description: The GALEX Arecibo SDSS Survey (GASS) is an ambitious program designed to investigate the cold gas properties of massive galaxies, a challenging population for HI studies. Using the Arecibo radio telescope, GASS is gathering high-quality HI-line spectra for an unbiased sample of ~1000 galaxies with stellar masses greater than 10^10 Msun and redshifts 0.025 < z < 0.05, uniformly selected from the SDSS spectroscopic and GALEX imaging surveys. The galaxies are observed until detected or until a low gas mass fraction limit (1.5-5%) is reached. We present initial results based on the first Data Release, which consists of ~20% of the final GASS sample. We use this data set to explore the main scaling relations of HI gas fraction with galaxy structure and NUV-r colour, and show our best fit plane describing the relation between gas fraction, stellar mass surface density and NUV-r colour. Interesting outliers from this plane include gas-rich red sequence galaxies that may be in the process of regrowing their disks, as well as blue, but gas-poor spirals.

description: This study is a first synthesis focused on incised-valleys located within the inner shelf of the Bay of Biscay. It is based on previously published results obtained during recent seismic surveys and coring campaigns. The morphology of the valleys appears to be strongly controlled by tectonics and lithology. The Pleistocene sedimentary cover of the shelf is very thin and discontinuous with a maximum thickness ranging between 30 and 40 m in incised-valley fills. Thus the incised bedrock morphology plays a key-role by controlling hydrodynamics and related sediment transport and deposition that explains some variations of those incised-valley fills with respect to the previously published general models.

description: The new contribution to the non-diagonal matrix element M_12 of the neutral B_s meson system is investigated in a supersymmetric extension of the standard model based on the discrete Q6 family symmetry. We assume that CP is explicitly, but softly broken only by the b terms in the soft supersymmetry breaking sector. We find that the new contributions to M_12 are real, and that nevertheless there exists an observable difference in the CP phase compared with the standard model. We focus our attention on the flavor-specific CP asymmetry a_fs^s, and find that a_fs^s of the model is mostly negative and its size can be one order of magnitude larger the standard model value. This prediction is consistent with the current experimental value, and can be experimentally tested in the near future.

description: We report that the major features in the temperature dependence of dc and ac magnetization of a well-known spin-chain compound, Ca3Co2O6, which has been known to exhibit two complex magnetic transitions due to geometrical frustration (one near 24 K and the other near 10 K), are found to be qualitatively unaffected in its nano form synthesized by high-energy ball-milling. However, the multiple steps in isothermal magnetization - a topic of current interest in low-dimensional systems - known for the bulk form well below 10 K is absent in the nano particles. We believe that this finding will be useful to the understanding of the 'step' magnetization behavior of such spin-chain systems.

description: SMM J04542-0301 is an extended (~1 arcmin) sub-mm source located near the core of the cluster MS0451.6-0305. It has been suggested that part of its emission arises from the interaction between a LBG and two EROs at z~2.9 that are multiply-imaged. However, the dramatic resolution difference between the sub-mm map and the optical/NIR images make it difficult to confirm this hypothesis. In this paper, we present a deep (~ 10 microJy/beam), high resolution (~2 arcsec) 1.4 GHz radio map of the cluster core, in which we have identified 6 sources located within SMM J04542-0301. The strong lensing effect in the radio data has been quantified by constructing a new lens model of the cluster. The brightest and most extended of these sources (RJ) is located in the middle of the sub-mm emission, and has no obvious counterpart in the optical/NIR. Three other detections (E1, E2 and E3) seem to be associated with the images of one of the EROs. The last two detections (CR1 and CR2), for which no optical/NIR counterpart have been found, seem to constitute two relatively compact emitting regions embedded in a ~5 arcsec extended radio source located at the position of the sub-mm peak. The presence of this extended component can only be explained if it is being produced by a lensed region of dust obscured star formation in the center of the merger. A comparison between the radio and sub-mm data at the same resolution suggests that E1, E2, E3, CR1 and CR2 are associated with the sub-mm emission. The radio observations provide strong observational evidence in favor of the merger hypothesis. However, the question if RJ is also contributing to the observed sub-mm emission remains open. These results illustrate the promising prospects for radio interferometry and strong gravitational lensing to study the internal structure of SMGs.

