description: Abstract

Cognitive impairment remains one of the most challenging consequences of stroke, affecting up to one-third of survivors. As traditional rehabilitation methods show limited effectiveness, cortical stimulation techniques such as transcranial magnetic stimulation (TMS) and transcranial direct current stimulation (tDCS) have emerged as promising tools for enhancing cognitive recovery through neuroplasticity. These non-invasive neuromodulation techniques modulate cortical excitability, promoting synaptic plasticity and enhancing recovery in motor and cognitive domains. This review explores the mechanisms behind cortical stimulation, its clinical applications in stroke rehabilitation, and the emerging data from early clinical trials. Evidence suggests that cortical stimulation, when combined with task-specific cognitive training or motor rehabilitation, enhances outcomes by activating shared neural circuits, particularly in regions responsible for memory, attention, and executive function. Early clinical trials have demonstrated that tDCS and TMS, applied during the subacute phase of stroke recovery, significantly improve cognitive outcomes when integrated with physical therapy. Additionally, innovative protocols, such as the combination of virtual reality (VR)-based cognitive rehabilitation with cortical stimulation, have shown promise in accelerating recovery from cognitive deficits. As stroke recovery is time-sensitive, the critical window for effective intervention lies within the first three months post-stroke. This period represents a heightened state of neuroplasticity, during which cortical stimulation can most effectively facilitate cognitive recovery. While challenges remain, such as variability in patient responses and the need for large-scale randomized controlled trials (RCTs), ongoing advancements in neuroimaging biomarkers and personalized treatment algorithms hold potential for optimizing the use of cortical stimulation in stroke rehabilitation. As research progresses, cortical stimulation could revolutionize cognitive rehabilitation by restoring disrupted neural networks and improving functional outcomes for stroke survivors.

description: The nature of the progenitors of type Ia supernovae is still under controversial debate. KPD 1930+2752 is one of the best SN Ia progenitor candidates known today. The object is a double degenerate system consisting of a subluminous B star (sdB) and a massive white dwarf (WD). Maxted et al. (2000) conclude that the system mass exceeds the Chandrasekhar mass. This conclusion, however, rests on the assumption that the sdB mass is 0.5 Mo. However, recent binary population synthesis calculations suggest that the mass of an sdB star may range from 0.3 Mo to more than 0.7 Mo. It is therefore important to measure the mass of the sdB star simultaneously with that of the white dwarf. Since the rotation of the sdB star is tidally locked to the orbit the inclination of the system can be constrained if the sdB radius and the projected rotational velocity can be measured with high precision. An analysis of the ellipsoidal variations in the light curve allows to tighten the constraints derived from spectroscopy. We derive the mass-radius relation for the sdB star from a quantitative spectral analysis of 150 low-resolution spectra. The projected rotational velocity is determined for the first time from 200 high-resolution spectra. In addition a reanalysis of the published light curve is performed. The atmospheric and orbital parameters are measured with unprecedented accuracy. In particular the projected rotational velocity is determined. A neutron star companion can be ruled out and the mass of the sdB is limited between 0.45 Mo and 0.52 Mo. The total mass of the system ranges from 1.36 Mo to 1.48 Mo and hence is likely to exceed the Chandrasekhar mass. So KPD 1930+2752 qualifies as an excellent double degenerate supernova Ia progenitor candidate.

Matter or mirage? : The public policy rationale for section 9 of the fair trading act 1986 (N.Z.)
Creators: name: Hall, Christopher Brian
Publisher: name: University of British Columbia
Year: 2009

description: The two main points of this thesis are; first, that section 9 of the Fair Trading Act 1986 (New Zealand) has a particular public policy rationale; and, secondly, that, because of drafting inadequacies and of improper approach by the courts, that rationale is not being properly advanced. The first of the writer's theses is that the Act is inadequately drafted. The public policy rationale is identified and seen to be four-fold. The two principal elements are; one, to advance efficiency in the marketplace; and, two, protect consumers, especially those who are less able to protect themselves from the effects of misleading or deceptive conduct. It is determined that efficiency and consumer protection are not always consistent goals but that they are in this particular context of provision of information. It is seen that there are at least three deficiencies in the Act that inhibit promotion of those two limbs of the policy rationale. The writer's second thesis is that the courts have failed to recognise and give effect to the policy rationale for section 9 and have, instead, imported principles developed under the tort of passing off. The public policy rationale for passing off is examined. It is concluded that it primarily owes both its existence and its scope to the interests of traders. The approach of the courts in New Zealand, and those in Australia under their virtually identical section 52 of the Trade Practices Act, is examined and it is seen that passing off principles are imported in at least five areas. The practical effects of the deficiencies in the legislation and in the approach of the courts are identified by a law and economics analysis and by considering nine possible variations of a hypothetical fact example. The result is confirmation that the drafting inadequacies and the approach of the courts together cause reduction of efficiency and disadvantaging of consumers.

