description: Here it is proposed a decomposition in components of the “waves” which appear in the time series of data related to Covid-19 pandemic. The decomposition is based on functions of κ-statistics; in particular the κ-Weibull is used. Fitted data are those of the “waves” ranging from August 2020 to April 2021 in the United Kingdom, from September 2020 to May 2021 in Ireland, and from September 2020 to June 2021 in Italy. For the United Kingdom, the time series of daily infection shows a wave composed by two peaks. Among the many factors involved in the spread of infection, it seems that, in driving the onset of the second peak, the main role was played by the emergence of Alpha variant of Sars-Cov-2. For what concerns data from Ireland, if we decompose the analysed “wave” in three components, we can observed that for one of them the role of the Alpha variant was relevant for sure. In the case of Italy, the effect is less evident, because it was spread over a larger time interval.

A comparison of methods for the isolation of deoxyribonucleic acid from small amounts of tissue
Creators: name: Mezei, Catherine
Publisher: name: University of British Columbia
Year: 2012

description: The chemical and physico - chemical properties of deoxyribonucleic acid preparations isolated from small amounts of liver and intestinal mucosa of rat (1-10 g.) by five different procedures, have been compared. The first method (29), used for preparation of deoxyribonucleic acid was based on the separation of nuclei from tissue homogenates, followed by extraction and deproteinization of deoxyribonucleic acid with strong salt solutions. The second method (20, 31) consisted of the extraction and deproteinization of nucleic acids by detergent solutions, and separation of ribonucleic acid and deoxyribonucleic acid by fractional precipitation with iso-propyl alcohol. In the third procedure crude deoxyribonucleic acid was isolated from nuclei according to the first method and the crude product was further purified according to the second procedure. The fourth method (32) was based on the disintegration of tissues by high frequency sonic oscillations, extraction of nucleoprotein from the nuclear fragments with strong salt solutions and deproteinization of deoxyribonucleic acid with chloroform -amyl alcohol mixtures. In the fifth method (36, 37) nucleic acids were extracted from tissues by hot, strong salt solutions, ribonucleic acid and deoxyribonucleic acid were separated by alkali treatment and deoxyribonucleic acid was precipitated with concentrated acid solutions. The advantages and shortcomings of the different procedures with respect to yield, purity and macromolecular state of the isolated material have been discussed. An improved technique has been described for the elution of purine and pyrimidine bases from paper chromatograms.

A Coup that failed? Recent Political Events in Vanuatu
Creators: name: Ambrose, David
Publisher: name: Canberra, ACT: Coral Bell School of Asia Pacific Affairs, College of Asia and the Pacific, The Australian National University
Year: 1996

description: When Vanuatu conducted its fourth postindependence general election, in November last year, more was at stake perhaps than in any previous election. For the first twelve years of independence, the country's anglophone majority had held government through the same party, the Vanua'aku Party (VP), and its constituents had enjoyed the benefits that power and the scope for preferment that being in office brings. For many anglophone politicians and constituents alike, therefore, the four years spent in Opposition, 1991-1995, were a painful lesson in the consequences of electoral defeat. By contrast, the francophone minority, who had endured more than a decade of, in their view, disadvantage and discrimination under anglophone rule, finally won office in 1991 and had begun to redress those years of perceived injustice and inequality

description: During the COVID-19 pandemic, countless individuals across the world needed novel and sophisticated health care resources simultaneously, leading to dramatic global shortages. How to distribute resources in such situations? This dilemma is neither new nor understudied: Its complexity is well known to medical ethicists, public health scientists and philosophers. Building on this knowledge, powerful global distribution frameworks were proposed already early into the pandemic. Despite this knowledge, no globally consensual regulations existed (and exist) on the political sphere. Worse still, numerous countries hoarded resources for themselves, increasing global inequalities and prolonging the pandemic for everyone. For future emergencies, it is thus necessary to develop immediately applicable strategies. Because public acceptance is key for such interventions, evidence on the public opinion towards allocation principles is strongly needed. In 2021, we asked representative samples of N = 2694 adults in England and Germany to rate seven COVID-19-specific global allocation principles. In line with literature on justice attitudes in general, extensions of bifactor(S-1) models showed that participants would have preferred a more equity- or equality-based global resource distribution during the pandemic, presenting themselves as more cosmopolitan than global leaders. Trying to understand these attitudes better, we tested preregistered hypotheses on relations with other constructs and found positive associations between equity- and equality-directed preferences and global human identification, among others. To ensure generalisability on future pandemics, we collected data from a second cohort in spring 2024. All results will be presented in detail. With their responses, European citizens call upon the development of fairer and more efficient global distribution mechanisms. This global public health perspective could inform preparations for future global emergencies.