description: A novel heterogeneous catalytic nanomaterial based on a molybdenum cluster-based halide (MC) and a single-layered copper hydroxynitrate (CHN) was first prepared by colloidal processing under ambient conditions. The results of the elemental composition and crystalline pattern indicated that CHN was comprehensively synthesized with the support of the MC compound. The absorbing characteristic in the ultraviolet and near-infrared regions was promoted by both of the ingredients. The proper chemical interaction between the materials is a crucial reason to modify the structure of the MCs and only a small decrease in the magnetic susceptibility of CHN. The heterogeneous catalytic activity of the obtained MC@CHN material was found to have a high efficiency and excellent reuse when it is activated by hydrogen peroxide (H2O2) for the degrading reaction of the organic pollutant at room temperature. A reasonable catalytic mechanism was proposed to explain the distinct role of the copper compound, Mo6 compound, and H2O2 in the production of the radical hydroxyl ion. This novel nanomaterial will be an environmentally promising candidate for dye removal.
Aggregation of chemotactic organisms in a differential flow

description: We study the effect of advection on the aggregation and pattern formation in chemotactic systems described by Keller-Segel type models. The evolution of small perturbations is studied analytically in the linear regime complemented by numerical simulations. We show that a uniform differential flow can significantly alter the spatial structure and dynamics of the chemotactic system. The flow leads to the formation of anisotropic aggregates that move following the direction of the flow, even when the chemotactic organisms are not directly advected by the flow. Sufficiently strong advection can stop the aggregation and coarsening process that is then restricted to the direction perpendicular to the flow.
The Unfortunates': prostitutes transported to Van Diemen's Land 1822‚Äö-1843
Creators: name: Leppard-Quinn, CJ
Publisher: name: University Of Tasmania

description: Since historians first began to mine the records of the 160,000 men, women and children who were transported to the Australian colonies, the mention of prostitution has titillated researchers and the general public. The prostitute was a highly visible and public figure. Unlike the pickpocket, smuggler, extortionist or forger, each of whom strove to be invisible, the prostitute relied on her visibility to earn a living. However unlike her secretive companions the prostitute's activity was not illegal, yet her visibility made her a convenient scapegoat for many of the fears and failings of contemporary society. In Australia's convict history she is equally visible by virtue of a clear annotation on her convict record. During the nineteenth century it was commonplace to describe all female convicts as prostitutes, and this usage was adopted by some historians in the mid twentieth century. While the misconception was the legacy of nineteenth-century class, cultural and gendered misunderstandings, twentieth-century historians internalised those nineteenth-century stereotypes. In the 1970s the female convict was reinvented as a hardworking family maker and the label of 'prostitute' was reserved for a few marginalized, debauched incorrigibles. That attempt to exonerate the reputation of the majority, firmly positioned the prostitute as an outcast. The label of 'prostitute' on the convict records has been accepted as a sign of immorality or 'badness'. We accept that women were questioned about prostitution, as their replies were recorded by the thousands. Yet prostitution was not a criminal offence and women were not transported for being prostitutes. Indeed to be a prostitute was no more indictable than being a laundress or a housemaid. It was the criminal acts which were performed by the prostitute, laundress or housemaid which brought them to Van Diemen's Land. The glaring question which historians have failed to ask is, 'Why was the question posed, and why was their affirmation recorded?' From their arrest in Britain until their freedom in Van Diemen's Land the label remained fixed on some women's records. To what use was that information put, and how significant was it in determining outcomes for the women? How differently were they treated? The annotation is present on a sufficient number of records to provide answers to some of the questions which have hitherto been overlooked.
Steady-state analysis of nonlinear networks.
Creators: name: Agnew, David George
Publisher: name: University of British Columbia
Year: 2011

description: In this thesis the use of the digital computer in determining the steady-state response of nonlinear networks is investigated. Two classes of such networks, forced oscillating networks and self-oscillating networks, are considered. For the first class, a method of obtaining the network equations is developed, and an algorithm for calculating the numerical solution is obtained. For the second class, the development is restricted to those networks which can be described by [ Formula omitted ] and the previous algorithm is extended to solve this problem. For both classes, a substitution is developed which can expedite the analysis when the nonlinearities are exponential in character. The effectiveness of the methods is demonstrated by examples.

