description: We study the regularity of the extremal solution of the semilinear biharmonic equation $\bi u=\fλ{(1-u)^2}$, which models a simple Micro-Electromechanical System (MEMS) device on a ball $B\subset\IR^N$, under Dirichlet boundary conditions $u=\partial_νu=0$ on $\partial B$. We complete here the results of F.H. Lin and Y.S. Yang \cite{LY} regarding the identification of a "pull-in voltage" $\la^*>0$ such that a stable classical solution $u_\la$ with $0\la^*$. Our main result asserts that the extremal solution $u_{λ^*}$ is regular $(\sup_B u_{λ^*} <1)$ provided $ N \le 8$ while $u_{λ^*} $ is singular ($\sup_B u_{λ^*} =1$) for $N \ge 9$, in which case $1-C_0|x|^{4/3}\leq u_{λ^*} (x) \leq 1-|x|^{4/3}$ on the unit ball, where $ C_0:= (\frac{λ^*}{\overlineλ})^{1/3}$ and $ \barλ:= {8/9} (N-{2/3}) (N- {8/3})$.

description: We report on systematic ab-initio investigations of Co and Cr interlayers embedded in Fe(001)/MgO/Fe(001) magnetic tunnel junctions, focusing on the changes of the electronic structure and the transport properties with interlayer thickness. The results of spin-dependent ballistic transport calculations reveal options to specifically manipulate the tunnel magnetoresistance ratio. The resistance area products and the tunnel magnetoresistance ratios show a monotonous trend with distinct oscillations as a function of the Cr thickness. These modulations are directly addressed and interpreted by means of magnetic structures in the Cr films and by complex band structure effects. The characteristics for embedded Co interlayers are considerably influenced by interface resonances which are analyzed by the local electronic structure.

The results suggest that a configuration matching that at the previous minimum was reached during 2008, but that the flow band corresponding to the new cycle has been moving more slowly towards the equator than was observed in the previous cycle, resulting in a gradual increase in the apparent length of the cycle during the 2007 -- 2008 period. The current position of the lower-latitude fast-rotating belt corresponds to that seen around the onset of activity in the previous cycle.

description: The presence of first sharp diffraction peaks in the partial structure factors is investigated in computer simulations of molten mixtures of alkali halides. An intermediate range ordering appears for the Li+ ions only, which is associated with clustering of this species and is not reflected in the arrangement of other ions. This ordering is surprising in view of the simplicity of the interionic interactions in alkali halides. The clustering reflects an incomplete mixing of the various species on a local length scale, which can be demonstrated by studying the complementary sub-space of cations in the corresponding pure alkali halides by means of a void analysis.

The problem is considered in two-dimensional formulation and solved numerically using in-house software based on the Muller boundary integral equations. Our results highlight the key role of the edge taper which can be defined for DLAs similarly to the theory of reflector antennas. A new feature revealed is the relation between the optimal edge taper needed to achieve the highest possible directivity and the permittivity of the lens material.

We find that the effect of eccentricity fluctuation is modest in semicentral Au+Au collisions but significantly enhances v_2 in Cu+Cu collisions.

Multi-channel Opportunistic Access: A Case of Restless Bandits with Multiple Plays

description: This paper considers the following stochastic control problem that arises in opportunistic spectrum access: a system consists of n channels (Gilbert-Elliot channels)where the state (good or bad) of each channel evolves as independent and identically distributed Markov processes. A user can select exactly k channels to sense and access (based on the sensing result) in each time slot. A reward is obtained whenever the user senses and accesses a good channel. The objective is to design a channel selection policy that maximizes the expected discounted total reward accrued over a finite or infinite horizon. In our previous work we established the optimality of a greedy policy for the special case of k = 1 (i.e., single channel access) under the condition that the channel state transitions are positively correlated over time. In this paper we show under the same condition the greedy policy is optimal for the general case of k >= 1; the methodology introduced here is thus more general. This problem may be viewed as a special case of the restless bandit problem, with multiple plays. We discuss connections between the current problem and existing literature on this class of problems.

