description: The decay of $B^*_{s,d} \to μ^+ μ^-$~ and its impact on $B_{s,d} \to μ^+ μ^-$ is studied here. The $ μ^+ μ^-$ decay widths of vector mesons $B^*_{s,d}$ are about a factor of 700 larger than the corresponding scalar mesons $B_{s,d}$. The obtained ratio of the branching fractions $Br({B_{s,d}^*\to μ^+μ^-})/{Br({B_{s,d}\toμ^+μ^-})}$ is about $\frac{0.3 \times {\rm eV}}{{Γ(B^*_{s,d} \to B_{s,d} γ)}}$. At the same time, the hadronic contribution $B_{s,d} \to B^*_{s,d} γ\to μ^+ μ^-$ is estimated too. The relative increase of the amplitude of $B_{s,d}\to μ^+μ^-$ is about $(0.01\pm 0.006) \sqrt{\frac{{Γ(B^*_{s,d} \to B_{s,d} γ)}}{100~ {\rm eV}}}$. If we choose $Γ(B^*_{s,d} \to B_{s,d} γ)=2~$eV, the branching fractions of the vector mesons to lepton pair are $(6.2 \pm 0.6) \times 10^{-10}$ and $(1.7 \pm 0.2) \times 10^{-11}$ for $B^*_{s}$ and $B^*_{d}$ respectively. If we choose $Γ(B^*_{s,d} \to B_{s,d} γ)=200~$eV, the updated branching fractions of the scalar mesons to muon pair are $(3.78 \pm 0.25)\times 10^{-9}$ and $(1.09 \pm 0.09)\times 10^{-10}$ for $B_{s}$ and $B_{d}$ respectively. Further studies on $B^*_{s,d}$ are usefully here, including dielectron decay, two-body decay with $J/ψ$, and so on.

description: Brane tilings describe Lagrangians (vector multiplets, chiral multiplets, and the superpotential) of four dimensional $\mathcal{N}=1$ supersymmetric gauge theories. These theories, written in terms of a bipartite graph on a torus, correspond to worldvolume theories on $N$ D$3$-branes probing a toric Calabi-Yau threefold singularity. A pair of permutations compactly encapsulates the data necessary to specify a brane tiling. We show that geometric consistency for brane tilings, which ensures that the corresponding quantum field theories are well behaved, imposes constraints on the pair of permutations, restricting certain products constructed from the pair to have no one-cycles. Permutations without one-cycles are known as derangements. We illustrate this formulation of consistency with known brane tilings. Counting formulas for consistent brane tilings with an arbitrary number of chiral bifundamental fields are written down in terms of delta functions over symmetric groups.

description: Sextic polynomial oscillator is probably the best known quantum system which is partially exactly {\it alias} quasi-exactly solvable (QES), i.e., which possesses closed-form, elementary-function bound states $ψ(x)$ at certain couplings and energies. In contrast, the apparently simpler and phenomenologically more important quartic polynomial oscillator is {\em not\,} QES. A resolution of the paradox is proposed: The one-dimensional Schrödinger equation is shown QES after the analyticity-violating symmetrization $V(x)=A|x|+B x^2+C|x|^3+x^4$ of the quartic polynomial potential.

description: A density functional theory study of NbSe$_2$ single-layers in the normal non-modulated and the $3\times3$ CDW states is reported. We show that, in the single layer, the CDW barely affects the Fermi surface of the system, thus ruling out a nesting mechanism as the driving force for the modulation. The CDW stabilizes levels lying around 1.5 eV below the Fermi level within the Se-based valence band but having a substantial Nb-Nb bonding character. The absence of interlayer interactions leads to the suppression of the pancake-like portion of the bulk Fermi surface in the single-layer. We perform scanning tunneling microscopy simulations and find that the images noticeably change with the sign and magnitude of the voltage bias. The atomic corrugation of the Se sublayer induced by the modulation plays a primary role in leading to these images, but the electronic reorganization also has an important contribution. The analysis of the variation of these images with the bias voltage does not support a Fermi surface nesting mechanism for the CDW. It is also shown that underlying graphene layers (present in some of the recent experimental work) do not modify the conduction band, but do affect the shape of the valence band of NbSe$_2$ single-layers. The relevance of these results in understanding recent physical measurements for NbSe$_2$ single-layers is discussed.

