Parametrically-enhanced nuclear magnetic resonance spectrometer prototype
Creators: name: Wong, Kenneth
Publisher: name: The University of British Columbia
Year: 2011

description: This project evaluates the feasibility of using a strong alternating magnetic field, in addition to the Earth’s weaker magnetic field, to improve nuclear magnetic resonance spectroscopy. In this new method of NMR spectroscopy devised by Prof. Michal, an electromagnet, instead of the Earth, is used to generate static magnetic field. A solenoidal coil produces a magnetic field strength of approximately 2.35 mT, over 40 times greater than that of the Earth. The stronger static magnetic field is expected to increase the signal-to-noise ratio of the NMR signal by more than 700 times over traditional Earth’s field NMR. The objective of this project is to produce an engineering prototype demonstrating parametrically enhanced NMR spectroscopy. The prototype consists of a transmitter coil to generate the alternating static magnetic field, a receiver coil to detect the Larmor precession of the test specimen, and an electronic circuit to filter and amplify the NMR signal. By using an alternating static magnetic field, the detrimental spin dephasing caused by field inhomogeneities can be reduced. The prototype necessitates relatively inexpensive components and maintains a portable form factor. In developing the prototype, the transmitter coil and the receiver coil has been fabricated and characterized. After evaluating the two proposed waveforms for driving the transmitter coil, the sinusoidal waveform is selected and a circuit has been designed and breadboarded. The NMR signal processing circuit successfully rejects 37 dB of the offending noise signal to theoretically allow the Larmor precession to be discerned. Due to unforeseen distortion in the output signal of the power amplifier, the specified static magnetic field strength cannot be achieved. As a result, the parametrically enhanced NMR spectrometer prototype has not been realized within the project timeframe. Several recommendations are suggested to correct the identified problems and improve the current design. With additional development, this novel NMR spectroscopy method can be developed into inexpensive and portable NMR spectroscopy applications.
Recommendation report for an infrared eye-tracking system for P-Cubee

Year: 2011

description: There are several techniques that can be employed to track real-time eye movements. Currently, pCubee uses magnetic sensor technology and requires the user to wear a head-tracking sensor that is wired to the device itself. The objective of the project was to construct a wireless, noninvasive, low-latency infrared eye tracking system that could replace the existing solution. The technique that was utilized in this project involved processing of images from a video-based method, which can be performed with inexpensive cameras. A two camera system was setup and calibrated successfully. Triangulation was tested with IR goggles and the accuracy of the system was determined to be less than 1%. Thus, proof of concept was demonstrated and it should not be difficult to extend the system to function with any two camera configuration, provided that the appropriate common field of view is produced. An algorithm was developed to search for the location of the red-eye effect in a subject’s eyes. However, based on the images gathered from the camera setup, the red-eye effect was not strong enough to be detectable. A difference image technique was also employed to improve the detection of the red-eye effect, but did not yield better results. There were many limitations or sources of error that prevented the system to be designed optimally. The investigators believe there are several improvements - such as utilizing higher quality cameras and better image processing techniques - that could be made to successfully complete the system.

description: Whether in fundamental physics, cybersecurity or finance, the detection of anomalies with machine learning techniques is a highly relevant and active field of research, as it potentially accelerates the discovery of novel physics or criminal activities. We provide a systematic analysis of the generalization properties of the One-Class Support Vector Machine (OCSVM) algorithm, using projected quantum kernels for a realistic dataset of the latter application. These results were both theoretically simulated and experimentally validated on trapped-ion and superconducting quantum processors, by leveraging partial state tomography to obtain precise approximations of the quantum states that are used to estimate the quantum kernels. Moreover, we analyzed both platforms respective hardware-efficient feature maps over a wide range of anomaly ratios and showed that for our financial dataset in all anomaly regimes, the quantum-enhanced OCSVMs lead to better generalization properties compared to the purely classical approach. As such our work bridges the gap between theory and practice in the noisy intermediate scale quantum (NISQ) era and paves the path towards useful quantum applications.

description: The increasing performance of lithium-ion batteries and the continuous emergence of new manufacturers, formats, and cell chemistries enable the electrification of more applications. However, this heterogeneity and complexity make it difficult to anticipate all viable battery cells for specific applications. This paper presents a high-level techno-economic approach to identifying suitable battery cells for different applications. The methodology is based on an extensive cell database containing more than 350 real-world cells, the techno-economic characterization of emerging battery-relevant applications, and a Python-based model. This allows matching the application requirements to each battery cell performance to determine cell-specific cost-parity prices. We showcase the approach for passenger cars, forklifts, and passenger trains. Our results highlight large differences among applications in technical requirements and needed cost-parity prices, emphasizing the importance of tailored techno-economic cell selection.

