Voters approve measures to ban slavery in four states

Subjects: classificationCode: 48
subject: Law and legal studies

description: On November 8, 2022, the midterm elections were held and there were ballot measures up for vote on the state level. In five states—Alabama, Oregon, Tennessee, Vermont, and Louisiana—voters were asked to decide whether to repeal language from their state constitutions that allow slavery and involuntary servitude as a punishment for crimes.[1] The language in these state constitutions largely resemble that of the Thirteenth Amendment to the United States Constitution which says, “Neither slavery nor involuntary servitude, except as a punishment for crime whereof the party shall have been duly convicted, shall exist within the United States, or any place subject to their jurisdiction.”[2] In Alabama, the measure amends the state constitution to include a provision that states, “No form of slavery shall exist in this state; and there shall not be any involuntary servitude.” In Oregon, the measure “removes all language [in the state constitution] creating an exception and makes the prohibition against slavery and involuntary servitude unequivocal.” In Tennessee, the measure inserts language saying, “slavery and indentured servitude shall be forever prohibited.” In Vermont, the measure removes exceptions and adds a provision that states, “slavery and indentured servitude in any form are prohibited.”[3] The ballot measure was only rejected in one state: Louisiana. State Representative Edmond Jordan, who initially sponsored the measure, urged voters to turn it down because he believed it contained ambiguous language that could inadvertently expand slavery.[4] A new measure will be introduced when lawmakers can produce language that clearly prohibits slavery and involuntary servitude. These ballot measures could serve as a model for repealing the Thirteenth Amendment to the United States Constitution on the federal level and their impact on individuals being held in state prisons may be life changing.
Partially conserved axial current constraints on pion production/absorption within nonrelativistic dynamics

description: We show the necessity of two-nucleon axial currents and associated pion emission/ absorption operators for the partial conservation of the axial current (PCAC) nuclear matrix elements with arbitrary nuclear dynamics described by a nonrelativistic Schroedinger equation. As examples we construct such nonrelativistic axial two-body currents in the linear- and heterotic (g_A = 1.26) sigma models, with an optional isoscalar vector (omega) meson exchange. The nuclear matrix elements obey PCAC only if the nuclear wave functions used in the calculation are solutions to the Schroedinger equation with the static one-meson-exchange potential constructed in the respective (sigma) model. The same holds true for the nucler pion production amplitude, since it is proportional to the divergence of the axial current matrix element, by virtue of PCAC. Thus we found a new consistency condition between the pion creation/absorption operator and the nuclear Hamiltonian. We present examples drawn from our models and discuss implications for one-pion-two-nucleon processes.

description: The leptonic decays of the tau lepton provide relevant tests on the structure of the weak currents and the universality of their couplings to the gauge bosons. The hadronic tau decay modes constitute an ideal tool for studying low--energy effects of the strong interaction in very clean conditions. Accurate determinations of the QCD coupling and the strange quark mass have been obtained with tau decay data. New physics phenomena, such as a non-zero tau neutrino mass or violations of conservation laws can also be searched for with tau decays.

description: Applying mechanical perturbations in a granular assembly may rearrange the configuration of the particles. However, the spatial propagation of an event is not related to the size of the external perturbation alone. Thus, the characteristic length scale of an event is not well defined. In this study, we trigger rearrangements by driving two intruders through a vertical two-dimensional packing of disks. The amplitude of the rearrangements of the granular assembly appearing around the two evolving intruders is related to their separating distances. We show that there exists a characteristic distance between intruders under which the dynamics of the grains above one intruder is influenced by the other. The size of the intruders has little effect on this characteristic length. Finally, we show that the correlation between the movements of the grains decreases with the distance away from the intruders over a larger length scale.
A Nonabelian Yang-Mills Analogue of Classical Electromagnetic Duality

