description: Cancer immunotherapy trials are frequently characterized by a delayed treatment effect that violates the proportional hazards assumption. The log-rank test (LRT) suffers a substantial loss of statistical power under the nonproportional hazards model. Various group sequential designs using weighted LRTs (WLRTs) have been proposed under the fixed delayed treatment effect model. However, patients enrolled in immunotherapy trials are often heterogeneous, and the duration of the delayed treatment effect is a random variable. Therefore, we propose group sequential designs under the random delayed effect model using the random delayed distribution WLRT. The proposed group sequential designs are developed for monitoring the efficacy of the trial using the method of Lan-DeMets alpha-spending function with O’Brien-Fleming stopping boundaries or a gamma family alpha-spending function. The maximum sample size for the group sequential design is obtained by multiplying an inflation factor with the sample size for the fixed sample design. Simulations are conducted to study the operating characteristics of the proposed group sequential designs. The robustness of the proposed group sequential designs for misspecifying random delay time distribution and domain is studied via simulations.

description: Context. Most massive stars are in binary or multiple systems. Several massive stars have been detected as doublelined spectroscopic binaries and among these, the OWN Survey has detected a non-negligible number whose components show very different spectral line broadening (i.e., projected rotational velocities). This fact raises a discussion about the contributing processes, such as angular-momentum transfer and tidal forces. Aims. We seek to constrain the physical and evolutionary status of one of such systems, the O+O binary HD 93343. Methods. We analyzed a series of high-resolution multiepoch optical spectra to determine the orbital parameters, projected rotational velocities, and evolutionary status of the system. Results. HD 93343 is a binary system comprised of two O7.5 Vz stars that each have minimum masses of approximately 22 Mo in a wide and eccentric orbit (e = 0.398$\pm$0.004; P=50.432$\pm$0.001 d). Both stars have very similar stellar parameters, and hence ages. As expected from the qualitative appearance of the combined spectrum of the system, however, these stars have very different projected rotational velocities (~65 and ~325 km/s, respectively). Conclusions. The orbits and stellar parameters obtained for both components seem to indicate that their youth and relative separation is enough to discard the effects of mass transfer and tidal friction. Thus, non-synchronization should be intrinsic to their formation.

description: We investigate the properties of sparse matrix ensembles with particular regard for the spectral ergodicity hypothesis, which claims the identity of ensemble and spectral averages of spectral correlators. An apparent violation of the spectral ergodicity is observed. This effect is studied with the aid of the normal modes of the random matrix spectrum, which describe fluctuations of the eigenvalues around their average positions. This analysis reveals that spectral ergodicity is not broken, but that different energy scales of the spectra are examined by the two averaging techniques. Normal modes are shown to provide a useful complement to traditional spectral analysis with possible applications to a wide range of physical systems.

description: It is commonly necessary to perform inferences on the difference, ratio, and odds ratio of two proportions p1 and p2 based on two independent samples. For this purpose, the most common asymptotic statistics are based on the score statistics (S-type statistics). As these do not correct the bias of the estimator of the product pi (1–pi), Miettinen and Nurminen proposed the MN-type statistics, which consist of multiplying the statistics S by (N–1)/N, where N is the sum of the two sample sizes. This paper demonstrates that the factor (N–1)/N is only correct in the case of the test of equality of two proportions, providing the estimation of the correct factor (AU-type statistics) and the minimum value of the same (AUM-type statistics). Moreover, this paper assesses the performance of the four-type statistics mentioned (S, MN, AU and AUM) in one and two-tailed tests, and for each of the three parameters cited (d, R and OR). We found that the AUM-type statistics are the best, followed by the MN type (whose performance was most similar to that of AU-type). Finally, this paper also provides the correct factors when the data are from a multinomial distribution, with the novelty that the MN and AU statistics are similar in the case of the test for the odds ratio.
ACCULTURATION, DIET, AND CARDIOMETABOLIC RISK IN SOUTH ASIAN IMMIGRANTS

