description: Die kathetergestützte Aortenklappenimplantation ermöglicht die Versorgung von Patienten mit hochgradiger symptomatischer Aortenklappenstenose bei hohem operativen Risiko. Zugangsweg der Wahl ist die Arteria femoralis, wobei diese anatomisch nicht immer geeignet ist. Ziel dieser Untersuchung war der retrospektive Vergleich des transaortalen und transfemoralen Zugangsweges als primäre Therapie. Zusätzlich wurden transaortale Patienten computertomografisch auf die Möglichkeit des transfemoralen Zugangsweges untersucht. Mit dem Vergleich beider Zugangswege als primäre Therapie zeigte sich eine Unterlegenheit des transaortalen Zugangsweges bezüglich Mortalität und Blutungskomplikation gemäß der Valve Academic Research Consortium 2 Kriterien. Trotz eines höheren operativen Risikos der transfemoralen Patienten, war der transfemorale Zugangsweg mit einer signifikant geringeren Krankenhausmortalität verbunden. Der transfemorale Zugangsweg sollte primär gewählt werden.
description: The transcatheter aortic valve implantation enables the treatment of patients with severe aortic stenosis at high operative risk. The access route of choice is the femoral artery, which is not always anatomically suitable. The aim of this study is the retrospective comparison between the results of the transfemoral and transaortal access route as first-line therapy. In addition, computer tomography images of transaortal patients were reviewed in order to identify the aptitude for transfemoral access. The comparison of both access routes as first-line therapy showed an inferiority of the transaortal access route regarding mortality and bleeding complication according to the Valve Academic Research Consortium 2 criteria. Despite a higher operative risk of transfemoral patients, opting for the transfemoral access route was associated with significantly lower in-hospital mortality. The transfemoral access route should be chosen primarily.

description: Objective:To evaluate the feasibility and effectiveness of the CORDIAL program, a psychosocial intervention consisting of cognitive behavioral therapy (CBT), cognitive rehabilitation, and reminiscence to manage depressive symptoms for people with mild cognitive impairment (MCI) or dementia.Design:We conducted a randomized controlled trial, based on a two-group (intervention and control), pre-/post-intervention design.Setting:Participants were recruited from five different old age psychiatry and memory clinics at outpatients’ hospitals.Participants:Hundred and ninety-eight people with MCI or early-stage dementia were included.Intervention:The intervention group (n= 100) received 11 individual weekly sessions of the CORDIAL program. This intervention includes elements from CBT, cognitive rehabilitation, and reminiscence therapy. The control group (n= 98) received treatment-as-usual.Measurements:We assessed Montgomery–Åsberg Depression Rating Scale (MADRS) (main outcome), Neuropsychiatric Inventory Questionnaire, and Quality of Life in Alzheimer’s disease (secondary outcomes) over the course of 4 months and at a 10-month follow-up visit.Results:A linear mixed model demonstrated that the depressive symptoms assessed by MADRS were significantly more reduced in the intervention groups as compared to the control group (p< 0.001). The effect persisted for 6 months after the intervention. No significant differences between groups were found in neuropsychiatric symptoms or quality of life.Conclusion:Our multicomponent intervention, which comprised 11 individual sessions of CBT, cognitive rehabilitation, and reminiscence therapy, reduced depressive symptoms in people with MCI and dementia.

description: In this paper we study complete manifolds equipped with smooth measures whose spectrum of the weighted Laplacian has an optimal positive lower bound and the $m$-dimensional Bakry-Émery Ricci curvature is bounded from below by some negative constant. In particular, we prove a splitting type theorem for complete smooth measure manifolds that have a finite weighted volume end. This result is regarded as a study of the equality case of an author's theorem (J. Math. Anal. Appl. 361 (2010) 10-18).

Biomimetic grasp planning for cortical control of a robotic hand

description: In this paper we outline a grasp planning system designed to augment the cortical control of a prosthetic arm and hand. A key aspect of this system it the ability to combine online user input and autonomous planning to enable the execution of stable grasping tasks. While user input can ultimately be of any modality, the system is being designed to adapt to partial or noisy information obtained from grasp-related activity in the primate motor cortex. First, principal component analysis is applied to the observed kinematics of physiologic grasping to reduce the dimensionality of hand posture space and simplify the planning task for on-line use. The planner then accepts control input in this reduced-dimensionality space, and uses it as a seed for a hand posture optimization algorithm based on simulated annealing. We present two applications of this algorithm, using data collected from both primate and human subjects during grasping, to demonstrate its ability to synthesize stable grasps using partial control input in real or near-real time.
A battery-less MEMS device for on-demand and controlled drug delivery
Creators: name: Pirmoradi, Fatemeh
Publisher: name: University of British Columbia
Year: 2011