description: Soft robotic hands and grippers are increasingly attracting attention as a robotic end-effector. Compared with rigid counterparts, they are safer for human-robot and environment-robot interactions, easier to control, lower cost and weight, and more compliant. Current soft robotic hands have mostly focused on the soft fingers and bending actuators. However, the palm is also essential part for grasping. In this work, we propose a novel design of soft humanoid hand with pneumatic soft fingers and soft palm. The hand is inexpensive to fabricate. The configuration of the soft palm is based on modular design which can be easily applied into actuating all kinds of soft fingers before. The splaying of the fingers, bending of the whole palm, abduction and adduction of the thumb are implemented by the soft palm. Moreover, we present a new design of soft finger, called hybrid bending soft finger (HBSF). It can both bend in the grasping axis and deflect in the side-to-side axis as human-like motion. The functions of the HBSF and soft palm were simulated by SOFA framework. And their performance was tested in experiments. The 6 fingers with 1 to 11 segments were tested and analyzed. The versatility of the soft hand is evaluated and testified by the grasping experiments in real scenario according to Feix taxonomy. And the results present the diversity of grasps and show promise for grasping a variety of objects with different shapes and weights.

description: Induced neurons (iNs) are reprogrammed somatic cells that are forced to change their fate without passing through a pluripotent state, shortening the process of neuronal generation compared to the use of human pluripotent stem cells. The scientific interest in these cells is explained by their suitable use for disease modelling, drug screening and cell therapy for diseases such as Parkinson Disease (PD). Recently, we have developed an all-in-one vector that delivers two factors, Brn2a and Ascl1, together with a REST (RE1-silencing transcription factor) inhibition to successfully generate neurons from both PD patient and control fibroblasts at high efficiencies. An important characteristic of the reprogrammed cells that has to be taken into account to confirm their neuronal identities is their electrophysiological profile. Here, we aim at studying the electrical activity of iNs using the whole cell patch-clamp technique. We first evaluate different culture conditions by testing different coatings to promote an optimal long-term maturation of the iNs, neccessary for electrophysiological maturity. More specifically, we compare Gelatin, Matrigel, laminin 111 and different polyornithine, laminin and fibronectin triple coatings, and found that the later condition provides better plating and long-term survival (>80 days). We further compare our best coating condition with the co-culturing of iNs with either primary rodent astrocytes or neurons. These experiments will allow further assessment of the long-term adult iNs electrical activity, which constitutes an important step towards using iNs for disease modelling of patient-derived cells.