Year: 2024

description: First generation South Asian immigrants face a higher burden of cardiometabolic disease (CMD) than their native-born counterparts in the US (MatthewJoseph 2020). Traditional risk factors have been insufficient in explaining this health disparity. This scoping review aims to analyze the theoretical frameworks, study design, methods, and key findings documented in the literature to understand how the process of migration impacts the risk/prevalence of T2DM in SA immigrants. We found that acculturation, measured as length of residence, was positively associated with CMD risk, though the association between cultural dimensions of acculturation and the effect of dietary patterns on T2D risk is unclear. Future research should use 1) participatory methods to develop an ethnographically informed instrument to assess acculturation and 2) mixed methods to capture the physiological risk factors and diversity of dietary/cultural experiences after migration.

description: To explore and expand the application of luffa sponge (LS) fiber, three methods were used to chemically modify the LS fibers. The nanoindentation (NI) results show that the LS fibers exhibit a high elastic modulus (12.4 GPa) and hardness (0.7 GPa). Upon treating the fibers with 5%NaOH-5%H2O2, the NI hardness of the fibers increases by 14.3%. However, when 10%NaOH-20%CH3COOH (method B) is used, the hardness of the cell walls decreases by 28.6%. In this case, the removal of amorphous substances from the LS fibers and the swelling reaction of the LS cellulose plays a significant role. Three chemical treatments can partially remove the hemicellulose in the LS fiber. 18%NaOH-1.6%CO(NH2)2 (method C) modifies the crystalline structure of the cellulose in the LS fibers. Gas chromatography-mass spectrometry results show that the LS fibers are rich in hexadecanoic acid (14.3%), as well as in substances, such as squalene, oleic acid, and behenic alcohol, which exhibit a high antibiofilm activity. Furthermore, method B increases the total relative content of squalene and squalane in the LS extract by 49.4%; while method C treatment allows LS fibers have the potential to be used to develop phase-change energy storage materials and anti-photoaging discoloration materials.

description: We report a new class of $c$-axis Josephson tunneling experiments in which a conventional superconductor (Pb) is deposited across a single twin boundary of a YBa_2Cu_3O_{7-δ} crystal. We measure the critical current as a function of magnitude and angle of magnetic field applied in the plane of the junction. In all samples, we observe a clear experimental signature of an order parameter phase shift across the twin boundary. These results provide strong evidence for mixed $d$- and $s$-wave pairing in YBCO, with a reversal in the sign of the $s$-wave component across the twin boundary.

description: Conference realignment is a multifaceted phenomenon that involves numerous aspects. Within the realm of college athletics, realignments within the Autonomy Five conferences are particularly complex due to the higher stakes and financial considerations involved. However, not all athletic administrators have direct experience with conference realignment. The ones who have undergone such changes possess valuable insights that could aid their colleagues navigate this complex process. This study aims to capture recommendations and experiences from such participants, creating a comprehensive guide to college administrators for future Autonomy Five conference realignments.

description: Frame coalescing is one of the most efficient techniques to manage the low power idle (LPI) mode supported by Energy Efficient Ethernet (EEE) interfaces. This technique enables EEE interfaces to remain in the LPI mode for a certain amount of time upon the arrival of the first frame (time-based coalescing) or until a predefined amount of traffic accumulates in the transmission buffer (size-based coalescing). This paper provides new insights on the practical efficiency limits of both coalescing techniques. In particular, we derive the fundamental limits on the maximum energy savings considering a target average frame delay. Additionally, we present new open-loop adaptive variants of both time-based and size-based coalescing techniques. These proposals dynamically adjust the length of the sleeping periods in accordance with actual traffic conditions to reduce energy consumption while keeping the average delay near a predefined value simultaneously. Analytical and simulation results show that the energy consumption of both proposals is comparable to the fundamental limits. Consequently, we recommend the usage of the time-based algorithm in most scenarios because of its simplicity as well as its ability to bound the maximum frame delay at the same time.

