description: We propose a quantum Monte Carlo approach to solve the ground state many-body Schrodinger equation for the electronic ground state. The method combines optimization from variational Monte Carlo and propagation from auxiliary field quantum Monte Carlo, in a way that significantly alleviates the sign problem. In application to molecular systems, we obtain highly accurate results for configurations dominated by either dynamic or static electronic correlation.

We discuss stationary states of dissipative quantum systems, which coincide with stationary states of Hamiltonian quantum systems. Dissipative quantum systems with pure stationary states of linear harmonic oscillator are suggested.

description: The realization of complex classification tasks requires training of deep learning (DL) architectures consisting of tens or even hundreds of convolutional and fully connected hidden layers, which is far from the reality of the human brain. According to the DL rationale, the first convolutional layer reveals localized patterns in the input and large-scale patterns in the following layers, until it reliably characterizes a class of inputs. Here, we demonstrate that with a fixed ratio between the depths of the first and second convolutional layers, the error rates of the generalized shallow LeNet architecture, consisting of only five layers, decay as a power law with the number of filters in the first convolutional layer. The extrapolation of this power law indicates that the generalized LeNet can achieve small error rates that were previously obtained for the CIFAR-10 database using DL architectures. A power law with a similar exponent also characterizes the generalized VGG-16 architecture. However, this results in a significantly increased number of operations required to achieve a given error rate with respect to LeNet. This power law phenomenon governs various generalized LeNet and VGG-16 architectures, hinting at its universal behavior and suggesting a quantitative hierarchical time-space complexity among machine learning architectures. Additionally, the conservation law along the convolutional layers, which is the square-root of their size times their depth, is found to asymptotically minimize error rates. The efficient shallow learning that is demonstrated in this study calls for further quantitative examination using various databases and architectures and its accelerated implementation using future dedicated hardware developments.

description: Measurements of the Casimir force are used to obtain stronger constraints on the parameters of hypothetical interactions predicted in different unification schemes beyond the Standard Model. We review new strong constraints on the Yukawa-type interactions derived during the last two years from recent experiments on measuring the lateral Casimir force, Casimir force in configurations with corrugated boundaries and the Casimir-Polder force. Specifically, from measurements of the lateral Casimir force compared with the exact theory the strengthening of constraints up to a factor of 24 millions was achieved. We also discuss further possibilities to strengthen constraints on the Yukawa interactions from the Casimir effect.

description: Samaras are tree seeds that spontaneously rotate about the vertical axis as they fall. This flight pattern, referred to as autorotation, generates aerodynamic lift to slow a samara’s descent. In this thesis, samara flight is studied in steady-state and during a transient gust-response. In steady-state autorotation, the circulation and topology of the flow over samaras are investigated using particle image velocimetry (PIV). The stable attachment of leading-edge vortices - a lift-enhancing mechanism - is shown to depend on tip speed ratio. Leading-edge circulation, however, is insensitive to changes in tip speed ratio. The dynamic gust-response of samaras is studied using high-speed video. A linear dynamic model is developed based on momentum theory, and is shown to adequately predict the post-gust acceleration of an Acer negundo samara. The model predicts that axial gusts of sufficient strength or frequency can disrupt autorotation by compromising pitch-stability.
25-Hydroxycholesterol Regulates Inflammation by Activating Integrin-FAK Signaling Pathway

Subjects: Inflammation

description: Inflammation is part of host innate immune response constituting the first line of defense against invading pathogens. Regulated inflammation is required for tissue homeostasis and host defense however, dysregulated inflammation is detrimental as it leads to tissue damage and development of various inflammatory diseases like arthritis, diabetes, Alzheimer’s etc. The cells of innate immune system like macrophages play a pivotal role during inflammation. Various receptors like Pathogen Recognition Receptors (PRRs) and Tumor Necrosis Factor-α receptor (TNFR) play important roles in triggering inflammatory response during infectious and non-infectious diseases. The activation of PRRs and TNFR results in the activation of various downstream signaling cascade which includes NFB, MAPK (mitogen activated protein kinase) and type I interferon pathways. Specifically, activation of NFB ad MAPK pathways results in the trans-activation of pro-inflammatory genes and subsequent production of pro-inflammatory cytokines and chemokines that shapes the innate immune inflammatory response. Our study has identified a lipid oxysterol 25 hydroxycholesterol (25HC) as a key positive regulator of PRR and TNFR mediated inflammatory response. 25HC is generated from the enzymatic conversion of cholesterol to 25HC by cholesterol 25-hydroxylase (C25H). Here, in we report that expression of C25H and extracellular production of 25HC from a cytosolic PRR nucleotide oligomerization domain protein 2 (Nod2) activated cells, TNFR activated cells and virus (Respiratory syncytial virus and influenza virus) infected macrophages. During these events, extracellular 25HC binds to cell surface integrin to activate integrin- FAK (focal adhesion kinase)-NFB signaling pathway for optimal pro-inflammatory response. Furthermore, our study also reveals that C25H expression in TNFR activated cells require NFB and MAPK pathways. Thus, our study has identified MAPK/NFB-C25H-25HC-integrin-FAK-NFB signaling network as a novel cellular mechanism involved in amplification of the pro-inflammatory response following Nod2 (PRR) and TNFR activation. Furthermore, we showed that a lipid oxysterol like 25HC can act as a “bridge” to link PRR and TNFR pathways with integrin-FAK signaling for optimal pro-inflammatory response.

