The learning and empowerment of people with schizophrenia
Creators: name: Price, Colleen A.
Publisher: name: University of British Columbia
Year: 2008

description: These days more and more schizophrenic people are being "mainstreamed" into society. This change in perspective has numerous implications for public policy, mental health services and families but, most importantly, for schizophrenic people. They have to "learn" how to live in the community and "normal" people have to adjust to and learn about schizophrenic people. Learning is a corollary of empowerment and it has become necessary to understand the subjective experience of schizophrenics. The purposes of this study were to interrogate Saljo's developmental model of learning conceptions from the perspective of schizophrenics, and to analyze the interrelationship between schizophrenic conceptions of learning and elements of empowerment. The researcher employed a qualitative methodology and interviewed ten men and ten women (n=20) with schizophrenia living in Vancouver about how they learn to survive with respect to six dimensions of living - housing, income, social support, work and education, leisure, mental health services. Saljo's model of learning conceptions and Davis' model of empowerment were operationalized to provide a framework within which to analyze the twenty transcripts. After the interviews were transcribed the author highlighted and analyzed excerpts concerned with learning and empowerment. Three procedures were used to examine the validity of the researcher's judgments pertaining to the transcripts and the researcher's final interpretation of the data. At the centre of this study was the notion that learning is a corollary of empowerment. The author found limitations within the two chief heuristic devices employed in this study (Saljo's conceptions of learning and Davis' elements of empowerment). Nevertheless, the twenty schizophrenics seemed to go about learning much like so-called "normal" populations. However, the same could not be said aboutempowerment. All felt significantly disempowered by the schizophrenic experience and an entire chapter was devoted to analyzing "subjective" and "objective" constructions of schizophrenia made by macro-level "authors" (e.g.government), macro/micro level authors (e.g. mental healthservices) and micro-level authors such as citizens on the street. It was concluded that disempowerment and marginalization result more from the way "normal" people construct schizophrenia than from the psychological disorganisation of the schizophrenics themselves. In future, it would be desirable to approach this problem from a critical perspective that focuses on the context as much as or more than the individual.

description: The aim of the thesis was to study the procedure of the interim measures and the temporary restraining order and in particular (to study) judgments related to them that have been issued and entered to cadastral records. Initially it was presented the purpose and the types of the interim measures, their reception conditions and the withdrawal of the judgments that order them. Then they were examined the interim measures of: (a) provisional seizure, (b) judicial sequestration, (c) note of mortgage and were analyzed the injunction about possession. Furthermore, it was presented in detail the meaning of the temporary restraining order, the conditions and terms about providing and examined the issue of withdrawal of temporary restraining order about prohibiting a change of legal status property. Ultimately, the thesis examined the registration and deletion of judgments about injunctions and the refusal of the head of cadastral office to the acting.

description: Energy minimality selects among possible configurations of a continuous body with and without cracks those compatible with assigned boundary conditions of Dirichlet-type. Crack paths are described in terms of curvature varifolds so that we consider both \textquotedblleft phase" (cracked or non-cracked) and crack orientation. The energy considered is gradient polyconvex: it accounts for relative variations of second-neighbor surfaces and pressure-confinement effects. We prove the existence of minimizers for such an energy. They are pairs of deformations and varifolds. The former ones are taken to be $SBV$ maps satisfying an impenetrability condition. Their jump set is constrained to be in the varifold support.

description: Considering a general mass matrix for quasi-degenerate neutrinos and treating the experimentally known oscillation parameters as inputs, we study the correlation between the degenerate mass scale $(m)$ and the mixing angle $θ_{13}$. We find that, corresponding to different values of $m$, there exist upper bounds on $θ_{13}$, so that a precise determination of the latter in future may put upper limit on the former, and vice versa. One can also find a possible correlation between $m$ and lower bound of $θ_{13}$, depending on the relative strength of the unperturbed degenerate mass matrix and the perturbation. The possible constraints on the parameters of few models of quasi-degenerate neutrinos are briefly discussed.

description: Vegetation is the most common and most reliable stabilizer of loose soil or sand. This ancient technique is for the first time cast into a set of equations of motion describing the competition between aeolian sand transport and vegetation growth. Our set of equations is then applied to study quantitatively the transition between barchans and parabolic dunes driven by the dimensionless fixation index $θ$ which is the ratio between dune characteristic erosion rate and vegetation growth velocity. We find a fixation index $θ_c$ below which the dunes are stabilized characterized by scaling laws.

