A VLSI receiver architecture for high speed ATM computer networks
Creators: name: Chow, Jeffrey
Publisher: name: University of British Columbia
Year: 2009

description: Network communication bandwidths are surpassing the computational power of host systems. This improvement in communications bandwidth creates a need to develop ded icated communications processors which service the network without serious degradation of throughput. Asynchronous Transfer Mode(ATM) is a new Broadband Integrated Services Digital Network(BISDN) protocol specified to operate over fibre lines at rates of 155 Mbps or 622 Mbps. As the high-speed ATM networking protocol gains widespread acceptance in the networking community, dedicated high-speed protocol processing hardware is required to process ATM’s small 53 byte cells. In ATM networks, the problem of reassembly of cells at network speeds on the receiver side, is of particular significance. The Adaptation Layer is responsible for cell reassembly. In this thesis, a VLSI architecture for ATM receiver adap tation layer processing is presented. A fine grained parallel architecture is employed in our receiver design. Improvements over other ATM receiver designs have been made in our de sign. Potential bottlenecks in existing designs have been identified and an effort is made to overcome these problems. Problems such as parallel CRC computation, fast Virtual Circuit Identifier (VCI) mapping, and effective memory architectures are resolved. The proposed design is shown to operate at high throughputs ranging from 264.46 Mbps to well over 622 Mbps for sustained network data. The design is modelled at two levels so that low level timing details can be determined and high level traffic behavior can be monitored.

description: Using the Swift data of GRB 050315, we progress on the uniqueness of our theoretically predicted Gamma-Ray Burst (GRB) structure as composed by a proper-GRB (P-GRB), emitted at the transparency of an electron-positron plasma with suitable baryon loading, and an afterglow comprising the so called "prompt emission" as due to external shocks. Thanks to the Swift observations, the P-GRB is identified and for the first time we can theoretically fit detailed light curves for selected energy bands on a continuous time scale ranging over 10^6 seconds. The theoretically predicted instantaneous spectral distribution over the entire afterglow is presented, confirming a clear hard-to-soft behavior encompassing, continuously, the "prompt emission" all the way to the latest phases of the afterglow.

description: Κύριο θέμα μελέτης της εν λόγω διπλωματικής εργασίας είναι η πορεία του ελληνικού τύπου από το 1936 έως το 1974 καθώς και η επιβολή λογοκρισίας σε αυτόν κατά την περίοδο των δύο δικτατοριών στην Ελλάδα, εκείνης του Ιωάννη Μεταξά και εν συνεχεία των Συνταγματαρχών. Αρχικά εξετάστηκε η χρονική περίοδος από το 1784 έως το 1936 και τυχόν φαινόμενα λογοκρισίας κατά την περίοδο αυτή. Εν συνεχεία, ερευνήθηκε η περίοδος της δικτατορίας του Μεταξά, η φίμωση του τύπου και η επιβολή προληπτικής λογοκρισίας από τον δικτάτορα. Έγινε δε αναφορά στην περίοδο της κατοχής και στην παρουσία του τύπου κατά τη διάρκεια των ετών από το 1941 έως το 1944. Ακολούθως, εξετάστηκε η περίοδος της καχεκτικής δημοκρατίας και ο ρόλος του τύπου κατά την ως άνω περίοδο. Τέλος, αντικείμενο μελέτης αποτέλεσε και η επιβολή λογοκρισίας στο τύπο κατά την περίοδο της δικτατορίας των Συνταγματαρχών και τα μέτρα τα οποία πάρθηκαν από τις εκάστοτε Κυβερνήσεις. Προκειμένου δε να προκύψουν ασφαλή συμπεράσματα, πραγματοποιήθηκε συγκριτική ανάλυση ανάμεσα στις δύο προαναφερθείσες δικτατορίες, με σκοπό να εντοπισθούν ομοιότητες και διαφορές αναφορικά με τη λειτουργία του τύπου κατά τη διάρκεια και των δύο καθεστώτων
description: The main study subject of dissertation is the course of Greek press from 1936 to 1944 as well as the enforcement of censorship during the period of two dictatorships in Greece, that of Ioannis Metaxas and the dictatorship of the Colonels. Initially was examined the time period from 1784 to 1936 and any apparent censorship phenomenon during this period. Following, object of this search was the dictatorship of Ioannis Metaxas, the censorship and the enforcement of censorship in advance by the dictator. Furthermore, the period of warfare was mentioned as well as the presence of press from 1941 to 1944. Following, was examined the period of controlled democracy and the role of press during this period. Finally, object of the study was the enforcement of censorship on press during the dictatorship of the Colonels and the measures were taken by each time governments. In order to be arisen safe conclusions, a comparative analysis was held between the mentioned above dictatorships in order to be found similarities and differences concerning the press during both regimes

