description: We propose a definition of the Casimir energy for free lattice fermions. From this definition, we study the Casimir effects for the massless or massive naive fermion, Wilson fermion, and (Möbius) domain-wall fermion in $1+1$ dimensional spacetime with the spatial periodic or antiperiodic boundary condition. For the naive fermion, we find an oscillatory behavior of the Casimir energy, which is caused by the difference between odd and even lattice sizes. For the Wilson fermion, in the small lattice size of $N \geq 3$, the Casimir energy agrees very well with that of the continuum theory, which suggests that we can control the discretization artifacts for the Casimir effect measured in lattice simulations. We also investigate the dependence on the parameters tunable in Möbius domain-wall fermions. Our findings will be observed both in condensed matter systems and in lattice simulations with a small size.

description: The archaeal L7Ae protein is an integral component of three functionally distinct macromolecular ribonucleoprotein complexes: the 50S large ribosomal subunit, the C/D box modification particles and the H/ACA box particles To better understand the function of the L7Ae protein and to investigate the diversity of RNAs specifically associated with this protein, immuno-affinity chromatography was used to isolate the sRNAs associated with L7Ae and RT-PCR was employed to construct a cDNA library. The isolated sRNAs were divided in different groups based on the presence of common known sequence and structural motifs and/or genomic location. Group one contained six RNAs that exhibited the, features characteristic of the canonical C/D box archaeal sRNAs and one RNA representative of the archaeal H/ACA sRNA family. Group two contained fourteen sequences that were encoded either within, or overlapping the 5' end or 3' end of ORFs mostly coding for transposases. Interestingly, one of the clones in this group corresponded to the 5'-untranslated region (UTR) of L7Ae mRNA, indicating that L7Ae protein is able to interact with its own mRNA. The relevance of this interaction for the expression of L7Ae protein was further analyzed using a S. solfataricus in vitro translation system. Group three contained three sequences form intergenic regions. Group four contained five antisense sequences complementary to the 5' end, 3' end or internal regions within annotated open-reading frames (ORFs) and two sequences antisense to bona-fide C/D box sRNAs. Group five contained two sequences corresponding to internal regions of 7S RNA of the signal recognition particle (SRP). Additionally, in the aim to better understand the versatility of L7Ae in the interaction with various sRNA substrates, we introduced mutations in a model C/D box sRNA and monitored the impact of mutation on the protein binding ability and on the methylation function of the sRNA. My data suggest that L7Ae protein might have an important regulatory role in archaeal cells, serving as a primary RNA-binding factor in various complexes with distinct function. In addition, the results obtained in this study set the stage to further characterize all the sequences identified in this screening and to elucidate their function.

description: A three-level system attached to three thermal baths is manipulated to be a microscopic thermal device integrating a valve, a refrigerator, an amplifier, and a thermometer in the quantum regime, via tuning the inner coupling strength of the system and the temperatures of the external baths. We discuss the role of the inner coupling as well as the steady-state quantum coherence in these thermal functions using the Redfield master equation under a partial secular approximation. A high-sensitive thermometer for the low-temperature terminal can be established without the assistance from the inner coupling of the system. Our study of this multifunctional thermal device provides a deeper insight to the underlying quantum thermodynamics associated with the quantum coherence.

On the Dirac field in the Palatini form of 1/R gravity

description: In recent papers (astro-ph/0306630, gr-qc/0312041) I have argued that the observed cosmological acceleration can be accounted for by the inclusion of a 1/R term in the gravitational action in the Palatini formalism. Subsequently, Flanagan (astro-ph/0308111, gr-qc/0403063) argued that this theory is equivalent to a scalar-tensor theory which produces corrections to the standard model that are ruled out experimentally. In this article I examine the Dirac field coupled to 1/R gravity. The Dirac action contains the connection which was taken to be the Christoffel symbol, not an independent quantity, in the papers by Flanagan. Since the metric and connection are taken to be independent in the Palatini approach it is natural to allow the connection that appears in the Dirac action to be an independent quantity. This is the approach that is taken in this paper. The resulting theory is very different and much more complicated than the one discussed in Flanagan's papers.

