description: Categorical quantum mechanics studies quantum theory in the framework of dagger-compact closed categories. Using this framework, we establish a tight relationship between two key quantum theoretical notions: non-locality and complementarity. In particular, we establish a direct connection between Mermin-type non-locality scenarios, which we generalise to an arbitrary number of parties, using systems of arbitrary dimension, and performing arbitrary measurements, and a new stronger notion of complementarity which we introduce here. Our derivation of the fact that strong complementarity is a necessary condition for a Mermin scenario provides a crisp operational interpretation for strong complementarity. We also provide a complete classification of strongly complementary observables for quantum theory, something which has not yet been achieved for ordinary complementarity. Since our main results are expressed in the (diagrammatic) language of dagger-compact categories, they can be applied outside of quantum theory, in any setting which supports the purely algebraic notion of strongly complementary observables. We have therefore introduced a method for discussing non-locality in a wide variety of models in addition to quantum theory. The diagrammatic calculus substantially simplifies (and sometimes even trivialises) many of the derivations, and provides new insights. In particular, the diagrammatic computation of correlations clearly shows how local measurements interact to yield a global overall effect. In other words, we depict non-locality.

description: Crucial for any hypothesis about odor coding is the classification and prediction of sensory qualities in chemical compounds. The relationship between perceptual quality and molecular structure has occupied olfactory scientists throughout the 20th century, but details of the mechanism remain elusive. Odor molecules are typically organic compounds of low molecular weight that may be aliphatic or aromatic, may be saturated or unsaturated, and may have diverse functional polar groups. However, many molecules conforming to these characteristics are odorless. One approach recently used to solve this problem was to apply machine learning strategies to a large set of odors and human classifiers in an attempt to find common and unique chemical features that would predict a chemical’s odor. We use an alternative method that relies more on the biological responses of olfactory sensory neurons and then applies the principles of medicinal chemistry, a technique widely used in drug discovery. We demonstrate the effectiveness of this strategy through a classification for esters, an important odorant for the creation of flavor in wine. Our findings indicate that computational approaches that do not account for biological responses will be plagued by both false positives and false negatives and fail to provide meaningful mechanistic data. However, the two approaches used in tandem could resolve many of the paradoxes in odor perception.

description: We present an implementation of the so-called CKKW-L merging scheme for combining multi-jet tree-level matrix elements with parton showers. The implementation uses the transverse-momentum-ordered shower with interleaved multiple interactions as implemented in PYTHIA8. We validate our procedure using e+e--annihilation into jets and vector boson production in hadronic collisions, with special attention to details in the algorithm which are formally sub-leading in character, but may have visible effects in some observables. We find substantial merging scale dependencies induced by the enforced rapidity ordering in the default PYTHIA8 shower. If this rapidity ordering is removed the merging scale dependence is almost negligible. We then also find that the shower does a surprisingly good job of describing the hardness of multi-jet events, as long as the hardest couple of jets are given by the matrix elements. The effects of using interleaved multiple interactions as compared to more simplistic ways of adding underlying-event effects in vector boson production are shown to be negligible except in a few sensitive observables. To illustrate the generality of our implementation, we also give some example results from di-boson production and pure QCD jet production in hadronic collisions.

description: Although it is assumed that epigenetic mechanisms, such as changes in DNA methylation (DNAm), underlie the relationship between adverse intrauterine conditions and adult metabolic health, evidence from human studies remains scarce. Therefore, we evaluated whether DNAm in whole blood mediated the association between prenatal famine exposure and metabolic health in 422 individuals exposed to famine in utero and 463 (sibling) controls. We implemented a two-step analysis, namely, a genome-wide exploration across 342,596 cytosine-phosphate-guanine dinucleotides (CpGs) for potential mediators of the association between prenatal famine exposure and adult body mass index (BMI), serum triglycerides (TG), or glucose concentrations, which was followed by formal mediation analysis. DNAm mediated the association of prenatal famine exposure with adult BMI and TG but not with glucose. DNAm at PIM3 (cg09349128), a gene involved in energy metabolism, mediated 13.4% [95% confidence interval (CI), 5 to 28%] of the association between famine exposure and BMI. DNAm at six CpGs, including TXNIP (cg19693031), influencing β cell function, and ABCG1 (cg07397296), affecting lipid metabolism, together mediated 80% (95% CI, 38.5 to 100%) of the association between famine exposure and TG. Analyses restricted to those exposed to famine during early gestation identified additional CpGs mediating the relationship with TG near PFKFB3 (glycolysis) and METTL8 (adipogenesis). DNAm at the CpGs involved was associated with gene expression in an external data set and correlated with DNAm levels in fat depots in additional postmortem data. Our data are consistent with the hypothesis that epigenetic mechanisms mediate the influence of transient adverse environmental factors in early life on long-term metabolic health. The specific mechanism awaits elucidation.

