Weather conditions in one region can often be linked to conditions in another region thousands of miles away. These long-distance relationships are known as teleconnections and play a large role in our ocean-atmosphere system, including global weather patterns. Some recurring deviations, or anomalies, in regional weather patterns are commonly referred to as oscillations. This project focused on common spatial oscillations that affect North American weather patterns: the North Atlantic Oscillation (NAO), the Pacific Decadal Oscillation (PDO) and the El Niño/Southern Oscillation (ENSO). These phenomena are monitored using climate indices, which are calculated monthly from relevant physical variables representing the state of the oscillation over a specific region. Contemporaneous and lagged correlation analysis was used to investigate relationships among four indices: the NAO index, the PDO index, the Southern Oscillation Index (SOI) and the Niño3.4 SST index. Results show the autocorrelation function of the PDO is highly significant (at the 5% level) for at least one year and still significant out to at least seven years, which was the length of time allowed by the 60-year (1951-2011) dataset. The Niño3.4 autocorrelation is negative (significant at the 5% level) around 24 months, which indicates a transition in the ENSO from a positive to a negative phase, and significantly positive again around 50 months. The maximum correlation between the PDO Index and the Niño3.4 SST Index is 0.52 (highly significant), with the PDO leading the Niño3.4 by two months. Understanding correlations and whether there exists relationships between teleconnections may improve seasonal weather forecasting.

description: Mathematical morphology is a theory concerned with non-linear operators for image processing and analysis. The underlying framework for mathematical morphology is a partially ordered set with well-defined supremum and infimum operations. Because vectors can be ordered in many ways, finding appropriate ordering schemes is a major challenge in mathematical morphology for vector-valued images, such as color and hyperspectral images. In this context, the irregularity issue plays a key role in designing effective morphological operators. Briefly, the irregularity follows from a disparity between the ordering scheme and a metric in the value set. Determining an ordering scheme using a metric provide reasonable approaches to vector-valued mathematical morphology. Because total orderings correspond to paths on the value space, one attempt to reduce the irregularity of morphological operators would be defining a total order based on the shortest length path. However, this paper shows that the total ordering associated with the shortest length path does not necessarily imply minimizing the irregularity.

description: The shoulder is a complex joint with a wide range of motion, including flexion, extension, abduction, adduction, and internal and external rotation. In volleyball, repetitive overhand movements can cause shoulder overuse injuries. The primary offensive move, the attack, involves the approach, arm cocking, arm acceleration, and follow-through phases. Motion capture analysis and techniques like calculating Euler angles and rotation about a mean helical axis can evaluate shoulder movements. This study aimed to calculate shoulder movements during each phase of the volleyball attack using the Euler angle YXY sequence and the helical axis method. Different attack types, such as cross-court and line attacks, as well as cross-body and same-side follow-through strategies, were compared. Sixteen highly competitive or professional volleyball players participated, completing a series of attacks with varying directions and follow-through strategies in random order. Data were processed in Visual3d, and kinematics were calculated using custom MATLAB programs. Results indicated that the helical axis method revealed patterns of shoulder movements during the approach phase, suggesting that arm cocking might begin before takeoff. Both methods showed minimal variation during the arm cocking phase. Significant differences in the angle of elevation were observed during the arm acceleration phase between cross-court cross-body and line same-side attacks. The follow-through phase showed differences, with cross-body attacks involving more dynamic shoulder movements and same-side attacks exhibiting smoother motions. These findings highlight distinct shoulder mechanics in different volleyball strategies and underscore the helical axis method's effectiveness in optimizing performance and preventing injuries.

description: We argue that the X-ray and UV flux illuminating the parsec-scale accretion disk around luminous active galactic nuclei (AGN) is super-Eddington with respect to the local far-infrared dust opacity. The far infrared opacity may be larger than in the interstellar medium of the Milky Way due to a combination of supersolar metallicity and the growth of dust grains in the dense accretion disk. Because of the irradiating flux, the outer accretion disk puffs up with a vertical thickness $h\sim R$. This provides a mechanism for generating a geometrically thick obscuring region from an intrinsically thin disk. We find obscuring columns $\sim 10^{22} - 10^{23} {\rm cm}^{-2}$, in reasonable agreement with observations.

description: We present evidence from computer simulations for glassy dynamics in suspensions of monodisperse hard ellipsoids. In equilibrium, almost spherical ellipsoids show a first order transition from an isotropic phase to a rotator phase. When overcompressing the isotropic phase into the rotator regime, we observe super-Arrhenius slowing down of diffusion and relaxation, accompanied by two-step relaxation in positional and orientational correlators. The effects are strong enough for asymptotic laws of mode-coupling theory to apply. Glassy dynamics are unusual in monodisperse systems. Typically, polydispersity in size or a mixture of particle species is prerequisite to prevent crystallization. Here, we show that a slight particle anisometry acts as a sufficient source of disorder. This sheds new light on the question of which ingredients are required for glass formation.

