description: Το Είναι και Χρόνος (ΕΧ) του Μάρτιν Χάιντεγκερ είναι κατά γενική ομολογία ένα από τα πλέον σημαντικά έργα της ιστορίας της φιλοσοφίας. Τόσο η εξέταση της ιστορίας της φιλοσοφίας μέσα σε αυτό όσο και η τεράστια επίδραση που αυτό άσκησε στη φιλοσοφία που έπεται της εμφάνισής του (1927) το καθιστούν αναγκαία ύλη κάθε αξιόλογου φιλοσοφικού προγράμματος σπουδών. Το έργο αυτό όμως είναι και διαβόητο για τη μεγάλη δυσκολία που παρουσιάζει στην κατανόησή του. Στη συγκεκριμένη ερμηνεία και ανάλυση του ΕΧ, λοιπόν, επιχειρείται η λεπτομερής και διδακτική εξήγηση όλων των ιδεών και των επιχειρημάτων του. Σε αυτό το εγχείρημα δε ακολουθείται ειδικώς μια μεθοδολογία την οποία κρίνω την πιο ενδεδειγμένη: η φαινομενολογική -- το έργο προσεγγίζεται φαινομενολογικά. Ο ίδιος ο Χάιντεγκερ κάνει ρητό πως κάθε τι που πρόκειται να γίνει θέμα στο ΕΧ πρέπει να μπορεί να καθίσταται φαινόμενο. Η απαίτηση αυτή δεν είναι επουσιώδης ή ευκαιριακή. Χαρακτηρίζει το έργο, το σχέδιό του, και την τελική σκόπευσή του σε κάθε σημείο της ανάπτυξης. Ο Χάιντεγκερ αναδεικνύεται ως σχεδόν εμμονικός με αυτό το καθήκον. Επιχειρεί να κάνει φαινομενολογική οντολογία, δηλαδή να διαλευκάνει φαινομενολογικά το μέγιστο και σκοτεινότερο πρόβλημα της φιλοσοφίας από ιδρύσεώς της: το νόημα του Είναι. Κατά τη φαινομενολογική μεθοδολογία, αποκλείεται εξαρχής και κατ’ αρχήν κάθε προσφυγή στην εικασία και τη σκέτη ανάλυση εννοιών (λογική ή διαλεκτική) χωρίς απαραίτητη σύνδεση με μια εποπτεία όπου κάθε τι για το οποίο μιλάμε φανερώνεται το ίδιο ως έχει. Προφανώς, κάτι τέτοιο φαντάζει, σε πρώτη προσέγγιση, σχεδόν τερατώδες. Εδώ βρίσκεται ο πυρήνας της δυσκολίας κατανόησης του ΕΧ. Έτσι, στην εδώ προτεινόμενη ερμηνεία και ανάλυση δίνεται ιδιαίτερη έμφαση στον φωτισμό των προϋποθέσεων της κατανόησης της όλης φιλοσοφικής έρευνας που ο Χάιντεγκερ επιχειρεί στο ΕΧ. Πάνω σε αυτή τη βάση, πραγματοποιείται και η ενδελεχής ανάδειξη όλων των ιδεών και των επιχειρημάτων που περιέχονται στο ΕΧ και ειδικά στην Πρώτη Διαίρεση.

De Finetti methods in quantum information
Creators: name: Borderi, Francesco
Publisher: name: Imperial College London
Year: 2022

