description: The coherent coupling between a quartz electro-mechanical resonator at room temperature and trapped ions in a 7-tesla Penning trap has been demonstrated for the first time. The signals arising from the coupling remain for integration times in the orders of seconds. From the measurements carried out, we demonstrate that the coupling allows detecting the reduced-cyclotron frequency ($ν_+$) within times below 10~ms and with an improved resolution compared to conventional electronic detection schemes. A resolving power $ν_+/Δν_+=2.4\times10^{7}$ has been reached in single measurements. In this publication we present the first results, emphasizing the novel features of the quartz resonator as fast non-destructive ion-trap detector together with different ways to analyze the data and considering aspects like precision, resolution and sensitivity.

description: Thermoelectric materials can recover electrical energy from waste heat and vice versa, which are of great significance in green energy harvesting and solid state refrigerator. The thermoelectric figure of merit (zT) quantifies the energy conversion efficiency, and a large Seebeck or Nernst effect is crucial for the development of thermoelectric devices. Here we present a significantly large Nernst thermopower in topological semimetal ZrTe5, which is attributed to both strong Berry curvature and bipolar transport. The largest in-plane S_xy (when B//b) approaches 1900 μV/K at T=100K and B=13T, and the out-of-plane S_xz (when B//c) reaches 5000 μV/K. As a critical part of z_N T, the linearly increased in-plane S_xy and resistivity \r{ho}_yy regard to B induces an almost linear increasing transversal z_N T without saturate under high fields. The maximum z_N T of 0.12 was obtained at B=13 T and T= 120K, which significantly surmounts its longitudinal counterpart under the same condition.

description: In recent years, graphene-like boron carbide and carbon nitride nanosheets have attracted remarkable attentions, owing to their semiconducting electronic nature and outstanding mechanical and heat transport properties. Graphene-like BC6N is an experimentally realized layered material and most recently has been the focus of numerous theoretical studies. Interestingly, the most stable form of BC6N monolayer remains unexplored and limited information are known concerning its intrinsic physical properties. Herein, on the basis of density functional theory (DFT) calculations we confirm that the most stable form of BC6N nanosheet shows a rectangular unitcell, in accordance with an overlooked experimental finding. We found that BC6N monolayer is a semiconductor with 1.19 eV direct gap and yields anisotropic and excellent absorption of visible light. First-principles results highlight that BC6N nanosheet exhibits anisotropic and ultrahigh tensile strength and lattice thermal conductivity, outperforming all other fabricated 2D semiconductors. We moreover develop classical molecular dynamic models for the evaluation of heat transport and mechanical properties of BC6N nanomembranes. The presented results in this work not only shed light on the most stable configuration of BC6N nanosheet, but also confirm its outstandingly appealing electronic, optical, heat conduction and mechanical properties, extremely motivating for further theoretical and experimental endeavors.

description: Using spinning we analyze in a geometric way Haefliger's smoothly knotted (4k-1)-spheres in the 6k-sphere. Consider the 2-torus standardly embedded in the 3-sphere, which is further standardly embedded in the 6-sphere. At each point of the 2-torus we have the normal disk pair: a 4-dimensional disk and a 1-dimensional proper sub-disk. We consider an isotopy (deformation) of the normal 1-disk inside the normal 4-disk, by using a map from the 2-torus to the space of long knots in 4-space, first considered by Budney. We use this isotopy in a construction called spinning about a submanifold introduced by the first-named author. Our main observation is that the resultant spun knot provides a generator of the Haefliger knot group of knotted 3-spheres in the 6-sphere. Our argument uses an explicit construction of a Seifert surface for the spun knot and works also for higher-dimensional Haefliger knots.