description: We report on how different cluster deposition regimes can be obtained and observed by in situ Scanning Tunneling Microscopy (STM) by exploiting deposition parameters in a pulsed laser deposition (PLD) process. Tungsten clusters were produced by nanosecond Pulsed Laser Ablation in Ar atmosphere at different pressures and deposited on Au(111) and HOPG surfaces. Deposition regimes including cluster deposition-diffusion-aggregation (DDA), cluster melting and coalescence and cluster implantation were observed, depending on background gas pressure and target-to-substrate distance which influence the kinetic energy of the ablated species. These parameters can thus be easily employed for surface modification by cluster bombardment, deposition of supported clusters and growth of films with different morphologies. The variation in cluster mobility on different substrates and its influence on aggregation and growth mechanisms has also been investigated.

Για το σκοπό αυτό επιλέχθηκε να χρησιμοποιηθεί ένα μοντέλο Γραμμικού Προγραμματισμού με στόχο τη μεγιστοποίηση του κέρδους, αλλά και παράλληλη μελέτη άλλων δεικτών που σχετίζονται με την παραγωγή όπως το κόστος, η εργασία και η χρήση λιπασμάτων που είναι σε άμεση συσχέτιση με το περιβάλλον. Ταυτόχρονα, γίνεται μια τεχνικοοικονομική ανάλυση για την εύρεση του άριστου σχεδίου παραγωγής με τον κατάλληλο συνδυασμό των υπαρχόντων συντελεστών. Τα αποτελέσματα που προκύπτουν από την επίλυση του μοντέλου του Γραμμικού Προγραμματισμού είναι πως η πράσινη ενίσχυση επηρεάζει θετικά το εισόδημα των γεωργών της περιοχής με ταυτόχρονη μείωση του κόστους, των ωρών εργασίας και της χρήσης λιπασμάτων. Τα αποτελέσματα αυτά αφορούν το έτος 2015 που είναι και η πρώτη χρονιά ολοκληρωμένης εφαρμογής του μέτρου και αποτελούν μια βάση για περαιτέρω μελέτη τόσο για τις οικονομικές επιπτώσεις του μέτρου σε βάθος χρόνου, όσο και για μελέτη τον επιπτώσεων του μέτρου αυτού σε ευρύτερη περιοχή
description: The main purpose of this dissertation is to study the economic impacts of the greening measurement of the new CAP (2014-2020) in the area of Pella's Regional Unit for all the main arable crops. The model used is Linear Programming in order to maximize profit but also study other production-related indicators such as cost, work and use of fertilizers that are directly related to the environment. At the same time, a technical and economical analysis is made to find an excellent production plan with the appropriate combination of existing factors. The results from the implementation of the methodology are that greening positively affects the income of farmers in the area while reducing costs, working hours and the use of fertilizers. These results relate to the year 2015, which is also the first year of integrated implementation of the measure, and provide a basis for further study of both the economic impact of the measure over time and the impact of this measure on a wider area

