGO 8q22 and PPY 7q22. The chromosome arms showing hybridization signals to the Quint-EssentialTM 13-specific DNA probe were identified as HSA 13q32-33, PTR 14q32-33, GGO 14q32-33 and PPY 14q32-33, while those presenting hybridization signals to the chromosome 19q13.1-specific DNA probe were identified as HSA 19q13.1, PTR 20q13, GGO 20q13 and PPY 20q13. All four probes presumably hybridized to homologous chromosomal locations in the apes, which suggests a homology of certain unique DNA sequences among hominoid species.

Coenzyme Q10 (CoQ10) is a lipid-soluble antioxidant synthesized in human body. This enzyme promotes immune system function and can be used as a dietary supplement. Rheumatoid arthritis (RA) is an autoimmune disease leading to chronic joint inflammation. RA results in severe destruction of cartilage and disability. This study aimed to investigate the effect of CoQ10 on inflammation and Th17 cell proliferation on an experimental rheumatoid arthritis (RA) mice model. CoQ10 or cotton seed oil as control was orally administrated once a day for seven weeks to mice with zymosan-induced arthritis (ZIA). Histological analysis of the joints was conducted using immunohistochemistry. Germinal center (GC) B cells, Th17 cells and Treg cells of the spleen tissue were examined by confocal microscopy staining. mRNA expression was measured by real-time PCR and protein levels were estimated by enzyme-linked immunosorbent assay (ELISA). Flow cytometric analysis (FACS) was used to evaluate Th17 cells and Treg cells. CoQ10 mitigated the severity of ZIA and decreased serum immunoglobulin concentrations. CoQ10 also reduced RANKL-induced osteoclastogenesis, inflammatory mediators and oxidant factors. Th17/Treg axis was reciprocally controlled by CoQ10 treatment. Moreover, CoQ10 treatment on normal mouse and human cells cultured in Th17 conditions decreased the number of Th17 cells and enhanced the number of Treg cells. CoQ10 alleviates arthritis in mice with ZIA declining inflammation, Th17 cells and osteoclast differentiation. These findings suggest that CoQ10 can be a potential therapeutic substance for RA.

In the framework of the color-magnetic interaction, we systematically investigate the mass splittings of the $QQ\\bar{Q}\\bar{q}$ tetraquark states and estimated their rough masses in this work. These systems include the explicitly exotic states $cc\\bar{b}\\bar{q}$ and $bb\\bar{c}\\bar{q}$ and the hidden exotic states $cc\\bar{c}\\bar{q}$, $cb\\bar{b}\\bar{q}$, $bc\\bar{c}\\bar{q}$, and $bb\\bar{b}\\bar{q}$. If a state around the estimated mass region could be observed, its nature as a genuine tetraquark is favored. The strong decay patterns shown here will be helpful to the experimental search for these exotic states.

Angelman syndrome (AS, OMIM105830) is a neurogenetic disorder caused by different genetic mechanisms. Determining the genetic mechanism is essential to establish the recurrence risk and the accuracy of genetic/reproductive counseling. The majority of AS patients present with a deletion of the 15q11.2-q13 region on the maternally derived chromosome. The other genetic mechanisms are: paternal disomy of chromosome 15, imprinting center defects, and mutations in the ubiquitin-protein ligase E3A gene (UBE3A). Different recurrence risks are associated with each specific genetic mechanism involved. We report on the study of dizygotic twins with classic phenotypic AS due to deletion of the same maternally derived chromosome 15. The mother presented with hypopigmented macular lesions on the inner side of both arms. Fibroblast culture studies of the maternal hypopigmented skin areas from both arms showed mosaicism for a normal cell line and for a second cell line with a 15q11.2-q13 deletion. This family represents the first demonstrated case of maternal somatic and germ line mosaicism for 15q11.2-q13 deletion as the cause of AS. © 2013 Wiley Periodicals, Inc.

A significant fraction of the hot Jupiters with final circularized orbital periods of less than 5 days are thought to form through the channel of high-eccentricity migration. Tidal dissipation at successive periastron passages removes orbital energy of the planet, which has the potential for changes in semi-major axis of a factor of ten to a thousand. In the equilibrium tide approximation we show that, in order for high-eccentricity migration to take place, the relative level of tidal dissipation in Jupiter analogues must be at least 10 times higher than the upper-limit attributed to the Jupiter-Io interaction. While this is not a severe problem for high-e migration, it contradicts the results of several previous calculations. We show that these calculations of high-e migration inadvertently over-estimated the strength of tidal dissipation by three to four orders of magnitude. These discrepancies were obscured by the use of various parameters, such as lag time \\tau, tidal quality factor Q and viscous time t_V...

Center of the universal Askey-Wilson algebra at roots of unity
Huang, Hau-Wen
2016-08-01
Inspired by a profound observation on the Racah-Wigner coefficients of Uq (sl2), the Askey-Wilson algebras were introduced in the early 1990s. A universal analog △q of the Askey-Wilson algebras was recently studied. For q not a root of unity, it is known that Z (△q) is isomorphic to the polynomial ring of four variables. A presentation for Z (△q) at q a root of unity is displayed in this paper. As an application, a presentation for the center of the double affine Hecke algebra of type (C1∨ ,C1) at roots of unity is obtained.

We report a new measurement of the exclusive electroproduction reaction gamma* p --> pi0 p to explore the evolution from soft non-perturbative physics to hard processes via the Q2 dependence of the magnetic (M1+), electric (E1+) and scalar (S1+) multipoles in the N --> Delta transition. 9000 differential cross section data points cover W from threshold to 1.4 GeV/c2, 4pi center-of-mass solid angle, and Q2 from 3 to 6 GeV2/c2, the highest yet achieved. It is found that the magnetic form factor G_{M}^{*} decreases with Q2 more steeply than the proton magnetic form factor, the ratio E1+/M1+ is small and negative, indicating strong helicity non-conservation, and the ratio S1+/M1+ is negative, while its magnitude increases with Q2.

Full Text Available Addressing the problems of a health care center which produces tailor-made clothes for specific people, the paper proposes a single product continuous review model and establishes an optimal policy for the center based on (Q,r control policy to minimize expected average cost on an order cycle. A generic mathematical model to compute cost on real-time inventory level is developed to generate optimal order quantity under stochastic stock variation. The customer demands are described as compound Poisson process. Comparisons on cost between optimization method and experience-based decision on Q are made through numerical studies conducted for the inventory system of the center.

The unstable branch is two fold: configurations with negative binding energy that collapse and form black holes, and others with positive binding energy that explode and release the scalar field.
Understanding Insight in the Context of Q
Coghlan, David
2012-01-01
In Revans' learning formula, L = P + Q, Q represents "questioning insight", by which Revans means that insight comes out of the process of questioning programmed knowledge (P) in the light of experience. We typically focus on the content of an insight rather than on the act of insight. Drawing primarily on the work of Bernard Lonergan this paper…

Full Text Available Meredith Spindler1, M Flint Beal1,2, Claire Henchcliffe1,21Department of Neurology, 2Department of Neuroscience, Weill Medical College of Cornell University, New York, NY, USAAbstract: Coenzyme Q10 (CoQ10 is an essential cofactor in the mitochondrial respiratory chain, and as a dietary supplement it has recently gained attention for its potential role in the treatment of neurodegenerative disease. Evidence for mitochondrial dysfunction in neurodegenerative disorders derives from animal models, studies of mitochondria from patients, identification of genetic defects in patients with neurodegenerative disease, and measurements of markers of oxidative stress. Studies of in vitro models of neuronal toxicity and animal models of neurodegenerative disorders have demonstrated potential neuroprotective effects of CoQ10. With this data in mind, several clinical trials of CoQ10 have been performed in Parkinson’s disease and atypical Parkinson’s syndromes, Huntington’s disease, Alzheimer disease, Friedreich’s ataxia, and amyotrophic lateral sclerosis, with equivocal findings. CoQ10 is widely available in multiple formulations and is very well tolerated with minimal adverse effects, making it an attractive potential therapy. Phase III trials of high-dose CoQ10 in large sample sizes are needed to further ascertain the effects of CoQ10 in neurodegenerative diseases.Keywords: coenzyme Q10, neurodegenerative disease, Parkinson’s disease, Huntington’s disease, mitochondrial dysfunction

q-Besselian Frames in Banach Spaces
Institute of Scientific and Technical Information of China (English)
Yu Can ZHU
2007-01-01
In this paper, we introduce the concepts of q-Besselian frame and (p, σ)-near Riesz basis in a Banach space, where σ is a finite subset of positive integers and 1/p + 1/q=1 with p 1, q 1, and determine the relations among q-frame, p-Riesz basis, q-Besselian frame and (p, σ)-near Riesz basis in a Banach space. We also give some sufficient and necessary conditions on a q-Besselian frame for a Banach space. In particular, we prove reconstruction formulas for Banach1 spaces X and X* that if {Xn}∞n=1(∪)X is a q-Besselian frame for X, then there exists a p-Besselian frame {y*n}∞n=1(∪) X* for X* such that x = ∑∞n-1 y*n(x)xn for all x ∈ X, and x = ∑∞n-1 x*xny*n, for all x* ∈ X*. Lastly, we consider the stability of a q-Besselian frame for the Banach space X under perturbation. Some results of J. R. Holub, P. G. Casazza, O. Christensen and others in Hilbert spaces are extended to Banach spaces.

Pure interstitial deletions of the long arm of chromosome 13 are correlated with variable phenotypes according to the size and the location of the deleted region. Deletions involving the 13q13q21 region are rare. In order to establish interstitial 13q genotype-phenotype correlation, we used high resolution 244K oligonucleotide array in addition to conventional karyotype and molecular (fluorescent in situ hybridization, microsatellite markers analysis) techniques in two independent probands carrying a deletion 13q13 to 13q21. First patient was a 3-year-old girl with mental retardation and dysmorphy carrying a 13q13.3q21.31 de novo deletion diagnosed post-natally. The second one was a fetus with de novo del(13)(q14q21.2) associated with first trimester increased nuchal translucency. We showed that specific dysmorphic features (macrocephaly, high forehead, hypertelorism, large nose, large and malformed ears and retrognathia) were correlated to the common 13q14q21 chromosomal segment. Physical examination revealed overgrowth with global measurement up to the 95th percentile in both probands. This is the second description of overgrowth in patients carrying a 13q deletion. Haploinsufficiency of common candidates genes such as CKAP2, SUGT1, LECT1, DCLK1 and SMAD9, involved in cell division and bone development, is a possible mechanism that could explain overgrowth in both patients. This study underlines also that cytogenetic analysis could be performed in patients with overgrowth.

The geographical distribution of Q fever.
KAPLAN, M M; BERTAGNA, P
1955-01-01
The results of a WHO-assisted survey of the distribution of Q fever in 32 countries and an analysis of reports published to date indicate that Q fever exists in 51 countries on five continents. Q-fever infection was most often reported in man and the domestic ruminants, such as cattle, sheep, and goats.The disease was found to exist in most countries where investigations were carried out. Notable exceptions were Ireland, the Netherlands, New Zealand, Poland, and the Scandinavian countries. With the exception of Poland, where the results were inconclusive, all these countries import relatively few domestic ruminants-the most important animal reservoirs of human Q-fever infection. It seems, therefore, that the traffic of infected ruminants may be one of the most important, if not the most important, means for the geographical spread of Q fever. The importance, if any, of ticks associated with such traffic needs to be defined.
Graded q-differential matrix algebra
Abramov, V.; Raknuzzaman, Md.
2013-10-01
We consider the algebra of square matrices of order N as graded q-differential algebra, where q is a primitive Nth root of unity. We study the differential calculus of this algebra determined by a differential d, which satisfies the graded q-Leibniz rule and dN = 0. A graded q-differential algebra can be viewed as a generalization of graded differential algebra, and we consider the higher degree elements of graded q-differential matrix algebra as analogs of differential forms. We use two matrices x,ξ, which generate the algebra of square matrices of order N in order to express these analogs of differential forms in terms of "coordinate" x and its differentials dx,d2x,...,dN-1x. We study an analog of connection and calculate its curvature.

This paper first presents the fundamental principles of the microwave photonic filters.As an example to explain how to implement a microwave photonic filter, a specific finite impulse response (FIR) filter is illustrated.Next, the Q value of the microwave photonic filters is analyzed theoretically, and methods around how to gain high Q value are discussed.Then,divided into FIR filter, first-order infinite impulse response (IIR) filter, and multi-order IIR filter, several novel microwave photonic filters with high Q value are listed and compared.The technical difficulties to get high Q value in first-order IIR filter and multi-order IIR filter are analyzed concretely.Finally, in order to gain higher Q value, a multi-order IIR microwave photonic filter that easily extends its order is presented and discussed.
Q factors for antennas in dispersive media
Gustafsson, Mats; Cismasu, Marius
2014-01-01
Stored energy and Q-factors are used to quantify the performance of small antennas. Accurate and efficient evaluation of the stored energy is also essential for current optimization and the associated physical bounds. Here, it is shown that the frequency derivative of the input impedance and the stored energy can be determined from the frequency derivative of the electric field integral equation. The expressions for the differentiated input impedance and stored energies differ by the use of a transpose and Hermitian transpose in the quadratic forms. The quadratic forms also provide simple single frequency formulas for the corresponding Q-factors. The expressions are further generalized to antennas integrated in temporally dispersive media. Numerical examples that compare the different Q-factors are presented for dipole and loop antennas in conductive, Debye, Lorentz, and Drude media. The computed Q-factors are also verified with the Q-factor obtained from the stored energy in Brune synthesized circuit models.