description: The classic question of a nonabelian Yang-Mills analogue to electromagnetic duality is here examined in a minimalist fashion at the strictly 4-dimensional, classical field and point charge level. A generalisation of the abelian Hodge star duality is found which, though not yet known to give dual symmetry, reproduces analogues to many dual properties of the abelian theory. For example, there is a dual potential, but it is a 2-indexed tensor $T_{μν}$ of the Freedman-Townsend type. Though not itself functioning as such, $T_{μν}$ gives rise to a dual parallel transport, $\tilde{A}_μ$, for the phase of the wave function of the colour magnetic charge, this last being a monopole of the Yang-Mills field but a source of the dual field. The standard colour (electric) charge itself is found to be a monopole of $\tilde{A}_μ$. At the same time, the gauge symmetry is found doubled from say $SU(N)$ to $SU(N) \times SU(N)$. A novel feature is that all equations of motion, including the standard Yang-Mills and Wong equations, are here derived from a `universal' principle, namely the Wu-Yang (1976) criterion for monopoles, where interactions arise purely as a consequence of the topological definition of the monopole charge. The technique used is the loop space formulation of Polyakov (1980).

description: We compare the results of the SuSAv2 model including meson-exchange currents (MEC) with the recent measurement of the quasielastic-like double differential antineutrino cross section on hydrocarbon (CH) performed by the MINERvA Collaboration. The relativistic nature of the model makes it suitable to describe these data, which correspond to a mean beam energy of 3.5 GeV. The standard SuSAv2 model predictions agree well with the data without needing any additional or tuned parameter. The role of longitudinal MEC is non-negligible and improves the agreement with the data. We also consider the impact of different treatments of the $Δ$-resonance propagator in the two-body currents on the data comparison.

When A State Wants to Sue the United States

Subjects: classificationCode: 48
subject: Law and legal studies

description: The Supreme Court is set to hear arguments on why several Republican-led states are suing the Biden administration for forgiving student loans, citing that the loan forgiveness program would result in a reduction in their tax revenues. Throughout the majority of American history, there were seldom partisan legal actions initiated by states contesting federal programs. However, this situation shifted when the Supreme Court heard the case of Massachusetts v. EPA. Their decision in 2007 granted states more weight in determining their right to sue, resulting in an increased number of such lawsuits. Additionally, the growing partisan divide among state attorneys general has further accentuated this trend [1].
Relying on this single case, it held that states suing on behalf of the interests of their citizens deserves “special solicitude” when applying a “three-prong test of injury, causation, and redressability” [2]. Essentially, the decision in Massachusetts v. EPA created “special solicitude” for the Attorney General (AG), not merely for states, to litigate independently of other government officials, such as governors. Relaxed standing requirements for states mean fewer hurdles for policy-oriented litigation by the state AGs [3].
But the question remains whether or not states always have the grounds to sue the federal government. In recent years, there has been a noteworthy increase in partisan lawsuits that challenge federal actions, which have embroiled the judiciary in various political disputes and strengthened its authority [4]. These lawsuits are filed over many diverse matters “ranging from fuel emission to transgender rights, from the census to the border wall, from migratory birds to horse racing” [1].
The issue with the three-prong test is its ambiguity and loose framework, which allows states to frequently sue the federal government based on the indirect, downstream effects of federal policies. Despite their belief that President Biden’s program for student loan forgiveness is not legal, two law professors have filed a brief and urged the justices to dismiss the challenge from the states on the grounds of standing.
States ought not to have the exceptional legal authority to initiate lawsuits against the federal executive branch. Instead, they should be held to the same standards as private entities, which would lead to the dismissal of a majority of such lawsuits. Federal courts should not be utilized as open forums to contest policy disagreements between the states and national government [1]. This would serve as a means of diminishing the number of lawsuits, easing the burden on the courts, and preventing them from becoming embroiled in every political dispute related to the federal executive.

description: Tunable electromagnetic sources, such as voltage controlled oscillators (VCO), micro electromechanical systems (MEMS) or diode lasers are often required to be linear during frequency-sweep modulation. In many cases, it might also be sufficient that the degree of the non-linearity can be well controlled. Without further efforts, these conditions are rarely achieved using free running sources. Based on a pre-distortion voltage ramp, we develop in this letter a simple and universal method that minimizes the non-linear frequency response of tunable electromagnetic sources. Using a current-driven Quantum Cascade Laser (QCL) as an example, we demonstrate that the non-linearity can easily be reduced by a factor of ten when using a single distortion parameter $γ$. In the investigation of the IR absorption spectrum of ozone at 10\,$μ$m, an even better reduction of the frequency scale error by two orders of magnitude is obtained by using the pre-distortion method to generate an essentially purely quadratic sweep frequency dependency which can be inverted easily to retrieve precise molecular line positions. After having tested our method on a variety of electromagnetic sources, we anticipate a wide range of applications in a variety of fields.