description: Scaling data storage is a significant concern in enterprise systems and Storage Area Networks (SANs) are deployed as a means to scale enterprise storage. SANs based on Fibre Channel have been used extensively in the last decade while iSCSI is fast becoming a serious contender due to its reduced costs and unified infrastructure. This work examines the performance of iSCSI with multiple TCP connections. Multiple TCP connections are often used to realize higher bandwidth but there may be no fairness in how bandwidth is distributed. We propose a mechanism to share congestion information across multiple flows in ``Fair-TCP'' for improved performance. Our results show that Fair-TCP significantly improves the performance for I/O intensive workloads.

description: Stimulated by the exciting progress in experiments, we carry out a combined analysis of the masses, and strong and radiative decay properties of the $B$ and $B_s$-meson states up to the second orbital excitations. Based on our good descriptions of the mass and decay properties for the low-lying well-established states $B_1(5721)$, $B_2^*(5747)$, $B_{s1}(5830)$ and $B_{s2}^*(5840)$, we give a quark model classification for the high mass resonances observed in recent years. It is found that (i) the $B_{J}(5840)$ resonance may be explained as the low mass mixed state $B(|SD\rangle_L)$ via $2^3S_1$-$1^3D_1$ mixing, or the pure $B(2^3S_1)$ state, or $B(2^1S_0)$. (ii) The $B_J(5970)$ resonance may be assigned as the $1^3D_3$ state in the $B$ meson family, although it as a pure $2^3S_1$ state cannot be excluded. (iii) The narrow structure around 6064 MeV observed in the $B^+K^-$ mass spectrum at LHCb may be mainly caused by the $B_{sJ}(6109)$ resonance decaying into $B^{*+}K^-$, and favors the assignment of the high mass $1D$-wave mixed state $B_s(1D'_2)$ with $J^P=2^-$, although it as the $1^3D_3$ state cannot be excluded. (iv) The relatively broader $B_{sJ}(6114)$ structure observed at LHCb may be explained with the mixed state $B_s(|SD\rangle_H)$ via $2^3S_1$-$1^3D_1$ mixing, or a pure $1^3D_1$ state. Most of the missing $1P$-, $1D$-, and $2S$-wave $B$- and $B_s$-meson states have a relatively narrow width, they are most likely to be observed in their dominant decay channels with a larger data sample at LHCb.

Talking back: six first nations women’s recovery stories from childhood sexual abuse and addictions
Creators: name: Herbert, Elaine I.
Publisher: name: University of British Columbia
Year: 2009

description: The purpose of this study was to create a discourse or "women's talk" about recovery that embodied and reflected the life experience of six First Nations women who had experienced childhood sexual abuse and addictions. An exploratory, emancipatory, feminist qualitative research design elicited rich, thick data through interactive audio-taped interview processes. The six stories were translated into four emergent themes with 12 sub-themes in the data analysis, as follows: (1) Alcohol Abuse and Addictions; (a) parental/community alcoholism; (b) understanding own alcoholism/getting treatment; (2) Sexual Abuse; (1) incident(s)/experiences of sexual abuse; (b) family/community response to the sexual abuse; (c) effects of the sexual abuse; (3) Recovery Process; (a) recovery as an individual process; (b) spirituality in recovery; (c) racism; (4) Gender Issues; (a) internal perceptions of self as woman; (b) family/community perceptions of the role of women. The women in this study "talked back" with defiance and courage as they recounted their experiences of abuse and addictions, and how they were able to recovery despite the cultural/societal oppression experienced. This First Nations women-centered discourse, which placed culture and gender as major considerations for women in recovery, provides the basis of discussion for creating meaningful intervention and for future research projects.
Quantum Thought Experiments Can Define Nature

description: One would not think that thought experiments could matter to nature, for they are a humble human device. Yet quantum mechanics very naturally frames thought experiments (as distinct from precisely defining what exists). They exemplify the informing powers of radiation. Though based on wave functions that have time symmetry, these tableaux inevitably tell of irreversible behavior by nature. The paper sketches how John von Neumann's measurement theory fits into this and retells N. David Mermin's baseball story.