description: The main topic of this thesis is the study of de Finetti methods and their applications in quantum information theory. Those methods include de Finetti representation theorems and De Finetti reductions. The primary motivation of a de Finetti representation theorem is to represent, or approximate, a mathematical object symmetric under permutation of its components, into a probabilistic ensemble of elementary independent and identically distributed (i.i.d.) constituents. De Finetti reductions are another class of techniques that are used to take advantage of permutation symmetries. For example, a quantum de Finetti reduction provides an upper bound to a symmetric quantum state in the form of an integral superposition of product states, weighted by a factor that is polynomial in terms of the number of copies and exponential in terms of the local dimensionality. Our findings include: 1- The development of general mathematical techniques that can be used to obtain concrete constrained de Finetti representation theorems for the desired application. 2- The application of those methods to the problem of approximate quantum error correction. In particular, we use our framework to develop asymptotically converging SDP hierarchies that can be used to study the average and worst error cases, as given by the quantum channel fidelity and a channel distance based on the diamond norm, respectively. 3- A new de Finetti reduction in the presence of an additional system carrying side information, that can handle various types of linear constraints. 4- The development of entropic techniques that can be used to generate de Finetti representation theorems from a starting de Finetti reduction. In particular, we use those methods to obtain a new proof for finite quantum de Finetti theorems.

description: We present a fully disclosed tracking pipeline based on mutual capacitance sensing. We designed both hard- and software to support and foster experimentation. Without the use of vendor-supplied cap-sense ICs and proprietary software parts, every aspect and parameter of the user interface can be modified with ease. This flexibility gives the researcher a high degree of freedom while designing novel interactive systems. The working prototype of an audio-tactile multi-touch map is presented as an exemplary application.
Surface photogalvanic effect in Weyl semimetals

description: The photogalvanic effect—a rectified current induced by light irradiation—requires the intrinsic symmetry of the medium to be sufficiently low, which strongly limits candidate materials for this effect. In this paper we explore how in Weyl semimetals the photogalvanic effect can be enabled and controlled by design of the material surface. Specifically, we provide a theory of ballistic linear and circular photogalvanic current in a Weyl semimetal spatially confined to a slab under general and variable surface boundary conditions. The results are applicable to Weyl semimetals with an arbitrary number of Weyl nodes at radiation frequencies small compared to the energy of nonlinear terms in the dispersion at the Fermi level. The confinement-induced response is tightly linked to the configuration of Fermi-arc surface states, specifically the Fermi-arc connectivity and direction of emanation from the Weyl nodes, thus inheriting the same directionality and sensitivity to boundary conditions. As a result, the photogalvanic response of the system becomes much richer than that of an infinite system, and may be tuned via surface manipulations.

description: Sulfidated nanoscale zerovalent iron (S-nZVI) exhibits low anoxic oxidation and high reactivity towards many chlorinated hydrocarbons (CHCs). However, nothing is known about S-nZVI reactivity once exposed to complex CHC mixtures, a common feature of CHC plumes in the environment. Here, three S-nZVI materials with varying iron sulfide (mackinawite, FeSm) shell thickness and crystallinity were exposed to groundwater containing a complex mixture of chlorinated ethenes, ethanes, and methanes. CHC removal trends yielded pseudo-first order rate constants (kobs) that decreased in the order: trichloroethene > trans-dicloroethene > 1,1-dichlorethene > trichloromethane > tetrachloroethene > cis-dichloroethene > 1,1,2-trichloroethane, for all S-nZVI materials. These kobs trends showed no correlation with CHC reduction potentials based on their lowest unoccupied molecular orbital energies (ELUMO) but absolute values were affected by the FeSm shell thickness and crystallinity. In comparison, nZVI reacted with the same CHCs groundwater, yielded kobs that linearly correlated with CHC ELUMO values (R2 = 0.94) and that were lower than S-nZVI kobs. The CHC selectivity induced by sulfidation treatment is explained by FeSm surface sites having specific binding affinities towards some CHCs, while others require access to the metallic iron core. These new insights help advance S-nZVI synthesis strategies to fit specific CHC treatment scenarios.