description: Printed electronics implies the use of low-cost, scalable, printing technologies to fabricate electronic devices and circuits on flexible substrates, such as paper or plastics. The development of this new electronic is currently expanding because of the emergence of the internet-of-everything. Although lot of attention has been paid to functional inks based on organic semiconductors, another class of inks is based on nanoparticles obtained from exfoliated 2D materials, such as graphene and metal sulfides. The ultimate scientific and technological challenge is to find a strategy where the exfoliated nanoparticle flakes in the inks can, after solvent evaporation, form a solid which displays performances equal to the single crystal of the 2D material. In this context, a printed layer, formed from an ink composed of nano-flakes of TiS2 intercalated with hexylamine, which displays thermoelectric properties superior to organic intercalated TiS2 single crystals, is demonstrated for the first time. The choice of the fraction of exfoliated nano-flakes appears to be a key to the forming of a new self-organized layered material by solvent evaporation. The printed layer is an efficient n-type thermoelectric material which complements the p-type printable organic semiconductors The thermoelectric power factor of the printed TiS2/hexylamine thin films reach record values of 1460 µW m−1 K−2 at 430 K, this is considerably higher than the high value of 900 µW m−1 K−2 at 300 K reported for a single crystal. A printed thermoelectric generator based on eight legs of TiS2 confirms the high-power factor values by generating a power density of 16.0 W m−2 at ΔT = 40 K.

description: We propose a novel approach for efficient tuning of the transmission characteristics of metamaterials through a continuous adjustment of the lattice structure, and confirm it experimentally in the microwave range. The concept is rather general and applicable to various metamaterials as long as the effective medium description is valid. The demonstrated continuous tuning of metamaterial response is highly desirable for a number of emerging applications of metamaterials including sensors, filters, switches, realizable in a wide frequency range.

description: A variety of poly(N-isopropylacrylamide) (PIPAAm)-grafted surfaces have been reported for temperature-controlled cell adhesion/detachment. However, the surfaces reported to date need further improvement to achieve good outcomes for both cell adhesion and detachment, which are inherently contradictory behaviors. This study investigated the effects of terminal cationization and length of grafted PIPAAm chains on temperature-dependent cell behavior. PIPAAm brushes with three chain lengths were constructed on glass coverslips via surface-initiated reversible addition-fragmentation chain transfer (RAFT) polymerization. Terminal substitution of the grafted PIPAAm chains with either monocationic trimethylammonium or nonionic isopropyl moieties was performed through the reduction of terminal RAFT-related groups and subsequent thiol-ene reaction with the corresponding acrylamide derivatives. Although the thermoresponsive properties of the PIPAAm brush surfaces were scarcely affected by the terminal functional moiety, the zeta potentials of the cationized PIPAAm surfaces were higher than those of the nonionized ones, both below and above the phase transition temperature of PIPAAm (30°C). When bovine endothelial cells were cultured on each surface at 37°C, the number of adherent cells decreased with longer PIPAAm. Notably, cell adhesion on the cationized PIPAAm surfaces was higher than that on the nonionized surfaces. This terminal effect on cell adhesion gradually weakened with increasing PIPAAm length. In particular, long-chain PIPAAm brushes virtually showed cell repellency even at 37°C, regardless of the termini. Interestingly, moderately long-chain PIPAAm brushes promoted cell detachment at 20°C, with negligible terminal electrostatic interruption. Consequently, both cell adhesion and detachment were successfully improved by choosing an appropriate PIPAAm length with terminal cationization.

