Nova-LSM: A Distributed, Component-based LSM-tree Key-value Store
Creators: name: Huang, Haoyu

Publisher: name: arXiv
Year: 2021
Subjects: subject: Databases (cs.DB)
subject: FOS: Computer and information sciences

description: The cloud infrastructure motivates disaggregation of monolithic data stores into components that are assembled together based on an application's workload. This study investigates disaggregation of an LSM-tree key-value store into components that communicate using RDMA. These components separate storage from processing, enabling processing components to share storage bandwidth and space. The processing components scatter blocks of a file (SSTable) across an arbitrary number of storage components and balance load across them using power-of-d. They construct ranges dynamically at runtime to parallelize compaction and enhance performance. Each component has configuration knobs that control its scalability. The resulting component-based system, Nova-LSM, is elastic. It outperforms its monolithic counterparts, both LevelDB and RocksDB, by several orders of magnitude with workloads that exhibit a skewed pattern of access to data.

description: We define a grid presentation for singular links i.e. links with a finite number of rigid transverse double points. Then we use it to generalize link Floer homology to singular links. Besides the consistency of its definition, we prove that this homology is acyclic under some conditions which naturally make its Euler characteristic vanish.

By adding the orientifold 4-plane to these brane configurations, we also discuss the meta-stable brane configurations for other gauge theory with bifundamentals. Furthermore, we study the intersecting brane configurations corresponding to the nonsupersymmetric meta-stable vacua of other gauge theory with bifundamentals, by adding the orientifold 6-plane.

description: We aim to understand the effect of stellar evolution on the evolution of protoplanetary disks. We focus in particular on the disk evolution around intermediate-mass (IM) stars, which evolve more rapidly than low-mass ones. We numerically solve the long-term evolution of disks around 0.5-5 solar-mass stars considering viscous accretion and photoevaporation (PE) driven by stellar far-ultraviolet (FUV), extreme-ultraviolet (EUV), and X-ray emission. We also take stellar evolution into account and consider the time evolution of the PE rate. We find that the FUV, EUV, and X-ray luminosities of IM stars evolve by orders of magnitude within a few Myr along with the time evolution of stellar structure, stellar effective temperature, or accretion rate. Therefore, the PE rate also evolves with time by orders of magnitude, and we conclude that stellar evolution is crucial for the disk evolution around IM stars.

The diffeomorphism group of a K3 surface and Nielsen realization

description: The Nielsen Realization problem asks when the group homomorphism from Diff(M) to pi_0 Diff(M) admits a section. For M a closed surface, Kerckhoff proved that a section exists over any finite subgroup, but Morita proved that if the genus is large enough then no section exists over the entire mapping class group. We prove the first nonexistence theorem of this type in dimension 4: if M is a smooth closed oriented 4-manifold which contains a K3 surface as a connected summand then no section exists over the whole of the mapping class group. This is done by showing that certain obstructions lying in the rational cohomology of B(pi_0 Diff(M)) are nonzero. We detect these classes by showing that they are nonzero when pulled back to the moduli space of Einstein metrics on a K3 surface.
description: 20 pages, published version. ERRATUM: This paper is withdrawn. As pointed out by Bena Tshishiku, Borel's theorem on the cohomology stable range for arithmetic groups is incorrectly quoted and applied in this paper; in the case relevant to K3 surfaces the range is unfortunately zero. Hence the proof of the part of Theorem 1.1 referring to K3 surfaces is fundamentally broken. See arXiv:1711.03139

description: We investigate flux-grown Sm-deficient Sm$_x$B$_6$ ($x < 1$) by global and local tools, including X-ray diffraction (XRD), electronic transport, and scanning tunneling microscopy (STM) and spectroscopy (STS). All these tools indicate a remarkable persistence of the SmB$_6$ local structure in the flux-grown samples even for nominal Sm concentrations as low as $x=0.75$. As a consequence, the overall electronic properties of Sm$_x$B$_6$, and particularly the surface conductance at low temperature, is only affected locally by the Sm-deficiency.

