description: Precalculus and single-variable calculus courses are a critical early juncture for the success of science, technology, engineering, and mathematics (STEM) students in the United States (US). The default course structure is often a required three-term sequence of precalculus, differential calculus, and integral calculus. In this paper we analyse variations to this structure, the nature of such variations, their frequency across US universities, and how instructional approach and performance rates in those variations compare to those in the standard course offerings. We found that course variations are relatively common, and are primarily targeting students with more math preparation, less math preparation, or those majoring in a specific discipline. We found that for less prepared students, who are typically at the highest risk of failing, course variations resulted in similar passing rates, essentially levelling the playing field for these students. Although we had conjectured that disruptions to the standard offering would allow for greater use of active learning strategies, no such difference was observed. Ways in which these course variations can redress systemic educational inequalities, opportunities for design improvement, and future research are discussed.

description: We report a computational 3D microscopy technique, termed Fourier ptychographic diffraction tomography (FPDT), that iteratively stitches together numerous variably illuminated, low-resolution images acquired with a low-numerical aperture (NA) objective in 3D Fourier space to create a wide field-of-view (FOV), high-resolution, depth-resolved complex refractive index (RI) image across large volumes. Unlike conventional optical diffraction tomography (ODT) approaches that rely on controlled bright-field illumination, holographic phase measurement, and high-NA objective detection, FPDT employs tomographic RI reconstruction from low-NA intensity-only measurements. In addition, FPDT incorporates high-angle dark-field illuminations beyond the NA of the objective, significantly expanding the accessible object frequency. With FPDT, we present the highest-throughput ODT results with 390nm lateral resolution and 899nm axial resolution across a 10X FOV of 1.77mm2 and a depth of focus of ~20μm. Billion-voxel 3D tomographic imaging results of biological samples establish FPDT as a powerful non-invasive and label-free tool for high-throughput 3D microscopy applications.

description: I present recent results on the theory of QCD matter production in high energy heavy ion collisions and on the interactions of heavy quarks in such environment. The centrality and rapidity dependence of hadron production is evaluated in semi--classical approach. The energy loss of heavy quarks in matter is computed. The heavy--to--light meson ratio (e.g., D/pion) at moderate transverse momenta is demonstrated to be both sensitive to the density of color charges in the medium and infrared stable.

description: We present Monte Carlo reconstruction, a new method for ``inverting'' observational data to constrain the form of the scalar field potential responsible for inflation. This stochastic technique is based on the flow equation formalism and has distinct advantages over reconstruction methods based on a Taylor expansion of the potential. The primary ansatz required for Monte Carlo reconstruction is simply that inflation is driven by a single scalar field. We also require a very mild slow roll constraint, which can be made arbitrarily weak since Monte Carlo reconstruction is implemented at arbitrary order in the slow roll expansion. While our method cannot evade fundamental limits on the accuracy of reconstruction, it can be simply and consistently applied to poor data sets, and it takes advantage of the attractor properties of single-field inflation models to constrain the potential outside the small region directly probed by observations. We show examples of Monte Carlo reconstruction for data sets similar to that expected from the Planck satellite, and for a hypothetical measurement with a factor of five better parameter discrimination than Planck.

description: One major function of education is to train student for them to be qualified to their target profession in the future (Biesta, 2009). High stake testing is one of the ultimate measures of competency in school and measuring academic achievement. Due to the applied standard education, many students were having hard time to pass their exams and subjects. Hence, private tutoring was usually applied to the low achiever students to help them cope up with their peers. Private tutoring is one form of shadow education (Mori & Baker, 2010). On a licensure examination preparation, shadow education is also being applied by the use of inhouse review and outside review centers. The PHINMA-SJC institution has their own strategy in preparing students for board exam. It is conducting one form of shadow education where the participants are still in its 4th year level. Hence, the aim of this research is to analyze the perceptions of the Medical Technology students to the shadow education applied. It employs qualitative descriptive research design in relating the responses of the students to their experiences, expectation, challenges and coping mechanism to the shadow education applied. Eleven (11) students agreed to be interviewed via open-ended survey method enrolled in 1st semester 2018-2019. The outcomes of this study evidenced that the students had more negative experience before the shadow education while during and after the shadow education, their experience becomes positive towards the shadow education. Furthermore, the students have more positive expectation, challenges and coping mechanism outlook to the shadow education. Specifically, the main challenge faced by the students was the assessment exams given. While their expectation becomes their coping mechanism to pass the shadow education. Hence, the resiliency from challenging task is significant to prepare the students for licensure exam.

