description: Radiation therapy in patients with head and neck cancer has a toxic effect on mucosa, the soft tissue in and around the mouth. Hence mucositis is a serious common side effect and is a condition characterized by pain and inflammation of the surface of the mucosa. Although the mucosa recovers during breaks of and following the radiotherapy course the recovery will depend on the type of tissue involved and on its location. We present a novel flexible multivariate random effects proportional odds model which takes account of the longitudinal course of oral mucositis at different mouth sites and of the radiation dosage (in terms of cumulative dose). The model is an extension of the {\em proportional odds model} which is used for ordinal response variables. Our model includes the ordinal multivariate response of the mucositis score by location, random intercepts for individuals and includes a non-linear function of cumulative radiation dose. The model allows to test whether sensitivity differs by mouth sites after having adjusted for site specific cumulative radiation dose. The model also allows to check whether and how the (non-linear) effect of site specific dose differs by site. We fit the model to longitudinal patient data from a prospective observation and find that after adjusting for cumulative dose, upper, lower lips and mouth floor are associated with the lowest mucositis scores and hard and soft palate are associated with the highest mucositis scores. This implies the possibility that tissues at different mouth locations differ in their sensitivity to the toxic effect of radiation. We also find that cumulative dose followed by mouth site are the strongest predictors of mucositis, and the effects of age and gender are negligible.

description: We report on experimental study of the exciton-polariton emission (PE) polarization noise below and above the polariton lasing threshold under continuous wave nonresonant excitation. The experiments were performed with a high-Q graded 5λ/2 GaAs/AlGaAs microcavity with three quantum wells in the strong coupling regime. The PE polarization noise substantially exceeded in magnitude the shot noise level and, in the studied frequency range (up to 650 MHz), had a flat spectrum. We have found that the PE polarization noise magnitude dependence on the pump intensity showed specific features that had no analogy in power dependences of the PE intensity and intensity noise. Particularly, the linear polarization fluctuations normalized by the emission intensity showed a remarkably non-monotonic dependence on the pump power. A theoretical model describing the observed peculiarity of the PE polarization noise is proposed.

description: Optical measurements and band structure calculations are reported on 3D Dirac materials. The electronic properties associated with the Dirac cone are identified in the reflectivity spectra of Cd$_3$As$_2$ and Na$_3$Bi single crystals. In Na$_3$Bi, the plasma edge is found to be strongly temperature dependent due to thermally excited free carriers in the Dirac cone. The thermal behavior provides an estimate of the Fermi level $E_F=25$ meV and the z-axis Fermi velocity $v_z = 0.3 \text{ eV} Å$ associated with the heavy bismuth Dirac band. At high energies above the $Γ$-point Lifshitz gap energy, a frequency and temperature independent $ε_2$ indicative of Dirac cone interband transitions translates into an ab-plane Fermi velocity of $3 \text{ eV} Å$. The observed number of IR phonons rules out the $\text{P}6_3\text{/mmc}$ space group symmetry but is consistent with the $\text{P}\bar{3}\text{c}1$ candidate symmetry. A plasmaron excitation is discovered near the plasmon energy that persists over a broad range of temperature. The optical signature of the large joint density of states arising from saddle points at $Γ$ is strongly suppressed in Na$_3$Bi consistent with band structure calculations that show the dipole transition matrix elements to be weak due to the very small s-orbital character of the Dirac bands. In Cd$_3$As$_2$, a distinctive peak in reflectivity due to the logarithmic divergence in $ε_1$ expected at the onset of Dirac cone interband transitions is identified. The center frequency of the peak shifts with temperature quantitatively consistent with a linear dispersion and a carrier density of $n=1.3\times10^{17}\text{ cm}^{-3}$. The peak width gives a measure of the Fermi velocity anisotropy of $10\%$, indicating a nearly spherical Fermi surface. The lineshape gives an upper bound estimate of 7 meV for the potential fluctuation energy scale.