description: The study compares the value chains of virgin coconut oil (VCO) in Quezon and Laguna. Respondents include 18 VCO processors, 44 coconut farmers, 5 coconut assembler-wholesalers, 1 VCO assembler-wholesaler, and 8 VCO retailers. Descriptive, profitability, value addition, and marketing efficiency analyses were done. The most efficient marketing channel was found in Quezon and this involved farmers and assembler -wholesalers of coconut, large-scale processor-cum-wholesaler-retailers of VCO who used the fresh-wet-cold-pressed-absolute-no-heat-disc-centrifuge separation method, and VCO consumers. The problems and constraints in the value chain were unstable prices of fresh and matured coconut, insufficient supply of coconut for VCO processing, low or varied quality of VCO, and difficulty in complying with the requirements of the Food and Drug Administration and Philippine National Standards for VCO. The study recommends adoption of productivity measures in coconut production, market arrangements between farmers and coconut buyers, use of fresh-wet-cold-pressed-absolute-no-heat-disccentrifuge separation method in VCO processing, technical assistance to help processors comply with FDA and PNS requirements, and formation of a VCO cooperative in Laguna.

description: Ab initio molecular dynamics including non-adiabatic and spin-orbit couplings on equal footing is used to unravel the deactivation of cytosine after UV light absorption. Intersystem crossing (ISC) is found to compete directly with internal conversion in tens of femtoseconds, thus making cytosine the organic compound with the fastest triplet population calculated so far. It is found that close degeneracy between singlet and triplet states can more than compensate for very small spin-orbit couplings, leading to efficient ISC. The femtosecond nature of the intersystem crossing process highlights its importance in photochemistry and challenges the conventional view that large singlet-triplet couplings are required for an efficient population flow into triplet states. These findings are important to understand DNA photostability and the photochemistry and dynamics of organic molecules in general.

description: The study uses a Vector Error Correction model to show that a long run relationship/ causality exists between NFA stocks and world price and domestic retail price of rice in the Philippines. No short run relationship was found for NFA stocks and retail price while a short run relationship exists for world price and retail price. This implies that while NFA stocks can affect retail prices, a significant amount of time may occur before its effects are transmitted. An Autoregressive Distributed Lag-Error Correction model was also utilized. Results establish a strong short-run relationship between retail prices, total stocks, and world prices. Policywise, this result points to the importance of total supply management implying the need for proper timing in the purchase and release of NFA stocks for it to be effective in stabilizing prices

description: Heisenberg's uncertainty principle tells us that it is impossible to determine simultaneously the position of a photon crossing a telescope's aperture and its momentum. Super-resolution imaging techniques rely on modification of the observed sample, or on entangling photons. In astronomy we have no access to the object, but resolution may be improved by optical amplification. Unfortunately, spontaneous emission contributes noise and negates the possible gain from stimulated emissions. We show that it is possible to increase the weight of the stimulated photons by considering photon statistics, and observe an improvement in resolution. Most importantly, we demonstrate a method which can apply for all imaging purposes.

The development of a technique for the determination of disolved chromium(III) and total dissolved chromium in seawater by electron capture detection gas chromatography
Creators: name: Mugo, Robert K.
Publisher: name: University of British Columbia
Year: 2010

description: A gas chromatographic method for the determination of dissolved Cr(III) and total dissolved Cr in seawater was developed. The technique uses the electron capture detection of the 1,1,1-trifluoro-2,4-pentanedione (Htfa) derivative of Cr(III), Cr(tfa)₃, which was prepared from solvent extraction of a 15-mL seawater sample. The method was applied to stored acidified samples for the determination of total Cr and to stored, frozen, unacidified samples for the determination of Cr(III) and, after reduction, total Cr (with Cr(VI) being obtained as the difference of these two). The accuracy of the technique was assessed by the analysis of standard reference materials from the National Research Council of Canada. The Cr values obtained for the reference materials using this method were in good agreement with the certified values. The technique has a precision of 1.3% at 4.67 nM with detection limits (3 σn-₁) for Cr(III) and total Cr of 0.186 and 0.243 nM in the original seawater, respectively. The method is designed to be applied to the determination of Cr in seawater samples immediately after collection onboard ship during oceanographic cruises. The attempt to extend the technique to the determination of gallium in seawater was not successful due to thermal instability and/or insufficient volatility of the Ga(tfa)₃ chelate.