The optical problems of the Ritchey-Chretien astronomical telescope
Creators: name: Vyakaranam, MLN
Publisher: name: University Of Tasmania
Year: 2023

description: The optical design principles of the two-mirror Ritchey-Chretien telescope objective system are developed systematically, starting from fundamentals. The third-order aberration coefficients of Buchdahl are derived for such a system and based on these coefficients, expressions for the first of the extra-axial curvature coefficients of the mirrors which provide aplanatic condition at the Cassegran focus are derived. numerical example (proposed Anglo-Australian 150-inch telescope) is considered to illustrate the principles. Third-order correction to achieve aplanatism is found to be inadequate when spot diagram analysis is made. The expressions for the fifth-order spherical aberration coefficient, `˜í¬¿_1`, and linear coma coefficients, `˜í¬¿_2`, `˜í¬¿_3`, for the two-mirror system are then derived and are used to achieve aplanatic condition to fifth-order. When this is applied to the numerical example, the performance of the system is found to be extremely good. The profiles of the mirrors of the seventh-order aplanatic system are found to be scarcely distinguishable from those of the fifth-order aplanatic system. The mirrors are then considered as two hyperboloids, based on third-order aberrations, and it is noticed that the curvature coefficients of these mirrors and the performance of such a system is not far removed from that of the fifth-order aplanatic system, justifying the popular view. A consideration of the aberration balance technique has brought the hyperboloid system still closer to the fifth-order system. The design principles of two types of secondary focus correctors to eliminate the residual astigmatism and field curvature of the aplanatic system are outlined. These are an aspheric plate with field flattener and a Rosin type doublet. The principles are successfully adopted to develop these correctors for the numerical example. With the farmer type of corrector, it is noticed that best correction canbe achieved if the Ritchey-Chretien mirror constants are slightly changed Rosin type corrector is associated with colour problems: Expressions for the prime focus aberrations are derived and the design principles of single plate and three-plate correctors to correct these aberrations are discussed: Two-plate correctors provide no practicable arrangement: The single plate corrector provides a small useful field, whereas the three-plate corrector offers more useful field. With these correctors in place, the prime focus largely suffers from higher order aberrations. The conclusions are mostly derived from the numerical example. However, they are valid for a wide range of parameters.
Evolution of very low mass pre-main sequence stars and young brown dwarfs under accretion: A phenomenological approach

description: In the poster presented in Cool Star 15, we analyzed the effect of disk accretion on the evolution of very low mass pre-main sequence stars and young brown dwarfs and the resulting uncertainties on the determination of masses and ages. We use the Lyon evolutionary 1-D code assuming a magnetospheric accretion process, i.e., the material falls covering a small area of the radiative surface, and we take into account the internal energy added from the accreted material as a free parameter $ε$. Even if the approach to this problem is phenomenological, our formalism provides important hints about characteristics of disk accretion, which are useful for improved stellar interior calculations. Using the accretion rates derived from observations our results show that accretion does not affect considerably the position of theoretical isochrones as well as the luminosity compared with standard non-accreting models. See more discussions in a forthcoming paper by Gallardo, Baraffe and Chabrier (2008).

description: Isoperla miwok Bottorff & Szczytko (Figs. 9 a-d, 20 d) Isoperla miwok Bottorff & Szczytko 1990. Holotype ♂, California, El Dorado County, Indian Creek, 3.3 km NE Michigan Bar Bridge. Male. Aedeagus: sclerotized posterior process absent; body with one small posterior lobe, one large dorsal lobe and a pair of small pointed lobes on apicolateral margins (Fig. 9 a-b); a pair of long curved patches of spinulae on posteroventral surface (Fig. 9b), and a broad patch of spinules on the posteroapical surface (Figs. 9 a-c). Abdominal terga 8- 9, 9, 9-10: without stout spinulae or long stout setae. Posterolateral margins of at least abdominal segment 8 with scale-like setae clustered in brushes of several setae. Paraprocts: curved dorsally, length if straightened subequal to combined first and second cercal segments, tapering abruptly to blunt apices (Fig. 9c). Vesicle: lobe barely perceptible, vestigial when present, widest at base with broadly rounded apex (Fig. 9d). Isoperla miwok is most similar to the other species included in the I. sobria complex based on the absence of an aedeagal posterior sclerotized process, and presence of stout spinules arranged in variable patches (Table 1). It is distinctive among the western Nearctic species in possessing a double band of stout spinulae on the aedeagal posterobasal margin. The current study aedeagal description conforms to the previous description. However, the live everted and fixed aedeagus lacks the single extended tube-like lobe on the anteroapical margin (Bottorff et al. 1990, fig. 4). The anterior margin in this study possesses at least one anteromedian pair of inverted membrane areas (openings) which differs from the original description. A second smaller and more apical pair is also present. Clearing the everted and fixed aedeagus in KOH allowed observation of the anteroapical and anteromedian inverted processes inside the aedeagal body (Fig. 20d, dorsal aspect providing the best view).