Political bargaining and the Punjab crisis : the Punjab Accord of 1985
Creators: name: Rodríguez, Alvaro Joseph
Publisher: name: University of British Columbia
Year: 2010

description: Since the early 1980's, the Punjab state of India has been in turmoil as a result of a separatist movement that developed among elements of the Sikh community. Political tensions not only characterized the relationship between the Punjab and New Delhi/ but also between Sikhs and Hindus and among different segments within the Sikh community itself. The most important attempt to end the conflict in the state has been the Rajiv Gandhi-Sant Longowal Accord signed on July 24, 1985. However, the Accord failed and by mid-1987 the Punjab was once again racked by political violence. This thesis focuses on the events that led to the signing of the Accord and the forces that caused its demise. Bargaining theory provides the general theoretical framework against which the data are analyzed. This thesis highlights the fact that political bargains in Third World weakly-institutionalized states are often the result of particular configurations of political power which are short lived. The corollary of this is that once the configuration of political forces changes, the chances of success for the previously reached political bargain are weakened. In the particular case of the Punjab Accord, there was a change, beginning in late 1985, in the relative political power of the participants in the bargain. Also, the terms of the bargained Accord unleashed forces on both sides which undermined its implementation. Third World leaders should draw two major lessons from this. First, they should be careful not to have exaggerated perceptions of their power since this may be counterproductive in the future if they cannot deliver what they have promised. Second, these leaders should attempt to consult all interests with a stake in the bargained settlement as a way to prevent opposition to it.
Renormalized Quantum Yang-Mills Fields in Curved Spacetime

description: We present a proof that quantum Yang-Mills theory can be consistently defined as a renormalized, perturbative quantum field theory on an arbitrary globally hyperbolic curved, Lorentzian spacetime. To this end, we construct the non-commutative algebra of observables, in the sense of formal power series, as well as a space of corresponding quantum states. The algebra contains all gauge invariant, renormalized, interacting quantum field operators (polynomials in the field strength and its derivatives), and all their relations such as commutation relations or operator product expansion. It can be viewed as a deformation quantization of the Poisson algebra of classical Yang-Mills theory equipped with the Peierls bracket. The algebra is constructed as the cohomology of an auxiliary algebra describing a gauge fixed theory with ghosts and anti-fields. A key technical difficulty is to establish a suitable hierarchy of Ward identities at the renormalized level that ensure conservation of the interacting BRST-current, and that the interacting BRST-charge is nilpotent. The algebra of physical interacting field observables is obtained as the cohomology of this charge. As a consequence of our constructions, we can prove that the operator product expansion closes on the space of gauge invariant operators. Similarly, the renormalization group flow is proved not to leave the space of gauge invariant operators.

Year: 2015

description: In the years after the 1905–1907 revolution, Social Democrats operated in the political shadows and turned much of their energy to internal differences of strategy and philosophy. Lenin took the issues of Marxist philosophical orthodoxy on questions of materialist ontology so seriously that he was willing to break off his relationship with one of his most talented comrades, Bogdanov, and create a schism in the diminished Bolshevik ranks. Stalin, then a minor figure in the party leadership, was a moderate in this debate and pushed for reconciliation and unity in the Bolshevik faction.

Yrjö Mäkelin’s Choice
Creators: name: Saarela, Tauno
Publisher: name: Moving the Social
Year: 2015

description: The division of the Finnish labour movement is studied in this article through the choice of Yrjö Mäkelin, one of the prominent members of the Finnish labour movement since its foundation. Yrjö Mäkelin made his choice in the beginning of 1922, when he was released from the prison where he had spent almost four years. During that time the Finnish labour movement had been divided, and Mäkelin had to ponder on which party to choose. Mäkelin’s earlier career, especially his wish to get the labour movement to work together with the bourgeois parties in order to achieve independence for Finland, would have suggested that he join the Social Democratic Party; but he decided to enter the ranks of the Socialist Workers’ Party which had contacts with the underground Communist Party. Although Mäkelin was not a very active participant in the abortive revolution and in the civil war in the winter and spring of 1918, it was an important factor in his decision. The stance of his family and the whole labour movement in the northern Finland also had an influence on Mäkelin’s choice. He, however, emphasised that he would join the Socialist Workers’ Party while following his own programme, which expressed doubts about the ideas of centralisation and strict discipline the communist movement had launched. He stayed within the party, although the leaders of the Communist Party wanted to expel him.