Probing Gas Motions in the Intra-Cluster Medium: A Mixture Model Approach

description: Upcoming high spectral resolution telescopes, particularly Astro-H, are expected to finally deliver firm quantitative constraints on turbulence in the intra-cluster medium (ICM). We develop a new spectral analysis technique which exploits not just the line width but the entire line shape, and show how the excellent spectral resolution of Astro-H can overcome its relatively poor spatial resolution in making detailed infer- ences about the velocity field. The spectrum is decomposed into distinct components, which can be quantitatively analyzed using Gaussian mixture models. For instance, bulk flows and sloshing produce components with offset means, while partial volume- filling turbulence from AGN or galaxy stirring leads to components with different widths. The offset between components allows us to measure gas bulk motions and separate them from small-scale turbulence, while component fractions and widths con- strain the emission weighted volume and turbulent energy density in each component. We apply mixture modeling to a series of analytic toy models as well as numerical simu- lations of clusters with cold fronts and AGN feedback respectively. From Markov Chain Monte Carlo and Fisher matrix estimates which include line blending and continuum contamination, we show that the mixture parameters can be accurately constrained with Astro-H spectra: at a \sim 10% level when components differ significantly in width, and a \sim 1% level when they differ significantly in mean value. We also study error scalings and use information criteria to determine when a mixture model is preferred. Mixture modeling of spectra is a powerful technique which is potentially applicable to other astrophysical scenarios.

description: This dissertation analyzed the tonal and acoustic properties of utterances produced from five native Thai speakers. The computational model produced classifications based on predictions made by a Hidden Markov Model that simulates tone perception and categorization. The computational model tested the categorization of stimuli taken from both citation and continuous contexts of Thai tonal data, in order to compare the performance of the computational model on both clear and naturalistic stimuli. Two perception experiments were also conducted, involving human listeners, for the purpose of comparing their behavior to that of the computational model. The results reveal that the classifications of lexical tone categories made by the computational model yield some dissimilar learning patterns to that found in human perceptual learning of the same categories.

description: We have performed 323 MHz observations with the Giant Metrewave Radio Telescope of the most promising candidates selected from the MACS catalog. The aim of the work is to extend our knowledge of the radio halo and relic populations to z>0.3, the epoch in which massive clusters formed. In MACSJ1149.5+2223 and MACSJ1752.1+4440, we discovered two double-relic systems with a radio halo, and in MACSJ0553.4-3342 we found a radio halo. Archival Very Large Array observations and Westerbork Synthesis Radio Telescope observations have been used to study the polarization and spectral index properties. The radio halo in MACSJ1149.5+2223 has the steepest spectrum ever found so far in these objects (alpha > 2). The double relics in MACSJ1149.5+2223 are peculiar in their position that is misaligned with the main merger axis. The relics are polarized up to 30% and 40% in MACSJ1149.5+2223 and MACSJ1752.040+44, respectively. In both cases, the magnetic field is roughly aligned with the relics' main axes. The spectra in the relics in MACSJ1752.040+44 steepen towards the cluster centre, in agreement with model expectations. X-ray data on MACSJ0553.4-3342 suggests that this cluster is undergoing a major merger, with the merger axis close to the plane of the sky. The cores of the disrupted clusters have just passed each other, but no radio relic is detected in this system. If turbulence is responsible for the radio emission, we argue that it must develop before the core passage. A comparison of double relic plus halo system with cosmological simulations allows a simultaneous estimate of the acceleration efficiencies at shocks (to produce relics) and of turbulence (to produce the halo).