Coenzyme Q10 and male infertility.
Balercia, G; Mancini, A; Paggi, F; Tiano, L; Pontecorvi, A; Boscaro, M; Lenzi, A; Littarru, G P
2009-07-01
We had previously demonstrated that Coenzyme Q10 [(CoQ10) also commonly called ubiquinone] is present in well-measurable levels in human seminal fluid, where it probably exerts important metabolic and antioxidant functions; seminal CoQ10 concentrations show a direct correlation with seminal parameters (count and motility). Alterations of CoQ10 content were also shown in conditions associated with male infertility, such as asthenozoospermia and varicocele (VAR). The physiological role of this molecule was further clarified by inquiring into its variations in concentrations induced by different medical or surgical procedures used in male infertility treatment. We therefore evaluated CoQ10 concentration and distribution between seminal plasma and spermatozoa in VAR, before and after surgical treatment, and in infertile patients after recombinant human FSH therapy. The effect of CoQ10 on sperm motility and function had been addressed only through some in vitro experiments. In two distinct studies conducted by our group, 22 and 60 patients affected by idiopathic asthenozoospermia were enrolled, respectively. CoQ10 and its reduced form, ubiquinol, increased significantly both in seminal plasma and sperm cells after treatment, as well as spermatozoa motility. A weak linear dependence among the relative variations, at baseline and after treatment, of seminal plasma or intracellular CoQ10, ubiquinol levels and kinetic parameters was found in the treated group. Patients with lower baseline value of motility and CoQ10 levels had a statistically significant higher probability to be responders to the treatment. In conclusion, the exogenous administration of CoQ10 increases both ubiquinone and ubiquinol levels in semen and can be effective in improving sperm kinetic features in patients affected by idiopathic asthenozoospermia.
A new and unusual reciprocal translocation in cattle: rcp(11;25)(q11;q14-21).

A new and unusual reciprocal translocation was detected in a heifer of the Agerolese cattle breed during a routine cytogenetic screening carried out on 13 animals (2 males and 11 females) kept at the ConSDABI Conservation Center in Benevento (Southern Italy). The 13 animals investigated had a normal karyotype except for a 1-year-old female, which carried one autosome smaller than the smallest normal bovine autosomes. This small autosome showed very little C-banding in comparison to the other autosomes, while another medium-sized autosome showed 2 distinct and prominent C-bands. RBA-banding and karyotype analysis revealed that these 2 chromosomes were the result of a reciprocal translocation between chromosomes 11 and 25. FISH analysis with BAC142G06 mapping to the proximal (subcentromeric) region of both BTA25 and der11, BAC513H08 (ELN) mapping to BTA25q22dist and der25, and BAC533C11 mapping to the proximal region of BTA11 and der11 confirmed the localization of the breakpoints on band q11 (centromere) of chromosome 11 and q14-21 of chromosome 25. Ag-NOR and sequential RBA/Ag-NOR techniques detected the presence of NORs on both BTA11 and BTA25 and both der11 and der25. To our knowledge, this is the first report of a reciprocal translocation event in cattle with the breakpoint located in the centromeric region. Copyright © 2011 S. Karger AG, Basel.
De novo interstitial deletion q16.2q21 on chromosome 6
Energy Technology Data Exchange (ETDEWEB)
Villa, A.; Urioste, M.; Luisa, M. [Universidad Complutense, Madrid (Spain)] [and others
1995-01-30
A de novo interstitial deletion of 6q16.2q21 was observed in a 23-month-old boy with mental and psychomotor delay, obese appearance, minor craniofacial anomalies, and brain anomalies. We compare clinical manifestations of this patient with those observed in previously reported cases with similar 6q interstitial deletions. It is interesting to note the clinical similarities between some patients with interstitial deletions of 6q16 or q21 bands and patients with Prader-Willi syndrome (PWS) and it may help to keep in mind cytogenetic studies of patients with some PWS findings. 24 refs., 3 figs., 2 tabs.
Elliptic Quantum Groups U_{q,p}(gl_N) and E_{q,p}(gl_N)
Konno, Hitoshi
2016-01-01
We reformurate a central extension of Felder's elliptic quantum group in the FRST formulation as a topological algebra E_{q,p}(gl_N) over the ring of formal power series in p. We then discuss the isomorphism between E_{q,p}(gl_N) and the elliptic algebra U_{q,p}(gl_N) of the Drinfeld realization. An evaluation H-algebra homomorphism from U_{q,p}(gl_N) to a dynamical extension of the quantum affine algebra U_q(gl_N) resolves the problem into the one discussed by Ding and Frenkel in the trigonometric case. We also provide some useful formulas for the elliptic quantum determinants.

Absence of large-scale displacement of quinone QB in bacterial photosynthetic reaction centers.
Breton, Jacques
2004-03-30
Photosynthesis transforms light into chemical energy by coupling electron transfer to proton uptake at the quinone Q(B). The possibility of initiating this process with a brief pulse of light and the known X-ray structure makes the photosynthetic bacterial reaction center a paradigm for studying coupled electron-proton transfer in biology. It has been established that electron transfer from the primary quinone Q(A) to Q(B) is gated by a protein conformational change. On the basis of a dramatic difference in the location of Q(B) in structures derived from crystals cooled to 90 K either under illumination or in the dark, a functional model for the gating mechanism was proposed whereby neutral Q(B) moves 4.5 A before receiving the electron from Q(A)(-) [Stowell, M. H. B., McPhillips, T. M., Rees, D. C., Soltis, S. M., Abresch, E., and Feher, G. (1997) Science 276, 812-816]. Isotope-edited FTIR difference spectroscopy of Q(B) photoreduction at 290 and 85 K is used to investigate whether Q(B) moves upon reduction. We show that the specific interactions of the carbonyl groups of Q(B) and Q(B)(-) with the protein at a single binding site remain identical at both temperatures. Therefore, the different locations of Q(B) reported in many X-ray crystal structures probably are unrelated to functional electron transfer from Q(A)(-) to Q(B).
A case of de novo duplication of 15q24-q26.3
Directory of Open Access Journals (Sweden)
Hye Ran Kim
2011-06-01
Full Text Available Distal duplication, or trisomy 15q, is an extremely rare chromosomal disorder characterized by prenatal and postnatal overgrowth, mental retardation, and craniofacial malformations. Additional abnormalities typically include an unusually short neck, malformations of the fingers and toes, scoliosis and skeletal malformations, genital abnormalities, particularly in affected males, and, in some cases, cardiac defects. The range and severity of symptoms and physical findings may vary from case to case, depending upon the length and location of the duplicated portion of chromosome 15q. Most reported cases of duplication of the long arm of chromosome 15 frequently have more than one segmental imbalance resulting from unbalanced translocations involving chromosome 15 and deletions in another chromosome, as well as other structural chromosomal abnormalities. We report a female newborn with a de novo duplication, 15q24- q26.3, showing intrauterine overgrowth, a narrow asymmetric face with down-slanting palpebral fissures, a large, prominent nose, and micrognathia, arachnodactyly, camptodactyly, congenital heart disease, hydronephrosis, and hydroureter. Chromosomal analysis showed a 46,XX,inv(9(p12q13,dup(15(q24q26.3. Array comparative genomic hybridization analysis revealed a gain of 42 clones on 15q24-q26.3. This case represents the only reported patient with a de novo 15q24-q26.3 duplication that did not result from an unbalanced translocation and did not have a concomitant monosomic component in Korea.

In this paper we give a characterization of some classical q-orthogonal polynomials in terms of a difference property of the associated Stieltjes function, i.e this function solves a first order non-homogeneous q-difference equation. The solutions of the aforementioned q-difference equation (given in terms of hypergeometric series) for some canonical cases, namely, q-Charlier, q-Kravchuk, q-Meixner and q-Hahn are worked out.
On the Fock representation of the q-commutation relations
Dykema, K J; Dykema, Ken; Nica, Alexandru
1993-01-01
The q-commutation relations in the title are those that have recently received much attention, and that for -1<q<1 provide an interpolation between Bosonic and Fermionic statistics, passing through free statistics at q=0. We look at the C*-algebra R^q generated by the representation of these relations on the twisted Fock space of Bozejko-Speicher, and we find a canonical unitary U_q from the twisted Fock space to usual full Fock space, such that U_q R^q (U_q)^* contains the Cuntz algebra R^0, and such that we have equality for |q|<0.44.
Lateral and depth variations of coda Q in the Zagros region of Iran
Irandoust, Mohsen Ahmadzadeh; Sobouti, Farhad; Rahimi, Habib
2016-01-01
We have analyzed more than 2800 local earthquakes recorded by the Iranian National Seismic Network (INSN) and the Iranian Seismological Center (IRSC) to estimate coda wave quality factor, Q c , in the Zagros fold and thrust belt and the Sanandaj-Sirjan metamorphic zone in Iran. We used the single backscattering model to investigate lateral and depth variations of Q c in the study region. In the interior of Zagros, no strong lateral variation in attenuation parameters is observed. In SE Zagros (the Bandar-Abbas region) where transition to the Makran subduction setting begins, the medium shows lower attenuation. The average frequency relations for the SSZ, the Bandar-Abbas region, and the Zagros are Q c = (124 ± 11) f 0.82 ± 0.04, Q c = (109 ± 2) f 0.99 ± 0.01, and Q c = (85 ± 5) f 1.06 ± 0.03, respectively. To investigate the depth variation of Q c , 18 time windows between 5 and 90 s and at two epicentral distance ranges of R < 100 km and 100 < R < 200 km were considered. It was observed that with increasing coda lapse time, Q 0 ( Q c at 1 Hz) and n (frequency dependence factor) show increasing and decreasing trends, respectively. Beneath the SSZ and at depths of about 50 to 80 km, there is a correlation between the reported low velocity medium and the observed sharp change in the trend of Q 0 and n curves. In comparison with results obtained in other regions of the Iranian plateau, the Zagros along with the Alborz Mountains in the north show highest attenuation of coda wave and strongest frequency dependence, an observation that reflects the intense seismicity and active faulting in these mountain ranges. We also observe a stronger depth dependence of attenuation in the Zagros and SSZ compared to central Iran, indicating a thicker lithosphere in the Zagros region than in central Iran.
q-deformed Star Products and Moyal Brackets
Dayi, O F
1996-01-01
The standard and anti-standard ordered operators acting on two-dimensional q-deformed phase space are shown to satisfy algebras which can be called W_\\infty. q-star products and q-Moyal brackets corresponding to these algebras are constructed. Some applications like defining q-classical mechanics and q-path integrals are discussed.
Using Q Methodology in Quality Improvement Projects.
Tiernon, Paige; Hensel, Desiree; Roy-Ehri, Leah
Q methodology consists of a philosophical framework and procedures to identify subjective viewpoints that may not be well understood, but its use in nursing is still quite limited. We describe how Q methodology can be used in quality improvement projects to better understand local viewpoints that act as facilitators or barriers to the implementation of evidence-based practice. We describe the use of Q methodology to identify nurses' attitudes about the provision of skin-to-skin care after cesarean birth.

The first Forsmark potential repository site borehole KFM 01A provided core from 101.8 to 1000.7 m depth. This was independently Q-logged during a two-day period (19th-20th February, 2003), without access to BORMAP results or regional jointing frequencies or orientations. The Q-logging was intended to be an independent check for subsequent BORMAP-derived Q-parameter estimation. The Q-logging was accomplished using the manually-recorded 'histogram method' which allows the logger to enter Q-parameter ranges and depths directly into the appropriate histograms, which facilitates subsequent data processing using Excel spreadsheets. Successive pairs of core boxes, which contain an average of 11 meters of core in ten rows, were the source of ten opinions of each of the six Q-parameters, giving a total of 4920 recordings of Q-parameter values for the 164 core boxes. Data processing was divided into several parts, with successively increasing detail. The report therefore contains Q-histograms for the whole core, for four identified fracture(d) zones combined as if one unit, and then for the whole core minus these fracture(d) zones. This background rock mass quality is subsequently divided into nine depth zones or slices, and trends of variation with depth are tabulated. The four identified fracture(d) zones, which are actually of reasonable quality, are also analysed separately, and similarities and subtle differences are discerned between them. The overall quality of this first core is very good to excellent, with Q(mean) of 48.4, and a most frequent Q-value of 100. The range of quality is from 2.1 to 2130, which is the complete upper half of the six order of magnitude Q scale. Even the relatively fracture(d) zones, representing some 13% of the 900 m cored, have a combined Q(mean) of 13.9 and a range of quality of 2.1 to 150.
Inflation Driven by q-de Sitter
Setare, M. R.; Momeni, D.; Kamali, V.; Myrzakulov, R.

