description: L’agroécologie est une notion polysémique qui indique des pratiques, des recherches et un mouvement. De plus, en France, la notion d’agroécologie a été associée à une transition pour indiquer le passage vers des nouvelles pratiques et systèmes. La mise en place de cette transition interroge les innovations mécaniques et le rôle de la motorisation, qui ont contribué aux multiples évolutions de l’agriculture. Par conséquent, les acteurs de l’agro-machinisme et des agroéquipements sont attendus pour apporter des innovations qui puissent opérationnaliser, avec d’autres leviers, la transition agroécologique. Dans ce cadre, la notion d’agroécologie nécessite d’être définie au-delà des fondements agronomiques et clarifiée pour les constructeurs d’agroéquipements. Dans cet article nous présentons une démarche exploratoire de co-construction d’une définition partagée. Afin de clarifier le périmètre de cette notion, nous avons conçu un jeu de cartes reliant les objectifs de l’agroécologie et les objectifs en développement durable des agroéquipementiers en nous basant sur le tripode économie-environnement-société. Ce document présente un atelier participatif selon le principe des jeux sérieux, construit autour de la question : Quels liens de correspondance existent entre agroécologie et développement durable dans le cadre d’une approche globale incluant les industries de l’agroéquipement ? Nous présentons ici la démarche et un exemple de résultats, afin de discuter les limites perçues et des perspectives d’amélioration.

description: Context. Radio relics in galaxy clusters are known to be good laboratories for verification of the applicability of the diffusive shock acceleration (DSA) model in its canonical version. The need for such verification stems from the inconsistencies in the shock properties resulting from radio observations compared to X-ray observations. Aims. In this article we aim to explore how the presence of a second shock in the vicinity of a relic modifies the spectrum of accelerated electrons and decipher which of the involved parameters can have a significant impact on their shape. Methods. We analytically studied DSA of cosmic rays in two stationary shocks aiming to investigate the change of the distribution function. The latter eventually leads to spectrum slope deviations visible in different observations and simulations that do not appear to be explained by the case wherein cosmic rays interact with a single shock wave. Results. We obtain a complex distribution function $f(x,p)$ depending on many parameters (distance between two shocks, compression ratios, spatial diffusion coefficients, injection value, etc.). This function reveals modifications that occur because of the coupled acceleration in both shocks. Apparently, deviations in the particle spectrum from the pure power law depend on a few parameters such as $Q_{1}/Q_{2} $, $κ_{1}/κ_{2} $, $r_{1}/r_{2} $, and $L$. Although we do not verify this idea by taking a particular cluster as an example, we demonstrate a potential cause of spectral disturbances in radio relics. In general terms, our findings appear to correlate with results from the literature when the distance between the shocks is of the order of the width of a radio relic and $κ_{1}/κ_{2} \propto 3$.

description: We searched for 21-cm absorption associated with the z_abs = 1.3647 absorption system toward PKS 0237-233 using the GMRT. A high quality UVES spectrum shows that C I and C I* are detected at this redshift together with C II*, Mg I, Mg II, Si II, Al II, Fe II and Mn II. The complex profiles, spread over ~300 km/s, are fitted with 21 Voigt profile components. None of these components are detected in 21-cm absorption down to a detection limit of τ(3σ)\le 3x10^{-3} (or N(HI)/T_S <10^{17} cm ^-2 K^-1). We derive log N(HI)<19.30$\pm$0.30 using the Lyman alpha absorption line detected in the IUE spectrum of the quasar. Mg II, Si II and Al II column densities are consistent with near solar metallicity and we measure [O/H]>-0.33. Using photoionization models constrained by the fine-structure excitations of C I and C II, and the 21-cm optical depth, we show that the C I absorption arises predominantly either in WIM or WNM in ionization and thermal equilibrium with the meta-galactic UV background dominated by QSOs and star forming galaxies. The estimated thermal pressure of the gas is of the same order of magnitude over different velocity ranges through the absorption profile (2.6\le log [P/k cm^{-3} K]\le 4.0). The gas-phase metallicity corrected for ionization is Z>0.5 Z_\odot with a signature of Fe co-production elements being under abundant compared to α-process elements by ~0.5 dex. At z>1.9, C I absorption is usually associated with H_2 absorption arising from cold gas in DLAs. This system and the z=2.139 toward Tol 1037-270 are the only two systems known which show that C I absorption can also be detected in warm gas provided the metallicity is high enough. Interestingly, both the systems are part of unusual concentrations of absorption lines.