Increasing the efficiency of GEOS-Chem Adjoint model runs using a Python ensemble manager

Methane is a powerful greenhouse gas with uncertainty regarding the strengths and trends of various individual sources. These uncertainties make it difficult for researchers to determine the exact reasons behind methaneâs variable annual growth rate and the stabilization of the atmospheric concentration over the past three decades. It is possible to estimate individual methane source emission values using satellite measurements and inverse modeling techniques, although data quality limits how well individual sources are resolved. GEOS-Chem Adjoint is the combination of an atmospheric chemical transport model (GEOS-Chem) with an adjoint model, and it can be used to test the emissions source resolving power for actual and theoretical satellite retrievals of methane. In order to test the resolving power, the mathematical calculations require a large number of individual simulations to be run, but currently in the standard version of GEOS-Chem Adjoint each simulation needs to be manually set up and initiated. To overcome the need for manual setup and executions of model runs, a manager script was created using the Python programming language. The ensemble manager script, PyEnsemble, automates the process of creating multiple unique simulations, and can run variable numbers of simulations on many different types of clustered computer systems. PyEnsemble marks the first step in a larger project of testing the current accuracy of methane surface emission estimates, and helping to develop ways to help further constrain them.
Paraphilias and Violence in the couple. An integrative approach
Creators: name: Iacone, Stefano
Publisher: name: University of Messina
Year: 2019

description: The systemic therapy has given great attention to the violent dynamics of couples, but has rarely connected the different forms of violence with the Paraphilic Disorder. The phenomenology of the Paraphilic Disorder tells us the violence is a certain and fixed data instead. The common perception about Paraphilic Disorder is based on the image of a solitary individual coercively chained to rigid and stereotypical sexual fantasies. Clinical practice, on the other hand, tells us that, in most cases of Paraphilic Disorder, the patient forms a fixed or long-lasting couple and therefore shares and elaborates the perverse ritual with a partner. So it’s necessary view four levels to understand the "evil", the hatred, that leads to dehumanize the partner: genetic baggage, motivational systems organization, relational pattern and emerging qualities of bonds. Generally the systemic approach has given great attention to the two later points. In particular, in this paper the author supports the importance of understanding and healing the “third world” that every couple co-create: the couple's absolute (Caillè, 2007). In this paper the couple's absolute are called the “We”, meaning a collective mental dimension that contains mythological, cognitive and somatic aspects that generate a unique identity for each couple. If the therapist understand the “We”, can grasp the real meaning of the violent acts in the couple and this is a central point of a real therapeutic change.

The North American monsoon (NAM), characterized by distinct seasonal precipitation over western Mexico and the Southwestern United States, is a summertime phenomenon that depends on complex interactions between the Pacific Ocean, Gulf of Mexico, and the North American land mass. Thus, the NAM is strongly influenced by the El Niño Southern Oscillation, a dominant mode of interannual Pacific sea surface temperature (SST) and atmospheric variability, as well as the North Pacific Oscillation, a low-frequency (decadal) Pacific variation. This study assesses present day and projected changes in the NAM precipitation on a yearly and seasonal basis. Observations from the NCEP-NCAR Reanalysis project are compared to the Community Climate System Model version 4 (CCSM) from 1980 to 2000. Spatial patterns agree well, but still show an overestimation in precipitation within the NAM region. Fifteen CCSM ensemble runs, for various IPCC AR4 emission scenarios (A2, B1, and constant CO2), are assessed within each specific scenario and averaged, for comparisons between 1980-2000 and 2080-2100. In the NAM region we find yearly and seasonal decreases in precipitation and increases in temperature for all IPCC emission scenarios. Although this may be, modest RCP’s (4.5, 2.6) will have difficulty in detecting a signal above the noise within its scenario. Our analysis further finds statistical significance to the differences in mean precipitation and temperature over the NAM region, due in part to different levels of CO2 in the atmosphere.