Evaluation of Constitutive Laws for the Computer Simulation of Fatigue Driven Delamination in Composite Materials
Creators: name: Lopez-Armas, Carlos Alberto
Publisher: name: Imperial College London
Year: 2008

description: A simple mathematical model (cylinder model) is proposed and used to evaluate various constitutive laws used in finite element codes to simulate fatigue-driven delamination in composite materials. The cylinder model has one degree of freedom and allows the evaluation of several parameters of the constitutive laws in an ffcient and accurate way without worrying about the complex interactions that may arise while using a nite element code. This cylinder model enabled a large number of analysis to be performed in a relatively short time and made possible parametric studies with tens of thousands of dfferent sets of parameter values of the constitutive laws. Different fatigue degradations strategies have been implemented into the cylinder model and investigated. A systematic comparison of the different strategies has been performed and it was found that the behaviour of the different strategies is similar but with some variations in the sensitivity to the spacing of the springs and to the size of the increment in the number of loading cycles. The results confirm that the more accurate results are found for smaller values of these two variables. A new fatigue degradation strategy is also proposed. It is based on the construction of a 3-D surface that represents the behaviour of the interface under fatigue loading. This surface has been incorporated into the cylinder model and its performance has been evaluated.

Long-range order, "tower" of states, and symmetry breaking in lattice quantum systems

description: In a quantum many-body system where the Hamiltonian and the order operator do not commute, it often happens that the unique ground state of a finite system exhibits long-range order (LRO) but does not show spontaneous symmetry breaking (SSB). Typical examples include antiferromagnetic quantum spin systems with Neel order, and lattice boson systems which exhibit Bose-Einstein condensation. By extending and improving previous results by Horsch and von der Linden and by Koma and Tasaki, we here develop a fully rigorous and almost complete theory about the relation between LRO and SSB in the ground state of a finite system with continuous symmetry. We show that a ground state with LRO but without SSB is inevitably accompanied by a series of energy eigenstates, known as the "tower" of states, which have extremely low excitation energies. More importantly, we also prove that one gets a physically realistic "ground state" by taking a superposition of these low energy excited states. The present paper is written in a self-contained manner, and does not require any knowledge about the previous works on the subject.

A global workspace framework for combined reasoning
Creators: name: Charnley, John William
Publisher: name: Imperial College London
Year: 2009

description: Artificial Intelligence research has produced many effective techniques for solving a wide range of problems. Practitioners tend to concentrate their efforts in one particular problem solving paradigm and, in the main, AI research describes new methods for solving particular types of problems or improvements in existing approaches. By contrast, much less research has considered how to fruitfully combine different problem solving techniques. Numerous studies have demonstrated how a combination of reasoning approaches can improve the effectiveness of one of those methods. Others have demonstrated how, by using several different reasoning techniques, a system or method can be developed to accomplish a novel task, that none of the individual techniques could perform. Combined reasoning systems, i.e., systems which apply disparate reasoning techniques in concert, can be more than the sum of their parts. In addition, they gain leverage from advances in the individual methods they encompass. However, the benefits of combined reasoning systems are not easily accessible, and systems have been hand-crafted to very specific tasks in certain domains. This approach means those systems often suffer from a lack of clarity of design and are inflexible to extension. In order for the field of combined reasoning to advance, we need to determine best practice and identify effective general approaches. By developing useful frameworks, we can empower researchers to explore the potential of combined reasoning, and AI in general. We present here a framework for developing combined reasoning systems, based upon Baars’ Global Workspace Theory. The architecture describes a collection of processes, embodying individual reasoning techniques, which communicate via a global workspace. We present, also, a software toolkit which allows users to implement systems according to the framework. We describe how, despite the restrictions of the framework, we have used it to create systems to perform a number of combined reasoning tasks. As well as being as effective as previous implementations, the simplicity of the underlying framework means they are structured in a straightforward and comprehensible manner. It also makes the systems easy to extend to new capabilities, which we demonstrate in a number of case studies. Furthermore, the framework and toolkit we describe allow developers to harness the parallel nature of the underlying theory by enabling them to readily convert their implementations into distributed systems. We have experimented with the framework in a number of application domains and, through these applications, we have contributed to constraint satisfaction problem solving and automated theory formation.

