description: Mobile Devices can be beneficial for older adults (OAs) if used effectively. Yet current research suggests a low level of take-up. We investigated the extent to which OAs use mobile devices to identify their likes, dislikes and expectations in order to find new ways to increase their interaction. We conducted a survey with 202 OAs (aged 50-86). Many OAs are using mobile phones for communication and information seeking technology. However, without asking a direct question, privacy concerns were raised as a potential barrier towards adoption. When designing mobile apps, privacy must be a primary consideration and built in feature.

description: The feasibility of implementing distinctive agriculture insurance in Hebei Province is analyzed from the following aspects covering the support of policies and laws; agricultural products and brands with Hebei distinct; the rich experience of insurance companies; farmers’ strong awareness on insurance and farmers’ great demand on agricultural insurance. The plights faced by distinctive agricultural insurance are pointed out. It includes weak awareness of farmers on buying insurance; low enthusiasm of insurance company; poor support from the government and backward laws and regulations and so on. The countermeasures on developing distinctive agricultural insurance are put forward. The countermeasures on improving farmers’ awareness on buying insurance; innovating the insurance products and services; increasing the support from the government; perfecting the legislation on agricultural insurance should be adopted to develop agricultural insurance.

description: Using the basin-hopping Monte Carlo minimization approach we report the global minima for aluminium, gold and platinum metal clusters modelled by the Voter-Chen version of the embedded-atom model potential containing up to 80 atoms. The virtue of the Voter-Chen potentials is that they are derived by fitting to experimental data of both diatomic molecules and bulk metals simultaneously. Therefore, it may be more appropriate for a wide range of the size of the clusters. This is important since almost all properties of the small clusters are size dependent. The results show that the global minima of the Al, Au and Pt clusters have structures based on either octahedral, decahedral, icosahedral or a mixture of decahedral and icosahedral packing. The 54-atom icosahedron without a central atom is found to be more stable than the 55-atom complete icosahedron for all of the elements considered in this work. The most of the Al global minima are identified as some fcc structures and many of the Au global minima are found to be some low symmetric structures, which are both in agreement with the previous experimental studies.

description: Taking Luochuan County of Shaanxi Province as an example ,the factors that affect farmers’ behaviors on participating in insurance is analyzed and evaluated according to the questionnaires and by selecting the indexes covering household features, agricultural production risks, the attitudes of rural households towards risks and the transaction cost of participating insurance and by using Logistic regression model. The results show that comparing with insurance company, the government has larger influence on farmers’ behaviors on participating insurance; the premium of agricultural insurance does not obstruct farmers’ participation in insurance; the bad-handled relations between the government and insurance company have bad effects on the development of local agricultural insurance. In order to promote farmers to participate in agricultural insurance, the relevant countermeasures are put forward: firstly, increasing the investment on rural education and improving cultural level of farmers; secondly, intensifying the promotion on agricultural insurance; thirdly, reasonably planning the duties and rights of the government and the insurance company; fourthly, vigorously encouraging the farmers to conduct scale production of apple and form the scale economy.

description: An initial set of interventions, including the closure of host and hostess clubs and voluntary limitation of non-household contact, likely greatly contributed to reducing the disease incidence of coronavirus disease (COVID-19) in Japan, but this approach must eventually be replaced by a more sustainable strategy. To characterize such a possible exit strategy from the restrictive guidelines, we quantified the next-generation matrix, accounting for high- and low-risk transmission settings. This matrix was used to project the future incidence in Tokyo and Osaka after the state of emergency is lifted, presenting multiple ‘post-emergency’ scenarios with different levels of restriction. The effective reproduction numbers (R) for the increasing phase, the transition phase and the state-of-emergency phase in the first wave of the disease were estimated as 1.78 (95% Credible Interval (CrI): 1.73–1.82), 0.74 (95% CrI: 0.71–0.78) and 0.63 (95% CrI: 0.61–0.65), respectively, in Tokyo and as 1.58 (95% CrI: 1.51–1.64), 1.20 (95% CrI: 1.15–1.25) and 0.48 (95% CrI: 0.44–0.51), respectively, in Osaka. Projections showed that a 50% decrease in the high-risk transmission is required to keep R