description: Combination therapies with multiple mechanisms of action can offer improved efficacy and/or safety profiles when compared to a single therapy with one mechanism of action. Consequently, the number of combination therapy studies have increased multi-fold, both in oncology and non-oncology indications. However, identifying the optimal doses of each drug in a combination therapy can require a large sample size and prolong study timelines, especially when full factorial designs are used. In this paper, we extend the MCP-Mod design of Bretz, Pinheiro, and Branson to a three-dimensional space to model the dose-response surface of a two-drug combination under the framework of Combination (Comb) MCP-Mod. The resulting model yields a set of dosages for each drug in the combination that elicits the target response so that an optimal dose for the combination can be selected for pivotal studies. We construct three-dimensional dose-response models for the combination and formulate the contrast test statistic to select the best model, which can then be used to select the optimal dose. Guidance to calculate power and sample size calculations are provided to assist study design. Simulation studies show that Comb MCP-Mod performs as well as the conventional multiple comparisons approach in controlling the family-wise error rate at the desired alpha level. However, Comb MCP-Mod is more powerful than the classical multiple comparisons approach in detecting dose-response relationships when treatment is non-null. The probability of correctly identifying the underlying dose-response relationship is generally higher when using Comb MCP-Mod than when using the multiple comparisons approach.

description: Asteroseismology has undergone a profound transformation as a scientific field following the CoRoT and Kepler space missions. The latter is now yielding the first measurements of latitudinal differential rotation obtained directly from oscillation frequencies. Differential rotation is a fundamental mechanism of the stellar dynamo effect. Our goal is to measure the amount of differential rotation in the solar analogues 16 Cyg A and B, which are the components of a binary system. These stars are the brightest observed by Kepler and have therefore been extensively observed, with exquisite precision on their oscillation frequencies. We modelled the acoustic power spectrum of 16 Cyg A and B using a model that takes into account the contribution of differential rotation to the rotational frequency splitting. The estimation was carried out in a Bayesian setting. We then inverted these results to obtain the rotation profile of both stars under the assumption of a solar-like functional form. We observe that the magnitude of latitudinal differential rotation has a strong chance of being solar-like for both stars, their rotation rates being higher at the equator than at the pole. The measured latitudinal differential rotation, defined as the difference of rotation rate between the equator and the pole, is $320\pm269$ nHz and $440^{+363}_{-383}$ nHz for 16 Cyg A and B, respectively, confirming that the rotation rates of these stars are almost solar-like. Their equatorial rotation rates are $535\pm75$ nHz and $565_{-129}^{+150}$ nHz. Our results are in good agreement with measurements obtained from spectropolarimetry, spectroscopy, and photometry. We present the first conclusive measurement of latitudinal differential rotation for solar analogues. Their rotational profiles are very close to those of the Sun. These results depend weakly on the uncertainties of the stellar parameters.

In the first case, the perturbative regime %takes place at $d\sim 30$, while in the second at $d\sim 25$, %in agreement with the fact that the relevant small parameter %of the theory is $\propto 1/(d (2-ξ))$. In addition to the perturbative results, the behavior of the anomaly for the sixth-order structure functions {\it vs} the velocity scaling exponent, $ξ$, is investigated and the resulting behavior discussed.

description: Application of Information Technology (IT) in the domain of Human Resource Management (HRM) systems is a sine qua non for any organization for successfully adopting and implementing Fourth Industrial Revolution (Industry 4.0). However, these systems are required to ensure non-biased, efficient, transparent and secure environment. Blockchain, a technology based on distributed digital ledgers, can help facilitate the process of successfully effectuating these specifications. A detailed literature review has been conducted to identify the current status of usage of Information Technology in the domain of Human Resource Management and how Blockchain can help achieve a smart, cost-effective, efficient, transparent and secure factory management system. A Blockchain based Recruitment Management System (BcRMS) as well as Blockchain based Human Resource Management System (BcHRMS) algorithm have been proposed. From the analysis of the results obtained through the case study, it is evident that the proposed system holds definite advantages compared to the existing recruitment systems. Future research directions have also been identified and advocated.

