description: Hake is the most valuable fisheries species in South Africa, with an estimated landed value of R658 million in 1997. The fishery is presently managed under an individual quota system, where total allowable catch (TAC) is set annually and divided up amongst quota holders according to past performance, without quota holders having to pay for it. Fundamental restructuring of the South African hake quota market is however due to take place in the near future as recommended by the White Paper on Marine Fisheries Policy (1997). Factor analysis of data collected from a postal survey of existing South African hake quota holders and rejected hake quota applicants suggests that distinct differences in attitudes towards restructuring exist amongst respondents. Four factors, representing groups of respondents defined as (1) applicants, (2) quota holders, (3) small scale respondents (comprising of both applicants and quota holders), and (4) larger, longer established quota holders, sharing similar attitudes towards restructuring were extracted. It was also calculated that a substantial annual rent of approximately R279 million is generated by the South African hake industry, which is presently harvested free of charge by those issued with quota. It is stated policy of the White Paper to capture these rents, however methods of accomplishing this have not been well accepted by the industry. This study aims at providing some solutions to these problems of restructuring.

description: The complete next-to-next-to leading order (NNLO) QCD correction has been studied to the di-lepton invariant mass distribution within the Randall-Sundrum (RS) framework. In addition, the soft-virtual (SV) cross-section at next-to-next-to-next-to leading order (N$^3$LO) as well as threshold resummation to next-to-next-to leading logarithms (NNLL) level have been presented. The analytical coefficient for SV production has been obtained up to three loops very recently along with the process-dependent coefficients needed to perform resummation up to NNLL. These coefficients are universal for any universal spin-2 model where spin-2 particle couples to the Standard Model (SM) particles with equal strength. We use these coefficients in predicting N$^3$LO SV results as well as matched NNLO+NNLL results for invariant mass distribution for Drell-Yan (DY) production in RS model. We performed a detailed phenomenological analysis and present prediction for the 13 TeV centre-of-mass energy at the Large Hadron Collider (LHC) for the search of such RS Kaluza-Klein (KK) resonances. The NNLO cross-section adds about $21\%$ correction to the next-to-leading order (NLO) results. We found that the SV correction at the N$^3$LO order decreases the cross-section by $0.7\%$ near the first KK resonance ($M_1=1500$ GeV) whereas the resummed result shows an increment over NNLO by $7\%$ of LO. We performed a detailed analysis including scale variation and parton distribution function (PDF) variations. These new results provide an opportunity to stringently constrain the parameters of the model in particular in the search of heavy spin-2 resonances at the LHC.

description: We estimate the merger timescale of spectroscopically-selected, subparsec supermassive black hole binary (SMBHB) candidates by comparing their expected contribution to the gravitational wave background (GWB) with the sensitivity of current pulsar timing array (PTA) experiments and in particular, with the latest upper limit placed by the North American Nanohertz Observatory for Gravitational Waves (NANOGrav). We find that the average timescale to coalescence of such SMBHBs is $\langle t_{\rm evol} \rangle > 6\times 10^4\,$yr, assuming that their orbital evolution in the PTA frequency band is driven by emission of gravitational waves. If some fraction of SMBHBs do not reside in spectroscopically detected active galaxies, and their incidence in active and inactive galaxies is similar, then the merger timescale could be $\sim 10$ times longer, $\langle t_{\rm evol} \rangle > 6\times 10^5\,$yr. These limits are consistent with the range of timescales predicted by theoretical models and imply that all the SMBHB candidates in our spectroscopic sample could be binaries without violating the observational constraints on the GWB. This result illustrates the power of the multi-messenger approach, facilitated by the PTAs, in providing an independent statistical test of the nature of SMBHB candidates discovered in electromagnetic searches.

description: In Sub-Saharan Africa food security will remain a major issue as cereals production is decreasing and their import prices are increasing. If food security involves food availability, accessibility, stability and the utilization of food in a nutritious manner by households, it is important to examine food production stability and consumption diversification as important determinants of food security. This paper examines these relationships in the UEMOA countries. The results indicate relatively stable food productions and weak consumption diversification. As a result the food security levels in the union are overall moderate or low. Thus agricultural policies should focus on existing and potential opportunities that enhance food production and consumption diversification and competitiveness in the Union.

