description: We propose a novel a posteriori error assessment for the single-reference coupled-cluster (SRCC) method called the $S$-diagnostic. We provide a derivation of the $S$-diagnostic that is rooted in the mathematical analysis of different SRCC variants. We numerically scrutinized the $S$-diagnostic, testing its performance for (1) geometry optimizations, (2) electronic correlation simulations of systems with varying numerical difficulty, and (3) the square-planar copper complexes [CuCl$_4$]$^{2-}$, [Cu(NH$_3$)$_4$]$^{2+}$, and [Cu(H$_2$O)$_4$]$^{2+}$. Throughout the numerical investigations, the $S$-diagnostic is compared to other SRCC diagnostic procedures, that is, the $T_1$, $D_1$, and $D_2$ diagnostics as well as different indices of multi-determinantal and multi-reference character in coupled-cluster theory. Our numerical investigations show that the $S$-diagnostic outperforms the $T_1$, $D_1$, and $D_2$ diagnostics and is comparable to the indices of multi-determinantal and multi-reference character in coupled-cluster theory in their individual fields of applicability. The experiments investigating the performance of the $S$-diagnostic for geometry optimizations using SRCC reveal that the $S$-diagnostic correlates well with different error measures at a high level of statistical relevance. The experiments investigating the performance of the $S$-diagnostic for electronic correlation simulations show that the $S$-diagnostic correctly predicts strong multi-reference regimes. The $S$-diagnostic moreover correctly detects the successful SRCC computations for [CuCl$_4$]$^{2-}$, [Cu(NH$_3$)$_4$]$^{2+}$, and [Cu(H$_2$O)$_4$]$^{2+}$, which have been known to be misdiagnosed by $T_1$ and $D_1$ diagnostics in the past. This shows that the $S$-diagnostic is a promising candidate for an a posteriori diagnostic for SRCC calculations.

Time and Inhibitory Learning

Subjects: subject: Psychology
subject: FOS: Psychology

description: Associative theories of learning state that an organism acquires new behaviors when associations are formed between a Conditioned Stimulus (CS) and an Unconditioned Stimulus (US). Alternative theories suggest that learning is not reliant on associations between stimuli, but rather on the temporal information conveyed by stimuli. Studies have shown that temporal information influences Excitatory Learning. However, little is known about how time affects Inhibitory Learning, or the learning that occurs during periods of nonreinforcement. In two experiments, rats were exposed to auditory tones of varying durations, receiving appetitive reinforcers solely in the absence of the tones. The first experiment examined the effect of fixed CS- durations on inhibitory responding, while the second examined the effect of variable CS- durations on inhibitory responding. Results show that responding was dependent on the duration of the auditory CS-, as well as whether or not the CS- was of a fixed or variable duration, indicating that time influences inhibitory learning.

description: An inquiry into G.K. Chesterton's use of heroic imagery to conceptualize World War I. Tracing the impact of Chesterton's poetry and novels upon war poets like Joyce Kilmer, this English department senior essay complicates the narrative of Paul Fussell's "The Great War and Modern Memory." While the First World War did prove a watershed moment in English poetry, producing a famous literature of "disenchantment," an alternative tradition of heroic mythology retained vitality even in literary modernism.

description: A scattering process can be described by suitably closing the system and considering the first return map from the entrance onto itself. This scattering map may be singular and discontinuous, but it will be measure preserving as a consequence of the recurrence theorem applied to any region of a simpler map. In the case of a billiard this is the Birkhoff map. The semiclassical quantization of the Birkhoff map can be subdivided into an entrance and a repeller. The construction of a scattering operator then follows in exact analogy to the classical process. Generically, the approximate unitarity of the semiclassical Birkhoff map is inherited by the S-matrix, even for highly resonant scattering where direct quantization of the scattering map breaks down.

