description: We demonstrate experimentally a procedure to obtain the maximum efficiency for the storage and retrieval of light pulses in atomic media. The procedure uses time reversal to obtain optimal input signal pulse-shapes. Experimental results in warm Rb vapor are in good agreement with theoretical predictions and demonstrate a substantial improvement of efficiency. This optimization procedure is applicable to a wide range of systems.

description: We investigate unification constraints in the simplest renormalizable non-supersymmetric SU(5) framework. We show that in the scenario where the Higgs sector is composed of the 5, 24, and 45 dimensional representations the proton could be practically stable. We accordingly demonstrate that of all the SU(5) scenarios only the non-renormalizable one with the 5, 24, and 15 dimensional Higgs multiplets can be verify if low-energy supersymmetry is not realized in Nature.

description: A two-dimensional Pauli Hamiltonian describing the interaction of a neutral spin-1/2 particle with a magnetic field having axial and second order symmetries, is considered. After separation of variables, the one-dimensional matrix Hamiltonian is analyzed from the point of view of supersymmetric quantum mechanics. Attention is paid to the discrete symmetries of the Hamiltonian and also to the Hamiltonian hierarchies generated by intertwining operators. The spectrum is studied by means of the associated matrix shape-invariance. The relation between the intertwining operators and the second order symmetries is established and the full set of ladder operators that complete the dynamical algebra is constructed.

description: An analysis of steganographic systems subject to the following perfect undetectability condition is presented in this paper. Following embedding of the message into the covertext, the resulting stegotext is required to have exactly the same probability distribution as the covertext. Then no statistical test can reliably detect the presence of the hidden message. We refer to such steganographic schemes as perfectly secure. A few such schemes have been proposed in recent literature, but they have vanishing rate. We prove that communication performance can potentially be vastly improved; specifically, our basic setup assumes independently and identically distributed (i.i.d.) covertext, and we construct perfectly secure steganographic codes from public watermarking codes using binning methods and randomized permutations of the code. The permutation is a secret key shared between encoder and decoder. We derive (positive) capacity and random-coding exponents for perfectly-secure steganographic systems. The error exponents provide estimates of the code length required to achieve a target low error probability. We address the potential loss in communication performance due to the perfect-security requirement. This loss is the same as the loss obtained under a weaker order-1 steganographic requirement that would just require matching of first-order marginals of the covertext and stegotext distributions. Furthermore, no loss occurs if the covertext distribution is uniform and the distortion metric is cyclically symmetric; steganographic capacity is then achieved by randomized linear codes. Our framework may also be useful for developing computationally secure steganographic systems that have near-optimal communication performance.

description: Previous studies of quantum delta-kicked rotors have found momentum probability distributions with a typical width (localization length $L$) characterized by fractional $\hbar$-scaling, ie $L \sim \hbar^{2/3}$ in regimes and phase-space regions close to `golden-ratio' cantori. In contrast, in typical chaotic regimes, the scaling is integer, $L \sim \hbar^{-1}$. Here we consider a generic variant of the kicked rotor, the random-pair-kicked particle (RP-KP), obtained by randomizing the phases every second kick; it has no KAM mixed phase-space structures, like golden-ratio cantori, at all. Our unexpected finding is that, over comparable phase-space regions, it also has fractional scaling, but $L \sim \hbar^{-2/3}$. A semiclassical analysis indicates that the $\hbar^{2/3}$ scaling here is of quantum origin and is not a signature of classical cantori.

Conversion of subtilisin E to thiolsubtilisin by site-directed mutagenesis
Creators: name: Chen, Lu
Publisher: name: University of British Columbia
Year: 2009