description: Inspired by the recent evidences of nano-Hertz stochastic gravitational waves observed by the pulsar timing array collaborations, we explore their implied supercooled electroweak phase transition in the singlet extension of the Standard Model. Our findings reveal that by adjusting the model parameter at per milli level, the corresponding percolation temperature can be continuously lowered to 1 GeV. With such a low percolation temperature, the singlet dark matter may freeze out before the electroweak phase transition, and, consequently, the entropy generated during the transition can significantly affect the dark matter relic density. It alleviates the tension between the requirement of a strong electroweak phase transition and the constraints imposed by dark matter direct detection, and can be tested in future experiments.

description: Presentation delivered on October 28, 2022 at Adam Mickiewicz University, Poznań, Poland. Abstract Open science, broadly defined as a set of scholarly practices aiming to make scientific knowledge and the means to achieve it universally accessible, has been proposed as a solution to many of the problems that are present in current academic practices. The concept was born in STEM disciplines, and consequently not all open-science practices are (directly) applicable to social sciences and humanities-oriented disciplines, such as linguistics, translation & interpreting studies, and literary studies. In this talk, I will present the principles of open science, discuss the main open-science practices (open access, open methods and tools, open data, open peer review, and open research evaluation), and examine how these practices have been applied or to what extent they are applicable to translation & interpreting studies as a case in point. Additionally, I will suggest resources for bringing academic practices in line with the principles of open science. At the end of the talk, floor will be open for discussion on the opportunities and challenges of implementing these practices in the disciplines represented by the attendees of the talk.

Psychodynamic insights from narratives of people with amyotrophic lateral sclerosis: A qualitative phenomenological study
Creators: name: Caputo, Andrea
Publisher: name: University of Messina
Year: 2019

description: This study explored the illness experience of people with amyotrophic lateral sclerosis (ALS) to widen narrative research on patients’ perspectives, adopting object relations theory as interpretative framework. A qualitative phenomenological analysis was conducted on the illness stories of 12 adult Italian patients with ALS, collected through an Internet-based database for the sharing of illness experiences of people with rare and chronic degenerative diseases. Three thematic areas were identified: “the experience of ALS from symptom onset to diagnosis”, “impact of illness”, and “coping with illness”. Overall, the central conflict experienced by people with ALS refers to the progressive loss of control on bodily experience, that is handled by means of denial and splitting defences to contrast such a process of somatic depersonalization. As well, the investment on interpersonal domain responds to a repairing strategy ensuring psychic vitality and sensorial integration to rebuild the relation between the self and the external world.

description: We study the quantum critical effect enhanced spin-nematic squeezing and quantum Fisher information (QFI) in the spin-1 dipolar atomic Bose-Einstein condensate. We show that the quantum phase transitions can improve the squeezing and QFI in the nearby regime of critical point, and the Heisenberg-limited high-precision metrology can be obtained. The different properties of the ground squeezing and entanglement under even and odd number of atoms are further analyzed, by calculating the exact analytical expressions.We also demonstrate the squeezing and entanglement generated by the spin-mixing dynamics around the phase transition point. It is shown that the steady squeezing and entanglement can be obtained, and the Bogoliubov approximation can well describe the dynamics of spin-nematic squeezed vacuum state.

description: To observe the seminal plasma proteomic composition in men with spinal cord injury orally treated with probenecid, in order to observe pathways associated with increased sperm motility. Prospective study. Miami Project to Cure Paralysis – University of Miami/Miller School of Medicine. Nine men with spinal cord injury, who agreed to participate in the study. Oral treatment with probenecid – 500 mg per day for one week, then 500 mg twice daily [1000 mg total] per day for three weeks. Semen analysis as per WHO 2010 guidelines, and seminal plasma proteomics analysis by LC-MS/MS. In total, 783 proteins were identified, of which, 17 were decreased, while 6 were increased after treatment. The results suggest a new pathway that could be treated by the decrease of biglycan after probenecid treatment. Oral treatment with probenecid is able to alter the seminal plasma proteome, in pathways that explain decreased innate immune response.
Inquiry into J.S. Bach’s method of reworking in his composition of the concerto for keyboard, flute and violin, BWV 1044, and its chronology
Creators: name: Douglas, David James
Publisher: name: University of British Columbia
Year: 2009