description: Auger (L3M4,5M4,5) and X-ray photoionization spectra (2p, 3d) of mass-selected CuN-clusters supported by a thin natural silica layer are presented in the size range N = 8–55 atoms per cluster. The Auger spectra of all clusters are shifted to a lower kinetic energy with respect to the spectrum of the bulk. Furthermore the Auger energy decreases systematically with decreasing cluster size. The binding energies of the 2p and 3d valence states are higher than the corresponding bulk values. Using the energy of the Auger main line, the corresponding core hole peak and the centroid of the self-convoluted 3d valence band the on-site Coulomb interaction energy Udd of the two-hole final state as a function of cluster size has been determined.

description: Having in mind the well-known limitations of certain models of generalized parton distributions (GPDs), we show that the allegedly universal GPDs, describing both deeply virtual Compton scattering (DVCS) and deeply virtual meson production (DVMP) data, fail to describe measurements of deep inelastic scattering. We present a new global DVCS fit that describes reasonably the world data set, which includes now also new measurements from Hall A and CLAS collaborations. We also explicitly illustrate that Compton form factors (CFFs) cannot be unambiguously extracted from photon electroproduction measurements off unpolarized proton alone and we argue that it is more reliable to interpret such measurements in terms of certain CFF combinations, where still some care is needed in order to estimate the propagated error.

description: Mesoporous carbon nitrides, silicas and their composites have been prepared by a combined sol–gel and thermal condensation approach. Precursors for the carbon nitride (cyanamide) and silica (TEOS) are mixed and condensed simultaneously. After condensation and heat treatment it is observed that the carbon nitride and silica formed highly interpenetrating mesophases which leads either to the formation of mesoporous carbon nitride or silica after selective removal of one of the phases. Importantly, the carbon nitride preserves its graphitic stacking even in the spatial confinement introduced by the surrounding silica phase. As both precursors are liquids this approach allows convenient shaping into thin and thick films or monoliths of mesoporous carbon nitrides. Enhanced photocatalytic activity is observed for the production of hydrogen from water when these mesoporous carbon nitrides are applied as photocatalyst in comparison to the bulk, but also to other mesoporous carbon nitrides, prepared by the reported two-step, hard templating approach.

description: Let $G$ be a graph with adjacency matrix $A$. The transition matrix of $G$ relative to $A$ is defined by $H_{A}(t):=\exp{(-itA)},\;t\in\Rl$. We say that the graph $G$ admits perfect state transfer between the verteices $u$ and $v$ at $τ\in\Rl$ if the $uv$-th entry of $H_{A}(τ)$ has unit modulus. Perfect state transfer is a rare phenomena so we consider an approximation called pretty good state transfer. We find that NEPS (Non-complete Extended P-Sum) of the path on three vertices with basis containing tuples with hamming weights of both parities do not exhibit perfect state transfer. But these NEPS admit pretty good state transfer with an additional condition. Further we investigate pretty good state transfer on Cartesian product of graphs and we find that a graph can have PGST from a vertex $u$ to two different vertices $v$ and $w$.

Each individual dispersive wave can be associated to one particular dark soliton of the train, using phase-matching arguments involving higher-order dispersion and soliton velocity. For a large number of dark solitons (>10), we observe the formation of a continuum associated with the efficient emission of dispersive waves.

VOP champions innovative methods and technology – notably online public consultations – that enable the American people to play a role in the policymaking process and provide policymakers with a more accurate understanding of the views of their constituents. The Program for Public Conultation conducts policymaking simulations, which are an online process that puts citizens in the shoes of elected officials by simulating the process they go through in making policy decisions. Each simulation introduces a broader policy topic and then presents a series of modules that address a specific policy option that is currently under consideration in the current discourse. For each module, respondents: 1) receive a short briefing on a policy issue and the option or options for addressing it; 2) evaluate arguments for and against the policy options; and 3) finally, make their recommendation for what their elected officials should do.