description: We report a measurement of the strange axial coupling constant $g_A^s$ using atmospheric neutrino data at KamLAND. This constant is a component of the axial form factor of the neutral-current quasielastic (NCQE) interaction. The value of $g_A^s$ significantly changes the ratio of proton and neutron NCQE cross sections. KamLAND is suitable for measuring NCQE interactions as it can detect nucleon recoils with low-energy thresholds and measure neutron multiplicity with high efficiency. KamLAND data, including the information on neutron multiplicity associated with the NCQE interactions, makes it possible to measure $g_A^s$ with a suppressed dependence on the axial mass $M_A$, which has not yet been determined. For a comprehensive prediction of the neutron emission associated with neutrino interactions, we establish a simulation of particle emission via nuclear deexcitation of $^{12}$C, a process not considered in existing neutrino Monte Carlo event generators. Energy spectrum fitting for each neutron multiplicity gives $g_A^s =-0.14^{+0.25}_{-0.26}$, which is the most stringent limit obtained using NCQE interactions without $M_A$ constraints. The two-body current contribution considered in this analysis relies on a theoretically effective model and electron scattering experiments and requires future verification by direct measurements and future model improvement.
Sources and processes affecting atmospheric sulfur at the onset of Arctic winter

description: Arctic size segregated aerosols and SO2 concentrations were measured at two sites at the onset of winter in 2007 and 2008. Concentrations of non sea salt sulfate are within the same range as previous studies in the Arctic. Apportionment with tracer ions and isotopes were used to distinguish between biogenic sulfur and sulfur from other sources including sea salt, anthropogenic and two local Arctic sources; the Smoking Hills and frost flowers. A method to quantitatively differentiate between frost flower and sea salt sulfate using isotope analysis and constrained frost flower ratios is introduced. This is the first time contributions from frost flower in aerosols are reported quantitatively and reached a maximum of 2.3 nmol/m³. Fine aerosol anthropogenic sulfate concentrations were similar between the sites (Alert 0.8 ± 0.6 nmol/m³; Amundsen 0.3 ± 0.4 nmol/m³) and increased with the onset of winter. Ammonium, nitrate and non sea salt potassium correlated with anthropogenic sulfate at both locations. A strong relationship between anthropogenic sulfate and a deficit in aerosol chloride at Alert, Nunavut supports acidification of aerosols from long range transport in the Arctic fall. The first simultaneous measurements of dimethylsulfide (DMS), biogenic SO2, aerosol methanesulfonic acid (MSA) and biogenic sulfate in the Arctic were carried out. Median biogenic SO2 concentration was 0.07 nmol/m³. MSA concentrations decreased with the onset of winter. A median lifetime of 6.1 days for DMS during the sampling period was modeled. Measured MSA branching ratios (median values at Alert = 0.24; Amundsen = 0.28) were compared to ratios predicted by a DMS oxidation model and were found to be similar when modeled halogen and aqueous oxidation was low. DMS oxidation by NO3∙ is expected to be the largest contribution to DMS oxidation in the Arctic fall. A DMS transport model predicts the region around the Amundsen during the campaign was a net source of DMS (median net transport out of the region =10 nmol m-3 day-1) although the area at times acted as a sink. A net source of DMS from Arctic waters supports that sulfur chemistry in the Arctic is representative of regional and not local conditions.

description: Recently Kauers, Koutschan and Spahn announced a significant increase in the length of the so-called {\em gerrymander sequence}, given as A348456 in the OEIS, extending the sequence from 3 terms to 7 terms. We give a further extension to 11 terms, but more significantly prove that the coefficients grow as $λ^{4L^2},$ where $λ\approx 1.7445498, $ and is equal to the corresponding quantity for self-avoiding walks crossing a square (WCAS), or self-avoiding polygons crossing a square (PCAS). These are, respectively, OEIS sequences A007764 and A333323. Thus we have established a close connection between these previously separate problems. We have also related the sub-dominant behaviour to that of WCAS and PCAS, allowing us to conjecture that the coefficients of the gerrymander sequence A348456 grow as $λ^{4L^2+dL+e} \cdot L^g,$ where $d=-8.08708 \pm 0.0002,$ $e \approx 7.69$ and $g = 0.75 \pm 0.01,$ with $g$ almost certainly $3/4$ exactly. We also have generated 26 terms in the related gerrymander polynomial (defined below), and have been able to predict the asymptotic behaviour with a satisfying degree of precision. Indeed, it behaves exactly as $L$ times the corresponding coefficient of the generalised gerrymander sequence. The improved algorithm we give for counting these sequences is a variation of that which we recently developed for extending a number of sequences for SAWs and SAPs crossing a domain of the square or hexagonal lattices. It makes use of a minimal perfect hash function and in-place memory updating of the arrays for the counts of the number of paths.

