Berlin V2X: A Machine Learning Dataset from Multiple Vehicles and Radio Access Technologies (2022)

The evolution of wireless communications into 6G and beyond is expected to rely on new machine learning (ML)-based capabilities. These can enable proactive decisions and actions from wireless-network components to sustain quality-of-service (QoS) and user experience. Moreover, new use cases in the area of vehicular and industrial communications will emerge. Specifically in the area of vehicle communication, vehicle-to-everything (V2X) schemes will benefit strongly from such advances. With this in mind, we have conducted a detailed measurement campaign that paves the way to a plethora of diverse ML-based studies. The resulting datasets offer GPS-located wireless measurements across diverse urban environments for both cellular (with two different operators) and sidelink radio access technologies, thus enabling a variety of different studies towards V2X. The datasets are labeled and sampled with a high time resolution. Furthermore, we make the data publicly available with all the necessary information to support the onboarding of new researchers. We provide an initial analysis of the data showing some of the challenges that ML needs to overcome and the features that ML can leverage, as well as some hints at potential research studies.
Establishment of Best Practices for Evidence for Prediction (2019)

To ensure accurate estimates of predictive validity, the recommended best practices for predictive modeling include the following: (1) in-sample model fit indices should not be reported as evidence for predictive accuracy, (2) the cross-validation procedure should encompass all operations applied to the data, (3) prediction analyses should not be performed with samples smaller than several hundred observations, (4) multiple measures of prediction accuracy should be examined and reported, (5) the coefficient of determination should be computed using the sums of squares formulation and not the correlation coefficient, and (6) k-fold cross-validation rather than leave-one-out cross-validation should be used.
GaAsP Nanowires Grown by Aerotaxy (2016)

We have grown GaAsP nanowires with high optical and structural quality by Aerotaxy, a new continuous gas phase mass production process to grow III-V semiconductor based nanowires. By varying the PH3/AsH3 ratio and growth temperature, size selected GaAs1-xPx nanowires (80 nm diameter) with pure zinc-blende structure and with direct band gap energies ranging from 1.42 to 1.90 eV (at 300 K), (i.e., 0 ≤ x ≤ 0.43) were grown, which is the energy range needed for creating tandem III-V solar cells on silicon. The phosphorus content in the NWs is shown to be controlled by both growth temperature and input gas phase ratio. The distribution of P in the wires is uniform over the length of the wires and among the wires. This proves the feasibility of growing GaAsP nanowires by Aerotaxy and results indicate that it is a generic process that can be applied to the growth of other III-V semiconductor based ternary nanowires.
0790 Racial Differences in Self-Efficacy for Positive Airway Pressure Therapy Among Individuals Newly Diagnosed with Obstructive Sleep Apnea (2022)

Abstract Introduction Continuous positive airway pressure (CPAP) therapy is the first-line treatment for OSA, yet its effectiveness is limited by poor adherence. Self-efficacy is an individual’s belief that they can successfully execute a behavior to achieve a desired outcome. Evidence shows that self-efficacy predicts adherence to and outcomes of CPAP therapy, as do race and ethnicity. Little, however, is known about how self-efficacy may differ between racial and ethnic groups. Accordingly, we aimed to determine whether self-efficacy for CPAP differs by race and ethnicity among individuals newly diagnosed with OSA. Methods Adults newly diagnosed with OSA and prescribed CPAP who were enrolled in the NICEPAP Study (n=267, NCT05067088), a prospective, observational cohort study investigating predictors of CPAP adherence were assessed. Those with need for non-CPAP therapy or with unstable medical conditions (e.g., cancer receiving chemotherapy, severe lung, heart or mental health disorders) were excluded. Exposures were race and ethnicity. Outcomes were subscale scores of the Self-Efficacy Measure for Sleep Apnea (SEMSA) completed prior to CPAP initiation: perceived risk, outcome expectancy, and self-efficacy. SEMSA sub-scale scores for race/ethnicity were compared using Kruskal-Wallis test. Medians (Q1, Q3) are reported. Results We analyzed data for 52 participants (33 women) enrolled to date who identified as White (n=29), Black (n=14), More than one race (n=5) and Other (N=5). Participants were 51.0 (36.8, 58.8) years old with an apnea-hypopnea index of 17.0/hour (11.1, 26.0) and body-mass-index of 35.0 (31.6, 43.5) kg/m2. Baseline characteristics did not differ by race, except higher poverty (p=0.005) and less completed years of education (p=0.010) for Black participants. The SEMSA scores were not statistically different between each race. However, self-efficacy was significantly lower for Black participants vs. rest of the cohort combined (2.4 (1.9, 3.1) vs. 3.3 (2.7, 3.8) p=0.020). Poverty, but not education, may be a potential mediator of this relationship (mediation analysis p=0.052). There were no differences in SEMSA scores between Hispanic and Non-Hispanic participants. Conclusion In our cohort, self-efficacy for OSA therapy was lower for Black participants compared to those of other races. Targeting early interventions to improve CPAP self-efficacy in Black patients may improve OSA therapy outcomes. Support (If Any)
Impact of Quantized Side Information on Subchannel Scheduling for Cellular V2X (2018)