description: Agricultural industrialization in the 21st century has presented acute strains on freshwater globally, and population growth has driven modern farming practices towards the overuse of already scarce water resources. This coupled with the increased popularity of water-intensive green infrastructure has led to the focus of this project: integrating greywater recycling through vegetated walls to minimize freshwater use and promote sustainable wastewater management. By selecting wetland species accustomed to a saturated environment, we designed walls that were well suited to absorbing the varied contaminants of greywater, which was modeled after effluent from sources like laundry machines, showers, and dishwashers. We evaluated the treatment performance of the walls through the U.S. Environmental Protection Agency (EPA) and Maryland Department of the Environment (MDE) guidelines for pH, turbidity, total organic carbon (TOC/NPOC), total nitrogen (TN), chemical oxygen demand (COD), and plant health was monitored through qualitative metrics. The development of green walls with region-specific native plants may allow for greater accessibility in communities local to Maryland, and may be used in future applications of green infrastructure planning.

description: The high-energy emission ($400$ keV $- 2$ MeV) of Cygnus X-1 --the most well-studied Galactic black hole-- was recently found to be strongly polarized. The origin of this radiation is still unknown. In this work, we suggest that it is the result of non-thermal processes in the hot corona around the accreting compact object, and study the polarization of high-energy radiation expected for black hole binaries. Two contributions to the total magnetic field are taken into account in our study, a small scale random component related to the corona, and an ordered magnetic field associated with the accretion disk. The degree of polarization of gamma-ray emission for this particular geometry is estimated, as well as the angle of the polarization vector. We obtain that the corona+disk configuration studied in this work can account for the high degree of polarization of gamma-rays detected in galactic black holes without the need of a relativistic jet; specific predictions are made for sources in a low-hard state. In particular, the model is applied to the transient source \xtee; we show that if a new outburst of \xte is observed, then its gamma-ray polarization should be measurable by future instruments, such as ASTRO-H or the proposed ASTROGAM.

description: Disordered eating (DE) is a term that captures all maladaptive attitudes and behaviors around food consumption, often as a result of poor body image. The continuation of DE can progress into an eating disorder (ED), which results in inadequate nutrition. Individuals with ED are also at a higher deposition for developing psychiatric and medical comorbidities. Current research on DE and ED has historically centered on skinny, White, affluent girls (SWAG), inherently excluding marginalized identities from the majority of existing literature. Furthermore, there exists a severe gap in knowledge regarding ED and DE in boys and men. Factors that contribute to this gap include the underdiagnosis of ED, stigma towards masculine identities, barriers to care, and health literacy. The purpose of this study was to establish the relationship between the negative perceptions associated with DE and ED and its impact on the prevalence of DE symptoms and ability to engage in health-seeking behaviors among young men and those with marginalized identities. Data on DE, stigma, access to health care services, and general help-seeking was collected from a sample of college-aged undergraduate students at the University of Maryland, College Park (N = 257). Participants assigned male at birth (AMAB) were roughly twice as likely than participants assigned female at birth (AFAB) to be seen as weak for having a mental health problem (OR = 1.996, 95% CI = 1.10-3.62, p = .023). Findings indicate a cultural adherence to hegemonic ideals of masculinity which is a major aspect contributing to the stigma surrounding ED/DE in males. With the focus of this study being on a campus community, destigmatization efforts in male spaces and educational wellness resources that target at-risk individuals should be implemented. Future studies may examine the benefits and efficacy of such intervention and educational programs.

description: This paper presents and evaluates the performance of an optimal scheduling algorithm that selects the on/off combinations and timing of a finite set of dynamic electric loads on the basis of short term predictions of the power delivery from a photovoltaic source. In the algorithm for optimal scheduling, each load is modeled with a dynamic power profile that may be different for on and off switching. Optimal scheduling is achieved by the evaluation of a user-specified criterion function with possible power constraints. The scheduling algorithm exploits the use of a moving finite time horizon and the resulting finite number of scheduling combinations to achieve real-time computation of the optimal timing and switching of loads. The moving time horizon in the proposed optimal scheduling algorithm provides an opportunity to use short term (time moving) predictions of solar power based on advection of clouds detected in sky images. Advection, persistence, and perfect forecast scenarios are used as input to the load scheduling algorithm to elucidate the effect of forecast errors on mis-scheduling. The advection forecast creates less events where the load demand is greater than the available solar energy, as compared to persistence. Increasing the decision horizon leads to increasing error and decreased efficiency of the system, measured as the amount of power consumed by the aggregate loads normalized by total solar power. For a standalone system with a real forecast, energy reserves are necessary to provide the excess energy required by mis-scheduled loads. A method for battery sizing is proposed for future work.