description: This study is a literature review targeting studies about the linguistic development of Greek-speaking Down syndrome (DS) people. The studies found were later divided in chapters, in accordance to their subject, and were presented in detail with respect to their goals, participants, methodology and conclusions. At the same time, a presentation of respective studies with participants speaking other languages took place, in order to compare each others’ conclusions. By presenting the studies concerning Greek-speaking participants, a lack of study quantity becomes obvious. Nevertheless, the presented studies are considered positively in terms of quality, even though some negative points appear

description: We include the standard-model (SM) leptons in a recently proposed framework for the generation of quark mass ratios and Cabibbo-Kobayashi-Maskawa (CKM) mixing angles from an SU(3) family gauge interaction. The set of SM-singlet scalar fields describing the spontaneous breaking is the same as employed for the quark sector. The imposition at tree-level of the experimentally correct Pontecorvo-Maki-Nakagawa-Sakata (PMNS) mixing matrix, in the form of a tri-bi maximal structure, fixes several of the otherwise free parameters and renders the model predictive. The normal hierarchy among the neutrino masses emerges from this scheme.

description: Conifold geometries have recieved a lot of attention in string theory and string-inspired cosmology recently, in particular the Klebanov-Strassler background that is known as the "warped throat". It is our intention in this article to give a pedagogical explanation for the singularity resolution in this geometry and emphasise its connection to geometric transitions. The first part focuses on the gauge theory dual to the Klebanov-Strassler background, which we also explain from a T-dual intersecting branes scenario. We then make the connection to the Gopakumar-Vafa conjecture for open/closed string duality and summarise a series of papers verifying this model on the supergravity level. An appendix provides extensive background material about conifold geometries. We pay special attention to their complex structures and re-evaluate the supersymmetry conditions on the background flux in constructions with fractional D3-branes on the singular (Klebanov-Tseytlin) and resolved (Pando Zayas-Tseytlin) conifolds. We agree with earlier results that only the singular solution allows a supersymmetric flux, but point out the importance of using the correct complex structure to reach this conclusion.

description: {The Galactic centre (GC) is a unique astrophysical laboratory to study the stellar population of galactic nuclei because it is the only galactic nucleus whose stars can be resolved down to milliparsec scales. However, the extreme and spatially highly variable interstellar extinction towards the GC poses a serious obstacle to photometric stellar classification.} {Our goal is to identify hot, massive stars in the nuclear stellar disc (NSD) region through combining near-infrared (NIR) and mid-infrared (MIR) photometry, and thus to demonstrate the feasibility of this technique, which may gain great importance with the arrival of the James Webb Space Telescope (JWST).} {We combined the GALACTICNUCLEUS NIR survey with the IRAC/Spitzer MIR survey of the GC. We applied the so-called Rayleigh-Jeans colour excess (RJCE) de-reddening method to our combined NIR-MIR data to identify potential hot stars in colour-magnitude diagrams (CMDs).} {Despite the very low angular resolution of IRAC we find 12 clear candidates for young massive stars among the $1\,065$ sources that meet our selection criteria. Seven out of these 12 stars are previously known hot, massive stars belonging to the Arches and Quintuplet clusters, as well as sources detected by the Hubble Space Telescope/NICMOS Paschen-$α$ survey. Five of our massive star candidates have not been previously reported in the literature.} {We show that the RJCE method is a valuable tool to identify hot stars in the GC using photometry alone. Upcoming instruments with high angular resolution MIR imaging capabilities such as the JWST could surely make more substantial use of this de-reddening method and help establish a far more complete census of hot, young stars in the GC area than what is possible at the moment.}

The Disk Around CoKu Tau/4: Circumbinary, not Transitional

description: CoKu Tau/4 has been labeled as one of the very few known transition disk objects: disks around young stars that have their inner disks cleared of dust, arguably due to planetary formation. We report aperture-masking interferometry and adaptive optics imaging observations showing that CoKu Tau/4 is in fact a near-equal binary star of projected separation $\sim$53 mas ($\sim$8 AU). The spectral energy distribution of the disk is then naturally explained by inner truncation of the disk through gravitational interactions with the binary star system. We discuss the possibility that such ``unseen'' binary companions could cause other circumbinary disks to be labeled as transitional.