description: This thesis presents a procedure of site specific mutagenesis of subtilisin E for reducing its proteolytic activity while retaining its ligase activity in peptide synthesis. A host-vector system was chosen to conduct the DNA manipulation and the gene expression. Subtilisin B gene (aprE) cloned on the plasmid DNA pAP65 was subcloned to a phagemid DNA pUC1 18 to facilitate KunkePs oligonucleotide directed mutagenesis. A new plasmid DNA pAP65D was developed from pAP65 and used to harbor subtilisin E gene and thiolsubtilisin gene. As a host cell, the B. subtilis DB428 strain, which is deficient in three major extracellular protease genes, was transformed with the plasmid DNA for expressing subtilisin E gene and thiolsubtilisin gene. By using this procedure, one of the catalytic active site residues on subtilisin E, serine 221, was replaced by a cysteine residue; thus a mutant product, thiolsubtilisin, was obtained. DNA sequencing confirmed both the subtilisin E gene on pAP65D8 and thiolsubtilisin gene on pAP65D8M. An improved transformation method with higher transformation efficiency was derived. The proteolytic activities of subtilisin E and thiolsubtilisin were compared. The B. subtilis transformants with pAP65D8 containing aprE and pAP65D8M containing thiolsubtilisin gene, developed halos around the colonies on skim milk agar plates. However, the halo produced by colonies with thiolsubtilisin gene was smaller than those with aprE. Subtiisin E and thiolsubtilisin secreted into the culture media were then subjected to a proteolytic activity assay. The proteolytic activity measurement, by using Succinyl-Ala-Ala-Pro-Phe-p-nitroanilide as a substrate, showed that the proteolytic activity of thiolsubtilisin was about 30% of that of subtiisin E, when culture supernatants were assayed. The ligase activity of subtilisin E and thiolsubtilisin was initially planned to be measured by using a solid phase detection method. However, the solid phase detection method failed in this case due to the fact that the enzymes react with the antibody used in the method. As a preliminary test, the ligase activities of subtilisin E and subtilisin Carlsberg were investigated. It was found that both enzymes can catalyze the formation of the dipeptide Z-L-Phe-Met-O-Me. HPLC was found to be able to detect such formation. Further study on the ligase activity of subtilisin B and thiolsubtilisin is suggested.
RWRMTN: a tool for predicting disease-associated microRNAs on a microRNA-target gene network

description: The misregulations of microRNA have been shown the contribution to diseases. Because identification of microRNAs for certain diseases in laboratories is time-consuming, numerous network-based methods have been developed to predict novel microRNAs. The homogeneous networks based on the shared targets among microRNAs have been widely used to predict their roles in certain diseases. Although the homogeneous networks can provide potential microRNAs, they do not consider the roles of the target genes. Recently, we have proposed a computational method based on a random walk framework on a microRNA-target gene network to predict disease-associated microRNAs (Le, et al., 2017). This was shown superior when compared to existing state-of-the-art network- and machine learning-based methods since it well exploits mutual regulation between microRNAs and their target genes in microRNA-target gene networks.
To facilitate the use of this method, we develop a Cytoscapeapp, named RWRMTN, to predict disease-associated microRNAs. RWRMTN can work on any microRNA-target gene network. Highly ranked microRNAs can be supported with evidence from the literature. Then, they can be also visualized based on the rankings in relationships with the query disease and their target genes. In addition, automation functions are also integrated, which permits RWRMTN can be used from external environments.

description: A neural network model of a differential equation, namely neural ODE, has enabled the learning of continuous-time dynamical systems and probabilistic distributions with high accuracy. The neural ODE uses the same network repeatedly during a numerical integration. The memory consumption of the backpropagation algorithm is proportional to the number of uses times the network size. This is true even if a checkpointing scheme divides the computation graph into sub-graphs. Otherwise, the adjoint method obtains a gradient by a numerical integration backward in time. Although this method consumes memory only for a single network use, it requires high computational cost to suppress numerical errors. This study proposes the symplectic adjoint method, which is an adjoint method solved by a symplectic integrator. The symplectic adjoint method obtains the exact gradient (up to rounding error) with memory proportional to the number of uses plus the network size. The experimental results demonstrate that the symplectic adjoint method consumes much less memory than the naive backpropagation algorithm and checkpointing schemes, performs faster than the adjoint method, and is more robust to rounding errors.

description: The boundary of the first order chiral phase transition region is studied in the m_pi-m_K-mu_B space using the one-loop optimized perturbation theory for the resummation of the perturbative series. Chiral perturbation theory for mesons and baryons is used for the T=0 parametrization of the model. The surface of second order transition points bends with increasing mu_B towards the physical point of the m_pi-m_K mass plane allowing for the existence of the critical end point in the mu_B-T plane at the physical point. The location and scaling region of the CEP is explored.

description: This note is concerned with potentially misleading concepts in the treatment of cosmological magnetic fields by magnetohydrodynamical (MHD) modelling. It is not a criticism of MHD itself but rather a cautionary comment on the validity of its use in cosmology. Now that cosmological data are greatly improved compared with a few decades ago, and even better data are imminent, it makes sense to revisit original modelling assumptions and examine critically their shortcomings in respect of modern science. Specifically this article argues that ideal MHD is a poor approximation around recombination, since it inherently restricts evolutionary timescales, and is often misapplied in the existing literature.