description: Somatic mutations commonly occur in hematopoietic stem cells (HSCs). Some mutant clones outgrow through clonal hematopoiesis (CH) and produce mutated immune progenies shaping host immunity. Individuals with CH are asymptomatic but have an increased risk of developing leukemia, cardiovascular and pulmonary inflammatory diseases, and severe infections. Using genetic engineering of human HSCs (hHSCs) and transplantation in immunodeficient mice, we describe how a commonly mutated gene in CH, TET2, affects human neutrophil development and function. TET2 loss in hHSCs produce a distinct neutrophil heterogeneity in bone marrow and peripheral tissues by increasing the repopulating capacity of neutrophil progenitors and giving rise to low-granule neutrophils. Human neutrophils that inherited TET2 mutations mount exacerbated inflammatory responses and have more condensed chromatin, which correlates with compact neutrophil extracellular trap (NET) production. We expose here physiological abnormalities that may inform future strategies to detect TET2-CH and prevent NET-mediated pathologies associated with CH.

description: In this work, we use the thin-layer quantization procedure to study the physical implications due to curvature effects on a quantum dot in the presence of an external magnetic field. Among the various physical implications due to the curvature of the system, we can mention the absence of the $m=0$ state is the most relevant one. The absence of it affects the Fermi energy and consequently the thermodynamic properties of the system. In the absence of magnetic fields, we verify that the rotational symmetry in the lateral confinement is preserved in the electronic states of the system and its degeneracy with respect to the harmonicity of the confining potential is broken. In the presence of a magnetic field, however, the energies of the electronic states in a quantum dot with a curvature are greater than those obtained for a quantum dot in a flat space, and the profile of degeneracy changes when the field is varied. We show that the curvature of the surface modifies the number of subbands occupied in the Fermi energy. In the study of both magnetization and persistent currents, we observe that Aharonov-Bohm-type (AB-type) oscillations are present, whereas de Haas-van Alphen-type (dHvA) oscillations are not well defined.

description: We investigate holographic fermions in uni-directional striped phases, where the breaking of translational invariance can be generated either spontaneously or explicitly. We solve the Dirac equation for a probe fermion in the associated background geometry. When the spatial modulation effect becomes sufficiently strong, we see a spectral weight suppression whenever the Fermi surface is larger than the first Brillouin zone. This leads to the gradual disappearance of the Fermi surface along the symmetry breaking direction, in all of the cases we have examined. This effect appears to be a generic consequence of strong inhomogeneities, independently of whether translational invariance is broken spontaneously or explicitly. The resulting Fermi surface is segmented and has features reminiscent of Fermi arcs.

description: Combining molecular dynamics and Monte Carlo simulation we study defect structures around an elongated colloidal particle embedded in a nematic liquid crystal host. By studying nematic ordering near the particle and the disclination core region we are able to examine the defect core structure and the difference between two simulation techniques. In addition, we also study the torque on a particle tilted with respect to the director, and modification of this torque when the particle is close to the cell wall.

description: With the rapid growth of the data volume and the fast increasing of the computational model complexity in the scenario of cloud computing, it becomes an important topic that how to handle users' requests by scheduling computational jobs and assigning the resources in data center. In order to have a better perception of the computing jobs and their requests of resources, we analyze its characteristics and focus on the prediction and classification of the computing jobs with some machine learning approaches. Specifically, we apply LSTM neural network to predict the arrival of the jobs and the aggregated requests for computing resources. Then we evaluate it on Google Cluster dataset and it shows that the accuracy has been improved compared to the current existing methods. Additionally, to have a better understanding of the computing jobs, we use an unsupervised hierarchical clustering algorithm, BIRCH, to make classification and get some interpretability of our results in the computing centers.

description: The electro-discharge (ED) drilling of precision boreholes in difficult-to-machine materials, particularly with respect to the cost-effectiveness of the overall process, is still a challenge. Flushing is one key factor for the precise machining of boreholes, especially with high aspect ratios. Therefore, the influence of internal and external flushing geometries for six types of brass tool electrodes with a diameter of 3 mm with and without a helical groove was analyzed experimentally and numerically. Using this helical external flushing channel, drilling experiments in X170CrVMo18-3-1 (Elmax Superclean) with an aspect ratio of five revealed a material removal rate (MRR) that was increased by 112% compared with a rod electrode, increased by 28% for a single-channel tool electrode and decreased by 8% for a multi-channel tool electrode. Signal analyses complemented these findings and highlighted correlations between classified discharge event types and the experimental target parameters. Amongst others, it was verified that the arcing frequency ratio drove the electrode wear rate and the beneficial frequency ratio correlated with the MRR and the surface roughness Ra. Sophisticated 3D computational fluid dynamics (CFD) models of the liquid phase were introduced and evaluated in great detail to demonstrate the validity and further elucidate the effect of the external flushing channel on the evacuation capability of debris and gas bubbles. The presented methods and models were found to be suitable for obtaining in-depth knowledge about the flushing conditions in the ED drilling working gap.
Closed Textile Cycle for Communally Collected Postconsumer Mattress Covers in Europe