description: A longstanding issue in the study of quantum chromodynamics (QCD) is its behavior at nonzero baryon density, which has implications for many areas of physics. The path integral has a complex integrand when the quark chemical potential is nonzero and therefore has a sign problem, but it also has a generalized $\mathcal PT$ symmetry. We review some new approaches to $\mathcal PT$-symmetric field theories, including both analytical techniques and methods for lattice simulation. We show that $\mathcal PT$-symmetric field theories with more than one field generally have a much richer phase structure than their Hermitian counterparts, including stable phases with patterning behavior. The case of a $\mathcal PT$-symmetric extension of a $ϕ^4$ model is explained in detail. The relevance of these results to finite density QCD is explained, and we show that a simple model of finite density QCD exhibits a patterned phase in its critical region.

description: Reliably distinguishing between cells based on minute differences in receptor density is crucial for cell-cell or virus-cell recognition, the initiation of signal transduction and selective targeting in directed drug delivery. Such sharp differentiation between different surfaces based on their receptor density can only be achieved by multivalent interactions. Several theoretical and experimental works have contributed to our understanding of this "superselectivity", however a versatile, controlled experimental model system that allows quantitative measurements on the ligand-receptor level is still missing. Here, we present a multivalent model system based on colloidal particles equipped with surface-mobile DNA linkers that can superselectively target a surface functionalized with the complementary mobile DNA-linkers. Using a combined approach of light microscopy and Foerster Resonance Energy Transfer (FRET), we can directly observe the binding and recruitment of the ligand-receptor pairs in the contact area. We find a non-linear transition in colloid-surface binding probability with increasing ligand or receptor concentration. In addition, we observe an increased sensitivity with weaker ligand-receptor interactions and we confirm that the time-scale of binding reversibility of individual linkers has a strong influence on superselectivity. These unprecedented insights on the ligand-receptor level provide new, dynamic information into the multivalent interaction between two fluidic membranes mediated by both mobile receptors and ligands and will enable future work on the role of spatial-temporal ligand-receptor dynamics on colloid-surface binding.

description: The Philippine Competition Act promotes free and fair market competition to improve market efficiency and protect consumer welfare. Thus, it is necessary to examine and assess the nature of competition in any industry. This was done by conducting the study of broiler, chicken egg, and swine industries using the market structure-conductperformance approach. The degree of firm concentration, barriers to entry, profitability of production, return on investment, and share in every peso spent by the consumers were determined. Based on the analysis, markets for chicken egg and pork were fairly competitive while that of chicken meat was oligopolistic. Huge capital investment also showed to be a hindrance for greater competition in all the industries. Large share in consumer’s peso was more likely an issue in the chicken meat market than in chicken egg and swine. Monitoring the behavior of large firms, reducing structural barriers, and increasing production efficiencies are necessary to improve markets of these industries thus ensuring a vibrant competition.

description: Completely natural electroweak symmetry breaking is easily achieved in supersymmetric models if there is a SM-like Higgs boson, $h$, with $m_h\lsim 100\gev$. In the minimal supersymmetric model, such an $h$ decays mainly to $b\anti b$ and is ruled out by LEP constraints. However, if the MSSM Higgs sector is expanded so that $h$ decays mainly to still lighter Higgs bosons, e.g. $h\to aa$, with $BR(h\to aa)>0.7$, and if $m_a<2m_b$, then the LEP constraints are satisfied. In this letter, we show that in the next-to-minimal supersymmetric model the above $h$ and $a$ properties (for the lightest CP-even and CP-odd Higgs bosons, respectively) imply a lower bound on $BR(Υ\to \gam a)$ that dedicated runs at present (and future) $B$ factories can explore.