description: To investigate the imaging performance of an elastin-specific molecular magnetic resonance imaging (MRI) probe with respect to the extracellular matrix (ECM) in an experimental hepatic cancer model. Twelve rabbits with hepatic VX2 tumors were examined using 3 T MRI 14, 21, and 28 days after tumor implantation for two subsequent days (gadobutrol, day 1; elastin-specific probe, day 2). The relative enhancement (RE) of segmented tumor regions (central and margin) and the peritumoral matrix was calculated using pre-contrast and delayed-phase T1w sequences. MRI measurements were correlated to histopathology and element-specific and spatially resolved mass spectrometry (MS). Mixed-model analysis was performed to assess the performance of the elastin-specific probe. In comparison to gadobutrol, the elastin probe showed significantly stronger RE, which was pronounced in the tumor margin (day 14–28: P ≤ 0.007). In addition, the elastin probe was superior in discriminating between tumor regions (χ2(4) = 65.87; P

description: The use of contextual information is an important capability to facilitate language comprehension. This can be shown by studying behavioral and neurophysiological measures of accelerated word recognition when semantically or phonemically related information is provided in advance, resulting in accompanying attenuation of the respective event-related potential, i.e. the N400 effect. Against the background of age-dependent changes in a broad variety of lexical capacities, we aimed to study whether word priming is accomplished differently in elderly compared to young persons. 19 young (29.9 ± 5.6 years) and 15 older (69.0 ± 7.2 years) healthy adults participated in a primed lexical decision task that required the classification of target stimuli (words or pseudo-words) following related or unrelated prime words. We assessed reaction time, task accuracy and N400 responses. Acceleration of word recognition by semantic and phonemic priming was significant in both groups, but resulted in overall larger priming effects in the older participants. Compared with young adults, the older participants were slower and less accurate in responding to unrelated word-pairs. The expected N400 effect was smaller in older than young adults, particularly during phonemic word and pseudo-word priming, with a rather similar N400 amplitude reduction by semantic relatedness. The observed pattern of results is consistent with preserved or even enhanced lexical context sensitivity in older compared to young adults. This, however, appears to involve compensatory cognitive strategies with higher lexical processing costs during phonological processing in particular, suggested by a reduced N400 effect in the elderly.

description: Objective: Critical illness polyneuropathy (CIP) is a common complication of severe systemic illness treated in intensive care medicine. Ischemic stroke leads to an acute critical injury of the brain with hemiparesis, immunosuppression and subsequent infections, all of which require extended medical treatment. Stroke-induced sarcopenia further contributes to poor rehabilitation and is characterized by muscle wasting and denervation in the paralytic, but also the unaffected limbs. Therefore, we asked whether stroke leads to an additional CIP-like neurodegeneration. Results: Focal brain ischemia was induced in adult mice by 60-min middle cerebral artery occlusion (MCAo) following reperfusion and led to functional deficits and marked hemispheric brain atrophy. Nerve conduction function and muscle potentials were measured in the ipsilateral sciatic nerve and gastrocnemius and quadriceps muscle with electroneurography/-myography on days 10, 22, 44 after stroke. An additional crush-injury to the sciatic nerve was included in two sham mice as positive control (sham +). We found no differences in nerve conduction function nor spontaneous electromyographic activity between MCAo and sham animals. Sham + mice developed marked reduction of the motor action potential amplitudes and conduction velocities with pathologic spontaneous activity. In conclusion, we found no peripheral nerve dysfunction/degeneration as signs of a CIP-like phenotype after MCAo.

description: Lameness is one of the most challenging problems in the dairy industry. Control is impeded because farmers often underestimate the number of lame cows. The objectives of this study were to assess German farmers' awareness of lameness in their herds and to determine the associations between farmers' awareness and their management practices, farm characteristics as well as with farmers' education, personality traits and attitudes. As a part of a large cross-sectional study, veterinarians visited farms in three structurally different regions of Germany: north (n = 253), east (n = 252), and south (n = 260). The cows (n = 84,998) were scored for locomotion and farmers were asked to estimate the number of cows that were lame or did not walk soundly. The ratio of farmers' estimated prevalence and the veterinarians' observed prevalence (Farmer's Detection Index; FDI) was calculated. The median lameness prevalence assessed by the veterinarians was 23.1, 39.1, and 23.2%, and the median prevalence of lame cows estimated by the farmers was 9.5, 9.5, and 7.1% in the north, east, and south, respectively. On average, farmers were conscious of only 45.3% (north), 24.0% (east), and 30.0% (south) of their lame cows. Farmers managing their herds according to organic principles had a higher FDI than farmers who managed their herds conventionally. Surprisingly, no significant associations between FDI and factors concerning claw health management could be detected. Therefore, increased awareness did not seem to be necessarily linked to improved management. Moreover, the FDI was not significantly associated with farmers' education or herd size. In the south, more extraverted farmers had a lower FDI. Those farmers who totally agreed with the statement, “I am satisfied with my herd's health,” had a lower FDI than farmers who disagreed or were undecided. Moreover, farmers who disagreed or were undecided with the statement, “It affects me to see a cow in pain” had a higher FDI than those farmers who agreed to the statement. The results indicate that poor awareness of lameness was linked to the farmers' attitude and personality. Therefore, new approaches concerning the consultation regarding lameness control, such as the use of Motivational Interviewing, might be useful in the future.