Studies on human T lymphocyte colonies
Creators: name: Woods, Gregory Mark
Publisher: name: University Of Tasmania
Year: 2023

description: This thesis examined the ability of human T lymphocytes to form colonies in semisolid agar. A two step procedure requiring a continued supply of PHA, a source of SRBC during the agar culture and a high agar concentration to restrict the freely mobile proliferating cells was developed for the culturing of human lymphocytes in semisolid agar. The technique was later modified by replacing PHA with an IL2-containing lymphokine during the agar phase. The T cell nature of the colonies was confirmed by their ability to form E-rosettes. An absence of colonies from E-rosette depleted cells compared to E-rosette enriched cells strengthened this finding and indicated that the colony forming cells were T cells. The requirement for SRBC was investigated and it was found that red cells from a variety of mammalian sources supported colony formation through the elaboration of soluble factors which diffused through the agar and did not require cell-cell contact for their expression. Experiments relating to the cellular interactions involved in colony formation emphasised that cooperation between at least three cell populations was essential. The interaction of these cells could be described by two reactions. The first reaction required an adherent cell (probably monocyte) population which, together with PHA, provided the necessary signals for T cell activation. The activated T cells interacted during the second or proliferative reaction. In response to PHA, accessory T cells released IL2 which permitted colony forming cells to proliferate. Thus PHA-induced T colony formation required the cooperation of adherent cells for the activation reaction (T ->T') and IL2-producing T cells for the proliferative reaction (T' -> nT'). The microfilament/Microtubule network and the redistribution of receptor :membrane complexes appeared to be an important feature of T cell function with regard to both mitogen and IL2 binding. Utilising the colony forming ability of T lymphocytes studies on radiation induced mitotic death were carried out. Colony formation was sensitive to low doses of irradiation although PHA offered a limited degree of protection when cells were irradiated prior to, or in the early stages of activation. This protection could be explained by activities of repair enzymes which coincided with early cellular activation events. The human T lymphocyte colony assay was found to be a valuable in vitro model for studying the steps involved in T lymphocyte activation and proliferation.

description: Based on the theory of mutual coherence of light from an extended incoherent quasi-monochromatic source (providing a basis of stellar interferometry) we estimate the degree of light incoherence due to quantum-gravitational fluctuations of the background metric. It is shown that the stellar interferometry observational data considered in the literature for a last few years as a manifestation against the Planck scale quantum-gravitational fluctuations of the background metric have no chance for detecting such an effect.

Large $N_c$ Expansion and the Parity Violating $π, N, Δ$ Couplings

description: In the limit of large $N_c$ we first consider the $N_c$ ordering of the various parity violating $π, N, Δ$ couplings. Then we derive the relations among these couplings and consistency relations from the stability of these couplings under the chiral loop corrections with and without the mass splitting between $N$ and $Δ$. Especially we find that $h_Δ=-{3\over \sqrt{5}}h_π$ in the large $N_c$ limit, which correctly reproduces the relative sign and magnitude of the "DDH" values for these PV couplings.
Dust coagulation in star formation with different metallicities

description: Dust grains coagulate into larger aggregates in dense gas. This changes their size distribution and possibly affects the thermal evolution of star-forming clouds. We here investigate dust coagulation in collapsing pre-stellar cores with different metallicities by considering the thermal motions of grains. We show that coagulation does occur even at low metallicity $\sim 10^{-6} \Zsun$. However, we also find (i) that the H$_2$ formation rate on dust grains is reduced only after the majority of H$_2$ is formed; and (ii) that the dust opacity is modified only after the core becomes optically thick. Therefore, we conclude that the effects of dust coagulation can safely be neglected in discussing the temperature evolution of the pre-stellar cores for any metallicity as long as the grain motions are thermal.

