The ease by which yeast can be manipulated in conjunction with their similarities to cells of more complex metazoans makes many yeast species, particularly Saccharomyces cerevisae, very attractive models for the study of conserved evolutionary processes that occur in eukaryotes. The ability to functionally express heterologous genes in these cells has allowed the development of countless new and elegant approaches leading to detailed structure-function analysis of numerous mammalian genes. Of these, the most informative have been the studies involving the analysis of regulators that have no direct or obvious sequence orthologue in yeast, including members of the Bcl-2 family of proteins, caspases and tumour suppressors. Here we review the field and provide evidence that these studies have served to further understand mammalian apoptosis. © 2010 Macmillan Publishers Limited. All rights reserved.


Refugees walk along railway tracks from the United States to enter Canada at Emerson, Manitoba, Canada, February 26, 2017. REUTERS/Lyle Stafford EMERSON, Manitoba (Reuters) - Jaime French was jarred out of bed in Emerson, Manitoba early one morning this month by pounding at her front door, just yards from the U.S. border. A face peered in through the window, flanked in the darkness by others. Outside were 16 asylum seekers, arriving at one of the first houses they saw after crossing a lightly monitored border between Canada and the United States. "They banged pretty hard, then 'ring ring ring' the doorbell," said French, a mother of two young girls. "It was scary. That really woke me up." The town has become the front line of an emerging political crisis that is testing Canada's will to welcome asylum seekers. Hundreds of people, mainly from Africa but also the Middle East, are fleeing U.S. President Donald Trump's crackdown on illegal immigrants, migrants and refugee agencies say. Many asylum seekers say Trump's election and subsequent crackdown on illegal migrants spurred their plans to head north. Those arriving in Emerson come on foot in the dead of night, unnerving its 650 residents. Some fear the influx of unscreened migrants while others are frustrated by the cost and effort forced on the community. Prime Minister Justin Trudeau is under increased pressure from the left, which wants him to let more in, and from the right, which is fearful of an increased security risk. Trudeau must tread carefully to ensure the issue does not complicate relations with Trump. The cooling welcome in Emerson is a microcosm of growing discontent over Canada’s open door policy for refugees. Last week, an Angus Reid poll found that while 47 percent of respondents said Canada is taking in the right number of refugees, 41 percent said the number is already too high. (See the report) (http://angusreid.org/syrian-refugee-travel-ban/) "It could become a real political liability for the government," said Christian Leuprecht, a politics professor at the Royal Military College of Canada, noting that spring will lead to more crossings as travel gets easier. THAWING OUT IN THE KITCHEN After the 16 migrants left French's home, without being admitted, they found truck driver Brad Renout two doors down leaving for work. "I was going to leave them all outside," Renout said. "I figured, to hell with (them) for coming over the border in winter." When he saw children among the group, Renout allowed three women, three toddlers and two teenagers into his kitchen. Early Sunday, Reuters witnessed at least seven migrants bundled in new parkas and bulging backpacks walking into Canada from Minnesota, following railway tracks in the icy dark. Ismail, a 25-year-old Somali man, said they had walked for 22 hours without sleep across North Dakota. As police lights flashed distantly, Ismail said he was afraid to walk toward them. He thought the group was still on U.S. soil. Canadian police caught up with them shortly afterward and arrested them for illegally entering Canada. The group squeezed, uncuffed, into a police minivan and headed to a government office for questioning. "We feel sorry for the people," said retired grain farmer Ken Schwark. "I just wish they would come through the legal way." A 2004 agreement between Canada and the United States means asylum seekers must submit applications in the United States if they arrive there first. But if they find a way into Canada, they can apply for refugee status there. It's an avenue that has spurred north illegal migrants in the United States, especially Somalis settled in Minnesota, which shares a land border with Manitoba. After pricey taxi rides to North Dakota, many like Ismail walk for hours in darkness and -20 C (-4°F) temperatures to dimly lit Emerson, in the shadow of the bright glare of the international border crossing. The lucky migrants get rides dropping them off less than a mile from Noyes, Minnesota, within sight of Emerson's southern edge. From there they duck under a metal crossing-arm gate, walk across the border and often use their own cellphones to dial police. Others are dropped 30 or more kilometers (19 miles) from the border, and follow rail lines into Emerson, crossing a border marked in most areas only by scattered concrete boundary markers. Faye Suderman, a four-decade Emerson resident, said she is sympathetic but draws a line between those fleeing persecution and those who have simply run out of chances in the United States: "How difficult is it to get rid of those people and give help to those truly in need?" Emerson Cafe manager Jacquelyn Reimer, who has fed shivering asylum seekers for free, wondered why the Canadian government is helping refugees when the country has its own homeless problem. "We can't even take care of our own," she said. Due to its border-hugging location, Emerson's encounters with migrants are not new, but the scale of their arrivals is. In the first two months of 2017, 143 mainly Somali people walked illegally over the border into Emerson, representing 40 percent of Manitoba's full-year total in 2015/16. Quebec and British Columbia are the two other major illegal crossing points, but police there refused to provide data. Emerson residents don’t encounter the migrants for long before police arrive and whisk them to the local Canada Border Services Agency (CBSA) office for questioning. From there, they are ferried to Winnipeg, Manitoba's capital, to file asylum claims.     Despite some residents’ fears, asylum-seekers have not caused any trouble, said Bill Spanjer, Emerson's emergency coordinator. "They're going to be on their best behavior because otherwise their refugee claim is certainly going to be affected," he said. When police receive a call, they summon the town's volunteer firefighters to treat any health concerns, as the nearest ambulance is 25 minutes away. In December, two men from Ghana lost all of their fingers to frostbite. Firefighter callouts cost Emerson about C$500 each time. The costs may add up to C$30,000 since last spring, representing 10 percent of its firefighting budget, said Emerson-Franklin's elected leader Greg Janzen. The provincial government directed more resources to Emerson last week, including paramedics and paralegal and transportation services. Since the influx sped up in January, the strain on Emerson has grown. In early February, police intercepted 18 migrants from Somalia and Djibouti and CBSA asked Emerson to temporarily house them in the town's ice rink. Brenda Piett and other volunteers laid folding banquet tables on the concrete floor, and layered them with blankets for makeshift mattresses. At the migrants’ request, they served white bread sandwiches with Nutella hazelnut spread. "The groups are getting bigger, and the stories are scary, how far they’ve walked," said Piett, an inventory clerk at Emerson's duty-free store. "But it does affect our town. Some people are very scared of it."

