description: Perinatal depression is complex, and the etiology remains poorly understood which likely contributes to its underdiagnosis and being a leading cause of maternal mortality. This dissertation used a mixed methods approach to explore biopsychosocial and behavioral factors influencing perinatal depression and aimed to generate evidence for the development of a comprehensive risk phenotype. The systematic review indicated a total of 14 categories of determinants were investigated: biological (5), behavioral (4), social and environmental (5). Though only 28% of studies simultaneously considered determinants under more than one domain, a pattern of interactions with the tryptophan pathway emerged once determinants across domains were aggregated. Methodological limitations related to depression measures and biospecimen collection were identified. Qualitative findings indicated a network of structural factors act as barriers or facilitators to psychological well-being during the perinatal period. Social support, physical health, and logistics were commonly perceived as barriers during pregnancy, while physical health, logistics, and physical activity were seen as facilitators. In the postpartum period, barriers included logistics, social support, and physical health while the most common facilitators were social support, logistics, and nutrition. Mothers reported feelings of loneliness, isolation, worry, anxiety, frustration, and mental fatigue when facing barriers, which were heightened postpartum due to unmet expectations of increased support. Conversely, facilitators improved mothers’ ability to cope with stress and helped mothers find positive aspects about their situation when faced with challenges in motherhood. The metabolomics pilot study found gut gamma-aminobutyric acid (GABA) to be significantly lower postpartum compared to levels in the second and third trimesters. However, correlations among changes in individual pregnancy metabolites and postpartum depression were weak and no predictive models were significant suggesting individual metabolites may not serve as robust predictors of postpartum depression. These findings support perinatal depression is a multifactorial condition, and exploration of complex interactions between biopsychosocial and behavioral factors may provide a more holistic understanding of the pathophysiology. Thus, future research considering a comprehensive panel of variables in large and diverse samples is needed to replicate and build upon the present findings and further refine the phenotypic characteristics of perinatal depression described in this dissertation.

description: Robotic fiber positioner (RFP) arrays are becoming heavily adopted in wide field massively multiplexed spectroscopic survey instruments. RFP arrays decrease nightly operational overheads through rapid reconfiguration between fields and exposures. In comparison to similar instruments, SDSS-V has selected a very dense RFP packing scheme where any point in a field is typically accessible to three or more robots. This design provides flexibility in target assignment. However, the task of collision-less trajectory planning is especially challenging. We present two multi-agent distributed control strategies that are highly efficient and computationally inexpensive for determining collision-free paths for RFPs in heavily overlapping workspaces. We demonstrate that a reconfiguration path between two arbitrary robot configurations can be efficiently found if "folded" state, in which all robot arms are retracted and aligned in a lattice-like orientation, is inserted between the initial and final states. Although developed for SDSS-V, the approach we describe is generic and so applicable to a wide range of RFP designs and layouts. Robotic fiber positioner technology continues to advance rapidly, and in the near future ultra-densely packed RFP designs may be feasible. Our algorithms are especially capable in routing paths in very crowded environments, where we see efficient results even in regimes significantly more crowded than the SDSS-V RFP design.

description: In the last three decades, Russia has withdrawn from the short-lived experiment with democracy that began with the collapse of the Soviet Union. In the wake of waning stability at home and growing tensions with the "near abroad" and liberal democracies of the West, the Putin regime continues to drive Russian society into cultural conservatism and authoritarianism. History and its commemoration have served as key tools for Putin and his United Russia party, as evidenced by the recent push to legislate memory of the Soviet Union’s victory over Nazi Germany in the Great Patriotic War (WWII). This report aims to consolidate the literature on memory politics in Russia and focuses on the impact of one law in particular: Article 354.1 of the Russian Criminal Code, the "Rehabilitation of Nazism," first introduced in 2009, passed in 2014, and expanded in 2021. This report analyzes the law through two lenses, (1) the law as an imitation of European memory laws, and (2) the law as a reflection of the Kremlin’s effort to construct a positive Russian national identity

description: We investigate the orientation of the axes and angular momentum of dark matter halos with respect to their neighboring voids using high resolution N-body cosmological simulations. We find that the minor axis of halos tends to be aligned along the line joining the halo with the center of the void, and that the major axis is perpendicular to this line. However, we find that the angular momentum of halos does not have any particular orientation. These results may provide information about the mechanisms whereby the large-scale structure of the Universe affects galaxy formation and cast light upon the issue of the orientation of galaxy disks with respect to their host halos.