description: Within the framework of Becchi-Rouet-Stora-Tyutin (BRST) formalism, we demonstrate the existence of the novel off-shell nilpotent (anti-)dual-BRST symmetries in the context of a six (5 + 1)-dimensional (6D) free Abelian 3-form gauge theory. Under these local and continuous symmetry transformations, the total gauge-fixing term of the Lagrangian density remains invariant. This observation should be contrasted with the off-shell nilpotent (anti-)BRST symmetry transformations, under which, the total kinetic term of the theory remains invariant. The anticommutator of the above nilpotent (anti-)BRST and (anti-)dual-BRST transformations leads to the derivation of a bosonic symmetry in the theory. There exists a discrete symmetry transformation in the theory which provides a thread of connection between the nilpotent (anti-)BRST and (anti-)dual-BRST transformations. This theory is endowed with a ghost-scale symmetry, too. We discuss the algebra of these symmetry transformations and show that the structure of the algebra is reminiscent of the algebra of de Rham cohomological operators of differential geometry.

Detection and characterization of unidirectional molecular rotation
Creators: name: Bloomquist, Casey
Publisher: name: University of British Columbia
Year: 2012

description: The main goal of this work is the detection of the directionality of molecular rotation and the characterization of two experimental approaches to controlling the directionality of molecular rotation with ultrashort pulses. Control of the directionality of molecular rotation is desired in order to learn more about the internal properties of molecular systems as well as for studying and controlling molecular interactions. Further, the techniques for generating unidirectional molecular rotation must be studied to understand the properties of the molecular ensembles that are generated. In order to detect the directionality of molecular rotation, we use circular polarization sensitive resonance-enhanced multiphoton ionization spectroscopy to allow state-selective directionality detection. In this work we explain this technique and demonstrate its ability to measure the directionality of individual rotational states. The two methods for controlling the directionality of molecular rotation are based on the molecular interaction with either a pair of pulses (a “double-kick” scheme) or a larger sequence of pulses (a “chiral pulse train” scheme). In both cases, rotational control is achieved by varying the polarization of and the time delay between consecutive laser pulses. The double-kick and chiral train methods have demonstrated the ability to control the directionality of molecular rotation but have not been extensively studied. In this work, we perform experiments with both the double-kick and chiral train techniques for thorough comparison and characterization of both methods. We show that both methods produce significant rotational directionality. We also demonstrate that increasing the number of excitation pulses enables one to control the sense of molecular rotation and predominately excite a single rotational state, i.e. quantum state selectivity. To further explore the capabilities of both techniques we perform experiments on selectivity in mixtures of spin isomers and molecular isotoplogues. We demonstrate the ability of both techniques to generate counter-rotation of molecular nuclear spin isomers (here, ortho- and para-nitrogen) and molecular isotopologues.

description: Axial vector $(J^{PC}=1^{++})$ charmonium and bottomonium hybrid masses are determined via QCD Laplace sum-rules. Previous sum-rule studies in this channel did not incorporate the dimension-six gluon condensate, which has been shown to be important for $1^{--}$ and $0^{-+}$ heavy quark hybrids. An updated analysis of axial vector charmonium and bottomonium hybrids is presented, including the effects of the dimension-six gluon condensate. The axial vector charmonium and bottomonium hybrid masses are predicted to be 5.13 GeV and 11.32 GeV, respectively. We discuss the implications of this result for the charmonium-like XYZ states and the charmonium hybrid multiplet structure observed in recent lattice calculations.