description: The use of the non-linear SPDEs are inevitable in both physics and applied mathematics since many of the physical phenomena in nature can be effectively modeled in random and non-linear way. The Kardar-Parisi-Zhang (KPZ) equation is well-known for its applications in describing various statistical mechanical models including randomly growing surfaces, directed polymers and interacting particle systems. We consider the upper and lower tail probabilities for the centered (by time$/24$) and scaled (according to KPZ time$^{1/3}$ scaling) one-point distribution of the Cole-Hopf solution of the KPZ equation. We provide the first tight bounds on the lower tail probability of the one point distribution of the KPZ equation with narrow wedge initial data. Our bounds hold for all sufficiently large times $T$ and demonstrates a crossover between super-exponential decay with exponent $\tfrac{5}{2}$ (and leading pre-factor $\frac{4}{15\pi} T^{1/3}$) for tail depth greater than $T^{2/3}$ (deep tail), and exponent $3$ (with leading pre-factor at least $\frac{1}{12}$) for tail depth less than $T^{2/3}$ (shallow tail). We also consider the case when the initial data is drawn from a very general class. For the lower tail, we prove an upper bound which demonstrates a crossover from super-exponential decay with exponent $3$ in the shallow tail to an exponent $\frac{5}{2}$ in the deep tail. For the upper tail, we prove super-exponential decay bounds with exponent $\frac{3}{2}$ at all depths in the tail. We study the correlation of fluctuations of the narrow wedge solution to the KPZ equation at two different times. We show that when the times are close to each other, the correlation approaches one at a power-law rate with exponent $\frac{2}{3}$, while when the two times are remote from each other, the correlation tends to zero at a power-law rate with exponent $-\frac{1}{3}$.

A point-like particle detector traveling on a timelike geodesic in a Misner space with this vacuum detects nothing. Misner space with this vacuum thus creates no problems for time travel in and of itself but a time traveler may pose a danger to himself and to the spacetime.

An examination of the syntactic and semantic characteristics of Shang and Xia in Mandarin

Year: 1989
Subjects: subject: Mandarin dialects Syntax
subject: Mandarin dialects Semantics

description: This thesis examines some of the major aspects of the semantic and syntactic characteristics of 'shang' and 'xia' in Mandarin Chinese. One of their basic meanings relates to the vertical dimension, both 'shang' and 'xia, being involved in the indication of vertical direction and position. It is seen that this vertical dimension can extend into the realms of quantity, status, sequencing and time. The use of vertical terms in these extended areas is found in other languages, such as English, suggesting that there may some perceptual, cognitive and/or experiential bases for such extensions. The very productive use of 'shai1g' and 'xia' in sequencing and time in Mandarin is noted and it is suggested that this may be related to the importance of hierarchical relations Chinese culture. The grammatical functions of 'shang' and 'xia' are also examined. As verb complements the two morphemes are involved in marking perfectivity. This seems to be due as much to the fact that they are directionals, thus involving concepts such as goal and source, as to their specific vertical meanings. Comparisons are made with the use of spatial terms as aspectual markers in other languages. The role of 'shang' and 'xia' as place word markers is also considered. TI1e thesis looks at the grammatical status of 'shang' and 'xia', and notes the relationship between this and their inherent semantic meanings. 'Shang' is identified as the unmarked member of the pair and is also the morpheme which, when acting as a localiser, appears to have gone further along the path from lexical to grammatical material since in some cases it see·ms to have little semantic content and just serves a grammatical function.
Israel coordinates for all static spherically symmetric spacetimes with vanishing second Ricci invariant

description: Static spherically symmetric spacetimes with vanishing second Ricci invariant constitute an important class of solutions to Einstein's equations and more generally as archetypes of regular black holes. When studying completeness one is most often presented with the Kruskal - Szekeres procedure. However, this procedure only works if the spacetime admits a single non-degenerate Killing horizon (a single bifurcation two-sphere). Here we generalize the Israel procedure to examine a constructive approach to completeness based entirely on the static spherically symmetric nature of spacetimes with a vanishing second Ricci invariant. It is shown by "block gluing" that the Israel procedure can cover two bifurcation two-spheres, but can fail with three. No coordinate transformations are used in this work.

