title: The role of peer-facilitated reflection in critical incident analysis amongst physical therapist assistant students
Creators: name: Thompson, I
Publisher: name: University of Liverpool Repository
Year: 2018

description: This research examines the role that peer-facilitated reflection (PFR) plays in influencing the abilities of physical therapist assistant (PTA) students to cope with critical incidents in their academic and clinical coursework. Physical therapist assistants are expected to possess well-developed critical thinking abilities upon graduation that will guide them through professional practice. Several scholars contend that critical thinking abilities should be developed within the curriculum, and that they are best cultivated through reflective practice. However, traditional modes of curricular-based reflective practice have come under scrutiny, revealing shortcomings in their efficacy. These include: a theory-practice gap, ineffective facilitation, and deficient models of assessment. Consequently, a model of PFR was proposed as a more utile reflective approach to develop critical thinking amongst PTA students. An interpretivist investigation was carried out through an action research methodology using Flanagan’s critical incident technique, which favors reflection and planning based upon a significant event. Peer-reflective discussions were implemented into the curriculum of a PTA program. Student participants collectively reflected and developed action plans to put into practice. Data gleaned from post-discussion interviews and questionnaires was examined in light of the criticisms levied against reflective practice and was used to determine the effectiveness of the PFR approach. Findings indicated that students viewed PFR positively, and that they felt the discussion helped them cope with challenges confronted in their academic program. Observational analysis revealed challenges with facilitating reflective discussions, such as having faculty present and keeping discussions focused. Ameliorating steps were implemented for subsequent The Role of Peer-Facilitated Reflection iv discussions that removed faculty from the reflective process and that trained students to effectively lead their own discussions. An assessment model was adapted for this study that examined outcomes based upon the students’ own assessments. Though still in its development, it offers promise as a means for faculty and students to interpret the efficacy of reflective approaches. Finally, study findings informed practice recommendations for the implementation of pedagogical PFR in an academic PTA program. These include affording flexibility for discussion topics, conducting student-led discussions, managing discussion frequency and group composition, and encouraging faculty participation.

description: Analysis of the Cassini Ultraviolet Imaging Spectrometer (UVIS) stellar and solar occultations at Titan to date include 12 species: N$_{2}$ (nitrogen), CH$_{4}$ (methane), C$_{2}$H$_{2}$ (acetylene), C$_{2}$H$_{4}$ (ethylene), C$_{2}$H$_{6}$ (ethane), C$_{4}$H$_{2}$ (diacetylene), C$_{6}$H$_{6}$ (benzene), C$_{6}$N$_{2}$ (dicyanodiacetylene), C$_{2}$N$_{2}$ (cyanogen), HCN (hydrogen cyanide), HC$_{3}$N (cyanoacetylene), and aerosols distinguished by a structureless continuum extinction (absorption plus scattering) of photons in the EUV. The introduction of aerosol particles, retaining the same refractive index properties as tholin with radius $\sim$125 Åand using Mie theory, provides a satisfactory fit to the spectra. The derived vertical profile of aerosol density shows distinct structure, implying a reactive generation process reaching altitudes more than 1000 km above the surface. A photochemical model presented here provides a reference basis for examining the chemical and physical processes leading to the distinctive atmospheric opacity at Titan. We find that dicyanodiacetylene is condensable at $\sim$650 km, where the atmospheric temperature minimum is located. This species is the simplest molecule identified to be condensable. Observations are needed to confirm the existence and production rates of dicyanodiacetylene.

Closed loop end piece control of a servo controlled manipulator
Creators: name: Boucher, Daniel Charles
Publisher: name: University of British Columbia
Year: 2010