We propose a generalised de Sitter scale factor for the cosmology of early and late time universe, including single scalar field is called as inflaton. This form of scale factor has a free parameter q is called as nonextensivity parameter. When q = 1, the scale factor is de Sitter. This scale factor is an intermediate form between power-law and de Sitter. We study cosmology of such families. We show that both kinds of dark components, dark energy and dark matter simultaneously are described by this family of solutions. As a motivated idea, we investigate inflation in the framework of q-de Sitter. We consider three types of scenarios for inflation. In a single inflation scenario, we observe that, inflation ended without any specific ending inflation ϕ e n d , the spectral index and the associated running of the spectral index are n s - 1 ˜ -2 𝜖, α s ≡ 0. To end the inflation: we should have q={3}/{4}. We deduce that the inflation ends when the evolution of the scale factor is a( t) = e 3/4( t). With this scale factor there is no need to specify ϕ e n d . As an alternative to have inflation with ending point, We will study q-inflation model in the context of warm inflation. We propose two forms of damping term Γ. In the first case when Γ = Γ0, we show the scale invariant spectrum, (Harrison-Zeldovich spectrum, i.e. n s = 1) may be approximately presented by (q={9}/{10}, ~N=70). Also there is a range of values of R and n s which is compatible with the BICEP2 data where q={9}/{10}. In case Γ = Γ1 V( ϕ), it is observed that small values of a number of e-folds are assured for small values of q parameter. Also in this case, the scale-invariant spectrum may be represented by (q,N) = ({9}/{10},70). For q={9}/{10} a range of values of R and n s is compatible with the BICEP2 data. Consequently, the proposal of q-de Sitter is consistent with observational data. We observe that the non-extensivity parameter q plays a significant role in inflationary scenario.
The q-Laguerre matrix polynomials.
Salem, Ahmed
2016-01-01
The Laguerre polynomials have been extended to Laguerre matrix polynomials by means of studying certain second-order matrix differential equation. In this paper, certain second-order matrix q-difference equation is investigated and solved. Its solution gives a generalized of the q-Laguerre polynomials in matrix variable. Four generating functions of this matrix polynomials are investigated. Two slightly different explicit forms are introduced. Three-term recurrence relation, Rodrigues-type formula and the q-orthogonality property are given.

Misunderstandings about Q and 'Cochran's Q test' in meta-analysis.
Hoaglin, David C
2016-02-20
Many meta-analyses report using 'Cochran's Q test' to assess heterogeneity of effect-size estimates from the individual studies. Some authors cite work by W. G. Cochran, without realizing that Cochran deliberately did not use Q itself to test for heterogeneity. Further, when heterogeneity is absent, the actual null distribution of Q is not the chi-squared distribution assumed for 'Cochran's Q test'. This paper reviews work by Cochran related to Q. It then discusses derivations of the asymptotic approximation for the null distribution of Q, as well as work that has derived finite-sample moments and corresponding approximations for the cases of specific measures of effect size. Those results complicate implementation and interpretation of the popular heterogeneity index I(2) . Also, it turns out that the test-based confidence intervals used with I(2) are based on a fallacious approach. Software that outputs Q and I(2) should use the appropriate reference value of Q for the particular measure of effect size and the current meta-analysis. Q is a key element of the popular DerSimonian-Laird procedure for random-effects meta-analysis, but the assumptions of that procedure and related procedures do not reflect the actual behavior of Q and may introduce bias. The DerSimonian-Laird procedure should be regarded as unreliable.

The conjecture that several recently observed mesons have a structure, which is not dominated by an ordinary quark-antiquark pair, but by a four-quark structure, is being actively investigated both theoretical and experimentally. Such a state may be characterized as a mesonic molecule or as a diquark-antidiquark pair. Lattice QCD provides a theoretically sound framework to study such states. To quantitatively investigate the internal structure of such mesons, one needs to precisely compute correlation matrices containing several interpolating operators including two and four quarks. Here we discuss certain technical aspects of such correlation matrices suited to study tetraquark candidates with $J^P = 0^+$ and flavor structure $q_1 \\bar{q_2} q_3 \\bar{q}_3$, e.g.\\ the $a_0(980)$ meson, the $D_{s0}^\\ast$ meson and some of the charged $c \\bar{c}$ $X$ states. Some numerical results for the $a_0(980)$ meson are presented.

Skeletonized wave-equation inversion for Q
Dutta, Gaurav
2016-09-06
A wave-equation gradient optimization method is presented that inverts for the subsurface Q distribution by minimizing a skeletonized misfit function ε. Here, ε is the sum of the squared differences between the observed and the predicted peak/centroid frequency shifts of the early-arrivals. The gradient is computed by migrating the observed traces weighted by the frequency-shift residuals. The background Q model is perturbed until the predicted and the observed traces have the same peak frequencies or the same centroid frequencies. Numerical tests show that an improved accuracy of the inverted Q model by wave-equation Q tomography (WQ) leads to a noticeable improvement in the migration image quality.

In a recent paper Plastino and Rocca (2016) [18] we have demonstrated the possible existence of Tsallis' q-Gamow states. Now, accelerators' experimental evidence for Tsallis' distributions has been ascertained only at very high energies. Here, instead, we develop a different set of q-Gamow states for which the associated q-Breit–Wigner distribution could easily be found at intermediate energies, for which accelerators are available at many locations. In this context, it should be strongly emphasized Vignat and Plastino (2009) [2] that, empirically, one never exactly and unambiguously “detects” pure Gaussians, but rather q-Gaussians. A prediction is made via Eq. (3.4).

Chromosome 10q tetrasomy: First reported case
Energy Technology Data Exchange (ETDEWEB)

While there are several reports of trisomy 10q (at least 35), we are not aware of previous cases of 10q tetrasomy. We present what we believe to be the initial report of such a case. R.J. is a 6 1/2 year old white male who presented with multiple dysmorphic features, marked articulation problems, hyperactivity, and developmental delays. He is the product of a term uncomplicated pregnancy. There was a normal spontaneous vaginal delivery with a birth weight of 6 lbs. 4oz. and length was 19 1/2 inch. Dysmorphic features include small size, an asymmetrically small head, low set ears with overfolded helixes, bilateral ptosis, downslanting eyes, right eye esotropia, prominent nose, asymmetric facies, high palate, mild pectus excavatum deformity of chest, and hyperextensible elbow joints. The patient is in special needs classes for mildly mentally handicapped students. Chromosome analysis at a resolution of 800 bands revealed a complex rearrangement of chromosomes 10 and 11. The segment 10q25.3 to q16.3 appears to be inverted and duplicated within the long arm of chromosome 10 at band q25.3 and the same segment of chromosome 10 is present on the terminal end of the short arm of chromosome 11. There is no visible loss of material from chromosome 11. Fluorescence in situ hybridization was performed with a chromosome 10 specific {open_quotes}paint{close_quotes} to confirm that all of the material on the abnormal 10 and the material on the terminal short arm of 11 was from chromosome 10. Thus, it appears that the segment 10q25.3 to q26.3 is present in four copies. Parental chromosome studies are normal. We compared findings which differ in that the case of 10q tetrasomy did not have prenatal growth deficiency, microphthalmia, cleft palate, digital anomalies, heart, or renal defects. Whereas most cases of 10q trisomy are said to have severe mental deficiency, our case of 10q tetrasomy was only mildly delayed. We report this first apparent cited case of 10q tetrasomy.

The e^+p neutral-current deep inelastic scattering differential cross-sections $d\\sigma/dQ^2$, for Q^2 > 400 GeV^2, $d\\sigma/dx$ and $d\\sigma/dy$, for Q^2 > 400, 2500 and 10000 GeV^2, have been measured with the ZEUS detector at HERA. The data sample of 47.7 pb^-1 was collected at a center-of-mass energy of 300 GeV. The cross-section, $d\\sigma/dQ^2$, falls by six orders of magnitude between Q^2 = 400 and 40000 GeV^2. The predictions of the Standard Model are in very good agreement with the data. Complementing the observations of time-like Z^0 contributions to fermion-antifermion annihilation, the data provide direct evidence for the presence of Z^0 exchange in the space-like region explored by deep inelastic scattering.

We consider Friedberg-Lee-Sirlin Q-balls in a (3+1)-dimensional model with vanishing scalar potential of one of the fields. The Q-ball is stabilized by the gradient energy of this field and carries scalar charge, over and beyond the global charge. The latter property is inherent also in a model with the scalar potential that does not vanish in some finite field region near the origin.

Full Text Available In chronic lymphocytic leukemia (CLL, presence of acquired cytogenetic abnormalities may help to estimate prognosis. However, deletion of TP53 gene, which is associated with an aggressive course of the disease and poor prognosis along with a lack of response to treatment, is one of the alterations which may escape cytogenetic diagnoses in CLL. Thus, other techniques have emerged such as interphase fluorescence in situ hybridization (iFISH. Deletion of TP53 may but must not go together with the formation of an isochromosome i(17q; surprisingly this subgroup of patients was not in the focus of CLL studies yet. This study was about if presence of i(17q could be indicative for a new subgroup in CLL with more adverse prognosis. As a result, TP53 deletion was detected in 18 out of 150 (12% here studied CLL cases. Six of those cases (~33% had the TP53 deletion accompanied by an i(17q. Interestingly, the cases with i(17q showed a tendency towards more associated chromosomal aberrations. These findings may be the bases for follow-up studies in CLL patients with TP53 deletion with and without i(17q; it may be suggested that the i(17q presents an even more adverse prognostic marker than TP53 deletion alone.

Full Text Available Abstract Background Duplication of chromosome 15q11-q13 (dup15q accounts for approximately 3% of autism cases. Chromosome 15q11-q13 contains imprinted genes necessary for normal mammalian neurodevelopment controlled by a differentially methylated imprinting center (imprinting center of the Prader-Willi locus, PWS-IC. Maternal dup15q occurs as both interstitial duplications and isodicentric chromosome 15. Overexpression of the maternally expressed gene UBE3A is predicted to be the primary cause of the autistic features associated with dup15q. Previous analysis of two postmortem dup15q frontal cortical samples showed heterogeneity between the two cases, with one showing levels of the GABAA receptor genes, UBE3A and SNRPN in a manner not predicted by copy number or parental imprint. Methods Postmortem human brain tissue (Brodmann area 19, extrastriate visual cortex was obtained from 8 dup15q, 10 idiopathic autism and 21 typical control tissue samples. Quantitative PCR was used to confirm duplication status. Quantitative RT-PCR and Western blot analyses were performed to measure 15q11-q13 transcript and protein levels, respectively. Methylation-sensitive high-resolution melting-curve analysis was performed on brain genomic DNA to identify the maternal:paternal ratio of methylation at PWS-IC. Results Dup15q brain samples showed a higher level of PWS-IC methylation than control or autism samples, indicating that dup15q was maternal in origin. UBE3A transcript and protein levels were significantly higher than control and autism in dup15q, as expected, although levels were variable and lower than expected based on copy number in some samples. In contrast, this increase in copy number did not result in consistently increased GABRB3 transcript or protein levels for dup15q samples. Furthermore, SNRPN was expected to be unchanged in expression in dup15q because it is expressed from the single unmethylated paternal allele, yet SNRPN levels were significantly

In this paper,two kinds of skew derivations of a type of Nichols algebras are introduced,and then the relationship between them is investigated.In particular they satisfy the quantum Serre-relations.Therefore,the algebra generated by these derivations and corresponding automorphisms is a homomorphic image of the Drinfeld-Jimbo quantum enveloping algebra μq(g),which proves the Nichols algebra becomes aμq(g)-module algebra.But the Nichols algebra considered here is exactly μq+(g),namely,the positive part of the Drinfeld-Jimbo quantum enveloping algebra μq(g),it turns out that μq+(g)is a μq(g)-module algebra.