description: This article presents our procedure to measure the quantum state of a dc SQUID within a few nanoseconds, using an adiabatic dc flux pulse. Detection of the ground state is governed by standard macroscopic quantum theory (MQT), with a small correction due to residual noise in the bias current. In the two level limit, where the SQUID constitutes a phase qubit, an observed contrast of 0.54 indicates a significant loss in contrast compared to the MQT prediction. It is attributed to spurious depolarization (loss of excited state occupancy) during the leading edge of the adiabatic flux measurement pulse. We give a simple phenomenological relaxation model which is able to predict the observed contrast of multilevel Rabi oscillations for various microwave amplitudes.

description: We solve a model of self-avoiding walks with up to two monomers per site on the Bethe lattice. This model, inspired on the Domb-Joyce model, was recently proposed to describe the collapse transition observed in interacting polymers [J. Krawczyk et al, Phys. Rev. Lett. 96, 240603 (2006)]. When immediate self-reversals are allowed (RA model), the solution displays a phase diagram with a polymerized phase and a non-polymerized phase, separated by a phase transition which is of first order for a non-vanishing statistical weight of doubly occupied sites. If the configurations are restricted forbidding immediate self-reversals (RF model), a richer phase diagram is found, displaying a tricritical point and a critical endpoint.

description: In order to study the structure of neutralino star and dark galaxy, we consider dynamical interactions due to boson-exchange in the neutralino matter. Taking into account interactions of neutralinos with bosons, we derive the equation of state (EOS) of neutralino stars in terms of the relativistic mean field approach. Then we apply the resulting EOS to investigate properties of the neutralino star such as its density profile and mass limit. For example, if the neutralino mass is around 1 TeV, the Oppenheimer mass limit of the neutralino star is obtained as $6.06\times 10^{-7}M_\odot$, and the corresponding radius is about 7.8 mm. Actually, due to an increasing annihilation rate as indicated by our calculation, this dense state can never be realized in practice. Our results also show that the low density neutralino star may be a possible aggregation of the cold dark matter.

description: The cache ping-pong problem arises often in parallel processing systems where each processor has its own local cache and employs a copy-back protocol for the cache coherence. To solve the problem of large amounts of data moving back and forth between the caches in different processors, techniques associated with parallel compilers need to be developed. Based on the concept in [Fang, J. Z., Proc. International Conference on Parallel Processing, Aug.1990, pp. 11-271-R-275] regarding the relations between array element accesses and enclosed loop indices in nested parallel loops, we present an algorithm in this paper to reduce the unnecessary data movement between the caches for parallel loops with multiple array subscript expressions. By analyzing the array subscriptexpressions in the nested parallel loop constructs, the compilers can use the algorithm to prepare information at compile time and let the processor execute the corresponding iterations of parallel loops in terms of the data in its cache. It benefits the parallel programs in which parallel loops are enclosed by a sequential loop and have multiple different subscript expressions for the same array, whose elements are repeatedly used in the differentiterations of the outermost sequential loop.

description: In the fermionic systems with topologically stable Fermi points the emergent two - component Weyl fermions appear. We propose the topological classification of these fermions based on the two invariants composed of the two - component Green function. We define these invariants using Wigner - Weyl formalism also in case of essentially non - homogeneous systems. In the case when values of these invariants are minimal ($\pm 1$) we deal with emergent relativistic symmetry. The emergent gravity appears, and our classification of Weyl fermions gives rise to the classification of vierbein. Transformations between emergent relativistic Weyl fermions of different types correspond to parity conjugation, time reversal, and charge conjugation.