description: We construct new supersymmetric multi-black ring solutions on the Eguchi-Hanson base space as solutions of the five-dimensional minimal supergravity. The space-time has an asymptotically locally Euclidean time slice, i.e., it has the spatial infinity with the topology of the lens space $L(2;1)=S^3/Z_2$. The configurations of black rings are restricted by the requirement of the absence of a Dirac-Misner string everywhere outside horizons. Especially, in the case of two black rings, the solutions have the limit to a pair of rotating black holes with the horizon topology of S^3.

description: Fully automated classification methods that yield direct physical insights into phase diagrams are of current interest. Here, we demonstrate an unsupervised machine learning method for phase classification which is rendered interpretable via an analytical derivation of its optimal predictions and allows for an automated construction scheme for order parameters. Based on these findings, we propose and apply an alternative, physically-motivated, data-driven scheme which relies on the difference between mean input features. This mean-based method is computationally cheap and directly interpretable. As an example, we consider the physically rich ground-state phase diagram of the spinless Falicov-Kimball model.

description: The number of maximal independent sets of the n-cycle graph C_n is known to be the nth term of the Perrin sequence. The action of the automorphism group of C_n on the family of these maximal independent sets partitions this family into disjoint orbits, which represent the non-isomorphic (i.e., defined up to a rotation and a reflection) maximal independent sets. We provide exact formulas for the total number of orbits and the number of orbits having a given number of isomorphic representatives. We also provide exact formulas for the total number of unlabeled (i.e., defined up to a rotation) maximal independent sets and the number of unlabeled maximal independent sets having a given number of isomorphic representatives. It turns out that these formulas involve both Perrin and Padovan sequences.

description: The technological advancements made in recent times, particularly in Artificial Intelligence (AI) and Quantum Computing, have brought about significant changes in technology. These advancements have profoundly impacted quantum cryptography, a field where AI methodologies hold tremendous potential to enhance the efficiency and robustness of cryptographic systems. However, the emergence of quantum computers has created a new challenge for existing security algorithms, commonly called the 'quantum threat'. Despite these challenges, there are promising avenues for integrating neural network-based AI in cryptography, which has significant implications for future digital security paradigms. This summary highlights the key themes in the intersection of AI and quantum cryptography, including the potential benefits of AI-driven cryptography, the challenges that need to be addressed, and the prospects of this interdisciplinary research area.

description: La vaccinazione è uno dei maggiori successi della sanità pubblica della nostra epoca e negli ultimi sessanta anni ha salvato la vita a più persone di qualsiasi altro intervento medico; l’uomo infatti non ha mai avuto a disposizione armi preventive più efficaci delle vaccinazioni. Gli ambienti di vita e di lavoro, sono potenzialmente contaminati da microrganismi patogeni e il rischio di contrarre una malattia infettiva è insito nel fatto di vivere in comunità (rischio generico). All’interno di una struttura sanitaria, in determinate aree e nel corso di definite attività, a causa della concentrazione di soggetti infetti e materiali contaminati, tale rischio può essere maggiore (rischio lavorativo da esposizione ad agenti biologici: potenziale o deliberato). Vaccination is one of the greatest public health successes of our time and in the last sixty years it has saved the lives of more people than any other medical intervention; in fact, man has never had more effective preventive weapons than vaccinations. Living and working environments are potentially contaminated by pathogenic microorganisms and the risk of contracting an infectious disease is inherent in the fact of living in community (generic risk). Within a health facility, in certain areas and during defined activities, due to the concentration of infected subjects and contaminated materials, this risk may be greater (work risk from exposure to biological agents: potential or deliberate).