description: We study the Mott transition, antiferromagnetism and superconductivity in layered organic conductors using Cellular Dynamical Mean Field Theory for the frustrated Hubbard model. A d-wave superconducting phase appears between an antiferromagnetic insulator and a metal for $t^{\prime}/t=0.3-0.7 $, or between a nonmagnetic Mott insulator (spin liquid) and a metal for $t^{\prime}/t\geq 0.8$, in agreement with experiments on layered organic conductors including $κ$-(ET)$_{2}$Cu$_{2}$(CN)$_{3}$. These phases are separated by a strong first order transition. The phase diagram gives much insight into the mechanism for d-wave superconductivity. Two predictions are made.

description: The scattering of surface plasmons polaritons by a one-dimensional defect of the surface is theoretically studied, by means of both Rayleigh and modal expansions. The considered defects are either relief perturbations or variations in the permittivity of the metal. The dependence of transmission, reflection and out-of-plane scattering on parameters defining the defect is presented. We find that the radiated energy is forwardly directed (with respect to the surface plasmon propagation) in the case of an impedance defect. However, for relief defects, the radiated energy may be directed into backward or forward (or both) directions, depending on the defect width.

description: Using a reformulated Kubo formula we calculate the zero-energy minimal conductivity of bilayer graphene taking into account the small but finite trigonal warping. We find that the conductivity is independent of the strength of the trigonal warping and it is three times as large as that without trigonal warping, and six times larger than that in single layer graphene. Although the trigonal warping of the dispersion relation around the valleys in the Brillouin zone is effective only for low energy excitations, our result shows that its role cannot be neglected in the zero-energy minimal conductivity.

description: In the last two years we have witnessed the exciting experimental discovery of soft matter with nontrivial quasiperiodic long-range order - a new form of matter termed a soft quasicrystal. Two groups have independently discovered such order in soft matter: Zeng et al. [Nature 428 (2004) 157] in a system of dendrimer liquid crystals; and Takano et al. [J. Polym. Sci. Polym. Phys. 43 (2005) 2427] in a system of ABC star-shaped polymers. These newly discovered soft quasicrystals not only provide exciting platforms for the fundamental study of both quasicrystals and of soft matter, but also hold the promise for new applications based on self-assembled nanomaterials with unique physical properties that take advantage of the quasiperiodicity, such as complete and isotropic photonic band-gap materials. Here we provide a concise review of the emerging field of soft quasicrystals, suggesting that the existence of two natural length-scales, along with 3-body interactions, may constitute the underlying source of their stability.

description: A striking feature of quantum error correcting codes is that they can sometimes be used to correct more errors than they can uniquely identify. Such degenerate codes have long been known, but have remained poorly understood. We provide a heuristic for designing degenerate quantum codes for high noise rates, which is applied to generate codes that can be used to communicate over almost any Pauli channel at rates that are impossible for a nondegenerate code. The gap between nondegenerate and degenerate code performance is quite large, in contrast to the tiny magnitude of the only previous demonstration of this effect. We also identify a channel for which none of our codes outperform the best nondegenerate code and show that it is nevertheless quite unlike any channel for which nondegenerate codes are known to be optimal.

Abstract Entrectinib (Rozlytrek®) is an orally active, CNS-penetrant, small-molecule, selective inhibitor of the tropomyosin receptor tyrosine kinases TRKA/B/C [encoded by the neurotrophic tyrosine receptor kinase (NTRK) genes NTRK1/2/3, respectively], the proto-oncogene tyrosine-protein kinase ROS1 (ROS1) and the anaplastic lymphoma kinase gene (ALK). It is approved for the treatment of adults and paediatric patients aged ≥ 12 years with NTRK fusion-positive (NTRK+) solid tumours and adults with ROS1 fusion-positive (ROS1+) non-small-cell lung cancer (NSCLC). In trials in adults, entrectinib induced clinically meaningful and durable systemic responses in tyrosine kinase inhibitor (TKI)-naïve patients with locally-advanced or metastatic NTRK+ solid tumours or ROS1+ NSCLC, irrespective of the presence or absence of CNS metastases at baseline. Moreover, entrectinib demonstrated substantial intracranial efficacy in patients with baseline CNS metastases. Entrectinb efficacy in paediatric patients was established on the basis of extrapolation of clinical trial data from adults with NTRK+ solid tumours and children and adolescents aged NTRK+ CNS/solid tumours. Entrectinib was generally well tolerated, with a manageable safety profile. Thus, entrectinib expands the range of treatment options for advanced NTRK+ solid tumours and ROS1+ NSCLC, and may be of particular value in patients with existing CNS metastases and those who are at risk of developing CNS metastases © Springer Nature Switzerland AG 2021

