Abstract: Vanillin dehydrogenases are important enzymes involved in the conversion of lignin-derived aromatic aldehydes such as vanillin and p-hydroxybenzaldehyde into its acid form. In a previous study we identified the first fungal vanillin dehydrogenase (VdhA) from the filamentous fungus Aspergillus niger. In this study we heterologous produced VdhA in a bioreactor to obtain sufficient enzyme for a more details analysis of its biochemical properties. This demonstrated that VdhA has a high optimal temperature (50 °C), neutral optimum pH and a broad substrate specificity for aromatic aldehydes. Deletion of vdhA in A. niger resulted in reduced growth on several aromatic aldehydes, largely collating with the in vitro substrate specificity of the enzyme. In addition, we demonstrated that VdhA can convert multiple aromatic aldehydes present in depolymerized lignin, indicating that VdhA can be applied in industrial conversion of lignin fractions to either simplify the composition of the fraction or to reduce the aldehydes that can undergo undesired repolymerization reactions within the mixture.

2. CreA-mediated repression of gene expression occurs at low monosaccharide levels during fungal plant biomass conversion in a time and substrate dependent manner

Abstract: Carbon catabolite repression enables fungi to utilize the most favourable carbon source in the environment, and is mediated by a key regulator, CreA, in most fungi. CreA-mediated regulation has mainly been studied at high monosaccharide concentrations, an uncommon situation in most natural biotopes. In nature, many fungi rely on plant biomass as their major carbon source by producing enzymes to degrade plant cell wall polysaccharides into metabolizable sugars. To determine the role of CreA when fungi grow in more natural conditions and in particular with respect to degradation and conversion of plant cell walls, we compared transcriptomes of a creA deletion and reference strain of the ascomycete Aspergillus niger during growth on sugar beet pulp and wheat bran. Transcriptomics, extracellular sugar concentrations and growth profiling of A. niger on a variety of carbon sources, revealed that also under conditions with low concentrations of free monosaccharides, CreA has a major effect on gene expression in a strong time and substrate composition dependent manner. In addition, we compared the CreA regulon from five fungi during their growth on crude plant biomass or cellulose. It showed that CreA commonly regulated genes related to carbon metabolism, sugar transport and plant cell wall degrading enzymes across different species. We therefore conclude that CreA has a crucial role for fungi also in adapting to low sugar concentrations as occurring in their natural biotopes, which is supported by the presence of CreA orthologs in nearly all fungi.

Abstract: Background: Schizophrenia is associated with an increased risk of sudden cardiac death, traditionally attributed to prolongedQTc interval and increasedprevalence of cardiovascular risk factors. However, defective ion channels implicated in both schizophrenia and Brugada Syndrome (BrS)may be associated with an increased risk of cardiac arrhythmias. Moreover, these cardiac arrhythmias can be provoked by various drugs, including psychotropic drugs. Objective: To assess the prevalence of the occurrence of ECG suspicious for BrS (suspect BrS-ECG) and the prevalence of BrS in patients with recent onset schizophrenia spectrum disorders (SSD). Methods: In this case-control study, ECGs of 388 patients with recent onset SSD admitted between 2006 and 2015 and 844 healthy controls weremade. All persons who had a suspect BrS-ECG were offered an ajmaline provocation test to diagnose or exclude BrS. Data on possible confounders were ascertained. Patients with and without suspect BrS-ECG were compared regarding clinical and ECG variables. Results: Suspect BrS-ECG was found in 33 patients (8.5%) and 13 healthy controls (1.5%),with an adjustedOdds Ratio of 3.5 (p b 0.0001). This findingwas not explained by potential confounders such as gender, age, ethnicity, cannabis use, cardiovascular risk factors, medication use or serum electrolytes. BrSwas confirmed in three patients and one control. Conclusion: A considerable subset of patientswith recent onset SSD have suspect BrS-ECG, extending earlier findings in patients with chronic schizophrenia. Screening for BrS in schizophrenia could be relevant both to prevent sudden cardiac death and to identify a subgroup of patients with possible ion-channel dysfunctioning.