In this paper we describe a Bayesian statistical method designed to infer the magnetic properties of stars observed using high-resolution circular spectropolarimetry in the context of large surveys. This approach is well suited for analysing stars for which the stellar rotation period is not known, and therefore the rotational phases of the observations are ambiguous. The model assumes that the magnetic observations correspond to a dipole oblique rotator, a situation commonly encountered in intermediate- and high-mass stars. Using reasonable assumptions regarding the model parameter prior probability density distributions, the Bayesian algorithm determines the posterior probability densities corresponding to the surface magnetic field geometry and strength by performing a comparison between the observed and computed Stokes V profiles. Based on the results of numerical simulations, we conclude that this method yields a useful estimate of the surface dipole field strength based on a small number (i.e. one or two) of observations. On the other hand, the method provides only weak constraints on the dipole geometry. The odds ratio, a parameter computed by the algorithm that quantifies the relative appropriateness of the magnetic dipole model versus the non-magnetic model, provides a more sensitive diagnostic of the presence of weak magnetic signals embedded in noise than traditional techniques. To illustrate the application of the technique to real data, we analyse seven ESPaDOnS and Narval observations of the early B-type magnetic star LPOri. Insufficient information is available to determine the rotational period of the star and therefore the phase of the data; hence traditional modelling techniques fail to infer the dipole strength. In contrast, the Bayesian method allows a robust determination of the dipole polar strength, G. © 2011 The Authors Monthly Notices of the Royal Astronomical Society © 2011 RAS.

Hydrogen gas is increasingly studied as a potential replacement for fossil fuels because fossil fuel supplies are depleting rapidly and the devastating environmental impacts of their use can no longer be ignored. H2 is a promising replacement energy storage molecule because it has the highest energy density of all common fuels by weight. One area in which replacing fossil fuels will have a large impact is in automobiles, which currently operate almost exclusively on gasoline. Due to the size and weight constraints in vehicles, on board hydrogen must be stored in a small, lightweight system. This is particularly challenging for hydrogen because it has the lowest energy density of common fuels by volume. Therefore, a lot of research is invested in finding a compact, safe, reliable, inexpensive and energy efficient method of H 2 storage. Mechanical compression as well as storage in chemical hydrides and absorption to carbon substrates has been investigated. An overview of all systems including the current research and potential benefits and issue are provided in the present paper. © 2013, Hydrogen Energy Publications, LLC. Published by Elsevier Ltd.

Direct numerical simulation was performed on an incompressible, smooth flat-plate boundary layer at unit molecular Prandtl number and constant surface temperature under free-stream periodically passing turbulent planar wakes over the momentum thickness Reynolds number range of ≤80 Re⊖ ≤1850. This inhomogeneous free-stream wake perturbation source with mean deficit differs markedly from the isotropic turbulent patch used in the previous studies of Wu & Moin (J. Fluid Mech., vol. 630, 2009, p. 5; Phys. Fluids, vol. 22, 2010, 085105). Preponderance of hairpin vortices is observed in both the transitional and turbulent regions of the boundary layer. In particular, the internal structure of merged turbulent spots is a hairpin forest; the internal structure of infant turbulent spots is a hairpin packet. Although more chaotic in the turbulent region, numerous hairpin vortices are readily detected in both the near-wall and outer regions of the boundary layer up to Re = 1850. This suggests that the hairpin vortices in the higher-Reynolds-number region are not simply the aged hairpin forests convected from the upstream transitional region. Temperature iso-surfaces in the companion thermal boundary layer are found to be a useful tracer in identifying boundary-layer hairpin vortex structures. Total shear stress overshoots wall shear stress in the transitional region and the excess relaxes gradually in the downstream turbulent region. This overshoot is shown to be associated with a localized streamwise acceleration of the streamwise velocity component. Breakdown of the wake-perturbed laminar boundary layer is closely related to the formation of hairpin packets out of quasi-streamwise vortices. Mean and second-order statistics are in good agreement with previous data on the standard turbulent boundary layer. Downstream of transition, normalized root-mean-square (r.m.s.) wall-shear-stress intensity shows almost no variation with Re, whereas normalized r.m.s. wall-pressure intensity increases slightly. Taken together with the previous results of Wu & Moin, the generality of the following three phenomena in quasi-standard boundary layers can be reasonably established, namely, preponderance of hairpin vortices in the transitional as well as in the turbulent regions up to Re = 1850, transitional total shear stress overshoot, and a laminar-layer breakdown process closely tied to the formation of hairpin packets. © 2010 Cambridge University Press.