Effects of oxidized low density lipoprotein on endothelin secretion by cultured endothelial cells, monocytes and macrophages
Creators: name: He, Yi
Publisher: name: University of British Columbia
Year: 2009

description: Oxidized LDL is present in atherosclerotic lesions and has been shown to have a number of actions of potential importance in atherosclerosis, including stimulation of arterial vasoconstriction. The aim of this study was to determine how oxidized LDL affects endothelin secretion by endothelial cells, monocytes and macrophages. It was found that the effects of oxidized LDL on endothelin production depend on the degree of oxidation of LDL. Extensively oxidized LDL inhibited endothelin expression and secretion from cultured endothelial cells. It also attenuated endothelin release from phorbol ester-activated macrophages. The inhibitory effect on endothelin release required a threshold degree of LDL oxidation as reflected by an increase in absorbance at 234 nm (conjugated diene) of 0.1 per ug LDL protein and a 2 to 3-fold increase in migration distance on agarose gel electrophoresis. There was an apparent toxic effect of extensively oxidized LDL to the cells as judged by inhibition of protein and DNA synthesis. Thus, cytotoxicity of extensively oxidized LDL may at least in part account for the inhibition of endothelin secretion. Native LDL, mildly oxidized LDL or acetyl LDL slightly increased basal endothelin release by endothelial cells and by phorbol ester-activated peripheral blood monocytes. However, only mildly oxidized LDL modestly augmented endothelin production by phorbol ester-activated monocyte-derived macrophages. In general, the stimulatory effects of mildly oxidized LDL on endothelin secretion by cultured cells were of modest degree and/or not specific for mildly oxidized LDL (in that they were also seen with native LDL). For that reason, it is difficult to invoke this effect of mildly oxidized LDL as an important pathophysiological mechanism in vivo. Furthermore, the inhibition of endothelin secretion by extensively oxidized LDL might even be a protective mechanism, in that it would tend to reduce vessel wall tone at sites where oxidized LDL was present, i.e. near atherosclerotic lesions.

description: We demonstrate a strong coherent backward wave oscillation using forward propagating fields only. This is achieved by applying laser fields to an ultra-dispersive medium with proper chosen detunings to excite a molecular vibrational coherence that corresponds to a backward propagating wave. The physics then has much in common with propagation of ultra-slow light. Applications to coherent scattering and remote sensing are discussed.

description: This study comparatively evaluated and analyzed the use of music as a tool for engineering audiences on Love 97.7 FM, Cool 96.5 FM, and Wazobia 94.1 FM. The objectives were to determine the genres of music played by Love97.7 FM, Cool 96.5 FM, and Wazobia94.1 FM to engineer the audience. In addition, the study sought to determine whether Love 97.7FM, Cool 96.5FM, and Wazobia 94.1FM had deliberate policies on engineering audiences toward their radio stations through music. The theoretical underpinning of the study was anchored on active audience theory and uses and gratification theory. The design used in the study was a focus group discussion, and the researcher were the instrument for data collection. The sampling was done in two groups, with one focusing on selected staff members from the three different radio stations while the other focused on residents of the Port Harcourt metropolis, out of which a sample size of 15 was chosen with the purposive sampling technique. The three radio stations that were evaluated had audience engineering programs through music, such as the Drivetime Show on Cool 96.5 FM, the One Nigeria Radio show on Love97.7 FM, and the Lunch hour drive on Wazobia 94.1 FM. From the findings of the study, it was discovered that the genres of music, differently put, had played to engineer audiences toward their radio stations. In addition, Love 97.7 FM, Cool 96.5 FM, and Wazobia 94.1 FM had certain financial, musical, and governmental policies attached to their airplay to draw the audience through to their radio stations. In conclusion, from this research, recommendations are that these three radio stations should choose the appropriate genres of music that will facilitate audience engineering on their different radio platforms. Also, Love 97.7 FM, Cool 96.5 FM, and Wazobia 94.1FM FM should learn to take deliberate policies that will help them in audience engineering, especially by reviewing the music played by their stations regularly. Furthermore, Love97.7 FM, Cool 96.5 FM, and Wazobia 94.1 FM should learn to play the right music in order not to cause a nuisance or be seen as generating noise, which eventually leads to the audience switching over to another radio station frequency