Abstract: Many women would like their mascara beauty benefits to be available all day, every day. One way to address this desire is through a semi-permanent mascara technology that provides full mascara benefits of long, dark beautiful lashes for multiple days. To date, products promising multi-day benefits have acted more as either 'lash dyes', providing a lash darkening benefit but failing to provide fullness and length, or waterproof mascaras that do not maintain the initial beauty look over multiple days. Here, a formulation approach is described for a mascara product that is designed to be abrasion resistant, flexible and insoluble in soap and water so that the initial beauty look is maintained for multiple days. The new semi-permanent formula technology uses rosinate polymers that have a superior combination of flexibility, abrasion resistance and water and surfactant resistance. Based on principles used by the paint industry for creating durable films, the levels of the polymers and other non-volatile ingredients are balanced such that the product forms a continuous polymer film on the eyelash. Cryo-SEM is used to demonstrate that the new semi-permanent formula technology forms a film different from those formed by current mascara products. A stretch test and rub test are used to demonstrate that the new semi-permanent formula technology has superior flexibility and abrasion resistance to current mascara products. Finally, a multi-day consumer study with daily imaging of the eyes is used to demonstrate the superior wear performance of the new semi-permanent formula technology in actual usage.

Abstract: We have searched for anomalous Z → γγγ events with the L3 detector at LEP. No significant deviations from the expected QED e+e− → γγγ events are observed. The branching ratio upper limit for a compoite Z decaying directly into three photons is found to be 1.0 × 10−5 at 95% C.L. The branching ratio upper limits for the process Z → γX, X → γγ are in the range of 0.4 to 1.3 × 10−5, depending on the mass and width of the scalar particle X. In the context of a model with magnetic monopoles coupling to the Z, we find BR(Z → γγγ) < 0.8 × 10−5 at 95% C.L.; this results in a lower mass limit of 510 GeV for a magnetic monopole., Facultad de Ciencias Exactas

Abstract: We have measured the branching fractions for the hadronic τ decays, τ→π/Knπ°v (0 ≤ n ≤ 3), with the L3 detector at LEP. Multiphoton final states are analyzed using the fine-grained, high-resolution electromagnetic calorimeter. The decay channels are identified using a neural network method. The results are: BR(τ→π/Kv) = (11.82 ± 0.26 ± 0.43)%, BR (τ→π/Kπ°v) = (25.05 ± 0.35 ± 0.50)%, BR(τ→π/ K2π°v) = (8.88 ± 0.37 ± 0.42)%, BR(τ→π/K3π°v) = (1.70 ± 0.24 ± 0.38)%, where the first error quoted is statistical, the second systematic., Facultad de Ciencias Exactas

Abstract: We have observed B0-B0 mixing in Z0→bb decays using hadronic events containing dileptons. The data sample corresponds to 118 200 hadron events at √s≈Mz. From a fit to the dilepton p and p⊥ spectra, we determine the mixing parameter to be χB=0.178-0.040 +0.049. © 1990.

Abstract: We have measured the forward-backward asymmetry in Z 0 → b b decays using hadronic events containing muons and electrons. The data sample corresponds to 118 200 hadronic events at √s≈Mz. From a fit to the single and dilepton p and P⊥ spectra, we determine A b b =0.130 −0.042 +0.044 including the correction for B 0 − B 0 mixing.

Abstract: Whatever the field, major change implies as much as deep transformation of thinking i.e to put in network new skills in particular, those made available by the availability of new technologies. In this context, only one individual cannot join together all necessary skills. It becomes clear that the goal of space valorization cannot be considered without relational investment between the partners and their accumulated background. The local empowerment concerns a collective phenomenon of acquisition and development of skills rests on an learning way appropriate to the potential of the territory to form or promote. The local mediation sets for objective the creation of relations between pre-existent skills and their transfer between the actors, individuals or groups, private or public. But the capacity of the territory to solve these problems will depend closely on the richness of the network and co-operations which it shelters or it will suggest.