Microdroplet reactors for high-throughput chemistry and biology
Creators: name: Srisa-Art, Monpichar
Publisher: name: Imperial College London
Year: 2010

description: Droplet-based microfluidic systems have recently been developed to overcome the problems of slow mixing and dispersion associated with traditional microfluidic systems. By utilising flow instabilities between two immiscible phases, droplets can be generated using normal microfluidic formats. Further, aqueous solutions can be confined and mixed within droplets, resulting in rapid homogenisation and no dispersion. Accordingly, droplet-based microfluidic systems have been utilised in various applications in a high-throughput manner. However, the techniques and methods for droplet formation, manipulation and detection have been continuously studied and improved upon to develop, prepare, manipulate and implement droplet systems for real-world applications. Since droplets can be controllably produced with variable reagent compositions at high generation frequencies (1 kHz or above), on-line detection and characterisation of every high-speed droplet is one of the most important challenges associated with droplet analysis. The ability to extract information from each droplet microreactor is crucial for applications in high-throughput analysis and screening. An appropriate detection technique able to extract the vast amount of information produced in such systems is key in unlocking the full capabilities of droplet-based. In this work, a custom built confocal spectroscopic system was coupled with a droplet-based microfluidic system to conduct high-sensitivity and high-throughput biological experiments. The integration of a confocal system allows for online characterisation of individual droplets in terms of their size, formation frequency, fluorescence intensity and population. The combination of a droplet-based microfluidic system and the confocal detection setup has been successfully used to demonstrate a few high-throughput chemical and biological applications. For example, the droplet system was utilised to demonstrate high-throughput single cell encapsulation, characterisation and quantification for the first time. In addition, highthroughput binding assays and kinetic measurements using a well-known streptavidin-biotin binding model and a protein-protein interaction were performed. Furthermore, a novel approach for fluorescence lifetime imaging (FLIM) was developed and used to analyse mixing patterns within droplets. Specifically, data from FLIM measurements were extracted to determine spatially localised fluorescence lifetimes within droplets and thus a twodimensional map of droplet mixing. Finally, the droplet-based microfluidic approach was exploited to perform biological analysis at the single molecule level.

description: The universal Teichmüller space is an infinitely dimensional generalization of the classical Teichmüller space of Riemann surfaces. It carries a natural Hilbert structure, on which one can define a natural Riemannian metric, the Weil-Petersson metric. In this paper we investigate the Weil-Petersson Riemannian curvature operator $\tilde{Q}$ of the universal Teichmüller space with the Hilbert structure, and prove the following: (i) $\tilde{Q}$ is non-positive definite. (ii) $\tilde{Q}$ is a bounded operator. (iii) $\tilde{Q}$ is not compact; the set of the spectra of $\tilde{Q}$ is not discrete. As an application, we show that neither the Quaternionic hyperbolic space nor the Cayley plane can be totally geodesically immersed in the universal Teichmüller space endowed with the Weil-Petersson metric.