$q$-deformed Painleve tau function and q-deformed conformal blocks
Bershtein, M A
2016-01-01
We propose $q$-deformation of the Gamayun-Iorgov-Lisovyy formula for Painlev\\'e $\\tau$ function. Namely we propose formula for $\\tau$ function for $q$-difference Painlev\\'e equation corresponding to $A_7^{(1)}{}'$ surface (and $A_1^{(1)}$ symmetry) in Sakai classification. In this formula $\\tau$ function equals the series of $q$-Virasoro Whittaker conformal blocks (equivalently Nekrasov partition functions for pure $SU(2)$ 5d theory).
High rates of de novo 15q11q13 inversions in human spermatozoa

Full Text Available Abstract Low-Copy Repeats predispose the 15q11-q13 region to non-allelic homologous recombination. We have already demonstrated that a significant percentage of Prader-Willi syndrome (PWS fathers have an increased susceptibility to generate 15q11q13 deletions in spermatozoa, suggesting the participation of intrachromatid exchanges. This work has been focused on assessing the incidence of de novo 15q11q13 inversions in spermatozoa of control donors and PWS fathers in order to determine the basal rates of inversions and to confirm the intrachromatid mechanism as the main cause of 15q11q13 anomalies. Semen samples from 10 control donors and 16 PWS fathers were processed and analyzed by triple-color FISH. Three differentially labeled BAC-clones were used: one proximal and two distal of the 15q11-q13 region. Signal associations allowed the discrimination between normal and inverted haplotypes, which were confirmed by laser-scanning confocal microscopy. Two types of inversions were detected which correspond to the segments involved in Class I and II PWS deletions. No significant differences were observed in the mean frequencies of inversions between controls and PWS fathers (3.59% ± 0.46 and 9.51% ± 0.87 vs 3.06% ± 0.33 and 10.07% ± 0.74. Individual comparisons showed significant increases of inversions in four PWS fathers (P Results suggest that the incidence of heterozygous inversion carriers in the general population could reach significant values. This situation could have important implications, as they have been described as predisposing haplotypes for genomic disorders. As a whole, results confirm the high instability of the 15q11-q13 region, which is prone to different types of de novo reorganizations by intrachromatid NAHR.
The distribution of zeros of general q-polynomials
Álvarez-Nodarse, R.; Buendía, E.; Dehesa, J. S.
1997-10-01
A general system of q-orthogonal polynomials is defined by means of its three-term recurrence relation. This system encompasses many of the known families of q-polynomials, among them the q-analogue of the classical orthogonal polynomials. The asymptotic density of zeros of the system is shown to be a simple and compact expression of the parameters which characterize the asymptotic behaviour of the coefficients of the recurrence relation. This result is applied to specific classes of polynomials known by the names q-Hahn, q-Kravchuk, q-Racah, q-Askey and Wilson, Al Salam - Carlitz and the celebrated little and big q-Jacobi.

1993-01-01
We consider the q-deformed Knizhnik-Zamolodchikov equation for the two point function of q-deformed vertex operators of $U_q(sl_2^)$. We give explicitly the fundamental solutions, the connection matrices and the exchange relations for the q-vertex operators of spin 1/2 and $j \\in {1\\over 2}{\\bf Z}_{\\geq 0}$. Consequently, we confirm that the connection matrices are equivalent to the elliptic Boltzman weights of IRF type obtained by the fusion procedure from ABF models.

A balanced Robertsonian translocation 45,XY,t(15q15q) was detected in a patient with mental retardation, microcephaly, and hypertonia. Deletion of the 15q11q13 region was unlikely based on fluorescence in situ hybridization studies that revealed hybridization of appropriate DNA probes to both arms of the Robertsonian chromosome. Inheritance of alleles from 13 highly polymorphic DNA markers on chromosome 15 showed paternal uniparental isodisomy. The clinical, cytogenetic, and molecular results are consistent with a diagnosis of Angelman syndrome. 8 refs., 3 figs.

We describe three unrelated patients of European descent carrying an overlapping 3q26.33-3q27.2 microdeletion who share common clinical features: neonatal hypotonia, severe feeding problems, specific facial features, abnormal dentition, recurrent upper airways infections, developmental delay and severe growth impairment. One of the patients carries a smaller deletion and presents a milder phenotype. We propose that 3q26.33-3q27.2 microdeletion may represent a novel condition caused by the haploinsufficiency of dosage sensitive genes, several of which are involved in brain development.

The Quantum Superalgebra {{osp}q(1|2)} and a q-Generalization of the Bannai-Ito Polynomials
Genest, Vincent X.; Vinet, Luc; Zhedanov, Alexei
2016-06-01
The Racah problem for the quantum superalgebra {{osp}q(1|2)} is considered. The intermediate Casimir operators are shown to realize a q-deformation of the Bannai-Ito algebra. The Racah coefficients of {{osp}_q(1|2)} are calculated explicitly in terms of basic orthogonal polynomials that q-generalize the Bannai-Ito polynomials. The relation between these q-deformed Bannai-Ito polynomials and the q-Racah/Askey-Wilson polynomials is discussed.

In: S.G. Barwick and W.A. Jackson. Sublines and subplanes of PG(2,q^3) in the Bruck--Bose representation in PG(6,q). Finite Fields Th. App. 18 (2012) 93--107., the authors determine the representation of order-q-subplanes and order-q-sublines of PG(2,q^3) in the Bruck-Bose representation in PG(6,q). In particular, they showed that an order-q-subplane of PG(2,q^3) corresponds to a certain ruled surface in PG(6,q). In this article we show that the converse holds, namely that any ruled surface satisfying the required properties corresponds to a tangent order-q-subplane of PG(2,q^3).

Partial trisomy 9q34-qter and partial monosomy 8q24.3-qter are very rare chromosomal abnormalities. Characteristic features of partial trisomy 9q34-qter are hypotonia, developmental delay, mild intellectual disability, dolichocephaly, distinct facial phenotype, long and thin fingers, and cardiac anomalies. Unlike the partial trisomy 9q34-qter, partial monosomy 8q24.3-qter has no distinct phenotype. Here we report a four years old female patient with partial trisomy 9q34-qter and partial monosomy 8q24.3-qter due to the maternal translocation t(8;9)(q24.3;q34. I). She has developmental delay, brachycephaly, facial dysmorphism, hand and foot anomalies, bilateral hearing loss, cardiac defect and abnormal brain MRI findings. To the best of our knowledge, this is the first report of the combination of partial trisomy 9q and partial monosomy 8q.

In this paper we introduce two types of q-deformed Wigner algebras. One is q-deformation of Wigner algebra with q-reflection symmetry and another is q-deformation of Wigner algebra with reflection symmetry. For two types of q-deformed Wigner algebras, we investigate the representation and the eigenvalue of the position operator. Like q-calculus, we introduce the (q; ν)- numbers, (q; ν)-derivatives and (q; ν)-Hermite polynomials for two algebras. For the deformation parameter q = 1 - ε with small ε, we discuss the thermodynamics of the particle obeying the q-deformed Wigner algebra. (Copyright copyright 2014 WILEY-VCH Verlag GmbH and Co.

Background Duplications of 15q11.2-q13.1 (Dup15q syndrome) are highly penetrant for autism spectrum disorder (ASD). A distinct electrophysiological (EEG) pattern characterized by excessive activity in the beta band has been noted in clinical reports. We asked whether EEG power in the beta band, as well as in other frequency bands, distinguished children with Dup15q syndrome from those with non-syndromic ASD and then examined the clinical correlates of this electrophysiological biomarker in Dup15q syndrome. Methods In the first study, we recorded spontaneous EEG from children with Dup15q syndrome (n = 11), age-and-IQ-matched children with ASD (n = 10) and age-matched typically developing (TD) children (n = 9) and computed relative power in 6 frequency bands for 9 regions of interest (ROIs). Group comparisons were made using a repeated measures analysis of variance. In the second study, we recorded spontaneous EEG from a larger cohort of individuals with Dup15q syndrome (n = 27) across two sites and examined age, epilepsy, and duplication type as predictors of beta power using simple linear regressions. Results In the first study, spontaneous beta1 (12–20 Hz) and beta2 (20–30 Hz) power were significantly higher in Dup15q syndrome compared with both comparison groups, while delta (1–4 Hz) was significantly lower than both comparison groups. Effect sizes in all three frequency bands were large (|d| > 1). In the second study, we found that beta2 power was significantly related to epilepsy diagnosis in Dup15q syndrome. Conclusions Here, we have identified an electrophysiological biomarker of Dup15q syndrome that may facilitate clinical stratification, treatment monitoring, and measurement of target engagement for future clinical trials. Future work will investigate the genetic and neural underpinnings of this electrophysiological signature as well as the functional consequences of excessive beta oscillations in Dup15q syndrome.

Human Outer Solar System Exploration via Q-Thruster Technology
Joosten, B. Kent; White, Harold G.
2014-01-01
Propulsion technology development efforts at the NASA Johnson Space Center continue to advance the understanding of the quantum vacuum plasma thruster (QThruster), a form of electric propulsion. Through the use of electric and magnetic fields, a Q-thruster pushes quantum particles (electrons/positrons) in one direction, while the Qthruster recoils to conserve momentum. This principle is similar to how a submarine uses its propeller to push water in one direction, while the submarine recoils to conserve momentum. Based on laboratory results, it appears that continuous specific thrust levels of 0.4 - 4.0 N/kWe are achievable with essentially no onboard propellant consumption. To evaluate the potential of this technology, a mission analysis tool was developed utilizing the Generalized Reduced Gradient non-linear parameter optimization engine contained in the Microsoft Excel® platform. This tool allowed very rapid assessments of "Q-Ship" minimum time transfers from earth to the outer planets and back utilizing parametric variations in thrust acceleration while enforcing constraints on planetary phase angles and minimum heliocentric distances. A conservative Q-Thruster specific thrust assumption (0.4 N/kWe) combined with "moderate" levels of space nuclear power (1 - 2 MWe) and vehicle specific mass (45 - 55 kg/kWe) results in continuous milli-g thrust acceleration, opening up realms of human spaceflight performance completely unattainable by any current systems or near-term proposed technologies. Minimum flight times to Mars are predicted to be as low as 75 days, but perhaps more importantly new "retro-phase" and "gravity-augmented" trajectory shaping techniques were revealed which overcome adverse planetary phasing and allow virtually unrestricted departure and return opportunities. Even more impressively, the Jovian and Saturnian systems would be opened up to human exploration with round-trip times of 21 and 32 months respectively including 6 to 12 months of
Chromosome 15q24 microdeletion syndrome

Full Text Available Abstract Chromosome 15q24 microdeletion syndrome is a recently described rare microdeletion syndrome that has been reported in 19 individuals. It is characterized by growth retardation, intellectual disability, and distinct facial features including long face with high anterior hairline, hypertelorism, epicanthal folds, downslanting palpebral fissures, sparse and broad medial eyebrows, broad and/or depressed nasal bridge, small mouth, long smooth philtrum, and full lower lip. Other common findings include skeletal and digital abnormalities, genital abnormalities in males, hypotonia, behavior problems, recurrent infections, and eye problems. Other less frequent findings include hearing loss, growth hormone deficiency, hernias, and obesity. Congenital malformations, while rare, can be severe and include structural brain anomalies, cardiovascular malformations, congenital diaphragmatic hernia, intestinal atresia, imperforate anus, and myelomeningocele. Karyotypes are typically normal, and the deletions were detected in these individuals by array comparative genomic hybridization (aCGH. The deletions range in size from 1.7-6.1 Mb and usually result from nonallelic homologous recombination (NAHR between paralogous low-copy repeats (LCRs. The majority of 15q24 deletions have breakpoints that localize to one of five LCR clusters labeled LCR15q24A, -B, -C, -D, and -E. The smallest region of overlap (SRO spans a 1.2 Mb region between LCR15q24B to LCR15q24C. There are several candidate genes within the SRO, including CYP11A1, SEMA7A, CPLX3, ARID3B, STRA6, SIN3A and CSK, that may predispose to many of the clinical features observed in individuals with 15q24 deletion syndrome. The deletion occurred as a de novo event in all of the individuals when parents were available for testing. Parental aCGH and/or FISH studies are recommended to provide accurate genetic counseling and guidance regarding prognosis, recurrence risk, and reproductive options. Management
k and q Dedicated to Paul Callaghan
Blümich, Bernhard
2016-06-01
The symbols k and q denote wave numbers in scattering experiments as well as in NMR imaging. Their exploration in NMR is intimately linked to the legacy of Paul Callaghan with his books Magnetic Resonance Microscopy and Translational Dynamics & Magnetic Resonance (Oxford University Press, Oxford 1991 and 2011) placing their focus with their titles on k and q, respectively. Some aspects of k and q have been revisited in the Paul Callaghan lecture of the author at the ISMAR Conference in Shanghai in 2015, which are reviewed here. In particular, there are two definitions of q, one relating to diffusive displacement (q) and the other to coherent flow (qv). Concerning the latter, it turns out, that in the short gradient pulse limit, the common anti-phase pulsed field-gradient scheme can be replaced with schemes employing three and more gradient pulses, which derive from differentiation rules in numerical analysis. Practical gradient modulation schemes with finite gradient pulse widths follow from these to measure velocity with improved accuracy. This approach can be expanded to acceleration and higher order transport coefficients with applications to measurements of flow and potentially also restricted diffusion.
Chromosome 11q13 deletion syndrome
Kim, Yu-Seon; Kim, Gun-Ha; Byeon, Jung Hye; Eun, So-Hee
2016-01-01
Chromosome 11q13 deletion syndrome has been previously reported as either otodental syndrome or oculo-oto-dental syndrome. The otodental syndrome is characterized by dental abnormalities and high-frequency sensorineural hearing loss, and by ocular coloboma in some cases. The underlying genetic defect causing otodental syndrome is a hemizygous microdeletion involving the FGF3 gene on chromosome 11q13.3. Recently, a new form of severe deafness, microtia (small ear) and small teeth, without the appearance of eye abnormalities, was also reported. In this report, we describe a 1-year-old girl presenting with ptosis of the left upper eyelid, right auricular deformity, high-arched palate, delayed dentition, simian line on the right hand, microcephaly, and developmental delay. In this patient, we identified a deletion in the chromosome 11q13.2-q13.3 (2.75 Mb) region by using an array-comparative genomic hybridization analysis. The deletion in chromosome 11q13 results in a syndrome characterized by variable clinical manifestations. Some of these manifestations involve craniofacial dysmorphology and require a functional workup for hearing, ophthalmic examinations, and long-term dental care. PMID:28018436

Characterization of a balanced reciprocal translocation, rcp(9;11)(q27;q11) in cattle.
De Lorenzi, L; De Giovanni, A; Molteni, L; Denis, C; Eggen, A; Parma, P
2007-01-01
Cytogenetic analysis of a phenotypically normal young bull from Marchigiana breed revealed the presence of an abnormal karyotype. The observation of longer and smaller chromosomes than BTA1 and BTA29, respectively in all metaphases suggested the presence of a reciprocal translocation. RBG-banding confirmed this hypothesis revealing the involvement of BTA9 and BTA11. FISH analyses using cattle-specific BAC clones (474A12 and 293G09 for BTA9; 035D03 for BTA11) identified rcp(9;11)(q27;q11) in the two regions affected. Moreover analyses performed on both parents established the 'de novo' origin of the anomaly. Comparison with human homologue sequences (HSA6q24.3-->q25.3 for BTA9q27 and HSA2q11.1-->q12.1 for BTA11q11) revealed that both breakpoint regions are gene rich as up to date at least 200 genes have been localized in these regions. Thus, further analyses are required to identify the sequences disrupted by the breakpoints and to verify their consequences on rcp carrier phenotype. Copyright (c) 2008 S. Karger AG, Basel.