"Breeze farmer" : an open-source bike-wheel wind turbine

Year: 2011

description: Geopolitical and environmental concerns means the demand for alternative energies will continue to rise, but the largest inhibiting factor right now is cost as compared to cheap oil. To avoid environmental catastrophe, inexpensive solutions need to become available: distributed power generation, from a ubiquitous energy source such as wind, has the potential to fill this gap. However, the average household wind is typically slow for most of the year, so turbines need to be efficient and low-friction to take advantage of these slow winds. Since most mechanical friction results from the complexities of the hub and shaft assembly, where power is typically generated in most turbines, a key design feature would be to make the hub as simple as possible so that it spins freely like a bicycle wheel. This outer-rim induction is the basis for our project Breeze Farmer, an open-source home wind turbine that is designed to be assembled cheaply out of parts like a used bicycle wheel. Wind blades are first mounted onto the wheel, which itself can be mounted onto a rotating frame so that the wheel is always perpendicular to the wind. The induction required to convert mechanical to electrical energy takes place around the rim of the wheel, where a number of magnets are mounted. As these pass by inductor coils mounted onto a stator wheel frame mounted right behind, alternating current is produced. This induction will slow down the wheel, but since this drag is purely electromagnetic and not mechanical, it should be at a theoretical minimum. The current is fed into a circuit which converts it to DC, which can then be used to charge a 12V battery. This is but one possible application for the current produced. The Breeze Farmer prototype was constructed and tested in the Engineering Physics Project Lab. It was sponsored by Bernhard Zender of the same lab, who came up with the project idea. Breeze Farmer is based on the design of the far more expensive Honeywell Wind Turbine, but aims to be a cheap do-it-yourself endeavor. The prototyping project consisted of several different configurations of magnets, inductors, blade material and shape, and other variables in order to derive the most efficient setup for maximal power generation with a minimal start speed. These metrics were probed using very basic measurements of wind speed, rotational speed, load, and rectified power. After developing a Breeze Farmer prototype, it has been found that, with a reasonable number of magnets and many coils, the electrical power generated is rather small. Large factor of this is power losses in eddy currents in our aluminum stator rim, and losses in the coil conductors.

description: In this study the dynamic characteristics of steel and plastic conveyor belts regarding belt vibrations were carried out. The analysis showed major differences between the different materials as the measured vibrations of the plastic belt were four to six times higher compared to the steel belt. Further­more, a reduction of vibrations with an increasing belt speed was determined for both belt types. We further investigated whether a local reduction of belt vibrations is possible by using air bearings. The tests showed a reduction for both belt types. The use of air bearings in combination with a steel belt could be carried out successfully. In contrast, running noises were detected with the plastic belt used. This is attributed to a non-stable air film due to a rough running surface. The suitability of alternative plastic belts with a smooth running surface must be examined. In the last part of the study a reduction of belt vibrations has been determined by increasing the of belt tension using a steel belt.

description: Ciminion and Hydra are two recently introduced symmetric key Pseudo-Random Functions for Multi-Party Computation applications. For efficiency, both primitives utilize quadratic permutations at round level. Therefore, polynomial system solving-based attacks pose a serious threat to these primitives. For Ciminion, we construct a quadratic degree reverse lexicographic (DRL) Gröbner basis for the iterated polynomial model via linear transformations. With the Gröbner basis we can simplify cryptanalysis, as we no longer need to impose genericity assumptions to derive complexity estimates. For Hydra, with the help of a computer algebra program like SageMath we construct a DRL Gröbner basis for the iterated model via linear transformations and a linear change of coordinates. In the Hydra proposal it was claimed that $r_\mathcal{H} = 31$ rounds are sufficient to provide $128$ bits of security against Gröbner basis attacks for an ideal adversary with $ω= 2$. However, via our Hydra Gröbner basis standard term order conversion to a lexicographic (LEX) Gröbner basis requires just $126$ bits with $ω= 2$. Moreover, using a dedicated polynomial system solving technique up to $r_\mathcal{H} = 33$ rounds can be attacked below $128$ bits for an ideal adversary.

description: Flow and mass cytometry are experimental techniques used for the characterization of cell phenotypes. With the increase of usable cell markers (up to 50 markers), the identification of cell populations through manual gating is impossible. These high-dimensional data require new computational algorithms to automatically identify cell clusters. The SPADE algorithm has been proposed as a new way to analysis and explore mass-cytometry data. This algorithm performs a density-based down-sampling combined with an agglomerative hierarchical clustering.