description: Ballistic Josephson junctions are studied in the presence of a spin-splitting field and spin-orbit coupling. A generic expression for the quasi-classical Green's function is obtained and with its help we analyze several aspects of the proximity effect between a spin-textured normal metal (N) and singlet superconductors (S). In particular, we show that the density of states may show a zero-energy peak which is a generic consequence of the spin-dependent couplings in heterostructures. In addition we also obtain the spin current and the induced magnetic moment in a SNS structure and discuss possible coherent manipulation of the magnetization which results from the coupling between the superconducting phase and the spin degree of freedom. Our theory predicts a spin accumulation at the S/N interfaces, and transverse spin currents flowing perpendicular to the junction interfaces. Some of these findings can be understood in the light of a non-Abelian electrostatics.

description: We demonstrate the creation of entangled, spin-squeezed states using a collective, or joint, measurement and real-time feedback. The pseudospin state of an ensemble of $N= 5\times 10^4$ laser-cooled $^{87}$Rb atoms is deterministically driven to a specified population state with angular resolution that is a factor of 5.5(8) [7.4(6)~dB] in variance below the standard quantum limit for unentangled atoms --- comparable to the best enhancements using only unitary evolution. Without feedback, conditioning on the outcome of the joint premeasurement, we directly observe up to 59(8) times [17.7(6)~dB] improvement in quantum phase variance relative to the standard quantum limit for $N=4\times 10^5$ atoms. This is one of the largest reported entanglement enhancements to date in any system.

description: We propose a new interpretation of the neutral and charged X, Z exotic hadron resonances. Hybridized-tetraquarks are neither purely compact tetraquark states nor bound or loosely bound molecules. The latter would require a negative or zero binding energy whose counterpart in h-tetraquarks is a positive quantity. The formation mechanism of this new class of hadrons is inspired by that of Feshbach metastable states in atomic physics. The recent claim of an exotic resonance in the Bs pi+- channel by the D0 collaboration and the negative result presented subsequently by the LHCb collaboration are understood in this scheme, together with a considerable portion of available data on X, Z particles. Considerations on a state with the same quantum numbers as the X(5568) are also made.

description: Motivated by advances in observational searches for sub-parsec supermassive black hole binaries (SBHBs) made in the past few years we develop a semi-analytic model to describe spectral emission line signatures of these systems. The goal of this study is to aid the interpretation of spectroscopic searches for binaries and help test one of the leading models of binary accretion flows in the literature: SBHB in a circumbinary disk. In this work we present the methodology and a comparison of the preliminary model with the data. We model SBHB accretion flows as a set of three accretion disks: two mini-disks that are gravitationally bound to the individual black holes and a circumbinary disk. Given a physically motivated parameter space occupied by sub-parsec SBHBs, we calculate a synthetic database of nearly 15 million broad optical emission line profiles and explore the dependence of the profile shapes on characteristic properties of SBHBs. We find that the modeled profiles show distinct statistical properties as a function of the semi-major axis, mass ratio, eccentricity of the binary, and the degree of alignment of the triple disk system. This suggests that the broad emission line profiles from SBHB systems can in principle be used to infer the distribution of these parameters and as such merit further investigation. Calculated profiles are more morphologically heterogeneous than the broad emission lines in observed SBHB candidates and we discuss improved treatment of radiative transfer effects which will allow direct statistical comparison of the two groups.

description: The ground state of an elastic interface in a disordered medium undergoes collective jumps upon variation of external parameters. These mesoscopic jumps are called shocks, or static avalanches. Submitting the interface to a parabolic potential centered at $w$, we study the avalanches which occur as $w$ is varied. We are interested in the correlations between the avalanche sizes $S_1$ and $S_2$ occurring at positions $w_1$ and $w_2$. Using the Functional Renormalization Group (FRG), we show that correlations exist for realistic interface models below their upper critical dimension. Notably, the connected moment $ \langle S_1 S_2 \rangle^c$ is up to a prefactor exactly the renormalized disorder correlator, itself a function of $|w_2-w_1|$. The latter is the universal function at the center of the FRG; hence correlations between shocks are universal as well. All moments and the full joint probability distribution are computed to first non-trivial order in an $ε$-expansion below the upper critical dimension. To quantify the local nature of the coupling between avalanches, we calculate the correlations of their local jumps. We finally test our predictions against simulations of a particle in random-bond and random-force disorder, with surprisingly good agreement.