West German trade unions and the policy of détente (1969 – 1989)
Creators: name: Müller, Stefan
Publisher: name: Moving the Social
Year: 2015

description: This article discusses the contacts of the West German Trade Union Federation (DGB) to the communist state unions of the Warsaw Pact in the period of détente (1969 to 1989). How were these contacts embedded into West German foreign policy? It is argued that the DGB voluntarily acted as a state agent and not as a non governmental organisation (NGO). The initial aim of 1969 was to support the controversial West German Ostpolitik in the public and to prevent communist influence on West German society. However, the support of the West German trade unions was not directly linked to the Social Democratic Party (SPD). The DGB’s policy continued after the change of Government in 1982. First, the article examines the changing East West trade unions relations from the 1970s to the 1980s; second, it analyses the trade union support of government’s foreign policy and its relations to West German state agencies in the 1970s and 1980s. Finally, it discusses the consequences for the conceptualisation of NGOs and for transnational history.

description: Mixed-Criticality (MC) systems have recently been devised to address the requirements of real-time systems in industrial applications, where the system runs tasks with different criticality levels on a single platform. In some workloads, a high-critically task might overrun and overload the system, or a fault can occur during the execution. However, these systems must be fault-tolerant and guarantee the correct execution of all high-criticality tasks by their deadlines to avoid catastrophic consequences, in any situation. Furthermore, in these MC systems, the peak power consumption of the system may increase, especially in an overload situation and exceed the processor Thermal Design Power (TDP) constraint. This may cause generating heat beyond the cooling capacity, resulting the system stop to avoid excessive heat and halting the processor. In this paper, we propose a technique for dependent dual-criticality tasks in fault-tolerant multi-core MC systems to manage peak power consumption and temperature. The technique develops a tree of possible task mapping and scheduling at design-time to cover all possible scenarios and reduce the low-criticality task drop rate in the high-criticality mode. At run-time, the system exploits the tree to select a proper schedule according to fault occurrences and criticality mode changes. Experimental results show that the average task schedulability is 74.14% on average for the proposed method, while the peak power consumption and maximum temperature are improved by 16.65% and 14.9 C on average, respectively, compared to a recent work. In addition, for a real-life application, our method reduces the peak power and maximum temperature by up to 20.06% and 5 C, respectively, compared to a state-of-the-art approach.

Socialist Parties’ agenda-setting in European community development aid policy in the early 1970s: Objectives, strategies and limits of implementation
Creators: name: Salm, Christian
Publisher: name: Moving the Social
Year: 2015

description: This article addresses the role of transnational socialist party cooperation in setting the agenda of the European Community (EC) in the policy field of development aid in the early 1970s. Although agenda-setting has a high relevance for understanding why certain issues are successfully inserted in the EC (later the European Union) policy-making cycle while others not, this important stage of political decision-making often tends to escape our attention. The article argues that socialist transnational party cooperation through networks on the European level developed various strategies for placing development aid issues on the EC agenda. However, the article also shows that with a view to implementation there were several reasons that made it difficult for transnational socialist party cooperation to push forward development aid issues in the cycle of EC policy-making beyond agenda-setting.

Liberalism in Lower Canada, 1774-1815
Creators: name: Robert, Louise
Publisher: name: University of British Columbia
Year: 2010

description: The historians characterizing Lower Canada's thought in the period before 1815 have argued that it was principally nationalist. French Canadians, moreover, were assessed either as clinging to the values and precepts of a feudal past or as adopting advanced republican ideas. In neither case, however, was attention paid to the articulation by French Lower Canadians of a system of thought that reflected the complex reality of the society in which they lived. This thesis attempts to recreate the system of thought using the public writings of the most politically active members of the community. It analyses the various intellectual influences on the colony and the unique mixture arrived at by the commentators who were affected by them. Having, it argues, combined elements of thinking drawn from the old regime, the Enlightenment and British writers and statesmen, French Canadians devised an idea of community which reflected their society's bicultural and bilingual nature and articulated the nature of the participation of its members in their newly acquired parliamentary institutions. Far, then, from being dissaffected with the existing structures or showing a desire for independence, they comprised an active and politically aware population which viewed its future as intimately tied to the Constitution and to the British Empire.