description: We compute the properties of singlet and triplet bipolarons on two-dimensional lattices using the continuous time quantum Monte Carlo algorithm. Properties of the bipolaron including the total energy, inverse mass, bipolaron radius and number of phonons associated with the bipolaron demonstrate the qualitative difference between models of electron phonon interaction with long-range interaction (screened Fröhlich) and those with purely local (Holstein) interaction. A major result of our survey of the parameter space is the existence of extra-light hybrid singlet bipolarons consisting of an on-site and an off-site component on both square and triangular lattices. We also compute triplet properties of the bipolarons and the pair dispersion. For pair momenta on the edge of the Brillouin zone of the triangular lattice, we find that triplet states are more stable than singlets.
Dwelling adaptation for sustainability:Improving interventions for energy efficiency, comfort and equity in Tasmania
Creators: name: Watson, PL
Publisher: name: University Of Tasmania
Year: 2023

description: In Tasmania it is common for householders in disadvantaged circumstances to live in uncomfortable and energy inefficient housing, which creates sustainability and affordability challenges. Adapting dwellings and dwelling practices to improve comfort and energy efficiency can help to create healthier, more affordable and more equitable living conditions. Yet, householders dwelling in disadvantaged circumstances who would benefit most from adaptations tend to be the people with the least adaptive capacity. Interventions encouraging dwelling adaptation for energy efficiency and comfort have had limited impact in Tasmania. I argue that limited effectiveness of interventions is in part due to their generalised designs. This investigation seeks to contribute to the creation of more effective interventions to support households with low adaptive capacity in Tasmania. To this end the study asks in Tasmania, what measures could be taken by housing stakeholders to improve the design of interventions that encourage dwelling adaptation for improved comfort and energy efficiency in households with low adaptive capacity?

description: We investigate the quantum dynamics of a quadratic-quartic anharmonic oscillator formed by a potential well between two potential barriers. We realize this novel potential shape with a superconducting circuit comprised of a loop interrupted by two Josephson junctions, with near-zero current bias and flux bias near half a flux quantum. We investigate escape out of the central well, which can occur via tunneling through either of the two barriers, and find good agreement with a generalized double-path macroscopic quantum tunneling theory. We also demonstrate that this system exhibits an "optimal line" in current and flux bias space along which the oscillator, which can be operated as a phase qubit, is insensitive to decoherence due to low-frequency current fluctuations.

Universal decay rule for reduced widths

Year: 2009
Subjects: subject: Nuclear Theory (nucl-th)
subject: FOS: Physical sciences

description: Emission processes including $α$-decay, heavy cluster decays, proton and di-proton emission are analyzed in terms of the well known factorisation between the penetrability and reduced width. By using a shifted harmonic oscilator plus Coulomb cluster-daughter interaction it is possible to derive a linear relation between the logarithm of the reduced width squared and the fragmentation potential, defined as the difference between the Coulomb barrier and Q-value. This relation is fulfilled with a good accuracy for transitions between ground states, as well as for most $α$-decays to low lying $2^+$ excited states. The well known Viola-Seaborg rule, connecting half lives with the Coulomb parameter and the product between fragment charge numbers, as well as the Blendowke scalling rule connecting the spectroscopic factor with the mass number of the emitted cluster, can be easily understood in terms of the fragmentation potential. It is shown that the recently evidenced two regions in the dependence of reduced proton half-lives versus the Coulomb parameter are directly connected with the corresponding regions of the fragmentation potential.

description: To improve the therapeutic potential of β-cyclodextrin (β-CD)-threaded acid-degradable polyrotaxanes (β-CD PRXs) in cholesterol-related metabolic disorders, we investigated the effect of carboxylation of β-CD PRXs on intracellular uptake. In this study, we established a synthetic method for the modification of carboxylalkyl carbamates on β-CD PRXs without degradation and synthesized three series of carboxyalkyl carbamate group-modified β-CD PRXs with different alkyl spacer lengths. The modification of carboxymethyl carbamate (CMC), carboxyethyl carbamate (CEC), and carboxypropyl carbamate (CPC) on the β-CD PRXs slightly reduced the interaction of the PRXs with the lipid layer model compared with the modification of 2-(2-hydroxyethoxy)ethyl carbamate (HEE-PRX), which was used in our previous studies. However, all the carboxylated β-CD PRXs showed a significantly stronger interaction with a protein model compared with HEE-PRX. The carboxylated β-CD PRXs showed significantly high intracellular uptake, through macrophage scavenger receptor A (MSR-A)-mediated endocytosis, in MSR-A-positive RAW 264.7 cells compared with HEE-PRX. Interestingly, the carboxylated β-CD PRXs also showed significantly higher intracellular uptake even in MSR-A-negative cells compared with HEE-PRX. Carboxylated β-CD PRXs are considered to strongly interact with other membrane proteins, resulting in high intracellular uptake. The length of the alkyl spacer affected the intracellular uptake levels of carboxylated PRXs, however, this relationship was varied for different cell types. Furthermore, none of the carboxylated β-CD PRXs exhibited cytotoxicity in the RAW 264.7 and NIH/3T3 cells. Altogether, carboxylation of β-CD PRXs is a promising chemical modification approach for their therapeutic application because carboxylated β-CD PRXs exhibit high cellular internalization efficiency in MSR-A-negative cells and negligible toxicity.