description: Pancreatic cancer has a 12% five-year survival rate in the United States, making it the fourth deadliest cancer. Current treatment options include chemotherapy with and without radiation therapy, targeted therapy, or surgery; however, these options have limited success due to low efficiency and adverse effects. In this research, we investigate the efficiency of a proprietary technology NanoART631 (PCT/US2023/019974) invented by our advisor Dr. Tao Lowe and her collaborator Dr. Curt Civin in treating pancreatic cancer. NanoART631 is a nanogel system composed of thermoresponsive poly (N-isopropylacrylamide) and biodegradable dextran-lactate-2-hydroxyethyl-methacrylate, encapsulated with an artemisinin (ART) dimer with a molecular weight of 631 Da. NanoART631 previously demonstrated effective killing of human leukemia cells and sustained the release of ART631 for more than one month in the Lowe lab. However, NanoART631 has not been tested in regard to pancreatic cancer. In our study, we used Fourier transform infrared spectra (FTIR) to characterize the chemical structures of NanoART631s containing different amounts of ART631: 0, 2, 5 and 10 wt%. We also used Zetasizer Ultra to characterize the hydrodynamic particle size, polydispersity index (PDI) and zeta-potential of NanoART631s in water and two culture media for human pancreatic PANC-1 and MiaPaCa2 cells. The results showed that NanoART631s were monodisperse with hydrodynamic diameters between 100 and 230 nm and PDI <0.25 at 37 oC and both the cell culture media decreased the particle size and there was no difference of the effects of the two cell culture media on the particle size. The magnitudes of the zeta potential of 0, 2, 5 and 10 wt% NanoART631 in water at both room and body temperature were consistently below 20 mV. In both cell mediums at body temperature, the magnitudes of the zeta potential of 0, 2, 5 and 10 wt% NanoART631 were consistently below 5mV. We additionally used MTT assay to study the cytotoxicity of NanoART631s to PANC-1 and MiaPaCa2 cells as a function of concentration and determined the effectiveness of NanoART631s in killing the two cells by calculating their IC50s. The IC50s of NanoART631s containing 2, 5 and 10 wt% ART631 were between 20 and 200 nM depending on the cell type. The effectiveness of killing the both human pancreatic cancer cells increased with increasing the amount of ART631 in the nanoparticles. The NanoART631s have potential as an effective novel therapy to treat pancreatic as well as many other cancers.

description: As the first generation of large-scale solar installations begins to reach the end of their 25-year lifespan and solar power becomes more prevalent, solar waste is becoming an increasingly pressing global issue. Solar panels are difficult to disassemble and often end up in landfills, where they leach toxic metal compounds into the environment after disposal. Solar panel recycling can help ameliorate these environmental impacts, but existing recycling techniques often employ harmful chemicals or thermal treatments, which produce undesirable byproducts. This project aims to address environmental concerns associated with ethylene vinyl acetate (EVA) removal, one of the most challenging aspects of solar cell recycling. EVA is an adhesive polymer that joins the glass, silicon solar cell, and backsheet layers together. In this work, we investigate the effect that five chemical alternatives to toluene have on EVA. Gasification and pyrolysis are also explored as an alternative to chemical dissolution methods. Mass loss data and qualitative observations of post-treatment indicate that the chosen solvents can effectively aid in panel disassembly, with some demonstrating results similar to toluene. This project identifies multiple solvents that are promising candidates for the chemical treatment of solar cells for recycling purposes, whose environmental impacts are lower than those currently used in industry. However, the findings also underscore the difficulty of developing a solar panel recycling process free from harmful chemical waste and demonstrate the need to design panels with recycling in mind, especially through the use of alternative encapsulant and backsheet materials.