description: In this paper we examine the impact of India's labor regulations on employment and wages through the lens of the apparel and textiles industry, India’s largest manufacturing employer.  In addition to exploiting cross-state variation in labor regulations, we take advantage of the 2005 abolition of quota restrictions on developing countries’ exports of apparel and textiles products to the developed world and use this as a natural experiment to identify the effects of labor regulations.  Employing a difference-in-difference strategy, we find economically and statistically significant gains in post-2005 employment and wage in the apparel and textiles industry in states that maintained more flexible labor regulations as compared to states with inflexible regulations.  These gains are either absent or muted in the case of labor intensive industries other than apparel and textiles.
Modeling the quantum evolution of the universe through classical matter

description: It is well known that the canonical quantization of the Friedmann-Lemaître-Robertson-Walker (FLRW) filled with a perfect fluid leads to nonsingular universes which, for later times, behave as their classical counterpart. This means that the expectation value of the scale factor $(t)$ never vanishes and, as $t\to\infty$, we recover the classical expression for the scale factor. In this paper, we show that such universes can be reproduced by classical cosmology given that the universe is filled with an exotic matter. In the case of a perfect fluid, we find an implicit equation of state (EoS). We then show that this single fluid with an implict EoS is equivalent to two non-interacting fluids, one of them representing stiff matter with negative energy density. In the case of two non-interacting scalar fields, one of them of the phantom type, we find their potential energy. In both cases we find that quantum mechanics changes completely the configuration of matter for small values of time, by adding a fluid or a scalar field with negative energy density. As time passes, the density of negative energy decreases and we recover the ordinary content of the classical universe. The more the initial wave function of the universe is concentrated around the classical big bang singularity, the more it is necessary to add negative energy, since this type of energy will be responsible for the removal of the classical singularity.

The single-particle tunnel current that flows between the two-dimensional electronic states of the graphene (2D-2D tunneling) is evaluated. At a voltage bias such that the Dirac points of the two electrodes are aligned, a large resonant current peak is produced. The magnitude and width of this peak is computed, and its use for devices is discussed. The influence of both rotational alignment of the graphene electrodes and structural perfection of the graphene is discussed.

Neutral hydrogen optical depth near star-forming galaxies at z~2.4 in the Keck Baryonic Structure Survey

description: [Abridged] We study the interface between galaxies and the intergalactic medium by measuring the absorption by neutral hydrogen in the vicinity of star-forming galaxies at z~2.4. Our sample consists of 679 rest-frame-UV selected galaxies with spectroscopic redshifts that have impact parameters < 2 (proper) Mpc to the line of sight of one of 15 bright, background QSOs. We present the first 2-D maps of the absorption around galaxies, plotting the median Ly-a pixel optical depth as a function of transverse and line of sight, LOS, separation from galaxies. The median optical depth, and hence the median density of atomic hydrogen, drops by more than an order of magnitude around 100 kpc, which is similar to the virial radius of the halos thought to host the galaxies. The median remains enhanced (>3 sigma level) out to at least 2.8 Mpc (i.e. > 9 comoving Mpc). Within 100 (200) kpc, and over \pm 165 km/s, the covering fraction of gas with Ly-a optical depth greater than unity is 100(+0)(-32)% (86(+14)(-18)%). Absorbers with tau(Ly-a)> 0.1 are typically closer to galaxies than random. The mean galaxy overdensity around absorbers increases with the optical depth and also as the length scale over which the galaxy overdensity is evaluated is decreased. Absorbers with tau(Ly-a)~1 reside in regions where the galaxy number density is close to the cosmic mean on scales > 0.25 Mpc. We detect two types of redshift space anisotropies. On scales < 200 km/s, or < 1 Mpc, the absorption is stronger along the LOS than in the transverse direction. This "finger of God" effect may be partly due to redshift errors, but is probably dominated by gas motions within or very close to the halos. On the other hand, on scales of 1.4 - 2.0 Mpc the absorption is compressed along the LOS (>3 sigma significance), which we attribute to large-scale infall (i.e. the Kaiser effect).