description: We combine new ASTE/AzTEC 1.1 mm maps of the galaxy pair NGC 1512/1510 with archival Spitzer IRAC and MIPS images covering the wavelength range 3.6--160 um from the SINGS project to derive accurate dust masses in each galaxy, and in sub--galactic regions in NGC 1512. The two galaxies form a pair consisting of a large, high--metallicity spiral (NGC 1512) and a low metallicity, blue compact dwarf (NGC 1510). The derived total dust masses are (2.4+/-0.6) 10^7 Msun and (1.7+/-3.6) 10^5 Msun for NGC 1512 and NGC 1510, respectively. The derived ratio of dust mass to H I gas mass for the galaxy pair (0.0034) is much lower than expected, while regions within NGC 1512, specifically the central region and the arms, do not show such unusually low ratios; furthermore, the dust--to--gas ratio is within expectations for NGC 1510. These results suggest that a fraction of the H I included in the determination of the M_d/M_HI ratio of the NGC 1512/1510 pair is not associated with the star forming disks/regions of either galaxy. We also perform simple two--temperature (warm + cold) modified--blackbody fits to the far--infrared/mm data. The warm dust temperature of the low--metallicity NGC 1510 (~36 K) is substantially higher than that of the high--metallicity NGC 1512 (~24 K). In both galaxies, a substantial fraction (>93%) of the total dust mass is in a cool dust component, with temperatures 14--16 K for NGC 1512 and 15--24 K for NGC 1510. In contrast, the warm dust in the arms and central regions of NGC 1512 represents a much larger fraction of the total dust content, in agreement with the fact that all three regions have higher specific star formation rates than the average in the galaxy.

description: We use a simple tight-binding (TB) model to study electronic properties of free graphene flakes. Valence electrons of triangular graphene flakes show a shell and supershell structure which follows an analytical expression derived from the solution of the wave equation for triangular cavity. However, the solution has different selection rules for triangles with armchair and zigzag edges, and roughly 40000 atoms are needed to see clearly the first supershell oscillation. In the case of spherical flakes, the edge states of the zigzag regions dominate the shell structure which is thus sensitive to the flake diameter and center. A potential well that is made with external gates cannot have true bound states in graphene due to the zero energy band gap. However, it can cause strong resonances in the conduction band.

description: Many researchers working on the development of dye-sensitized solar cells (DSCs) continue to focus on the synthesis of photoanode materials with high surface area, along with high light scattering ability to enhance light harvesting efficiency (LHE). Meanwhile, dye packing density, which also impacts the LHE significantly, is often overlooked. Solvothermally synthesized anatase TiO2 nanoparticles (SANP) were obtained by a new and simple approach using a mixed solvent, ethanol and acetic acid. SANP were applied in photoanodes of DSCs using either metal-free organic dye (D149) or organometallic (N719) dyes. Dye loading (packing density) was correlated with the isoelectric point (IEP) in addition to light scattering effects were shown to determine the devices photovoltaic efficiency (PCE); specifically when compared with ones employing commercially available TiO2 nanoparticles. SANP photoanodes sensitized with D149 dye were found to be optimised at 10 µm, yielding a PCE of 6.9%, superior to for transparent or transparent + scattering films from the commercial source (5.6% and 5.9%, respectively). Furthermore, a 7.7% PCE was achieved using a SANP photoanode sensitized with N719 dye, with 7.2% seen for the transparent photoanode and 7.9% with a scattering layer. The high PCEs of of SANP devices are attributed to the high dye loading capability in addition to light scattering. A further point of interest is that even with the increased reactivity of the surface towards dye adsorption, we did not observe any significant increase in recombination with the redox mediator, presumably due to the increased dye loading providing better shielding.