description: This thesis discusses the possibility of attaining closed loop end piece control of a servo controlled manipulator by externally modifying the independent control loop set point of each robot link. This procedure leaves the existing servo control loops intact and thus has the benefit of acquiring the advantages of an advanced control strategy while retaining the inherent reliability and stability of the existing control loops. Algorithms are proposed for compensating for known disturbance torques, eliminating end piece position errors, and applying specified forces to the surroundings with the end piece. These algorithms are demonstrated for the three degree of freedom case using a simulation package ROBSIM.FOR which simulates the response of a servo controlled manipulator to set point inputs. To compensate for known disturbance torques the torques generated by the robot control system are assumed to be directly proportional to the changes in set points. These approximate relations are used to estimate the adjustment in set points necessary to generate the required additional joint torques. Simulation results show that this method is effective in compensating for gravity disturbance torques. The Jacobian relates changes in position of the end piece to changes in joint angles. Using the Jacobian combined with a weighting factor to prevent overshoot an algorithm is developed which drives end piece position errors to zero. The transpose of the Jacobian is used to relate forces exerted on the surroundings by the end piece to generated joint torques. The required torques are created by adjusting the set points. Simulation results indicate that this method can be used to exert specified forces. Force control is more difficult to achieve than position control because the robot interacts physically with its surroundings. The ability of the robot to exert forces depends strongly on the robot's configuration. All work in this thesis can be generated using the single program ROBSIM.FOR.
title: Can factors in the educational environment influence cognitive appraisals of control and value in chiropractic medical students?
Creators: name: Wiles, M
Publisher: name: University of Liverpool Repository
Year: 2019

description: Can factors in the educational environment influence cognitive appraisals of control and value in chiropractic medical students? Michael Wiles Pekrun and co-workers have described a theoretical construct and continuum by which elements of the educational environment are posited to influence cognitive appraisals of control (over one’s academic performance) and value (of one’s education). These appraisals are said to influence what Pekrun called achievement emotions, or emotions that are tied to educational outcomes. This construct suggests that educational outcomes, the worthy goal of any educational program, could be influenced at the onset by the educational environment. This would be of interest to educators in order to manipulate the environment to influence cognitive appraisals, which in turn influence achievement emotions. Chiropractic medical students were surveyed and interviewed to assess their perceptions of the educational environment, control and value. The survey instrument consisted of the fifty questions of the Dundee Ready Educational Environment Measure, and ten questions measuring cognitive appraisal of control and value. These latter ten questions had been previously developed and used in several studies investigating appraisals of control and value. Forty-three students (67.2%) completed the survey instrument and six students were interviewed. The qualitative and quantitative data showed that cognitive appraisal of control was strongly correlated with a wide range of elements of the educational environment, in agreement with Pekrun’s construct. However, the findings also showed that cognitive appraisal of value had little to no correlation with the educational environment and is possibly an intrinsic and independent characteristic of these students. These findings are of specific importance to chiropractic educators by supporting the need for a positive educational environment, and of a more general importance to health science educators by demonstrating the importance of personal and social elements in the learning process. These findings also suggest the need for further research into the nature of the perception of value in chiropractic medical students, and whether the strong correlation of the educational environment and perception of control is due to a cause-effect relationship.

description: Ad platforms such as Facebook, Google and LinkedIn promise value for advertisers through their targeted advertising. However, multiple studies have shown that ad delivery on such platforms can be skewed by gender or race due to hidden algorithmic optimization by the platforms, even when not requested by the advertisers. Building on prior work measuring skew in ad delivery, we develop a new methodology for black-box auditing of algorithms for discrimination in the delivery of job advertisements. Our first contribution is to identify the distinction between skew in ad delivery due to protected categories such as gender or race, from skew due to differences in qualification among people in the targeted audience. This distinction is important in U.S. law, where ads may be targeted based on qualifications, but not on protected categories. Second, we develop an auditing methodology that distinguishes between skew explainable by differences in qualifications from other factors, such as the ad platform's optimization for engagement or training its algorithms on biased data. Our method controls for job qualification by comparing ad delivery of two concurrent ads for similar jobs, but for a pair of companies with different de facto gender distributions of employees. We describe the careful statistical tests that establish evidence of non-qualification skew in the results. Third, we apply our proposed methodology to two prominent targeted advertising platforms for job ads: Facebook and LinkedIn. We confirm skew by gender in ad delivery on Facebook, and show that it cannot be justified by differences in qualifications. We fail to find skew in ad delivery on LinkedIn. Finally, we suggest improvements to ad platform practices that could make external auditing of their algorithms in the public interest more feasible and accurate.

description: The periodic changes in the physical and chemical properties of the chemical elements are caused by the periodic change of the ionization energies, which are constant for each element that manifested in the Periodic Table. However, as has been recently shown the modification of the electromagnetic field in the photonic crystals gives rise to the modification of the electron electromagnetic mass. We show that the effect can significantly change the ionization energy of atoms placed in voids of photonic crystals consisting of metamaterials with a highly tunable refractive index and voids. The controllability of these materials gives rise to the controllability of the ionization energies over a wide range.