In Release 14, 3GPP completed a first version of cellular vehicle-to-everything (C-V2X) communications wherein two modalities were introduced. One of these schemes, known as \textit{mode-3}, requires support from eNodeBs in order to realize subchannel scheduling. This paper discusses a graph theoretical approach for semi- persistent scheduling (SPS) in \textit{mode-3} harnessing a sensing mechanism whereby vehicles can monitor signal-to-interference-plus-noise ratio (SINR) levels across sidelink subchannels. eNodeBs request such measurements from vehicles and utilize them to accomplish suitable subchannel assignments. However, since SINR values--herein also referred to as side information--span a wide range, quantization is required. We conclude that 3 bits per vehicle every 100 ms can provide sufficient granularity to maintain appropriate performance without severe degradation. Furthermore, the proposed algorithm is compared against pseudo-random and greedy SPS algorithms.
Performance Improvements in Small Earth Storable Rocket Engines- An Era of Approaching the Theoretical (2010)

The development of small earth storable liquid bipropellant rocket engines begin in earnest in the early 1960's for the Gemini and Apollo reaction control systems. These engines used nitrogen tetroxide oxidizer and aerozine-50 or monomethylhydrazine fuels. Specific impulse levels in the 280-290 lbf-sec/lbm range were demonstrated with burn times of up to a few hours. Over the last 50 years the performance of this engine group has improved, due in part to better material systems and thermal management approaches, to specific impulse levels approaching 335 seconds and operating times in excess of 40,000 seconds. In particular the Apollo reaction control thruster (model R-4D, 100 lbf) developed by The Marquardt Company in 1960 has evolved over the last era using new material systems, improved injector designs and optimized thermal management using liquid boundary layer cooling to a demonstrated specific impulse level in excess of 333 seconds. Combustion chamber wall temperatures approaching 4200°F have been demonstrated which result in large system operating margins. Additional engine development efforts have been successfully accomplished at the 200 lbf level with specific impulse levels approaching 327 seconds at considerably lower chamber operating temperatures.
Natural aging and Alzheimer’s disease pathology increase susceptibility to focused ultrasound-induced blood–brain barrier opening (2023)