description: Abstract: An induced-transmission filter (ITF) uses an ultrathin layer of metal positioned at an electric-field node within a dielectric thin-film bandpass filter to select one transmission band while suppressing other transmission bands that would have been present without the metal layer. Here, we introduce a switchable mid-infrared ITF where the metal film can be "switched on and off", enabling the modulation of the filter response from single-band to multiband. The switching is enabled by a deeply subwavelength film of vanadium dioxide (VO2), which undergoes a reversible insulator-to-metal phase transition. We designed and experimentally demonstrated an ITF that can switch between two states: one broad passband across the long-wave infrared (LWIR, 8 - 12 um) and one narrow passband at ~8.8 um. Our work generalizes the ITF -- previously a niche type of bandpass filter -- into a new class of tunable devices. Furthermore, our unique fabrication process -- which begins with thin-film VO2 on a suspended membrane -- enables the integration of VO2 into any thin-film assembly that is compatible with physical vapor deposition (PVD) processes, and is thus a new platform for realizing tunable thin-film filters.

description: In this paper we study CP violation in photon self-interactions at low energy. These interactions, mediated by the effective operator $FFF\tilde{F}$, where ($\tilde F$) $F$ is the (dual) electromagnetic field strength, have yet to be directly probed experimentally. Possible sources for such interactions are weakly coupled light scalars with both scalar and pseudoscalar couplings to photons (for instance, complex Higgs-portal scalars or the relaxion), or new light fermions coupled to photons via dipole operators. We propose a method to isolate the CP-violating contribution to the photon self-interactions using Superconducting Radio-Frequency cavities and vacuum birefringence experiments. In addition, we consider several theoretical and experimental indirect bounds on the scale of new physics associated with the above effective operator, and present projections for the sensitivity of the proposed experiments to this scale. We also discuss the implications of these bounds on the CP-violating couplings of new light particles coupled to photons.

description: Tea production is considered the key sector in Thai Nguyen Province for its provision of livelihood to 40% of rural households. The province is also best known for its traditional green teas with a century history. Based on the primary data collected through field surveys and key informant interviews in Thai Nguyen city and Dai Tu district, the analysis of Thai Nguyen’s tea value chain was done by segments and key players. Thai Nguyen’s tea is mainly consumed domestically while tea in Vietnam in general is intended more for export. Results of the analysis showed significant differences in gaining profits among key players. In particular, tea growers with certified production earned more than those with non-certified farming practices. Better profits were also concentrated in the group of Kinh farmers and tea growers in Thai Nguyen City or in tea growing households with higher education levels and with production and/or market linkages. Lower profits from exports of tea materials and the decrease in export volumes in recent years would imply weak competitiveness of Thai Nguyen’s tea exports, which was mainly attributed to nonstandardized farming practices, small-scale production and non-rigorous control of food hygiene and safety. In order to improve the tea value chain in the international market, it is necessary to develop a quality-focused strategy for tea products in Thai-Nguyen province, improve the social recognition of GAP-certified households producing tea and provide incentives for GAP-adoption and renewal of certification, increase investment in irrigation infrastructure, provide adequate R&D funding for the diversification of tea products and development of environment-friendly packaging materials, plan and establish a processing cluster for tea products, and coordinate and support enterprises to provide updated market information and trade promotion for tea products.

description: An assessment of levels of satisfaction was conducted among 142 faculty members of a Philippine university. In general, the members of the faculty were satisfied with their jobs. These were due to the personal and professional growth and development, as well as the freedom and flexibility the job has provided them to achieve work-life balance. Though, administrative functions such as promotion, document processing, salary and benefits, and university facilities were evaluated to be relatively less satisfactory. Using regression analysis, it was determined that years of service, gender, number of course preparations, work fulfillment, safety, salary contentment, and career advancement significantly contribute to satisfaction. Further, utilizing factor analysis, six relevant factors related to job satisfaction were identified; workload, social and societal interactions, growth and development, compensation and benefits, administration, and classroom experience. Satisfaction was seen to have moderate and weak positive relationship with organizational citizenship and intent to continue work, respectively. It is recommended that the university should continue creating an environment conducive for personal and professional growth and development through its plans and programs. The insights the research provided call for more efficient document processing through automation and computerization, thorough review and revision of promotion policies and procedures, and improvements in infrastructure.