description: We study surface operators in the N=4 supersymmetric Yang-Mills theories with gauge groups SO(n) and Sp(2n). As recently shown by Gukov and Witten these theories have a class of rigid surface operators which are expected to be related by S-duality. The rigid surface operators are of two types, unipotent and semisimple. We make explicit proposals for how the S-duality map should act on unipotent surface operators. We also discuss semisimple surface operators and make some proposals for certain subclasses of such operators.

Governmental policies concerning residential condominium development in British Columbia
Creators: name: Conradi, Andrew Paul
Publisher: name: University of British Columbia
Year: 2011

description: The provision of adequate housing for all its people remains a problematical objective for Canada. A new type of cooperative housing—condominium--has recently received specific legal sanction in most provinces and territories in Canada with the exception of Newfoundland, Prince Edward Island and the North-West Territories. This thesis considers this innovative housing concept in light of the population trends and housing needs of British Columbia and shows that condominium is merely one of a variety of alternative housing types but one that may prove increasingly effective in helping meet future housing demand. The historical evolution of the condominium concept is outlined after which the author carefully distinguishes between condominiums and other similar forms of housing. The author affirms that Federal and Provincial housing policies do not discriminate against residential condominiums and further hypothesizes that Municipal housing policies and bureaucratic procedures do not frustrate their development, in contrast with the findings of a similar study concerning a similar form of housing—continuing cooperatives, which found that a lack of specific Provincial and Municipal policy had retarded their formation. Governmental policy is reviewed in general and its specific application to residential condominium development is assessed with the conclusion generally confirming the author's original affirmation and hypothesis.
Different white people: communists, unionists and Aboriginal Rights 1946-1972
Creators: name: Wilson, DM
Publisher: name: University Of Tasmania
Year: 2023

description: This thesis is an examination of left-wing activist contributions to the Aboriginal rights movement in Australia, with focus upon three important campaigns: > Pilbara pastoral walk-offs in Western Australia 1946 ‚Äö- 1949 > Protests about weapons testing programs in Central Australia 1946 ‚Äö- late 1950s > Aboriginal walk-offs in the Northern Territory 1966 ‚Äö- early 1970s Information gathered from a broad range of sources (including archival materials, government records, newspapers and participants in this activism) is presented in three mini-narratives. An eclectic assortment of characters features as campaigns progress from sheep stations, through deserts, to cattle stations. The issues in focus also shift, as conflicts over worker and human rights are overwhelmed by modern battleground disputes about lands and compensation. The study highlights left-wing collaboration, within a much broader pressure group of activists and organisations throughout Australia, working to advance the rights of Aboriginal people. Union support for Aboriginal rights variously ebbed and flowed during the period under investigation, but communists maintained vigorous solidarity throughout. Left-wing activism during the campaigns manifested in many forms, including provision of industrial advocacy and financial support, coordination of protest meetings and marches, hands-on assistance for Aboriginal activist communities, and comprehensive publicity of the stories in left-wing newspapers and journals. Artistic representation of disputes also featured in left-wing poetry, drama, film, music, caricature and literature. Inclusion of this activism in art adds colour to a narrative based so centrally around the dark subject at the heart of the investigation: the intolerable treatment of Aboriginal peoples that these activists were determined to change. The activism occurred during an exceptional period of Australian political history, when union power was at its height, and passionate communist endeavours endured amidst relentless pressures of the Cold War. The Aboriginal rights movement, buoyed by white activist support, grew steadily until the late 1960s when the Black Power model of Aboriginal-driven rights activism evolved, then prevailed. This study about three campaigns, in different regions of Australia across a time-span of nearly forty years, presents a compelling longitudinal examination of left-wing activism for Aboriginal rights. Activists established vital networks and mechanisms of support and exposure for Aboriginal people so adversely affected by the actions of pastoralists, governments and officials. Evidence presented in the thesis indicates that motivation for such ardent support emanated, in large part, from basic humanitarian desire to better others' lives.