description: A consistent approach for an exhaustive solution of the problem of propagation of light rays in the field of gravitational waves emitted by a localized source of gravitational radiation is developed in the first post-Minkowskian and quadrupole approximation of General Relativity. We demonstrate that the equations of light propagation in the retarded gravitational field of an arbitrary localized source emitting quadrupolar gravitational waves can be integrated exactly. The influence of the gravitational field on the light propagation is examined not only in the wave zone but also in cases when light passes through the intermediate and near zones of the source. Explicit analytic expressions for light deflection and integrated time delay (Shapiro effect) are obtained accounting for all possible retardation effects and arbitrary relative locations of the source of gravitational waves, that of light rays, and the observer. It is shown that the ADM and harmonic gauge conditions can both be satisfied simultaneously outside the source of gravitational waves. Their use drastically simplifies the integration of light propagation equations and those for the motion of light source and observer in the field of the source of gravitational waves, leading to the unique interpretation of observable effects. The two limiting cases of small and large values of impact parameter are elaborated in more detail. Explicit expressions for Shapiro effect and deflection angle are obtained in terms of the transverse-traceless part of the space-space components of the metric tensor. We also discuss the relevance of the developed formalism for interpretation of radio interferometric and timing observations, as well as for data processing algorithms for future gravitational wave detectors.

We focus on the degeneracy and valence dependence in the limit of a large Coulomb interaction. For integer valence, it is found that the degeneracy increases the width of the photoemission spectrum and it reduces the contribution from the charge degrees of freedom to the specific heat. A deviation from integer valence reduces the width of the photoemission spectrum.

description: For a semisimple Lie group $G$ with parabolic subgroups $Q\subset P\subset G$, we associate to a parabolic geometry of type $(G,P)$ on a smooth manifold $N$ the correspondence space $\Cal CN$, which is the total space of a fiber bundle over $N$ with fiber a generalized flag manifold, and construct a canonical parabolic geometry of type $(G,Q)$ on $\Cal CN$. Conversely, for a parabolic geometry of type $(G,Q)$ on a smooth manifold $M$, we construct a distribution corresponding to $P$, and find the exact conditions for its integrability. If these conditions are satisfied, then we define the twistor space $N$ as a local leaf space of the corresponding foliation. We find equivalent conditions for the existence of a parabolic geometry of type $(G,P)$ on the twistor space $N$ such that $M$ is locally isomorphic to the correspondence space $\Cal CN$, thus obtaining a complete local characterization of correspondence spaces. We show that all these constructions preserve the subclass of normal parabolic geometries (which are determined by some underlying geometric structure) and that in the regular normal case, all characterizations can be expressed in terms of the harmonic curvature of the Cartan connection, which is easier to handle. Several examples and applications are discussed.

VITAM PRO LAUDE PACISCI: YOUTH AND AGE IN THE FUNERAL GAMES OF ANCHISES AND THEIR IMPLICATIONS

Year: 2024

description: It is only in recent decades that Aen. 5 has begun to garner due attention for its role as a narrative and thematic fulcrum point, transitioning between the former and latter halves of the epic as well as between Trojan past and Roman future. This paper draws attention to a central theme running throughout Aen. 5: disparity between the book’s younger and older characters. It reveals Vergil’s repeated characterization of his younger characters as overzealous to prove themselves, while ill-matched in capability to the elder figures that they are all too quick to disdain or ignore. In so doing, this paper demonstrates that Vergil adapts his theme from a Homeric precedent, carefully altering details garnered from the Iliad’s depiction of an exemplary ideal of youthful respect towards elders to paint a consistent picture of a younger generation of Trojans who are heedless towards their elders and forefathers in their own eager pursuit of personal glory. This paper will further illustrate how this running theme recurs with tragic consequences in the epic’s latter half, when it is transferred from the benign world of athletic competition to the deadly theater of war in Latium. It concludes that Vergil has imbued his Aeneid with a running message of the dangers of too quickly discarding the consul of elder generations.

The analytical results for qubit and qutrit systems with two or three measurement settings are explicitly derived, with detailed examples showing that they outperform the existing bounds. The case with the presence of quantum memory is also investigated.