Gas Accretion by Globular Clusters and Nucleated Dwarf Galaxies and the Formation of the Arches and Quintuplet Clusters

Publisher: name: arXiv
Year: 2007
Subjects: subject: Astrophysics (astro-ph)

description: We consider here the collective accretion of gas by globular clusters and dwarf galaxies moving through the interstellar medium. In the limit of high velocity and/or sound speed of the ISM, the collective potential of the cluster is insufficient to accrete significant amounts of gas, and stars within the systems accrete gas individually. We show, however, that when the sound speed or the relative velocity of the ambient medium is less than the central velocity dispersion of the cluster, it is accreted into the collective potential of the cluster prior to being accreted onto the individual stars within the cluster. The collective rate is strongly enhanced relative to the individual rates. This effect may potentially modify the white dwarf cooling sequence in globular clusters with low-inclination and low-eccentricity Galactic orbits, and lead to the rejuvenation of some marginally surviving cores of globular clusters and nucleated dwarf galaxies near the Galactic center. Such effects will only occur rarely, but may explain the existence of clusters of young, massive stars near the Galactic center.

description: In the context of loop quantum cosmology, we consider an inflationary era driven by a canonical scalar field and occurring in the semiclassical regime, where spacetime is a continuum but quantum gravitational effects are important. The spectral amplitude and index of scalar perturbations on an unperturbed de Sitter background are computed at lowest order in the slow-roll parameters. The scalar spectrum can be blue-tilted and far from scale invariance, and tuning of the quantization ambiguities is necessary for agreement with observations. The results are extended to a generalized quantization scheme including those proposed in the literature. Quantization of the matter field at sub-horizon scales can provide a consistency check of such schemes.

description: We show that for any positive integer $m\ge 1$, $m$-relator quotients of the modular group $M = PSL(2,\mathbb{Z})$ generically satisfy a very strong Mostow-type \emph{isomorphism rigidity}. We also prove that such quotients are generically "essentially incompressible". By this we mean that their "absolute $T$-invariant", measuring the smallest size of any possible finite presentation of the group, is bounded below by a function which is almost linear in terms of the length of the given presentation. We compute the precise asymptotics of the number $I_m(n)$ of \emph{isomorphism types} of $m$-relator quotients of $M$ where all the defining relators are cyclically reduced words of length $n$ in $M$. We obtain other algebraic results and show that such quotients are complete, Hopfian, co-Hopfian, one-ended, word-hyperbolic groups.

description: Negative probabilities emerged at intermediate steps in various attempts to predict the distributions of quantum interference. There is no consensus on their meaning yet. It has been suggested (Khrennikov, 1998) that negative probabilities require the existence of unsuspected correlations between detection events.We evaluate this claim in light of several representative experiments. In our assessment, some of its implications are in good agreement with the data.

description: Recolliding electrons are responsible for many of the interesting phenomena observed in the interaction of strong laser fields with atoms and molecules. We show that in multielectron targets such as C60 a new important recollision pathway opens up: the returning electron may excite collective modes even if the laser frequency is far off-resonant. We formulate a simple analytical theory which predicts that the recollision-induced excitation of collective modes should dominate over the "usual" harmonic generation yield at 800nm wavelength. In this case the tomographic imaging of complex multielectron systems may be obscured. We employ a time-dependent density functional model of C60 and show that with increasing laser wavelength the dynamics becomes more and more single active electron-like, suggesting that long wavelengths are to be preferred for imaging purposes.

We suggest these may be attributable to holes in the condensate cloud layers in the atmosphere of a single sub-stellar object, but cannot at present completely rule out the role of binarity as the possible cause. We also identify this object as a blue L dwarf, and explore the similar observable characteristics of these objects with those of the L-T transition. From this comparison we suggest that the temperature (and thus spectral type) at which the condensate cloud later begins to break-up/rain out, may be highly sensitive to small variations in metallicity. However, the JH-band spectrum of this object does not resemble that of the known L sub-dwarfs, and therefore extreme metal deficiency may not in fact be responsible for the discordant features. We estimate a spectral type of L9+/-1, and measure a large proper-motion of μ_(tot)=1.65"+/-0.03" per year. Also, a spectrophotometric distance of 8.2pc is estimated, possibly making this object the nearest easily observable single L-T transition object in the southern hemisphere.