description: We study the propagation and diffusion of electric charge fluctuations in the Bjorken hydrodynamic model with both white and Catteneo noise using purely numerical methods. We show that a global lattice of noise fluctuations is required to fully calculate the two-point correlators of charge. We solve the stochastic differential equations that arise from the charge conservation equation on the lattice. We explicitly identify the self-correlation term in the case of Catteneo noise and provide a physical interpretation. We provide a numerical recipe to remove this contribution from the full two-point correlators. Finally, we calculate the balance functions for charged hadrons. By limiting the speed of signal propagation, we observe the expected narrowing of the balance functions after removing the self-correlations.

Subjects: subject: High Energy Physics - Lattice (hep-lat)
subject: FOS: Physical sciences

description: At a fixed lattice spacing, as determined by say m_ρ, adding additional fermion flavors to a dynamical simulation produces rougher gauge field configurations at the lattice scale. For domain wall fermions, these rough configurations lead to larger residual chiral symmetry breaking and larger values for the residual masses, m_{res}. We discuss ongoing attempts to reduce chiral symmetry breaking for N_f = 3 dynamical domain wall fermion simulations by different smoothing choices for the gauge fields.

description: We study the nonequilibrium dynamics of a Bose-Einstein condensate which is split in a harmonic trap by turning up a periodic optical lattice potential. We evaluate the dynamical evolution of the phase coherence along the lattice and the number fluctuations in individual lattice sites within the stochastic truncated Wigner approximation when several atoms occupy each site. We show that the saturation of the number squeezing at high lattice strengths, which was observed in recent experiments by Orzel et. al., can be explained by the nonadiabaticity of the splitting.

description: We present a general growth model based on non-extensive statistical physics is presented. The obtained equation is expressed in terms of nonadditive $q$ entropy. We show that the most common unidimensional growth laws such as power law, exponential, logistic, Richards, Von Bertalanffy, Gompertz can be obtained. This model belongs as a particular case reported in (Physica A 369, 645 (2006)). The new evolution equation resembles the "universality" revealed by West for ontogenetic growth (Nature 413, 628 (2001)). We show that for early times the model follows a power law growth as $ N(t) \approx t ^ D $, where the exponent $D \equiv \frac{1}{1-q}$ classifies different types of growth. Several examples are given and discussed.

description: Dopo la seconda guerra mondiale ci sono stati il regolamento degli aiuti concessi sulla base del Lend-lease, l’istituzione del sistema di Bretton Woods, il prestito alla Gran Bretagna e, infine, il piano Marshall. Riflettendo su quel periodo ho proposto una mia legge delle politiche economiche alternative: dopo un lungo dibattito su quale alternativa scegliere – per esempio, dazi doganali oppure svalutazione del cambio in Inghilterra nel 1930 e 1931, istituzioni internazionali come a Bretton Woods oppure approccio delle valute chiave del prestito alla Gran Bretagna – si finisce spesso per adottare entrambe le alternative (il che rovina la possibilità di usare l’esperimento come “test” di teorie economiche). Non che abbia l’intenzione di esaltare il pragmatismo puro che non poggia su alcuna teoria. Tuttavia, negli ultimi anni, ho perso parte della mia ammirazione, se mai ne ho avuta molta, per un approccio ideologico o dogmatico ai problemi economici. After the Second World War there were the regulation of the aid granted under the Lend-Lease, the establishment of the Bretton Woods system, the loan to Britain and, finally, the Marshall Plan. Looking back on that period, I proposed an alternative economic policies of my law: after a long debate as to which alternative to choose - for example, customs duties or devaluation of the currency in England in 1930 and 1931, international institutions such as the Bretton Woods approach or key currency of the loan to Britain - it often ends up taking both alternatives (which ruin the possibility of using the experiment as "test" of economic theories). Not that I intend to bring out the pure pragmatism that is not based on any theory. However, in recent years, I lost part of my admiration, if I ever had much, for ideological or dogmatic approach to economic problems. JEL Codes: E44, G1, G18, G28