description: Cognitive resources contribute to balance control. There is evidence that mental fatigue reduces cognitive resources and impairs balance performance, particularly in older adults and when balance tasks are complex, for example when trying to walk or stand while concurrently performing a secondary cognitive task. We conducted a systematic literature search in PubMed (MEDLINE), Web of Science and Google Scholar to identify eligible studies and performed a random effects meta-analysis to quantify the effects of experimentally induced mental fatigue on balance performance in healthy adults. Subgroup analyses were computed for age (healthy young vs. healthy older adults) and balance task complexity (balance tasks with high complexity vs. balance tasks with low complexity) to examine the moderating effects of these factors on fatigue-mediated balance performance. We identified 7 eligible studies with 9 study groups and 206 participants. Analysis revealed that performing a prolonged cognitive task had a small but significant effect (SMDwm = −0.38) on subsequent balance performance in healthy young and older adults. However, age- and task-related differences in balance responses to fatigue could not be confirmed statistically. Overall, aggregation of the available literature indicates that mental fatigue generally reduces balance in healthy adults. However, interactions between cognitive resource reduction, aging and balance task complexity remain elusive.

description: Taenia (T.) solium is a zoonotic parasite causing three diseases: Taeniasis and cysticercosis in humans and porcine cysticercosis in pigs. Although biomedically, the transmission of the parasite can be easily interrupted at six points along the life cycle, the contextual factors that may influence the adoption of these control strategies in Uganda remain unclear. This study assessed the stakeholders' knowledge, attitudes, and perceptions relating to the six control strategies for T. solium infections in Kamuli and Hoima districts, Uganda. A total of 22 focus group discussions (FGD) were conducted with pig farmers, community leaders, pig/pork traders, animal health assistants, and human health assistants. In addition, nine key informant interviews were held with senior officials in the ministries of agriculture and health and other relevant agencies at the district level. The results showed differential, limited, and fragmented knowledge on T. solium infections among stakeholders. Pig farmers, community leaders, and pig/pork traders had almost no knowledge and were often confused regarding the differences existing between T. solium and other gastro-intestinal infections in pigs and humans. Pig confinement, pit latrine construction, coverage, maintenance, and sustained use are influenced by cultural, socio-economic, and physical/ environmental factors of the study population and area. Proper sensitisation programmes and health education interventions should target all, but with appropriately focused material to suit the different stakeholder categories. Reminders or nudges may be needed to ensure that increase in knowledge translates to changes in practise. Intervention programmes should also aim to overcome challenges created by the various contextual factors operating in the specific endemic areas.

description: Nitrogen doping carbon nanotubes can enhance their beneficial physical and chemical properties, rendering them more desirable for various applications, e.g., in electronics. In this study, we used catalytic chemical vapor deposition to synthesize carbon na-no-tube forests on different substrates. The samples were prepared in the presence of compounds containing nitrogen (ammonia, acetonitrile, tripropylamine, and their mixture with acetone) that were introduced into the reactor by bubbling or injection. Of the two different nitrogen introduction methods, the direct injection of a liquid nitrogen precursor promoted the synthesis of bamboo-structured carbon nanotube forests more efficiently. It was found in the injection experiments that the amount of precursor affected the extent of nitrogen incorporation. The presence of various nitrogen species in CNTs was also identified, and the manner in which temperature and the presence of hydrogen both influence nitrogen incorporation into the carbon na-no-tubes was observed.