description: The term activity is used in an imprecise way but generally refers to a larger interactional unit within which an action performed by an individual is embedded (e.g., Goodwin & Goodwin 1987). It is a nameable unit, having an approximate beginning and end, and therefore it makes sense to talk about the transition between activities (e.g., Robinson & Stivers, 2001) and a multiactivity situation (Haddington, et al. 2014), although activities may not always be well bounded as units (see Sacks, et al. 1974).

description: The Advanced Atacama Cosmology Telescope Polarimeter (AdvACT) \cite{thornton} is an upgrade for the Atacama Cosmology Telescope using Transition Edge Sensor (TES) detector arrays to measure cosmic microwave background (CMB) temperature and polarization anisotropies in multiple frequencies. The low frequency (LF) array was deployed early 2020. It consists of 292 TES bolometers observing in two bands centered at 27 GHz and 39 GHz. At these frequencies, it is sensitive to synchrotron radiation from our galaxy as well as to the CMB, and complements the AdvACT arrays operating at 90, 150 and 230 GHz. We present the initial LF array on-site characterization, including the time constant, optical efficiency and array sensitivity.

description: Spectroscopic factors to low-lying negative-parity states in $^{11}$Be extracted from the $^{12}$B($d$,$^3$He)$^{11}$Be proton-removal reaction are interpreted within the rotational model. Earlier predictions of the $p$-wave proton removal strengths in the strong coupling limit of the Nilsson model underestimated the spectroscopic factors to the $3/2^-_1$ and $5/2^-_1$ states and suggested that deviations in the $1^+$ ground state of the odd-odd $^{12}$B due to Coriolis coupling should be further explored. In this work we use the Particle Rotor Model to take into account these effects and obtain a good description of the level scheme in $^{11}$B, with a moderate $K$-mixing of the proton Nilsson levels [110]1/2 and [101]3/2. This mixing, present in the $1^+$ bandhead of $^{12}$B, is key to explaining the proton pickup data.

description: We present Gemini GMOS IFU observations of six massive ($M_\star\geq10^{11} \ M_\odot$) A-star dominated post-starburst galaxies at $z\sim0.6$. These galaxies are a subsample of the SQuIGG$\vec{L}$E Survey, which selects intermediate-redshift post-starbursts from the Sloan Digital Sky Survey spectroscopic sample (DR14) with spectral shapes that indicate they have recently shut off their primary epoch of star formation. Using $Hδ_A$ absorption as a proxy for stellar age, we constrain five of the galaxies to have young ($\sim 600$ Myr) light-weighted ages at all radii and find that the sample on average has flat age gradients. We examine the spatial distribution of mass-weighted properties by fitting our profiles with a toy model including a young, centrally concentrated burst superimposed on an older, extended population. We find that galaxies with flat $Hδ_A$ profiles are inconsistent with formation via a central secondary starburst. This implies that the mechanism responsible for shutting off this dominant episode of star formation must have done so uniformly throughout the galaxy.

description: We study the nature of energy release and transfer for two sub-A class solar microflares observed during the second flight of the Focusing Optics X-ray Solar Imager (FOXSI-2) sounding rocket experiment on 2014 December 11. FOXSI is the first solar-dedicated instrument to utilize focusing optics to image the Sun in the hard X-ray (HXR) regime, sensitive to the energy range 4-20 keV. Through spectral analysis of the two microflares using an optically thin isothermal plasma model, we find evidence for plasma heated to temperatures of ~10 MK and emissions measures down to ~$10^{44}~$cm$^{-3}$. Though nonthermal emission was not detected for the FOXSI-2 microflares, a study of the parameter space for possible hidden nonthermal components shows that there could be enough energy in nonthermal electrons to account for the thermal energy in microflare 1, indicating that this flare is plausibly consistent with the standard thick-target model. With a solar-optimized design and improvements in HXR focusing optics, FOXSI-2 offers approximately five times greater sensitivity at 10 keV than the Nuclear Spectroscopic Telescope Array (NuSTAR) for typical microflare observations and allows for the first direct imaging spectroscopy of solar HXRs with an angular resolution at scales relevant for microflares. Harnessing these improved capabilities to study the evolution of small-scale events, we find evidence for spatial and temporal complexity during a sub-A class flare. These studies in combination with contemporanous observations by the Atmospheric Imaging Assembly onboard the Solar Dynamics Observatory (SDO/AIA) indicate that the evolution of these small microflares is more similar to that of large flares than to the single burst of energy expected for a nanoflare.