An investigation of the activity and stability of caldocellum saccharolyticum β-glucosidase
Creators: name: Stevenson, Andrew D.
Publisher: name: University of British Columbia
Year: 2009

description: The activity and stability of the thermostable Caldocellum saccharolyticum β-glucosidase has been investigated and the properties compared to the β-glucosidase derived from the mesophile Agrobacterium faecalis, with which there exists a 50% sequence similarity. Previous work on the Agrobacterium β-glucosidase has indicated that the enzyme operates via a two-step mechanism, consisting of initial cleavage of the glycosidic bond with formation of a covalent glycosyl-enzyme intermediate (glycosylation), followed by hydrolysis of this intermediate to yield free enzyme and glycose (deglycosylation). The high degree of sequence similarity between the Agrobacterium and Caldocellum enzymes, combined with the kinetic data determined herein, strongly suggests that the Caldocellum β-glucosidase operates through the same mechanism. Values of k[sub cat] and K[sub M] were determined for enzymic hydrolysis of twelve substituted phenyl-β-D-glucopyranosides with leaving group pK[sub a]'s ranging from 5.49 to 10.32. Values of log k[sub cat] shown no significant dependence upon leaving group pK[sub a], indicative of rate-limiting deglycosylation with all substrates except those with very poor leaving groups (pK[sub a] > 9.5). Substrates with poor leaving groups show a β1[sub g] of -0.2 suggesting very little cleavage of the glycosidic bond in the glycosylation transtion state. This contrasts with the Agrobacterium (β-glucosidase which shows a β1[sub g] of -0.7, indicating significant cleavage of the glycosidic bond in the transition state. There exists a good correlation between the Agrobacterium and Caldocellum β-glucosidase log k[sub cat]/K[sub M] values for these substrates, indicative of similarities in the enzymic binding site. Values of k[sub cat] and K[sub M] were determined for enzymic hydrolysis of six 4-nitrophenyl glycopyranosides. A reasonable correlation of the log k[sub cat]/K[sub M] glycoside hydrolysis exists between the two enzymes, further indicating a similar binding site structure. An activation energy barrier of 7 kcal mol⁻¹ was determined for the Caldocellum enzyme, this comparing reasonably well with a value of 9 kcal mol⁻¹ for the Agrobacterium (β-glucosidase, again indicating a similar conformation of the two enzymes.The Caldocellum β-glucosidase is significantly more stable to both thermal and chemical denaturation than the Agrobacterium enzyme, by at least 3 kcal mol⁻¹. The stability of either enzyme was found to increase when trapped as the 2-fluoroglycosyl-enzyme intermediate, this increase in stability relating to the strength of the interactions with the substrate; again this increase in stability was at least 3 kcal mol⁻¹. The Caldocellum enzyme's higher content of hydrophobic amino acids and a lower net charge, apparent from a comparison of the sequence the two enzymes, are believed to be responsible for its greater stability.
Formation of bright solitons and soliton trains in a fermion-fermion mixture by modulational instability

description: We employ a time-dependent mean-field-hydrodynamic model to study the generation of bright solitons in a degenerate fermion-fermion mixture in a cigar-shaped geometry using variational and numerical methods. Due to a strong Pauli-blocking repulsion among identical spin-polarized fermions at short distances there cannot be bright solitons for repulsive interspecies interactions. Employing a linear stability analysis we demonstrate the formation of stable solitons due to modulational instability of a constant-amplitude solution of the model equations for a sufficiently attractive interspecies interaction. We perform a numerical stability analysis of these solitons and also demonstrate the formation of soliton trains by jumping the effective interspecies interaction from repulsive to attractive. These fermionic solitons can be formed and studied in laboratory with present technology.

description: We use quantum kinetic theory to calculate the thermoelectric transport properties of the 2D single band Fermi-Hubbard model in the weak coupling limit. For generic filling, we find that the high-temperature limiting behaviors of the electrical ($\sim T$) and thermal ($\sim T^2$) resistivities persist down to temperatures of order the hopping matrix element $T\sim t$, almost an order of magnitude below the bandwidth. At half filling, perfect nesting leads to anomalous low temperature scattering and nearly $T$-linear electrical resistivity at all temperatures. We hypothesize that the $T$-linear resistivity observed in recent cold atom experiments is continuously connected to this weak coupling physics and suggest avenues for experimental verification. We find a number of other novel thermoelectric results, such as a low-temperature Wiedemann-Franz law with Lorenz coefficient $5π^2/36$.