description: Aims: In the context of space interferometry missions devoted to the search of exo-Earths, this paper investigates the capabilities of new single mode conductive waveguides at providing modal filtering in an infrared and monochromatic nulling experiment; Methods: A Michelson laser interferometer with a co-axial beam combination scheme at 10.6 microns is used. After introducing a Pi phase shift using a translating mirror, dynamic and static measurements of the nulling ratio are performed in the two cases where modal filtering is implemented and suppressed. No additional active control of the wavefront errors is involved. Results: We achieve on average a statistical nulling ratio of 2.5e-4 with a 1-sigma upper limit of 6e-4, while a best null of 5.6e-5 is obtained in static mode. At the moment, the impact of external vibrations limits our ability to maintain the null to 10 to 20 seconds.; Conclusions: A positive effect of SM conductive waveguide on modal filtering has been observed in this study. Further improvement of the null should be possible with proper mechanical isolation of the setup.

description: This document is a short report that accompanies the software deliverable D3.4 “Language Resource and Service Linking''. The idea is to serve as a guideline of the different linking algorithms and systems developed in Prêt-à-LLOD as part of the “Prêt-à-LLOD-Link'' component: what are their basic functionalities, how the different sub-components are interrelated, and how they relate with other Prêt-à-LLOD components, particularly “Prêt-à-LLOD-Transform'' and “Prêt-à-LLOD-Workflows”. The document serves also as a pointer to the repositories where the code, along with a more complete technical documentation, is available.
 While the initial Prêt-à-LLOD linking software is released with this deliverable, it will be continuously improved and updated until later stages of the project. In fact, further testing and development is expected as part of the integration of the linking component with the “Language Resource Transformation Software” (deliverable D3.3, due in month M33), with the pilots (deliverables D4.3, D4.5, D4.7, D4.9, due in month M36), and as part of the progress of the overall Prêt-à-LLOD research challenges (deliverable D3.6, due in month M39). Such deliverable D3.6 will provide the final snapshot of the software component initially delivered in D3.4, and will update its status at the end of the project.

description: Semiclassical reasoning suggests that the process by which an object collapses into a black hole and then evaporates by emitting Hawking radiation may destroy information, a problem often referred to as the black hole information paradox. Further, there seems to be no unique prediction of where the information about the collapsing body is localized. We propose that the latter aspect of the paradox may be a manifestation of an inconsistent self-reference in the semiclassical theory of black hole evolution. This suggests the inadequacy of the semiclassical approach or, at worst, that standard quantum mechanics and general relavity are fundamentally incompatible. One option for the resolution for the paradox in the localization is to identify the Gödel-like incompleteness that corresponds to an imposition of consistency, and introduce possibly new physics that supplies this incompleteness. Another option is to modify the theory in such a way as to prohibit self-reference. We discuss various possible scenarios to implement these options, including eternally collapsing objects, black hole remnants, black hole final states, and simple variants of semiclassical quantum gravity.

The effects of slashburning on the growth and nutrition of young Douglas-fir plantations in some dry, salal-dominated ecosystems
Creators: name: Vihnanek, Robert E.
Publisher: name: University of British Columbia
Year: 2010

description: Twenty Douglas-fir plantations, ranging from 5 to 15 years old, were examined on the east side of Vancouver Island. In all areas studied, salal was the dominant ground cover, and was suspected of being a major competitor with trees for water and nutrients. In each plantation, part of the area has been burned and part was unburned. Stocking of planted Douglas-firs was found to be greater on the burned than on the unburned areas of 16 sites and height growth of planted Douglas-firs was greater on the burned than on the unburned areas of 18 sites. Some degree of nitrogen deficiency was inferred for 17 sites, but was not attributed to burning. Height and percent cover of salal was greater on unburned areas. Differences in height growth and percent cover of salal between burned and unburned areas were seen to be greatest where inferred burn severity was high. Browsing of Douglas-fir was more prevalent on burned areas but did not result in height growth being less than on adjacent unburned areas.