Based on point-wise quadrant analysis, the turbulent components of the transport of momentum and scalars are found to be similar in general, albeit with increasing dissimilarity for roughnesses with low frontal blockage. However, strong dissimilarity is noted between the dispersive momentum and scalar fluxes, especially below the top of the roughness elements. In general, turbulence is found to transport momentum more efficiently than scalars, while the reverse applies for the dispersive contributions. The effects of varying surface geometries, measured by the frontal density, can be pronounced on both turbulent and dispersive fluxes. Increasing frontal density induces a general transition in the flow from a rough boundary-layer type to a mixed-layer-like type. This transition results in an increase in the efficiency of turbulent momentum transport, but the reverse occurs for scalars due to reduced contributions from large scale motions in the roughness sublayers. This study highlights the need for distinct parameterizations of the dispersive scalar fluxes and the importance of considering the contrasts between momentum and scalar transport for turbulent flows over very rough surfaces.

A Metagenomics Workflow to Assess the Genetic Diversity of the Vibrio-Squid Symbiosis
Creators: name: Shook, Rikki
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2024

description: Host-colonization sites containing low-diversity microbial populations present a unique problem when applying metagenomics approaches. For example, how does one extract information such as the number of unique genotypes and relative abundance of symbiotically relevant genes? The light organ of the Hawaiian bobtail squid (Euprymna scolopes) is colonized by multiple strains of a single, bioluminescent bacterial species, Vibrio fischeri. The strain-level diversity of V. fischeri is useful in competition for host-colonization sites, and greatly impacts the outcome of colonization experiments of the squid host. Thus, applying metagenomics to this symbiosis model system is critical to understanding the genetic factors required to compete for and colonize the host, as well as analyzing the eco-evolutionary dynamics of symbiotic associations.  This project develops a method for assessing the abundance of strains that have a gene of interest and estimate strain richness within the E. scolopes light organ. Synthetic “mock” communities with mixed proportions of six V. fischeri strains were created to test a bioinformatics pipeline optimized for use with closely related strains and then applied to a wild light organ community. Ultimately, the resulting bioinformatic workflow is adaptable and capable of determining the proportion of genomes in the sample that have genes of interest, including the type VI secretion system interbacterial weapon, and provides potential methods to determine strain richness in a light organ metagenome.

A NEW ERA:  AN ANALYSIS OF ATHLETE ENDORSEMENTS FOLLOWING THE ENACTMENT OF NAME, IMAGE, AND LIKENESS LEGISLATION
Creators: name: Pulliam, Erin
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2024

description: The purpose of the study was to examine prevalence, engagement, and fan sentiment toward the professional and collegiate female and male athlete endorsement posts on official Instagram accounts of Nike, Under Armour, and Adidas between July 1, 2021, when NIL legislation went into effect, to July 1, 2023. This study contributes to the existing literature on NIL, particularly concerning fan responses to athlete endorsements. Data was collected through content analysis and sentiment analysis to examine each athlete endorsement and its fan response. The research suggests that college athletes represent a small portion of athlete endorsements for large brands, however, fans are responding positively to college athlete endorsements, favoring male college athlete endorsements over female college athlete endorsements.
On induced CPT-odd Chern-Simons terms in 3+1 effective action

description: This paper was originally designated as Comment to the paper by R. Jackiw and V. Alan Kostelecky (hep-ph/9901358). We provide an example of the fermionic system, the superfluid 3He-A, in which the CPT-odd Chern-Simons terms in the effective action are unambiguously induced by chiral fermions. In this system the Lorentz and gauge invariances both are violated at high energy, but the behavior of the system beyond the cut-off is known. This allows us to construct the CPT-odd action, which combines the conventional 3+1 Chern-Simons term and the mixed axial-gravitational Chern-Simons term discussed in hep-ph/9905460. The influence of Chern-Simons term on the dynamics of the effective gauge field has been experimentally observed in rotating 3He-A.

description: Numerical studies performed with a primitive equation model on two-dimensional sinusoidal hills show that the local velocity profiles behave logarithmically to a very good approximation, from a distance from the surface of the order of the maximum hill height almost up to the top of the boundary layer. This behavior is well known for flows above homogeneous and flat topographies (``law-of-the-wall'') and, more recently, investigated with respect to the large-scale (``asymptotic'') averaged flows above complex topography. Furthermore, this new-found local generalized law-of-the-wall involves effective parameters showing a smooth dependence on the position along the underlying topography. This dependence is similar to the topography itself, while this property does not absolutely hold for the underlying flow, nearest to the hill surface.