Each result reflects the mean outcome of 1000 models based on 1000 randomly selected grid cell data points that include an exponential spatial covariance structure. The mean slope indicates by how many species a given group generally increases per unit increase in excavator richness and the mean Spearman rho is a measure of the strength of the relationships.

description: Atomic and molecular data for the transitions of a number of astrophysically interesting species are summarized, including energy levels, statistical weights, Einstein A-coefficients and collisional rate coefficients. Available collisional data from quantum chemical calculations and experiments are extrapolated to higher energies. These data, which are made publically available through the WWW at http://www.strw.leidenuniv.nl/~moldata, are essential input for non-LTE line radiative transfer programs. An online version of a computer program for performing statistical equilibrium calculations is also made available as part of the database. Comparisons of calculated emission lines using different sets of collisional rate coefficients are presented. This database should form an important tool in analyzing observations from current and future (sub)millimetre and infrared telescopes.

description: A rigid-flexible manipulator may be assigned tasks in a moving environment where the winds or vibrations affect the position and/or orientation of surface of operation. Consequently, losses of the contact and perhaps degradation of the performance may occur as references are changed. When the environment is moving, knowledge of the angle α between the contact surface and the horizontal is required at every instant. In this paper, different profiles for the time varying angle α are proposed to investigate the effect of this change into the contact force and the joint torques of a rigid-flexible manipulator. The coefficients of the equation of the proposed rotating surface are changing with time to determine the new X and Y coordinates of the moving surface as the surface rotates.
Monopole versus spherical harmonic superconductors: Topological repulsion, coexistence and stability

description: The monopole harmonic superconductor (SC), proposed in doped Weyl semimetals as a pairing between the Fermi surfaces enclosing the Weyl points, is rather unusual, as it features the monopole charge inherited from the parent metallic phase. However, this state can compete with more conventional spherical harmonic pairings, such as an $s$-wave. We here demonstrate, within the framework of the weak coupling mean-field BCS theory, that the monopole and a conventional spherical harmonic SC quite generically coexist, while the repulsion can take place when the absolute value of the monopole charge matches the angular momentum quantum number of the spherical harmonic. As we show, this feature is a direct consequence of the topological nature of the monopole SC, and we dub it \emph{topological repulsion}. We illustrate the above principle with the example of the conventional $s-$ and $(p_x\pm ip_y)-$wave pairings competing with the monopole SC $Y_{-1,1,0}(θ,ϕ)$, which coexist in a finite region of the parameter space, and repel, respectively. Furthermore, the s-wave pairing is more stable both when the chemical potentials at the nodes are unequal, and in the presence of point-like charged impurities. Since the phase transition is discontinuous, close to the phase boundary, we predict that the Majorana surface modes at the interfaces between domains featuring the monopole and the trivial phases, such as an $s-$wave, will be the experimental signature of the monopole SC.

Exploring indigenous approaches to women’s well-being in Viet Nam : negotiating gender
Creators: name: Nguyen, Julie H.D.T.
Publisher: name: University of British Columbia
Year: 2009

description: Using an interdisciplinary approach, this dissertation focuses on the cultural aspects of women's well-being in Viet Nam in the context of achieving more effective and equitable human development. The concept of culture refers to the traditions, which have been formed and transformed over thousands of years, and which are mainly characterized by the intertwining of conflicting doctrines of indigenous culture. This study seeks to: (a) describe some of the major historical and cultural factors affecting gender relations; (b) examine the effectiveness of national and international efforts in negotiating and adapting to the gender and development approach; and (c) evaluate the implications of current socio-economic and cultural changes for the future well-being of women and female children. Using qualitative and quantitative methods in a variety of approaches, including a review of Vietnamese primary sources, policy documents and a case study of a suburban commune, the thesis reaches five main conclusions. First, Viet Nam encounters certain difficulties in achieving women's emancipation, which stems from its historical, cultural and political context that requires a concerted effort to negotiate and adapt to the prevalent theories relating to the gender and development approach. Second, although there remain considerable negative impacts of traditional norms and practices on women, there are also tremendously positive aspects of equality and social cohesion in these traditions. Therefore, a balanced and thorough analysis is necessary in order to identify suitable and effective intervention measures. Third, with the recent đổi mới (renovation) policies, the promotion of gender equity has met with a certain degree of success, but apparently is still significantly constrained by the persistence of social and cultural norms that create continual obstacles to gender equality. Fourth, the dynamics of changes in gender relations at local levels reveal that women are often left in more vulnerable positions in terms of receiving lower benefits achieved at higher cost and sacrifice. Fifth, policy prescriptions regarding women's wellbeing will require a consideration of material and non-material aspects of their relative situation, an appreciation of both modern and traditional values, and a realistic and sensitive approach in making proposals for their reform and modification.