description: Programmable matter is well-researched from a theoretical perspective, but existing prototypes are yet to demonstrate all possible functionalities. This project aimed to create a functional system of self-assembling robots by integrating ideas from various projects. Areas of interest were the robot shape, electronics, actuation/latching method, wireless communication, and assembly algorithm. Electropermanent magnets were thought to be viable for latching with minimal power requirements, but material availability issues and insufficient magnetic force output were obstacles to successful actuation. Standard solenoids were considered as an alternative but also unsuccessful due to low magnetic force output. Currently, no alternative for actuation at this prototype’s scale has been found. An assembly algorithm was created that succeeds in small-scale situations required by the prototype, but would have issues being scaled; alternatives have been identified but not implemented. Overall, this prototype system was not functional but discovered important limitations on actuation previously considered theoretically viable.

description: The Human Immunodeficiency Virus is an autoimmune disease which targets the body’s immune system, leaving individuals at risk of worse infections, such as AIDS. Currently, HIV is treated via drug cocktails limited by synthesized particle size, architecture, material composition, and lack of controlled drug release. Advancements in additive manufacturing through the use of Direct Laser Writing (DLW) and biodegradable structures have allowed for new methods of drug cocktail delivery. This project utilizes additive manufacturing to develop a biodegradable capsule with geometry that can be easily modified to control the release of the HIV drug cocktails. A mixture of PEGDA 250 and PETA was optimal for fabricating microcapsules, a teardrop design was tested for shell performance, and microchips facilitate targeting liquid to the shell. Our research shows promise towards the delivery of medications via controlled release mechanisms by allowing for continuous administration of medication to maintain the therapeutic window.

description: Numerous methods have been developed for microplastics isolation and quantification in various environmental media, many of which require elaborate or expensive analytical equipment and decontaminated lab space. This study seeks to create a reproducible and economical method for isolating microplastics in surface water that rely on Nile Red staining. We use a Nile Red pre-staining step prior to sample digestion, density separation, and filtration to mitigate downstream in-lab contamination before quantification of microplastics via fluorescent microscopy. To test the method, we collected replicate surface water samples from several reaches of an urban stream in the Chesapeake Bay Watershed, USA seasonally for one year. The proposed sampling and quantification method found some success in these surface water samples with specific microplastics (≥20 μm) able to be enumerated.

description: An estimate of bee hive activity allows beekeepers and researchers to better understand trends in a colony’s health. This work presents a system utilizing an event-based vision sensor (e.g., Dynamic Vision Sensor, or DVS) to track flying bees in real-time with the intent of accurately monitoring the flow of bees in and out of an Apis mellifera colony. Neuromorphic event-based vision sensors like the DVS are well-suited to the detection of small, fast-moving bees with minimal latency due to the asynchronous pixels. Rather than processing and transferring full images, these pixels detect changes in brightness independently, only sending updates where movement occurs, dramatically reducing the computational load. Using this spatio-temporal input, event-based algorithms are able to track fast-moving bees in real-time to determine the position of the bee relative to the hive entrance, and by defining a boundary, count the number of bees leaving and returning. Due to the sensor’s temporal resolution, the flapping bee wing can be observed in flight and its wingbeat frequency can be estimated during tracking in real-time. To evaluate the proposed event-based tracking system, a side-by-side comparison with a frame-based camera at an active colony was performed. Real-time tracking of trends in bee activity should provide early warning signs of problems such as robbing, swarming, absconding, etc. Detailed analysis of wingbeat frequency may eventually provide a real-time detection system for invading insects.

description: Due to low survival rates and an unparalleled burden of non-small cell lung cancer on underserved communities, there is great urgency for innovative and accessible methods that will improve healthcare access for lung cancer patients. To combat this inequity, Team DOC aims to develop an AI model that is able to not only improve lung cancer diagnoses but also predict the progression of non-small cell lung cancer. We intend to evaluate the performance of a convolutional neural network on the LIDC-IDRI dataset and retrain the final layers of the model to improve its performance on the same dataset. Repeating this process on different model architectures allows us to determine which model performs optimally, providing a foundation to develop an end-to-end explainable AI workflow that can extract clinically relevant predictions of cancer progression for further analysis. Throughout our training process, we resolve to address the accuracy and potential for bias. Additionally, we are carrying out a survey among underserved populations and communities to discern the need for our improved cancer detection model. We hope that our model will be able to be implemented in communities with lack of access to healthcare systems to bridge the gap between underprivileged communities and unbiased care.