description: Lu, M. and X. Qiao, Applying parallel computer systems to solve symmetric tridiagonal eigenvalue problems,Parallel Computing 18 (1992) 1301-1315.
A block parallel partitioning method for computing the eigenvalues of symmetric tridiagonal matrix ispresented. The algorithm is based on partitioning, in a way that ensures load balance during computation. Thismethod is applicable to both shared memory and distributed memory-MIMD systems. Compared with other parallel tridiagonal eigenvalue algorithms existing in the literature, the proposed algorithm achieves a higher speedup of O(p) on a parallel computer with p-fold parallelism, which is linear, and the data communication between processors is less than that required for other methods. The results were tested and evaluated on an MIMD machine, and were within 62% to 98% of the predicted performance.
Immunological and molecular characterization of the STX-10 antigen
Creators: name: Hsiao, Letticia
Publisher: name: University of British Columbia
Year: 2009

description: The STX-10 antigen, recognized by the monoclonal antibody HSA-10, was found to be present in human placenta and in human sperm. This antigen was isolated from placenta and sperm extracts by immunoaffinity chromatography, it was then analyzed by sodium dodecyl sulfate-polyacrylamide gel electrophoresis and by western blotting to be a 75±5 kD protein. By enzyme-linked immunosorbent assay, the isolated protein was found to react specifically with rabbit anti-STX- 10 serum and with HSA- 10 antibody. The immunoreactivity of the STX- 10 protein was quantitatively determined by sandwich enzyme immunosorbent assay, with HSA-10 as the capturing and detecting antibody. By indirect immunofluorescent assay, the STX-10 antigen in sperm was found to be localized to the inner acrosome of human sperm. Rabbit anti-STX-10 sera were used to screen a Xgtl 1 human placenta eDNA library. Following isolation and purification of positive cDNA clones, the cDNA inserts were analyzed by restriction enzyme digestions, and PCR amplifications. One clone, 1 kb in size, was obtained. The cDNA insert of the 1 kb clone was sequenced and found to be mainly composed of the 3’untranslated region, including an mR.NA degradation signal. In the 3’-untranslated region, an identical sequence was found to 411 bp of a 449 bp clone isolated from the male liver HepG2 carcinoma cell line. The 1 kb cDNA clone contained a possible open reading frame of 168 amino acids in size. The full length of the open reading frame for the STX-10 gene still remains to be elucidated. In Northern blots, the 1 kb cDNA fragment was used as the probe. The mRNA derived from human carcinoma BeWo cell line, known to express the STX-10 antigen, was found to be 5.5 kb in length. In conclusion, the STX- 10 antigen which is recognized by monoclonal antibody HSA- 10, is an unique antigen that should be strongly considered for the development of an immunocontraceptive vaccine.
On the Optimal Reconfiguration of Multipipeline Arrays in the Presence of Faulty Processing and Switching Elements

description: This paper deals with the reconfiguration of multipipelinearrays in the presence of both faulty processing elements (PE’s) and switching elements (SE’s). Different fault models are used for the PE’s and SE’s: a PE can he either fault free or faulty; a SE is modeled using a novel functional approach which relates its switching capabilities to its status. This permits a PE to retain a partial functionality in the presenceof a fault. An appropriate transformation of the multipipeline army reconfiguration problem to a maximum flow problem is then presented. The conditions under which this transformation is possible, are fully analyzed. A reconfiguration algorithm based on the Maximum FlowAlgorithm, is presented; the proposed algorithm is optimal as the number of reconfigured pipelines is maximized.

description: We study the realizability of simplicial complexes with a given pair of integer sequences, representing the node degree distribution and the facet size distribution, respectively. While the $s$-uniform variant of the problem is $\mathsf{NP}$-complete when $s \geq 3$, we identify two populations of input sequences, most of which can be solved in polynomial time using a recursive algorithm that we contribute. Combining with a sampler for the simplicial configuration model [J.-G. Young $\textit{et al.}$, Phys. Rev. E $\textbf{96}$, 032312 (2017)], we facilitate the efficient sampling of simplicial ensembles from arbitrary degree and size distributions. We find that, contrary to expectations based on dyadic networks, increasing the nodes' degrees reduces the number of loops in simplicial complexes. Our work unveils a fundamental constraint on the degree-size sequences and sheds light on further analysis of higher-order phenomena based on local structures.