Contested imagined communities : higher education for ethnic minority students in Vietnam
Creators: name: Tran, Linh Thuy
Publisher: name: University of British Columbia
Year: 2011

description: As a country with 54 ethnic groups, including 53 officially designated "ethnic minority groups," Vietnam has recognized the importance of enhancing education for ethnic minorities. However, despite the government's efforts to increase educational opportunities for ethnic minority students, the latter often do not have access to the same education as their counterparts of the major ethnic group, the Kinh. In this study, the concept of "imagined communities" (Anderson 1991) is applied to analyze national governmental policies on ethnic minorities, curricular structure in the Department of Ethnic Minority Cultures at the Hanoi University of Culture, Vietnam, and the perspectives of professors and students in the department. Three months of field research were conducted in Vietnam, and included: (a) an analysis of national and institutional policy documents, (b) observation at the university, and (c) interviews with professors and ethnic minority students enrolled in the program. The findings of this study show that imagined communities envisioned for ethnic minority students by the government, professors and students themselves are diverse and contested. The contestation of imagined communities on higher education for ethnic minority students in Vietnam shows a clear intersection between power and knowledge. Through education, the government, with its power, has great influence on educational activities which affect the identities of ethnic minority students. Educational settings, in some sense, become the place of social and cultural reproduction where "organic" knowledge of ethnic minority students is discounted. Finally, this study gives a description of my personal transformation after conducting this research. It shows how this research has changed my own mindset and thinking about ethnic minority cultures in general and higher education for ethnic minority students in Vietnam in particular.

description: Diabetes induced complications like peripheral vascular disease (PVD) and neuropathy promote the formation of wounds and lead to impaired wound healing in diabetic patients. Early detection and effective, low cost treatment options are key factors to improve the patient's quality of life as well as to reduce health care costs. New therapeutic approaches like percutaneous auricular vagus nerve stimulation (aVNS) promise to reactivate the autonomous nervous system (ANS), promote wound healing or prevent the formation of new wounds. To monitor the effects of aVNS on the ANS, the pulse plethysmography (PPG) signal of healthy and diabetic patients was recorded and analyzed in the course of a pilot study. Parameters of interest were the systolic-diastolic volume deflection, the reflection time and the reflection index. For the latter two, the respective incident and reflected pulse waves in each cardiac cycle need to be extracted from the PPG signal. This was achieved by Gaussian peak fitting, using an iterative least-square fitting algorithm. The algorithm was validated by the use of artificial and real measured pulse signals. For most regular PPG signals, fitting errors of < 5 % could be achieved. Using appropriate quality control mechanisms, highly automated and accurate analysis is possible. Besides a decomposition of incident and reflected waves, the original PPG signal can also be reconstituted from the Gauss parameters, and thus may help to save memory. The feasibility of analyzing full datasets from the pilot study was tested. In this analysis, differences between single healthy and diabetic patients could be observed. Thus, the presented method holds potential for diagnostics and a possible monitoring of therapeutic effects. Long-term effects were not assessed and further analysis is necessary.

description: The usual paradigm of open quantum systems falls short when the environment is actually coupled to additional fields or components that drive it out of equilibrium. Here we explore the simplest such scenario, by considering a two level system coupled to a first thermal reservoir that in turn couples to a second thermal bath at a different temperature. We derive a master equation description for the system and show that, in this situation, the dynamics can be especially rich. In particular, we observe prethermalization, a transitory phenomenon in which the system initially approaches thermal equilibrium with respect to the first reservoir, but after a longer time converges to the thermal state dictated by the temperature of the second environment. Using analytical arguments and numerical simulations, we analyze the occurrence of this phenomenon, and how it depends on temperatures and coupling strengths. The phenomenology gets even richer if the system is placed between two such non-equilibrium environments. In this case, the energy current through the system may exhibit transient features and even switch direction, before the system eventually reaches a non-equilibrium steady state.