description: We consider a quantum limit-cycle oscillator implemented in a spin system whose quantization axis is slowly rotated. Using a kinematic approach to define geometric phases in nonunitary evolution, we show that the quantum limit-cycle oscillator attains a geometric phase when the rotation is sufficiently slow. In the presence of an external signal, the geometric phase as a function of the signal strength and the detuning between the signal and the natural frequency of oscillation shows a structure that is strikingly similar to the Arnold tongue of synchronization. Surprisingly, this structure vanishes together with the Arnold tongue when the system is in a parameter regime of synchronization blockade. We derive an analytic expression for the geometric phase of this system, valid in the limit of slow rotation of the quantization axis and weak external signal strength, and we provide an intuitive interpretation for this surprising effect.

description: Fault detection has a long tradition: the necessity to provide the most accurate diagnosis possible for a process plant criticality is somehow intrinsic in its functioning. Continuous monitoring is a possible way for early detection. However, it is somehow fundamental to be able to actually simulate failures. Reproducing the issues remotely allows to quantify in advance their consequences, causing literally no real damage. Within this context, signed directed graphs have played an essential role within the years, managing to model with a relatively simple theory diverse elements of an industrial network, as well as the logic relations between them.\\ In this work we present a quantitative approach, employing directed graphs to the simulation and automatic reconfiguration of a fault in a network. To model the typical operation of industrial plants, we propose several additions with respect to the standard graphs: 1. a quantitative measure to control the overall residual capacity, 2. nodes of different categories - and then different behaviors - and 3. a fault propagation procedure based on the predecessors and the redundancy of the system. The obtained graph is able to mimic the behaviour of the real target plant when one or more faults occur. Additionally, we also implement a generative approach capable to activate a particular category of nodes in order to contain the issue propagation, equipping the network with the capability of reconfigure itself and resulting then in a mathematical tool useful not only for simulating and monitoring, but also to design and optimize complex plants. The final asset of the system is provided in output with its complete diagnostics, and a detailed description of the steps that have been carried out to obtain the final realization.
Location of the innermost stable circular orbit of binary neutron stars in the post Newtonian approximations of general relativity

description: In this paper, we present results obtained from our recent studies on the location of the innermost stable circular orbit (ISCO) for binary neutron stars (BNSs) in several levels of post Newtonian (PN) approximations. We reach the following conclusion at present: (1) even in the Newtonian case, there exists the ISCO for binary of sufficiently stiff equation of state (EOS). If the mass and the radius of each star are fixed, the angular velocity at the ISCO $Ω_{ISCO}$ is larger for softer EOS: (2) when we include the first PN correction, there appear roughly two kinds of effects. One is the effect to the self-gravity of each star of binary and the other is to the gravity acting between two stars. Due to the former one, each star of binary becomes compact and the tidal effect is less effective. As a result, $Ω_{ISCO}$ tends to be increased. On the other hand, the latter one has the property to destabilize the binary orbit, and $Ω_{ISCO}$ tends to be decreased. If we take into account both effects, however, the former effect is stronger than the latter one, and $Ω_{ISCO}$ becomes large with increase of the 1PN correction: (3) the feature mentioned above is more remarkable for softer EOS if the mass and radius are fixed. This is because for softer EOS, each star has the larger central density and is susceptible to the GR correction: (4) there has been no self consistent calculation including all the 2PN effects and only exist studies in which one merely includes the effect of the 2PN gravity acting between two stars. In this case, the effect has the property to destabilize the binary orbit, so that $Ω_{ISCO}$ is always smaller than that for the Newtonian case. If we include the PN effect of the self-gravity to each star, $Ω_{ISCO}$ will increase.