Temperature of water-based substances is investigated by aiming a pulsed CO2 laser beam at the water-air surface. This method of controlling temperature is believed to be flexible in medical applications as it avoids the use of thermal devices, which are often cumbersome and generate rather larger temperature swing with time. The control of temperature in this laser method is modeled by the heat conduction equation. In this investigation, it is assumed that the energy delivered by the CO2 laser is confined within a very thin surface layer of roughly 10 μm. It is shown that the temperature can be very well controlled by a CO2 laser at a steady temperature, and we demonstrate that the method can be adapted to work in tandem with another laser beam. © 2013 Optical Society of America.

Various superimposed chirped relief gratings, acting as diffracting holographic lenses, were photo-inscribed on azo-polymer films upon exposure to the interference pattern of a plane and a curved laser light wavefronts. Depending on the configuration used, this resulted in incident light being focused independently of polarization along the 0th or 1st diffracted order of the grating. The focal point and focalization angle of the resulting holographic lenses were easily tuned during the fabrication process. Furthermore, a dual-focus chirped holographic lens grating was fabricated and shown to exhibit a far-field interference pattern. © 2013 Optical Society of America.

The development of autonomous unmanned aerial vehicles (UAVs) is of high interest to many governmental and military organizations around the world. An essential aspect of UAV autonomy is the ability for automatic path planning. In this paper, we use the genetic algorithm (GA) and the particle swarm optimization algorithm (PSO) to cope with the complexity of the problem and compute feasible and quasi-optimal trajectories for fixed wing UAVs in a complex 3D environment, while considering the dynamic properties of the vehicle. The characteristics of the optimal path are represented in the form of a multiobjective cost function that we developed. The paths produced are composed of line segments, circular arcs and vertical helices. We reduce the execution time of our solutions by using the 'single-program, multiple-data' parallel programming paradigm and we achieve real-time performance on standard commercial off-the-shelf multicore CPUs. After achieving a quasi-linear speedup of 7.3 on 8 cores and an execution time of 10 s for both algorithms, we conclude that by using a parallel implementation on standard multicore CPUs, real-time path planning for UAVs is possible. Moreover, our rigorous comparison of the two algorithms shows, with statistical significance, that the GA produces superior trajectories to the PSO. © 2005-2012 IEEE.

High-quality observations of dark-matter-dominated low surface brightness (LSB) galaxies indicate that, in contrast to the triaxial, centrally concentrated cuspy halos formed in collisionless simulations of halo assembly, these galaxies reside in round, roughly constant density cored halos. In order to reconcile these data with galaxy formation in the context of ΛCDM, processes that alter the shape and density structure of the inner halo are required. We compile observational properties of LSB galaxies to evaluate the plausibility that a previously higher baryonic mass content and feedback from star formation can modify the dark matter halos of these galaxies. We also compare the properties of bulgeless disk galaxies formed in recent simulations to the LSB galaxy sample. We find that observational constraints on LSB galaxy star formation histories, structure, and kinematics make it difficult for baryonic physics to sphericalize and decrease the central density of the dark matter halos of LSB galaxies. © 2011.

Most existing research on parallel cable-driven mechanisms has been performed while neglecting cable mass. However, those prior works that did take cable mass into account have shown that such a hypothesis may lead to significant errors in the analysis of these mechanisms. The research presented herein assesses the effect of neglecting cable mass in the analysis of a spatial parallel three-degree-of-freedom suspended cable-driven mechanism. The analysis is based on the elastic catenary model. The inverse displacement problem of the mechanism is solved numerically subject to constraints on the cable tensions and restrictions on cable drooping. This solution is then used in the numerical estimation of the mechanism workspace. The stiffness of the mechanism is evaluated throughout the workspace by mapping intuitive stiffness indices that are extracted from the stiffness matrix. Both the mechanism workspace and stiffness are found to be heavily influenced by cable sagging. The results obtained in this paper support the notion that the effect of cable sagging on a mechanism should be thoroughly assessed prior to pursuing a design based on the assumption of massless cables. © 2013 Elsevier Ltd.