In particular, we analyze the instanton moduli space using string theory methods and compute the prepotential of the effective gauge theory exploiting the localization methods of the instanton calculus showing that this leads to the same information given by the topological string. We also comment on the relation between our approach and the so-called Omega-background.

description: Radio interferometric (RI) data are noisy under-sampled spatial Fourier components of the unknown radio sky affected by direction-dependent antenna gains. Failure to model these antenna gains accurately results in a radio sky estimate with limited fidelity and resolution. The RI inverse problem has been recently addressed via a joint calibration and imaging approach which consists in solving a non-convex minimisation task, involving suitable priors for the DDEs, namely temporal and spatial smoothness, and sparsity for the unknown radio map via an $\ell_1$-norm prior, in the context of realistic RI simulations. Building on these developments, we propose to promote sparsity of the radio map via a log-sum prior, enforcing sparsity more strongly than the $\ell_1$-norm. The resulting minimisation task is addressed via a sequence of non-convex minimisation tasks composed of re-weighted $\ell_1$ image priors, which are solved approximately. We demonstrate the efficiency of the approach on RI observations of the celebrated radio galaxy Cygnus~A obtained with the Karl G. Jansky Very Large Array at X, C, and S bands. More precisely, we showcase that the approach enhances data fidelity significantly while achieving high resolution high dynamic range radio maps, confirming the suitability of the priors considered for the unknown DDEs and radio image. As a clear qualitative indication of the high fidelity achieved by the data and the proposed approach, we report the detection of three background sources in the vicinity of Cyg~A, at S band.

description: Electromagnetic observations have provided strong evidence for the existence of massive black holes in the center of galaxies, but their origin is still poorly known. Different scenarios for the formation and evolution of massive black holes lead to different predictions for their properties and merger rates. LISA observations of coalescing massive black hole binaries could be used to reverse engineer the problem and shed light on these mechanisms. In this paper, we introduce a pipeline based on hierarchical Bayesian inference to infer the mixing fraction between different theoretical models by comparing them to LISA observations of massive black hole mergers. By testing this pipeline against simulated LISA data, we show that it allows us to accurately infer the properties of the massive black hole population as long as our theoretical models provide a reliable description of the Universe. We also show that measurement errors, including both instrumental noise and weak lensing errors, have little impact on the inference.

description: Parallel processing systems with cache or localmemory in the memory hierarchies have become very common. These systems have local cache memory in each processor and usually employ write-invalidate protocol for the cache coherence. In such systems, a problem called “cache or local memory thrashing” may arise in executions of parallel programs, when the data unnecessarily moves back and forth between the caches or local memories in different processors. The techniques associated with parallelized compilers to solve the problem have not been completely developed.
In this paper we present an approach to eliminate, or at least to reduce, unnecessary data movement between the caches or local memories for nested parallel loops. This approach is based on relations between array element accesses and enclosed loop indexes in the nested parallel loops. The relations can be used to assign processors to execute the appropriate iterations for parallel loops in the loop nests with respect to the data in their caches or local memories. An algorithm to calculate the correct iteration of the parallel loop in terms of loop indexes of the previous iterations executed in the processor is presented in the paper, even though there is more than one subscript expression of the same array variable in the loop.
This method benefits parallel code with nested loop structures in a wide range of applications, in which the array elements are repeatedly referenced in the parallel loops. The experimental results show that the technique is extremely effective-capable of achieving speedups up to 2 over application programs such as Linpack benchmarks.