description: A Brillouin-Wigner perturbation theory is developed for open electromagnetic systems which are characterised by discrete resonant states with complex eigenenergies. Since these states are exponentially growing at large distances, a modified normalisation is introduced that allows a simple spectral representation of the Green's function. The perturbed modes are found by solving a linear eigenvalue problem in matrix form. The method is illustrated on exactly solvable one- and three-dimensional examples being, respectively, a dielectric slab and a microsphere.

description: Reducing antibiotic usage in livestock animals has become an urgent issue worldwide to prevent antimicrobial resistance. Here, abuse of chlortetracycline (CTC), a versatile antibacterial agent, on the performance, blood components, fecal microbiota, and organic acid concentration in calves was investigated. Japanese Black calves were fed milk replacer containing CTC at 10 g/kg (CON) or 0 g/kg (EXP). Growth performance was not affected by CTC administration. However, CTC administration altered the correlation between fecal organic acids and bacterial genera. Machine learning methods such as association analysis, linear discriminant analysis, and energy landscape analysis revealed that CTC administration affected according to certain rules the population of various types of fecal bacteria. It is particularly interesting that the population of several methane-producing bacteria was high in the CON, and that of Lachnospiraceae, a butyrate-producing bacteria, was high in the EXP at 60 d of age. Furthermore, statistical causal inference based on machine learning data estimated that CTC treatment affects the entire intestinal environment, inhibiting butyrate production for growth and biological defense, which may be attributed to methanogens in feces. Thus, these observations highlight the multiple harmful impacts of antibiotics on intestinal health and the potential production of greenhouse gas in the calves.

description: Despite the enormous interest in the properties of graphene and the potential of graphene nanostructures in electronic applications, the study of quantum confined states in atomically well-defined graphene nanostructures remains an experimental challenge. Here, we study graphene quantum dots (GQDs) with well-defined edges in the zigzag direction, grown by chemical vapor deposition (CVD) on an iridium(111) substrate, by low-temperature scanning tunneling microscopy (STM) and spectroscopy (STS). We measure the atomic structure and local density of states (LDOS) of individual GQDs as a function of their size and shape in the range from a couple of nanometers up to ca. 20 nm. The results can be quantitatively modeled by a relativistic wave equation and atomistic tight-binding calculations. The observed states are analogous to the solutions of the text book "particle-in-a-box" problem applied to relativistic massless fermions.

description: The principal premise of this thesis is that the ambiguities of reservoir simulation can be and should be reduced by using time-lapse seismic data. Such data can be considered as a sort of reservoir dynamic data, with distinctive features compared to the typical reservoir production data. While well production data are sparse in space and dense in time, 4D time-lapse seismic can be utilized to fill the spatial data gaps between wells. This provides an opportunity to constrain reservoir dynamic behaviour not only at well locations but also between them by honoring time lapse response of the reservoir. This means that seismic assisted history matching should involve a simultaneous minimization of the mismatch between all types of measured and simulated data including seismic data. This thesis is an effort to discuss critical aspects of integrating 4D time-lapse data in reservoir simulation and history matching. I have illustrated a detailed scheme of seismic assisted history matching with implications on real data, to emphasize the extra value that seismic data can bring into the conventional reservoir history matching. This goal was followed by developing a software application to assess the feasibility of the theory at industrial scales. In addition to the conventional oils, a significant effort has been devoted to extend the scope of the work to viscoelastic heavy oils and their fluid substitution models in thermal cases. I also studied the production/injection induced stresses impacts on anisotropic velocity variations, using coupled geomechanical-flow simulations. The delineated scheme in seismic assisted history matching, proved to have a crucial contribution that cannot be ignored. The dynamic model for reservoir simulation should always be kept as simple as possible, but not simpler! This thesis is an argument that ignoring time lapse seismic data, builds a model which is simpler than a trustworthy model.