Abstract: The L3 experiment is one of the six large detectors designed for the new generation of electron-positron accelerators. It is the only detector that concentrates its efforts on limited goals of measuring electrons, muons and photons. By not attempting to identify hadrons, L3 has been able to provide an order of magnitude better resolution for electrons, muons and photons. Vertices and hadron jets are also studied. The construction of L3 has involved much state of the art technology in new principles of vertex detection and in new crystals for large scale electromagnetic shower detection and ultraprecise muon detection. This paper presents a summary of the construction of L3.

Abstract: We have searched for charged and neutral leptons. We exclude stable Dirac neutrinos below 42.8 GeV and stable Majorana neutrinos below 34.8 GeV. From a search for unstable neutrinos we exclude masses below 46.4 GeV (Dirac) and below 45.1 GeV (Majorana). We exclude all masses of sequential charged and neutral leptons, except if both masses are larger than 42.8 GeV (for stable Dirac neutrinos). All mass limits correspond to 95% CL.

Abstract: We have measured the partial widths of the Z 0 into lepton pairs, and the forward-backward charge asymmetry for the process e + e − → μ + μ − using the L3 detector at LEP. We obtain an average Γ ll of 83.0±2.1±1.1 MeV.From this result and the asymmetry measurement, we extract the values of the vector and axial vector couplings of the Z 0 to leptons: g rmv =−0.066 −0.027 +0.046 and g rmA = −0.495 −0.007 +0.007 .

Abstract: Within a context of evolution and the rapid integration of digitization in university publishing, the fields of the humanities and social sciences, and in particular those of textbooks, do not appear to have found a satisfactory distribution model. In this article, we shall attempt to explain in what measure this sector is different from other areas of university publishing and what hypotheses can be put forward for its future development. Having suggested a carving up of the university publishing market, we would like to place it briefly in an international context. On the basis of this finding, we will present the hypothesis of aggregation: why this should be required, why it does not yet exist and which needs it will respond to. We shall conclude by summarizing these points which we believe are key to the development of a digital university offer in France for the humanities and social sciences.

Abstract: The design and implementation of the magnetic field measuring system of the L3 detector is described. The system features 992 permanently installed magnetoresistors which serve the mapping of the nominally 0.5 T field of the L3 magnet over its entire 1200 m3 volume. It enables the reconstruction of the magnetic field to an accuracy of better than 0.4%. To allow the magnetoresistors to be used over an extended range of ambient temperatures, a passive temperature compensation scheme has been devised. An internally calibrated read-out system under microprocessor control facilities easy access to the magnetic field data. Furthermore, the mechanical design of the system, its calibration and the field reconstruction procedures are described.

Abstract: We have searched for the neutral Higgs boson produced in decays of the Z0 through the process e+e-→Z0→H0Z0 *. The data sample analyzed corresponds to 111 200 hadronic decays of the Z0. Combining the results of this analysis with previous L3 results we exclude a minimal standard model Higgs boson in the mass range 0

Abstract: We present a study of energy-energy correlations based on 83 000 hadronic Z0 decays. From this data we determine the strong coupling constant αs to second order QCD: αs(91.2 GeV)=0.121±0.004(exp.)±0.002(hadr.)-0.006 + 0.009(scale)±0.006(theor.) from the energy-energy correlation and αs(91.2 GeV)=0.115±0.004(exp.)-0.004 +0.007(hadr.) -0.000 +0.002(scale)- 0.005 +0.003 (theor.) from its asymmetry using a renormalization scale μ1=0.1 s. The first error (exp.) is the systematic experimental uncertainly, the statistical error is negligible. The other errors are due to hadronization (hadr.), renormalization scale (scale) uncertainties, and differences between the calculated second order corrections (theor.). © 1991.

Abstract: We have measured the cross-section of the reaction e + e − → γγ at center of mass energies around the Z 0 mass. The results are in good agreement with QED predictions. For the QED cutoff parameters the limit of Λ + > 103 GeV and Λ − 118 GeV are found. For the decays Z 0 → γ ,Z 0 → π 0 γ , Z 0 → γγγ we find upper limits of 2.9 × 10 −4 ,2.9×10 −4 ,4.1×10 −4 and 1.2×10 −4 , respectively. All limits are at 95% CL.