description: This is a preliminary examination of a body of coastal Tlingit oral narratives about first contact with Europeans collected and recorded by ethnologists between 1886 and 1984. In this paper, I compare how three features of the contact situation -- the Tlingit's initial perception of European ships, the nature of the first Tlingit-white interaction, and the Tlingit's reactions to European cultural products -- are portrayed in different versions of the accounts. I adopt the idea that one useful way to interpret these narratives is to understand them as a means by which the Tlingit interpret and order their past, and I argue that both the immobility of some features in the narratives, as well as the transformation of others, can perhaps best be understood if the chronicles are analyzed within the historical contexts in which they were told. Such an analysis reveals that a correlation may exist between the way contact with Europeans is depicted in the narratives and the historical events and social structures that were having significant impact upon the Tlingit's existence at the time of their telling. And I suggest in this study that this correlation demonstrates that the Tlingit, far from possessing ritualized, immobile, or mythic preconceptions of the past, possess active historical traditions that, like all historical traditions, are periodically revised and reinterpreted in the light of new information and insight.

description: Inelastic $α$ scattering on 16O is studied at 400 MeV by using an ice target. Near the 4-alpha breakup threshold of 14.4 MeV, a broad peak is observed at an excitation energy of 13.6+/-0.2 MeV with a width of 0.6+/-0.2 MeV. The spin-parity is estimated to be 0+ from the momentum-transfer dependence. The observed width is significantly larger than those of the neighboring 0+ states indicating a state with a well-developed alpha cluster structure. The magnitude of the cross section is sensitive to the density distribution of the constituent alpha clusters. The observed cross section is consistent with the theoretical prediction for the alpha cluster condensed state characterized by its dilute density distribution with a large root-mean-square radius of about 4.3 fm.

description: We perform a systematic analysis of standard model extensions with an additional anomaly-free gauge $U(1)$ symmetry, to generate Dirac neutrino masses at one loop. Under such symmetry, standard model fields could either transform or be invariant, corresponding to an active $U(1)_X$ or a dark $U(1)_D$ symmetry, respectively. Having an anomaly-free symmetry imposes nontrivial conditions to the number and charges of the unavoidable new states. We perform an intensive scan, looking for non-anomalous solutions for given number of extra chiral fermions. In particular, we concentrate on solutions giving rise to scotogenic neutrino masses via the effective Dirac mass operator. We study the cases where the Dirac mass operator with dimension 5 or 6, is mediated by Dirac or Majorana states, and corresponds to an active $U(1)_X$ or a dark $U(1)_D$ symmetry. Finally, we comment on the solutions featuring no massless chiral fermions.

description: Phosphaturic mesenchymal tumors (PMTs) are very rare neoplasms which are usually associated with Tumor Induced Osteomalacia (TIO). TIO is a paraneoplastic syndrome related to renal phosphate wasting, and causes general symptoms such as bone pain, multiple bone fractures, osteopenia, muscular weakness and usually is misdiagnosed. The purpose of the current paper is to present a case of phosphaturic mesenchymal tumor of the oral cavity in a female patient, that treated symptomatically, and after the surgical excision of the tumor, the symptoms disappeared dramatically. The systematic review summarizes the knowledge from the literature for these rare neoplasms.

description: In this talk I will begin with a very brief discussion as to why TeV scale Supersymmetry forms an important subject of the studies at all the current and future Colliders. Then, I will give different examples where the Photon Linear Collider, PLC, will be able to make unique contributions. PlC's most important role is in the context of Higgs Physics, due to its ability of accurate determination of $Γ_{γγ}$ as well as the possibilities it offers for the determination of the CP property of the Higgs boson and of possible CP mixing in the Higgs sector. Further, the PLC can provide probes of SUSY in the regions of the SUSY parameter space, which are either difficult or inaccessible at the LHC and also in the $e^+e^-$ mode of the International Linear Collider (ILC).