description: Remote temperature control can be obtained by a long-focus thermal lens that can focus heat fluxes into a spot far away from the back surface of the lens and create a virtual thermal source/sink in the background material, around which the temperature field distribution can be remotely controlled by changing the parameters of the thermal lens. However, due to the lack of negative thermal conductivity, the existing thermal lenses have extremely short focal lengths and cannot be used to remotely control the temperature field around the virtual thermal source/sink. In this study, we theoretically propose a general approach to equivalently realize negative thermal conductivity by elaborately distributed active thermal metasurface (ATMS), then use the proposed ATMS to implement a novel thermal lens with long focal length designed by transformation thermodynamics, and experimentally verify the performance of the designed long-focus thermal lens with measured focal length f=19.8mm for remote heating/cooling. The proposed method expands the scope of the thermal conductivity and open up new ways to realize unprecedented thermal effects with effective negative thermal conductivity, such as "thermal surface plasmon polaritons", thermal superlens, thermal tunneling effect, and thermal invisible gateway.

description: CD34, podocalyxin and endoglycan are cell surface sialomucins, which comprise the CD34-family of proteins. While many roles have been proposed for the CD34 family of molecules, little is known about their functions in disease. In a phenylhydrazine-induced model of anemia, we demonstrated that podocalyxin is rapidly induced on early stress erythroid progenitors, from an early BFU-E stage, through to immature reticulocytes. Our data suggest that although podocalyxin is not required for recovery from anemia, it can be used as a simple marker of stress erythroid progenitors. CD34 is expressed on mature inflammatory cells including mast cells, eosinophils and dendritic cell precursors. Interestingly, in an OVA-induced asthma model, Cd34-/- mice exhibited attenuated pathology and reduced immune cell infiltration into the alveoli and lung parenchyma. CD34 expression is present on lung and BAL eosinophils, and isolated Cd34-/- eosinophils exhibit a migration defect in vitro. These findings suggest a key role for CD34 in asthma pathology. Similarly, in a dextran sulfate sodium-induced colitis model, Cd34-/- mice exhibited significantly reduced pathology, associated with loss of CD34 expression on colon-infiltrating eosinophils. Eosinophil numbers were reduced in Cd34-/- tissues and induction of hypereosinophilia in Cd34-/- mice was sufficient to overcome the protection from DSS-induced disease. Thus, we have also demonstrated a key role for CD34 and eosinophil trafficking in ulcerative colitis. Finally, in a B16 melanoma tumor model, Cd34-/- mice exhibit altered tumor growth kinetics. At early stages, Cd34-/- mice exhibited reduced tumor size, due to loss of CD34 expression on non-hematopoietic cells (likely vascular endothelial cells). Conversely, at later timepoints, Cd34-/- mice exhibited increased tumor growth, due to loss of CD34 expression on hematopoietic cells. These findings suggest complex, opposing roles for CD34 in tumor growth due to effects on vascular integrity in early disease and immune cell-mediated tumor rejection later in the disease. These findings suggest key roles for CD34-family proteins in a range of disease states. Podocalyxin expression is induced during embryonic and stress erythropoiesis and is an indicator of anemia. CD34 plays a key role in optimal immune cell migration during asthma, colitis and tumor growth.

description: The Regge-plus-resonance (RPR) framework for kaon photoproduction on the proton and the neutron is an economical single-channel model with very few parameters. Not only does the RPR model allow one to extract resonance information from the data, it has predictive power. As an example we show that the RPR model makes fair predictions for the $p(e,e'K^{+})Λ$ and the $n(γ,K^{+})Σ^{-}$ observables starting from amplitudes optimized for the reaction $p(γ, K ^{+})Λ$ and $p(γ,K^{+})Σ^{0}$ respectively.

When-to-release Planning in Consideration of Technical Debt

subject: Project Release Management

description: Shortening release duration is a key element for creating competitive product from the iterative software development process. However, short-term expedients (e.g. code compromises, delayed change requests, etc.) can have long term effects on the future of the application. Such consequences are categorized as “technical debt”, on which “interest” (e.g. delays in implementation on sub-optimal code) have to be paid as long as the “principle” (e.g. flaws in design, documentation and implementation) is not refactored and restructured. There are multifaceted factors that influenced the effective management of technical debt in organizations. In this research, we formulate the concept of debt in the context of (software) product releases, specifically when-to-release decisions. The potential competitive advantage through faster delivery needs to be balanced against the degree of readiness of the product, evaluated based on features business values and systematic testing, and the potentially incurred technical debt. Pro-active analysis of the estimated impact of running through various release scenarios is expected to provide insights and essential inputs for actual decision-making process. This research also evaluates a set of metrics to track, maintain, and potentially reduce the types of debt created during the lifespan of the product, both as part of industry-driven case studies and quantitative evaluation using a prototype tool.
Do Machine-Learning Atomic Descriptors and Order Parameters Tell the Same Story? The Case of Liquid Water