description: New citrus rootstocks were developed by sexual hybridization and evaluated for vigor, health, uniformity from seed, and resistance to disease. Hybrid rootstocks with favorable combinations of traits were budded with common scions and established in replicated field trials along with standard rootstocks at several locations for evaluation of effects on tree health, tree size, fruit quality, and yield. Significant differences were observed in performance of different rootstocks. One new USDA hybrid rootstock, HRS-812, produced healthy standard-size trees with excellent yields in Florida trials with 'Valencia' (Citrus sinensis [L.] Osbeck) and 'Ambersweet' orange, 'Fallglo' citrus hybrid, and 'Sunburst' mandarin (C. reticulata Blanco) scions and appeared resistant to tristeza virus. Rootstock trials at two locations in Puerto Rico with 'Dancy' mandarin and 'Chironja' scions on HRS-812 rootstock gave good tree growth and excellent yields. The information collected in these trials can be useful in selecting rootstocks for new plantings of citrus.

description: In Puerto Rico the production of taro under upland conditions is concentrated in the central mountains of the main island. Various limitations concerning the field management were identified and documented. A research project has been conducted to obtain quantitatively based information for the improvement of the management practices for taro production under upland conditions in Puerto Rico. Experiments included evaluation for sett size, plant spacing, weed interference, and nitrogen sidedressing. Results showed that adequate yield can be obtained by using planting setts of 170 g or heavier. Plants from setts of 114 g and lighter had reduced productivity and plant dry weight. Regardless of the sett size, the use of 38.1 cm as planting distance in the row decreased yield and dry weight. Neither sett size nor plant spacing had a significant effect on the percentage of dry matter partitioning into the corm at harvest. Planting at 45.7 cm, rather than at 61.0 cm, may result in more leaf area per land area early in the crop cycle, thus reducing weed interference. There was a significant negative relationship between taro leaf area index and combined weed dry weight. Absence of nitrogen in the fertilizer tends to reduce plant dry weight, but levels of nitrogen side-dressing equivalent to 42, 96, and 138 kg/ha did not make a difference on plant dry weight or yield.

description: It has been shown recently that the universal dc spin conductivity of two-dimensional electrons with a Rashba spin-orbit interaction is canceled by vertex corrections in a weak scattering regime. We prove that the zero bulk spin conductivity is an intrinsic property of the free-electron Hamiltonian and scattering is merely a tool to reveal this property in terms of the diagrammatic technique. When Zeeman energy is neglected, the zero dc conductivity persists in a magnetic field. Spin conductivity increases resonantly at the cyclotron frequency and then decays towards the universal value.

description: Mott gap excitations in the high-Tc superconductor of the optimal doped YBa2Cu3O7-d (Tc = 93 K) have been studied by the resonant inelastic x-ray scattering method. Anisotropic spectra in the ab-plane are observed in a twin-free crystal. The excitation from the one-dimensional CuO chain is enhanced at 2 eV near the zone boundary of the b* direction, while the excitation from the CuO2 plane is broad at 1.5-4 eV and almost independent of the momentum transfer. Theoretical calculation based on the one-dimensional and two-dimensional Hubbard model reproduces the observed spectra by taking the different parameters of the on-site Coulomb energy. The fact of the Mott gap of the CuO chain site is much smaller than that of CuO2 plane site is observed for the first time.

description: The COVID-19 pandemic has reshaped the demand for goods and services worldwide. The combination of a public health emergency, economic distress, and misinformation-driven panic have pushed customers and vendors towards the shadow economy. In particular, dark web marketplaces (DWMs), commercial websites accessible via free software, have gained significant popularity. Here, we analyse 851,199 listings extracted from 30 DWMs between January 1, 2020 and November 16, 2020. We identify 788 listings directly related to COVID-19 products and monitor the temporal evolution of product categories including Personal Protective Equipment (PPE), medicines (e.g., hydroxyclorochine), and medical frauds. Finally, we compare trends in their temporal evolution with variations in public attention, as measured by Twitter posts and Wikipedia page visits. We reveal how the online shadow economy has evolved during the COVID-19 pandemic and highlight the importance of a continuous monitoring of DWMs, especially now that real vaccines are available and in short supply. We anticipate our analysis will be of interest both to researchers and public agencies focused on the protection of public health.