description: We investigate the electron transport through a graphene p-n junction under a perpendicular magnetic field. By using Landauar-Buttiker formalism combining with the non-equilibrium Green function method, the conductance is studied for the clean and disordered samples. For the clean p-n junction, the conductance is quite small. In the presence of disorders, it is strongly enhanced and exhibits plateau structure at suitable range of disorders. Our numerical results show that the lowest plateau can survive for a very broad range of disorder strength, but the existence of high plateaus depends on system parameters and sometimes can not be formed at all. When the disorder is slightly outside of this disorder range, some conductance plateaus can still emerge with its value lower than the ideal value. These results are in excellent agreement with the recent experiment.

description: The dynamics of interacting dark matter-dark energy models is characterized through an interaction rate function quantifying the energy flow between these dark sectors. In most of the interaction functions, the expansion rate Hubble function is considered and sometimes it is argued that, as the interaction function is a local property, the inclusion of the Hubble function may influence the overall dynamics. This is the starting point of the present article where we consider a very simple interacting cosmic scenario between vacuum energy and the cold dark matter characterized by various interaction functions originated from a general interaction function: $Q= Γρ_{c}^{α}ρ_{x}^{1-α-β}(ρ_{c}+ρ_{x})^β$, where $ρ_c$, $ρ_x$ are respectively the cold dark matter density and vacuum energy density; $α$, $β$ are real numbers and $Γ$ is the coupling parameter with dimension equal to the dimension of the Hubble rate. We investigate four distinct interacting cosmic scenarios and constrain them both theoretically and observationally. Our analyses clearly reveal that the interaction models should be carefully handled.

description: Intrinsic properties of the space itself and quantum fluctuations of its geometry are sufficient to provide a mechanism for the acceleration of cosmological expansion (dark energy effect). Applying Bogoliubov-Born-Green-Kirkwood-Yvon hierarchy approach to self-consistent equations of one-loop quantum gravity, we found exact solutions that yield acceleration. The permanent creation and annihilation of virtual gravitons is not in exact balance because of the expansion of the Universe. The excess energy comes from the spontaneous process of graviton creation and is trapped by the background. It provides the macroscopic quantum effect of cosmic acceleration.

description: Starting with unitary quantum dynamics, we investigate how to add quantum measurements. Quantum measurements have four essential components: the furcation, the witness production, an alignment projection, and the actual choice decision. The first two components still lie in the domain of unitary quantum dynamics. The decoherence concept explains the third contribution. It can be based on the requirement that witnesses reaching the end of time on the wave function side and the conjugate one have to be identical. In this way, it also stays within the quantum dynamics domain. The surjection hypothesis explains the actual choice decision. It is based on a two boundary interpretation applied to the complete quantum universe. It offers a simple way to reduce these seemingly random projections to purely deterministic unitary quantum dynamics, eliminating the measurement problem.

description: Život u naselju iz ranog bronzanog doba (2800–3100 p.n.e.) na nalazištu Arslantepe je okončan požarom koji je za sobom ostavio ogroman broj ugljenisanih botaničkih ostataka in situ. Кako je materijal pohranjen usled jednog, iznenadnog događaja koji je pogodio celo selo, omogućeno je podrobno razumevanje konteksta i interpretacija različitih praksi, naročito poljoprivrednih. Otkriveno je nekoliko prostorija u kojima su skladišteni usevi i namirnice, za šta su upotrebljavani silosi, velike keramičke posude poput pitosa, a najverovatnije i korpe ili kese od organskog materijala, koji se nije očuvao. Takođe, veliki broj karpoloških ostataka potiče sa spratova kuća, koji su ovde mogli dospeti usled upotrebe spratnog prostora za skladištenje ili pak za sušenje useva nakon žetve. Među karpološkim ostacima usevnih biljaka dominiraju ugljenisana zrna žitarica, pre svega ječma (Hordeum vulgare), jednozrne (Triticum monococcum) i dvozrne pšenice (T. dicoccon), a u manjoj količini prisutna je i obična/tvrda pšenica (T. aestivum/durum). U velikoj meri zastupljene su i mahunarke, najviše grašak (Pisum sativum) i leblebija (Cicer arietinum), ali su dokumentovane i manje ukusne semenke iz rodova grahorica (Vicia/Lathyrus). Ječam je skladišten zasebno, za razliku od ostalih žitarica, što znači da je tako i uzgajan i obrađivan. Mahunarke su u većini uzoraka nalažene izmešane. Svi usevi su veoma dobro očišćeni pre skladištenja što se može zaključiti na osnovu potpunog odsustva korovskih biljaka i pleve. Podaci o praksama skladištenja značajni su i za sagledavanje društveno-ekonomskih odnosa. U saglasnosti sa prethodnim zaključcima baziranim na arheološkim dokazima, uočljivo je da stanovnici ovog ratarskog naselja privredu sprovode na nivou domaćinstva, što je u suprotnosti sa centralističkim sistemom i pojavom vladajućih elita u prethodnom, kasno-halkolitskom, periodu.