While SPADE offers new opportunities for identifying cell populations, complementary approaches are needed to improve the characterization of identified cell populations. We present here SPADEVizR, an R package to better visualize and analyze SPADE clustering results. We extended the original SPADE outputs with techniques such as parallel coordinates, heatmaps, multidimensional scaling, volcano plots or streamgraph representations. Moreover, the proposed statistical methods allow the identification of SPADE clusters with relevant biological behaviors. For instance, significantly abundant clusters or differentially enriched clusters can be identified using SPADEVizR. In addition, the integration of cell cluster behaviors with additional phenotypical variables can be performed.

We illustrate the capabilities of our R package using a dataset of 15 cytometry profiles with 27 markers each, obtained in the context of a MVA macaque vaccine study. SPADEVizR has been designed in a way that it can be easily used by non bioinformatician experts, but can also be easily customizable by users with more expertise in bioinformatics. Through the multiple visualization and analysis features, SPADEVizR is also a powerful analysis pipeline for high-dimensional cytometry data.

description: Recent advances in quantum computers are demonstrating the ability to solve problems at a scale beyond brute force classical simulation. As such, a widespread interest in quantum algorithms has developed in many areas, with optimization being one of the most pronounced domains. Across computer science and physics, there are a number of algorithmic approaches, often with little linkage. This is further complicated by the fragmented nature of the field of mathematical optimization, where major classes of optimization problems, such as combinatorial optimization, convex optimization, non-convex optimization, and stochastic extensions, have devoted communities. With these aspects in mind, this work draws on multiple approaches to study quantum optimization. Provably exact versus heuristic settings are first explained using computational complexity theory - highlighting where quantum advantage is possible in each context. Then, the core building blocks for quantum optimization algorithms are outlined to subsequently define prominent problem classes and identify key open questions that, if answered, will advance the field. The effects of scaling relevant problems on noisy quantum devices are also outlined in detail, alongside meaningful benchmarking problems. We underscore the importance of benchmarking by proposing clear metrics to conduct appropriate comparisons with classical optimization techniques. Lastly, we highlight two domains - finance and sustainability - as rich sources of optimization problems that could be used to benchmark, and eventually validate, the potential real-world impact of quantum optimization.

description: Layered two-dimensional (2D) materials exhibit unique properties, expanding opportunities in material design. We investigate MX$_2$ transition metal dichalcogenides (TMDCs) (M = Mo, W; X = S, Se, Te) in homo- and heterobilayers with different stacking and twist angles. Twisted bilayers introduce Moiré patterns, significantly altering electronic properties. Using first-principles Density Functional Theory (DFT) with range-separated hybrid functionals, we examine 30 MX$_2$ combinations, revealing how stacking and composition influence stability and band gap energy (E$_g$). Notably, the MoTe$_2$/WSe$_2$ heterostructure with a 60\textdegree~shift maintains a direct band gap, highlighting its potential for applications. Homobilayers under low-strain conditions exhibit diverse stacking-dependent electronic behaviors, where MoS$_2$, WS$_2$, and WSe$_2$ transition between direct and indirect band gaps at specific twist angles. MoS$_2$ can even switch between semiconductor and metallic states. Critical twist angles (17.9\textdegree, 42.1\textdegree, 77.9\textdegree, and 102.1\textdegree) in twisted WS$_2$ and WSe$_2$ bilayers yield symmetric Moiré patterns with tunable band gaps. Our findings emphasize that controlling heterostructures and twist angles is a powerful strategy for engineering electronic properties, offering a pathway for next-generation materials.

description: Quantum search algorithms, such as Grover's algorithm, are anticipated to efficiently solve constrained combinatorial optimization problems. However, applying these algorithms to the traveling salesman problem (TSP) on a quantum circuit presents a significant challenge. Existing quantum search algorithms for the TSP typically assume that an initial state -- an equal superposition of all feasible solutions satisfying the problem's constraints -- is pre-prepared. The query complexity of preparing this state using brute-force methods scales exponentially with the factorial growth of feasible solutions, creating a significant hurdle in designing quantum circuits for large-scale TSPs. To address this issue, we propose a two-step quantum search (TSQS) algorithm that employs two sets of operators. In the first step, all the feasible solutions are amplified into their equal superposition state. In the second step, the optimal solution state is amplified from this superposition state. The TSQS algorithm demonstrates greater efficiency compared to conventional search algorithms that employ a single oracle operator for finding a solution within the encoded space. Encoded in the higher-order unconstrained binary optimization (HOBO) representation, our approach significantly reduces the qubit requirements. This enables efficient initial state preparation through a unified circuit design, offering a quadratic speedup in solving the TSP without prior knowledge of feasible solutions.