description: It has been suggested that neural systems across several scales of organization show optimal component placement, in which any spatial rearrangement of the components would lead to an increase of total wiring. Using extensive connectivity datasets for diverse neural networks combined with spatial coordinates for network nodes, we applied an optimization algorithm to the network layouts, in order to search for wire-saving component rearrangements. We found that optimized component rearrangements could substantially reduce total wiring length in all tested neural networks. Specifically, total wiring among 95 primate (Macaque) cortical areas could be decreased by 32%, and wiring of neuronal networks in the nematode Caenorhabditis elegans could be reduced by 48% on the global level, and by 49% for neurons within frontal ganglia. Wiring length reductions were possible due to the existence of long-distance projections in neural networks. We explored the role of these projections by comparing the original networks with minimally rewired networks of the same size, which possessed only the shortest possible connections. In the minimally rewired networks, the number of processing steps along the shortest paths between components was significantly increased compared to the original networks. Additional benchmark comparisons also indicated that neural networks are more similar to network layouts that minimize the length of processing paths, rather than wiring length. These findings suggest that neural systems are not exclusively optimized for minimal global wiring, but for a variety of factors including the minimization of processing steps.

description: By partially substituting the tri-valence element La with di-valence element Sr in $LaOFeAs$, we introduced holes into the system. For the first time, we successfully synthesized the hole doped new superconductors $(La_{1-x}Sr_x)OFeAs$. The maximum superconducting transition temperature at about 25 K was observed at a doping level of x = 0.13. It is evidenced by Hall effect measurements that the conduction in this type of material is dominated by hole-like charge carriers, rather than electron-like ones. Together with the data of the electron doped system $La(O_{1-x}F_x)FeAs$, a generic phase diagram is depicted and is revealed to be similar to that of the cuprate superconductors.

description: We show that the stochastic Schrödinger equation (SSE) provides an ideal way to simulate the quantum mechanical spin dynamics of radical pairs. Electron spin relaxation effects arising from fluctuations in the spin Hamiltonian are straightforward to include in this approach, and their treatment can be combined with a highly efficient stochastic evaluation of the trace over nuclear spin states that is required to compute experimental observables. These features are illustrated in example applications to a flavin-tryptophan radical pair of interest in avian magnetoreception, and to a problem involving spin-selective radical pair recombination along a molecular wire. In the first of these examples, the SSE is shown to be both more efficient and more widely applicable than a recent stochastic implementation of the Lindblad equation, which only provides a valid treatment of relaxation in the extreme-narrowing limit. In the second, the exact SSE results are used to assess the accuracy of a recently-proposed combination of Nakajima-Zwanzig theory for the spin relaxation and Schulten-Wolynes theory for the spin dynamics, which is applicable to radical pairs with many more nuclear spins. An appendix analyses the efficiency of trace sampling in some detail, highlighting the particular advantages of sampling with SU(N) coherent states.

Η αμπελογραφική αξιολόγηση έγινε σύμφωνα με ορισμένους κωδικούς περιγραφής του Διεθνούς Οργανισμού Αμπέλου και Οίνου (List of 48 descriptors to use in GRAPEGEN06). Tα χαρακτηριστικά που μελετήθηκαν σε κάθε ποικιλία ξεχωριστά είναι τα εξής: νεαρή κορυφή, νέα φύλλα, αναπτυγμένα φύλλα, χαρακτηριστικά σταφυλιού, χαρακτηριστικά ράγας, σάκχαρα και οξύτητα. Επιπλέον , μετρήθηκε το βάρος των ραγών, η περιεκτικότητα των φλοιών σε ανθοκυάνες καθώς και τα φαινολικά συστατικά φλοιών και γιγάρτων. Τέλος ακολούθησε η γενετική ανάλυση 16 ερυθρών και 36 λευκών ποικιλιών με μοριακούς δείκτες και πιο συγκεκριμένα, χρησιμοποιήθηκε η μέθοδος των Μικροδορυφόρων (microsatellites) ή Aπλές Επαναλαμβανόμενες Αλληλουχίες (SSR). Η απομόνωση του DNA έγινε με την εφαρμογή του πρωτοκόλλου NucleoSpinⓇPlant II, στην συνέχεια προστέθηκαν 10 ζεύγη εκκινητών και πραγματοποιήθηκε η αλυσιδωτή αντίδραση πολυμεράσης (PCR). Χρησιμοποιώντας τα δεδομένα της ανάλυσης δημιουργήθηκε ένα κυκλικό δενδρόγραμμα το οποίο απεικονίζει τη γενετική συγγένεια των ποικιλιών.
description: During the vegetative period 2015, 25 red and 34 white Vitis vinifera L. varieties which are maintained in the experimental vineyard of the Aristotle University of Thessaloniki were studied in terms of their ampelographic characteristics. The ampelographic study was done according to the OIV Descriptor List (Office International de la Vigne et du Vin). The characteristics studied in each variety separately are the young shoot, young leaves, mature leaves, characteristics of the bunch, characteristics of the berry, sugar content and total acidity. Furthermore, the berry weight, the concentration of anthocyanins, the phenolic compounds of skins and seeds were defined. Finally, the genetic analysis of 16 red and 36 white varieties with molecular markers was followed. The molecular markers analysis was done with the Microsatellites/SSR method. The DNA isolation was done with the NucleoSpinⓇPlant II protocol. After that, 10 pairs of primers were added and the chain reaction of PCR took hold. Using the data analysis a dendrogramm was created, which illustrates the genetic resemblance of varieties.