In comparing the particle flow in the event plane of three-jet (q anti qg) events and of radiative annihilation events (q anti q..gamma..) for similar kinematic configurations, two PEP experiments find a significant decrease in particle density in the angular region opposite to the gluon jet in q anti qg events, relative to the particle density in the region opposite to the photon in q anti q..gamma.. events. The effect is predicted both by QCD and by phenomenological string models. 5 refs., 5 figs.

Baxter's Q-operator is generally believed to be the most powerful tool for the exact diagonalization of integrable models. Curiously, it has hitherto not yet been properly constructed in the simplest such system, the compact spin-1/2 Heisenberg-Bethe XXX spin chain. Here we attempt to fill this gap and show how two linearly independent operatorial solutions to Baxter's TQ equation may be constructed as commuting transfer matrices if a twist field is present. The latter are obtained by tracing over infinitely many oscillator states living in the auxiliary channel of an associated monodromy matrix. We furthermore compare and differentiate our approach to earlier articles addressing the problem of the construction of the Q-operator for the XXX chain. Finally we speculate on the importance of Q-operators for the physical interpretation of recent proposals for the Y-system of AdS/CFT.

We develop methodology for a multistage decision problem with flexible number of stages in which the rewards are survival times that are subject to censoring. We present a novel Q-learning algorithm that is adjusted for censored data and allows a flexible number of stages. We provide finite sample bounds on the generalization error of the policy learned by the algorithm, and show that when the optimal Q-function belongs to the approximation space, the expected survival time for policies obtained by the algorithm converges to that of the optimal policy. We simulate a multistage clinical trial with flexible number of stages and apply the proposed censored-Q-learning algorithm to find individualized treatment regimens. The methodology presented in this paper has implications in the design of personalized medicine trials in cancer and in other life-threatening diseases.

A new generation of highly selective short-pulsed lasers has emerged in recent years for the treatment of tattoos. Several studies (including reports by the present investigators) have proven the efficacy of each of the three commercially available, FDA approved devices; namely, the Q-switched alexandrite, Q-switched Nd:YAG and Q-switched ruby lasers. Considerable differences among the three have been reported in relation to the rate of clearing of the tattoo ink particles, tissue effects, beam profile, wound healing, and side effects. This study was primarily conducted to examine and compare the clinical response of patients with blue-black tattoos simultaneously treated with three different Q-switched lasers (alexandrite, Nd:YAG, ruby) with a focus on the percentage of tattoo lightening/clearance and the occurrence or non-occurrence of pigmentary change as a side effect. A total of forty-two blue-black tattoos seen at two laser centers (Massachusetts General Hospital Dermatology Laser Center and Laser and Skin Surgery Center of La Jolla) were simultaneously treated with three types of Q-switched lasers: a Candela Q-switched alexandrite laser (755nm 50-100 nanoseconds, 3.0 mm spot size, 6-8 J/cm2); a Continuum Biomedical Q-switched Nd:YAG laser (1064nm, 10-20 nanoseconds, 3.0 mm spot size, 5-10 J/cm2); and a Spectrum Q-switched ruby laser (694 nm, 25-40 nanoseconds, 5.0 mm spot size, 4-10 J/cm2). Paired t-tests and McNemar tests were used to compare the treatment outcome and pigmentation side effects between sites per tattoo, with each site representative of one of the three lasers. The statistical significance level was set at p tattoo lightening versus the Q-switched Nd:YAG and Q-switched alexandrite lasers. An increase in the number of treatments paralleled a statistically significant increase in tattoo clearance for all three Q-switched lasers. The Q-switched ruby laser had the highest clearance rate in blue-black tattoos and the highest incidence of long
Indecomposable U_q(sl_n) modules for q^h = -1 and BRS intertwiners
Furlan, Paolo; Todorov, I G; Furlan, Paolo; Hadjiivanov, Ludmil; Todorov, Ivan
2001-01-01
A class of indecomposable representations of U_q(sl_n) is considered for q an even root of unity (q^h = -1) exhibiting a similar structure as (height h) indecomposable lowest weight Kac-Moody modules associated with a chiral conformal field theory. In particular, U_q(sl_n) counterparts of the Bernard-Felder BRS operators are constructed for n=2,3. For n=2 a pair of dual d_2(h) = h dimensional U_q(sl_2) modules gives rise to a 2h-dimensional indecomposable representation including those studied earlier in the context of tensor product expansions of irreducible representations. For n=3 the interplay between the Poincare'-Birkhoff-Witt and (Lusztig) canonical bases is exploited in the study of d_3(h) = h(h+1)(2h+1)/6 dimensional indecomposable modules and of the corresponding intertwiners.

Recently, a novel pathway for heme b biosynthesis in Gram-positive bacteria has been proposed. The final poorly understood step is catalyzed by an enzyme called HemQ and includes two decarboxylation reactions leading from coproheme to heme b. Coproheme has been suggested to act as both substrate and redox active cofactor in this reaction. In the study presented here, we focus on HemQs from Listeria monocytogenes (LmHemQ) and Staphylococcus aureus (SaHemQ) recombinantly produced as apoproteins in Escherichia coli. We demonstrate the rapid and two-phase uptake of coproheme by both apo forms and the significant differences in thermal stability of the apo forms, coproheme-HemQ and heme b-HemQ. Reduction of ferric high-spin coproheme-HemQ to the ferrous form is shown to be enthalpically favored but entropically disfavored with standard reduction potentials of -205 ± 3 mV for LmHemQ and -207 ± 3 mV for SaHemQ versus the standard hydrogen electrode at pH 7.0. Redox thermodynamics suggests the presence of a pronounced H-bonding network and restricted solvent mobility in the heme cavity. Binding of cyanide to the sixth coproheme position is monophasic but relatively slow (∼1 × 10(4) M(-1) s(-1)). On the basis of the available structures of apo-HemQ and modeling of both loaded forms, molecular dynamics simulation allowed analysis of the interaction of coproheme and heme b with the protein as well as the role of the flexibility at the proximal heme cavity and the substrate access channel for coproheme binding and heme b release. Obtained data are discussed with respect to the proposed function of HemQ in monoderm bacteria.
Steps toward increasing Q in mirror systems

Experiments such as the 2XIIB experiment at Livermore have established the ability of mirror systems to confine high temperature, high density plasmas at central beta values exceeding unity. Given these results the next tasks for the mirror approach are to explore means for increasing the energy gain factor Q and to scale up the plasma volume, both of these requirements deriving from economic constraints. This report discusses means for increasng Q, including recent improvements in the tandem mirror concept and design studies of the field-reversed mirror in the context of upcoming and proposed scaled-up mirror experiments.
Levin, A.; Rubakov, V.
We consider Friedberg-Lee-Sirlin Q-balls in a (3+1)-dimensional model with vanishing scalar potential of one of the fields. We show that, unlike in (2+1) and (1+1) dimensions, the Q-ball is stabilized by the gradient energy of this field and carries scalar charge, over and beyond the global charge. The latter property is also inherent in a model with the scalar potential that does not vanish in a finite field region near the origin.
[Q fever, a zoonosis often overlooked].
Delaloye, J; Greub, G
2013-04-24
Q fever is a zoonosis caused by an intracellular Gram-negative bacteria, Coxiella burnetii. Animals are the main reservoir and transmission to men generally is occurring by inhalation of contaminated aerosols. Acute Q fever generally is benign and usually resolves spontaneously. When symptomatic, the clinical presentation typically includes one of the following three syndromes: a flu-like illness, a granulomatous hepatitis or an atypical pneumonia. Individuals presenting risk factors such as patients with valvular heart diseases and vascular prostheses, as well as pregnant women and immuno-suppressed patients represent a population at risk of chronic infection, with endocarditis as the most common clinical form.

A covariant spectator quark model is applied to study the gamma N -> N*(1535) reaction in the large Q2 region. Starting from the relation between the nucleon and N*(1535) systems, the N*(1535) valence quark wave function is determined without the addition of any parameters. The model is then used to calculate the gamma N -> N*(1535) transition form factors. A very interesting, useful relation between the A12 and S12 helicity amplitudes for Q2 > GeV^2, is also derived.

Q-enhanced racetrack micro-resonators
Chamorro-Posada, Pedro
2016-01-01
A Q enhancement strategy for racetrack micro -resonators is put forward. The design is based on the modification of the resonator geometry in order to mitigate the two main sources of radiation loss in the presence of curved waveguides: the couplings from the straight waveguides to the bent sections and the continuous loss at the curved waveguide sectors. Numerical calculations show over $100\\%$ improvement of the Q factor in silicon nitride resonators. At the same time, the modifications of the geometry do not affect the coupling properties of the resonators in integrated optical circuits.
Biomedical Technology Assessment The 3Q Method

2010-01-01
Evaluating biomedical technology poses a significant challenge in light of the complexity and rate of introduction in today's healthcare delivery system. Successful evaluation requires an integration of clinical medicine, science, finance, and market analysis. Little guidance, however, exists for those who must conduct comprehensive technology evaluations. The 3Q Method meets these present day needs. The 3Q Method is organized around 3 key questions dealing with 1) clinical and scientific basis, 2) financial fit and 3) strategic and expertise fit. Both healthcare providers (e.g., hospitals) an
Multi-indexed (q)-Racah Polynomials

2012-01-01
As the second stage of the project $multi-indexed orthogonal polynomials$, we present, in the framework of `discrete quantum mechanics' with real shifts in one dimension, the multi-indexed (q)-Racah polynomials. They are obtained from the (q)-Racah polynomials by multiple application of the discrete analogue of the Darboux transformations or the Crum-Krein-Adler deletion of `virtual state' vectors of type I and II, in a similar way to the multi-indexed Laguerre and Jacobi polynomials reported earlier. The virtual state vectors are the `solutions' of the matrix Schr\\"odinger equation with negative `eigenvalues', except for one of the two boundary points.

We study the effect of menu costs on the pricing behavior of sellers and on the cross-sectional distribution of prices in the search-theoretic model of imperfect competition of Burdett and Judd (1983). We find that, when menu costs are small, the equilibrium is such that sellers follow a (Q, S, s) pricing rule. According to a (Q, S, s) rule, a seller lets inflation erode the real value of its nominal price until it reaches some point s. Then, the seller pays the menu cost and changes its nomi...

As part of the Saltstone formulation work requested by Waste Solidification Engineering (WSE), Savannah River National Laboratory (SRNL) was tasked with preparing Saltstone samples for fresh property analysis and hydraulic conductivity measurements using actual Tank 50 salt solution rather than simulated salt solution. Samples of low level waste salt solution collected from Tank 50H during the first, second, and third quarters of 2011 were used to formulate the Saltstone samples. The salt solution was mixed with premix (45 wt % slag, 45 wt % fly ash, and 10 wt % cement), in a ratio consistent with facility operating conditions during the quarter of interest. The fresh properties (gel, set, bleed) of each mix were evaluated and compared to the recommended acceptance criteria for the Saltstone Production Facility. ASTM D5084-03, Method C was used to measure the hydraulic conductivity of the Saltstone samples. The hydraulic conductivity of Saltstone samples prepared from 1Q11 and 2Q11 samples of Tank 50H is 4.2E-9 cm/sec and 2.6E-9 cm/sec, respectively. Two additional 2Q11 and one 3Q11 sample were not successfully tested due to the inability to achieve stable readings during saturation and testing. The hydraulic conductivity of the samples made from Tank 50H salt solution compare well to samples prepared with simulated salt solution and cured under similar conditions (1.4E-9 - 4.9E-8 cm/sec).

