Spinal muscular atrophy (SMA) is an inherited neuromuscular disease caused by deletion or mutation of SMN1 gene. All SMA patients carry a nearly identical SMN2 gene, which produces low level of SMN protein due to mRNA exon 7 exclusion. Previously, we found that the testis of SMA mice (smn(-/-) SMN2) expresses high level of SMN2 full-length mRNA, indicating a testis-specific mechanism for SMN2 exon 7 inclusion. To elucidate the underlying mechanism, we established primary cultures of testis cells from SMA mice and analyzed them for SMN2 exon 7 splicing. We found that primary testis cells after a 2-hour culture still expressed high level of SMN2 full-length mRNA, but the level decreased after longer cultures. We then compared the protein levels of relevant splicing factors, and found that the level of Tra2-beta 1 also decreased during testis cell culture, correlated with SMN2 full-length mRNA downregulation. In addition, the testis of SMA mice expressed the highest level of Tra2-beta 1 among the many tissues examined. Furthermore, overexpression of Tra2-beta 1, but not ASF/SF2, increased SMN2 minigene exon 7 inclusion in primary testis cells and spinal cord neurons, whereas knockdown of Tra2-beta 1 decreased SMN2 exon 7 inclusion in primary testis cells of SMA mice. Therefore, our results indicate that high expression level of Tra2-beta 1 is responsible for increased SMN2 exon 7 inclusion in the testis of SMA mice. This study also suggests that the expression level of Tra2-beta 1 may be a modifying factor of SMA disease and a potential target for SMA treatment.

Provided is the pixel circuit for active matrix display apparatus and the driving method thereof, which is controlled by digital signal. The pre-charge pixel voltage is controlled and discharged by controlling the resistor and transistors, so that the desired grey scale is generated. The pixel circuit includes: a first switch, a second switch, a third switch, an energy storage device and resistor. By controlling the third switch, the first end of the energy storage device is charged to the voltage of the second source. The first switch and the second switch are controlled to switch on, so that the first end of the energy storage device discharging to the first source. The second switch switches off when the first end of the energy storage device reaches the desired pixel voltage.

We have studied hydrogen-atom tunneling in the cis-to-trans conformational change of some carboxylic acid monomers and formic acid (FA) complexes and dimers at the MP2(full) and CCSD(T) levels of theory within the Wentzel-Kramers-Brillouin approximation. The barrier for the minimum energy path, where the OH bond length and the COH bending angle are optimized, is found to be a good approximation for providing the highest barrier transparency. The matrix effect on the transmission coefficients of cis-FA monomer, trans-cis FA dimer (tc1), and cis-acetic acid monomer are modeled by the polarizable continuum model (PCM) at the MP2(full) level of theory in different environments. For the cis-FA monomer and trans-cis FA dimer (tc1), the calculated transmission coefficients agree with the experimental lifetimes observed in noble-gas solids. However, this method cannot reproduce the experimental results obtained for cis-acetic acid. Moreover, the long lifetime of cis-FA and cis-acetic acid in the N-2 environment cannot be reproduced either, which is most probably due to specific interactions that are not included in the PCM. The calculation for cis-HCOOD shows a strong decrease of the barrier transparency compared to that for cis-HCOOH, which is consistent with the experiments. In general, good agreement is observed between the calculated barrier transparency (including PCM) and experimental tunneling rate. However, some exceptions are found, which shows that additional factors influence the tunneling rate.