description: The modification of the boundary condition for polyelectrolyte adsorption on charged surface with short-ranged interaction is investigated under two regimes. For weakly charged Gaussian polymer in which the short-ranged attraction dominates, the boundary condition is the same as that of the neutral polymer adsorption. For highly charged polymer (compressed state) in which the electrostatic interaction dominates, the linear relationship (electrostatic boundary condition) between the surface monomer density and the surface charge density needs to be modified.

description: We explore packet traffic dynamics in a data network model near phase transition point from free flow to congestion. The model of data network is an abstraction of the Network Layer of the OSI (Open Systems Interconnection) Reference Model of packet switching networks. The Network Layer is responsible for routing packets across the network from their sources to their destinations and for control of congestion in data networks. Using the model we investigate spatio-temporal packets traffic dynamics near the phase transition point for various network connection topologies, and static and adaptive routing algorithms. We present selected simulation results and analyze them.

description: The analyses of sunspot observations revealed a fundamental magnetic property of the umbral boundary, the invariance of the vertical component of the magnetic field. We aim to analyse the magnetic properties of the umbra-penumbra boundary in simulated sunspots and thus assess their similarity to observed sunspots. Also, we aim to investigate the role of plasma $β$ and the ratio of kinetic to magnetic energy in simulated sunspots on the convective motions. We use a set of non-grey simulation runs of sunspots with the MURaM code. These data are used to synthesise the Stokes profiles that are then degraded to the Hinode spectropolarimeter-like observations. Then, the data are treated like real Hinode observations of a sunspot and magnetic properties at the umbral boundaries are determined. Simulations with potential field extrapolation produce a realistic magnetic field configuration on their umbral boundaries. Two simulations with potential field upper boundary, but different subsurface magnetic field structures, differ significantly in the extent of their penumbrae. Increasing the penumbra width by forcing more horizontal magnetic fields at the upper boundary results in magnetic properties that are not consistent with observations. This implies that the size of the penumbra is given by the subsurface structure of the magnetic field. None of the sunspot simulations is consistent with observed properties of the magnetic field and direction of the Evershed flow at the same time. Strong outward directed Evershed flows are only found in setups with artificially enhanced horizontal component of the magnetic field at the top boundary that are not consistent with the observed magnetic field properties at the UP boundary. We want to stress out that the `photospheric' boundary of simulated sunspots is defined by a magnetic field strength of equipartition field value.
Core excitation in Ozone localized to one of two symmetry-equivalent chemical bonds - molecular alignment through vibronic coupling

description: Core excitation from terminal oxygen O$_T$ in O$_3$ is shown to be an excitation from a localized core orbital to a localized valence orbital. The valence orbital is localized to one of the two equivalent chemical bonds. We experimentally demonstrate this with the Auger Doppler effect which is observable when O$_3$ is core-excited to the highly dissociative O$_{T}$1s$^{-1}$7a$_1^1$ state. Auger electrons emitted from the atomic oxygen fragment carry information about the molecular orientation relative to the electromagnetic field vector at the moment of excitation. The data together with analytical functions for the electron-peak profiles give clear evidence that the preferred molecular orientation for excitation only depends on the orientation of one bond, not on the total molecular orientation. The localization of the valence orbital "7a$_1$" is caused by mixing of the valence orbital "5b$_2$" through vibronic coupling of anti-symmetric stretching mode with b$_2$-symmetry. To the best of our knowledge, it is the first discussion of the localization of a core excitation of O$_3$. This result explains the success of the widely used assumption of localized core excitation in adsorbates and large molecules.