description: Many approaches, which have been developed to express the potential energy of large systems, exploit the locality of the atomic interactions. A prominent example are fragmentation methods, in which quantum chemical calculations are carried out for overlapping small fragments of a given molecule that are then combined in a second step to yield the system's total energy. Here we compare the accuracy of the systematic molecular fragmentation approach with the performance of high-dimensional neural network (HDNN) potentials introduced by Behler and Parrinello. HDNN potentials are similar in spirit to the fragmentation approach in that the total energy is constructed as a sum of environment-dependent atomic energies, which are derived indirectly from electronic structure calculations. As a benchmark set we use all-trans alkanes containing up to eleven carbon atoms at the coupled cluster level of theory. These molecules have been chosen because they allow to extrapolate reliable reference energies for very long chains, enabling an assessment of the energies obtained by both methods for alkanes including up to 10 000 carbon atoms. We find that both methods predict high-quality energies with the HDNN potentials yielding smaller errors with respect to the coupled cluster reference.

description: To verify the hypothesis about the common origin of the low frequency 1/f noise and the quantum f noise recently measured in the Josephson charge qubits, we study temperature dependence of the 1/f noise and decay of coherent oscillations. T^2 dependence of the 1/f noise is experimentally demonstrated, which supports the hypothesis. We also show that dephasing in the Josephson charge qubits off the electrostatic energy degeneracy point is consistently explained by the same low frequency 1/f noise that is observed in the transport measurements.

description: ProtoDUNE-DP is a 6x6x6 m3 liquid argon time-projection-chamber operated at the CERN Neutrino Platform in 2019-2020 as a prototype of the Dual Phase concept for the DUNE Far Detector. The Photon Detection System (PDS) is based on 36 8-inch photo-multiplier tubes (PMTs) and allows triggering on the scintillation light signals produced by cosmic rays and other charged particles traversing the detector. The acquisition and calibration software specifically developed for the ProtoDUNE-DP PDS is described in this paper. This software controls the high-voltage power supplies, the calibration system, and the PDS DAQ. It has been developed with Qt Creator, and features different operation modes, and a graphical user interface. This software has already been validated and used during the ProtoDUNE-DP operation.
Deoxy and deoxyfluoro glycosides as mechanistic probes of Escherichia coli (lacZ) B-galactosidase
Creators: name: McCarter, John D
Publisher: name: University of British Columbia
Year: 2010

description: The mechanism of galactoside hydrolysis by Escherichia coli (lacZ) β-galactosidase was probed with a series of 2',4' dinitrophenyl deoxy and deoxyfluoro glycopyranosides. A two-step mechanism has been proposed previously for this process: 1) cleavage of the glycosidic bond and formation of a covalent galactosyl-enzyme intermediate ("galactosylation"); 2) hydrolysis of the mtermediate to give free enzyme and galactose ("degalactyosylation"). A series of deoxy and deoxyfluoro analogs of 2',4'-dinitrophenyl-β,-D- galactopyranoside was prepared for this study. The 2-deoxyfluoro derivative was found to be an effective mechanism-based inactivator of E. coli (lacZ) β-galactosidase. This compound thus joins a class of 2-deoxy-2-fluoro glycosides which inactivate glycosidases of this type by the accumulation of a stable glycosyl-enzyme intermediate. The active site-directed nature of this inhibitor was shown by protection against inactivation by a competitive ligand and the near 1:1 stoichiometry of dinitrophenolate release with enzyme inactivation. Furthermore, when freed from excess inactivator the 2-deoxy-2-fluorogalactosyl enzyme intermediate turned over slowly in buffer (t₁⃓₂ = 69 h at 25°C) and exhibited enhanced rates of reactivation in the presence of the acceptors methanol or glucose, providing strong evidence that the intermediate is catalytically competent The other deoxy and deoxyfluoro analogs synthesized were substrates for the enzyme although the rates of enzymic hydrolysis were two to four orders of magnitude slower than have been measured for the parent compound. These large rate reductions are thought to result primarily from the loss of important transition state binding interactions due to the substitution of a hydrogen or a fluorine for a hydroxyl at a given position on the galactopyranose ring. These results strongly suggest that much of the catalytic power of the enzyme is derived from non-covalent interactions between the enzyme active site and the galactopyranose ring of the substrate. A linear free energy relationship (r = 0.80) was shown to exist between the logarithm of kcat/Km for the enzyme-catalyzed reaction and the logarithm of the first order rate constant for the spontaneous hydrolysis of the same series of deoxy and deoxyfluoro glycopyranosides. Since the spontaneous process has considerable oxocarbonium ion character at the transition state, these data suggest that the enzymic mechanism involves a similar electron deficient transition state.