description: Up to 30 million mattresses are disposed of each year in the EU, with the majority going to landfills and incinerators. A variety of materials, including a significant amount of textiles, are combined to create mattresses. Hence, the disposal of postconsumer (PC) mattresses results in a significant loss of recycling potential.

Via an applied case study, the research project ECOMADE examined the possibilities for recycling of communally collected PC mattress covers throughout Europe. In the case study, 500 kg of discarded PC mattress covers were gathered, dismantled, mechanically recycled, and turned into nonwovens, knitwear, and woven products. Nonwovens include 50%–100% tear fibers from PC mattress covers, while yarns contain 50%–70% of these fibers. Fresh R-PET fibers, PET/Co-PET Bico fibers, or cotton fibers were utilized for the blend, depending on the intended usage. Together with the industry, the nonwoven properties (thermobonding and/or needle-punching, 96–354 gsm) were assessed and put to the test on their production lines. Due to their low tensile strength, the yarns (open-end, Nm 18–40) were only tested on handlooms and hand knitting machines.

The findings demonstrate that a high-quality closed loop using mechanically recycled fibers from PC mattress covers for nonwovens is both reasonable and practical from an ecological standpoint. The use of the tear fibers in yarns makes less sense because the processability and durability are not sufficient for industrial use. There are still unanswered problems in terms of more efficient mattress cover processing, guarantee of hygiene, appropriate recycled fiber content, and affordability.

description: The isolated binary evolution model for merging neutron stars (NSs) involves processes such as mass transfer, common-envelope evolution, and natal kicks, all of which are poorly understood. Also, the predicted NS-NS merger rates are typically lower than the rates inferred from the LIGO GW170817 event. Here, we investigate merger rates of NS and black hole (BH)-NS binaries in hierarchical triple-star systems. In such systems, the tertiary can induce Lidov-Kozai (LK) oscillations in the inner binary, accelerating its coalescence, and potentially enhancing compact object merger rates. However, since compact objects originate from massive stars, the prior evolution should also be taken into account. Natal kicks, in particular, could significantly reduce the rates by unbinding the tertiary before it can affect the inner binary through LK evolution. We carry out simulations of massive triples taking into account stellar evolution starting from the main sequence, secular and tidal evolution, and the effects of supernovae. For large NS birth kicks (σ_k = 265 km/s), we find that the triple NS-NS merger rate (several hundred Gpc^{-3} yr^{-1}) is lower by a factor of ~2-3 than the binary rate, but for no kicks (σ_k = 0 km/s), the triple rate (several thousand Gpc^{-3} yr^{-1}) is comparable to the binary rate. Our results indicate that a significant fraction of NS-NS mergers could originate from triples if a substantial portion of the NS population is born with low kick velocities, as indicated by other work. However, uncertainties and open questions remain because of our simplifying assumption of dynamical decoupling after inner binary interaction has been triggered.

description: An abiding concern for the responsible use of data is nothing new for those of us among the ranks of data professionals. Whether from the perspective of research, education, commerce, or policy, careful consideration of data ethics is an important aspect of our work. The recent increase in the accessibility and prevalence of “generative AI” technology adds a new dimension to the digital landscape and a new level of difficulty for would-be facilitators of information literacy. Briefly, generative AI uses complex, impenetrable statistical models to produce novel combinations of text or images in response to user prompts. The best-known example may be ChatGPT, which can in mere seconds write a poem in the style of Edgar Allen Poe, a tailored marketing pitch, or a research paper that may or may not be accurate. What does this mean for us?

 Von Galium mollugo im engeren Sinn sind aus dem Bundesland Salzburg bisher nur sehr wenige Funde bekannt (WITTMANN et al. 1987). Die Art ist aber auf jeden Fall beträchtlich seltener als das nahe verwandte Galium album, das vor allem in Fettwiesen vorkommt. Wie aus den oben genannten Funden hervorgeht, besiedelt Galium mollugo in Salzburg vor allem zwei Lebensräume. Zum einen sind es Au-Bereiche, die auch im lichten Waldbestand liegen, aber auch auf Streuwiesen übergreifen können. Andererseits gibt es aber auch mehrere Vorkommen in hochmontanen Waldrandbereichen und Grasfluren. Genau in dieses Bild passen auch die in WITTMANN & PILSL (1997) veröffentlichten Funde.