It is the only meter class optical research facility at this southern latitude between the east coast of Australia and South Africa and can rapidly image optical transients at a longitude not monitored by other similar facilities. We review here the main results achieved during the last decade and give some points toward the goals set for future years. Finally we discuss the modifications and improvements we had to perform in the facility to reach these new goals.

description: One of the major and widely known small scale problem with the Lambda CDM model of cosmology is the core-cusp problem. In this study we investigate whether this problem can be resolved using bar instabilities. We see that all the initial bars are thin (b/a $$ 0.3$) faster in the high resolution simulations. By increasing the resolution, we mean a larger number of disk particles. The thicker bars in the high resolution simulations transfer less angular momentum to the halo. Hence, we find that in the high resolution simulations it takes around 7 Gyr for the bar to remove inner dark matter cusp which is too long to be meaningful in galaxy evolution timescales. Physically, the reason is that as the resolution increases, the bar buckles faster and becomes thicker much earlier on.

description: Various institutions wanting to invest in agricultural production or the agribusiness sector in the SADC region need information on the quality and location of agricultural resources. Generating agricultural resource information on a regional level provides the challenge of integrating vast amounts of information from the various countries, implying storing, retrieving and manipulating it to determine areas best suited to grow a particular crop; or various crops that can be grown in a particular area. A Geographical Information System (GIS) has been developed as part of a broader project to assess the agricultural potential of SADC countries from a physical-biological-climatological point of view. Crop suitability maps obtained from the GIS containing information on resource quality, combined with transport modelling to add information on transport cost, can be used by private sector institutions for location decisions and the public sector for planning the provision of physical and social infrastructure. Incorporating resource data of the whole region implies that the available data on the climate, topography and soils of most of the SADC countries is coarse which only allows analyses on a national and regional level.

description: Natural hyperbolic two-dimensional systems are a fascinating class of materials that could open alternative pathways to the manipulation of plasmon propagation and light-matter interactions. Here, we present a comprehensive study of the optical response in T$_d\,$-WTe$_2$ by means of density-functional and many-body perturbation theories. We show how monolayer WTe$_2$ with in-plane anisotropy sustains hyperbolic plasmon polaritons, which can be tuned via chemical doping and strain. The latter is able to extend the hyperbolic regime toward the near infrared with low losses. Moreover, with a moderate strain, WTe$_2$ can even be switched between elliptic and hyperbolic regimes. In addition, plasmons in WTe$_2$ are characterized by low losses owing to electron-phonon scattering, which is responsible for the temperature dependence of the plasmon line width. Interestingly, the temperature can also be utilized to tune the in-plane anisotropy of the WTe$_2$ optical response.

description: We present exact theoretical results about energetic and dynamic properties of a spinless charged quantum particle on the Euclidean plane subjected to a perpendicular random magnetic field of Gaussian type with non-zero mean. Our results refer to the simplifying but remarkably illuminating limiting case of an infinite correlation length along one direction and a finite but strictly positive correlation length along the perpendicular direction in the plane. They are therefore ``random analogs'' of results first obtained by A. Iwatsuka in 1985 and by J. E. Müller in 1992, which are greatly esteemed, in particular for providing a basic understanding of transport properties in certain quasi-two-dimensional semiconductor heterostructures subjected to non-random inhomogeneous magnetic fields.

description: The authors propose the implementation of hybrid Fuzzy Logic-Genetic Algorithm (FL-GA) methodology to plan the automatic assembly and disassembly sequence of products. The GA-Fuzzy Logic approach is implemented onto two levels. The first level of hybridization consists of the development of a Fuzzy controller for the parameters of an assembly or disassembly planner based on GAs. This controller acts on mutation probability and crossover rate in order to adapt their values dynamically while the algorithm runs. The second level consists of the identification of theoptimal assembly or disassembly sequence by a Fuzzy function, in order to obtain a closer control of the technological knowledge of the assembly/disassembly process. Two case studies were analyzed in order to test the efficiency of the Fuzzy-GA methodologies.

description: The complexity of a neuronal cell shape is known to be related to its function. Specifically, among other indicators, a decreased complexity in the dendritic trees of cortical pyramidal neurons has been associated with mental retardation. In this paper we develop a procedure to address the characterization of morphological changes induced in cultured neurons by over-expressing a gene involved in mental retardation. Measures associated with the multiscale connectivity, an additive image functional, are found to give a reasonable separation criterion between two categories of cells. One category consists of a control group and two transfected groups of neurons, and the other, a class of cat ganglionary cells. The reported framework also identified a trend towards lower complexity in one of the transfected groups. Such results establish the suggested measures as an effective descriptors of cell shape.