description: The paper is an empirical study of the technical efficiency of yellow corn farmers in selected provinces of the Philippines using cross section data from 154 corn farmers. It aimed to determine the level of input utilization, profitability of yellow corn and determine the factors affecting corn productivity and technical efficiency. A Stochastic Frontier Production Function Model through maximum likelihood estimation (MLE) Method was used to estimate farm-level technical efficiency. Analysis showed that, on the average, yellow corn farmers used 91.7 kilogram of seeds; applied 224 kilograms of nitrogen, 49 kilograms of Phosphorous, 9 kilograms of Potassium; and applied PhP 3,039 worth of agro -chemicals in one production season. The results also showed that the average technical efficiency of yellow corn farmers was 67.6 percent. It was found that the amount of seeds, nitrogen and potassium fertilizers, and agro-chemicals used are significant factors influencing the productivity of yellow corn in the study areas. Moreover, factors such as the level of education of the farmers; years of farmers’ experience in yellow corn production; and training and seminars attended by the farmers showed positive effects on the farm-level technical efficiency of yellow corn farms.
Dual Interpretations of Pion Clouds at RHIC

description: A gauge theory of pions interacting with rho-mesons at elevated temperatures is used to calculate the pressure in a hot pion gas. No reference is made to the pion's status as a QCD Goldstone boson. The role of the pion is merely that of a carrier of an SU(2) symmetry, gauged to create a vector-meson interaction, the rho playing the role of the interacting vector particle. The results are in rough agreement with much more elaborate calculations, both of the purely hadronic variety, and those that invoke quark-gluon degrees of freedom. The quark-gluon and purely hadronic calculations seemingly lead to very similar predictions which are in accord with receent data from RHIC. The results motivate the question as to whether the two descriptions are dual to each other in the sense of being alternate models, each sufficient to explain the observed data.

Phase separation of active Brownian particles in two dimensions: Anything for a quiet life

description: Active Brownian particles display self-propelled movement, which can be modelled as arising from a one-body force. Although their interparticle interactions are purely repulsive, for strong self propulsion the swimmers phase separate into dilute and dense phases. We describe in detail a recent theory (Phys. Rev. E 100, 052604 (2019); Phys. Rev. Lett. 128, 26802 (2019)) for such motility induced phase-separation. Starting from the continuity equation and the force density balance, the description is based on four superadiabatic contributions to the internal force density. Here the superadiabatic forces are due to the flow in the system and they act on top of the adiabatic forces that arise from the equilibrium free energy. Phase coexistence is described by bulk state functions and agrees quantitatively with Brownian dynamics simulation results from the literature. We describe in detail all analytical steps to fully resolve the spatial and orientational dependence of the one-body density and current. The decomposition into angular Fourier series leads to coupling of total density, polarization and all higher modes. We describe the power functional approach, including the kinematic dependence of the superadiabatic force fields and the quiet life effect that pushes particles from fast to slow regions, and hence induces the phase separation.