description: La crisi dell’economia americana ha forti ripercussioni non solo sui paesi europei, ma sul mondo intero; le difficoltà di altri importanti paesi, come il Giappone e l’Argentina, già gravi, sono diventate ancora più gravi per la crisi americana. I paesi del Terzo Mondo mostrano andamenti molto differenziati: nei mercati in cui la presenza dell’America e di altri paesi industrializzati è indebolita dalla crisi, essi riescono a crescere anche più di prima, grazie soprattutto alle esportazioni dei beni di industrie tradizionali: per produrre tali beni usano tecniche che comportano un minor grado di meccanizzazione e una maggiore quota di lavoro diretto, e ciò consente una più ampia flessibilità dei prezzi, con la conseguenza che nei mercati internazionali la loro competitività migliora, specialmente in periodi di congiuntura negativa. Stimolati anche da una tale congiuntura vari paesi del Terzo Mondo stanno esercitando una pressione crescente per indurre i paesi industrializzati a eliminare gradualmente le protezioni – dazi e sussidi – erette a difesa delle loro agricolture; la via da seguire, però, non è questa: è la via degli aiuti organizzativi. The crisis in the U.S. economy has a major impact not only on Europe but the whole world; the difficulties of other major countries, such as Japan and Argentina, already serious, have become even more serious for the American crisis. The Third World countries show very different trends: in the markets in which the presence of America and other industrialized countries has been weakened by the crisis, they are able to grow even more than before, thanks to exports of goods of traditional industries: to produce these assets using techniques involving a lesser degree of mechanization and a greater proportion of direct business, which allows greater flexibility in prices, with the result that their competitiveness in international markets improves, especially in times of economic downturn. Stimulated also by such a situation many Third World countries are putting increasing pressure to induce the industrialized countries to phase out protection - tariffs and subsidies - erected in defense of their agriculture; the way forward, however, is this: the way of organizational aids.

description: The thermal relic density of the neutralino dark matter in the brane world cosmology is studied. Since the expansion law at a high energy regime in the brane world cosmology is modified from the one in the standard cosmology, the resultant relic density can be altered. It has been found that, if the five dimensional Planck mass $M_5$ is lower than $10^4$ TeV, the brane world cosmological effect is significant at the decoupling time and the resultant relic density is enhanced. We calculate the neutralino relic density in the Constrained Minimal Supersymmetric Standard Model (CMSSM) and show that the allowed region is dramatically modified from the one in the standard cosmology and eventually disappears as $M_5$ is decreasing. We also find a new lower bound on $M_5 \gtrsim 600$ TeV based on the neutralino dark matter hypothesis, namely the lower bound in order for the allowed region of the neutralino dark matter to exist.

description: A study was conducted over two cropping seasons to evaluate the production of culinary herbs planted in rotation with legume green manure crops: cowpea (Vigna unguiculata), hyacinth bean (Lablab purpureus) and sunnhemp (Crotolaria juncea). Green manure crops were established in replicated plots in the summer of 1996 and 1997. In each year, the green manure crops were mowed in October and plots were disk-plowed to incorporate green manure residues into the soil. Two months later, plots were prepared for planting of culinary herbs including chive (Allium schoenoprasum), basil (Ocimum basilicum), parsley (Petroselmum sativum), sage (Salvia officinalis), and cilantro {Coriandum sativum). Each plot consisted of three rows, 4 m long. The trial used a randomized complete block design with three replications. Results in general showed that although there were no significant differences in plant fresh and dry matter yield, herbs grown in rotation with sunnhemp and hyacinth bean tended to produce higher yields than those grown with cowpea or fallow rotations. Basil and cilantro grown after sunnhemp and hyacinth bean produced taller plants than those grown after cowpea and fallow. Sage was benefitted by sunnhemp in terms of increased plant fresh and dry matter yield. The benefit of green manure rotations on growth and yield of parsley and chive was about the same. These results suggest that without chemical fertilizers, legume green manure crops, particularly sunnhemp and hyacinth bean, can increase yield of culinary herbs in a crop rotation system