Acute promyelocytic leukemia (APL) is characterized by the t(15;17)(q22;q21), which results in the fusion of the promyelocytic leukemia (PML) gene at 15q22 with the retinoic acid alpha-receptor (RARA) at 17q21. We report the case of a 44-year-old man with APL carrying a new complex variant translocation (15;22;17). Karyotypic analysis with G-banding of bone marrow cells revealed t(15;22;17) (q22;q11.2;q21). Fluorescence in situ hybridization with a PML/RARA dual-color DNA probe showed the fusion signals. RT-PCR analysis showed long-form PML/RARA fusion transcripts. A complete remission was attained with a course of conventional chemotherapy with all-trans retinoic acid (ATRA). This is the first report of a new three-way translocation of 22q11 involvement with APL.

Center separation defect of Q345B thick plates was investigated.The results show that the heavy center porosity carried over from continuous cast 320 mm thick mother slabs is the key reason for center separation defect.Analysis on soft reduction for the slabs indicates that the actual crater end is further down the strand than the calculated position from previous online solidification model,and hence,the reduction ratio is insufficient at the final stage of solidification to compensate the final solidification shrinkage.Based on the investigation and analysis,the soft reduction scheme is optimized by extending soft reduction range and increasing the reduction ratio at the final solidification stage.After the optimization,center porosity and center segregation in the slabs are alleviated,and the center separation defect in the thick Q345B plates is resolved.%针对生产中出现的厚规格Q345B板材厚度中心分层缺陷进行了调查分析,结果表明：板材中心分层是由于连铸坯中较为严重的中心疏松在后期轧制过程中未能轧合所致。进一步对Q345B连铸坯轻压下工艺调查发现,实际凝固终点位置比模型计算值靠后,且凝固末端扇形段压下率低,不足以补偿其凝固收缩,从而形成较为严重的中心疏松缺陷。在调查分析基础上,通过将该规格连铸坯轻压下区间后延并加大轻压下量,增加了凝固末端压下率,降低了连铸坯中心疏松和中心偏析程度,从而彻底解决了板材中心分层问题。

Interstitial deletions of chromosomal region 9q are rarely seen. We report the first prenatal diagnosis of a de novo interstitial deletion 9q. The fetus was karyotyped for intrauterine growth retardation (IUGR). Conventional and molecular cytogenetics showed female karyotype with a de novo deletion of the chromosomal region 9(q22.2q31.1) leading to a partial monosomy 9q. At autopsy, the fetus showed growth retardation, dysmorphy, and a female pseudohermaphroditism. These results suggest that a gene(s) for genital development reside in chromosomal region 9q22.2q31.1.

New multi-level codes over GF(q)
Wu, Jiantian; Costello, Daniel J., Jr.
1990-01-01
Set partitioning to multi-dimensional signal spaces over GF(q), particularly GF sup q-1(q) and GF sup q (q), and show how to construct both multi-level block codes and multi-level trellis codes over GF(q). Two classes of multi-level (n, k, d) block codes over GF(q) with block length n, number of information symbols k, and minimum distance d sub min greater than or = d, are presented. These two classes of codes use Reed-Solomon codes as component codes. They can be easily decoded as block length q-1 Reed-Solomon codes or block length q or q + 1 extended Reed-Solomon codes using multi-stage decoding. Many of these codes have larger distances than comparable q-ary block codes, as component codes. Low rate q-ary convolutional codes, work error correcting convolutional codes, and binary-to-q-ary convolutional codes can also be used to construct multi-level trellis codes over GF(q) or binary-to-q-ary trellis codes, some of which have better performance than the above block codes. All of the new codes have simple decoding algorithms based on hard decision multi-stage decoding.

The 2q3 duplication and 4q3 deletion are two distinct conditions with variable phenotypes including developmental delay, intellectual disability, Pierre Robin sequence (PRS), and cardiovascular, craniofacial, digital and skeletal anomalies. We describe two cousins, a 37-year-old man (Patient 1) and a 17-year-old girl (Patient 2), with a derivative chromosome leading to a 4q35 deletion-2q35q37 duplication. Conventional karyotype showed in both patients the same rearrangement derived from unbalanced segregation of a parental reciprocal translocation involving the long arms of chromosome 2 and 4. Patient 1's father and Patient 2's mother were identified as the carriers of a balanced translocation t(2;4)(q35;q35). Array-CGH analysis, performed to characterize the rearrangement, documented in both patients the presence of a 26 Mb duplication of the 2q35-q37.3 region of chromosome 2 and a 6.3 Mb deletion of the 4q35.1-q35.2 region of chromosome 4. Both patients showed intellectual disability, minor facial, and digital anomalies, hearing, ocular, and genitourinary abnormalities. The comparison of their features with those of published cases of 2q3 duplication and 4q3 deletion allowed us to further delineate the genotype-phenotype correlation as well as the combined effect of partial 2q duplication and 4q deletion syndromes in adulthood.
Extended q-Gaussian and q-exponential distributions from gamma random variables.
Budini, Adrián A
2015-05-01
The family of q-Gaussian and q-exponential probability densities fit the statistical behavior of diverse complex self-similar nonequilibrium systems. These distributions, independently of the underlying dynamics, can rigorously be obtained by maximizing Tsallis "nonextensive" entropy under appropriate constraints, as well as from superstatistical models. In this paper we provide an alternative and complementary scheme for deriving these objects. We show that q-Gaussian and q-exponential random variables can always be expressed as a function of two statistically independent gamma random variables with the same scale parameter. Their shape index determines the complexity q parameter. This result also allows us to define an extended family of asymmetric q-Gaussian and modified q-exponential densities, which reduce to the standard ones when the shape parameters are the same. Furthermore, we demonstrate that a simple change of variables always allows relating any of these distributions with a beta stochastic variable. The extended distributions are applied in the statistical description of different complex dynamics such as log-return signals in financial markets and motion of point defects in a fluid flow.

Quality Metric Development Framework (qMDF
Directory of Open Access Journals (Sweden)
K. Mustafa
2005-01-01
Full Text Available Several object-oriented metrics have been developed and used in conjunction with the quality models to predict the overall quality of software. However, it may not be enough to propose metrics. The fundamental question may be of their validity, utility and reliability. It may be much significant to be sure that these metrics are really useful and for that their construct validity must be assured. Thereby, good quality metrics must be developed using a foolproof and sound framework / model. A critical review of literature on the attempts in this regard reveals that there is no standard framework or model available for such an important activity. This study presents a framework for the quality metric development called Metric Development Framework (qMDF, which is prescriptive in nature. qMDF is a general framework but it has been established specially with ideas of object-oriented metrics. qMDF has been implemented to develop a good quality design metric, as a validation of proposed framework. Finally, it is defended that adaptation of qMDF by metric developers would yield good quality metrics, while ensuring their construct validity, utility, reliability and reduced developmental effort.

Starting from the idea of Tsallis on non-extensive statistical mechanics and the {\\it q-entropy} notion, we recall the Theil index $Th$ and transform it into the $Th_q$ index. Both indices can be used to map onto themselves any time series in a non linear way. We develop an application of the $Th_q$ to the GDP evolution of 20 rich countries in the time interval [1950 - 2003] and search for a proof of globalization of their economies. First we calculate the distances between the "new" time series and to their mean, from which such data simple networks are constructed. We emphasize that it is useful to, and we do, take into account different time "parameters": (i) the moving average time window for the raw time series to calculate the $Th_q$ index; (ii) the moving average time window for calculating the time series distances; (iii) a correlation time lag. This allows us to deduce optimal conditions to measure the features of the network, i.e. the appearance in 1970 of a globalization process in the economy of s...

Reliable Q estimation is desirable for model-based inverse Q filtering to improve seismic resolution. On the one hand, conventional methods estimate Q from the amplitude spectra or frequency variations of individual wavelets at different depth (or time) levels, which is vulnerable to the effects of spectral interference and ambient noise. On the other hand, most inverse Q filtering algorithms are sensitive to noise, in order not to boost them, sometimes at the expense of degrading compensation effect. In this paper, the average-Q values are obtained from reflection seismic data based on the Gabor transform spectrum of a seismic trace. We transform the 2-D time-variant frequency spectrum into the 1-D spectrum, and then estimate the average-Q values based on the amplitude attenuation and compensation functions, respectively. Driven by the estimated average-Q model, we also develop a modified inverse Q filtering algorithm by incorporating a time-variant bandpass filter (TVBF), whose high cut off frequency follows a hyperbola along the traveltime from a specified time. Finally, we test this modified inverse Q filtering algorithm on synthetic data and perform the Q estimation procedure on a real reflection seismic data, followed by applying the modified inverse Q filtering algorithm. The synthetic data test and the real data example demonstrate that the algorithm driven by average-Q model may enhance the seismic resolution, without degrading the signal-to-noise ratio.

Full Text Available Coenzyme Q10 (CoQ10 is a naturally occurring, lipid soluble, essential compound and is also known as ubiquinone. CoQ10 acts as an intermediate of the electron transport chain situated in membrane of mitochondria and vital for ATP production and cellular respiration. CoQ10 also serves as an intercellular antioxidant. All the clinical use of CoQ10 are based upon these two functions. CoQ10 levels are altered in a number of oncological as well as non-oncological diseases. Furthermore, recent data indicate that CoQ10 has an impact on the expression of many genes involved in metabolism, cellular transport, transcription control, and cell signaling, making CoQ10 a potent gene regulator. CoQ10 supplementation is useful in diseases associated with CoQ10 deficiency which includes primary and secondary CoQ10 deficiencies, fibromyalgia, diabetes mellitus, mitochondrial diseases, neurodegenerative diseases, cardiovascular disease, cancer, male infertility and periodontal disease. Clinical presentations of severe CoQ10 deficiency include severe infantile multisystemic disease, encephalomyopathy, isolated myopathy cerebellar ataxia and Leigh syndrome with growth retardation. Oral CoQ10 administration can correct CoQ10 deficiency since it increases CoQ10 tissue levels. CoQ10 therapy has no serious side effects in humans and new formulations have been developed that increase CoQ10 absorption and tissue distribution. Future trends involving CoQ10 in many diseases needs more clinical trials for better understanding of CoQ10 efficacy. [Int J Res Med Sci 2015; 3(4.000: 817-825

Autism is a complex disorder characterized by genetic and phenotypic heterogeneity. Analysis of phenotypically homogeneous subtypes has been used to both confirm and narrow potential autism linkage regions such as the chromosomal region 15q11-q13. Increased evidence for linkage in this region had been found in a subgroup of 21 autism families (total families = 94) stratified based on a savant skill factor (SSF) from the Autism Diagnostic Interview, Revised (ADI-R). We examined the savant phenotypic finding in our sample of 91 multiplex autism families. Using two-point parametric analysis in stratification with a cutoff point of a savant skill score of 0.16, our families failed to demonstrate linkage to 15q11-q13. In addition, ordered subset analysis (OSA) using SSF as a covariate also failed to show evidence for linkage. Our findings do not support savant skills as an informative phenotypic subset for linkage in our sample.

Full Text Available Abstract The deletion 22q13.3 syndrome (deletion 22q13 syndrome or Phelan-McDermid syndrome is a chromosome microdeletion syndrome characterized by neonatal hypotonia, global developmental delay, normal to accelerated growth, absent to severely delayed speech, and minor dysmorphic features. The deletion occurs with equal frequency in males and females and has been reported in mosaic and non-mosaic forms. Due to lack of clinical recognition and often insufficient laboratory testing, the syndrome is under-diagnosed and its true incidence remains unknown. Common physical traits include long eye lashes, large or unusual ears, relatively large hands, dysplastic toenails, full brow, dolicocephaly, full cheeks, bulbous nose, and pointed chin. Behavior is autistic-like with decreased perception of pain and habitual chewing or mouthing. The loss of 22q13.3 can result from simple deletion, translocation, ring chromosome formation and less common structural changes affecting the long arm of chromosome 22, specifically the region containing the SHANK3 gene. The diagnosis of deletion 22q13 syndrome should be considered in all cases of hypotonia of unknown etiology and in individuals with absent speech. Although the deletion can sometimes be detected by high resolution chromosome analysis, fluorescence in situ hybridization (FISH or array comparative genomic hybridization (CGH is recommended for confirmation. Differential diagnosis includes syndromes associated with hypotonia, developmental delay, speech delay and/or autistic-like affect (Prader-Willi, Angelman, Williams, Smith-Magenis, Fragile X, Sotos, FG, trichorhinophalangeal and velocardiofacial syndromes, autism spectrum disorders, cerebral palsy. Genetic counseling is recommended and parental laboratory studies should be considered to identify cryptic rearrangements and detect parental mosaicism. Prenatal diagnosis should be offered for future pregnancies in those families with inherited rearrangements

Genetic bases and clinical manifestations of coenzyme Q10 (CoQ 10) deficiency.
Desbats, Maria Andrea; Lunardi, Giada; Doimo, Mara; Trevisson, Eva; Salviati, Leonardo
2015-01-01
Coenzyme Q(10) is a remarkable lipid involved in many cellular processes such as energy production through the mitochondrial respiratory chain (RC), beta-oxidation of fatty acids, and pyrimidine biosynthesis, but it is also one of the main cellular antioxidants. Its biosynthesis is still incompletely characterized and requires at least 15 genes. Mutations in eight of them (PDSS1, PDSS2, COQ2, COQ4, COQ6, ADCK3, ADCK4, and COQ9) cause primary CoQ(10) deficiency, a heterogeneous group of disorders with variable age of onset (from birth to the seventh decade) and associated clinical phenotypes, ranging from a fatal multisystem disease to isolated steroid resistant nephrotic syndrome (SRNS) or isolated central nervous system disease. The pathogenesis is complex and related to the different functions of CoQ(10). It involves defective ATP production and oxidative stress, but also an impairment of pyrimidine biosynthesis and increased apoptosis. CoQ(10) deficiency can also be observed in patients with defects unrelated to CoQ(10) biosynthesis, such as RC defects, multiple acyl-CoA dehydrogenase deficiency, and ataxia and oculomotor apraxia.Patients with both primary and secondary deficiencies benefit from high-dose oral supplementation with CoQ(10). In primary forms treatment can stop the progression of both SRNS and encephalopathy, hence the critical importance of a prompt diagnosis. Treatment may be beneficial also for secondary forms, although with less striking results.In this review we will focus on CoQ(10) biosynthesis in humans, on the genetic defects and the specific clinical phenotypes associated with CoQ(10) deficiency, and on the diagnostic strategies for these conditions.