description: Estimating the degree of synchrony or reliability between two or more spike trains is a frequent task in both experimental and computational neuroscience. In recent years, many different methods have been proposed that typically compare the timing of spikes on a certain time scale to be fixed beforehand. Here, we propose the ISI-distance, a simple complementary approach that extracts information from the interspike intervals by evaluating the ratio of the instantaneous frequencies. The method is parameter free, time scale independent and easy to visualize as illustrated by an application to real neuronal spike trains obtained in vitro from rat slices. In a comparison with existing approaches on spike trains extracted from a simulated Hindemarsh-Rose network, the ISI-distance performs as well as the best time-scale-optimized measure based on spike timing.

description: We adapt the Jain--Taylor (2003) shear-ratio geometric lensing method to measure the dark energy equation of state, and its time derivative from dark matter haloes in cosmologies with arbitrary spatial curvature. The full shear-ratio covariance matrix is calculated for lensed sources, including the intervening large-scale structure and photometric redshift errors as additional sources of noise, and a maximum likelihood method for applying the test is presented. Combining with the expected results from the CMB we design an optimal survey for probing dark energy. A targeted survey imaging 60 of the largest clusters in a hemisphere with 5-band optical photometric redshifts to a median galaxy depth of zm=0.9 could measure w0 to a marginal 1-sigma error of $Δ$w0=0.5. We marginalize over all other parameters including wa, where the equation of state is parameterized in terms of scale factor a as w(a)=w0+wa(1-a). For higher accuracy a large-scale photometric redshift survey is required. Such a near-future 5-band survey covering 10,000 square degrees to z_m=0.7 could measure w0 to $Δ$w0=0.075 and $Δ$wa=0.33. A stronger combined constraint is measured at a pivot redshift zp=0.27 of $Δ$w(zp)=0.0298. We compare and combine the geometric test with the cosmological and dark energy parameters measured from planned Baryon Acoustic Oscillation (BAO) and supernova Type Ia experiments, and find that the geometric test results combine with a significant reduction in errors due to different degeneracies. A combination of geometric lensing, CMB and BAO experiments could achieve a pivot redshift constraint of $Δ$w(zp)=0.020 at zp=0.62. Simple relations are presented that show how our lensing results can be scaled to other telescope classes and survey parameters.

The analysis of stability is based on the Lyapunov and Reversibility error. It is found that the error growth follows a power law for regular orbits and an exponential law for chaotic orbits. A relation with the Shannon channel capacity is devised and an approximate scaling law found for the capacity increase with the corrugation depth.

Design and development of a high force actuator using giant magnetostrictive material
Creators: name: Fung, Kam
Publisher: name: University of British Columbia
Year: 2009

description: With the maturity of manufacturing process for the giant magnetostrictive material called Terfenol-D, high force and high precision actuators can now be realized at a reasonable cost. These actuators can be used in many applications, one of them being the control of machine chatter vibration. This violent phenomenon is one of the limiting factors on how fast a metal-cutting operation can proceed. In chapter 1 a discussion of chatter vibration is presented. Terfenol-D possesses some unique properties that affect actuator design; therefore an understanding of the magnetoelastic mechanism is essential. A basic discussion of magnetic material is first presented in appendix A; then properties unique to Terfenol-D are discussed in chapter 2. The design of the actuator at UBC is presented in chapter 3. It incorporates many features not found in existing designs. In particular, the push-pull configuration makes it suitable for applications requiring bi-directional movements. Preliminary test results of the device built are presented in chapter 4. Before Terfenol-D can be widely used, however, the problem of modelling and control has to be solved. Because of hysteresis and other nonlinearities, ordinary linear design techniques may not be applicable. Some promising nonlinear control strategies based on Preisach model and neural networks are discussed in the last chapter.