Abstract: Electronics are shrinking andpenetrating all aspects of our lives. The Internet of Things fills our homes and cars, body area networks monitor our health.  Our data is store on cloud and edge computers.  Adding security and cryptography to these highly complex and often very resource constraint systemsis a challenge. We would like the security solutions to be lightweight and at the same time resistant to a broad range of attacks. Attacker models can vary wildly including remote as well as local physical manipulation attacks.  The most difficult part for the designer is to decide which parts of such a complex system need protection. This includes defining the essential roots of trust.  Software and cryptographic security protocols rely on hardware roots of trust.  In this presentation, we will give our definition of a root of trust and how to use it in a complex system. Next, we will illustrate this with two essential roots of trust: physically unclonable functions (PUFs) and True Random Number Generators (TRNGs).  In this presentation, we will describe different design options, and put special attention the security evaluation and test.  BIO: Dr. Ir.

description: As was noted already by A. N. Kolmogorov, any random variable has a Bernoulli component. This observation provides a tool for the extension of results which are known for Bernoulli random variables to arbitrary distributions. Two applications are provided here: i. an anti-concentration bound for a class of functions of independent random variables, where probabilistic bounds are extracted from combinatorial results, and ii. a proof, based on the Bernoulli case, of spectral localization for random Schroedinger operators with arbitrary probability distributions for the single site coupling constants. For a general random variable, the Bernoulli component may be defined so that its conditional variance is uniformly positive. The natural maximization problem is an optimal transport question which is also addressed here.

description: We prove an area law for the entanglement entropy in gapped one dimensional quantum systems. The bound on the entropy grows surprisingly rapidly with the correlation length; we discuss this in terms of properties of quantum expanders and present a conjecture on completely positive maps which may provide an alternate way of arriving at an area law. We also show that, for gapped, local systems, the bound on Von Neumann entropy implies a bound on Rényi entropy for sufficiently large $α<1$ and implies the ability to approximate the ground state by a matrix product state.

description: Citation based measures are widely used as quantitative proxies for subjective factors such as the importance of a paper or even the worth of individual researchers. Here we analyze the citation histories of $4669$ papers published in journals of the American Physical Society between $1960$ and $1968$ and argue that state-of-the-art models of citation dynamics and algorithms for forecasting nonstationary time series are very likely to fail to predict the long-term ($50$ years after publication) citation counts of highly-cited papers using citation data collected in a short period (say, $10$ years) after publication. This is so because those papers do not exhibit distinctive short-term citation patterns, although their long-term citation patterns clearly set them apart from the other papers. We conclude that even if one accepts that citation counts are proxies for the quality of papers, they are not useful evaluative tools since the short-term counts are not informative about the long-term counts in the case of highly-cited papers.
Murder by slander? : a re-examination of the E.H. Norman case
Creators: name: Rogers, Ann C. M.
Publisher: name: University of British Columbia
Year: 2010

description: On 4 April, 1957 Egerton Herbert Norman, Canada's Ambassador to Egypt, committed suicide in Cairo. Norman's death was a direct result of sustained American allegations that he was threat to western security. The controversy surrounding his suicide was rekindled in 1986 with the publication of two biographies of Norman. James Barros contends in No Sense of Evil that Norman should have been removed from his high position in Canada's Department of External Affairs because he constituted a security risk. Barros hypothesises about the possibility of a DEA cover-up of Norman's Marxist past (Norman had briefly been a member of the British Communist Party when he was a student at Cambridge) and indeed suggests that Minister of External Affairs, Lester B. Pearson might have been Moscow's ultimate 'mole' who, by defending Norman, was protecting his espionage ring. In Innocence is Not Enough, author Roger Bowen takes issue with such interpretations of Norman's life, scholarship and career. Although Norman had been a Communist, Bowen concludes that no evidence exists to suggest that he was disloyal to Canada. Norman was caught up in a maelstrom of anti-communist hysteria which caused him to be unjustifiably vilified and harassed by the agents of McCarthyism in an era of Cold War paranoia. Instead of choosing a side in the current debate, I have sought to widen it by approaching the story of Norman as a case study in Canadian foreign policy. An examination of Canadian internal security policies in the postwar era, Canada's relationship with the United States and Great Britain, and of Norman himself reveals that the issue at hand is far too complex to be amenable to easy analysis. This thesis was written with the achievement of a more objective analysis as its primary goal.