We show that at particular times during the evolution spatial and spin dynamics disentangle and the spin squeezing can be predicted by a simple two-mode model. We calculate the maximum spin squeezing achievable in experimentally relevant situations with Sodium or Rubidium bimodal condensates, including the effect of the dynamics and of one, two and three-body losses.

description: We study the topological phase transitions induced by Coulomb engineering in three triangular-lattice Hubbard models $AB_2$, $AC_3$ and $B_2C_3$, each of which consists of two types of magnetic atoms with opposite magnetic moments. The energy bands are calculated using the Schwinger boson method. We find that a topological phase transition can be triggered by the second-order (three-site) virtual processes between the two types of magnetic atoms, the strengths of which are controlled by the on-site Coulomb interaction $U$. This new class of topological phase transitions have been rarely studied and may be realized in a variety of real magnetic materials.

description: Emotion recognition in conversations is an important step in various virtual chat bots which require opinion-based feedback, like in social media threads, online support and many more applications. Current Emotion recognition in conversations models face issues like (a) loss of contextual information in between two dialogues of a conversation, (b) failure to give appropriate importance to significant tokens in each utterance and (c) inability to pass on the emotional information from previous utterances.The proposed model of Advanced Contextual Feature Extraction (AdCOFE) addresses these issues by performing unique feature extraction using knowledge graphs, sentiment lexicons and phrases of natural language at all levels (word and position embedding) of the utterances. Experiments on the Emotion recognition in conversations dataset show that AdCOFE is beneficial in capturing emotions in conversations.

Acid-base balance in arterial plasma of white Pekin duck (Anas platyrhynchos) during forced submergence and recovery
Creators: name: Shimizu, Manabu
Publisher: name: University of British Columbia
Year: 2010

description: Acid-base balance in plasma was studied in forcibly submerged Pekin ducks (Anas platyrhynchos). All important variables determining acid-base balance (arterial CO₂ tension (PαCO₂) strong ion difference ([SID]) and total protein content which approximates total weak acid concentration in plasma) were measured. During forced submergence PαCO₂ increased and pHa steadily decreased with time. There was also an increase in [lactate⁻], which was accompanied by an increase of equal magnitude in [Na⁺]. There were no significant changes in the concentrations of other strong ions (K⁺, Ca²⁺, Mg²⁺ and Cl⁻). Strong ion difference did not change during the first two minutes of submergence, but there was about a 4 mequiv/L increase by the end of the four-minute dive. Theoretically an increase in [SID] should cause plasma to be alkaline, but since plasma became progressively acidic, this condition can only be due to the increase in PαCO₂. During recovery from dives, the plasma remained as acidic one minute after emersion as at the end of the dives. On the other hand, arterial pH slowly increased towards the pre-dive level during recovery. Arterial CO₂ tension decreased much more rapidly and was already at or below the pre-dive level one minute after emersion. Therefore, PαCO₂ could no longer affect plasma pH. There was, however, a great increase in [lactate-] in the first minute of recovery. Although [Na⁺] and [K⁺] were elevated, from pre-dive values after the four minute dive, the increase in [lactate⁻] resulted in a marked reduction in [SID]. Since there was no change in the total plasma protein content, the acidic condition observed in recovery could only be due to decreased [SID]. Breathing 0₂ before diving prevented circulatory adjustments and pH returned to pre-dive levels one minute after emersion, confirming that the acidic condition observed in recovery is a consequence of the lactate produced in the hypoperfused tissues during submergence.

description: A new micro/mesoporous hybrid clay nanocomposite prepared from kaolinite clay, Carica papaya seeds, and ZnCl2 via calcination in an inert atmosphere is presented. Regardless of the synthesis temperature, the specific surface area of the nanocomposite material is between ≈150 and 300 m2/g. The material contains both micro- and mesopores in roughly equal amounts. X-ray diffraction, infrared spectroscopy, and solid-state nuclear magnetic resonance spectroscopy suggest the formation of several new bonds in the materials upon reaction of the precursors, thus confirming the formation of a new hybrid material. Thermogravimetric analysis/differential thermal analysis and elemental analysis confirm the presence of carbonaceous matter. The new composite is stable up to 900 °C and is an efficient adsorbent for the removal of a water micropollutant, 4-nitrophenol, and a pathogen, E. coli, from an aqueous medium, suggesting applications in water remediation are feasible.