description: Bach's Concerto for Keyboard, Flute, and Violin with Orchestra in A minor, BWV 1044, is a very interesting and unprecedented case of Bach reworking pre-existing keyboard works into three concerto movements. There are several examples of Bach carrying out the reverse process with his keyboard arrangements of Vivaldi, and other composers' concertos, but the reworking of the Prelude and Fugue in A minor, BWV 894, into the outer movements of BWV 1044, and the second movement of the Organ Sonata in F major, BWV 527, into the middle movement, appears to be unique among Bach's compositional activity. This study will explore in some detail how Bach transforms these solo keyboard pieces into a three movement concerto for three concertino instruments and ripieno. As is the case with most of Bach's instrumental works, the question of where BWV 1044 fits within the chronology of Bach's works is unclear. This paper will attempt a reliable date of composition for this concerto by combining a variety of methods including source study and comparative formal analysis.

description: We perform large eddy simulations of flow past a circular cylinder for the Reynolds number ($Re$) range, $2\times 10^3 \leq Re \leq 4\times10^5$, spanning subcritical, critical and supercritical regimes. We investigate the spanwise coherence of the flow in the critical and supercritical regimes using complex networks. In these regimes, the separated flow reattaches to the surface in a turbulent state due to the turbulence generated by the shear layer instability. In the early critical regime, the turbulent reattachment does not occur simultaneously at all span locations. It occurs incoherently along the span in clusters. We treat strong surface pressure fluctuations due to the shear layer instability as extreme events and construct time-varying spatial proximity networks where links are based on synchronization between events. This analysis unravels the underlying complex spatio-temporal dynamics by enabling the estimation of characteristics of clusters of turbulent reattachment via the concept of connected components. In the critical regime, the number and size of the clusters increase with increase in $Re$. At higher $Re$ in the supercritical regime, they coalesce to form bigger clusters, resulting in increase in spanwise coherence of turbulent reattachment. We find that the size and number of clusters govern the variation of the time-averaged coefficient of drag ($\overline{C}_D$) in the critical and supercritical regimes. $\overline{C}_D$ exhibits power-law distribution with the most probable cluster size ($\overline{C}_D \propto E(S_C)^{-\frac{2}{5}}$) and the largest cluster size ($\overline{C}_D \propto {\overline{S}_{CL}}^{-\frac{2}{5}}$).

description: In this work, we present a protocol for comparing the performance of arbitrary quantum processes executed on spatially or temporally disparate quantum platforms using Local Operations and Classical Communication (LOCC). The protocol involves sampling local unitary operators, which are then communicated to each platform via classical communication to construct quantum state preparation and measurement circuits. Subsequently, the local unitary operators are implemented on each platform, resulting in the generation of probability distributions of measurement outcomes. The max process fidelity is estimated from the probability distributions, which ultimately quantifies the relative performance of the quantum processes. Furthermore, we demonstrate that this protocol can be adapted for quantum process tomography. We apply the protocol to compare the performance of five quantum devices from IBM and the "Qianshi" quantum computer from Baidu via the cloud. Remarkably, the experimental results reveal that the protocol can accurately compare the performance of the quantum processes implemented on different quantum computers, requiring significantly fewer measurements than those needed for full quantum process tomography. We view our work as a catalyst for collaborative efforts in cross-platform comparison of quantum computers.

description: Research has shown a link between specific learning disorders (SLD) and both internalizing (e.g., anxiety and depression) and externalizing problems (e.g., anger and aggressive behavior). However, the predictive factors of these behaviors have not been examined in significant depth. The main purpose of the present study is, therefore, to investigate the possible presence of learned helplessness as the main predictor of the development of internalizing/externalizing problems in students. The present study also aims to verify whether there are differences between pre-adolescent students with and without SLD in terms of learned helplessness in school and the development of internalizing/externalizing problems. The sample consisted of 84 students, with an average age of 12.9 years (SD= 1.42). A total of 52 males (62 %) and 32 females (38 %) were divided into two groups, based on the presence of SLD (44 students with SLD and 40 without). The results showed that students with SLD demonstrated higher levels of internalizing problems. Further, although learned helplessness in a student was not a predictor of externalizing problems in the group without SLD, it was predictive of internalizing and externalizing problems in the group with it. The study’s results, directions for future research, and implications for the psychological wellbeing of students are also discussed.