Προκειμένου να επιτευχθούν οι ερευνητικοί στόχοι κρίθηκε αναγκαία η χρήση της συνέντευξης ως εργαλείου για τη συλλογή των δεδομένων. Από την έρευνα που πραγματοποιήσαμε, στην οποία συμμετείχαν 8 ενήλικες ελληνικής πολιτισμικής καταγωγής, προκύπτει η θετική στάση απέναντι στα μέλη μεταναστευτικών ομάδων που ζουν στην Ελλάδα και η διατήρηση κοινωνικών σχέσεων με άτομα που διαφέρουν πολιτισμικά. Παράλληλα, όπως προκύπτει από τις απαντήσεις τους, και τα παιδιά των ντόπιων φαίνεται να διατηρούν σχέσεις με παιδιά από μεταναστευτικές ομάδες. Ταυτόχρονα, όμως, επισημαίνονται από τους συμμετέχοντες τα βασικότερα εμπόδια που συναντιούνται και δυσκολεύουν τη διαπολιτισμική επαφή. Από τα προβλήματα αυτά ξεχωρίζει αυτό της χρήσης διαφορετικής γλώσσας. Τέλος, όσον αφορά στις προτιμώμενες στρατηγικές επιπολιτισμού, οι συμμετέχοντες στην έρευνα φαίνεται να επιλέγουν την στρατηγική της εναρμόνισης, αν και φαίνονται ιδιαίτερα προβληματισμένοι απέναντι στο ζήτημα της δίγλωσσης διδασκαλίας στο ελληνικό σχολείο.
description: The aim of this study is to highlight the perceptions and attitudes of respondents to cultural diversity, the quality and quantity of social interaction of their own and also their children with people who are different culturally, the emotions arising from these contacts, the factors standing obstacle or complicate their relationships and their attitudes towards possible acculturation strategies. In order to achieve the research objectives was necessary to use the interview as a tool for data collection. The investigation we conducted, in which participated 8 native Greek adults, shows a positive attitude towards members of migrant groups living in Greece and maintenance of social relationships with culturally different people. Moreover, as is clear from their responses, also the children of locals appear to maintain relationships with children from immigrant groups. However, at the same time, the participants marked the main obstacles that they encounter and make difficult the cross-cultural contact. The problem that stands out is that of the usage of different language. Finally, with regard to the preferred acculturation strategies, research respondents seem to choose the strategy of integration, although they seem very concerned towards the issue of bilingual teaching at Greek school.

description: Industrial robot manipulators are not able to match the precision and speed with which humans are able to execute contact rich tasks even to this day. Therefore, as a means overcome this gap, we demonstrate generative methods for imitating a peg-in-hole insertion task in a 6-DOF robot manipulator. In particular, generative adversarial imitation learning (GAIL) is used to successfully achieve this task with a 10 um, and a 6 um peg-hole clearance on the Yaskawa GP8 industrial robot. Experimental results show that the policy successfully learns within 20 episodes from a handful of human expert demonstrations on the robot (i.e., < 10 tele-operated robot demonstrations). The insertion time improves from > 20 seconds (which also includes failed insertions) to < 15 seconds, thereby validating the effectiveness of this approach.

Which Stars Form Black Holes and Neutron Stars?

description: I describe the current state of our knowledge of the mapping between the initial masses of stars and the compact objects -- particularly neutron stars and black holes -- that they produce. Most of that knowledge is theoretical in nature, and relies on uncertain assumptions about mass loss through winds, binary mass transfer, and the amount of mass ejected during a supernovae. Observational constraints on the initial masses of stars that produce neutron stars and black holes is scarce. They fall into three general categories: (1) models of the stars that produced the supernova remnants associated with known compact objects, (2) scenarios through with high mass X-ray binaries were produced, and (3) associations between compact objects and coeval clusters of stars for which the minimum masses of stars that have undergone supernovae are known. I focus on the last category as the most promising in the near term. I describe three highly-magnetized neutron stars that have been associated with progenitors that had initial masses of $>$30\msun, and evaluate the prospects of finding further associations between star clusters and compact objects.

description: Natural scene text detection is an important aspect of scene understanding and could be a useful tool in building engaging augmented reality applications. In this work, we address the problem of false positives in text spotting. We propose improving the performace of sliding window text spotters by looking for character pairs (bigrams) rather than single characters. An efficient convolutional neural network is designed and trained to detect bigrams. The proposed detector reduces false positive rate by 28.16% on the ICDAR 2015 dataset. We demonstrate that detecting bigrams is a computationally inexpensive way to improve sliding window text spotters.

The Afterglows and Host Galaxies of Short GRBs: An Overview

Subjects: subject: Astrophysics (astro-ph)

description: Despite a rich diversity in observational properties, gamma-ray bursts (GRBs) can be divided into two broad categories based on their duration and spectral hardness -- the long-soft and the short-hard GRBs. The discovery of afterglows from long GRBs in 1997, and their localization to arcsecond accuracy, was a watershed event. The ensuing decade of intense study led to the realization that long-soft GRBs are located in star forming galaxies, produce about 10^51 erg in collimated relativistic ejecta, are accompanied by supernovae, and result from the death of massive stars. While theoretical arguments suggest that short GRBs have a different physical origin, the lack of detectable afterglows prevented definitive conclusions. The situation changed dramatically starting in May 2005 with the discovery of the first afterglows from short GRBs localized by Swift and HETE-2. Here I summarize the discovery of these afterglows and the underlying host galaxies, and draw initial conclusions about the nature of the progenitors and the properties of the bursts.