description: The recent realization of pristine Majorana zero modes (MZMs) in vortices of iron-based superconductors (FeSCs) provides a promising platform for long-sought-after fault-tolerant quantum computation. A large topological gap between the MZMs and the lowest excitations enabled detailed characterization of vortex MZMs in those materials. Despite those achievements, a practical implementation of topological quantum computation based on MZM braiding remains elusive in this new Majorana platform. Among the most pressing issues are the lack of controllable tuning methods for vortex MZMs and inhomogeneity of the FeSC Majorana compounds that destroys MZMs during the braiding process. Thus, the realization of tunable vortex MZMs in a truly homogeneous compound of stoichiometric composition and with a charge neutral cleavage surface is highly desirable. Here we demonstrate experimentally that the stoichiometric superconductor LiFeAs is a good candidate to overcome these two obstacles. Using scanning tunneling microscopy, we discover that the MZMs, which are absent on the natural surface, can appear in vortices influenced by native impurities. Our detailed analysis and model calculations clarify the mechanism of emergence of MZMs in this material, paving a way towards MZMs tunable by controllable methods such as electrostatic gating. The tunability of MZMs in this homogeneous material offers an unprecedented platform to manipulate and braid MZMs, the essential ingredients for topological quantum computation.

description: We present here some recent results concerning scalar-tensor Dark Energy models. These models are very interesting in many respects: they allow for a consistent phantom phase, the growth of matter perturbations is modified. Using a systematic expansion of the theory at low redshifts, we relate the possibility to have phantom like DE to solar system constraints.

description: Advances in space weather science and small satellite (SmallSat) technology have proceeded in parallel over the past two decades, but better communication and coordination is needed among the respective worldwide communities contributing to this rapid progress. We identify six areas where improved international coordination is especially desirable, including: (1) orbital debris mitigation; (2) spectrum management; (3) export control regulations; (4) access to timely and low-cost launch opportunities; (5) inclusive data policies; and (6) education. We argue the need for internationally coordinated policies and programs to promote the use of SmallSats for space weather research and forecasting while realizing maximum scientific and technical advances through the integration of these two increasingly important endeavors.

Местное управление в Грузии в период российской оккупации (1801-1917 гг.)

description: Under the occupation of the Russian Empire (1802), the former Kingdom of Kartli-Kakheti was divided into new administrative units: five counties and several district units. County administrative units were governed by "The national police" and the "court of county".  Russian military officials were appointed to the highest administrative positions in counties, they were called captain-ispravniks. They sought a similar division in the former Kingdom of Imereti (1810), although in reality the Kingdom of Imereti was governed by the kingdom's primary ruler, alongside some local officials (Mouravi, Mdivanbeg) who combined administrative, judicial, and financial functions. In 1841-1842 the governance of the counties changed: the counties were governed by the heads of the county, their assistants, the district judge, the city police, the county treasurers, the county courts, and the county prosecutor. Following the abolition of serfdom in 1865, rural self-government was implemented. The village assembly was considered the highest ruling authority, which involved the participation of the heads of the families. The assembly elected officials, including the village headman and judges for the term of 3 years. The implemented reforms did not contribute to the establishment of true self-governance in those areas; rather, they served to strengthen the Russian government and were imperial in nature.