17th-century Neapolitan paintings of the Flagellation of Christ : temporality, pain & performance
Creators: name: Vanan, Shalini Mikaela
Publisher: name: University of British Columbia
Year: 2013

description: The Biblical narrative of the Flagellation of Christ persisted in visual representations through the medieval and early modern eras when it was replicated in passion plays, illustrated manuals, sculpture and painting. In 17th-century Naples, several variations on the Flagellation scene were produced by artists such as Michelangelo Merisi da Caravaggio, Giovanni Battista Caracciolo, Jusepe de Ribera, Bernardo Cavallino, Andrea Vaccaro and Luca Giordano. Because it was the first of a series of images, scholars have often viewed Caravaggio’s Flagellation of Christ as the model for all succeeding artists. In this thesis I work against this notion choosing instead to focus on the prevalence of three major themes—temporality, pain and performance—through which to consider the series of paintings as a whole. Using an interdisciplinary approach I address the socio-cultural implications of the practice of flagellation and trace it from its roots as a medieval monastic practice to its widespread prominence in 17th-century Naples. In the examination of three different examples of Neapolitan paintings of the Flagellation of Christ, it becomes apparent that these images suggest violence without overtly displaying it. The implicit corporeal mutilation in the paintings relies primarily on the various accouterments of torture. These devices constitute a visual language that expresses pain through their presence—either implied through gestures, or as props—rather than through the depiction of mortification of the skin. This positions pain in the external world where it is prompts reflection on the performance of flagellation rather than an individual embodied experience. Considering the 17th-century Neapolitan context, I argue that these paintings participated in a dialogue with communal acts of flagellation that can be seen as performances. Using Gilles Deleuze’s notion of ‘becoming’ as a methodological framework, and considering the social practices of Naples and the revivified religious doctrine of the Imitatio Christi, I argue that these paintings, considered as a series, constitute repetitive performances of the same subject through the representation of distinctively different temporal moments.

description: This Note discusses the language state-actors use to create affirmative action programs, and the methods courts employ to determine their constitutionality. It describes the context and history of affirmative action jurisprudence, and explains the anticlassification method, the antisubordination method, and the former’s influence on the current tiered approach.

This Note then discusses a 2016 D.C. Circuit decision, Rothe v. United States Department of Defense, where the court of appeals held that a statutory preference awarded to people “who ha[ve] been subjected to racial or ethnic prejudice” does not contain a racial classification. In so ruling, the court illustrated one reason why the anticlassification approach to affirmative action jurisprudence is untenable. While anticlassification is already an antiquated method of interpretation, this Note contends that, in light of Rothe, it is an unworkable one as well.

description: A geochemical study was undertaken to evaluate whether it was possible to accurately fingerprint Scottish, post-medieval and later red ware pottery sherds. The primary objective was to establish a set of criteria to distinguish between the pottery sherds on both a site and regional basis as an aid to provenancing. These preliminary investigations also utilised the British Geological Survey's national geochemical database of stream sediment analyses as an aid to predicting the potential clay source regions. The results of this study clearly demonstrate the potential power of this combined geochemical and statistical approach, and its application to archaeological site investigations.

description: We provide new values for the model parameters of the covariant constituent quark model (with built--in infrared confinement) in the meson sector by a fit to the leptonic decay constants and a number of electromagnetic decays. We then evaluate, in a parameter free way, the form factors of the $B(B_s)\to P(V)$-transitions in the full kinematical region of momentum transfer. As an application of our results we calculate the widths of the nonleptonic $B_s$-decays into $D_s^- D_s^+,$ $D_s^{\ast\,-} D_s^{+}+D_s^- D_s^{\ast\,+}$ and $D_s^{\ast\,-} D_s^{\ast\,+}$. These modes give the largest contribution to $ΔΓ$ for the $B_s-\bar B_s$ system. We also treat the nonleptonic decay $B_{s}\to\Jpsiϕ$. Although this mode is color suppressed this decay has important implications for the search of possible CP-violating New Physics effects in $B_s-\bar B_s$ mixing.

description: In the wake of repeated police shootings of unarmed Black men and women, police departments across the country are focusing on de-escalation. Yet federal courts reviewing Fourth Amendment excessive force violations are often unwilling to take into account how an officer’s pre-seizure conduct may have affected the need to use force during a civilian encounter. I argue that as part of the Graham v. Connor reasonableness analysis, courts reviewing excessive force claims should consider prior police conduct that impacted the need for force when the officer predictably causes the civilian to respond by employing an overly aggressive tactic. I provide examples of how traditional principles of causation in tort law could apply and provide a workable approach. Moreover, I argue that the severity of the crime provides context that is essential to interpreting causation in the entire chain of events that occurs during the police-civilian interaction.

description: We study the Einstein-Born-Infeld (EBI) theory where the hairy black hole was found as the EBI black hole by using Hod's idea. The hair extends beyond the photon-sphere of the EBI black hole spacetimes. We show that the region beyond the photon-sphere involves more than half of the total hair's mass, which respects Hod's conjectured bound.