description: As widespread electric vehicle (EV) adoption faces hurdles due to limited charging accessibility, this research explores the potential of Vehicle-to-Vehicle (V2V) charging technology, particularly for residents in multi-unit dwellings. To assess the feasibility of this concept, we constructed a functional V2V charger prototype through multiple iterations. Using various Arduino projects focused on PWM and charging circuits, we achieved a successful V2V charger prototype, enabling data collection to inform future advancements in this promising technology.

description: In an effort to derive temperature based criteria of habitability for multicellular life, we investigated the thermal limits of terrestrial poikilotherms, i.e. organisms whose body temperature and the functioning of all vital processes is directly affected by the ambient temperature. Multicellular poikilotherms are the most common and evolutionarily ancient form of complex life on earth. The thermal limits for their active metabolism and reproduction are bracketed by the temperature interval 0C

description: We present our results on the Chandra X-ray Observatory Advanced CCD Imaging Spectrometer (ACIS) observations of the bright Oort Cloud comets C/2012 S1 (ISON) and C/2011 L4 (PanSTARRS). ISON was observed between 2013 October 31-November 06 during variable speed solar wind (SW), and PanSTARRS was observed between 2013 April 17-23 during fast SW. ISON produced an extended parabolic X-ray morphology consistent with a collisionally thick coma, while PanSTARRS demonstrated only a diffuse X-ray-emitting region. We consider these emissions to be from charge exchange (CX) and model each comet's emission spectrum from first principles accordingly. Our model agrees with the observational spectra and also generates composition ratios for heavy, highly charged SW ions interacting with the cometary atmosphere. We compare our derived SW ion compositions to observational data and find a strong agreement between them. These results further demonstrate the utility of CX emissions as a remote diagnostics tool of both astrophysical plasma interaction and SW composition. In addition, we observe potential soft X-ray emissions via ACIS around 0.2 keV from both comets that are correlated in intensity to the hard X-ray emissions between 0.4-1.0 keV. We fit our CX model to these emissions, but our lack of a unique solution at low energies makes it impossible to conclude if they are cometary CX in origin. We lastly discuss probable emission mechanism sources for the soft X-rays and explore new opportunities these findings present in understanding cometary emission processes via Chandra.

description: Context. Efforts to look for signatures of the first stars have concentrated on metal-poor halo objects. However, the low end of the bulge metallicity distribution has been shown to host some of the oldest objects in the Milky Way and hence this Galactic component potentially offers interesting targets to look at imprints of the first stellar generations. As a pilot project, we selected bulge field stars already identified in the ARGOS survey as having [Fe/H] ~ -1 and oversolar [alpha/Fe] ratios, and we used FLAMES-UVES to obtain detailed abundances of key elements that are believed to reveal imprints of the first stellar generations. Aims. The main purpose of this study is to analyse selected ARGOS stars using new high-resolution (R~45,000) and high-signal-to-noise (S/N >100) spectra. We aim to derive their stellar parameters and elemental ratios, in particular the abundances of C, N, the alpha-elements O, Mg, Si, Ca, and Ti, the odd-Z elements Na and Al, the neutron-capture s-process dominated elements Y, Zr, La, and Ba, and the r-element Eu. Methods. High-resolution spectra of five field giant stars were obtained at the 8m VLT UT2-Kueyen telescope with the UVES spectrograph in FLAMES-UVES configuration. Spectroscopic parameters were derived based on the excitation and ionization equilibrium of Fe I and Fe II. The abundance analysis was performed with a MARCS LTE spherical model atmosphere grid and the Turbospectrum spectrum synthesis code.

description: We present our model-independent and data-driven method to describe pseudoscalar meson transition form factors in the space- and (low-energy) time-like regions. The method is general and conforms a toolkit applicable to any other form factor, of one and two variables, with the potential to include both high- and low-energy QCD constraints altogether. The method makes use of analyticity and unitary properties of form factors, it is simple, systematic and can be improved upon by including new data. In the present discussion, the method is used to show the impact of experimental data for precision calculations in the low-energy sector of the Standard Model. In particular, due to its relevance for New Physics searches, we have considered the hadronic light-by-light scattering contribution to the anomalous magnetic moment of the muon (the pseudoscalar exchange contribution), the pseudoscalar decays into lepton pairs, and the determination of the mixing parameters of the $η$ and $η'$ system. For all of them we provide the most updated results in a data-driven manner.