description: In Namibia historically high levels of support to the commercial farm sector have been reduced in recent years in line with general market liberalisation trends. However some support remains. At the same time more attention has been paid to supporting the previously neglected communal sector. The avowed aim of politicians is to ensure that grain producers in Namibia operate “on a level playing field”. This paper examines to what extent the policy support playing field has been levelled for all major types of grain producer in Namibia. A methodology is introduced for developing a common measure of the effects of price support across grain producers with subsistence and commercial objectives and across scales of operation ranging from 1 hectare to 300 hectares under grain crops. The finding show that the bulk of grain producers in Namibia, who farm most of the grain area, remain seriously disadvantaged compared to the fewer, larger farms. Ongoing discussions on outsourcing government support services to small farmers is likely to result in the playing field becoming more uneven and other compensating measures will need to be taken if politicians and decision makers are serious about “evening the playing field for all”.

description: The next Round of multilateral negotiations is due to commence in 1999. Countries have already learned a lot from the shortcomings of the previous agricultural negotiations in the implementation of the agriculture negotiations and in the Analysis and Information Exchange meetings since 1997. The ministerial meeting of developed countries (OECD), has revealed that their future development of agricultural policy has changed little as a result of policy changes in the 1990s. In the next Round the EU is expected to be mainly on the defensive to try and maintain subsidy provisions. The main players that are expected to fuel the upcoming negotiations are the Cairns Group of agricultural export countries as well as the United States. The main task of reformers would be related to substantial further reduction of distortive trade measures, the covering of matters left unresolved in the Uruguay Round and to close the loopholes of the previous agreement. In general, reformers would like to push for a fairer system with more equal benefits to all.

description: They are few the rakes of the country that have the modern technology and the personnel qualified to carry out the humanitarian sacrifice as it indicates it the Federal Law of Animal Sanity. (DOF. 23-July-2007). Really the only dependence or association that he/she has had interest and he/she has been in charge of seriously of supervising that the slaughter is carried out in a humanitarian way, it is the denominated civil association ANPALPA A.C (National Association for the Application of Laws of Protection to the Animals) that has taken the initiative to introduce the methods of humanitarian sacrifice in near 400 rakes and slaughterhouses of the country; and it is unlikely that the corresponding authorities (SAGARPA and HEALTH), have not taken the responsibility properly of continuing with this work begun by ANPALPA for 30 years, since finally to the authority it corresponds him to assist this problematic one and not to the civil society, like it has been happening so far. It was scientifically proven that, to better treatment and good handling of the animals dedicated to the sacrifice, less estrés, smaller loss of weight will be caused and it will be obtained better quality and bigger quantity of the products meat resultants. Difference should not exist among the rakes TIF (Type Federal Inspection) and the municipal rakes or the matters, in the concerning thing to good facilities, modern technology, sacrifice methods, qualified personnel, sanitary supervision, I manage hygienic of the products and combat to the produced contamination, since the obtained products, they are dedicated for human consumption and its quality and hygiene they should be conscientiously revised in any slaughter center, call you TIF, municipal or matter. The only difference that it should exist among the rakes TIF and the municipal ones, it resides in the size of the facilities, same that should be according to the quantity of animals sacrificed daily, but not in the technology and functionality of the facilities, as well as in the personnel's training that there works. He/she intended the innovation of establishing a stamp of guarantee of humanitarian sacrifice, with that which the consumer can be sure that the meat product that will buy, comes from animals that were sacrificed with the humanitarian methods of previous desensitization, to avoid to the maximum the suffering of the animals. This stamp can be additional to that of the sanitary inspection.

Factorization Properties in the 3D Edwards-Anderson Model

description: Starting from the study of a linear combination of multi-overlaps which can be rigorously shown to vanish for large systems we numerically analyze the factorization properties of the link-overlaps multi-distribution for the 3D Gaussian Edward-Anderson spin-glass model. We find evidence of a pure factorization law for the multi-correlation functions. For instance the quantity [ - ]/ tends to zero at increasing volumes. We also perform the same analysis for the standard overlap for which instead the lack of factorization persists increasing the size of the system. The necessity of a better understanding of the mutual relation between the two overlaps is pointed out.

