description: The emergence of the Internet of Things (IoT) has resulted in a significant increase in research on e-health. As the amount of patient data grows, it has become increasingly challenging to protect patients' privacy. Patient data is commonly stored in the cloud, making it difficult for users to control and protect their information. Moreover, the recent rise in security and surveillance breaches in the healthcare industry has highlighted the need for a better approach to data storage and protection. Traditional models that rely on third-party control over patients' healthcare data are no longer reliable, as they have proven vulnerable to security breaches. To address these issues, blockchain technology has emerged as a promising solution. Blockchain-based protocols have the potential to provide a secure and efficient system for e-health applications that does not require trust in third-party intermediaries. The proposed protocol outlined in this paper uses a blockchain-based approach to manage patient data securely and efficiently. Unlike Bitcoin, which is primarily used for financial transactions, the protocol described here is designed specifically for e-health applications. It employs a consensus mechanism that is more suitable for resource constrained IoT devices, thereby reducing network costs and increasing efficiency. The proposed protocol also provides a privacy-preserving access control mechanism that enables patients to have more control over their healthcare data. By leveraging blockchain technology, the protocol ensures that only authorized individuals can access the patient's data, which helps prevent data breaches and other security issues. Finally, the security and privacy of the proposed protocol are analysed to ensure that it meets the necessary standards for data protection.

description: When a Brownian particle in contact with a heat bath at a constant temperature is controlled by a time-dependent harmonic potential, its distribution function can be rigorously derived from the Kramers equation with the consideration of the inertial effect of the Brownian particle. Based on this rigorous solution and the concept of shortcuts to adiabaticity, we construct a stochastic heat engine by employing the time-dependent harmonic potential to manipulate the Brownian particle to complete a thermodynamic cycle. We find that the efficiency at maximum power of this stochastic heat engine is equal to $1-\sqrt{T_c/T_h}$ where $T_c$ and $T_h$ are the temperatures of the cold bath and the hot one in the thermodynamic cycle, respectively.

description: We study the monodromy representation corresponding to a fibration introduced by G. Denham and A. Suciu, which involves polyhedral products given in Definition 2.2. Algebraic and geometric descriptions for these monodromy representations are given. In particular, we study the case of a product of two finite cyclic groups and obtain representations into $Out(F_n)$ and $SL_n(\mathbb Z)$. We give algebraic descriptions of monodromy for the case of a product of any two finite groups . Finally we give a geometric description for monodromy representations of a product of 2 or more finite groups to $Out(F_n)$, as well as some algebraic properties. The geometric description does not rely on choosing a basis for the fundamental group of the fibre in terms of commutators, hence avoids this delicate question.

Works of St. Ephrem the Syrian.  Volume 3
Creators: name: Assemani, Stefano Evodio

Publisher: name: No Publisher Supplied
Year: 2013

description: Begun by Peter Benedictus (Mobarak) and continued by Stephen Evodius Assemani, the great Roman edition of Ephrem’s works, based on Vatican manuscripts, was the result of the first major effort to publish the famous Syrian’s literary remains in large number. Volumes 1-3 contain the Syriac works with Latin translation, and volumes 4-6 contain works in Greek (and a small number in Latin) attributed to Ephrem, these too with Latin translation. This edition laid the foundation for further editions and translations of Ephrem’s works in Syriac by Overbeck, Bickell, Lamy, and others. While Ephrem’s Syriac corpus has been reedited more recently by Beck, this edition from a vital age of European Syriac scholarship remains worthy of study for its presentation and perspective. Scholars interested in Syriac literature and the history of its study in the west will be especially interested in this monumental edition.
Essays on forecasting macroeconomic variables using mixed frequency data
Creators: name: Kim, Kihwan
Publisher: name: No Publisher Supplied
Year: 2016