We explain in depth how our analysis differs from the work of other groups, what advance this implies in terms of our understanding, and what new physics about the deconfined particle source this allows us to recognize. We answer several frequently asked questions, presenting a transcript of a discussion regarding our data analysis. We show that the final NA49 data at 40, 80, 158 AGeV lead to a remarkably constant extensive thermal chemical-freeze-out properties of the fireball. We discuss briefly the importance of thermal hadronization pressure.

description: We present a data storage scheme for sensor networks that achieves the targets of encryption and distributed storage simultaneously. We partition the data to be stored into numerous pieces such that at least a specific number of them have to be brought together to recreate the data. The procedure for creation of partitions does not use any encryption key and the pieces are implicitly secure. These pieces are then distributed over random sensors for storage. Capture or malfunction of one or more (less than a threshold number of sensors) does not compromise the data. The scheme provides protection against compromise of data in specific sensors due to physical capture or malfunction.

description: We study gaugino mass generation in the context of semi-direct gauge mediation models, where the messengers are charged under both the hidden sector and the standard model gauge groups while they do not play important roles in dynamical supersymmetry breaking. We clarify the cancellation of the leading contributions of the supersymmetry breaking effects to the gaugino mass in this class of models in terms of the macroscopic effective theory of the hidden sector dynamics. We also consider how to retrofit the model so that we obtain the non-vanishing leading contribution to the gaugino mass.

In recent years, golf participation rates have increased rapidly across the globe. In the US, 18% more rounds of golf were reported in 2021 compared to 2019. To capitalize on this market, equipment manufacturers use computer models to optimize new equipment. Several researchers have developed models to predict the trajectory of a golf shot using the kinematics of the swing. However, the majority of published research is for modeling a driver. A previous study determined that amateur golfers hit the ground before the ball on nearly one-third of iron shots. Therefore, to predict these shots, a model needs to account for the clubhead striking the ground. To date, no published models have considered the ground reaction forces (GRFs) experienced by the clubhead during a swing.
role of perception in flood plain management

description: The flood plain of the Fraser River in the Lower Fraser Valley is rapidly becoming urbanized, this being most evident in the municipality of Richmond located on Lulu Island. A problem arises due to the fact that the Fraser River is subject to frequent floods of varying magnitudes. To prevent flood damages a system of dykes has been constructed around Lulu Island. Evidence indicates, however, that even with the dykes there still exists a substantial residual flood hazard. A major flood in Richmond would constitute a financial disaster. Consequently, if development is to occur on the flood plain, additional adjustments to the flood hazard are necessary. The planning process in Richmond has apparently failed to recognize this necessity. To understand the observed breakdown in the planning process the literature suggests that the problem may be fruitfully studied by examining the decision-making process with respect to perception of the flood hazard and alternative adjustments to the hazard. The hypothesis proposed is that the planning officials are aware of the alternate adjustments but policies to implement these measures are not undertaken because of lack of support from the general public who do not perceive the flood problem or ways to cope with it. The methodology used to study the problem involves three steps. The first is the definition and description of flood plain management policy at all government levels operating in British Columbia. The second step is to identify the public decision-making process with respect to flood plain management. Interviews with key officials in this process are reported upon according to their perceptions of the flood hazard and adjustments to the flood hazard. The third step is to sample perceptions of flood plain land-users by means of a questionnaire to determine their perceptions of the hazard and adjustments. The study shows that the officials are aware of the hazard but do not adequately perceive non-structural adjustments. The general public is poorly informed and thus shows little concern about the subject. The results indicate that perception of the hazard is a major factor in the adjustment adoption process. It appears that a change in decision-makers' perceptions will be necessary to bring about a change in the planning practise with respect to flood plain management.