litter quality

description: The visual assessment of the litter quality in broiler chickens, valuable indicator of birds’ welfare, is commonly used in scientific studies or on-field in broiler chickens barns. Visual assessment of litter quality is highly feasible but it may be considered as subjective, depending on the assessor and not reflecting the evolution of physical parameters such as the litter moisture. This study aimed to evaluate the validity, the reliability between several assessors and the repeatability for a same assessor of three visual scores from the Welfare Quality (one score) and the ClassyFarm protocols (two complementary scores: Friability and Humidity scores).

description: Neural interfaces, bridging brain physiology and external electronic devices, allow brain function monitoring for neurochemistry research or clinical purposes. Despite recent advances in monitoring electrical brain activity, measuring chemical neurotransmission remains a significant challenge. We recently developed a platform for robust and ultrasensitive detection of dopamine, an essential neurotransmitter that underlies several brain disorders, based on graphene multitransistor arrays (gMTAs) functionalized with a selective DNA aptamer. Not only did we achieve the lowest limit-of-detection ever reported (1 aM), but we could also detect dopamine with great sensitivity in complex samples such as artificial cerebral spinal fluid and brain homogenate, including in a mouse model of Parkinson's Disease. Herein, we present a novel nanobioelectronic neural interface based on gMTAs that allows monitoring of neurotransmitter opto-evoked release in ex vivo brain slices of transgenic mice. Optimizing our gMTAs' fabrication process, we developed an interface with higher sensor density that accommodates mice's brain slices and allows optogenetic modulation through integrated micro-LEDs. The platform presented in this work can lead the way to novel neurotransmitter sensors suitable for real-world academic and pre-clinical pharmaceutical research and clinical diagnosis.

description: It is shown that the collision integral describing the nonlocal character of collisions leads to the same mean-field fluctuations as proposed by Boltzmann-Langevin pictures. It is argued that this appropriate collision integral contains the fluctuation-dissipation theorems in equilibrium itself and therefore there is no need to assume additionally stochasticity. This leads to tremendous simplifications in numerical simulation schemes.

description: We derive the complete spectrum of gravitational waves induced by primordial scalar perturbations ranging over all observable wavelengths. This scalar-induced contribution can be computed directly from the observed scalar perturbations and general relativity and is, in this sense, independent of the cosmological model for generating the perturbations. The spectrum is scale-invariant on small scales, but has an interesting scale-dependence on large and intermediate scales, where scalar-induced gravitational waves do not redshift and are hence enhanced relative to the background density of the Universe. This contribution to the tensor spectrum is significantly different in form from the direct model-dependent primordial tensor spectrum and, although small in magnitude, it dominates the primordial signal for some cosmological models. We confirm our analytical results by direct numerical integration of the equations of motion.

description: We study by exact diagonalization, in the lowest Landau level approximation, the Coulomb interaction problem of N = 4 and N = 6 quantum dot in the limit of zero Zeeman coupling. We find that meron excitations constitute the lowest lying states of the quantum dots. This is based on a mapping between the excitations of the dot and states of the Haldane-Shastry spin chain.

description: Background: The Advanced Training in Clinical Simulation (ATCS) at University of Medicine and Pharmacy, Ho Chi Minh City, Vietnam is one of a few Simulation Centers in Southeast Asian has been accredited by Society for Simulation in Healthcare (SSH). Simulation-based education activities at ATCS focus on enhancing students’ clinical skills and promoting patient safety. This study aims to examine the effects of applying deliberate practice (DP) on students’ performance and learning experience in basic life support (BLS) skills.



Methods: A Quasi-Experimental Study was conducted among 398 second-year medical students. A volunteer-based deliberate practice session was provided to these students after their basic life support course. The intervention group included 280 students participating in the practice session, while the other 118 students not participating in the practice session were in the control group. We collected students’ summative OSCE scores and their feedback on the deliberate practice session. Independent t-test and theme analysis were employed for data analysis.



Results: Students in the intervention group had better performance than those of control group. The intervention group’s mean score was 34.4 ± 2.54 while the control group’s mean score was 32.9 ± 4.09 (p<0.001). The passing rate was also higher in the intervention group than in the control group (95% versus 84%, p=0.003). Students revealed that the deliberate practice session was helpful in identifying the competency gaps and in developing study plans to improve cardiopulmonary resuscitation skills. This resulted in their better preparation for the final examination.