description: Drug therapy efficacy depends on therapeutic concentrations of drugs at disease sites. An ideal controlled and localized drug delivery system would deliver drugs to a target tissue and would locally maintain the required drug concentration. Furthermore, for many diseases, the delivery of therapeutic concentrations on an “on-demand” basis would be of tremendous benefit. In this thesis, a MEMS (Microelectromechanical Systems) based drug delivery device has been developed that provides on-demand release of defined drug quantities. The device consists of a drug-loaded microreservoir that is sealed with an elastic PDMS (polydimethylsiloxane) magnetic membrane with a laser-drilled aperture. The drug release is triggered in the presence of an external magnetic field by deforming the magnetic membrane and therefore discharging the drug solution. The use of magnetic actuation for on-demand and controlled dose sequencing eliminates the need for an on-board power source. A new magnetic membrane material has been developed for the proposed drug delivery device. The polymeric magnetic composites were developed by incorporating coated iron oxide nanoparticles within a PDMS matrix. The new composites show improvement in reducing particle agglomeration compared to existing polymeric magnetic materials. Free-standing PDMS magnetic membranes with a thickness of 35 µm have been fabricated and have shown to deflect in applied magnetic fields. The MEMS drug delivery device has been used to deliver an antiproliferative, taxane-based drug, docetaxel (DTX). On-demand and controlled release of DTX with a dosage suitable for treatment of diabetic retinopathy has been achieved for 35 days. Biological activity of the released DTX was investigated two months after the drug was packaged in the device. These studies confirmed that the antiproliferative effect of DTX can be maintained for 2 months, and the drug does not degrade within the device. This device is a proof-of-concept development for on-demand and controlled delivery of taxane-based agents for treatment of proliferative retinopathy, which requires accurate delivery of nanomolar drug concentrations.

description: We have analysed radial velocity measurements for known transiting exoplanets to study the empirical signature of tidal orbital evolution for close-in planets. Compared to standard eccentricity determination, our approach is modified to focus on the rejection of the null hypothesis of a circular orbit. We are using a MCMC analysis of radial velocity measurements and photometric constraints, including a component of correlated noise, as well as Bayesian model selection to check if the data justifies the additional complexity of an eccentric orbit. We find that among planets with non-zero eccentricity values quoted in the literature, there is no evidence for an eccentricity detection for the 7 planets CoRoT-5b, WASP-5b, WASP-6b, WASP-10b, WASP-12b, WASP-17b, and WASP-18b. In contrast, we confirm the eccentricity of HAT-P-16b, e=0.034\pm0.003, the smallest eccentricity that is reliably measured so far for an exoplanet as well as that of WASP-14b, which is the planet at the shortest period (P=2.24 d), with a confirmed eccentricity, e= 0.088\pm0.003. As part of the study, we present new radial velocity data using the HARPS spectrograph for CoRoT-1, CoRoT-3, WASP-2, WASP-4, WASP-5 and WASP-7 as well as the SOPHIE spectrograph for HAT-P-4, HAT-P-7, TrES-2 and XO-2. We show that the dissipative effect of tides raised in the planet by the star and vice-versa explain all the eccentricity and spin-orbit alignment measurements available for transiting planets. We revisit the mass-period relation (Mazeh et al. 2005, Pont 2011) and consider its relation to the stopping mechanism of orbital migration for hot Jupiters. In addition to CoRoT-2 and HD 189733 (Pont 2009), we find evidence for excess rotation of the star in the systems CoRoT-18, HAT-P-20, WASP-19 and WASP-43.

Banks and banking

description: We assemble bank-level and other data for Fed member banks to model determinants of bank failure. Fundamentals explain bank failure risk well. The first two Friedman-Schwartz crises are not associated with positive unexplained residual failure risk, or increased importance of bank illiquidity for forecasting failure. The third Friedman-Schwartz crisis is more ambiguous, but increased residual failure risk is small in the aggregate. The final crisis (early 1933) saw a large unexplained increase in bank failure risk. Local contagion and illiquidity may have played a role in pre-1933 bank failures, even though those effects were not large in their aggregate impact.

description: In this paper, we study the dynamics of slow oscillations in Purkinje neurons in vitro, and derive a strong association with a forced parametric oscillator model. We demonstrate the precise rhythmicity of the oscillations in Purkinje neurons, as well as a dynamic tunability of this oscillation using a photo-switchable compound. We show that this slow oscillation can be induced in every Purkinje neuron, having periods ranging between 10-25 seconds. Starting from a Hodgkin-Huxley model, we also demonstrate that this oscillation can be externally modulated, and that the neurons will return to their intrinsic firing frequency after the forced oscillation is concluded. These results signify an additional functional role of tunable oscillations within the cerebellum, as well as a dynamic control of a time scale in the brain in the range of seconds.