description: Near-infrared imaging surveys of high-mass star-forming regions reveal an amazingly complex interplay between star formation and the environment (Churchwell et al. 2006; Alvarez et al. 2004). By means of near-IR spectroscopy the embedded massive young stars can be characterized and placed in the context of their birth site. However, so far spectroscopic surveys have been hopelessly incomplete, hampering any systematic study of these very young massive stars. New integral field instrumentation available at ESO has opened the possibility to take a huge step forward by obtaining a full spectral inventory of the youngest massive stellar populations in star-forming regions currently accessible. Simultaneously, the analysis of the extended emission allows the characterization of the environmental conditions. The Formation and Early Evolution of Massive Stars (FEMS) collaboration aims at setting up a large observing campaign to obtain a full census of the stellar content, ionized material, outflows and PDR's over a sample of regions that covers a large parameter space. Complementary radio, mm and infrared observations will be used for the characterization of the deeply embedded population. For the first eight regions we have obtained 40 hours of SINFONI observations. In this contribution, we present the first results on three regions that illustrate the potential of this strategy.

description: We discuss the properties of the hadron-quark mixed phase in compact stars using a realistic equation of state of hyperonic matter and the MIT bag model. We find that the equation of state of the mixed phase is similar to that given by the Maxwell construction, but that the mixed phase becomes mechanically unstable if the surface tension of the interface between the two pure phases is strong enough. The composition of the mixed phase is very different from that of the Maxwell construction; in particular, hyperons are completely suppressed.

description: Knowledge of transcription factor (TF)-binding sites, the locations at which TFs bind to DNA in the genome, is key to understanding how genes are regulated. Yet, the binding preferences of most eukaryotic TFs remain unknown. In this scenario, the development of computational tools as a complement to experimental procedures is fundamental. Here, we introduce ModCRE, a homology modeling-based approach that combines structural information and protein binding microarray (PBM) data to predict the binding preferences of TFs and model TF-DNA interactions. ModCRE was applied to the following tasks: 1) discriminate bound from unbound PBM 8-mers; 2) predict JASPAR profiles from experimental methods excluding PBMs; 3) predict profiles of non-redundant TFs and compare them to the profiles of the closest non-redundant homologs; and 4) model the structure of the INFβ human enhanceosome. Thanks to its automated homology modeling pipeline for TF-DNA interactions, ModCRE could be applied large-scale to fill the existing gaps in gene regulatory networks.

Έχουν γίνει τεράστιες προσπάθειες από τη διεθνή ερευνητική κοινότητα να μελετηθούν και να αντιμετωπιστούν αυτές οι μεροληψίες αλλά κάποιες είναι σχεδόν αδύνατο να αντιμετωπιστούν, διότι μία από τις βασικότερες ιδιότητες τέτοιων μεροληψιών είναι η δυσκολία στο να τις ορίσουμε και άρα να τις αντιμετωπίσουμε. Κάποιες όμως μεροληψίες είναι πιό εύκολο να τις διαχειριστούμε και στην παρούσα μελέτη αυτό κανουμε. Η μεροληψία η οποία περιγράφεται και προσεγγίζεται στην εργασία αυτή έχει σχέση τόσο στις δειγματοληπτικές έρευνες γενικότερα όσο και στις δημοσκοπήσεις στο διαδίκτυο. Επίσης, περιγράφονται και άλλα σφάλματα που προκύπτουν από τις έρευνες αυτές.
description: ABSTRACT The world wide web in not only an entertainment and information mean, but it consists a new mean of data collection for the surveys. It can be used either as a key tool for conducting the research or as adjuvant. With proper selection of population and sampling frame the web surveys could be useful. Nevertheless the risk of errors and misinformation persists. These errors could be sampling or nonsampling errors. Sampling errors have the property, which is good for the researcher, to decrease and to deteriorate as the sample increases. Nonsampling errors does not have this property, and in any case it is more difficult to use them and they are more connected with the meaning of bias. There have been enormous efforts by the international research community to study and address these biases, but some are impossible to address because one of the main properties of such biases is the difficulty to define and thus to deal with. But some biases are easier to manage and that what we do in the present study. The bias, that we are concerning and approaching in this study, is related to both general surveys and web surveys. Also, we are describing and other errors resulting from these investigations.