description: We show the existence of a noncommutative spacetime structure in the context of a complete discussion on the underlying spacetime symmetries for the physical system of a free massless relativistic particle. The above spacetime symmetry transformations are discussed for the first-order Lagrangian of the system where the transformations on the coordinates, velocities and momenta play very important roles. We discuss the dynamics of this system in a systematic manner by exploiting the symplectic structures associated with the four dimensional (non-)commutative cotangent (i.e. momentum phase) space corresponding to a two dimensional (non-)commutative configuration (i.e. target) space. A simple connection of the above noncommutativity (NC) is established with the NC associated with the subject of quantum groups where $SL_{q,q^{-1}} (2)$ transformations play a decisive role.

description: According to the data from Investigation Report of Land Use Change in China, The Land Resources Communique of China and Chronicle of Statistical Data for Five Decades of New China issued from Ministry of Land Resources, we select two indices: change of farmland quantity and policy of farmland protection. According to econometric theory, by using Eviewes 5.1 software, co-integration analysis, Granger causality test, impulse response and other analysis methods, we analyze the relationship between change of farmland quantity and policy of farmland protection in China since the reform and opening-up. The results show that there is long-term balanced relationship between change of farmland quantity and policy of farmland protection, and there is a certain mechanism restricting motion of variables between the two so as to make the two deviate from each other little and step towards balance in the long run; there is unilateral causality relationship between farmland change and policy of farmland protection, namely that the farmland change is the Granger cause of policy of farmland protection, while policy of farmland protection is not the Granger cause of farmland change; impulse response and variance decomposition indicate that farmland change plays the role of promoting policy of farmland protection continuously, and the role is strengthened along with prolonged lag period; the policy of farmland protection has strong inertia, because it is impacted by the former level of itself, and the policy of farmland protection plays insignificant role in promoting farmland quantity. Consequently, the important approach of solving problem of rapid decrease of farmland is to formulate long-term strategy, strengthen theoretical research of farmland protection and reinforce degree of formulation, implementation and surveillance of farmland protection policy.

description: On the basis of overview of the study area, by analyzing the dynamic change of farmland in Ninglang County, we can find that the farmland area in this county tended to decrease from 1996 to 2008. According to the investigation data concerning land change provided by Bureau of Land and Resources in Ninglang County and socio-economic data provided by Bureau of Statistics in Ninglang County, we select 11 indices, such as total population, GDP, total output value of county and so on, coupled with SPSS statistical method, we adopt principal component analysis method to analyze driving force factors of farmland use change in the high and cold areas in Northwest Yunnan. The results show that the two factors of economic development and population growth are the dominant driving factors impacting farmland use change, and the policy factors, such as “returning farmland to forests”, are also the important driving factors impacting Ninglang County.

description: By using the software SAS9.2 and the relevant data of consumption level of rural residents in China from 1952 to 2008, the ARIMA model is established. The model is used to analyze and forecast the time series of the consumption level of Chinese rural residents. The results show that in the near future period of time, the consumption level of Chinese rural residents will be further increased. In 2012, the level will break through per capital 5 000 yuan, almost 100 times more than that in the primary time period. But consumption level does not equal to living standard. To let farmers lead a good life, the government should follow the objective laws, take the overall situation into consideration; coordinate the relations among farmers’ consumption level, national subsidies and farmers’ production enthusiasm. Therefore, It suggested that the historical and objective factors should be attached more importance to，raising farmers’ income and allaying farmers’ fear were effective measures in developing the consumptive potential of rural market and promoting the economic sustainable development.