description: We describe a method to create and store scalable and long-lived entangled spin-squeezed states within a manifold of many-body cavity dark states using collective emission of light from multilevel atoms inside an optical cavity. We show that the system can be tuned to generate squeezing in a dark state where it will be immune to superradiance. We also show more generically that squeezing can be generated using a combination of superradiance and coherent driving in a bright state, and subsequently be transferred via single-particle rotations to a dark state where squeezing can be stored. Our findings, readily testable in current optical cavity experiments with alkaline-earth-like atoms, can open a path for dissipative generation and storage of metrologically useful states in optical transitions.

description: How do the brain and the immune system interact, and what are the consequences of this interaction on the physiology of an organism during infection? The main focus of my thesis is neuroimmune interaction, as studied in the following: (1) circadian regulation of immune system function, specifically phagocytosis by immune cells during bacterial infection; (2) the impact of circadian-regulated metabolism and feeding behavior on immunity and host tolerance of bacterial infection; and (3) immune system function in the context of Fragile X syndrome, a neurological disease known to cause circadian dysregulation. To investigate the interactions between these complex physiologies, I use the well-characterized and genetically tractable Drosophila melanogaster animal model.  Each topic is briefly introduced in Chapter 1.  Chapter 2 focuses on the body of work identifying the circadian regulation of the immune system, particularly phagocytosis, by immune cells during bacterial infection.  Chapter 3 highlights findings regarding how diet and host metabolic state impact survival after infection.  Chapter 4 illustrates phagocytic immune cell defects both systemically and in the brain in the Drosophila model of Fragile X syndrome. Lastly the conclusions discuss how these three works have built on our fund of knowledge of neuroimmune interactions and the future implications for these results.

The model is described by a dynamical spinor superfield and an auxiliary chiral scalar superfield. On-shell this model leads to a spin-1/2, spin-3/2 and two spin-1 propagating component fields. The superfield action is given and its structure in the fermionic component sector is presented. We prove that the most general theory is characterized by a one parameter family of actions. The massless limit is shown to correspond to the dynamics of both the gravitino and superhelicity-1/2 multiplets.

description: The widespread availability of internet access and handheld devices confers to social media a power similar to the one newspapers used to have. People seek affordable information on social media and can reach it within seconds. Yet this convenience comes with dangers; any user may freely post whatever they please and the content can stay online for a long period, regardless of its truthfulness. A need to detect untruthful information, also known as fake news, arises. In this paper, we present an end-to-end solution that accurately detects fake news and immunizes network nodes that spread them in real-time. To detect fake news, we propose two new stack deep learning architectures that utilize convolutional and bidirectional LSTM layers. To mitigate the spread of fake news, we propose a real-time network-aware strategy that (1) constructs a minimum-cost weighted directed spanning tree for a detected node, and (2) immunizes nodes in that tree by scoring their harmfulness using a novel ranking function. We demonstrate the effectiveness of our solution on five real-world datasets.

description: Motivated by the holographic complexity proposals, in this paper, we investigate the time dependence of the complexity for the Fermionic thermofield double state (TFD) using the Nielsen approach and Fubini-Study (FS) approach separately. In both two approaches, we discuss the results for different reference states: the Dirac vacuum state and the Gaussian state which has no spatial entanglement (NSE). For Dirac vacuum reference state, we find that the complexity by both two approaches is time independent and the circuit complexity shares the same expression for both methods with the $L^2$ norm. For the NSE reference state, the complexity by the Nielsen approach is time-dependent while it by the FS approach is time-independent. Further, we find our dynamical results are in good agreement with the bosonic case, where the complexity evolves in time and saturates after a time at the order of the inverse temperature. And we show that the complexity of formation is also shared same similar behaviors with the holographic complexity.