Geometrical simplification of the dipole-dipole interaction formula

description: Many students meet quite early this dipole-dipole potential energy when they are taught electrostatics or magnetostatics, and it is also a very popular formula, featured in the encyclopedias. We show that by a simple rewriting of the formula it becomes apparent that for example, by reorienting the two dipoles, their attraction can become exactly twice as large. The physical facts are naturally known, but the presented transformation seems to underline the geometrical features in a rather unexpected way. The consequence of the discussed features is the so called magic angle which appears in many applications. The present discussion also contributes to an easier introduction of this feature. We also discuss a possibility for designing educational toys and try to suggest why this formula has not been written down frequently before this work. Similar transformation is possible for the field of a single dipole, there it seems to be observed earlier, but also in this case we could not find any published detailed discussion.

description: Let $G$ be a simple undirected graph on $n$ vertices. Francisco and Van Tuyl have shown that if $G$ is chordal, then $\bigcap_{\{x_i,x_j\}\in E_G} < x_i,x_j>$ is componentwise linear. A natural question that arises is for which $t_{ij}>1$ the ideal $\bigcap_{\{x_i,x_j\}\in E_G}< x_i, x_j>^{t_{ij}}$ is componentwise linear, if $G$ is chordal. In this report we show that $\bigcap_{\{x_i,x_j\}\in E_G} < x_i, x_j>^{t}$ is componentwise linear for all $n\geq 3$ and positive $t$, if $G$ is a complete graph. We give also an example where $G$ is chordal, but the intersection ideal is not componentwise linear for any $t>1$.

The diurnal migration of peamouth club Mylocheilus caurinus (Richardson) in Nicola Lake, British Columbia
Creators: name: MacLeod, John Cameron
Publisher: name: University of British Columbia
Year: 2012

description: Diurnal migration of adult peamouth chub was studied in Nicola lake. Results are taken from over two hundred gill net sets in 1959 during which time more than five thousand chub were netted. A migration surfaceward and shoreward occurred in evening and a reverse migration in morning. Diurnal migration was characteristic of the summer. Chub during winter had constant close association with the bottom at which time bottom organisms were the main food item. Onset of diurnal migration in summer was accompanied by increase in importance of plankton and chironomid pupae in the diet. Adults of all sizes and both sexes performed similar diurnal migrations but young-of-the-year chub showed the reverse migration, inhabiting shallow shore waters by day and dispersing to deep water by night. Inversion in behaviour occurred at about one year of age. Adult migration was unrelated to oxygen or temperature changes but timing of migration and depth distribution of chub was closely associated with light intensity, adults avoiding brightly illuminated areas. A diurnal change in diet accompanied the migration. In August food items changed from plankton during day to chironomid larvae and pupae in evening and night. Adaptive value of the migration is discussed in relation to physical and biotic characteristics of the environment.

Anomalous behavior of trapping on a fractal scale-free network

description: It is known that the heterogeneity of scale-free networks helps enhancing the efficiency of trapping processes performed on them. In this paper, we show that transport efficiency is much lower in a fractal scale-free network than in non-fractal networks. To this end, we examine a simple random walk with a fixed trap at a given position on a fractal scale-free network. We calculate analytically the mean first-passage time (MFPT) as a measure of the efficiency for the trapping process, and obtain a closed-form expression for MFPT, which agrees with direct numerical calculations. We find that, in the limit of a large network order $V$, the MFPT $$ behaves superlinearly as $ \sim V^{3/2}$ with an exponent 3/2 much larger than 1, which is in sharp contrast to the scaling $ \sim V^θ$ with $θ\leq 1$, previously obtained for non-fractal scale-free networks. Our results indicate that the degree distribution of scale-free networks is not sufficient to characterize trapping processes taking place on them. Since various real-world networks are simultaneously scale-free and fractal, our results may shed light on the understanding of trapping processes running on real-life systems.

description: A near-field scanning optical microscope is used to locally induce photocurrent in a graphene transistor with high spatial resolution. By analyzing the spatially resolved photo-response, we find that in the n-type conduction regime a p-n-p structure forms along the graphene device due to the doping of the graphene by the metal contacts. The modification of the electronic structure is not limited only underneath the metal electrodes, but extends 0.2-0.3 um into the graphene channel. The asymmetric conduction behavior of electrons and holes that is commonly observed in graphene transistors is discussed in light of the potential profiles obtained from this photocurrent imaging approach. Furthermore, we show that photocurrent imaging can be used to probe single- / multi-layer graphene interfaces.

description: One of the key problems in star formation research is to determine the role of magnetic fields. Starting from the atomic inter-cloud medium (ICM) which has density nH ~ 1 per cubic cm, gas must accumulate from a volume several hundred pc across in order to form a typical molecular cloud. Star formation usually occurs in cloud cores, which have linear sizes below 1 pc and densities nH2 > 10^5 per cubic cm. With current technologies, it is hard to probe magnetic fields at scales lying between the accumulation length and the size of cloud cores, a range corresponds to many levels of turbulent eddy cascade, and many orders of magnitude of density amplification. For field directions detected from the two extremes, however, we show here that a significant correlation is found. Comparing this result with molecular cloud simulations, only the sub-Alfvenic cases result in field orientations consistent with our observations.