description: We study a protocol for two-qubit state guidance that does not rely on feedback mechanisms. In our scheme, entanglement can be concentrated by arranging the interactions of the qubits with a continuous variable ancilla. By properly post-selecting the outcomes of repeated measurements of the state of the ancilla, the qubit state is driven to have a desired amount of purity and entanglement. We stress the primary role played by the first iterations of the protocol. Inefficiencies in the detection operations can be fully taken into account.

description: We consider a nonlinear Dirichlet problem driven by a nonhomogeneous differential operator with a growth of order $(p-1)$ near $+\infty$ and with a reaction which has the competing effects of a parametric singular term and a $(p-1)$-superlinear perturbation which does not satisfy the usual Ambrosetti-Rabinowitz condition. Using variational tools, together with suitable truncation and strong comparison techniques, we prove a "bifurcation-type" theorem that describes the set of positive solutions as the parameter $λ$ moves on the positive semiaxis. We also show that for every $λ>0$, the problem has a smallest positive solution $u^*_λ$ and we demonstrate the monotonicity and continuity properties of the map $λ\mapsto u^*_λ$.

description: The fragmentation of the ground state of a repulsive condensate immersed into a double-trap potential is found to be a general and critical phenomenon. It takes place for a given number of bosons if their scattering length is larger than some critical value or for a given value of the scattering length if the number of bosons is above some critical number. We demonstrate that the geometry of the inner trap determines these critical parameters while the number of the fragments and the fraction of bosons in the various fragments can be manipulated by the outer trap. There is also a maximal number of bosons for which the ground state is fragmented. If this number is exceeded, the fragmented state becomes a very low-lying excited state of the condensate. This maximal number of bosons can be substantially manipulated by varying the inner and outer traps. To study three-fold fragmentation we have chosen a potential well with two barriers as the inner trap and embedded by two types of outer ones. A many-fold fragmentation is also addressed.

KIC 9406652: A laboratory of the tilted disk in cataclysmic variable stars

description: KIC 9406652 is a cataclysmic variable (CV), sub-classified as `IW And-type star', showing a repetition of standstills with oscillatory variations terminated by brightening. This system showed negative superhumps, semi-periodic variations having periods slightly shorter than the orbital period, and super-orbital signals, both of which are believed to originate from a precessing, tilted accretion disk. We have re-examined its Kepler light curve extending over 1500 d. In accordance with a cycle of the IW And-type light variation, the frequency of negative superhumps showed a reproducible variation: a rapid drop during the brightening and a gradual increase during the standstill. They are interpreted as the drastic change in the radial mass distribution and the expansion of the tilted disk, which is not expected from the existing models for IW And stars. The constancy in flux amplitudes of negative superhumps confirms that their light source is the bright spot sweeping across the surface of the tilted disk. The frequencies of negative superhumps and super-orbital signals varied in unison on long timescales, suggesting their common origin: the tilted disk. Orbital signals at the brightening were dominated by the irradiation of the secondary star and varied with the orientation of the tilted disk; the amplitude was maximized at the minimum of super-orbital signals and the light maximum shifted to early orbital phases as the super-orbital phase advances. This is the first direct evidence that the disk was tilted out of the binary orbital plane and retrogradely precessing. The tilt angle of the disk inferred from semi-amplitudes of super-orbital signals was lower than 3 degrees. The diversity in light curves of negative superhumps supports this and suggests that a part of the gas stream overflows the disk edge. This study thus offers rich information about the tilted disk in CVs.

description: The gap between urban and rural incomes in Guangxi is increasing year by year in a rising tendency, which resulted in agricultural development impact cannot be ignored. Such impact on agricultural development was analyzed from three aspects: agricultural development fund, farmland and food problems and labor force flow. The following problems were found: capitals flew to non-agricultural industry, which resulted in deficiency of agricultural development fund; farmland reduced and the problem of food supply is highlighted; labor force in rural areas emigrated, the price of agricultural products rose up. Related policies were offered: to strengthen the financial support; to speed up utilization of abundant labor force; to motivate farmers’ enthusiasm in food production; to increase investment in farmers’ endowment insurance and retirement pension in rural areas.
Analysis of undifferentiated human embryonic stem cell lines using Serial Analysis of Gene Expression