description: This dissertation investigate the forecasting performance of mixed frequency factor models with  mixed frequency dataset. In the first chapter, I consider the mixed fre-  quency factor approach used in ADS (2009) to construct their co-incident activity index, and ask  the question of whether a class of mixed frequency indexes is useful for predicting the future values  of quarterly U.S. real GDP growth and monthly industrial production, unemployment and inflation.  My forecasting assessment of the mixed frequency factor model is performed in conjunction with  standard prediction models such as autoregression, multivariate distributed lag models, and diffu-  sion index models of the variety examined by Stock and Watson (2002a). The main findings of the  study are as follows. First, prediction models using only mixed frequency indexes show their best  performance at short-term GDP forecasting horizons, and are particularly good during recessions.  Second, prediction models using both mixed frequency indexes and diffusion indexes forecast monthly  variables more accurately than models using single frequency type indexes. Third, model combi-  nations perform relatively poorly in real GDP forecasting contexts, although they perform better  when applied to the prediction of monthly variables. Fourth, survey information can be conveniently  exploited with higher frequency variables such as daily and weekly variables, and mixed frequency  indexes using such survey information are sometimes useful in forecasting lower frequency variables.  In the second chapter, I evaluate the predictive performance of hybrid models for forecasting four  economic variables. The hybrid approach takes into account the notion that simple autoregression  and sophisticated factor modelspredictive abilities may change according to the state of the econ-  omy. I find that hybrid prediction models produce better forecasts than standard models and than  combination models, in most cases, using the same menu of models discussed above. For example,  in one-quarter ahead GDP forecasts, the best hybrid model reduces the mean squared forecast error  of the best model combinations and the linear models by 14 and 11 percent, on average, respectively.  More specifically, the mean squared forecast error of autoregression is reduced by approximately 35  percent. In 12-month ahead predictions of inflation, the best hybrid model improves the best model  combinations and the linear models by 11 percent and 16 percent, on average, respectively. This  number again increases, in this case to 36 percent, when comparing only with autoregression. One  reason for these findings is that hybrid prediction models more effectively utilize survey information.

description: Principal component analysis (PCA) is an essential algorithm for dimensionality reduction in many data science domains. We address the problem of performing a federated PCA on private data distributed among multiple data providers while ensuring data confidentiality. Our solution, SF-PCA, is an end-to-end secure system that preserves the confidentiality of both the original data and all intermediate results in a passive-adversary model with up to all-but-one colluding parties. SF-PCA jointly leverages multiparty homomorphic encryption, interactive protocols, and edge computing to efficiently interleave computations on local cleartext data with operations on collectively encrypted data. SF-PCA obtains results as accurate as non-secure centralized solutions, independently of the data distribution among the parties. It scales linearly or better with the dataset dimensions and with the number of data providers. SF-PCA is more precise than existing approaches that approximate the solution by combining local analysis results, and between 3x and 250x faster than privacy-preserving alternatives based solely on secure multiparty computation or homomorphic encryption. Our work demonstrates the practical applicability of secure and federated PCA on private distributed datasets.

description: Degeneration of nigrostriatal dopaminergic neurons is the primary histopathological feature of Parkinson's disease. The neurotoxin MPTP (1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine) induces a neurological syndrome in man and non-human primates very similar to idiopathic Parkinson's disease by selectively destroying dopaminergic nigrostriatal neurons. This gives rise to the hypothesis that Parkinson's disease may be caused by endogenous or environmental toxins. Endogenous excitatory amino acids (EAAs) such as L-glutamate could be involved in neurodegenerative disorders including Parkinson's disease. We report in this study that the competitive NMDA antagonist CPP (3-((+/-)-2-carboxypiperazin-4-yl)-propyl-1-phosphonic acid) protects nigral tyrosine hydroxylase (TH) positive neurons from degeneration induced by systemic treatment with MPTP in common marmosets. This indicates that EAAs are involved in the pathophysiological cascade of MPTP-induced neuronal cell death and that EAA antagonists may offer a neuroprotective therapy for Parkinson's disease.