Discussions & Conclusions: Our findings aligned with previous studies on the effectiveness of deliberate practice on students’ learning experience and performance. However, it has not been a common practice at our university. This study calls for more attention on improving simulation-based education approach at ATCS with more emphasis on students’ discrete goal and assessors’ actionable feedback. Further studies need to evaluate the educational impact on students’ skill retention in clinical settings and the effects of delivering deliberate practice session on faculties’ facilitating skills.
Flipped and Unflipped SU(5) as Type IIA Flux Vacua

description: On Type IIA orientifolds with flux compactifications in supersymmetric AdS vacua, we for the first time construct SU(5) models with three anti-symmetric {\bf 10} representations and without symmetric {\bf 15} representations. We show that all the pairs of the anti-fundamental {\bf \bar 5} and fundamental {\bf 5} representations can obtain GUT/string-scale vector-like masses after the additional gauge symmetry breaking via supersymmetry preserving Higgs mechanism. Then we have exact three {\bf \bar 5}, and no other chiral exotic particles that are charged under SU(5) due to the non-abelian anomaly free condition. Moreover, we can break the SU(5) gauge symmetry down to the SM gauge symmetry via D6-brane splitting, and solve the doublet-triplet splitting problem. Assuming that the extra one (or several) pair(s) of Higgs doublets and adjoint particles obtain GUT/string-scale masses via high-dimensional operators, we only have the MSSM in the observable sector below the GUT scale. Then the observed low energy gauge couplings can be generated via RGE running if we choose the suitable grand unified gauge coupling by adjusting the string scale. Furthermore, we construct the first flipped SU(5) model with exact three {\bf 10}, and the first flipped SU(5) model in which all the Yukawa couplings are allowed by the global U(1) symmetries.

Education, training, manpower planning and the persistence of manpower shortages : the case of Thailand’s tourism industry
Creators: name: Prasirtsuk, Wannapa
Publisher: name: University of British Columbia

description: Although manpower and educational planning have been used in some developing countries for a considerable time to ensure an adequate supply of qualified manpower for the economy, the problem of manpower shortages still persists. An analysis of the reasons underlying the presumed failure of planning processes to ensure adequate supplies of qualified manpower for individual sectors of the economy forms the basis of this study. The issue was examined through an examination of the case of one specific sector of Thailand's economy: the tourism industry. In particular, the study sought to ascertain whether the shortages are the result of problems with the national manpower and educational planning models or whether they reflect issues intrinsic to individual economic sectors. The study draws on the literature in three areas: manpower planning, the relationship between manpower and educational planning, and employment and manpower development planning in the tourism industry. To explore possible explanations for the persistence of manpower shortages in the Thai tourism industry, two kinds of data were used: documentary and interview data. The interviews were conducted with three groups of key informants: employers in the tourist business, providers of tourism education and training, and senior government officials who are involved in manpower and educational planning. A total of 85 people in four tourist centres in Thailand were interviewed. The analysis of the data confirms that there is a mismatch between manpower demand and supply in the Thai tourism industry with demand significantly surpassing supply. The study concluded that there are limitations in the manpower and educational planning models, and that there is a lack of some of the conditions required for their optimal functioning, but that the mismatch between supply and demand in the Thai tourism industry is more fully explained by features intrinsic to the industry itself. A Abstract balance between manpower demand and supply in any sectors would be improved by having manpower planning at the macro level well meshed with educational planning, and by developing linkages between two levels of planning: the national and industry level. More importantly, however, within the industry itself, those involved have to take a planning stance by diagnosing the way their own sector operates and collaborating to rectify the problems they find. This study has implications for policy and improved practice of the planning, production and development of manpower required by the Thai tourism industry. It also has lessons for other sectors of the Thai economy as well as other developing countries.

description: We report infrared studies of the Landau level (LL) transitions in single layer graphene. Our specimens are density tunable and show \textit{in situ} half-integer quantum Hall plateaus. Infrared transmission is measured in magnetic fields up to B=18 T at selected LL fillings. Resonances between hole LLs and electron LLs, as well as resonances between hole and electron LLs are resolved. Their transition energies are proportional to $\sqrt{B}$ and the deduced band velocity is $\tilde{c}\approx1.1\times10^6$ m/s. The lack of precise scaling between different LL transitions indicates considerable contributions of many-particle effects to the infrared transition energies.

description: We introduce the concept of Loday algebroids, a generalization of Courant algebroids. We define the naive cohomology and modular class of a Loday algebroid, and we show that the modular class of the double of a Lie bialgebroid vanishes. For Courant algebroids, we describe the relation between the naive and standard cohomologies and we conjecture that they are isomorphic when the Courant algebroid is transitive.