Publisher: name: University of British Columbia

description: Since the first reported isolation of immortalized human embryonic stem cell (hESC) lines in 1998 (Thomson et al., 1998), methods for directing their differentiation to various specialized derivatives has been extensively demonstrated and provides hope for future therapeutic applications. Characterization of the key molecular factors governing hESC self-renewal and pluripotency is necessary for ongoing efforts in deriving therapeutically useful cell types and in modelling human embryonic and oncogenic development. To this end the GSC Gene Expression Laboratory has generated 11 global gene expression profiles of 8 undifferentiated hESC lines using long Serial Analysis of Gene Expression (long SAGE) (NIH stem cell registry code BG01, ES03, ES04, WA01, WA07, WA09, WA13, and WA14). I analysed a database of the hESC long SAGE data consisting of 2,613,475 total tags corresponding to 379,465 transcripts. By employing various comprehensive tag-togene mapping resources I have provided a detailed survey of the genes expressed and differentially expressed in multiple hESC lines. A suite of sternness-associated factors was observed in the hESC SAGE data. We also observed molecular components of several pathways involved in embryonic development, the cell cycle, and programmed cell death. Comprehensive interspecies pair-wise comparisons between the hESC libraries and publicly available human SAGE libraries identified up-regulated transcripts in embryonic stem cells. A robust computational approach was designed and identified tags expressed solely in hESCs compared to 247 normal and malignant cells. A key feature of the approach was to isolate tags derived from sequences conserved across the human, mouse and rat genomes; this led to the identification of 301 candidate novel transcripts that may be integral to human pluripotent stem cells. These studies represent an important step in the development of high throughput approaches to an analysis of early human developmental processes and will be a strategic element in more comprehensive interspecies comparisons of E S cells to identify preserved control mechanisms.

description: The general perturbative expression for the lateral Casimir force between two plates covered by longitudinal corrugations of arbitrary shape is obtained. This expression is applicable for corrugation periods larger than the separation distance. The cases of asymmetric corrugations are considered, which allow to increase the maximum to minimum force ratio and affect the character of equilibrium points. This opens new opportunities to control the lateral Casimir forces for use in microelectromechanical devices based entirely on the vacuum fluctuation properties.

description: Negatively and positively charged excitons are identified in the spatially-resolved photoluminescence spectra of quantum wires. We demonstrate that charged excitons are weakly localized in disordered quantum wires. As a consequence, the enhancement of the "binding energy" of a charged exciton is caused, for a significant part, by the recoil energy transferred to the remaining charged carrier during its radiative recombination. We discover that the Coulomb correlation energy is not the sole origin of the "binding energy", in contrast to charged excitons confined in quantum dots.

The Hasegawa-Kishino-Yano model was used. A discrete Gamma distribution was used to model evolutionary rate differences among sites (5 categories (+G, parameter=0.4640)). The rate variation model allowed for some sites to be evolutionarily invariable ([+I], 66.25% sites). The tree with the highest log likelihood (-7560.65) is shown. The analysis involved 591 nucleotide sequences. There was a total of 1579 positions in the final dataset. Sequences generated in this study are shown in bold, with red for An. gambiae s.s., maroon for An. coluzzii and blue for An. melas sequences. Hybrid samples are shown with triangle node markers, whereas non-hybrids are shown with circles. Wolbachia negative (W-) specimens are shown with hollow node markers, whereas Wolbachia positives (W+) are denoted with filled node markers. Accession numbers are shown for sequences obtained from GenBank for comparison, except where duplicate identical sequences were replaced with a single representative, or where subtrees are compressed, for better visualisation. One representative sequence is shown for identical duplicate sequences from the same species, labelled with the species and number of duplicate sequences in brackets, with a diamond node marker. Appropriate subtrees are compressed, labelled with the species included and the number of sequences from each respective species shown in brackets. The tree is drawn to scale, with branch lengths measured in the number of substitutions per site. In c, square brackets denote the grouping of the Western Africa An. melas populations, where sequences generated in this study are also situated, with the Southern Africa and Equatorial Guinea (Bioko Island) populations clustering separately as previously found.