description: Antimony sulfide (Sb2S3 ) has gained extensive attention in solar cells due to their potential as a low-cost and earth abundant absorber material. In solar cell absorber, the optoelectrical properties such as energy band gap and absorption coefficient of Sb2S3 play an important role, which have strong relationships with their crystal structure, lattice parameter and crystallite size. Hence in the present investigation, Sb2S3 powder samples were exposed to biofield treatment, and further its physical, structural and spectral properties are investigated. The particle size analysis showed larger particle size and surface area after treatment. X-ray diffraction (XRD) analysis revealed polycrystalline orthorhombic structure with superior crystallinity in treated Sb2S3 along with significant changes in the lattice parameters, which led to changes in unit cell volume and density. XRD data analysis indicates that crystallite size was increased by around 150% in treated sample. In FT-IR spectra, strong absorption band was observed at 400-700cm -1 , which confirms the presence of Sb2S3 . Further, the absorption peak intensity in IR spectra was significantly reduced after treatment that was probably due to change in metal sulphur dipolar interaction.

description: Barium titanate, perovskite structure is known for its high dielectric constant and piezoelectric properties, which makes it interesting material for fabricating capacitors, transducer, actuator, and sensors. The perovskite crystal structure and lattice vibrations play a crucial role in its piezoelectric and ferroelectric behavior. In the present study, the barium titanate powder was subjected to biofield treatment. Further, the control and treated samples were characterized using X-ray diffraction (XRD) and Fourier transform infrared spectrometer (FT-IR) and Electron spin resonance (ESR). The XRD analysis showed the permanent compressive strain of 0.45% in treated barium titanate powder as compared to control. Furthermore, the biofield treatment has enhanced the density upto 1.38% in barium titanate as compared to control. The FT-IR spectra showed that the stretching and bending vibrations of Ti-O bond in treated BaTiO3 were shifted towards lower frequency as compared to control. The bond length was substantially increased by 0.72 % in treated BaTiO3 as compared to control. The ESR spectra of control and treated BaTiO3 sample showed the g-factor of 2.0; and biofield treatment has substantially changed the width and height of ESR signal in treated BaTiO3 as compared to control. These observations revealed that biofield treatment has significantly altered the crystal structure, lattice strain, and bond vibration of barium titanate.
LEGO prototype of the LineScout robot

description: This report outlines the construction of a replica of the LineScout robot. The LineScout is a remotely operated live‐line inspection and maintenance robot for high‐power electrical transmission lines developed by the Institut de Recherche d'Hydro‐Québec in conjunction with BC‐Hydro. The project sponsor, Dr. Janos Toth of BC‐Hydro, desires a scale model that emulates the basic functions of the LineScout Robot for demonstration purposes. We construct such a replica, primarily using commercially available LEGO construction parts, based on the design done in LEGO Digital Designer by Shawn Crockett over the past summer as part of his co‐op work at BC‐Hydro. The prototype is remotely controlled by an operator, be able to move along a rope or cable, and cross obstacles in its path. The prototype consists of two frames that can translate laterally relative to each other. One frame includes the drive wheels that move the robot along the line, while the other has two grippers that can hold the robot in place when the wheels are not in contact with the line. During an obstacle crossing, the grippers will grip the line on either side of an obstacle, and the wheels will be rotated away from the line, and moved to the other side of the obstacle. The grippers then release to allow the robot to move on. The result performance of the LEGO LineScout is not robust due to the fact that the LEGO pieces deform when under load. An improvement can be seen the most when the wheel frame can be tilted forward more.
Reassessing the human mitochondrial tree: character compatibility analysis of three primate taxa