Contraversive turning decreased, and reversed its direction after about 30 min. Ipsiversive turning was still present 24 h after the injection of MPTP. These results suggest that MPTP has an initial stimulatory effect on dopaminergic neurons followed by a depression of the activity of these cells.

description: The study explored the relationship between mentorship, racially minoritized student stress, and mental health symptoms of ethnoracially minoritized Students of Color face unique challenges when navigating institutions of higher education structured by Eurocentrism. The scarcity of ethnoracially diverse faculty is an institutional microaggression that leaves Students of Color with a dearth of mentorship relationships provided by ethnoracially diverse faculty. This study explored if mentorship relationships influence ethnoracial microaggression related student stress and mental health symptoms of Students of Color and whether these relationships varied by ethnoracial identification of mentor and mentee. Additionally, the current study explored whether quality of mentorship moderated the relationship between racially minoritized student stress associated with ethnoracial microaggressions and mental health symptoms. The study found no significant relationship between mentorship relationships with White faculty or Faculty of Color and ethnoracial microaggression related stress or mental health symptoms. Furthermore, while the regression model was significant, this was due to the relationship between ethnoracially minoritized student stress and mental health symptoms. The relationship between ethnoracially minoritized student stress and mental health symptoms was not significantly moderated by the quality of mentorship relationships. The current findings were most likely influenced by an inadequate sample size. Despite efforts to recruit Students of Color with mentors throughout the nation and emailing cross cultural centers at universities throughout the United States, Students of Color with mentors remained an elusive demographic to recruit. Difficulty recruiting participants may be the result of the COVID-19 pandemic, or it may point to a lack of mentorship opportunities available to Students of Color.

description: With the increasing dominance of the internet as a source of news consumption, there has been a rise in the production and popularity of email newsletters compiled by individual journalists. However, there is little research on the processes of aggregation, and how these differ between expert journalists and trained machines. In this paper, we interviewed journalists who curate newsletters from around the world. Through an in-depth understanding of journalists' workflows, our findings lay out the role of their prior experience in the value they bring into the curation process, their use of algorithms in finding stories for their newsletter, and their internalization of their readers' interests and the context they are curating for. While identifying the role of human expertise, we highlight the importance of hybrid curation and provide design insights on how technology can support the work of these experts.

description: This work presents a technique for statistically modeling errors introduced by reduced-order models. The method employs Gaussian-process regression to construct a mapping from a small number of computationally inexpensive `error indicators' to a distribution over the true error. The variance of this distribution can be interpreted as the (epistemic) uncertainty introduced by the reduced-order model. To model normed errors, the method employs existing rigorous error bounds and residual norms as indicators; numerical experiments show that the method leads to a near-optimal expected effectivity in contrast to typical error bounds. To model errors in general outputs, the method uses dual-weighted residuals---which are amenable to uncertainty control---as indicators. Experiments illustrate that correcting the reduced-order-model output with this surrogate can improve prediction accuracy by an order of magnitude; this contrasts with existing `multifidelity correction' approaches, which often fail for reduced-order models and suffer from the curse of dimensionality. The proposed error surrogates also lead to a notion of `probabilistic rigor', i.e., the surrogate bounds the error with specified probability.

description: Time-frequency Schmidt (TFS) modes of ultrafast quantum states are naturally compatible with high bit-rate integrated quantum communication networks. Thus they offer an attractive alternative for the realization of high dimensional quantum optics. Here, we present a quantum pulse gate based on dispersion-engineered ultrafast frequency conversion in a nonlinear optical waveguide, which is a key element for harnessing the potential of TFS modes. We experimentally retrieve the modal spectral-temporal structure of our device and demonstrate a single-mode operation fidelity of 80\%, which is limited by experimental shortcomings. In addition, we retrieve a conversion efficiency of 87.7\% with a high signal-to-noise ratio of 8.8 when operating the quantum pulse gate at the single-photon level.