description: The phase coherence of an ultrastable optical frequency reference is fully maintained over actively stabilized fiber networks of lengths exceeding 30 km. For a 7-km link installed in an urban environment, the transfer instability is $6 \times 10^{-18}$ at 1-s. The excess phase noise of 0.15 rad, integrated from 8 mHz to 25 MHz, yields a total timing jitter of 0.085 fs. A 32-km link achieves similar performance. Using frequency combs at each end of the coherent-transfer fiber link, a heterodyne beat between two independent ultrastable lasers, separated by 3.5 km and 163 THz, achieves a 1-Hz linewidth.

description: We discuss theoretically the properties of an electromechanical oscillator whose operation is based upon the cyclic, quasi-conservative conversion between gravitational potential, kinetic, and magnetic energies. The system consists of a strong-pinning type-II superconductor square loop subjected to a constant external force and to magnetic fields. The loop oscillates in the upright position at a frequency that can be tuned in the range 10-1000 Hz, and has induced in it a rectified electrical current. The emphasis of this paper is on the evaluation of the major remaining source of losses in the oscillations. We argue that such losses should be associated with the viscous vibration of pinned flux lines in the superconductor Nb-Ti wire, provided the oscillator is kept close to zero Kelvin, under high-vacuum, and the magnetic field is sufficiently uniform. We discuss how other different sources of loss would become negligible for such operational conditions, so that a very high quality factor Q exceeding 10^(10) might in principle be reached by the oscillator. The prospective utilization of such oscillator as a low-frequency high-Q clock is analyzed.Since publication the ideas in this paper have been explored both by the author and elsewhere, in applications covering Metrology, quantum systems, and gravimetry.

description: Handwritten character recognition is a challenging research in the field of document image analysis over many decades due to numerous reasons such as large writing styles variation, inherent noise in data, expansive applications it offers, non-availability of benchmark databases etc. There has been considerable work reported in literature about creation of the database for several Indic scripts but the Tamil script is still in its infancy as it has been reported only in one database [5]. In this paper, we present the work done in the creation of an exhaustive and large unconstrained Tamil Handwritten Character Database (uTHCD). Database consists of around 91000 samples with nearly 600 samples in each of 156 classes. The database is a unified collection of both online and offline samples. Offline samples were collected by asking volunteers to write samples on a form inside a specified grid. For online samples, we made the volunteers write in a similar grid using a digital writing pad. The samples collected encompass a vast variety of writing styles, inherent distortions arising from offline scanning process viz stroke discontinuity, variable thickness of stroke, distortion etc. Algorithms which are resilient to such data can be practically deployed for real time applications. The samples were generated from around 650 native Tamil volunteers including school going kids, homemakers, university students and faculty. The isolated character database will be made publicly available as raw images and Hierarchical Data File (HDF) compressed file. With this database, we expect to set a new benchmark in Tamil handwritten character recognition and serve as a launchpad for many avenues in document image analysis domain. Paper also presents an ideal experimental set-up using the database on convolutional neural networks (CNN) with a baseline accuracy of 88% on test data.

Abstract: With datacenters mushrooming around each other to provide the necessary bandwidth for our computing and communication needs, the need to interconnect them with optical fibers at low cost and high energy efficiency has significantly increased. Coherent silicon photonic links bear the promise to satisfy that demand at an unprecedented scale, integration, and (low) cost. In this talk, I will briefly introduce coherent silicon photonics, draw parallels to wireless radio transceivers, describe the photonics and electronics details of 16-QAM coherent links operating at 0.5Tb/s, and comment on some of the subsequent research opportunities in bringing coherent links inside the datacenters.
Unifying derived deformation theories

description: We develop a framework for derived deformation theory, valid in all characteristics. This gives a model category reconciling local and global approaches to derived moduli theory. In characteristic 0, we use this to show that the homotopy categories of DGLAs and SHLAs (L infinity algebras) considered by Kontsevich, Hinich and Manetti are equivalent, and are compatible with the derived stacks of Toen--Vezzosi and Lurie. Another application is that the cohomology groups associated to any classical deformation problem (in any characteristic) admit the same operations as Andre--Quillen cohomology.

description: We show that the transition probability of the Markoc chain $(G(j,1),...,G(j,n))_{j\ge 1}$, where the $G(i,j)'s$ are certain directed last-passage times, is given by a determinant of a special form. An analogous formula has recently been obtained by Warren in a Brownian motion model. Furthermore we demonstrate that this formula leads to the Meixner ensemble when we compute the distribution function for $G(m,n)$. We also obtain the Fredholm determinant representation of this distribution, where the kernel has a double contour integral representation.