Divergence of the logarithm of a unimodular monodromy matrix near the edges of the Brillouin zone

description: A first-order differential system with matrix of periodic coefficients $Q(y)=Q(y+T) $ is studied for time-harmonic elastic waves in a unidirectionally periodic medium, for which the monodromy matrix $M(ω) $ implies a propagator of the wave field over a period. The main interest in the matrix logarithm $\ln M(ω) $ is due to the fact that it yields the 'effective' matrix $Q_{eff}(ω) $ of the dynamic-homogenization method. For the typical case of a unimodular matrix $M(ω)$ ($\det M=1$), it is established that the components of $\ln M(ω) $ diverge as $(ω-ω_0)^{-1/2}$ with $ω\to ω_0,$ where $ω_0$ is the set of frequencies of the passband/stopband crossovers at the edges of the first Brillouin zone. The divergence disappears for a homogeneous medium. Mathematical and physical aspects of this observation are discussed. Explicit analytical examples of $Q_{eff}(ω) $ and of its diverging asymptotics at $ω\to ω_0$ are provided for a model of scalar waves in a two-component periodic structure. The case of high contrast due to stiff/soft layers or soft springs is elaborated. Special attention in this case is given to the asymptotics of $Q_{eff}(ω)$ near the first stopband that occurs at the Brillouin-zone edge at arbitrary low frequency. The link to the quasi-static asymptotics of the same $Q_{eff}(ω)$ near the point $ω=0$ is also elucidated.

description: We obtain the exact analytic form of the growth index at present epoch ($a=1$) in a flat universe with the cosmological constant ({\it i.e.} the dark energy with its equation of state $ω_{de} = -1$). For the cosmological constant, we obtain the exact value of the current growth index parameter $γ= 0.5547$, which is very close to the well known value 6/11. We also obtain the exact analytic solution of the growth factor for $ω_{de}$ = -1/3 or -1. We investigate the growth index and its parameter at any epoch with this exact solution. In addition to this, we are able to find the exact $Ω_{m}^{0}$ dependence of those observable quantities. The growth index is quite sensitive to $Ω_{m}^{0}$ at $z = 0.15$, where we are able to use 2dF observation. If we adopt 2dF value of growth index, then we obtain the constrain $0.11 \leq Ω_{m}^{0} \leq 0.37$ for the cosmological constant model. Especially, the growth index is quite sensitive to $Ω_{m}^{0}$ around $z \leq 1$. We might be able to obtain interesting observations around this epoch. Thus, the analytic solution for this growth factor provides the very useful tools for future observations to constrain the exact values of observational quantities at any epoch related to growth factor for $ω_{de} = -1$ or -1/3.

description: We present a time-dependent localized Hartree-Fock density-functional linear response approach for the treatment of photoionization of atomic systems. This approach employs a spin-dependent localized Hartree-Fock (SLHF) exchange potential to calculate electron orbitals and kernel functions, and thus can be used to study the photoionization from atomic excited states. We have applied the approach to the calculation of photoionization cross sections of Ne ground state. The results are in agreement with available experimental data and have comparable accuracies with other ab initio theoretical results. We have also extended the approach to explore the photoionization from Ne excited states and obtained some new results for the photoionization from outer-shell and inner-shell excited states.

description: Cannabis is widely used in the United States despite federal laws. In US states that have progressed toward legalization, there have been various reported impacts on cannabis-related emergency department (ED) visits. However, studies on the impact of legalization in Massachusetts (MA) EDs are lacking. Cannabinoid immunoassay (THC IA) results and cannabis-related ICD-10 codes were obtained for consecutive patient ED visits at two academic medical centers in Boston, MA over the following legalization periods (January 2012–December 2019): decriminalized (DEC), before medical dispensaries (MED BD), medical dispensaries available (MED DISP), before recreational dispensaries (REC BD) and recreational dispensaries available (REC DISP). Trends and monthly positivity rates for THC IA and ICD-10 codes were determined for these legalization periods. There was an increase in both THC IA (p < .0001) and cannabis-related ICD-10 codes (p < .0001) in the ED as legalization progressed at both institutions. Positivity rates significantly increased by 7% for THC IA and 0.4% for ICD-10 codes. Increases in THC IA positivity were seen in females, patients aged 30–39, older adults (>59 years), and those in the highest income tertile. There was an increasing trend in amphetamine positivity and decreasing trend in opiate positivity in patients with positive THC IA. Unlike THC IA, significant trends per patient demographics were not seen with ICD-10 codes. Legalization of marijuana in MA has led to an increase in cannabis use as indicated by both increasing rates of positive THC IA results, in older adults, as well as increasing cannabis-related ICD-10 codes. Data suggest a steady increase in THC use associated with legalization that was not associated with an increase in opiate, fentanyl, or cocaine use. We recommend using ED THC IA positivity, an objective laboratory measure, to monitor THC use and the impact of state-specific progression in cannabis legalization.