We recruited 32 participants who were active smokers (n=15) or vapers (n=17) and performed a total of 39 measurements before and 5, 15, and 30 minutes, after participants smoked a combustible cigarette or vaped a JUUL e-cigarette with the new or old technology. Measurements included peripheral and central blood pressures and parameters of arterial stiffness, including pulse wave velocity and augmentation index. Results: Peripheral systolic blood pressure, central blood pressure, and peripheral pulse rate increased significantly in all three groups (each p<0.05). Heart rate (HR) changes lasted significantly longer than blood pressure changes. The augmentation index and pulse wave velocity increased in all three groups, and a multivariate analysis of variance showed that the increases were independent of systolic blood pressure, sex, age, device, and HR. Conclusions: Changes in blood pressure and arterial stiffness are similar after cigarette smoking and JUUL use. These changes may be associated with an increased cardiovascular risk compared with no product use. However, a longterm follow-up evaluation of JUUL use and a head-to-head comparison with conventional e-cigarettes are still needed.

description: Glucose hypometabolism potentially contributes to Alzheimer’s disease (AD) and might even represent an underlying mechanism. Here, we investigate the relationship of diet-induced metabolic stress and AD as well as the therapeutic potential of chia seeds as a modulator of glucose metabolism in the APP23 mouse model. 4–6 (pre-plaque stage, PRE) and 28–32 (advanced-plaque stage, ADV) weeks old APP23 and wild type mice received pretreatment for 12 weeks with either sucrose-rich (SRD) or control diet, followed by 8 weeks of chia seed supplementation. Although ADV APP23 mice generally showed functioning glucose homeostasis, they were more prone to SRD-induced glucose intolerance. This was accompanied by elevated corticosterone levels and mild insulin insensitivity. Chia seeds improved spatial learning deficits but not impaired cognitive flexibility, potentially mediated by amelioration of glucose tolerance, attenuation of corticosterone levels and reversal of SRD-induced elevation of pro-inflammatory cytokine levels. Since cognitive symptoms and plaque load were not aggravated by SRD-induced metabolic stress, despite enhanced neuroinflammation in the PRE group, we conclude that impairments of glucose metabolism do not represent an underlying mechanism of AD in this mouse model. Nevertheless, chia seeds might provide therapeutic potential in AD as shown by the amelioration of cognitive symptoms.

description: In patients with aortic coarctation it would be desirable to assess pressure gradients as well as information about blood flow profiles at rest and during exercise. We aimed to assess the hemodynamic responses to physical exercise by combining MRI-ergometry with computational fluid dynamics (CFD). MRI was performed on 20 patients with aortic coarctation (13 men, 7 women, mean age 21.5 ± 13.7 years) at rest and during ergometry. Peak systolic pressure gradients, wall shear stress (WSS), secondary flow degree (SFD) and normalized flow displacement (NFD) were calculated using CFD. Stroke volume was determined based on MRI. On average, the pressure gradient was 18.0 ± 16.6 mmHg at rest and increased to 28.5 ± 22.6 mmHg (p

description: In der vorliegenden Habilitationsschrift wurden die Inhalte von fünf wissenschaftlichen Arbeiten zu dem Thema 4D Fluss MRT bei kardiovaskulären Erkrankungen vorgestellt. Es erfolgte zunächst die Validierung der 4D Fluss MRT Methode und daraufhin deren Anwendung bei Patienten mit partieller Lungenvenenfehlmündung und Patienten mit univentrikulärer Anatomie. Des Weiteren wurde die Verbesserung der diagnostischen Möglichkeit bei komplexen Flussprofilen durch die 4D Fluss MRT Methode und die Vorhersage von postoperativen Flussgeschwindigkeiten und -profilen nach Aortenklappenersatz unter Verwendung von 4D Fluss MRT basierten numerischen Strömungsanalysen (CFD) beschrieben. Die 4D Fluss MRT Methode hat somit das Potenzial, gezielte klinische Anwendung bei kardiovaskulären Erkrankungen zu finden, die Diagnostik zu verbessern und dazu beizutragen, Therapien und somit Therapieergebnisse zu optimieren.