description: We report an efficient green one-pot approach for the synthesis of eighteen novel dihydro-4H-benzo[g]chromene derivatives under ultrasound irradiation conditions. The three-component condensation reaction proceeded through Knoevenagel-Michael reaction of chosen active methylene compounds and 2-hydroxynaphthalene-1,4-dione with different substituted aldehydes in the presence of ammonium acetate in water and ethanol mixture at room temperature, which furnished high yields of products (91–98%) in a rapid reaction time of 5–15 min. This procedure offers 95% of the atom economy and 100% of carbon efficiency together with other eco-friendly benefits.

description: The angle between the stellar spin-axis and the orbital plane of a stellar or planetary companion has important implications for the formation and evolution of such systems. A study by Hale (1994) found that binaries with separations $a < 30$ au are preferentially aligned while binaries on wider orbits are frequently misaligned. We aim to test the robustness of the Hale (1994) results by reanalysing the sample of visual binaries with measured rotation periods using independently derived stellar parameters and a Bayesian formalism. Our analysis is based on a combination of data from Hale (1994) and newly obtained spectroscopic data from the Hertzsprung SONG telescope, combined with astrometric data from Gaia DR2 and the Washington Double Star Catalog. We combine measurements of stellar radii and rotation periods to obtain stellar rotational velocities $v$. Rotational velocities $v$ are combined with measurements of projected rotational velocities $v\sin i$ to derive posterior probability distributions of stellar inclination angles $i$. We determine line-of-sight projected spin-orbit angles by comparing stellar inclination angles with astrometric orbital inclination angles. We find that the precision of the available data is insufficient to make inferences about the spin-orbit alignment of visual binaries. The data are equally compatible with alignment and misalignment at all orbital separations. We conclude that the previously reported trend that binaries with separations $a < 30$ au are preferentially aligned is spurious. The spin-orbit alignment distribution of visual binaries is unconstrained. Based on simulated observations, we predict that it will be difficult to reach the sufficient precision in $v\sin i$, rotation periods, and orbital inclination required to make robust statistical inferences about the spin-orbit alignment of visual binaries.

description: Probiotic foods, including fermented dairy (FD) products such as yogurt and cheese, naturally contain live microorganisms, but the relationship between the consumption of probiotic foods and health is unclear. The aim of the present narrative review is to integrate the available information on the relationship between the most studied FD products, which are yogurt and cheese, and cardiometabolic risk factors obtained from meta-analysis, systematic reviews of prospective cohort studies (PCSs) and PCSs published up to 2 November 2019. Additionally, the effects identified by randomized controlled trials of less-studied FD products, such as kefir and kimchi, on cardiometabolic risk factors are provided. PCSs have shown that the consumption of cheese, despite its high saturated fat content, is not associated with expected hypercholesterolemia and an increased cardiovascular risk. PCSs have revealed that the total consumption of FD appears to be associated with a lower risk of developing stroke and cardiovascular disease. The consumption of yogurt seems to be associated with a lower risk of developing type 2 diabetes. There is a lack of sufficient evidence of a protective relationship between FD or cheese consumption and metabolic syndrome. Moreover, the association of FD, cheese and yogurt with hypertension needs further evidence. In conclusion, the intake of fermented foods containing probiotics, particularly yogurt and cheese (of an undetermined type), opens up new opportunities for the management of cardiometabolic risk factors.

description: qRT PCR data for Wolbachia-infected individuals. RNA extracts were added to QubitTM RNA High Sensitivity Assays (Invitrogen) and total RNA was measured using a Qubit Flourometer (Invitrogen). All RNA extracts were then diluted to produce extracts that were 2.0 nanograms (ng)/ μL prior to being used in qRT PCR) assays targeting the 16S rRNA gene. A synthetic oligonucleotide standard (Integrated DNA Technologies) was designed to calculate 16S rRNA gene copies per μL using a serial dilution series.