description: We present the first observations of magnetic cataclysmic variables with the Spitzer Space Telescope. We used the Infrared Array Camera to obtain photometry of the polars EF Eri, GG Leo, V347 Pav, and RX J0154.0-5947 at 3.6, 4.5, 5.8, and 8.0 $μ$m. In all of our targets, we detect excess mid-infrared emission over that expected from the component stars alone. We explore the origin of this IR excess by examining bremsstrahlung, cyclotron emission, circumbinary dust, and L/T brown dwarf secondary stars. Bremsstrahlung and cyclotron emission appear unlikely to be significant contributors to the observed fluxes. At present, the most likely candidate for the excess emission is dust that is probably located in a circumbinary disk with an inner temperature near 800 K. However, a simple dust disk plus any reasonable low mass or brown dwarf-like secondary star is unable to fully explain the observed flux densities in the 3--8 $μ$m region.

description: We analyze the stellar populations of the Canis Major stellar over-density, using quantitative color-magnitude diagram (CMD) fitting techniques. The analysis is based on photometry obtained with the Wide Field Imager at the 2.2m telescope at La Silla for several fields near the probable center of the over-density. A modified version of the MATCH software package was applied to fit the observed CMDs, enabling us to constrain the properties of the old and young stellar populations that appear to be present. For the old population we find [Fe/H]~-1.0, a distance of ~7.5 kpc and a line-of-sight depth sigma_los of 1.5+-0.2 kpc and a characteristic age range of 3-6 Gyrs. However, the spread in ages and the possible presence of a ~10 Gyr old population cannot be constrained. The young main-sequence is found to have an age spread; ages must range from a few hundred Myr to 2 Gyr. Because of the degeneracy between distance and metallicity in CMDs the estimates of these parameters are strongly correlated and two scenarios are consistent with the data: if the young stars have a similar metallicity to the old stars, they are equidistant and therefore co-spatial with the old stars; if the young stars have close to solar metallicity they are more distant (~9 kpc). The relatively low metallicity of the old main-sequence favors the interpretation that CMa is the remnant of an accreted dwarf galaxy. Spectroscopic metallicity measurements are needed to determine whether the young main-sequence is co-spatial.

description: Abstract

Primary central nervous system lymphoma (PCNSL) is a rare extranodal non-Hodgkin lymphoma confined to the CNS, historically treated with chemotherapy and radiotherapy. Surgery has primarily been limited to biopsy due to the tumor's diffuse nature and sensitivity to chemotherapy. However, recent advancements in neurosurgical techniques have prompted reevaluation of the role of surgery. Select patients with solitary, well-circumscribed lesions or life-threatening mass effects may benefit from surgical intervention. Advances such as minimally invasive techniques, neuronavigation, and fluorescence-guided surgery have enhanced the safety and precision of resections. Integrating surgery with chemotherapy or radiotherapy may improve local control and patient outcomes. Molecular profiling and personalized treatment strategies are being investigated to further refine the role of surgery in PCNSL management. While surgery is not yet a primary treatment, its evolving role offers potential benefits in carefully selected cases.

description: We present a brief overview of nuclear multifragmentation reaction. Basic formalism of canonical thermodynamical model based on equilibrium statistical mechanics is described. This model is used to calculate basic observables of nuclear multifragmentation like mass distribution, fragment multiplicity, isotopic distribution and isoscaling. Extension of canonical thermodynamical model to a projectile fragmentation model is outlined. Application of the projectile fragmentation model for calculating average number of intermediate mass fragments and the average size of largest cluster at different $Z_{bound}$, differential charge distribution and cross-section of neutron rich nuclei of different projectile fragmentation reactions at different energies are described. Application of nuclear multifragmentation reaction in basic research as well as in other domains is outlined.