description: To examine associations of patient characteristics and treatment quantity delivered during inpatient spinal cord injury (SCI) rehabilitation with outcomes at 5 years post-injury and compare them to the associations found at 1 year post-injury. Observational study using Practice-Based Evidence research methodology in which clinicians documented treatment details. Regression modeling was used to predict outcomes. Five inpatient SCI rehabilitation centers in the US. Participants were 792 SCIRehab participants who were >12 years of age, gave informed consent, and completed both a 1-year and 5-year post-injury interview. Outcome data were derived from Spinal Cord Injury Model Systems (SCIMS) follow-up interviews at 5 years post-injury and, similar to the 1-year SCIMS outcomes, included measures of physical independence, societal participation, life satisfaction, and depressive symptoms, as well as place of residence, school/work attendance, rehospitalization, and presence of pressure ulcers. Consistent with 1-year findings, patient characteristics continue to be strong predictors of outcomes 5-years post-injury, although several variables add to the prediction of some of the outcomes. More time in physical therapy and therapeutic recreation were positive predictors of 1-year outcomes, which held less true at 5 years. Greater time spent with psychology and social work/case management predicted greater depressive symptomatology 5-years post-injury. Greater clinician experience was a predictor at both 1- and 5 -years, although the related positive outcomes varied across years. Various outcomes 5-years post-injury were primarily explained by pre-and post-injury characteristics, with little additional variance offered by the quantity of treatment received during inpatient rehabilitation.

description: Clustering analysis is one of the most widely used statistical tools in many emerging areas such as microarray data analysis. For microarray and other high-dimensional data, the presence of many noise variables may mask underlying clustering structures. Hence removing noise variables via variable selection is necessary. For simultaneous variable selection and parameter estimation, existing penalized likelihood approaches in model-based clustering analysis all assume a common diagonal covariance matrix across clusters, which however may not hold in practice. To analyze high-dimensional data, particularly those with relatively low sample sizes, this article introduces a novel approach that shrinks the variances together with means, in a more general situation with cluster-specific (diagonal) covariance matrices. Furthermore, selection of grouped variables via inclusion or exclusion of a group of variables altogether is permitted by a specific form of penalty, which facilitates incorporating subject-matter knowledge, such as gene functions in clustering microarray samples for disease subtype discovery. For implementation, EM algorithms are derived for parameter estimation, in which the M-steps clearly demonstrate the effects of shrinkage and thresholding. Numerical examples, including an application to acute leukemia subtype discovery with microarray gene expression data, are provided to demonstrate the utility and advantage of the proposed method.

description: Ultracold atomic gases can undergo phase transitions that mimic relativistic vacuum decay, allowing us to empirically test early-Universe physics in tabletop experiments. We investigate the physics of these analog systems, going beyond previous analyses of the classical equations of motion to study quantum fluctuations in the cold-atom false vacuum. We show that the fluctuation spectrum of this vacuum state agrees with the usual relativistic result in the regime where the classical analogy holds, providing further evidence for the suitability of these systems for studying vacuum decay. Using a suite of semiclassical lattice simulations, we simulate bubble nucleation from this analog vacuum state in a 1D homonuclear potassium-41 mixture, finding qualitative agreement with instanton predictions. We identify realistic parameters for this system that will allow us to study vacuum decay with current experimental capabilities, including a prescription for efficiently scanning over decay rates, and show that this setup will probe the quantum (rather than thermal) decay regime at temperatures $T\lesssim10\,\mathrm{nK}$. Our results help lay the groundwork for using upcoming cold-atom experiments as a new probe of nonperturbative early-Universe physics.

description: We study a twisted vortex bundle where quantized vortices form helices circling around the axis of the bundle in a "force-free" configuration. Such a state is created by injecting vortices into rotating vortex-free superfluid. Using continuum theory we determine the structure and the relaxation of the twisted state. This is confirmed by numerical calculations. We also present experimental evidence of the twisted vortex state in superfluid 3He-B.

description: We study the thermodynamic properties of a freely falling ensemble of gyroscopes after the passage of a weak gravitational wave. Due to the precession memory effect, the thermodynamic quantities will experience a change because of the space-time perturbation. We discuss that this GravoThermo memory effect potentially can be used for the detection of the gravitational waves.