description: Zur Untersuchung der Beschaffenheit von Lichtbogenfehlern in 48 V Kfz-Bordnetzen und für die Simulation der elektrischen, und gegebenenfalls funktionalen, Auswirkungen wird in dieser Arbeit ein neues Lichtbogenmodell entworfen, welches die in dieser Arbeit analysierten und definierten Anforderungen an Lichtbogenmodelle für Simulationen in 48 V Kfz-Bordnetzen erfüllen kann. Dieses Lichtbogenmodell kann mit Modellen von Bordnetzen kombiniert und so für die Analyse von fehlerhaften Bordnetzen verwendet werden. Anhand einer exemplarischen Bordnetzauslegung wird demonstriert, dass bei geschickter Wahl der Bordnetzabschlüsse und Verkabelungselemente eine intrinsische Sicherheit gegen serielle Lichtbögen erreicht werden kann. Für parallele Lichtbögen wird ein Diagnoseverfahren vorgestellt, welches in der Lage ist, diese zu detektieren und zu klassifizieren. Es werden für verschiedene Konfigurationen Worstcase-Abschätzungen bezüglich der Verlustenergie und somit der maximalen Reaktionszeit von Diagnoseverfahren durchgeführt. Das modellbasierte Diagnoseverfahren wird abschließend zunächst theoretisch hergeleitet und an einem konkreten Beispiel im Labor und mittels einer mit dem neuen Lichtbogenmodell nachgebildeten Simulation angewendet, validiert und diskutiert.

description: This thesis challenges the predominant historiographical view of the post-1960s political environment in America as moving inexorably to the right by developing a fresh perspective on liberalism during the 1980s, a decade often proclaimed as the apogee of conservatism. By presenting substantial archival evidence that liberal politicians and organisations remained a vibrant and dynamic political force during the so-called ‘Reagan Revolution’, this thesis examines how liberals resisted the conservative challenge and worked towards developing a political approach for the post-New Deal era. Through reinterpreting the impact of liberalism, and the principal vehicle of its promulgation, the Democratic Party, this study examines the development of liberalism from three distinct, though interrelated stands of enquiry: exploring strategies concerning the intellectual; institutional; and mobilisation aspects of liberalism. Ronald Reagan’s victory in 1980 created a powerful incentive to rethink the direction of liberalism. Taking Congress as its first focus, this thesis demonstrates how continued Democratic control of the House of Representatives placed Capitol Hill at the centre of an intellectual process to update liberalism for the 1980s. Yet grassroots liberal groups also began their own process of reform, professionalising operations and increasing political influence. Thus, part of this thesis’ significance lies in its examination of the interactions between elected officials and liberal groups in Reagan’s shadow, exploring the institutional ties that would fuel liberal campaigns during the decade. As will be demonstrated, these processes combined to foster a liberal recovery of sorts by the close of the decade. Changing tone, instead of substance, allowed liberals to survive the 1980s intact, and this thesis argues that the decade should be seen as a far more complicated period of political contest than conventional orthodoxy holds. By examining how the emergence of ‘identity politics’, principally through race and gender issues, interacted with the evolution of liberalism and energised political communities to establish more effective coalition-building efforts, this thesis reveals the gestation of a nascent coalition of women, minorities, and young professionals that, through successful mobilisation strategies, would provide the electoral base for liberal victories in later decades. As the 1980s progressed, negotiating liberalism in opposition allowed networks to form and develop to sustain the liberal philosophy, help liberals attain success at state and congressional level, and arguably facilitate Bill Clinton’s subsequent presidential triumph in 1992. Therefore, by tracing the evolution and transformation of liberalism through the decade, this thesis contributes to and enhances our understanding of 1980s American political history.