description: Character compatibility analysis can improve the reliability of phylogenetic inference by removing ‘noisy’ sites in a sequence alignment. Two sites are ‘compatible’ if the same phylogeny can explain their character state distributions across the alignment. Incompatibility indicates homoplasy arising from back or parallel mutation. Sites are assigned compatibility scores proportional to their compatibility with other sites. Iterative removal of low compatibility sites and recalculation of compatibility scores identifies ‘cliques’ of sites that are perfectly inter-compatible. A clique with substantially more sites than all others is likely to indicate a true phylogeny. We evaluated the usefulness of this approach using three primate mitochondrial genome sequence alignments: 128 genomes from the four subspecies of the common chimpanzee, Pan troglodytes; 50 genomes from genera of the gibbon family Hylobatidae; and 87 diverse human (Homo sapiens) genomes. Sites were iteratively removed using the software package 'Shuffle' (Jermiin, Ott & Easteal, unpublished) and MP phylogenies were estimated using the 'ape' and 'phangorn' packages in R. We predicted that for these closely related sequences compatibility analysis would provide greater confidence in well-separated branches and resolve uncertainty about poorly separated branches. As predicted, confidence in the main branches of the P. troglodytes tree, including those separating subspecies, increased; and previously uncertain gibbon lineages were resolved to be consistent with morphological and biogeographical evidence. Analysis of human sequences gave a very different result. Support for the major internal branches that separate deep lineages collapsed, resulting in a ‘star’ phylogeny with all major lineages radiating from a single point. This unexpected result may reflect a relatively high proportion of rare variants in the human population that cause homoplasy at sites with pre-existing variation. We are currently investigating whether the pattern of variation in humans is better explained by population expansion or by directional natural selection.

description: This report describes the design and testing of a camera stabilization system intended for use with on a high altitude balloon. The objective is to be able to control and stabilize a camera with enough precision to obtain clear photos of the stars and other celestial bodies. This report describes several possible mechanical designs but no clearly superior mechanical design emerged during the time allotted to the project. Tests were performed to determine an acceptable level of relative displacement between the camera and its subject. This was determined to be <0.5deg overall and can also be characterized as a rate <0.05/E(t) where E(t) is the shutter speed of the camera. The team constructed and tested a simple stabilization system with a gyroscopic rate sensor, an Arduino microcontroller, and a servo. The system behaviour was determined by PI code written by the team. The team found that this system was not sufficient to provide the stringent level of control required for a stable image. The displacement measured by the team was 5.7deg, which is 10 times higher than that required. Further optimization and design research must be performed before the stability requirements can be met.

description: The stable isotope ratio analysis is widely used in several scientific fields such as agricultural, food authenticity, biochemistry, metabolism, medical research, etc. Resorcinol is one of the most versatile chemicals used for the synthesis of several pharmaceuticals, dyes, polymers, organic compounds, etc. The current research work was designed to investigate the impact of the biofield energy treatment on the isotopic abundance ratios of 13C/12C or 2H/1H or 17O/ 16O (P18O/16O (PM+1/PM ) and M+2/PM ) in resorcinol using Gas chromatograph - mass spectrometry (GC-MS) technique. Resorcinol was divided into two parts - one part was control and another part was considered as biofield energy treated sample. The biofield energy treatment was accomplished through unique biofield energy transmission by Mr. Mahendra Kumar Trivedi (also called as The Trivedi Effect ® ). T1, T2, T3, and T4 were denoted by different time interval analysis of the biofield treated resorcinol in order to understand the influence of the biofield energy treatment on isotopic abundance ratio with respect to the time. The GC-MS spectra of the both control and biofield treated resorcinol exhibited the presence of molecular ion peak [M + ] at m/z 110 (calculated 110.04 for C6H6O2 ) along with major fragmented peaks at m/z 82, 81, 69, 53, and 39. The relative peak intensities of the fragmented ions in biofield treated resorcinol (particularly T2) was significantly changed with respect to the control sample. The stable isotope ratio analysis in resorcinol using GC-MS revealed that the percentage change of the isotopic abundance ratio of PM+1/PM was increased in the biofield treated resorcinol at T1, T2, T3 and T4 by 1.7%, 165.73%, 0.74%, and 6.79%, respectively with respect to the control sample. Consequently, the isotopic abundance ratio of PM+2 /PM in the biofield treated resorcinol at T2, T3, and T4 were enhanced by 170.77%, 3.08%, and 12.31%, respectively with respect to the control sample. Briefly, 13C, 2H, 17O contributions from (C6H6O2 ) + to m/z 111 and 18O contribution from (C6H6O2 ) + to m/z 112 for the biofield treated resorcinol at T2 and T4 were significantly altered as compared to the control sample. For this reasons, biofield treated resorcinol might exhibit altered physicochemical properties like diffusion velocity, mobility and evaporation rate, reaction rate, binding energy, and stability. Biofield treated resorcinol could be valuable in pharmaceutical and chemical industries as intermediates during the preparation of pharmaceuticals and chemical compounds by altering its physicochemical properties, the reaction rate and selectivity, the study of the reaction mechanism and facilitating in designing extremely effective and specific enzyme inhibitors.