Investigation of genetics and genomics in asthma

Publisher: name: Imperial College London

description: Asthma is the most common disease of childhood in the westernised world, affecting one child in seven in the United Kingdom alone. It is a complex disease involving both genetic and environmental factors. The financial burden for sufferers approximates £1 billion per annum in the UK and 80% of the sum is attributable to the patients with the severe, “difficult/therapy-resistant” form of the disease. Previously, a Genome Wide Association Study (GWAS) for childhood asthma identified a number of loci significantly associated to the disease. The top ten SNP hits with the highest association (0.0001>P>0.00001) were chosen for an investigation of their importance in cases of severe asthma, both childhood and adult. The 10 SNPs were genotyped in 397 adults and 94 children using TaqMan® SNP Genotyping Assays. Genotyping data was analysed for genetic associations to the severe asthma phenotype using chi-squared tests. Control data was obtained from data generated in the original GWAS for the British controls. SNP rs6585018 located in the PDCD4 gene predicted promoter was found to be significantly associated to childhood asthma (P=3.4x10-7). Additional markers on the PDCD4 gene area were chosen to be typed in 116 severe asthmatic children and 145 healthy children from the UK. SNPs rs6585018 (P=0.005), rs1322997 (P=0.005) in the predicted promoter area and rs34104444 (P=0.01) in exon 5 were associated to severe asthma. The three SNPs were also correlated with PDCD4 transcript levels. PDCD4 genomic area was analysed in silico and ElectroMobility Shift Assay (EMSA) experiments were designed for the rs6548018 alleles to examine how they alter transcription factor binding sites. SNP rs6585018 was found to alter the binding site of the Myb transcription factor possibly altering the expression of PDCD4 gene. This study has provided insights into the genetic factors that are involved in disease aetiology of severe asthma.
Analogue circuits for low power communication
Creators: name: Tuckwell, Mark David
Publisher: name: Imperial College London
Year: 2010

description: Low power electronic circuits are required to extend the operational time of battery operated devices. They are also necessary to reduce the power consumption of equipment in general, especially as the world tries to cut energy usage. The first section of this thesis explores fundamental and implementation limits for low power circuits. The energy requirements of amplification are presented and a lower bound on the energy required to transmit information over a point to point link is proposed. It is evident from the low power limits survey that when a transistor is biased, significant thermodynamic energy is required to reduce the resistance of the channel. A transmitter is presented that turns on a transistor for 0.1 % of transmitted time. This transmitter approximates a Gaussian pulse by allowing the impulse response of two 2nd order transmitting elements to sum in free space. The transmitter is of low complexity and the receiver architecture ensures that no on-line tuning is required. Measured results indicate that by using coherent detection a 1 Mbps, 50 mm distance link with a bit error rate of 10−3 can be achieved. The bandwidth of the transmitted pulse is 30-37.5 MHz and 30 dB of out of band attenuation is provided. An analogue Gabor transform is described which splits a signal into parallel paths of a lower bandwidth. This enables post processing at lower clock rates, which can reduce energy dissipation. An implementation of the transform using sub-threshold CMOS continuous time filters is presented. A novel method for designing low power gmC filters using simple models of identical transconductors is used to specify transistor sizes. Measured results show that the transform consumes 7 μW for an input signal bandwidth of 4 kHz.

We find the magnetic correlation energy of the system can be significantly improved when an orbital order of the d-wave form is spontaneously generated. On the other hand, the magnetic correlation energy increases as one introduce either an on-site or an extended s-wave orbital order. More specifically, we find that the on-site orbital order is disfavored by the Hund's rule coupling and the extended s-wave orbital order is disfavored by the stripy magnetic correlation pattern in the IBSs.

description: The structure of block-spin embeddings of the U(1) lattice current algebra is described. For an odd number of lattice sites, the inner realizations of the shift automorphism areclassified. We present a particular inner shift operator which admits a factorization involving quantum dilogarithms analogous to the results of Faddeev and Volkov.