description: Aberrantly up-regulated activity of the type II transmembrane protease Matriptase-1 has been associated with the development and progression of a range of epithelial-derived carcinomas, and a variety of signaling pathways can mediate Matriptase-dependent tumorigenic events. During mammalian carcinogenesis, gain of Matriptase activity often results from imbalanced ratios between Matriptase and its cognate transmembrane inhibitor Hai1. Similarly, in zebrafish, unrestrained Matriptase activity due to loss of hai1a results in epidermal pre-neoplasms already during embryogenesis. Here, based on our former findings of a similar tumor-suppressive role for the Na+/K+-pump beta subunit ATP1b1a, we identify epithelial polarity defects and systemic hypotonic stress as another mode of aberrant Matriptase activation in the embryonic zebrafish epidermis in vivo. In this case, however, a different oncogenic pathway is activated which contains PI3K, AKT and NFkB, rather than EGFR and PLD (as in hai1a mutants). Strikingly, epidermal pre-neoplasm is only induced when epithelial polarity defects in keratinocytes (leading to disturbed Matriptase subcellular localization) occur in combination with systemic hypotonic stress (leading to increased proteolytic activity of Matriptase). A similar combinatorial effect of hypotonicity and loss of epithelial polarity was also obtained for the activity levels of Matriptase-1 in human MCF-10A epithelial breast cells. Together, this is in line with the multi-factor concept of carcinogenesis, with the notion that such factors can even branch off from one and the same initiator (here ATP1a1b) and can converge again at the level of one and the same mediator (here Matriptase). In sum, our data point to tonicity and epithelial cell polarity as evolutionarily conserved regulators of Matriptase activity that upon de-regulation can constitute an alternative mode of Matriptase-dependent carcinogenesis in vivo.

Golf balls are tested by the sport’s governing bodies to ensure that they conform to the Rules of Golf. The governing bodies don’t release the data from their conformance tests, however, so golfers have limited independent data on which to judge the marketing claims of the various manufacturers. The aim of this study was to compare the performance of a wide range of commercially available golf balls across multiple types of shot.

description: This publication covers experimental investigations made at the Division of Forest Products, Council for Scientific and Industrial Research, Melbourne, during the period December, 1940, to January, 1946, to determine the effect of temperature on the strength of wood, plywood and glued joints. The investigations deal with reversible changes in_ strength, elasticity, and the like which may accompany variations in the temperature of the material. Results show that all properties investigated are affected by temperature at some moisture content, in many instances to such an extent that serious error is introduced in mechanical testing and in design where this factor is not taken into account. Temperature coefficients may exceed one per cent of the value at 20¬¨‚àû C. per degree centigrade. Relations are given from which the effect of temperature on certain properties of a species can be estimated quantitatively with considerable confidence for a wide range of temperatures and moisture contents. PART I. deals with compression, bending, and toughness tests on Sitka spruce and five Australian species at nominal moisture contents of 8, 12, and 20 per cent. in the range - 20 to + 60¬¨‚àû C. Compression tests on these species were extended to zero moisture content and near saturation, in respective ranges of - 20 to + 90¬¨‚àû C. and - 20 to + 60¬¨‚àû C. In addition, two low density species were included in the compression tests. Two species were also examined in bending at zero moisture content from - 20 to + 80¬¨‚àû C. PART II. covers tests made at 15 per cent. nominal moisture content on standard size hoop pine specimens in compression and shear from zero to 40¬¨‚àû C. and in bending at 20 and 40¬¨‚àû C., also on 2 in. X 3/4 in. X 3/4 in. specimens of the same species in compression from - 20 to + 60¬¨‚àû C. PART III. describes tests on hoop pine plywood. At nominal moisture contents of 8, 12, and 20 per cent., tensile and crushing strengths were examined from - 20 to + 80¬¨‚àû C. Investigation of crushing strength was extended to include zero moisture content. Modulus of elasticity was examined at all the above moisture contents, but only from - 20 to + 60¬¨‚àû C. PART IV. discusses tests on casein, pheno-formaldehyde and urea-formaldehyde glued joints at temperatures from - 15 to + 60¬¨‚àû C. in the range 8 to 20 per cent moisture content. PART V. summarizes the more important features of the investigations in general terms and gives results of independent confirmatory tests.