Proton-bound rare-gas dimer (RgHRg)(+), in which Rg represents a rare-gas atom, serves as a prototypical system for proton solvation by inert-gas atoms. Until now, only centrosymmetric species with Rg = Ar, Kr, or Xe have been identified with infrared spectra. We employed electron bombardment during deposition of a mixture of Xe (or Kr) in p-H-2 at 3.2 K to prepare (RgHRg)(+). Lines at 847.0 and 972.1 cm(-1) are assigned as the Rg-H-Rg antisymmetric stretching (nu(3)) mode and its combination with the RgHRg symmetric stretching (nu(1) + nu(3)) mode of (XeHXe)(+) in solid p-H-2, respectively. Lines at 871.1 and 974.0 cm(-1) are assigned as the nu(3) and nu(1) + nu(3) modes of (KrHKr)(+) in solid p-H-2, respectively. Slightly shifted and broadened lines were observed for these species in solid n-H-2. These results agree satisfactorily with reported experimental values of (XeHXe)(+) and (KrHKr)(+) in solid Xe, Kr, and Ar, and with the quantum-chemically predicted anharmonic vibrational wavenumbers of these species in the gaseous phase; the significant spectral shifts in various matrixes are rationalized with the proton affinities of the hosts. When a mixture of Xe and Kr in p-H-2 was used, an additional broad feature at 1284 cm(-1) was observed and assigned as the nu(3) mode of (KrHXe)(+) in solid p-H-2. This line shifted to 1280 cm(-1) in solid n-H-2 and the corresponding line of (KrDXe)(+) was observed at 954 cm(-1) in n-D-2. The observations of these lines are new; the wavenumbers significantly blue shifted from those of the centrosymmetric (RgHRg)(+) agree with the quantum-chemically predicted anharmonic vibrational wavenumbers of 1279 cm(-1) for (KrHXe)(+) and 916 cm(-1) for (KrDXe)(+). Analysis of the computational results shows that electronic correlation effects play a much greater role for the asymmetric than for the symmetric species. An interpretation for this is provided.

A method for treating wastewater containing TMAH and ammonium nitrogen includes the steps of (a) introducing a first solution which contains ammonium nitrogen but no TMAH into a single reactor with microorganisms comprising nitrifying bacteria and anammox bacteria, and denitrifying the first solution by the microorganisms under a dissolved oxygen concentration ranging from 0.1-0.5 mg/L and a pH value of 7-8; (b) when the denitrification efficiency reaches a steady state, introducing a second solution which contains ammonium nitrogen and TMAH and has a concentration of TMAH lower than 60 mg/L into the reactor; and (c) gradually increasing the concentration of TMAH in the solution to be added into the reactor for several times whenever the denitrification efficiency reaches a steady state. Accordingly, the inhibition of TMAH to the anammox bacteria can be significantly decreased, and both TMAH and the ammonium nitrogen can be treated simultaneously.

Mechanically encoded single-photon sources: Stress-controlled excitonic fine structures of droplet epitaxial quantum dots

We present numerical investigations based on the Luttinger-Kohn four-band k . p theory and, accordingly, establish a quantitatively valid model of the excitonic fine structures of droplet epitaxial GaAs/AlGaAs quantum dots under uniaxial stress control. In the formalisms, stressing a photoexcited quantum dot is equivalent creating a pseudomagnetic field that is directly coupled to the pseudospin of the exciton doublet and tunable to tailor the polarized fine structure of exciton. The latter feature is associated with the valence-band mixing of exciton, which is especially sensitive to external stress in inherently unstrained droplet epitaxial GaAs/AlGaAs quantum dots and allows us to mechanically design and prepare any desired exciton states of QD photon sources prior to the photon generation.

本發明實施例提供一種包括第一延遲迴路、第二延遲迴路以及震盪信號控制電路的數位控制震盪器。震盪信號控制電路用以接收第一延遲迴路輸出的第一延遲信號，並根據接收第一延遲信號的次數決定將第一延遲信號輸出至第一或第二延遲迴路的輸入端。當震盪信號控制電路將第一延遲信號輸入至第二延遲迴路後，第二延遲迴路輸出第二延遲信號至數位控制震盪器的輸出端。透過減少延遲單元的數量，可大幅減少第二延遲信號所經過的閘延遲，並可大幅降低電路設計複雜度與電路面積，故此數位控制震盪器具有較低的成本與較高的頻寬。