description: This paper combines experimental and modelling studies to provide a detailed examination of the influence of porosity volume fraction and morphology on the polarisation-electric field response of ferroelectric materials. The broadening of the electric field distribution and a decrease in the electric field experienced by the ferroelectric ceramic medium due to the presence of low-permittivity pores is examined and its implications on the shape of the hysteresis loop, remnant polarisation and coercive field is discussed. The variation of coercive field with porosity level is seen to be complex and is attributed to two competing mechanisms where at high porosity levels the influence of the broadening of the electric field distribution dominates, while at low porosity levels an increase in the compliance of the matrix is more important. This new approach to understanding these materials enables the seemingly conflicting observations in the existing literature to be clarified and provides an effective approach to interpret the influence of pore fraction and morphology on the polarisation behaviour of ferroelectrics. Such information provides new insights in the interpretation of the physical properties of porous ferroelectric materials to inform future effort in the design of ferroelectric materials for piezoelectric sensor, actuator, energy harvesting, and transducer applications.

description: Modern radio astronomy instruments generate vast amounts of data, and the increasingly challenging radio frequency interference (RFI) environment necessitates ever-more sophisticated RFI rejection algorithms. The "needle in a haystack" nature of searches for transients and technosignatures requires us to develop methods that can determine whether a signal of interest has unique properties, or is a part of some larger set of pernicious RFI. In the past, this vetting has required onerous manual inspection of very large numbers of signals. In this paper we present a fast and modular deep learning algorithm to search for lookalike signals of interest in radio spectrogram data. First, we trained a B-Variational Autoencoder on signals returned by an energy detection algorithm. We then adapted a positional embedding layer from classical Transformer architecture to a embed additional metadata, which we demonstrate using a frequency-based embedding. Next we used the encoder component of the B-Variational Autoencoder to extract features from small (~ 715,Hz, with a resolution of 2.79Hz per frequency bin) windows in the radio spectrogram. We used our algorithm to conduct a search for a given query (encoded signal of interest) on a set of signals (encoded features of searched items) to produce the top candidates with similar features. We successfully demonstrate that the algorithm retrieves signals with similar appearance, given only the original radio spectrogram data. This algorithm can be used to improve the efficiency of vetting signals of interest in technosignature searches, but could also be applied to a wider variety of searches for "lookalike" signals in large astronomical datasets.

description: Scattering on the energy shell is viewed here as the relation between the bound states of the Hamiltonian, restricted to sections on leads that are asymptotically independent, far away from the interaction region. The decomposition is achieved by sectioning this region and adding new leads, thus generating two new scatterers. So a resonant scatterer, whose $\bS$-matrix has sharp energy peaks, can be resolved into a pair of scatterers with smooth energy dependence. The resonant behaviour is concentrated in a spectral determinant obtained from a dissipative section map. The semiclassical limit of this theory coincides with the orbit resummation previously proposed by Georgeot and Prange. A numerical example for a semiseparable scatterer is investigated, revealing the accurate portrayal of the Wigner time delay by the spectral determinant.

description: We investigate the ground-state phase diagram of the frustrated transverse field Ising (TFI) model on the checkerboard lattice (CL), which consists of Néel, collinear, quantum paramagnet and plaquette-valence bond solid (VBS) phases. We implement a numerical simulation that is based on the recently developed unconstrained tree tensor network (TTN) ansatz, which systematically improves the accuracy over the conventional methods as it exploits the internal gauge selections. At the highly frustrated region ($J_2=J_1$), we observe a second order phase transition from plaquette-VBS state to paramagnet phase at the critical magnetic field, $Γ_{c}=0.28$, with the associated critical exponents $ν=1$ and $γ\simeq0.4$, which are obtained within the finite size scaling analysis on different lattice sizes $N=4\times 4, 6\times 6, 8\times8$. The stability of plaquette-VBS phase at low magnetic fields is examined by spin-spin correlation function, which verifies the presence of plaquette-VBS at $J_2=J_1$ and rules out the existence of a Néel phase. In addition, our numerical results suggest that the transition from Néel (for $J_2

description: It is argued that (a) In the quantum realm test-particle masses have non-trivial observability which induces a non-geometric element in gravity, (b) Any theory of quantum gravity, on fundamental grounds, must contain an element of non-locality that makes position measurements non-commutative, and (c) The classical notion of free fall does not readily generalize to the quantum regime.