Sprayed glass fiber reinforced polymers in shear strengthening and enhancement of impact resistance of reinforced concrete beams

description: Shear failure of reinforced concrete (RC) beams is often sudden and catastrophic. A timely shear strengthening of deficient RC beams is therefore critical in view of maintaining public safety. In this dissertation, the effectiveness of externally bonded sprayed glass fiber reinforced polymer (Sprayed GFRP) in shear strengthening of RC beams under both quasi-static and impact loading was investigated. Direct comparisons were drawn with hand-applied, site-impregnated FRP fabric. To study RC beams under impact loads, a unique test setup was developed. In this setup, both the striking hammer and the specimen supports are instrumented and accelerometers are mounted on the specimen to accurately measure specimen inertial loads and to provide a proper dynamic analysis of the system. A total of 77 RC specimens were tested with and without FRP strengthening. Given that bond between FRP and concrete is the critical link, in the shear strengthening program, different techniques were used to enhance the bond between concrete and Sprayed GFRP. It was found that roughening the concrete surface using a pneumatic chisel and using mechanical fasteners were the most effective techniques. Also, Sprayed GFRP applied on 3 sides (U-shaped) was more effective than 2-sided Sprayed GFRP in shear strengthening under both static and impact loading. GFRP, both sprayed and fabric, increased the shear load carrying capacity of RC beams and their energy absorption capacities, but Sprayed GFRP, especially U-shaped, was more effective than fabric GFRP. An increase of up to 105% in load carrying capacity of strengthened RC beams was observed under impact loading with respect to un-strengthened RC beams. Simple equations were proposed to calculate the contribution of Sprayed GFRP in shear capacity of RC beams under quasi-static and impact loadings. Analysis of data indicated that the load carrying capacity of strengthened RC beams both under quasi-static and impact conditions was governed by the effective strain capacity of the Sprayed GFRP, which was, in turn, governed by the GFRP configuration and its bond with concrete. Future research should therefore focus on enhancing the strain capacity of the FRP when used as externally bonded reinforcement for structural strengthening.

description: "field potential of selected hot pepper (Capsicum chinense) cultivars were evaluated in three field experiments conducted from November 1997 to September 1998 in the Virgin Islands. The first experiment was conducted at the Agricultural Experiment Station (AES) and two trials were established (on-farm) in grower's fields. Five cultivars were evaluated at AES and both on-farm trials. Plants were spaced 0.60 m between plants within rows at all locations and 1.0 m between rows (AES) and 1.5 m (on-farm). Results of the AES trial indicated significant differences among cultivars for the measured parameters. 'West Indian Hot' produced the highest number (897,000) and fresh weight (7642 kg) of fruits per hectare in the AES trial which were both significantly higher than 'Red Scotch Bonnet' and 'Scotch Bonnet'. Additionally, 'Early Scotch Bonnet' also produced significantly more fruits (685,000 fruits/ha) than 'Scotch Bonnet'. 'Early Scotch Boimet' and 'Habanero' produced similar fruit yields. The higher yield from 'West Indian Hot' can be attributed to its longer duration of sustained production, reflecting a higher tolerance to viral infections, compared to the other cultivars. Results of the on-farm trials indicated that 'Yellow Scotch Bonnet' produced the highest number of fruits, but was not significantly different from 'Pink Scotch Bonnet'. Both cultivars produced fruit yields higher than 'Habanero'. 'Yellow Scotch Bonnet' was superior to the other cultivars in terms of fruit yield (16,973 kg/ha) significantly higher than the yield from all other cultivars. At the other farm location 'West Indies Red' was the most productive cultivar. The results of pungency analyses indicated that 'Chocolate Scotch Bonnet' produced the hottest peppers followed by Yellow and Pink Scotch Bonnets, and 'Habanero' from AES. 'West Indian Hot' was the mildest pepper. It appears that the Scotch Bonnet peppers are the most adapted and promising cultivars in the Virgin Islands. Additionally, 'West Indies Red' also has good potential for production in the Virgin Islands.