The lattice structure at the boundary is generated by introducing a higher-derivative interaction term between a U(1) gauge field and a scalar field. We solve the equations of motion below the critical temperature at which the lattice forms, and analyze the change in the Fermi surface due to the lattice. The fermion band structure is found to exhibit a band gap due to lattice effects.

description: Metastasis is a process of cell migration that can be collective and guided by chemical cues. Viewing metastasis in this way, as a physical phenomenon, allows one to draw upon insights from other studies of collective sensing and migration in cell biology. Here we review recent progress in the study of cell sensing and migration as collective phenomena, including in the context of metastatic cells. We describe simple physical models that yield the limits to the precision of cell sensing, and we review experimental evidence that cells operate near these limits. Models of collective migration are surveyed in order understand how collective metastatic invasion can occur. We conclude by contrasting cells' sensory abilities with their sensitivity to drugs, and suggesting potential alternatives to cell-death-based cancer therapies.

A CRITICAL ANALYSIS OF ASIAN INTERNATIONAL STUDENT EXPERIENCES IN THE U.S.

Publisher: name: Purdue University Graduate School
Year: 2023
Subjects: Counselling psychology

description: The purpose of the first paper is to serve as a critical review of the international student research. Particularly, the paper will explore current barriers in international student research specifically for Asian international students. The paper will use three frameworks for the critical review: neo-racism, critical race theory, and postcolonial theory and suggest three main barriers in international student research because of this: homogenization, overemphasis on individual factors, and the impact of stereotypes present about Asians in the U.S. Based on the frameworks used for critical review and the identified barriers, the paper will explore systemic racism in the experiences of Asian international trainees and suggest recommendations to support trainees in counseling psychology. The study within the second paper explored the experiences of neo-racism for 13 Asian international doctoral student participants at Purdue University using qualitative thematic analysis. The study demonstrated a wide variety of experiences with racism, including interpersonal racism and the impact of racism that participants viewed as occurring to other Asian and Asian international students in the U.S. Results indicated that participants’ experiences of neo-racism were different based on social identities, language abilities, and nationality. The study proposes implications of these experiences, including ways higher education institutions can better support doctoral students during this sociopolitical time.

description: In this paper we study "discrete polynomial blending," a term used to define a certain discretized version of curve blending whereby one approximates from the "sum of tensor product polynomial spaces" over certain grids. Our strategy is to combine the theory of Boolean Sum methods with dual bases connected to the Bernstein basis to construct a new quasi-interpolant for discrete blending. Our blended element has geometric properties similar to that of the Bernstein-Bézier tensor product surface patch, and rates of approximation that are comparable with those obtained in tensor product polynomial approximation.

The proof is by elementary arguments, using the extension of the convolution method for arithmetic functions of several variables, starting with the observation that given a multiplicative function $f$, the function of $k$ variables $f([n_1,\ldots,n_k])$ is multiplicative.

description: Research ethics is integral to the entire process of knowledge production: from conceptualising and designing a research project and gathering, analysing and managing data, to writing and other forms of representation and engagement. Yet, there is often a lack of attention given to research ethics pedagogy and praxis in various academic institutions. With a focus on research ethics in volatile contexts, this special issue aims to provide various perspectives on research ethics from scholars positioned within a particular discipline, such as anthropology, political science, history, sociology and area studies, among others, as well as those with an inter- or transdisciplinary perspective. Drawing from concrete research experiences and how they have dealt with ethical dilemmas as well as critical reflection and framing of research ethics, the contributors offer ways to think through the relationships between research ethics, power, violence, inequalities, institutions and pedagogy in various volatile research contexts and institutional frameworks.