description: According to the relevant data of China Statistical Yearbook and Chinese Rural Statistical Yearbook in the year of 2009, the changes of grey correlation degree of farmers’ net income, various items of incomes, national gross agriculture-supporting expenditure and various items of expenditures, farmers’ net income and various items of fiscal agriculture-supporting expenditure in the eighth Five-Year Plan, ninth Five-Year Plan and tenth Five-Year Plan by using grey correlation degree and the by choosing seven indicators covering income from wage and salary, income from household business, transfer income and property income, agricultural production-supporting expenditure, agricultural basic construction expenditure，expenses of three items of agricultural technology and the fee of rural relief. The results show that the grey correlation degree of each time period and household net income shows the downward trend; from overall perspective, the grey correlation degree of national gross agriculture-supporting expenditure, agricultural basic construction expenditure and agricultural production-supporting expenditure shows the descending trend; the grey correlation degree of fiscal agricultural supporting expenditure and the expenditure of three items of agricultural technology and fee of rural relief show the upward trend; the influence of agricultural production-supporting expenditure on farmers’ income shows downward trend; the influence of agricultural basic construction on farmers’ income shows upward trend; the fee of rural relief plays an active role in the promoting the farmers’ income increase; the role played by fee of rural relief in promoting farmers’ income increase should be further increased; the increase of farmers’ income shows great reliance on agricultural science and technology. In the end, the relevant suggestions on establishing stable increase mechanism of fiscal agricultural support and insisting on the dynamic adjustment of the structure of fiscal agricultural supporting capital are put forward.

description: We investigate the effect of magnetic fields on a Kondo insulator by using the periodic Anderson model. The analysis by dynamical mean field theory combined with quantum Monte Carlo simulations reveals that the magnetic field drives the Kondo insulator to a transverse antiferromagnetic insulator at low temperatures. We calculate the staggered spin susceptibility and find its divergence signaling the antiferromagnetic instability. Further investigation of the spin correlation functions and the magnetization process clarifies how the magnetic field suppresses the Kondo singlet formation and induces the transverse antiferromagnetic ordering.

Social cleavage and the party pie : the relationships between social heterogeneity and party systems in Canadian provinces
Creators: name: Tanaka, Kashi

description: One of the purposes of political parties is to reduce a heterogeneous polity into a few political elements. This thesis determines if there is a relationship between political parties and social cleavages in Canada. I have used provincial election results and census data from 1956 to 1991. Electoral results are converted into two measures of party system size, the effective number of parties (the number of significant parties in a legislature) and the competitive number of parties (the number of relevant parties in an election). Social heterogeneity is measured by converting census data into a series of indexes that measure the ethnic, religious, and linguistic diversity. 1 also examine the affect of rural/urban and centre periphery cleavages in provincial politics. I have found that there is a significant relationship between social heterogeneity and party system size in Canada. Of the cleavage structure examined, ethnicity is positively correlated with party system size and the size of a province's rural population is negatively correlated with party system size. Curiously, religion and language have mixed affects; religion is positively correlated with the number of parties that get elected but negatively correlated with the number of parties that win seats. Similarly, the size of a provinces French speaking population has a positive relationship with the number of parties that win seats but a negative relationship with the vote distribution among parties. There are two important conclusions in this thesis. First, there is substantial evidence that social heterogeneity influences party systems size in Canadian provinces. This result challenges institutional explanations which suggest that party systems in polities that use plurality electoral systems which elect single members will not be affected by social diversity. My second conclusion is the identification of a largely untouched area of research on provincial party systems. European theorists have used social structural approaches for fifty years to explain how societies and political parties co-evolve. This thesis proves that this approach has an important role to play on this side of the Atlantic.