Dimensionality reduction for hand-independent dexterous robotic grasping

Publisher: name: Columbia University
Year: 2007
Subjects: Robotics

description: In this paper, we build upon recent advances in neuroscience research which have shown that control of the human hand during grasping is dominated by movement in a configuration space of highly reduced dimensionality. We extend this concept to robotic hands and show how a similar dimensionality reduction can be defined for a number of different hand models. This framework can be used to derive planning algorithms that produce stable grasps even for highly complex hand designs. Furthermore, it offers a unified approach for controlling different hands, even if the kinematic structures of the models are significantly different. We illustrate these concepts by building a comprehensive grasp planner that can be used on a large variety of robotic hands under various constraints.

Search for pair production of a new quark that decays to a Z boson and a bottom quark with the ATLAS detector

description: A search is reported for the pair production of a new quark, b', with at least one b' decaying to a Z boson and a bottom quark. The data, corresponding to 2.0 fb^-1 of integrated luminosity, were collected from pp collisions at sqrt(s) = 7 TeV with the ATLAS detector at the CERN Large Hadron Collider. Using events with a b-tagged jet and a Z boson reconstructed from opposite-charge electrons, the mass distribution of large transverse momentum b' candidates is tested for an enhancement. No evidence for a b' signal is detected in the observed mass distribution, resulting in the exclusion at 95% confidence level of b' quarks with masses m_{b'} < 400 GeV that decay entirely via b' to Z+b. In the case of a vector-like singlet b' mixing solely with the third Standard Model generation, masses m_{b'} < 358 GeV are excluded.

description: We present a systematic view planning method to assist construction of 3-D models of large outdoor sites using a mobile robot platform with mounted scanner. In the first stage, we begin with a 2-D site footprint and the planner generates a minimal set of sufficient covering views. These views which incorporate constraints on the scanner, including field of view, minimum and maximum scanning distance, and grazing angle, serve as the initial set of scans which yields an approximate 3-D model of the site. In the second stage, we update this model by using a voxel-based occupancy procedure to plan and acquire the next best view. The algorithm continues to update the model sequentially until an accurate and complete 3-D model is obtained. Results are shown for a segment of the Columbia University campus. The system can also be used as a planning tool for manual construction of 3-D site models.

In this regard, Perry existed as much, and probably more significantly in the minds and hopes of Republican operatives than as an actual candidate.
A virtual reality simulator for the UBC powered upper limb orthosis
Creators: name: Zhao, Jidong
Publisher: name: University of British Columbia
Year: 2011

description: An orthosis, an assistive device to be worn by the user, has been proposed as an option for regaining arm function necessary for performing high priority daily living tasks. Since the 1960s, researchers and engineers have been developing assistive devices in a variety of different forms to help people with weak or flail arms. The goal of the UBC Powered Upper Limb Orthosis (PULO) is to design a highly functional orthotic device to support and restore arm function to one entire arm of a person who has severe weakness or paralysis in both upper limbs. A significant quantity of research work was conducted previously by researchers and students under the supervision of Dr. Douglas Romilly. Currently, a prototype exists, but requires further optimization in both the mechanical and control systems. The objective of this research is to model, test and optimize the current UBC PULO control system via the development of a virtual simulator. To accomplish this goal, required tasks include software selection, Simulink-based modeling of the current control system, physical modeling of the mechanical component and creation of a virtual scene. The developed simulator allows the user to provide input commands through the newly developed user interface devices, with the output motion of the prototype orthosis displayed in a Virtual Reality (VR) environment. The specifically designed simulation has indicated a high level of potential suitability of using the virtual simulator for testing and optimizing the current control system, screening and training of potential users for the UBC PULO.

description: The efficiency of dynamical decoupling pulse sequences in removing noise due to a charge fluctuator is studied for a singlet-triplet spin qubit. We develop a numerical method to solve the dynamical equations for all three components of the Bloch vector under a general pulse protocol, and with an arbitrary rotation axis. The qubit is shown to undergo both dephasing and dissipative dynamics, pending on its working point. Analytical solutions are found for the limits of weakly and strongly coupled fluctuators, shedding light on the distinct dynamics in the different parameter regimes. Scaling of the qubit decay time with the number of control pulses is found to follow a power law over a wide range of TLF parameters and qubit bias points.

description: The widespread use of mobile computing and telecommuting has increased the need for effective protection of computing platforms. Traditional schemes that involve strengthening the security of individual systems, or the use of firewalls at network entry points have difficulty accommodating the special requirements of remote and mobile users. We propose the use of a special purpose drop-in firewall/VPN gateway called Sieve, that can be inserted between the mobile workstation and the network to provide individualized security services for that particular station. Sieve is meant to be used like an external modem: the user only needs to plug it in. Its existence is transparent to the user, requiring no modification to the workstation configuration. To function in this role, Sieve has been designed to be compact, low-cost, requiring little administration or maintenance. In this paper, we discuss the features and advantages of our system. We demonstrate how Sieve was used in various application areas (home, university environment, etc.) and describe our future plans.