Publisher: name: University of Leicester

description: The present study investigates the relationship between vocabulary size and training in vocabulary-learning strategies (VLSs) among preparatory year students at a university in Saudi Arabia. Vocabulary size is important because there is a close association between the size of speakers’ vocabulary and the level of communication they can achieve (Nation, 2001). Sixty male students, twenty each from the humanities, science and health streams, participated in the study and ten students chosen randomly from each group participated in one one-hour long training session on VLSs each day for five consecutive days.The objectives of the study were (i) to discover VLSs that can be utilized by preparatory year students; (ii) to identify the English vocabulary size of the students, and (iii) to examine the effects of VLSs training on the results of vocabulary size tests taken by the students. Data were collected before and after the treatment using a VLSs Questionnaire adapted from Schmitt and McCarthy (1997), consisting of 50 Likert-scale items with a 0.78 reliability coefficient to explore the students’ use of VLSs before and after training. Secondly, XK-Lex (Masrai and Milton, 2012), a word recognition test, was used to measure the students’ vocabulary size before and after training. Thirdly, I used a research diary to record trainees’ expressions of their attitudes to VLSs at the end of each training session. The data were entered into the Statistical Package for Social Sciences (SPSS), version 25.The study found significant differences between the experimental and the control groups’ use of VLSs in the post-treatment, and the differences were positive in favour of the experimental group. When the experimental group was divided into fields of study, there was a statistically significant gain in the participants’ total vocabulary size after training in some fields, suggesting that the VLSs training had had a beneficial effect. The sample size in this field-specific analysis was, however, small and so the findings need to be treated with caution.

title: Mourning, writing, (self-)transformation : the autofiction of Serge Doubrovsky

description: This thesis investigates the capacity of mourning to transform one’s life into writing. Since mourning impacts each individual in a very unique way, its effect in the field of life-writing is incommensurable. In this respect, the changes brought about in the 20th century by the works of Serge Doubrovsky are remarkable: through the exploration of his eight autofictions (word which he coined in 1977) in addition to his six essays on literature, this study demonstrates how his experience of mourning has challenged and redefined the borders of autobiography. This investigation starts with the observation of the writer-narrator’s writing drive, which emerges from a threefold experience of death: the loss of his mother, the trauma of World War II, and the perspective of his own death. The first section argues that writing transforms the private experience of mourning into memory. Since forgetfulness threatens memory, memory must be saved and disseminated; this is why Serge Doubrovsky composes his autofiction as literature which is made of, and which belongs to, memories. The second section observes how mourning transforms the experience of writing and reading: a focus on ‘ressassement’ shows the impact of mourning on writing and how the writer-narrator turns this uncontrollable sign of trauma into his own distinct writing style, called ‘écriture consonnantique’. These transformations participate in the mutation of the writer-reader, fiction-reality, and autobiography-autofiction relationships. The last section observes these abnormal alloys through the lens of the monster. Autofiction could be considered as a monstrous genre, insofar as it recognises the work of the writer to fashion a whole new story out of fragmented and repeated memories in a creative process. Overall, this study assesses Serge Doubrovsky’s ability to challenge existing literary boundaries, and to create, beyond the breach of mourning and within the splits of language, an interdisciplinary work that deeps on renewing literature.

Metals Removed by Outflows from Milky Way Dwarf Spheroidal Galaxies

description: The stars in the dwarf spheroidal satellite galaxies (dSphs) of the Milky Way are significantly more metal-poor than would be expected from a closed box model of chemical evolution. Gas outflows likely carried away most of the metals produced by the dSphs. Based on previous Keck/DEIMOS observations and models, we calculate the mass in Mg, Si, Ca, and Fe expelled from each of eight dSphs. Essentially, these masses are the differences between the observed amount of metals present in the dSphs' stars today and the inferred amount of metals produced by supernovae. We conclude that the dSphs lost 96% to >99% of the metals their stars manufactured. We apply the observed mass function of Milky Way dSphs to the ejected mass function to determine that a single large dSph, like Fornax, lost more metals over 10 Gyr than all smaller dSphs combined. Therefore, small galaxies like dSphs are not significant contributors to the metal content of the intergalactic medium. Finally, we compare our ejected mass function to previous X-ray measurements of the metal content of the winds from the post-starburst dwarf irregular galaxy NGC 1569. Remarkably, the most recent starburst in that galaxy falls exactly on the ejected mass-stellar mass relation defined by the Milky Way dSphs.