Validating the Validation: Reanalyzing a large-scale comparison of Deep Learning and Machine Learning models for bioactivity prediction

description: Machine learning methods may have the potential to significantly accelerate drug discovery. However, the increasing rate of new methodological approaches being published in the literature raises the fundamental question of how models should be benchmarked and validated. We reanalyze the data generated by a recently published large-scale comparison of machine learning models for bioactivity prediction and arrive at a somewhat different conclusion. We show that the performance of support vector machines is competitive with that of deep learning methods. Additionally, using a series of numerical experiments, we question the relevance of area under the receiver operating characteristic curve as a metric in virtual screening, and instead suggest that area under the precision-recall curve should be used in conjunction with the receiver operating characteristic. Our numerical experiments also highlight challenges in estimating the uncertainty in model performance via scaffold-split nested cross validation.

description: Quantum chromodynamics (QCD) at sufficiently high density is expected to undergo a chiral phase transition. Understanding such a transition is of particular importance for neutron star or quark star physics. In Lagrangian SU(3) lattice gauge theory, the standard approach breaks down at large chemical potential $μ$, due to the complex action problem. The Hamiltonian formulation of lattice QCD doesn't encounter such a problem. In a previous work, we developed a Hamiltonian approach at finite chemical potential $μ$ and obtained reasonable results in the strong coupling regime. In this paper, we extend the previous work to Wilson fermions. We study the chiral behavior and calculate the vacuum energy, chiral condensate and quark number density, as well as the masses of light hadrons. There is a first order chiral phase transition at zero temperature.

description: The proliferation of Internet of Things (IoT) is reshaping our lifestyle. With IoT sensors and devices communicating with each other via the Internet, people can customize automation rules to meet their needs. Unless carefully defined, however, such rules can easily become points of security failure as the number of devices and complexity of rules increase. Device owners may end up unintentionally providing access or revealing private information to unauthorized entities due to complex chain reactions among devices. Prior work on trigger-action programming either focuses on conflict resolution or usability issues, or fails to accurately and efficiently detect such attack chains. This paper explores security vulnerabilities when users have the freedom to customize automation rules using trigger-action programming. We define two broad classes of attack--privilege escalation and privacy leakage--and present a practical model-checking-based system called SAFECHAIN that detects hidden attack chains exploiting the combination of rules. Built upon existing model-checking techniques, SAFECHAIN identifies attack chains by modeling the IoT ecosystem as a Finite State Machine. To improve practicability, SAFECHAIN avoids the need to accurately model an environment by frequently re-checking the automation rules given the current states, and employs rule-aware optimizations to further reduce overhead. Our comparative analysis shows that SAFECHAIN can efficiently and accurately identify attack chains, and our prototype implementation of SAFECHAIN can verify 100 rules in less than one second with no false positives.

description: We present our implementation autoCAS for fully automated multi-configurational calculations, which we also make available free of charge on our webpages. The graphical user interface of autoCAS connects a general electronic structure program with a density matrix renormalization group program to carry out our recently introduced automated active space selection protocol for multi-configurational calculations [J. Chem. Theory Comput., 2016, 12, 1760]. Next to this active space selection, autoCAS carries out several steps of multi-configurational calculations so that only a minimal input is required to start them, comparable to that of a standard Kohn-Sham density functional theory calculation, so that black-box multi-configurational calculations become feasible. Furthermore, we introduce a new extension to the selection algorithm that facilitates automated selections for molecules with large valence orbital spaces consisting of several hundred orbitals.

description: The complex dynamic Young's modulus of ceramic Nd2-xCexCuO4 with x = 0, 0.05 and 0.20 has been measured from 1.5 to 100 K at frequencies of 1-10 kHz. In the undoped sample the modulus starts decreasing below ~20 K, instead of approaching a constant value as in a normal solid. The modulus minimum has been interpreted in terms of paraelastic contribution from the relaxation of the Nd^3+ 4f electrons between the levels of the ground state doublet, which is split by the interaction with the antiferromagnetically ordered Cu sublattice. The value of the splitting is found to be 0.34 meV, in excellent agreement with inelastic neutron scattering, infrared and specific heat experiments. With doping, the anomaly shifts to lower temperature and decreases in amplitude, consistently with a reduction of the local field from the Cu sublattice.