description: One of the main challenges for polarimetric observations of active galactic nuclei (AGN) is to properly estimate the amount of parasitic light that contaminates the polarization signal. Removing this unpolarized flux is a complex task that has only been achieved in a couple of objects. In this fifth paper of the series, we present a new version of the Monte Carlo code STOKES that accounts for dilution by interstellar polarization and host starlight in radiative transfer modeling. We upgrade our code by including spectral energy distribution (SED) templates for a set of representative host galaxies. The unpolarized light emitted by those hosts alters the observer polarization while being coherently radiatively coupled to the AGN structure. We also include in our analysis tool a routine that may add, depending on the user's objectives, an interstellar component. Using a generic AGN model, we illustrate how interstellar polarization and starlight dilution impact the observed polarimetric signal of AGN. We apply our code to NGC-1068, an archetypal edge-on AGN and demonstrate that STOKES can reproduce its SED, the expected wavelength-dependent polarimetric signatures, and the observed high-angular resolution polarimetric maps. Using the flexibility of the code, we derive several intrinsic parameters such as the system inclination and the torus opening angle. The new version of our publicly available code now allows observers to better prepare their observations, interpret their data and simulate the three-dimensional geometry and physics of AGN in order to probe unresolved structures. Additionally, the radiative interaction between the host and the AGN can be used to probe the co-evolution of the system.

description: A new operator for pion photo- and electroproduction has been developed for nuclear applications at photon equivalent energies up to 1 GeV. The model contains Born terms, vector mesons and nucleon resonances ($P_{33}(1232)$, $P_{11}(1440)$, $D_{13}(1520)$, $S_{11}(1535)$, $F_{15}(1680)$, and $D_{33}(1700)$). The resonance contributions are included taking into account unitarity to provide the correct phases of the pion photoproduction multipoles. The $Q^2$ dependence of electromagnetic resonance vertices is described with appropriate form factors in the electromagnetic helicity amplitudes. Within this model we have obtained good agreement with the experimental data for pion photo- and electroproduction on the nucleon for both differential cross sections and polarization observables. The model can be used as a starting point to predict and analyze forthcoming data.

description: Surprisingly little is known about how mammal vocal signals are used to achieve behavioural synchrony in the lead up to copulation. The ability to signal short-term fluctuations in arousal levels and behavioural intention is likely to be particularly important for synchronizing mating behaviour in asocial species, which must overcome their natural avoidance and aggressive tendencies to mate. Here, we examined vocal behaviour during breeding encounters in captive giant pandas (Ailuropoda melanoleuca) to gain a greater understanding of how close-range vocal signalling mediates reproduction in this asocial, and conservation-dependent species. Our results revealed that the occurrence of different giant panda vocalizations and acoustic variation within these calls is predictive of successful encounters leading to copulation, as opposed to unsuccessful encounters that do not. In addition, key differences were detected between vocalizations produced during and just prior to copulation. These findings illustrate that vocal exchanges are crucial for achieving behavioural synchrony and signalling intention to mate in giant pandas, and could also provide a valuable tool for breeding programmes, helping conservation managers to assess the likelihood of breeding introductions leading to copulation or potentially injurious failure.

Many-body effects in twisted bilayer graphene at low twist angles

description: We study the zero-temperature many-body properties of twisted bilayer graphene with a twist angle equal to the so-called `first magic angle'. The system low-energy single-electron spectrum consists of four (eight, if spin label is accounted) weakly-dispersing partially degenerate bands, each band accommodating one electron per Moir{é} cell per spin projection. This weak dispersion makes electrons particularly susceptible to the effects of interactions. Introducing several excitonic order parameters with spin-density-wave-like structure, we demonstrate that (i)~the band degeneracy is partially lifted by the interaction, and (ii)~the details of the low-energy spectrum becomes doping-dependent. For example, at or near the undoped state, interactions separate the eight bands into two quartets (one quartet is almost filled, the other is almost empty), while for two electrons per Moiré cell, the quartets are pulled apart, and doublets emerge. When the doping is equal to one or three electrons per cell, the doublets split into singlets. Hole doping produces similar effects. As a result, electronic properties (e.g., the density of states at the Fermi energy) demonstrate oscillating dependence on the doping concentration. This allows us to reproduce qualitatively the behavior of the conductance observed recently in experiments [Cao et al., Nature {\bf 556}, 80 (2018)]. Near half-filling, the electronic spectrum loses hexagonal symmetry indicating the appearance of a many-body nematic state.