Segmental maternal uniparental disomy 7q associated with DLK1/GTL2 (14q32) hypomethylation.

2012-02-01
Aberrant methylation at different imprinted loci has been reported for several congenital imprinting disorders, that is, Silver-Russell syndrome (SRS), but the coincidental occurrence of aberrant methylation and uniparental disomy (UPD) has not yet been described. We report on a patient initially diagnosed with SRS carrying a segmental maternal UPD of chromosome 7 [upd(7q)mat]. By further screening the patient's DNA for methylation defects on other chromosomes we identified a hypomethylation of the paternally methylated DLK1/GTL2 locus in 14q32, an epigenotype typically associated with the upd(14)mat phenotype. Detailed clinical analysis confirmed the molecular finding in the patient indicating that the 14q32 epimutation was clinically preponderant. The parallel occurrence of upd(7q)mat and a DLK1/GTL2 hypomethylation in the same patient is a unique finding. Indeed, both disturbances might have occurred coincidentally, but it can also be hypothesized that the upd(7q)mat as the initial genomic mutation represents a trans-acting mutation causing an aberrant methylation in 14q32.
Photons with half-integral spin as q-Fermions
Parthasarathy, R
2016-01-01
The recently discovered 'light (photons) with half-integral spin' is interpreted as q-Fermions proposed by us in 1991, as these q-Fermions satisfy q-deformed anti-commutation relations (pertaining to spin half) and have the property that more than one q-Fermion can occupy a given quantum state. In this article, in view of the recent discovery, we recall the construction of q-Fermions and give the statistical properties of q-Fermion gas, based on our preprint in 1992.

Call centers are strategically and tactically important to many industries, including the healthcare industry. Call centers play a key role in acquiring and retaining customers. The ability to deliver high-quality and timely customer service without much expense is the basis for the proliferation and expansion of call centers. Call centers are unique blends of people and technology, where performance indicates combining appropriate technology tools with sound management practices built on key operational data. While the technology is fascinating, the people working in call centers and the skill of the management team ultimately make a difference to their companies.
Enabling ICH Q10 Implementation--Part 1. Striving for Excellence by Embracing ICH Q8 and ICH Q9.
Calnan, Nuala; O'Donnell, Kevin; Greene, Anne
2013-01-01
This article is the first in a series of articles that will focus on understanding the implementation essentials necessary to deliver operational excellence through a International Conference on Harmonisation of Technical Requirements for Registration of Pharmaceuticals for Human Use (ICH) Q10-based pharmaceutical quality system (PQS). The authors examine why, despite the fact that the ICH Q10 guideline has been with us since 2008, the transformation of the traditional Quality Management Systems QMS in use within the pharmaceutical industry is a work in progress for only a few forward-thinking organisations. Unfortunately, this transformation remains a mere aspiration for the majority of organisations. We explore the apparent lack of progress by the pharmaceutical sector in adopting six sigma and related quality management techniques to ensure the availability of high-quality medicines worldwide. The authors propose that the desired progress can be delivered through two key shifts in our current practices; by embodying the principles of operational excellence in every aspect of our business and by learning how to unlock the scientific and tacit knowledge within our organisations. It has been ten years since The Wall Street Journal revealed the pharmaceutical industry's "little secret" comparing the perceived level of manufacturing expertise in the industry as lagging far behind those of potato-chip and laundry-soap makers. Would you consider the quality and manufacturing strategies in place today in your organisation to be more efficient and scientifically based than those of 2003? If so, what evidence exists for you to draw any conclusion regarding enhanced performance? Do your current practices drive innovation and facilitate continual improvement and if so, how? Ultimately, can you confidently affirm that patient-related risks associated with the product(s) manufactured by your organisation have been reduced due to the quality assurance program now applied
High Q^2 Measurements from HERA
South, David M
2010-01-01
New measurements of neutral and charged current cross sections at large negative four-momentum transfer squared Q^2 have been performed by H1 and ZEUS, using up to the complete HERA II ep data, which was taken with polarised electron and positron beams. The data are compared to predictions of the Standard Model, based on various parton distribution function parameterisations. The polarisation asymmetry of the neutral current interaction is measured as a function of Q^2, as well as the polarisation dependence of the charged current cross section and both are found to be in agreement with the Standard Model expectation. The HERA II cross sections are also combined with previously published HERA I data to obtain the most precise unpolarised measurements.

We study the local description of composite five-branes of codimension two. The formulation is constructed by virtue of the $SL(2,{\\mathbb Z}) \\times SL(2,{\\mathbb Z)}$ monodromy associated with two-torus. Applying the conjugate monodromy transformations to the complex structures of the two-torus, we obtain the field configuration of the defect $(p,q)$ five-branes. This is the composite state of $p$ defect NS5-branes and $q$ exotic $5^2_2$-branes. We also obtain a new hyper-K\\"{a}hler geometry. This is an ALG space, a generalization of an ALF space which asymptotically has a tri-holomorphic two-torus action. This geometry appears in the conjugate configuration of the single defect KK5-brane.
Weyl modules and q-Whittaker functions
Braverman, Alexander
2012-01-01
Let G be a semi-simple simply connected group over complex numbers. In this paper we give a geometric definition of the (dual) Weyl modules over the group G[t] and show that their characters form an eigen-function of the lattice version of the q-Toda integrable integrable system (defined by means of the quantum group version of Kostant-Whittaker reduction due to Etingof and Sevostyanov). All the proofs are algebro-geometric and rely on our previous work which interprets the universal eigen-function of the q-Toda system in terms of rings of functions on the spaces of based quasi-maps from P^1 to the flag variety of G. We discuss in detail the relation between the current work and the works of Cherednik, Ion and Gerasimov-Lebedev-Oblezin.

Full Text Available Abstract Background Only 29 cases of constitutional 9q22 deletions have been published and all have been sporadic. Most associate with Gorlin syndrome or nevoid basal cell carcinoma syndrome (NBCCS, MIM #109400 due to haploinsufficiency of the PTCH1 gene (MIM *601309. Methods and Results We report two mentally retarded female siblings and their cognitively normal father, all carrying a similar 5.3 Mb microdeletion at 9q22.2q22.32, detected by array CGH (244 K. The deletion does not involve the PTCH1 gene, but instead 30 other gene,s including the ROR2 gene (MIM *602337 which causing both brachydactyly type 1 (MIM #113000 and Robinow syndrome (MIM #268310, and the immunologically active SYK gene (MIM *600085. The deletion in the father was de novo and FISH analysis of blood lymphocytes did not suggest mosaicism. All three patients share similar mild dysmorphic features with downslanting palpebral fissures, narrow, high bridged nose with small nares, long, deeply grooved philtrum, ears with broad helix and uplifted lobuli, and small toenails. All have significant dysarthria and suffer from continuous middle ear and upper respiratory infections. The father also has a funnel chest and unilateral hypoplastic kidney but the daughters have no malformations. Conclusions This is the first report of a familial constitutional 9q22 deletion and the first deletion studied by array-CGH which does not involve the PTCH1 gene. The phenotype and penetrance are variable and the deletion found in the cognitively normal normal father poses a challenge in genetic counseling.

In this paper, we define a new nonconforming quadrilateral finite element based on the nonconforming rotated Q1 element by enforcing a constraint on each element, which has only three degrees of freedom. We investigate the consistency, approximation, superclose property, discrete Green's function and superconvergence of this element. Moreover, we propose a new postprocessing technique and apply it to this element. It is proved that the postprocessed discrete solution is superconvergent under a mild assumption on the mesh.

AF1Q, a mixed lineage leukemia gene fusion partner, is identified as a poor prognostic biomarker for pediatric acute myeloid leukemia (AML), adult AML with normal cytogenetic and adult myelodysplastic syndrome. AF1Q is highly regulated during hematopoietic progenitor differentiation and development but its regulatory mechanism has not been defined clearly. In the present study, we used pharmacological and genetic approaches to influence chaperone-mediated autophagy (CMA) and explored the degradation mechanism of AF1Q. Pharmacological inhibitors of lysosomal degradation, such as chloroquine, increased AF1Q levels, whereas activators of CMA, including 6-aminonicotinamide and nutrient starvation, decreased AF1Q levels. AF1Q interacts with HSPA8 and LAMP-2A, which are core components of the CMA machinery. Knockdown of HSPA8 or LAMP-2A increased AF1Q protein levels, whereas overexpression showed the opposite effect. Using an amino acid deletion AF1Q mutation plasmid, we identified that AF1Q had a KFERQ-like motif which was recognized by HSPA8 for CMA-dependent proteolysis. In conclusion, we demonstrate for the first time that AF1Q can be degraded in lysosomes by CMA. - Highlights: • Chaperone-mediated autophagy (CMA) is involved in the degradation of AF1Q. • Macroautophagy does not contribute to the AF1Q degradation. • AF1Q has a KFERQ-like motif that is recognized by CMA core components.

The Q/U Imaging ExperimenT (QUIET) is designed to measure polarization in the cosmic microwave background, targeting the imprint of inflationary gravitational waves at large angular scales({approx}1 Degree-Sign ). Between 2008 October and 2010 December, two independent receiver arrays were deployed sequentially on a 1.4 m side-fed Dragonian telescope. The polarimeters that form the focal planes use a compact design based on high electron mobility transistors (HEMTs) that provides simultaneous measurements of the Stokes parameters Q, U, and I in a single module. The 17-element Q-band polarimeter array, with a central frequency of 43.1 GHz, has the best sensitivity (69 {mu}Ks{sup 1/2}) and the lowest instrumental systematic errors ever achieved in this band, contributing to the tensor-to-scalar ratio at r < 0.1. The 84-element W-band polarimeter array has a sensitivity of 87 {mu}Ks{sup 1/2} at a central frequency of 94.5 GHz. It has the lowest systematic errors to date, contributing at r < 0.01. The two arrays together cover multipoles in the range l {approx} 25-975. These are the largest HEMT-based arrays deployed to date. This article describes the design, calibration, performance, and sources of systematic error of the instrument.
Deletion and substitution analysis of the Escherichia coli TonB Q160 region.
Vakharia-Rao, Hema; Kastead, Kyle A; Savenkova, Marina I; Bulathsinghala, Charles M; Postle, Kathleen
2007-07-01
The active transport of iron siderophores and vitamin B(12) across the outer membrane (OM) of Escherichia coli requires OM transporters and the potential energy of the cytoplasmic membrane (CM) proton gradient and CM proteins TonB, ExbB, and ExbD. A region at the amino terminus of the transporter, called the TonB box, directly interacts with TonB Q160 region residues. R158 and R166 in the TonB Q160 region were proposed to play important roles in cocrystal structures of the TonB carboxy terminus with OM transporters BtuB and FhuA. In contrast to predictions based on the crystal structures, none of the single, double, or triple alanyl substitutions at arginyl residues significantly decreased TonB activity. Even the quadruple R154A R158A R166A R171A mutant TonB still retained 30% of wild-type activity. Up to five residues centered on TonB Q160 could be deleted without inactivating TonB or preventing its association with the OM. TonB mutant proteins with nested deletions of 7, 9, or 11 residues centered on TonB Q160 were inactive and appeared never to have associated with the OM. Because the 7-residue-deletion mutant protein (TonBDelta7, lacking residues S157 to Y163) could still form disulfide-linked dimers when combined with W213C or F202C in the TonB carboxy terminus, the TonBDelta7 deletion did not prevent necessary energy-dependent conformational changes that occur in the CM. Thus, it appeared that initial contact with the OM is made through TonB residues S157 to Y163. It is hypothesized that the TonB Q160 region may be part of a large disordered region required to span the periplasm and contact an OM transporter.