description: Stirring of fluid with moving rods is necessary in many practical applications to achieve homogeneity. These rods are topological obstacles that force stretching of fluid elements. The resulting stretching and folding is commonly observed as filaments and striations, and is a precursor to mixing. In a space-time diagram, the trajectories of the rods form a braid, and the properties of this braid impose a minimal complexity in the flow. We review the topological viewpoint of fluid mixing, and discuss how braids can be used to diagnose mixing and construct efficient mixing devices. We introduce a new, realisable design for a mixing device, the silver mixer, based on these principles.

description: The presentation introduces to the current best picture we have of the history and constituents of our universe. It describes the so called Lambda-Cold-Dark-Matter cosmological model, which is supported most by evidence. An overview is given of some of the early ground-based observations as well as the space missions by ESA and NASA, which provided the evidence that speaks for this model. Finally, it is described how this model is submitted to more and more stringent tests using space telescopes like Euclid and Nancy Grace Roman.

description: The feasibility of observing the C18O (3-2) spectral line in cold clouds with the APEX telescope has been tested. As the line at 329.330 GHz lies in the wing of a strong atmospheric H2O absorption it can be observed only at high altitude observatories. Using the three lowest rotational levels instead of only two helps to narrow down the physical properties of dark clouds and globules. The centres of two C18O maxima in the high latitude low mass star forming region CG 12 were mapped in C18O (3-2) and the data were analyzed together with spectral line data from the SEST. The T_MB(3-2)/T_MB(2-1) ratio in the northern C18O maximum, CG 12 N, is 0.8, and in the southern maximum, CG 12 S, ~2. CG 12 N is modelled as a 120'' diameter (0.4pc) cold core with a mass of 27 Msun. A small size maximum with a narrow, 0.8 kms-1, C18O (3-2) spectral line with a peak temperature of T_MB ~11 K was detected in CG 12 S. This maximum is modelled as a 60'' to 80'' diameter (~0.2pc) hot (80 K < Tex < 200 K) ~1.6 Msun clump. The source lies on the axis of a highly collimated bipolar molecular outflow near its driving source. This is the first detection of such a compact, warm object in a low mass star forming region.

description: We study the lowest dimensional open case of the question whether every arithmetically Cohen--Macaulay subscheme of $\mathbb{P}^N$ is glicci, that is, whether every zero-scheme in $\mathbb{P}^3$ is glicci. We show that a set of $n \geq 56$ points in general position in $\PP^3$ admits no strictly descending Gorenstein liaison or biliaison. In order to prove this theorem, we establish a number of important results about arithmetically Gorenstein zero-schemes in $\mathbb{P}^3$.

description: Previous numerical investigations of the stability and bifurcation properties of different nonlinear combination structures of spiral vortices in a counterrotating Taylor-Couette system that were done for fixed axial wavelengths are supplemented by exploring the dependence of the vortex phenomena waves on their wavelength. This yields information about the experimental and numerical accessability of the various bifurcation scenarios. Also backwards bifurcating standing waves with oscillating amplitudes of the constituent traveling waves are found.

Effect of fiscal policy on housing finance in India
Creators: name: Krishan, Deepa
Publisher: name: University of British Columbia
Year: 2009

description: This thesis attempts to identify elements needed in a fiscal policy designed to encourage private investment towards urban housing in India. The need for such a policy arises due to the existing and projected urban housing shortage in India. The Government of India attempts to address housing shortages through subsidies, tax incentives and regulation. However, the urban housing shortage continues to increase. One of the major constraints identified is the shortage of housing finance. An estimated investment of Rs. 572 billion is required to meet the existing urban housing shortage of about 10 million units. Fiscal policy instruments are useful in directing finance towards selected priority sectors. This thesis suggests that the fiscal policies of India be designed to encourage private investment in the urban housing sector. Only a limited number of studies have been made to ascertain how fiscal policies influence housing and housing finance, even though tax incentives that affect housing are commonly used in many countries. These studies show that the effect of most housing tax expenditures is regressive. The incentives given by housing tax expenditures directly affect only the tax payers, and thus would be limited to the top two quintiles of Indian population. People in lower income groups would not benefit and would be discriminated against by these policies. For increasing urban housing in India, there is need to suggest policy measures that favourably impact all sections of the population. A fiscal policy that helps the financial institutions to mobilize household savings towards investment in urban housing is necessary. These policies can be designed to encourage the rich to invest in institutions that provide low-cost housing finance credit to the poorer sections. This will enable the urban dwellers, including the poorer sections amongst them, to have access to finance for housing at reasonable interest rates. The fiscal policy must also give incentives to employers to provide housing or housing finance to their employees. They should also encourage businesses to invest in housing for low-income groups, and developers to provide subsidized housing to them. Such incentives would also help in reducing the role of the underground economy in the housing sector. Policies that actively discourage hoarding and speculation in land and property, such as a tax on vacant land, would increase the supply of housing. In India, such fiscal policies would need to be complemented by changes in the regulatory framework to remove the deleterious effects of other policies, such as rent control laws, on the supply of housing. A tax system incorporating incentives to promote housing, formulated in coordination with housing and urban planners, and with a provision for regular evaluation of its effectiveness is likely to considerably help reduce the shortage of housing finance.