description: This paper discusses a new variant of the Henry Gas Solubility Optimization (HGSO) Algorithm, called Hybrid HGSO (HHGSO). Unlike its predecessor, HHGSO allows multiple clusters serving different individual meta-heuristic algorithms (i.e., with its own defined parameters and local best) to coexist within the same population. Exploiting the dynamic cluster-to-algorithm mapping via penalized and reward model with adaptive switching factor, HHGSO offers a novel approach for meta-heuristic hybridization consisting of Jaya Algorithm, Sooty Tern Optimization Algorithm, Butterfly Optimization Algorithm, and Owl Search Algorithm, respectively. The acquired results from the selected two case studies (i.e., involving team formation problem and combinatorial test suite generation) indicate that the hybridization has notably improved the performance of HGSO and gives superior performance against other competing meta-heuristic and hyper-heuristic algorithms.

description: The probability distribution of the closest neighbor and farther neighbor spacings from a given level have been studied for interacting fermion/boson systems with and without spin degree of freedom constructed using an embedded GOE of one plus random two-body interactions. Our numerical results demonstrate a very good consistency with the recently derived analytical expressions using a $3 \times 3$ random matrix model and other related quantities by Srivastava et. al [{\it J. Phys. A: Math. Theor.} {\bf 52} 025101 (2019)]. This establishes conclusively that local level fluctuations generated by embedded ensembles (EE) follow the results of classical Gaussian ensembles.

description: We investigated the transport titanium ions produced in a reactive high-power impulse magnetron sputtering (HiPIMS) device used for TiN coating deposition. Time-resolved mass spectrometry measurements of ionized sputtered atoms correlated to time-resolved tuneable diode-laser induced fluorescence (TR-TDLIF) measurements of neutral sputtered atoms were used to understand transport features. Based on ion energy distributions of Ti$^+$, we identified four populations of ions and explore their physical origins. The signals of all ion populations decrease strongly when only 1% N$_2$ is added to the Ar/N$_2$ gas mixture. Time resolved mass spectrometry confirms the result reported in previous work: the fast target poisoning when nitrogen is added in HiPIMS discharges. Based on the measured energy distribution functions of Ti$^{++}$, N$^+$, N$_2^+$, and Ar$^+$, we discuss the production of these ions in HiPIMS discharges. The temperature of thermalized sputtered neutral atoms determined by previous TR-TDLIF measurements evidences the physical origin of an ion population with energies lower than 4 eV. According to discharge pressure, cathode voltage, and ion type, we also discuss the physical origins of high-energy ions (>4 eV).

Anthropic prediction in a large toy landscape

Year: 2007
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: The successful anthropic prediction of the cosmological constant depends crucially on the assumption of a flat prior distribution. However, previous calculations in simplified landscape models showed that the prior distribution is staggered, suggesting a conflict with anthropic predictions. Here we analytically calculate the full distribution, including the prior and anthropic selection effects, in a toy landscape model with a realistic number of vacua, $N \sim 10^{500}$. We show that it is possible for the fractal prior distribution we find to behave as an effectively flat distribution in a wide class of landscapes, depending on the regime of parameter space. Whether or not this possibility is realized depends on presently unknown details of the landscape.

description: We compute energy distributions of three particles emerging from decaying many-body resonances. We reproduce the measured energy distributions from decays of two archetypal states chosen as the lowest $0^{+}$ and $1^{+}$-resonances in $^{12}$C populated in $β$-decays. These states are dominated by sequential, through the $^{8}$Be ground state, and direct decays, respectively. These decay mechanisms are reflected in the ``dynamic'' evolution from small, cluster or shell-model states, to large distances, where the coordinate or momentum space continuum wavefunctions are accurately computed.

description: The D4-D8 brane system of Sakai-Sugimoto model at high quark density is studied in the weak coupling regime. We show that the color superconducting phase (for Nc~3) or the chiral density wave (for Nc->infinity) disappears at very large chemical potential, or equivalently at very large compactified dimension that the model possesses. We also comment on the prospects in the strong coupling regime along with the QCD phase diagram.