Full Text Available There is increasing evidence that the microcirculation plays an important role in the pathogenesis of cardiovascular diseases. Changes in retinal vascular caliber reflect early microvascular disease and predict incident cardiovascular events. We performed a genome-wide association study to identify genetic variants associated with retinal vascular caliber. We analyzed data from four population-based discovery cohorts with 15,358 unrelated Caucasian individuals, who are members of the Cohort for Heart and Aging Research in Genomic Epidemiology (CHARGE consortium, and replicated findings in four independent Caucasian cohorts (n = 6,652. All participants had retinal photography and retinal arteriolar and venular caliber measured from computer software. In the discovery cohorts, 179 single nucleotide polymorphisms (SNP spread across five loci were significantly associated (p<5.0×10(-8 with retinal venular caliber, but none showed association with arteriolar caliber. Collectively, these five loci explain 1.0%-3.2% of the variation in retinal venular caliber. Four out of these five loci were confirmed in independent replication samples. In the combined analyses, the top SNPs at each locus were: rs2287921 (19q13; p = 1.61×10(-25, within the RASIP1 locus, rs225717 (6q24; p = 1.25×10(-16, adjacent to the VTA1 and NMBR loci, rs10774625 (12q24; p = 2.15×10(-13, in the region of ATXN2,SH2B3 and PTPN11 loci, and rs17421627 (5q14; p = 7.32×10(-16, adjacent to the MEF2C locus. In two independent samples, locus 12q24 was also associated with coronary heart disease and hypertension. Our population-based genome-wide association study demonstrates four novel loci associated with retinal venular caliber, an endophenotype of the microcirculation associated with clinical cardiovascular disease. These data provide further insights into the contribution and biological mechanisms of microcirculatory changes that underlie cardiovascular
Novel features of 3q29 deletion syndrome: Results from the 3q29 registry.
Glassford, Megan R; Rosenfeld, Jill A; Freedman, Alexa A; Zwick, Michael E; Mulle, Jennifer G
2016-04-01
3q29 deletion syndrome is caused by a recurrent, typically de novo heterozygous 1.6 Mb deletion, but because incidence of the deletion is rare (1 in 30,000 births) the phenotype is not well described. To characterize the range of phenotypic manifestations associated with 3q29 deletion syndrome, we have developed an online registry (3q29deletion.org) for ascertainment of study subjects and phenotypic data collection via Internet-based survey instruments. We report here on data collected during the first 18 months of registry operation, from 44 patients. This is the largest cohort of 3q29 deletion carriers ever assembled and surveyed in a systematic way. Our data reveal that 28% of registry participants report neuropsychiatric phenotypes, including anxiety disorder, panic attacks, depression, bipolar disorder, and schizophrenia. Other novel findings include a high prevalence (64%) of feeding problems in infancy and reduced weight at birth for 3q29 deletion carriers (average reduction 13.9 oz (394 g), adjusted for gestational age and sex, P = 6.5e-07). We further report on the frequency of heart defects, autism, recurrent ear infections, gastrointestinal phenotypes, and dental phenotypes, among others. We also report on the expected timing of delayed developmental milestones. This is the most comprehensive description of the 3q29 deletion phenotype to date. These results are clinically actionable toward improving patient care for 3q29 deletion carriers, and can guide the expectations of physicians and parents. These data also demonstrate the value of patient-reported outcomes to reveal the full phenotypic spectrum of rare genomic disorders. © 2016 Wiley Periodicals, Inc.
Science with Q3D mode of SAMURAI
Sekiguchi, Kimiko
2014-09-01
Study of three-nucleon forces (3NFs) is essentially important in clarifying nuclear phenomena. Few-nucleon scattering, e.g. deuteron-proton (dp) elastic scattering, dp breakup reactions, at intermediate energies (E ~ 100 -400 MeV/nucleon) is one attractive probe to investigate the dynamical aspects of 3NFs, such as momentum and/or spin dependences. Direct comparison between the data and the rigorous numerical calculations based on bare nuclear potentials provides information of 3NFs. So far large 3NF effects are theoretically predicted and experimentally confirmed in the cross section minimum for dp scattering at ~ 100 MeV/nucleon. With the aim of clarifying roles of the 3NFs in nuclei the experimental programs with polarized deuteron beams at intermediate energies are in progress at RIBF. At RIBF polarized deuteron beams are available up to 400 MeV/nucleon by using the three cyclotrons, AVF, RRC and SRC. Highly polarized deuteron beams, typical values of which are 80% of the theoretical maximum values, have been obtained at 250 and 300 MeV/nucleon. In order to extract detailed properties of 3NFs high precision data are needed. The Q3D mode of the SAMURAI serves as a high-resolution spectrograph in which the triplet-Q-magnets STQ in conjunction with the SAMURAI dipole magnet are used as analyzer magnets. The momentum resolution of this mode is estimated to be p / δp ~ 3000 . The angular range is covered from 0 - 5 degrees in the laboratory systems. Charge collection of the deuteron beam is performed with the Faraday cup installed downstream of the SAMURAI dipole magnet. This system suits for the study of high momentum transfer region in dp scattering where effects of short range 3NFs are expected to be obtained. As the first measurement with polarized deuteron beams with the SAMURAI Q3D mode dp scattering at very backward angles 160°--180° in the center of mass system is planned.

Economics and Finance: q-Statistical Stylized Features Galore

Full Text Available The Boltzmann–Gibbs (BG entropy and its associated statistical mechanics were generalized, three decades ago, on the basis of the nonadditive entropy S q ( q ∈ R , which recovers the BG entropy in the q → 1 limit. The optimization of S q under appropriate simple constraints straightforwardly yields the so-called q-exponential and q-Gaussian distributions, respectively generalizing the exponential and Gaussian ones, recovered for q = 1 . These generalized functions ubiquitously emerge in complex systems, especially as economic and financial stylized features. These include price returns and volumes distributions, inter-occurrence times, characterization of wealth distributions and associated inequalities, among others. Here, we briefly review the basic concepts of this q-statistical generalization and focus on its rapidly growing applications in economics and finance.
Some Elements of Finite Order in K2Q

Let K2 be the Milnor functor and let Фn(x) ∈ Q[x] be the n-th cyclotomic polynomial. Let Gn(Q) denote a subset consisting of elements of the form {a, Фn(a)}, where a ∈ Q* and {, } denotes the Steinberg symbol in K2Q. J. Browkin proved that Gn (Q) is a subgroup of K2Q if n = 1, 2, 3, 4 or 6 and conjectured that Gn(Q) is not a group for any other values of n. This conjecture was confirmed for n = 2r3s or n = pr, where p ≥ 5 is a prime number such that h(Q(ζ p)) is not divisible by p. Inthis paper we confirm the conjecture for some n, where n is not of the above forms, more precisely, for n = 15, 21, 33, 35, 60 or 105.
Generalization of the possible algebraic basis of q-triplets
Tsallis, Constantino
2017-02-01
The so called q-triplets were conjectured in 2004 [C. Tsallis, Physica A 340, 1 (2004)] and then found in nature in 2005 [L.F. Burlaga, A.F. Vinas, Physica A 356, 375 (2005)]. A relevant further step was achieved in 2005 [C. Tsallis, M. Gell-Mann, Y. Sato, PNAS 102, 15377 (2005)] when the possibility was advanced that they could reflect an entire infinite algebra based on combinations of the self-dual relations q → 2 - q (additive duality) and q → 1/q (multiplicative duality). The entire algebra collapses into the single fixed point q = 1, corresponding to the Boltzmann-Gibbs entropy and statistical mechanics. For q ≠ 1, an infinite set of indices q appears, corresponding in principle to an infinite number of physical properties of a given complex system describable in terms of the so called q-statistics. The basic idea that is put forward is that, for a given universality class of systems, a small number (typically one or two) of independent q indices exist, the infinite others being obtained from these few ones by simply using the relations of the algebra. The q-triplets appear to constitute a few central elements of the algebra. During the last decade, an impressive amount of q-triplets have been exhibited in analytical, computational, experimental and observational results in natural, artificial and social systems. Some of them do satisfy the available algebra constructed solely with the additive and multiplicative dualities, but some others seem to violate it. In the present work we generalize those two dualities with the hope that a wider set of systems can be handled within. The basis of the generalization is given by the selfdual relation q → qa(q) ≡ ((a+2)-aq) / (a-(a-2)q) (a ∈ R). We verify that qa(1) = 1, and that q2(q) = 2 - q and q0(q) = 1/q. To physically motivate this generalization, we briefly review illustrative applications of q-statistics, in order to exhibit possible candidates where the present generalized algebras could be useful.

The location of coenzyme Q10 (Q10) inside the inner mitochondrial membrane is a topic of research aiming at a deeper understanding of the function of the mitochondrial respiratory chain. We investigated the location of Q10 inside model membranes made of 1-palmitoyl-2-oleoyl-phosphatidylethanolamine by means of small-angle synchrotron X-ray diffraction. Q10, which stands for ubiquinone-10 (UQ) or ubihydroquinone-10 (UH), did not remarkably influence the main phase transition temperature, but significantly decreased the lamellar-inverse hexagonal phase transition temperature (T(h)). The effect of UH on T(h) was stronger than the effect of UQ and the effect of liquid Q10 on T(h) was stronger than the effect of crystalline Q10. In the presence of Q10, the lattice parameters of the lamellar phases remained unchanged, whereas the H II lattice parameter was clearly influenced: While UQ had an increasing effect, UH had a decreasing effect. Furthermore, Q10 prevented the formation of cubic phases. The results give new evidence that the headgroup of Q10 is distant from the center of the membrane, which might be important for the function of the mitochondrial respiratory chain.

Full Text Available We establish some inequalities involving Saigo fractional q-integral operator in the theory of quantum calculus by using the two parameters of deformation, q1 and q2, whose special cases are shown to yield corresponding inequalities associated with Riemann-Liouville and Kober fractional q-integral operators, respectively. Furthermore, we also consider their relevance with other related known results.

New localization mechanism and Hodge duality for q -form field
Fu, Chun-E.; Liu, Yu-Xiao; Guo, Heng; Zhang, Sheng-Li
2016-03-01
In this paper, we investigate the problem of localization and the Hodge duality for a q -form field on a p -brane with codimension one. By a general Kaluza-Klein (KK) decomposition without gauge fixing, we obtain two Schrödinger-like equations for two types of KK modes of the bulk q -form field, which determine the localization and mass spectra of these KK modes. It is found that there are two types of zero modes (the 0-level modes): a q -form zero mode and a (q -1 )-form one, which cannot be localized on the brane at the same time. For the n -level KK modes, there are two interacting KK modes, a massive q -form KK mode and a massless (q -1 )-form one. By analyzing gauge invariance of the effective action and choosing a gauge condition, the n -level massive q -form KK mode decouples from the n -level massless (q -1 )-form one. It is also found that the Hodge duality in the bulk naturally becomes two dualities on the brane. The first one is the Hodge duality between a q -form zero mode and a (p -q -1 )-form one, or between a (q -1 )-form zero mode and a (p -q )-form one. The second duality is between two group KK modes: one is an n -level massive q -form KK mode with mass mn and an n -level massless (q -1 )-form mode; another is an n -level (p -q )-form one with the same mass mn and an n -level massless (p -q -1 )-form mode. Because of the dualities, the effective field theories on the brane for the KK modes of the two dual bulk form fields are physically equivalent.
An obstruction for q-deformation of the convolution product
Van Leeuwen, H; van Leeuwen, Hans; Maassen, Hans
1995-01-01
We consider two independent q-Gaussian random variables X and Y and a function f chosen in such a way that f(X) and X have the same distribution. For 0 < q < 1 we find that at least the fourth moments of X + Y and f(X) + Y are different. We conclude that no q-deformed convolution product can exist for functions of independent q-Gaussian random variables.
Proton magnetic resonance spectroscopy in 22q11 deletion syndrome.

Full Text Available OBJECTIVE: People with velo-cardio-facial syndrome or 22q11 deletion syndrome (22q11DS have behavioral, cognitive and psychiatric problems. Approximately 30% of affected individuals develop schizophrenia-like psychosis. Glutamate dysfunction is thought to play a crucial role in schizophrenia. However, it is unknown if and how the glutamate system is altered in 22q11DS. People with 22q11DS are vulnerable for haploinsufficiency of PRODH, a gene that codes for an enzyme converting proline into glutamate. Therefore, it can be hypothesized that glutamatergic abnormalities may be present in 22q11DS. METHOD: We employed proton magnetic resonance spectroscopy ((1H-MRS to quantify glutamate and other neurometabolites in the dorsolateral prefrontal cortex (DLPFC and hippocampus of 22 adults with 22q11DS (22q11DS SCZ+ and without (22q11DS SCZ- schizophrenia and 23 age-matched healthy controls. Also, plasma proline levels were determined in the 22q11DS group. RESULTS: We found significantly increased concentrations of glutamate and myo-inositol in the hippocampal region of 22q11DS SCZ+ compared to 22q11DS SCZ-. There were no significant differences in levels of plasma proline between 22q11DS SCZ+ and 22q11DS SCZ-. There was no relationship between plasma proline and cerebral glutamate in 22q11DS. CONCLUSION: This is the first in vivo(1H-MRS study in 22q11DS. Our results suggest vulnerability of the hippocampus in the psychopathology of 22q11DS SCZ+. Altered hippocampal glutamate and myo-inositol metabolism may partially explain the psychotic symptoms and cognitive impairments seen in this group of patients.