Στην διαδικασία της βυνοποίησης, η βύνη απελευθερώνει φυσικά ένζυμα που χρησιμοποιούνται για να μετατρέψουν το άμυλο σε σάκχαρα. Τα σάκχαρα αυτά, κατά τη ζύμωση, καταναλώνονται και μεταβολίζονται από τις ζύμες σε αλκοόλη και διοξείδιο του άνθρακα. Συγκεκριμένα, στο γλεύκος μπύρας υπάρχει μαλτόζη σε ποσοστό 50% των υδατανθράκων του γλεύκους, μαλτοτριόζη 18%, γλυκόζη 10%, σακχαρόζη 8% και φρουκτόζη 2%, ενώ υπάρχουν και δεξτρίνες που καταλαμβάνουν το 12% των εναπομείναντων υδατανθράκων.

Οι δύο αυτές μέθοδοι βασίζονται στην ιδιότητα των αναγόντων σακχάρων να οξειδώνονται κατά την αντίδραση με διάλυμα θειικού χαλκού. Η μέθοδος Luff φάνηκε ότι λειτουργεί για τον προσδιορισμό της γλυκόζης, της φρουκτόζης και της σακχαρόζης, ενώ για την μαλτόζη οι τιμές δεν ήταν αναμενόμενες. Ομοίως, η μέθοδος Lane – Eynon φάνηκε ότι λειτουργεί για τα ίδια σάκχαρα, ενώ για τη μαλτόζη τα αποτελέσματα δεν ήταν ικανοποιητικά. Συγκρίνοντας και τις δύο μεθόδους, συμπεραίνεται ότι η μέθοδος Luff και Lane – Eynon δεν μπορούν να χρησιμοποιηθούν για να προσδιορίσουν τα ανάγοντα σάκχαρα στη μπύρα καθώς όπως αποδείχθηκε δεν λειτουργούν σε υδατικά διαλύματα.
STRONG ELECTRON CORRELATION FROM PARTITION DENSITY FUNCTIONAL THEORY
Creators: name: Shi, Yi
Publisher: name: Purdue University Graduate School

Subjects: Theoretical quantum chemistry

description: Despite the unprecedented success achieved by Kohn-Sham density functional theory (KS-DFT) in the past few decades, the standard approximations used for the KS exchange-correlation functional typically lead to unacceptably large errors when applied to strongly-correlated electronic systems. Partition-DFT (P-DFT) is a formally exact reformulation of KS-DFT in which the ground-state density and energy of a system are obtained through self-consistent calculations on isolated fragments, with a partition energy introduced to account for the inter-fragment interactions. The unique advantage of this partitioning scheme lies in the fact that it adopts the electron density of fragments as the main variable, in place of the density of the entire system in KS-DFT, so that novel approximations can be constructed in terms of fragment properties. With a simple overlap approximation (OA) of the partition energy proposed for binary-partitioned systems, P-DFT is able to rectify the static correlation error caused by standard density functional approximations for strongly-correlated diatomic molecules. In this work, we first implement P-DFT on a one-dimensional (1D) real-space grid and calculate the ground-state energy and density of a series of 1D hydrogen chains using the local density approximation (LDA) as the density functional approximation for fragments. We then propose the generalized overlap approximation (GOA) and the corrected generalized overlap approximation (cGOA), which extends the applicability of OA to systems partitioned into more than two fragments. Combining LDA with cGOA leads to quantitatively correct dissociation curves of hydrogen chains. The static correlation error of LDA is suppressed by cGOA in the strongly-correlation regime when the calculations are performed in a spin-restricted manner, i.e., without the spin symmetry breaking. Additionally, GOA induces an improvement of the ground-state density upon LDA results, and hence helps P-DFT provide a better description of the density dimerization in hydrogen chains.