description: Single-particle reconstruction technique is one of the major approaches to studying ribosome structure and membrane proteins. In this thesis, I report the use of time-resolved cryo-EM technique to study the structure of short-lived ribosome complexes and conventional cryo-EM technique to study the structure of ribosome complexes and membrane proteins. The thesis consists three parts.
      The first part is the development of time-resolved cryo-EM technique. I document the protocol for how to capture short-lived states of the molecules with time-resolved cryo-EM technique using microfluidic chip. Working closely with Dr. Lin’s lab at Columbia University Engineering Department, I designed and tested a well-controlled and effective microspraying-plunging method to prepare cryo-grids. I demonstrated the performance of this device by a 3-Å reconstruction from about 4000 particles collected on grids sprayed with apoferritin suspension.
      The second part is the application of time-resolved cryo-EM technique for studying short-lived ribosome complexes in bacteria translation processes on the time-scale of 10-1000 ms. I document three applications on bacterial translation processes.  The initiation project is collaborated with Dr. Gonzalez’s lab at Chemistry Department, Columbia University. The termination and recycling projects are collaborated with Dr. Ehrenberg’s lab at Department of Cell and Molecular Biology, Uppsala University. I captured and solved short-lived ribosome intermediates complexes in these processes. The results demonstrate the power of time-resolved cryo-EM to determine how a time-ordered series of conformational changes contribute to the mechanism and regulation of one of the most fundamental processes in biology.
      The last part is the application of conventional cryo-EM technique to study ribosome complexes and membrane proteins. This part includes five collaboration projects.
      Human GABA(B) receptor project is the collaboration with Dr. Fan at Department of Pharmacology, Columbia University. Cyclic nucleotide-gated (CNG) channels project is the collaboration with Dr. Yang at Department of Biological Sciences, Columbia University.
      The cryo-EM study of Ybit-70S ribosome complex and Cystic fibrosis transmembrane conductance regulator (CFTR) project are the collaboration with Dr. Hunt at Department of Biological Sciences, Columbia University. The cryo-EM study of native lipid bilayer in membrane protein transporter is the collaboration with Dr. Hendrickson at Department of Biochemistry and Molecular Biophysics, Columbia University and Dr. Guo at Department of Medicinal Chemistry, Virginia Commonwealth University.

description: Murine rodents generate ultrasonic vocalizations (USVs) with frequencies that extend to around 120kHz. These calls are important in social behaviour, and so their analysis can provide insights into the function of vocal communication, and its dysfunction. The manual identification of USVs, and subsequent classification into different subcategories is time consuming. Although machine learning approaches for identification and classification can lead to enormous efficiency gains, the time and effort required to generate training data can be high, and the accuracy of current approaches can be problematic. Here we compare the detection and classification performance of a trained human against two convolutional neural networks (CNNs), DeepSqueak and VocalMat, on audio containing rat USVs. Furthermore, we test the effect of inserting synthetic USVs into the training data of the VocalMat CNN as a means of reducing the workload associated with generating a training set. Our results indicate that VocalMat outperformed the DeepSqueak CNN on measures of call identification, and classification. Additionally, we found that the augmentation of training data with synthetic images resulted in a further improvement in accuracy, such that it was sufficiently close to human performance to allow for the use of this software in laboratory conditions.

Conifold Transitions and Five-Brane Condensation in M-Theory on Spin(7) Manifolds

description: We conjecture a topology changing transition in M-theory on a non-compact asymptotically conical Spin(7) manifold, where a 5-sphere collapses and a CP(2) bolt grows. We argue that the transition may be understood as the condensation of M5-branes wrapping the 5-sphere. Upon reduction to ten dimensions, it has a physical interpretation as a transition of D6-branes lying on calibrated submanifolds of flat space. In yet another guise, it may be seen as a geometric transition between two phases of type IIA string theory on a G_2 holonomy manifold with either wrapped D6-branes, or background Ramond-Ramond flux. This is the first non-trivial example of a topology changing transition with only 1/16 supersymmetry.