Aligned CP-violating Higgs sector canceling the electric dipole moment

description: We discuss the effect of CP violation in the aligned scenario of the general two-Higgs-doublet model, in which the Higgs potential and the Yukawa interaction provide additional CP-violating phases. An alignment is imposed to the Yukawa interaction in order to avoid dangerous flavor changing neutral currents. The Higgs potential is also aligned such that the coupling constants of the lightest Higgs boson, which is identified as the discovered Higgs boson with the mass of 125 GeV, are the same as those of the standard model. In general, CP-violating phases originated by the Yukawa interaction and the Higgs potential are strongly constrained by the current data for the electric dipole moment (EDM). It is found that in our scenario contributions from the two sources of CP violation can be destructive and consequently their total contribution can satisfy the EDM results, even when each CP-violating phase is large. Such a large CP-violating phase can be tested at collider experiments by looking at the angular distributions of particles generated by the decays of the additional Higgs bosons.

title: American Diplomacy Toward China, 1945-1948
Creators: name: Horner, Margo E.
Publisher: name: Old Dominion University Libraries
Year: 1973

description: America's relationship toward China during the postwar years was aptly described by President Truman's summary of his China policy: “The role of this government in its relations with China has been subjected to considerable misrepresentation, distortion, and misunderstanding. Some of these attitudes arose because this government was reluctant to reveal certain facts…."8 Admiral William Leahy, Chief of Staff to presidents Roosevelt and Truman, acknowledged that America’s “post-war attitude toward the Government of China is completely beyond understanding.”9 This writer shares these beliefs and deems it necessary to reexamine the context of the historical developments within which American policy was formulated from the postwar years of 1945 through 1948 in order to prove that this misrepresentation, distortion and misunderstanding existed. Emphasis is placed on the role of the Department of State, including the reports of foreign service officers, the President, the Congress, American and Chinese correspondents, Chinese Nationalist and Communist representatives, all of whom surveyed the situation in China and helped to form and shape our China policy.

The first chapter of this paper will consist of an examination of America's China policy and the alternatives to that policy. The second chapter will analyze Ambassador Hurley's resignation and the ensuing congressional hearings. The third chapter will focus on the appointment of General George C. Marshall as the President’s Special Representative to China and will examine the directives which Marshall carried with him to China, as well as the possibility of coalition government in China. The fourth chapter will scrutinize the thirteen-month Marshall Mission and the release of Marshall's farewell statement at the time of his departure from China. The fifth chapter will analyze the beginning of the end to bipartisan support for the Administration’s China policy, the termination of the ten-month embargo, Wedemeyer’s trip to China and his report. The sixth chapter will reveal the height of Republican criticism and the resulting China Aid Act.

description: Density matrix renormalization group (DMRG) is applied to a (1+1)-dimensional $λϕ^4$ model to study spontaneous breakdown of discrete $Z_2$ symmetry numerically. We obtain the critical coupling $(λ/μ^2)_{\rm c}=59.89\pm 0.01$ and the critical exponent $β=0.1264\pm 0.0073$, which are consistent with the Monte Carlo and the exact results, respectively. The results are based on extrapolation to the continuum limit with lattice sizes $L=250,500$, and 1000. We show that the lattice size L=500 is sufficiently close to the the limit $L\to\infty$ \cite{Sugihara:2004qr}.

How the common lidar data format improved our data processing routine

description: In 2018 DTU, Fraunhofer IEE and others published the report from their e-WindLidar project (https://doi.org/10.5281/zenodo.2478051) in which they introduced a common format for wind lidars. Up to now, lidars from different manufacturers spit out data in different formats using different variables. In Stuttgart we therefore developed different code for each lidar in order to process the data. The common format brings only advantages: in Stuttgart we implemented it in our code and now only have one data processing routine for different lidar systems. Collaboration is facilitated because exchange of code and data is very easy. Interfaces where data is exchanged are clearly defined. Therefore we believe that the common data format is the basis for a digitized lidar infrastructure of the future. This presentation was given at the IEA Wind Task 32 Workshop on Digitalization of Wind Lidar on March 17th, 2021
Robotic Applications in Cardiac Surgery

description: Traditionally, cardiac surgery has been performed through a median sternotomy, which allows the surgeon generous access to the heart and surrounding great vessels. As a paradigm shift in the size and location of incisions occurs in cardiac surgery, new methods have been developed to allow the surgeon the same amount of dexterity and accessibility to the heart in confined spaces and in a less invasive manner. Initially, long instruments without pivot points were used, however, more recent robotic telemanipulation systems have been applied that allow for improved dexterity, enabling the surgeon to perform cardiac surgery from a distance not previously possible. In this rapidly evolving field, we review the recent history and clinical results of using robotics in cardiac surgery.