description: This contribution to the focus issue covers anisotropic flow in hybrid approaches. The historical development of hybrid approaches and their impact on the interpretation of flow measurements is reviewed. The major ingredients of a hybrid approach and the transition criteria between transport and hydrodynamics are discussed. The results for anisotropic flow in (event-by-event) hybrid approaches are presented. Some hybrid approaches rely on hadronic transport for the late stages for the reaction (so called afterburner) and others employ transport approaches for the early non equilibrium evolution. In addition, there are 'full' hybrid calculations where a fluid evolution is dynamically embedded in a transport simulation. After demonstrating the success of hybrid approaches at high RHIC and LHC energies, existing hybrid caluclations for collective flow observables at lower beam energies are discussed and remaining challenges outlined.

The economic effects of corporate income taxation
Creators: name: Liu, Li
Publisher: name: No Publisher Supplied
Year: 2011

description: This dissertation consists of three essays studying the economic impact of corporate income taxation. Chapter 1 models and estimates the incidence of the corporate  income tax under imperfect competition. Identification comes from variation in the  effective marginal tax rates across industry and time. The empirical results suggest  that labor shares the burden of corporate taxes. A ten percentage increase in the  tax rates decreases the average wage rate by 0.45-0.56 percent. Consistent with the  theoretical prediction, the elasticity of wage with respect to the tax rates increases  with the industry concentration. Labor bears at least 87 percent of the burden of  corporate income taxes.  The U.S. corporate income tax system provides investment incentives that vary  across asset types. In Chapter 2, I study the effect of corporate income taxes on the  allocation of new capital investment by constructing an industry-level panel data from  1962 to 1997. My preferred-IV estimates of the asset substitution elasticities suggest  a sizable interasset distortion e¤ect of corporate income taxes. Substitutability is  the strongest between machinery equipment and computing and electronic equipment. Compared to a revenue-neutral uniform tax scheme, differential corporate  income taxes cause under-investment in computing and electronic equipment and  over-investment in machinery and transportation equipment.  Corporations were taxed at a lower rate than non-corporate firms in the early  twentieth century. Chapter 3 examines the effect of relative taxation of corporate to  non-corporate income using state-level panel data during 1909-1919. I find that the  tax cost to incorporate had a significant impact on the corporate share of establishments and related economic activities including employment and production. The  regression results suggest a large response of income shifting -- about 1.5 to 2 more  times than the largest estimates in studies using more recent data. Income shifting was more responsive to the tax policies during the early days of income taxes. The implicit tax subsidy encourage about 8,300 business to be organized under the corporate form during this period.

Deterring predator pursuit and attracting potential mates? The conspicuous melanized tail display of the zebra-tailed lizard

description: The evolutionary significance of color expression in animals is often framed within either an interspecific (e.g., antipredator display) or intraspecific (e.g., mate choice) context. In part, this dichotomy stems from assumptions that the expression of conspicuous sexually selected traits likely hinders survival in the wild. Here we address the potential for natural and sexual selection to reinforce expression of a conspicuous tail bar pattern in zebra-tailed lizards (Callisaurus draconoides). In C. draconoides, display of this tail bar pattern has historically been considered an interspecific signal to deter predator pursuit. However, a putative honest link between the tail bar pattern and escape likelihood (e.g., sprint speed) is unknown. Further, studies on related taxa also support the potential for this trait to be informative as a signal of individual quality during mating interactions as well. We assessed variation in the morphology of male and female C. draconoides, and then evaluated how variation in morphology (emphasizing the tail bar pattern) contributed to variation in performance (sprint capacity) and, for males, variation in female preference. Males were larger than females, but size was unrelated to variation in tail bar number. Males sprinted faster than females overall, but tail bar number only mattered for males: specifically, males with more tail bars sprinted faster. Females also preferred males with more tail bars. Overall, our findings suggest that natural (mediated via an honest link between bar number and sprint speed) and sexual (mediated via a preference for males with more tail bars) selection may mutually reinforce expression of a color signal. Thus, the potential adaptive benefits of a color signal may span intra- and interspecific contexts. For males at least, the tail bar pattern is useful for both deterring the pursuit of predators as well as attracting the attention of potential mates.