Research on marine coastal impacts to promote ecosystem-based management : nonnative species in northeast Pacific estuaries

description: Ecosystem-based management (EBM) offers a holistic evaluation of tradeoffs between human activities, but this offer rests upon a foundation of science. In this thesis, I assessed and advanced the knowledge-base for EBM in five ways, focusing on nonnative species in estuarine ecosystems. In Chapter 2, I tested for the comprehensiveness of research that connects the impacts of anthropogenic activities to changes in ecosystem service production, employing a literature review of estuarine ecosystems. Research on these connections virtually never included the relationship of activities to ecosystem services production, presenting an impressive gap in research for evaluating tradeoffs using EBM. I addressed the sufficiency of existing information regarding nonnative species in eelgrass beds in Chapter 3. I tested the relationship of nonnative species in British Columbia’s (BC) eelgrass beds with arrival pathways and environmental selection factors. There were few (12) nonnatives in BC’s eelgrass; all associated most commonly with aquaculture facilities and warm temperatures. Existing reports included the majority of nonnatives: only one species, the bamboo worm Clymenella torquata, represented a new record, as I described in Chapter 4. Impacts of nonnatives are difficult to limit after invasion. In Chapter 5, I developed an approach for characterizing the potential economic impacts of nonnatives. I focused on European green crab, a nonnative species that has not yet arrived in Puget Sound, Washington. At a range of invasion densities and increasing calorie diets, I calculated a value-at-risk to shellfish harvest ranging from $1.6 - $41 million USD. Such calculations can aid in preparation for impending invasion by motivating prevention and mitigation efforts. Nonnative management is often based on the available understanding of the impacts on native species. In Chapter 6, I assessed available research on the impact of nonnative seagrass, Zostera japonica, in northeast Pacific estuaries. My results suggested existing studies that quantitatively test Z. japonica impacts are insufficient to comprehensively assess the effects of this invasion. My dissertation research highlights the need for research to determine the ecosystem role of nonnatives in their invaded range through analysis of quantitative studies across broad scales.

description: Emerging sonography techniques often require increasing the number of transducer elements involved in the imaging process. Consequently, larger amounts of data must be acquired and processed. The significant growth in the amounts of data affects both machinery size and power consumption. Within the classical sampling framework, state of the art systems reduce processing rates by exploiting the bandpass bandwidth of the detected signals. It has been recently shown, that a much more significant sample-rate reduction may be obtained, by treating ultrasound signals within the Finite Rate of Innovation framework. These ideas follow the spirit of Xampling, which combines classic methods from sampling theory with recent developments in Compressed Sensing. Applying such low-rate sampling schemes to individual transducer elements, which detect energy reflected from biological tissues, is limited by the noisy nature of the signals. This often results in erroneous parameter extraction, bringing forward the need to enhance the SNR of the low-rate samples. In our work, we achieve SNR enhancement, by beamforming the sub-Nyquist samples obtained from multiple elements. We refer to this process as "compressed beamforming". Applying it to cardiac ultrasound data, we successfully image macroscopic perturbations, while achieving a nearly eight-fold reduction in sample-rate, compared to standard techniques.

AMAPOLA: ALMA Polarization Monitoring for Calibrator Sources
Creators: name: Kameno, Seiji
Publisher: name: Zenodo
Year: 2023

description: ALMA has been carrying out a monitoring program for calibrators since its beginning of science operations in 2011. The program covers 46 flux calibrators at Band 3 and Band 7 (or Band 6, complementary) with a cadence of ~10 days. Every observation is performed with a full polarization mode that allows us to measure Stokes parameters. Polarization properties of these calibrators are used for calibration procedure in PI-science polarimetry projects. Using polarized calibrator sources on the sky as a solution to characterize instrumental polarization corrections, we can perform polarization calibration without specific devices installed on the array. Therefore, monitoring Stokes parameters of these calibrators is essential for the ALMA polarization capability. Furthermore, the program reveals time variability of mm/sub-mm polarization that responds to the magnetic fields of AGN jets. In this poster, we present the performance of the polarization monitoring and explain how it works.