description: With the aid of a simple yet robust approach we investigate the influence of dissipationless and dissipative merging on galaxy structure, and the consequent effects on the scaling laws followed by elliptical galaxies. Our results suggest that ellipticals cannot be originated by parabolic merging of low mass spheroids only, even in presence of substantial gas dissipation. However, we also found that scaling laws such as the Faber-Jackson, Kormendy, Fundamental Plane, and the Mbh -sigma relations, when considered over the whole mass range spanned by ellipticals in the local universe, are robust against merging. We conclude that galaxy scaling laws, possibly established at high redshift by the fast collapse in pre-existing dark matter halos of gas rich and clumpy stellar distributions, are compatible with a (small) number of galaxy mergers at lower redshift.

description: To reduce the time-to-market and access to state-of-the-art techniques, CNN hardware mapping and deployment on embedded accelerators are often outsourced to untrusted third parties, which is going to be more prevalent in futuristic artificial intelligence of things (AIoT) systems. These AIoT systems anticipate horizontal collaboration among different resource-constrained AIoT node devices, where CNN layers are partitioned and these devices collaboratively compute complex CNN tasks. This horizontal collaboration opens another attack surface to the CNN-based application, like inserting the hardware Trojans (HT) into the embedded accelerators designed for the CNN. Therefore, there is a dire need to explore this attack surface for designing secure embedded hardware accelerators for CNNs. Towards this goal, in this paper, we exploited this attack surface to propose an HT-based attack called FeSHI. Since in horizontal collaboration of RC AIoT devices different sections of CNN architectures are outsourced to different untrusted third parties, the attacker may not know the input image, but it has access to the layer-by-layer output feature maps information for the assigned sections of the CNN architecture. This attack exploits the statistical distribution, i.e., Gaussian distribution, of the layer-by-layer feature maps of the CNN to design two triggers for stealthy HT with a very low probability of triggering. Also, three different novel, stealthy and effective trigger designs are proposed.

Aging and intermittency in a p-spin model of a glass

description: We numerically analyze the statistics of the heat flow between an aging system and its thermal bath, following a method proposed and tested for a spin-glass model in a recent Letter (P. Sibani and H.J. Jensen, Europhys. Lett.69, 563 (2005)). The present system, which lacks quenched randomness, consists of Ising spins located on a cubic lattice, with each plaquette contributing to the total energy the product of the four spins located at its corners. Similarly to our previous findings, energy leaves the system in rare but large, so called intermittent, bursts which are embedded in reversible and equilibrium-like fluctuations of zero average. The intermittent bursts, or quakes, dissipate the excess energy trapped in the initial state at a rate which falls off with the inverse of the age. This strongly heterogeneous dynamical picture is explained using the idea that quakes are triggered by energy fluctuations of record size, which occur independently within a number of thermalized domains. From the temperature dependence of the width of the reversible heat fluctuations we surmise that these domains have an exponential density of states. Finally, we show that the heat flow consists of a temperature independent term and a term with an Arrhenius temperature dependence. Microscopic dynamical and structural information can thus be extracted from numerical intermittency data. This type of analysis seems now within the reach of time resolved micro-calorimetry techniques.

title: The press and public on mental health: a corpus linguistic analysis of UK newspaper coverage of mental illness (1995-2014), compared with the UK National Attitudes to Mental Illness survey