How much apocalypse in the apocalypse? On the revelational aspect of apocalyptic concepts in (post-)apocalyptic games

description: In popular fiction, “apocalypse” is typically associated with destruction, doomsday, death, or annihilation. This notion extends to post-apocalyptic settings, which often focus on survival or rebuilding life in a devastated world. Notable examples in gaming include the Fallout series, Frostpunk, The Surge, The Last of Us, and Days Gone.

However, viewing the apocalypse solely as a destructive event and the subsequent survival phase as “post-apocalyptic” oversimplifies the concept. Originally, the term “apocalypse” (from the Greek ἀποκάλυψις, meaning “revelation”) refers to an event that reveals the true nature of something. In religious contexts, it describes a deity revealing itself to humanity, often leading to a transition to a new, perfect world, the process usually accompanied by significant trials, severe battles and suffering. Thus, the apocalyptic concept encompasses both destruction and revelation. However, this processual nature of the apocalyptic event, as well as its revelatory nature, is often completely ignored in games that are labeled as (post-)apocalyptic.

In my talk, I will explore how (post-)apocalyptic games either embrace (e.g., A Plague Tale: Requiem) or overlook (e.g., Fallout 4) this broader understanding of the apocalypse, and where the revelatory nature of the apocalypse takes a more nuanced and differentiated form (e.g., The Last of Us, Part 2). In addition, I will examine how the notion of the “post-apocalyptic” aligns with, but often fails to fully acknowledge, the eschatological framework.

description: Exposome encompasses all environmental factors from conception until old age. Due to the ever changing environment and habits, exposure to environmental contaminants is growing increasingly complex. The HELIX 'early-life exposome' approach involves combining all environmental hazards that mothers and children are exposed to, and linking this to the health, growth and development of the children.

The main objectives of HELIX project include the measurement of a wide range of chemicals and physical environmental hazards in food, consumer products, water, air, noise, and the build environment. Also to define a multi-pattern and individual exposure variability while determining a molecular profile and biological pathways associated with those multiple exposures. To this end, a Bioconductor package has been developed. The package incorporates functions for exploring exposome and its interaction with outcomes, its integration with different omic data as well as downstream analyses to facilitate biological insights though pathway analyses and retrieving data from public databases such as DisGeNET and Comparative Toxicogenomics Database.

The usefulness of the package will be illustrated by analysing data belonging to the HELIX's Spanish cohort where exposome, genome, transcriptome, methylome and proteome data is available joint with information about respiratory and neurocognitive outcomes.

description: The Salisbury University Libraries embarked on a serials and database cancellation project in the 2014-2015 academic year, eventually cutting nearly 20% of journals without causing any faculty protests.  Picking up ideas from numerous other libraries, the three-person project task force developed a three-stage process: 1) preparation—gathering data and laying the groundwork for getting feedback; 2) getting feedback from liaisons, faculty, and departments; and 3) making decisions about what to cut and sharing the results.  This article details the steps taken and key recommendations for other libraries undertaking similar projects.

description: Using SU(3) lattice QCD, we study for the first time the effective potential of the Polyakov loop $\langle P \rangle$ at finite temperature, i.e., the thermodynamic potential, in the field-theoretical way. In the framework of the reweighting method in lattice QCD, we express the effective potential $V_{\rm eff}(\langle P \rangle)$ using the expectation value without a source term. In particular, we consider the most difficult and interesting case of vacuum coexistence at the critical temperature $T_c$. We adopt SU(3) quenched lattice QCD on $48^3 \times 6$ at $β$= 5.89379, which corresponds exactly to the critical temperature $T_c$ of the deconfinement phase transition, and use 200,000 Monte Carlo configurations. After categorizing the gauge configurations into one $Z_3$-symmetric and three $Z_3$-broken vacua each, we perform a vacuum-associated reweighting method, using the gauge configurations around each vacuum separately. Finally, we obtain the Polyakov-loop effective potential, which is well depicted around the $Z_3$-symmetric and $Z_3$-broken vacua.