Abstract: We present the results from a search for the light neutral scalar Higgs boson h° and the pseudoscalar Higgs boson A° of the minimal super-symmetric standard model. The analysis is based on a data sample corresponding to 71 000 hadronic Z° decays recorded with the L3 detector at LEP. No evidence for the existence of the neutral Higgs bosons h° and A° has been found. The region of h° and A° masses up to 41.5 GeV is excluded at 95% confidence level.

Abstract: We have measured the properties of Z0 → b b decays using a sample of 944 inclusive muon events, corresponding to 18 000 hadron events obtained with the L3 detector at LEP. We measured the partial decay width of the Z0 into b b , Γ b b =353±48 MeV , and we determined the vector coupling of the Z0 to the b quark; grmv2(b)=0.095±0.047. We measured the forward-backward charge asymmetry in e+e− → b b events at √s≈Mv, and obtained A b b =13.3±9.9% .

Abstract: If simplified, every information retrieval problem can be solved when the information need implied by its expression has been identified. We are interested in the criteria used in realising a good information retrieval problem expression. We have listed these criteria through some principles and maxims which first characterized the communication between two persons are applied. We choose to use the gricean maxims because they are the most favoured for this type of situation. Secondly, we have tried to identify some others principles that can be used to realise a good information retrieval problem expression. The principles by Grice can not resolve all forms of error associated with this particular form of communication. In our work, we defined three other principles namely: adhesion principle, reformulation principle, memorization principle. We give some examples of situations where the principles we have formulated are not applicable and the consequences. We present the possible applications of our new model: MIRABEL, which can help in the description of information retrieval problem from. It also compels its user to use essential good expression principle implicitly.

Abstract: We have searched for the excited electron neutrino produced from Z 0 decays in the channel e + e − →νν ∗ using the L3 detector at LEP. The decays ν ∗ →eW and ν ∗ →νγ have been investigated. We have determined an upper limit on the Zνν ∗ coupling as a function of m ν ∗ up to the Z 0 mass.

Abstract: We have measured the partial widths for the three reactions e + e − → Z 0 → e + e − , μ + μ − , τ + τ − . The results are Γ ee = 84.3±1.3 MeV, √ Γ ee Γ μμ =83.9±1.4 MeV, and √ Γ ee Γ ττ =83.9±1.4 MeV, where the errors are statistical. The systematic errors are estimated to be 1.0 MeV, 0.9 MeV, and 1.4 MeV, respectively. We perform a simultaneous fit to the cross sections for the e + e − →e + e − , μ + μ − , and τ + τ − data, the differential cross section as a function of polar angle for the electron data, and the forward- backward asymmetry for the muon data. We obtain the leptonic partial with Γ ll =84.0±0.9 (stat.) MeV. The systematic error is estimated to be 0.8 MeV. Also, we obtain the axial-vector and vector weak coupling constants of charged leptons, g A =−0.500±0.003 and g ν =−0.064 −0.013 +0.017 .

Abstract: We report the results of first physics runs of the L3 detector at LEP. Based on 2538 hadron events, we determined the mass m z 0 and the width Γ z 0 of the intermediate vector boson Z 0 to be m z 0 =91.132±0.057 GeV (not including the 46 MeV LEP machine energy uncertainty) and Γ z 0 =2.588±0.137 GeV. We also determined Γ invisible =0.567±0.080 GeV, corresponding to 3.42±0.48 number of neutrino flavors. We also measured the muon pair cross section and determined the branching ratio Γ μμ = Γ h =0.056±0.006. The partial width of Z 0 →e + e − is Γ ee =88±9±7 MeV.

Abstract: A search for the neutral Higgs boson, using the processes Z 0 → H 0 e + e − , Z 0 → H 0 μ + μ − , Z 0 → H 0 τ + τ − , Z 0 → H 0 v v and Z 0 → H 0 q q , is performed on data collected by the ALEPH detector corresponding to about 11 550 events of Z0 → hadrons. Combining all these processes, the mass range excluded is 32 MeV−15 GeV at 95% CL and 40 MeV−12 GeV at 99% CL. The result from this experiment is unambiguous in the context of the standard model.