description: Machine-learning (ML) has become a key workhorse in molecular simulations. Building an ML model in this context, involves encoding the information of chemical environments using local atomic descriptors. In this work, we focus on the Smooth Overlap of Atomic Positions (SOAP) and their application in studying the properties of liquid water both in the bulk and at the hydrophobic air-water interface. By using a statistical test aimed at assessing the relative information content of different distance measures defined on the same data space, we investigate if these descriptors provide the same information as some of the common order parameters that are used to characterize local water structure such as hydrogen bonding, density or tetrahedrality to name a few. Our analysis suggests that the ML description and the standard order parameters of local water structure are not equivalent. In particular, a combination of these order parameters probing local water environments can predict SOAP similarity only approximately, and viceversa, the environments that are similar according to SOAP are not necessarily similar according to the standard order parameters. We also elucidate the role of some of the metaparameters entering in the SOAP definition in encoding chemical information.

description: Disciplined software development involves the ad hoc reuse of source code that was not designed for that reuse. Such pragmatic reuse tasks have long been criticized due to a lack of systematic support, and an inability to validate that the reused code still provides its functionality of interest within the target system. Although recent work has successfully systematized support for pragmatic reuse tasks, validating those reuse tasks has not been tackled yet. Current approaches to validating reuse tasks require the developer to rely on automated test generation techniques which could miss serious defects, or to create his own test suite—a time consuming process whose correctness would be questioned due to the developer’s limited knowledge about the reused code. A third alternative would be to modify the originating system’s test suite to only exercise and validate the reused code. But such a manual editing process can result in injecting more defects into the originally high quality source code and its corresponding test suite. The thesis of this dissertation is that, by providing developers with tool support to reuse test cases within pragmatic reuse scenarios, we can leverage the quality of the pragmatically reused code, while reducing the needed manual intervention. To validate this claim, we have proposed a novel approach and tool to semi-automatically reuse and transform relevant portions of the test suite associated with pragmatically reused source code, as a means to validate that the relevant constraints from the originating system continue to hold, while minimizing the needed developer intervention. We have evaluated various aspects of our proposed approach, through a series of empirical studies, and using a variety of source systems and tasks. The results show that, relative to the manual approach, our approach reduces task completion time and improves the correctness of the reused test cases. Furthermore, our proposed approach can make the process of finding and fixing errors within pragmatic reuse tasks faster, and its transformed test cases can be maintained.
Conductance fluctuations in graphene devices with superconducting contacts in different charge density regimes

description: Conductions fluctuations (CF) are studied in single layer graphene devices with superconducting source and drain contacts made from aluminium. The CF are found to be enhanced by superconductivity by a factor of 1.4 to 2. This (near) doubling of the CF indicates that the phase coherence length is l_phi >= L/2. As compared to previous work, we find a relatively weak dependence of the CF on the gate voltage, and hence on the carrier density. We also demonstrate that whether the CF are larger or smaller at the charge neutrality point can be strongly dependent on the series resistance R_C, which needs to be subtracted.

description: Spin Matrix theory describes near-BPS limits of $\mathcal{N}=4$ SYM theory, which enables us to probe finite $N$ effects like D-branes and black hole physics. In previous works, we have developed the spherical reduction and spin chain methods to construct Spin Matrix theory for various limits. In this paper, by considering a supercharge $\mathcal{Q}$ which is cubic in terms of the letters, we construct the Hamiltonian of the largest Spin Matrix theory of $\mathcal{N}=4$ SYM, called the PSU$(1,2|3)$ Spin Matrix theory, as $H = \{\mathcal{Q}, \mathcal{Q}^\dagger \}$. We show the resulting Hamiltonian is automatically positive definite and manifestly invariant under supersymmetry. The Hamiltonian is made of basic blocks which transform as supermultiplets. A novel feature of this Hamiltonian is its division into D-terms and F-terms that are separately invariant under PSU$(1,2|3)$ symmetry and positive definite. As all the other Spin Matrix theories arising from $\mathcal{N}=4$ SYM can be acquired by turning off certain letters in the theory, we consider our work as revealing the "Panorama" of Spin Matrix theory.