description: Behavioral and neurophysiological studies in macaque monkeys suggest a role of the inferior temporal cortex in pattern discrimination and visual memory. To determine whether this cortical area is also involved in human short-term visual memory, we measured spatial frequency discrimination thresholds for sequentially presented stimuli in 17 patients with unilateral, postoperative focal damage to the temporal cortex (11 left, 6 right hemisphere). These results are compared to those of 17 age-matched control subjects. Contrast detection thresholds and difference thresholds for spatial frequency were determined for spatially truncated sine wave gratings presented in the left and right visual fields. Detection thresholds were measured for sine wave gratings in a spatial two-alternative forced-choice procedure for three spatial frequencies [2.5, 5, and 10 cycles (c)/degree] for each hemifield. Discrimination thresholds were determined for two gratings sequentially presented either 4 degrees to the left or right of fixation. Grating contrast was five times the value of detection threshold and reference frequency was 5 c/degree. Within each trial, the gratings were separated in time by 1, 3, and 10 sec interstimulus intervals (ISIs), and subjects signaled which grating had the higher spatial frequency. The results indicate that (1) contrast detection thresholds overall did not differ between patient and control groups; (2) spatial frequency discrimination thresholds were, however, significantly elevated in patients and this elevation was significantly more pronounced in the visual field contralateral to the damaged hemisphere; and (3) patients with inferotemporal damage exhibited higher discrimination thresholds for the longest ISI, whereas patients with medial/superior temporal lobe damage did not show this effect. The results suggest that visual areas in human temporal cortex are involved in the higher visual processes underlying delayed pattern discrimination.

description: We have measured the 2-particle correlation function of atoms from a Bose--Einstein condensate participating in a superradiance process, which directly reflects the 2nd order coherence of the emitted light. We compare this correlation function with that of atoms undergoing stimulated emission. Whereas the stimulated process produces correlations resembling those of a coherent state, we find that superradiance, even in the presence of strong gain, shows a correlation function close to that of a thermal state, just as for ordinary spontaneous emission.

description: We have studied the superconducting Si(111)-(root7xroot3)-In surface using a 3He-based low-temperature scanning tunneling microscope (STM). Zero-bias conductance (ZBC) images taken over a large surface area reveal that vortices are trapped at atomic steps after magnetic fields are applied. The crossover behavior from Pearl to Josephson vortices is clearly identified from their elongated shapes along the steps and significant recovery of superconductivity within the cores. Our numerical calculations combined with experiments clarify that these characteristic features are determined by the relative strength of the interterrace Josephson coupling at the atomic step.

description: Unilateral intranigral injections of MPTP (1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine) and MPP+ (1-methyl-4-phenylpyridine) were given to young rats and unilateral intranigral injections of MPTP were given to old rats. MPTP in old rats and MPP+ in young rats induced ipsiversive circling for at least one week after injection and contraversive circling after the systemic administration of apomorphine; the number of D-2 receptors (Bmax) in the striatum of the injected hemisphere increased compared with that of control rats. MPTP in young rats induced only short-lasting ipsiversive circling and no contraversive circling after apomorphine; the number of striatal D-2 receptors did not increase. These results suggest that the neurotoxicity of MPTP is age-dependent in the rat, and that MPTP has neurotoxic effects on the nigrostriatal dopaminergic system in old rats and induces dopamine receptor supersensitivity in the denervated striatum.