Plea bargaining : a comparative study of Austrian and Canadian law
Creators: name: Ziegelwanger, Vera
Publisher: name: University of British Columbia

description: This thesis deals with plea bargaining, a method of settling criminal cases without litigation. Plea bargaining is any agreement by the accused to plead guilty in return for the promise of some benefit. While the practice is openly discussed in Canada, little literature exists about this topic in Austria. An analysis of the practice is thus made by comparing the Austrian law enforcement system to the Canadian one. After a comparison of the rules and principles that govern the procedures in both countries, the thesis deals with the problems that are caused by plea bargains. Proponents have said that plea bargaining is a practice that eases the administration of justice without either prejudicing the rights of the innocent or occasioning real injustice to the guilty. The second part of this work thus focuses on the rights of the accused and the rules that are designed to protect him. The defendant who pleads guilty receives mild treatment as a reward for his admission of guilt. Whether or not this is consistent with the public's claim for justice is dealt with in part three of the essay. The method used is an exploration of the goals and purposes of criminal punishment in Austria and Canada. It is shown that plea bargaining not only causes a lack of protection for the accused, it also creates inequality. The practice leads to a goal displacement. In the pursuit of efficiency the original goals of the penal system and the idea of justice are neglected.

description: The processes are investigated by which gas loses its angular momentum during the protogalactic collapse phase, leading to disk galaxies that are too compact with respect to the observations. High-resolution N-body/SPH simulations in a cosmological context are presented including cold gas and dark matter. A halo with quiet merging activity since z~3.8 and with a high spin parameter is analysed that should be an ideal candidate for the formation of an extended galactic disk. We show that the gas and the dark matter have similar specific angular momenta until a merger event occurs at z~2 with a mass ratio of 5:1. All the gas involved in the merger loses a substantial fraction of its specific angular momentum due to tidal torques and falls quickly into the center. Dynamical friction plays a minor role,in contrast to previous claims. In fact, after this event a new extended disk begins to form from gas that was not involved in the 5:1 merger event and that falls in subsequently. We argue that the angular momentum problem of disk galaxy formation is a merger problem: in cold dark matter cosmology substantial mergers with mass ratios of 1:1 to 6:1 are expected to occur in almost all galaxies. We suggest that energetic feedback processes could in principle solve this problem, however only if the heating occurs at the time or shortly before the last substantial merger event. Good candidates for such a coordinated feedback would be a merger-triggered star burst or central black hole heating. If a large fraction of the low angular momentum gas would be ejected as a result of these processes, late-type galaxies could form with a dominant extended disk component, resulting from late infall, a small bulge-to-disk ratio and a low baryon fraction, in agreement with observations.

description: This comprehensive review explores the evolving role of surgery in the management of Primary Central Nervous System Lymphoma (PCNSL), a rare and aggressive form of non-Hodgkin lymphoma confined to the CNS. Historically, surgical intervention has been limited to diagnostic biopsy due to the tumor's diffuse nature and sensitivity to chemotherapy. However, recent advances in neurosurgical techniques and molecular profiling have prompted a reevaluation of surgery's role in PCNSL treatment. This review highlights the potential benefits of surgery in specific cases, such as solitary lesions with significant mass effect or failure of non-invasive diagnostics. It further discusses the integration of surgery with high-dose methotrexate-based chemotherapy and radiotherapy, emphasizing that while surgery may not offer survival benefits in most cases, it can alleviate life-threatening symptoms and enhance treatment efficacy in selected patients. The results suggest that although surgery remains adjunctive to chemotherapy, careful patient selection and advancements in minimally invasive techniques could improve outcomes in well-defined clinical scenarios. Further research is needed to optimize multimodal approaches and refine surgical indications.