description: Discussed are quantized dynamical systems on orthogonal and affine groups. The special stress is laid on geodetic systems with affinely-invariant kinetic energy operators. The resulting formulas show that such models may be useful in nuclear and hadronic dynamics. They differ from traditional Bohr-Mottelson models where SL$(n,\mathbb{R})$ is used as a so-called non-invariance group. There is an interesting relationship between classical and quantized integrable lattices.
Dynamics of Ultracold Bosons in Artificial Gauge Fields: Angular Momentum, Fragmentation, and the Variance of Entropy

description: We consider the dynamics of two-dimensional interacting ultracold bosons triggered by suddenly switching on an artificial gauge field. The system is initialized in the ground state of a harmonic trapping potential. As a function of the strength of the applied artificial gauge, we analyze the emergent dynamics by monitoring the angular momentum, the fragmentation as well the entropy and variance of the entropy of absorption or single-shot images. We solve the underlying time-dependent many-boson Schrödinger equation using the multiconfigurational time-dependent Hartree method for indistinguishable particles (MCTDH-X). We find that the artificial gauge field implants angular momentum in the system. Fragmentation -- multiple macroscopic eigenvalues of the reduced one-body density matrix -- emerges in sync with the dynamics of angular momentum: the bosons in the many-body state develop non-trivial correlations. Fragmentation and angular momentum are experimentally difficult to assess; here, we demonstrate that they can be probed by statistically analyzing the variance of the image entropy of single-shot images that are the standard projective measurement of the state of ultracold atomic systems.

description: To date few studies deepen the construct of meaning-making at the base on the resilience process for adolescent with multiple sclerosis. Starting from a mixed-method of analysis our aim is to fill the gap in the literature by qualitatively exploring the narrative articulation of meaning-making processes highlighting specificities and differences within groups of narratives with high/medium/low resilience measured through the CYRM-28. We collected 29 narratives. The qualitative analysis shows five meaning-making processes at the base of the resilience process: Dependence vs Autonomy; Reconstruction of the time lines; Integration of limits; Enlarging personal assumptive worldview; Connecting emotions and thought. Compared to narratives with low/high scores, differences were evident in the way such processes were articulated. We propose a framework of central issues in the lives of adolescents with multiple sclerosis and a way to determine how these issues can be useful for developing practices and trajectories to support resilient processes.

description: Ischemic heart disease (IHD), particularly in its chronic stable form, is a subtle pathology due to its silent behavior before developing in unstable angina, myocardial infarction or sudden cardiac death. Machine learning techniques applied to parameters extracted form heart rate variability (HRV) signal seem to be a valuable support in the early diagnosis of some cardiac diseases. However, so far, IHD patients were identified using Artificial Neural Networks (ANNs) applied to a limited number of HRV parameters and only to very few subjects. In this study, we used several linear and non-linear HRV parameters applied to ANNs, in order to confirm these results on a large cohort of 965 sample of subjects and to identify which features could discriminate IHD patients with high accuracy. By using principal component analysis and stepwise regression, we reduced the original 17 parameters to five, used as inputs, for a series of ANNs. The highest accuracy of 82% was achieved using meanRR, LFn, SD1, gender and age parameters and two hidden neurons.

description: Some patients with dysphoria, explosive behaviour, or suicidal ideation, may receive a diagnosis of, and treatment for Bipolar Disorder (BD) and, not infrequently. The coexistence of these two diagnoses has been explained in different ways. Some authors include the BPD in the bipolar spectrum; others are sceptical about the existence of real comorbidity, suggesting a misdiagnosis. This study aimed to assess the personality of this group of poly-diagnosed patients (PolyD) and hypothesised they had a pathological borderline organisation. Via the administration of the Schedler Westen Assessment Procedure (SWAP-200), we compared PolyD patients with those suffering from BPD or BD only. We performed two different MANCOVAs to test PolyD, BPD and BD patients’ differences in PD-factors, Q-traits and age. The sample comprised 45 patients (Mean age=43.3, SD=15.7; Females 57.7%, N=26). BD patients (N=15) did not present any personality disorder, they had a higher functioning and Obsessive Q-traits, and a lower Histrionic PD-factor than both PolyD (N=20) and BPD (N=10) patients. Compared to PolyD patients, BD had inferior PD-Borderline, PD-Antisocial factor and Dependent-Masochistic Q-traits, but there were no other differences with BPD patients. PolyD did not differ from BPD patients in any of the PD-factors and Q-traits. Our results suggest that PolyD patients are different from BD patients and propose to consider the pathological borderline personality as a central core of their disease.