description: Old and young adult rats received unilateral injections of MPTP or saline into the substantia nigra. Unilateral injection of MPTP in old rats induced ipsiversive circling on day 1 and day 7 after the injection; contraversive circling behavior was induced in MPTP-treated rats by systemic administration of apomorphine. Young rats showed ipsiversive circling on day 1 but not on day 7 after the injection; administration of apomorphine did not induce contraversive circling. On day 10 after the injection of MPTP, the concentration of D-2 receptors in the striatum of the injected hemisphere of old rats was increased by about 25% compared with the striatum of old rats with saline injection and of young rats with MPTP or saline injections. These results suggest that MPTP exerts neurotoxic effects on the nigrostriatal dopaminergic system of old rats and produces supersensitive dopamine receptors in the ipsilateral denervated striatum.

description: Slow light based on the effect of electromagnetically induced transparency is of great interest due to its applications in low-light-level nonlinear optics and quantum information manipulation. The previous experiments all dealt with the single-component slow light. Here we report the experimental demonstration of two-component or spinor slow light using a double tripod atom-light coupling scheme. The scheme involves three atomic ground states coupled to two excited states by six light fields. The oscillation due to the interaction between the two components was observed. Based on the stored light, our data showed that the double tripod scheme behaves like the two outcomes of an interferometer enabling precision measurements of frequency detuning. We experimentally demonstrated a possible application of the double tripod scheme as quantum memory/rotator for the two-color qubit. Our study also suggests that the spinor slow light is a better method than a widely-used scheme in the nonlinear frequency conversion.

description: The vibrissae of rats were shaved from one side of the face daily for 10 days. To see whether or not this treatment had an effect on crossed and uncrossed striatal afferent connections from the midbrain, the tract tracer horseradish peroxidase was applied to the caudate-putamen on day 11. When the tracer was deposited on the side opposite the vibrissae removal, more labeled cells were found in the contralateral substantia nigra than when it was applied on the same side as the vibrissae removal, or placed in animals with intact vibrissae. Unilateral removal of vibrissae did not affect uptake of the tracer by the cells which give rise to the homolateral nigrostriatal projections. These changes in HRP labeling in the crossed projection from the substantia nigra were seen after 10 days of unilateral removal of the vibrissae; i.e., at a time when the animals have had opportunity to learn to compensate for vibrissotomy-induced behavioral asymmetries.

description: Urban-dwelling birds face novel visual cues and soundscapes. To thrive in these challenging environments, individuals must correctly identify and calibrate threats posed by humans and their activities. We showed that Dark-eyed juncos (Junco hyemalis) residing in an urban habitat responded differently to the sounds that approaching people and objects make. A person approached juncos simultaneously playing the sounds of object types that normally move at different relative velocities: faster (bicycles), intermediate (skateboards and scooters), or slower (people walking). Juncos responded at significantly greater distances and moved further in relation to what sound cues would normally imply about the velocity of approach. Absolute stimulus volume was not a significant predictor of response across object type. The responses occurred without the presence of visual cues, suggesting that an auditory cue alone and without visual confirmation can produce an appropriate response. Overall, this shows that this population of urban juncos has the ability to respond appropriately to novel anthropogenic sound cues. The question remains as to how universal such abilities are across species, different urban situations, and in natural habitats.
Bounds on $\mathcal{N}=1$ Superconformal Theories with Global Symmetries

description: Recently, the conformal-bootstrap has been successfully used to obtain generic bounds on the spectrum and OPE coefficients of unitary conformal field theories. In practice, these bounds are obtained by assuming the existence of a scalar operator in the theory and analyzing the crossing-symmetry constraints of its 4-point function. In $\mathcal{N}=1$ superconformal theories with a global symmetry there is always a scalar primary operator, which is the top of the current-multiplet. In this paper we analyze the crossing-symmetry constraints of the 4-point function of this operator for $\mathcal{N}=1$ theories with $SU(N)$ global symmetry. We analyze the current-current OPE, and derive the superconformal blocks, generalizing the work of Fortin, Intrilligator and Stergiou to the non-Abelian case and finding new superconformal blocks which appear in the Abelian case. We then use these results to obtain bounds on the coefficient of the current 2-point function.