description: Radiographs are the clinical first line imaging modality for evaluating hip morphology and pathology. MRI offers additional information and is the method of choice to evaluate soft tissue, bone marrow and preradiographic signs of osteoarthritis. Radiographs are used to measure the most morphometric parameters. The aim of this study was to compare susceptibility weighted MRI (SWMR) with radiographs to evaluate hip morphology. 40 Patients were examined with standard MR-sequences, coronal SWMR and radiographs in anteroposterior pelvic view. Coronal maximum intensity projection (MIP) images of both hips were automatically reconstructed on SWMR and T1weighted images. Sharp´s angle, Tönnis angle, lateral center–edge angle of Wiberg and caput-collum-diaphyseal angle were measured on coronal SWMR MIP-images, T1weighted MIP-images and radiographs. Measurements were compared by linear regression analysis and Bland-Altmann Plots, using radiographs as reference standard. Additionally, a ratio between the signal intensity of muscles and bone on SWMR and T1weighted MIP-images was calculated and compared between these two sequences. SWMR enables the reliable assessment of Sharp´s angle (SWMR: R2 = 0.80; T1weighted: R2 = 0.37), Tönnis angle (SWMR: R2 = 0.86; T1weighted: not measurable), lateral center–edge angle of Wiberg (SWMR: R2 = 0.88; T1weighted: R2 = 0.40) and caput-collum-diaphyseal angle (SWMR: R2 = 0.38; T1weighted: R2 = 0.18) compared to radiographs with a higher accuracy than conventional MR imaging. The ratio between the intensity of muscles and bone was significant higher on SWMR (2.00 and 2.02) than on T1weighted MIP-images (1.6 and 1.42; p

description: Nanoindentation technology with high spatial resolution and force sensitivity is widely used to measure the mechanical properties of hard biomaterials and tissues. However, its reliability to analyze soft biomaterials and organs has not been tested. Here, we evaluated the utility of nanoindentation to measure the passive mechanical properties of soft biological specimen. Kidney, liver, spleen and uterus samples were harvested from C57BL/6 N mice. We assessed test–retest repeatability in biological specimen and hydrogel controls using Bland–Altman diagrams, intraclass correlation coefficients (ICCs) and the within-subject coefficients of variation (COVs). The results were calculated using Hertzian, JKR and Oliver & Pharr models. Similar to hydrogels, Bland–Altman plots of all biological specimen showed good reliability in stiffness test and retest examinations. In gels, ICCs were larger than 0.8 and COVs were smaller than 15% in all three models. In kidney, liver, spleen and uterus, ICCs were consistently larger than 0.8 only in the Hertzian model but not in the JKR and Oliver & Pharr models. Similarly, COVs were consistently smaller than 15% in kidney, liver, spleen and uterus only in the Hertzian model but not in the other models. We conclude that nanoindentation technology is feasible in detecting the stiffness of kidney, liver, spleen and uterus. The Hertzian model is the preferred method to provide reliable results on ex vivo organ stiffness of the biological specimen under study.