Issue of validity of the criminal law in time and space

description: The article deals with issues  of validity of the criminal law in time and space, such as: How to understand the followoing entry in Article 2 of the Civil Code of Georgia: "When the executor acted or should have acted"? Does the time of the act mean only the time of the attempt to commit the crime, or also the time of the preparation of the crime? What time will be considered as the time of committing the crime when along with the preparation of the crime, there is also an attempt of crime committed? When a person prepares a crime in the territory of one country (eg, Georgia) and tries to commit it in the territory of another country, what time will be considered as the time of committing the crime? How should the issue of the time of the crime be resolved when a citizen of different countries (ie, a group of persons) prepares a crime on the territory of one country, and attempts to commit it on the territory of another country?

description: Klyachko and coworkers consider an orthogonality graph in the form of a pentagram, and in this way derive a Kochen-Specker inequality for spin 1 systems. In some low-dimensional situations Hilbert spaces are naturally organised, by a magical choice of basis, into SO(N) orbits. Combining these ideas some very elegant results emerge. We give a careful discussion of the pentagram operator, and then show how the pentagram underlies a number of other quantum "paradoxes", such as that of Hardy.

Позиция грузинских депутатов Государственной Думы Российской империи по вопросам Польши и Финляндии

description: The history of Georgian-Polish relations goes back more than five centuries. The fou­n­da­ti­ons of this relationship were laid in 1494, when the ambassadors of the king of the Kar­ta­linia/Kartli (Central Georgia) – Konstantine II Bagrationi (Reigned in 1478-1505), on their way to the East, arrived in Poland. They invited the King of Poland – John I Albert/Jan I Olbracht (Reigned in 1492-1501) to join the anti-Osman coalition. Georgian-Polish relations have been intensive since the 19th century, when Georgia and Poland, having lost their state independence, found themselves within the boundaries of the Russian Empire. The leading political figures of the Georgian and Polish peoples, who were fighting for the restoration of national statehood, considered each other allies and closely cooperated. This was involuntarily facilitated by the Russian imperial power, which exiled a significant part of the Poles fighting for independence to Georgia, and the Georgians to Poland. In the State Duma of the Russian Empire, deputies from Georgia took a very progressive position on issues related to Poland or Finland, supporting the national interests of these countries. One part of the Georgian deputation, which represented the Social Democratic Party, was led by the well-known Georgian politician Nikolai/Carlo Chkheidze (1864-1926), who was considered one of the leaders of the minorist trend of Russian and Georgian social democracy. He and Yevgeny Gegechkori, a member of the State Duma and a prominent Georgian social democrat, openly expressed their sympathy for the Polish people.

description: We announce the discovery of SST-Lup3-1, a very low mass star close to the brown dwarf boundary in Lupus III with a circum(sub)stellar disk, discovered by the `Cores to Disks' Spitzer Legacy Program from mid-, near-infrared and optical data, with very conspicuous crystalline silicate features in its spectrum. It is the first of such objects with a full 5 to 35 micron spectrum taken with the IRS and it shows strong 10 and 20 micron silicate features with high feature to continuum ratios and clear crystalline features out to 33 micron. The dust in the disk upper layer has a crystalline silicate grain fraction between 15% and 33%, depending on the assumed dust continuum. The availability of the full Spitzer infrared spectrum allows an analysis of the dust composition as a function of temperature and position in the disk. The hot (~ 300 K) dust responsible for the 10 micron feature consists of a roughly equal mix of small (~ 0.1 micron) and large (~ 1.5 micron) grains, whereas the cold (~ 70 K) dust responsible for the longer wavelength silicate features contains primarily large grains (> 1 micron). Since the cold dust emission arises from deeper layers in the inner (< 3 AU) disk as well as from the surface layers of the outer (3-5 AU) disk, this provides direct evidence for combined grain growth and settling in the disk. The inferred crystalline mass fractions in the two components are comparable. Since only the inner 0.02 AU of the disk is warm enough to anneal the amorphous silicate grains, even the lowest fraction of 15% of crystalline material requires either very efficient mixing or other formation mechanisms.