The records of lawyers : archival appraisal and access
Creators: name: Gourlie, Michael
Publisher: name: University of British Columbia
Year: 2009

description: Despite the importance of lawyers as persons within the legal system, their activities have not been well-represented in the documentary heritage of society as preserved in archives. The primary reason behind this situation is the principle of solicitor-client privilege, which traditionally protects the lawyer-client relationship from disclosure. The privilege has not only barred the archival acquisition of and access to client files for research purposes but has also apparently prevented any in depth study of the records lawyers create. This study attempts to shed light on the records created by lawyers and their possible disposition. First, the thesis uses the concepts of diplomatics and an analysis of the historical development of lawyers to categorize their work. The functions it defines include maintaining a legal practice, contributing to the profession and providing legal services to clients. The thesis then examines the central function of providing legal services by analyzing an actual lawyer’s fonds and comparing it with related records in court registries. This analysis illustrates how lawyers records fall both into functional categories and diplomatic phases. It also reveals that, contrary to certain observers, few of the documents in the lawyer’s file appear in the court registries and even fewer are preserved in archives as a result of records management decisions by the registries. These findings provide grounds to consider archival appraisal of lawyers’ records. First, it is argued that concerns about solicitor-client privilege need not inhibit preservation and access to lawyers’ records in archival institutions. With this impediment removed, archivists can proceed to acquire the fonds of lawyers on a selective basis both among and within fonds. In terms of appraisal for selection, certain records resulting from the activities within the functions of maintaining a legal practice and contributing to the profession are worthy of permanent preservation and have no access restrictions on their use. For the function of providing legal services, a statistically-valid sample of these case files should be preserved to illustrate this aspect of a lawyer’s work. However, it is vital that lawyers and archivists must work together on finding mutually acceptable policies that both respect the privacy of clients and allow access to the record of legal practice for future generations.

description: We present the measurement of R = B(t->Wb)/B(t->Wq) in ppbar collisions at sqrt(s) = 1.96 TeV, using 230 pb-1 of data collected by the DO experiment at the Fermilab Tevatron Collider. We fit simultaneously R and the number of selected top quark pairs (ttbar), to the number of identified b-quark jets in events with one electron or one muon, three or more jets, and high transverse energy imbalance. To improve sensitivity, kinematical properties of events with no identified b-quark jets are included in the fit. We measure R = 1.03 +0.19 -0.17 (stat+syst), in good agreement with the standard model. We set lower limits of R > 0.61 and |V_tb| > 0.78 at 95% confidence level.

description: In this paper it will be shown that the Standard Model in 3+1 dimensions is a gauge fixed version of a 2T-physics field theory in 4+2 dimensions, thus establishing that 2T-physics provides a correct description of Nature from the point of view of 4+2 dimensions. The 2T formulation leads to phenomenological consequences of considerable significance. In particular, the higher structure in 4+2 dimensions prevents the problematic F*F term in QCD. This resolves the strong CP problem without a need for the Peccei-Quinn symmetry or the corresponding elusive axion. Mass generation with the Higgs mechanism is less straightforward in the new formulation of the Standard Model, but its resolution leads to an appealing deeper physical basis for mass, coupled with phenomena that could be measurable. In addition, there are some brand new mechanisms of mass generation related to the higher dimensions that deserve further study. The technical progress is based on the construction of a new field theoretic version of 2T-physics including interactions in an action formalism in d+2 dimensions. The action is invariant under a new type of gauge symmetry which we call 2Tgauge-symmetry in field theory. This opens the way for investigations of the Standard Model directly in 4+2 dimensions, or from the point of view of various embeddings of 3+1 dimensions, by using the duality, holography, symmetry and unifying features of 2T-physics.