Life under the "new normal": notes on the future of preparedness

description: Being prepared for emergencies is not a new concept. At every level of government there are contingency plans for natural disasters, accidental catastrophes, local events and personal emergencies of every conceivable manner. Organizations from the Red Cross to the Federal Emergency Management Agency to hospital emergency departments are in a constant state of readiness. Often, regionally specific plans are in place based on expectations of particular kinds of disasters: earthquakes in the West, hurricanes on the East Coast, and tornados in the Midwest. In fact, long before 9/11, even terrorism had been on the minds of at least a handful of stalwart preparedness experts – mostly in the military and in special governmental agencies (Benjamin & Simon, 2002; Stern, 2003; Clarke, 2004).
The chapters in this volume survey the state of our understanding of the psychological response to terrorism and other exigent events. It is clear that much has been learned. At the same time, many questions remain. What are the best interventions post-event? How do we recognize those in most immediate need, or those who may be most susceptible, other than those with pre-existing psychopathology? (North et al. this volume). What sorts of pre-event messages are the most useful for preparing the community?

description: Choroideremia (CHM) is a rare X-linked chorioretinal dystrophy affecting the photoreceptors, retinal pigment epithelium (RPE) and choroid, however, the involvement of the choroid in disease progression is not fully understood. CHM is caused by mutations in the CHM gene, encoding the ubiquitously expressed Rab escort protein 1 (REP1). REP1 plays an important role in intracellular trafficking of vesicles, including melanosomes. In this study, we examined the ultrastructure of the choroid in chmru848 fish and Chmnull/WT mouse models using transmission electron and confocal microscopy. Significant pigmentary disruptions were observed, with lack of melanosomes in the choroid of chmru848 fish from 4 days post fertilisation (4dpf), and a reduction in choroidal blood vessel diameter and interstitial pillars suggesting a defect in vasculogenesis. Total melanin and expression of melanogenesis genes tyr, tryp1a, mitf, dct and pmel were also reduced from 4dpf. In Chmnull/WT mice, choroidal melanosomes were significantly smaller at 1 month, with reduced eumelanin at 1 year. The choroid in CHM patients were also examined using spectral domain optical coherence tomography (SD-OCT) and OCT-angiography (OCT-A) and the area of preserved choriocapillaris (CC) was found to be smaller than that of overlying photoreceptors, suggesting that the choroid is degenerating at a faster rate. Histopathology of an enucleated eye from a 74-year-old CHM male patient revealed isolated areas of RPE but no associated underlying CC. Pigmentary disruptions in CHM animal models reveal an important role for REP1 in melanogenesis, and drugs that improve melanin production represent a potential novel therapeutic avenue.
Data acquisition and view planning for 3-D modeling tasks

Year: 2007
Subjects: Artificial intelligence

description: In this paper we address the joint problems of automated data acquisition and view planning for large-scale indoor and outdoor sites. Our method proceeds in two distinct stages. In the initial stage, the system is given a 2-D map with which it plans a minimal set of sufficient covering views. We then use a 3-D laser scanner to take scans at each of these views. When this planning system is combined with our mobile robot, it automatically computes and executes a tour of these viewing locations and acquires the views with the robot's onboard laser scanner. These initial scans serve as an approximate 3-D model of the site. The planning software then enters a second stage in which it updates this model by using a voxel-based occupancy procedure to plan the next best view. This next best view is acquired, and further next best views are sequentially computed and acquired until a complete 3-D model is obtained. Results are shown for Fort Jay on Governors Island in the City of New York and for the church of Saint Menoux in the Bourbonnais region of France.

description: A class of theories of gravity based on a Lagrangian which depends on the curvature and metric - but not on the derivatives of the curvature tensor - is of interest in several contexts including in the development of the paradigm that treats gravity as an emergent phenomenon. This class of models contains, as an important subset, all Lanczos-Lovelock models of gravity. I derive several identities and properties which are useful in the study of these models and clarify some of the issues that seem to have received insufficient attention in the past literature.

Marginal Tax Rate Cuts and the Public Tax Debate

description: During the course of the public policy debate concerning the likely economic impact of EGTRRA (The Economic Growth and Tax Relief Reconciliation Act of 2001), very little reference was made to the public finance literature concerning the likely impact of marginal tax rate reductions. Instead, proponents of the bill, like the president himself, argued that the reduction in revenue was advisable because it would lower the growth of government spending. Opponents of the bill chose to emphasize two effects of the bill. First, they argued that the bill benefited the wealthy disproportionately, and they connected the reduction in the budget surplus that would result from the decline in revenue to long-term interest rates, arguing that the increase in rates would offset any gains that the marginal rate reductions might provide.