description: Stigmas associated with mental illness have been shown to have a severe impact on the lives of people with mental health conditions. Mass media influence on the formation and perpetuation of stigmas is well-documented, and prior research has found the media to present several stigmatising representations of mental health issues. Due to the influence of the media in informing public opinion on mental illness, there have been concerted efforts in recent times to de-stigmatise press coverage of mental illness. However, whether coverage has changed in response to these efforts, and whether recognised stigmas and stereotypes have been dispelled from UK press discourse on mental health has not yet been fully established. To evaluate this, this study analysed a corpus of 12,000 UK newspaper articles from 1995-2014, with keyword and collocate analyses being implemented. The results of these analyses were compared between years of coverage and types of British newspaper, determining how UK press coverage of mental health issues changed over a 20-year period, with particular focus on the presence or absence of stigmas in this coverage. Keyword and collocate results were then compared with responses to questions in the UK national Attitudes to Mental Illness Survey (TNS BMRB, 2015), to ascertain the extent to which public attitudes correlated with press coverage of the same period. Decreases in key stigmas were uncovered in press coverage and found to correlate with decreases in negative public attitudes relating to these stigmas, as well as increases in press coverage of mental health stigma correlating with increased public awareness of stigma. However, whilst improvements in press coverage of mental illness were identified, stigmatising coverage was also found to have remained present to a significant degree in the UK press, demonstrating the need for continued de-stigmatisation efforts.

description: We investigate the sources of parity asymmetry in the CMB temperature maps using a pixel domain approach. We demonstrate that this anomaly is mainly associated with the presence of two pairs of high asymmetry regions. The first pair of peaks with Galactic coordinates $(l, b) = (212^\circ, -21^\circ)$ and $(32^\circ, 21^\circ)$ is associated with the Northern Galactic Spur and the direction of the dipole modulation of the power spectrum of the CMB anisotropy. The other pair ($(l, b)=(332^\circ, -8^\circ)$ and $(152^\circ, 8^\circ)$) is located within the Galactic plane (the Galactic Cold Spot and its antipodal partner). Similar asymmetric peaks, but with smaller amplitudes, belong to the WMAP/Planck Cold Spot and its partner in the Northern Galactic Spur. These local anomalies increase the odd-multipole power to a level consistent with Gaussian simulations. In contrast, the deficit of symmetric peaks is accompanied by a deficit in the even-multipole power and is the source of the parity asymmetry of the CMB temperature maps at the level of about 3 sigma. We also evaluate the influence of the quadrupole, which is another source of the even-multipole deficit. If the low quadrupole is an intrinsic feature of the theoretical model, it will reduce the significance of the parity asymmetry to around the 2 sigma level. We also investigate the relationship between the asymmetry of the power spectrum and the level of the parity asymmetry in the framework of a model with dipole modulation of a statistically uniform Gaussian signal. We show that these two anomalies are innately linked to each other.

description: In one-dimensional quantum systems with short-range interactions, a set of leading numerical methods is based on matrix product states, whose bond dimension determines the amount of computational resources required by these methods. We prove that a thermal state at constant inverse temperature $β$ has a matrix product representation with bond dimension $e^{\tilde O(\sqrt{β\log(1/ε)})}$ such that all local properties are approximated to accuracy $ε$. This justifies the common practice of using a constant bond dimension in the numerical simulation of thermal properties.

description: The measurement of a spin-$\half$ is modeled by coupling it to an apparatus, that consists of an Ising magnetic dot coupled to a phonon bath. Features of quantum measurements are derived from the dynamical solution of the measurement, regarded as a process of quantum statistical mechanics. Schrödinger cat terms involving both the system and the apparatus, die out very quickly, while the registration is a process taking the apparatus from its initially metastable state to one of its stable final states. The occurrence of Born probabilities can be inferred at the macroscopic level, by looking at the pointer alone. Apparent non-unitary behavior of the measurement process is explained by the arisal of small many particle correlations, that characterize relaxation.

description: SDSS J083942.11+380526.3 is an Iron Low-ionization Broad Absorption Line (FeLoBAL) quasar at z = 2.3, and Aoki et al. (2006) recently found the presence of an H alpha absorption line in the broad H alpha emission line. Motivated by an idea that this quasar may be a huge molecular gas reservoir in the early phase of quasar evolution, we made CO(J=3-2) observations of it using the Nobeyama Millimeter Array. No significant CO emission was detected; although an emission-like feature (2.5 sigma) was seen close (~ 2") to the quasar, we regard it as a noise. The obtained 3 sigma upper limit on the CO luminosity is L'_{{\rm CO}(J=3-2)} = 4.5 \times 10^{10} K km/s pc^2, which corresponds to M({\rm H}_2) = 3.6 times 10^10 M_{\odot} if we adopt the CO-to-H_2 conversion factor of 0.8 M_{\odot} (K km/s pc^2)^{-1}. This upper limit is comparable to L'_{{\rm CO}(J=3-2)} (and thus the molecular gas mass) detected in quasars and BAL quasars at z=1-3, and no sign of the presence of the huge amount of molecular gas in this FeLoBAL quasar was obtained.