description: Background: Although considered complex and challenging, esophagectomy remains the best potentially curable treatment option for resectable esophageal and esophagogastric junction (AEG) carcinomas. The optimal surgical approach and technique as well as the extent of lymphadenectomy, particularly regarding quality of life and short- and long-term outcomes, are still a matter of debate. To lower perioperative morbidity, we combined the advantages of a one-cavity approach with extended lymph node dissection (usually achieved by only a two-cavity approach) and developed a modified single-cavity transhiatal approach for esophagectomy. Methods: The aim of this study was to evaluate the outcome of an extended transhiatal esophageal resection with radical bilateral mediastinal en bloc lymphadenectomy (eTHE). A prospective database of 166 patients with resectable cancers of the esophagus (including adenocarcinomas of the AEG types I and II) were analyzed. Patients were treated between 2001 and 2017 with eTHE at a tertiary care university center. Relevant patient characteristics and outcome parameters were collected and analyzed. The primary endpoint was 5-year overall survival. Secondary outcomes included short-term morbidity, mortality, radicalness of en bloc resection and oncologic efficacy. Results: The overall survival rates at 1, 3 and 5 years were 84, 70, and 61.0%, respectively. The in-hospital mortality rate after eTHE was 1.2%. Complications with a Clavien-Dindo score of III/IV occurred in 31 cases (18.6%). A total of 25 patients (15.1%) had a major pulmonary complication. The median hospital stay was 17 days (interquartile range (IQR) 12). Most patients (n = 144; 86.7%) received neoadjuvant treatment. The median number of lymph nodes resected was 25 (IQR 17). The R0 resection rate was 97%. Conclusion: In patients with esophageal cancer, eTHE without thoracotomy resulted in excellent long-term survival, an above average number of resected lymph nodes and an acceptable postoperative morbidity and mortality.

description: Τα συστήματα συστάσεων χρησιμοποιούνται ευρέως στις πλατφόρμες ψυχαγωγίας και στις επιχειρήσεις ηλεκτρονικού εμπορίου για την εξατομίκευση της εμπειρίας των χρηστών και τη βελτίωση της ικανοποίησης των πελατών. Ωστόσο, αντιμετωπίζουν σημαντικές προκλήσεις, όπως το πρόβλημα της αραιότητας των δεδομένων, όπου τα δεδομένα αλληλεπίδρασης είναι αραιά, και το πρόβλημα της ψυχρής εκκίνησης (cold start), όπου νέοι χρήστες ή αντικείμενα δεν έχουν επαρκή δεδομένα αλληλεπίδρασης ώστε οι αλγόριθμοι που παράγουν συστάσεις να εκπαιδευθούν και να αποδώσουν ικανοποιητικά. Η μεταφορά γνώσης αποτελεί μια προσέγγιση μηχανικής μάθησης, η οποία αξιοποιεί τη γνώση που αποκτάται από την επίλυση ενός προβλήματος για την ενίσχυση της λύσης ενός διαφορετικού αλλά σχετικού προβλήματος. Η εφαρμογή τεχνικών μεταφοράς γνώσης σε συστήματα συστάσεων αποσκοπεί στην αντιμετώπιση των ζητημάτων που αντιμετωπίζουν οι παραδοσιακές προσεγγίσεις επιτρέποντας την εκπαίδευση μοντέλων με λιγότερα δεδομένα και με βελτιωμένη απόδοση. Στην παρούσα διπλωματική εργασία διερευνάται η εφαρμογή της μεταφοράς μάθησης σε συστήματα συστάσεων συνεργατικού φιλτραρίσματος με μη-επικαλυπτόμενες οντότητες. Πιο συγκεκριμένα, η μελέτη επικεντρώνεται σε σενάρια όπου δεν υπάρχουν κοινοί χρήστες ή αντικείμενα μεταξύ των τομέων, χρησιμοποιώντας μόνο τις αξιολογήσεις των χρηστών για τη μεταφορά γνώσης, χωρίς να γίνει χρήση μεταδεδομένων. Οι τομείς που χρησιμοποιούνται είναι Ταινίες και Βιβλία και τα πειραματικά αποτελέσματα αξιολογούνται με βάση την ακρίβεια της προτεινόμενης μεθόδου σε σύγκριση με παραδοσιακές τεχνικές συστάσεων που δεν κάνουν χρήση μεταφοράς γνώσης. Αν και ο προτεινόμενος αλγόριθμος έδειξε ότι μπορεί να βελτιώσει τις συστάσεις και να μεταφέρει θετικά γνώση υπό συγκεκριμένες συνθήκες, δεν ήταν αρκετός για να ξεπεράσει σε απόδοση όλες τις παραδοσιακές μεθόδους με τις οποίες συγκρίθηκε και συγκεκριμένα την μέθοδο SVD (singular value decomposition).