description: We consider the dynamics of fluctuations in the quantum asymmetric simple exclusion process (Q-ASEP) with periodic boundary conditions. The Q-ASEP describes a chain of spinless fermions with random hoppings that are induced by a Markovian environment. We show that fluctuations of the fermionic degrees of freedom obey evolution equations of Lindblad type, and derive the corresponding Lindbladians. We identify the underlying algebraic structure by mapping them to non-Hermitian spin chains and demonstrate that the operator space fragments into exponentially many (in system size) sectors that are invariant under time evolution. At the level of quadratic fluctuations we consider the Lindbladian on the sectors that determine the late time dynamics for the particular case of the quantum symmetric simple exclusion process (Q-SSEP). We show that the corresponding blocks in some cases correspond to known Yang-Baxter integrable models and investigate the level-spacing statistics in others. We carry out a detailed analysis of the steady states and slow modes that govern the late time behaviour and show that the dynamics of fluctuations of observables is described in terms of closed sets of coupled linear differential-difference equations. The behaviour of the solutions to these equations is essentially diffusive but with relevant deviations, that at sufficiently late times and large distances can be described in terms of a continuum scaling limit which we construct. We numerically check the validity of this scaling limit over a significant range of time and space scales. These results are then applied to the study of operator spreading at large scales, focusing on out-of-time ordered correlators and operator entanglement.

description: A thermodynamic-like formalism is developed for superstatistical systems based on conditional entropies. This theory takes into account large-scale variations of intensive variables of systems in nonequilibrium stationary states. Ordinary thermodynamics is recovered as a special case of the present theory, and corrections to it can be systematically evaluated. A generalization of Einstein's relation for fluctuations is presented using a maximum entropy condition.

description: Asteroseismic modelling of the internal structure of main-sequence stars born with a convective core has so far been based on homogeneous analyses of space photometric Kepler light curves of 4 years duration, to which most often incomplete inhomogeneously deduced spectroscopic information was added to break degeneracies. We composed a sample of 111 dwarf gravity-mode pulsators observed by the Kepler space telescope whose light curves allowed for determination of their near-core rotation rates. For this sample we assembled HERMES high-resolution optical spectroscopy at the 1.2-m Mercator telescope. Our spectroscopic information offers additional observational input to also model the envelope layers of these non-radially pulsating dwarfs. We determined stellar parameters and surface abundances in a homogeneous way from atmospheric analysis with spectrum normalisation based on a new machine learning tool. Our results suggest a systematic overestimation of [M/H] in the literature for the studied F-type dwarfs, presumably due to normalisation limitations caused by the dense line spectrum of these rotating stars. CNO-surface abundances were found to be uncorrelated with the rotation properties of the F-type stars. For the B-type stars, we find a hint of deep mixing from C and O abundance ratios; N abundances have too large uncertainties to reveal a correlation with the rotation of the stars. Our spectroscopic stellar parameters and abundance determinations allow for future joint spectroscopic, astrometric (Gaia), and asteroseismic modelling of this legacy sample of gravity-mode pulsators, with the aim to improve our understanding of transport processes in the core-hydrogen burning phase of stellar evolution.

Correlated entanglement distillation and the structure of the set of undistillable states

description: We consider entanglement distillation under the assumption that the input states are allowed to be correlated among each other. We hence replace the usually considered independent and identically-distributed hypothesis by the weaker assumption of merely having identical reductions. We find that whether a state is then distillable or not is only a property of these reductions, and not of the correlations that are present in the input state. This is shown by establishing an appealing relation between the set of copy-correlated undistillable states and the standard set of undistillable states: The former turns out to be the convex hull of the latter. As an example of the usefulness of our approach to the study of entanglement distillation, we prove a new activation result, which generalizes earlier findings: it is shown that for every entangled state and every positive integer k, there exists a copy-correlated k-undistillable state such that their tensor product is single-copy distillable. Finally, the relation of our results to the conjecture about the existence of bound entangled states with a non-positive partial transpose is discussed.