description: Primary Central Nervous System Lymphoma (PCNSL) is a rare and aggressive form of extranodal non-Hodgkin lymphoma confined to the central nervous system, accounting for less than 5% of all primary brain tumors. Historically, the role of surgery in the management of PCNSL has been limited to diagnostic biopsies due to the tumor’s responsiveness to high-dose methotrexate-based chemotherapy and its diffuse, infiltrative nature. However, recent advancements in neurosurgical techniques and growing interest in personalized, multimodal treatment approaches have led to renewed exploration of surgery's role in PCNSL. This review provides an in-depth analysis of the evolving role of surgery in PCNSL, focusing on modern indications, patient selection, and the integration of surgery with chemotherapy, radiotherapy, and molecular therapies. While chemotherapy remains the cornerstone of treatment, surgery may offer significant benefits in specific cases, such as for solitary, well-circumscribed lesions or life-threatening mass effects where resection can alleviate elevated intracranial pressure. In rare cases, open craniotomy may be required to obtain a more definitive diagnosis when non-invasive imaging proves inconclusive. Technological advancements, including stereotactic biopsy, endoscopic surgery, and fluorescence-guided surgery (FGS), have enhanced the precision and safety of surgical interventions in PCNSL, allowing for safer resection in cases where surgery is necessary, such as in solitary tumors causing significant neurological deficits. Moreover, the integration of surgery with high-dose methotrexate chemotherapy, targeted radiotherapy, and emerging molecular and genetic profiling offers a promising multimodal treatment strategy for select patients. The review highlights the potential for cytoreductive surgery to improve chemotherapy efficacy by reducing tumor burden, facilitating drug delivery, and improving local control when combined with stereotactic radiosurgery. Recent research into molecular markers, such as MYD88 mutations, provides insight into patient-specific surgical outcomes and prognoses, paving the way for personalized neurosurgical approaches. While gross total resection (GTR) may improve progression-free survival in selected cases, overall survival remains dependent on various factors, including response to chemotherapy and molecular profiles. In conclusion, while surgery is unlikely to replace chemotherapy as the primary treatment for PCNSL, it can play a valuable role in specific cases when integrated with other therapies. Continued research into patient selection, surgical techniques, and personalized treatment approaches will further refine the role of surgery in the evolving landscape of PCNSL management.

description: Active region (AR) 12673 produced many M-class and several X-class flares, one of which being an X9.3 flare, which is recorded as the largest solar flare in solar cycle 24. We studied the evolution of the three-dimensional flare-productive magnetic field within AR 12673, using a time series of nonlinear force-free field extrapolations of every 12 hours from September 4th 00:00 UT to 6th 00:00 UT. Our analysis found that three magnetic flux ropes (MFRs) are formed by September 4th, one of which produced the X9.3 flare on September 6th. One MFR has positive magnetic twist which is a different sign from other two MFRs. Since the temporal evolution of the magnetic flux of the MFR accumulating the positive twist is consistent with the profile of the GOES X-ray flux well observed from September 4th to 6th, we suggest that the formation of the MFR having the positive twist is closely related to the occurrence of the M-class flares including an M5.5 flare. We further found a magnetic null in the magnetic field surrounding the MFRs, in particular, above the MFR having positive twist before the M5.5 flare which is the largest M-flare observed during this period. By comparing with the AIA 1600 angstrom images, we found that the footpoints of the overlying field lines are anchored to the area where the brightening was initially observed. Therefore, we suggest that reconnection induced by the torus instability of the positively twisted MFR at the null possibly drived the M5.5 flare.

description: The effects of feedback from high luminosity radio-loud AGN have been extensively discussed in the literature, but feedback from low-luminosity radio-loud AGN is less well understood. The advent of high sensitivity, high angular resolution, large field of view telescopes such as LOFAR is now allowing wide-area studies of such faint sources for the first time. Using the first data release of the LOFAR Two Metre Sky Survey (LoTSS) we report on our discovery of a population of 195 radio galaxies with 150 MHz luminosities between $3\times10^{22}$ and $1.5\times10^{25}\text{ W Hz}^{-1}$ and total radio emission no larger than 80 kpc. These objects, which we term galaxy-scale jets (GSJ), are small enough to be directly influencing the evolution of the host on galaxy scales. We report upon the typical host properties of our sample, finding that 9 per cent are hosted by spirals with the remainder being hosted by elliptical galaxies. Two of the spiral-hosted GSJ are highly unusual with low radio luminosities and FRII-like morphology. The host properties of our GSJ show that they are ordinary AGN observed at a stage in their life shortly after the radio emission has expanded beyond the central regions of the host. Based on our estimates, we find that about half of our GSJ have internal radio lobe energy within an order of magnitude of the ISM energy so that, even ignoring any possible shocks, GSJ are energetically capable of affecting the evolution of the host. The current sample of GSJ will grow in size with future releases of LoTSS and can also form the basis for further studies of feedback from low-luminosity radio sources.