description: Ambipolar carbon nanotube based field-effect transistors (AP-CNFETs) exhibit unique electrical characteristics, such as tri-state operation and bi-directionality, enabling systems with complex and reconfigurable computing. In this paper, AP-CNFETs are used to design a mixed-signal machine learning logistic regression classifier. The classifier is designed in SPICE with feature size of 15 nm and operates at 250 MHz. The system is demonstrated in SPICE based on MNIST digit dataset, yielding 90% accuracy and no accuracy degradation as compared with the classification of this dataset in Python. The system also exhibits lower power consumption and smaller physical size as compared with the state-of-the-art CMOS and memristor based mixed-signal classifiers.

description: In this work, phase diagrams of a modified two-mode phase-field crystal (PFC) that show two-dimensional (2D) and three-dimensional (3D) crystallographic structures were determined by utilizing a free energy minimization method. In this study the modified two-mode PFC model (presented by E. Asadi and M. Asle Zaeem, Comput. Mater. Sci. 2015) was used, in which the free energy can be exactly minimized in each stable crystal structure allowing calculation of accurate phase diagrams for two-mode PFC models. Different crystal structures, such as square, triangle, body-centered cubic (bcc), face-centered cubic (fcc), and stripe lattice structures as well as their coexistence regions were considered in the calculations. The model parameters were discussed to calculate phase diagrams that can be used as a guideline by other researchers for studying solidification and solid state phase transformation using two-mode PFC model.

Subjects: International Live Conference on Stress, Anxiety, and Depression

description: Abstract:
 Multiple expectations and meeting various challenges on a day-to-day basis, emerging adults are found to report varied psychological and mental health issues including depression, anxiety, panic attacks, low self-confidence, and poor well-being. More specifically post pandemic when most of the youth were under lockdown finding it difficult to bounce back to the new normal. Considering this, the present study has been planned to establish the relationship among various aspects of self-confidence (i.e. general self-confidence, physical appearance self- confidence, academic self-confidence and public-speaking self-confidence), negative mood affect (anxiety, stress and depression) and perceived well-being (psychological and physical) among emerging adults by using correlational research design. To accomplish the objectives, standardized tools pertaining to the same have been administered on a sample of 200 participants based on specific inclusion and exclusion criteria. Data collection is going on and will be subjected to appropriate statistical analysis including descriptive statistics followed by correlation and linear regression analysis. Final statistical outcomes will be interpreted in the light of Indian socio-cultural context.

description: We searched for an X-ray line at energies around 3.5 keV in deep, ~1.6 Msec XMM-Newton observations of the dwarf spheroidal galaxy Draco. No line was found in either the MOS or the PN detectors. The data in this energy range are completely consistent with a single, unfolded power law modeling the particle background, which dominates at these energies, plus instrumental lines; the addition of a ~3.5 keV line feature gives no improvement to the fit. The corresponding upper limit on the line flux rules out a dark matter decay origin for the 3.5 keV line found in observations of clusters of galaxies and in the Galactic Center at greater than 99% C.L..

Excited-state quantum phase transitions in many-body systems with infinite-range interaction: Localization, dynamics, and bifurcation

description: Excited state quantum phase transitions (ESQPTs) are generalizations of quantum phase transitions (QPTs) to excited levels. They are associated with local divergences in the density of states. Here, we investigate how the presence of an ESQPT can be detected from the analysis of the structure of the Hamiltonian matrix, the level of localization of the eigenstates, the onset of bifurcation, and the speed of the system evolution. Our findings are illustrated for a Hamiltonian with infinite-range Ising interaction in a transverse field. This is a version of the Lipkin-Meshkov-Glick (LMG) model and the limiting case of the one-dimensional spin-1/2 system with tunable interactions realized with ion traps. From our studies for the dynamics, we uncover similarities between the LMG and the noninteracting XX models.