description: The rock shelter site Klipfonteinrand 1 (KFR1), located on the edge of southern Africa’s Fynbos biome, was initially excavated by John Parkington in 1969. Due to difficulties resolving the stratigraphic sequence, the lack of age estimates, and generally poor organic preservation, the Middle Stone Age (MSA) components of the site have received limited attention. In this paper we report on the re-excavation, dating, palaeoecology, and cultural sequence recovered from a trench placed adjacent to Parkington’s original excavation. The refined sequence includes three stratigraphically distinct MSA components: a Howiesons Poort component dating to ~69 ka, and two earlier MSA components dating to ~85 ka and ~156 ka. These are overlain by two younger components dated to the late Pleistocene and early Holocene. Bedrock morphology at the site is complex, and the oldest component appears to be restricted to a small area of relatively deep (1.9 m) sediment accumulation towards the centre of the sheltered area. Phytoliths suggest limited change in floral communities near the site across the lowest three units—which include parts of marine isotope stages (MIS) 6, 5, and 4—reflecting the characteristic stability of the Fynbos biome. The stone artefacts in the oldest MSA component include large blades that are absent from the overlying strata, and that may be a distinct element of late MIS 6 technology in the area. Interestingly, neither the early MSA nor early Holocene components we describe here were encountered in the rear trench at the site, 3 m away, which instead produced a sequence dominated by marine isotope stage 2 occupation. KFR1 presents new insights into the archaeology of the earlier MSA in southern Africa, while also providing a cautionary note on the discontinuous and spatially variable nature of rock shelter occupation in the region.

description: We report on the synthesis of superconducting single crystals of FeSe, and their characterization by X-ray diffraction, magnetization and resistivity. We have performed ac susceptibility measurements under high pressure in a hydrostatic liquid argon medium up to 14 GPa and we find that TC increases up to 33-36 K in all samples, but with slightly different pressure dependences on different samples. Above 12 GPa no traces of superconductivity are found in any sample. We have also performed a room temperature high pressure X-ray diffraction study up to 12 GPa on a powder sample, and we find that between 8.5 GPa and 12 GPa, the tetragonal PbO structure undergoes a structural transition to a hexagonal structure. This transition results in a volume decrease of about 16%, and is accompanied by the appearance of an intermediate, probably orthorhombic phase.

description: RNA interference (RNAi) by small interfering RNAs (siRNAs) is a promising therapeutic approach. Because siRNA has limited intracellular access and is rapidly cleared in vivo, the success of RNAi depends on efficient delivery technologies. Particularly, polyion complexation between block catiomers and siRNA is a versatile approach for constructing effective carriers, such as unit polyion complexes (uPIC), core-shell polyion complex (PIC) micelles and vesicular siRNAsomes, by engineering the structure of block catiomers. In this regard, the flexibility of block catiomers could be an important parameter in the formation of PIC nanostructures with siRNA, though its effect remains unknown. Here, we studied the influence of block catiomer flexibility on the assembly of PIC structures with siRNA using a complementary polymeric system, i.e. poly(ethylene glycol)-poly(L-lysine) (PEG-PLL) and PEG-poly(glycidylbutylamine) (PEG-PGBA), which has a relatively more flexible polycation segment than PEG-PLL. Mixing PEG-PGBA with siRNA at molar ratios of primary amines in polymer to phosphates in the siRNA (N/P ratios) higher than 1.5 promoted the multimolecular association of uPICs, whereas PEG-PLL formed uPIC at all N/P ratios higher than 1. Moreover, uPICs from PEG-PGBA were more stable against counter polyanion exchange than uPICs from PEG-PLL, probably due to a favorable complexation process, as suggested by computational studies of siRNA/block catiomer binding. In in vitro experiments, PEG-PGBA uPICs promoted effective intracellular delivery of siRNA and efficient gene knockdown. Our results indicate the significance of polycation flexibility on assembling PIC structures with siRNA, and its potential for developing innovative delivery systems.