Focused Ultrasound (FUS) paired with systemically-injected microbubbles (μB) is capable of transiently opening the blood-brain barrier (BBBO) for noninvasive and targeted drug delivery to the brain. FUS-BBBO is also capable of modulating the neuroimmune system, further qualifying its therapeutic potential for neurodegenerative diseases like Alzheimer's disease (AD). Natural aging and AD impose significant strain on the brain and particularly the BBB, modifying its structure and subsequently, its functionality. The emerging focus on treating neurodegenerative diseases with FUS-BBBO necessitates an investigation into the extent that age and AD affect the BBB's response to FUS. FUS-BBBO was performed with a 1.5-MHz, geometrically focused transducer operated at 450 kPa and paired with a bolus microbubble injection of 8 × 10<sup>8</sup> μB/mL. Here we quantify the BBBO, BBB closing (BBBC) timeline, and BBB permeability (BBBP) following FUS-BBBO in male mice with and without AD pathology, aged 10 weeks, one year, or two years. The data presented herein indicates that natural aging and AD pathology may increase initial BBBO volume by up to 34.4% and 40.7% respectively, extend BBBC timeline by up to 1.3 and 1.5 days respectively, and increase BBBP as measured by average K<sup>trans</sup> values up to 80% and 86.1% respectively in male mice. This characterization of the BBB response to FUS-BBBO with age and AD further clarifies the nature and extent of the functional impact of these factors and may offer new considerations for planning FUS-BBBO interventions in aged and AD populations.
Abstract P3-01-16: Utilizing a decellularized patient-derived xenograft tumor model for the evaluation of triple negative breast cancer (2020)

Abstract Triple negative breast cancer (TNBC) is an aggressive and heterogeneous disease with poorer prognoses compared to other breast cancer (BC) subtypes. This is due, in part, to the lack of clinically approved targeted therapeutics. The mechanisms underlying the process of recurrence in TNBC remain elusive. Traditional 2D BC models do not accurately mimic the cell-matrix interactions and extracellular matrix (ECM) composition that are vital to maintaining the tumor microenvironment and are unique to individual patient tumors. Here we introduce and utilize our novel decellularized patient-derived xenograft (PDX) TNBC model, TU-BcX-4IC (“4IC”), to address this knowledge discrepancy. In this study, we seeded TU-BcX-4IC PDX-derived cells onto TU-BcX-4IC PDX decellularized tumor scaffold (“4IC + 4IC scaffold”) and implanted our model into SCID/beige mice. Concordantly, mice were inoculated with TU-BcX-4IC cells mixed with Matrigel and PBS (“4IC + Matrigel”), or PBS alone (“4IC + PBS”). We demonstrate that our decellularized model, along with the injected cells, can form tumors in vivo. We also show that the “4IC + 4IC scaffold” model retains aberrant mitotic figures seen in the original 4IC PDX. However, due to inconsistent tumor growth in the experimental group, optimization of cell seeding onto our decellularized scaffold model is needed to produce consistent tumor propagation in vivo. We compared the number and area of metastases in the lungs and livers excised from the mice. The area and number of lung metastases were lower in mice implanted with “4IC + 4IC scaffold,” albeit not significantly. There was little difference in the area of liver metastases in all groups. The number of liver metastases was lower in the “4IC + Matrigel” and “4IC + 4IC scaffold” groups; however, there was no significance. All groups had a greater propensity to metastasize to the livers. We also compared differences in human and mouse ECM gene expression amongst all groups. Our decellularized scaffold model can be used as a platform to evaluate ECM onco-architecture and composition. The data presented here will help enhance our understanding of the breast tumor microenvironment and elucidate the mechanisms underlying tumorigenesis and recurrence in TNBC.

Pacing in Distal Left Ventricular Hypertrophic Cardiomyopathy (1998)

We report the case of an 85-year-old woman with distal LV hypertrophy resulting in an intraventricular pressure gradient and incomplete systolic emptying who benefited from permanent DDD pacing. Our experience based on this case suggests that permanent dual chamber pacing might be a safe and effective therapy also in symptomatic patients with the rare form of hypertrophic cardiomyopathy with left mid-ventricular obstruction resulting in incomplete emptying of the apical portion of the LV and a significant intraventricular pressure gradient that was not responding to pharmacological therapy.
Face recognition under varying pose (1994)

Researchers in computer vision and pattern recognition have worked on automatic techniques for recognizing human faces for the last 20 years. While some systems, especially template-based ones, have been quite successful on expressionless, frontal views of faces with controlled lighting, not much work has taken face recognizers beyond these narrow imaging conditions. Our goal is to build a face recognizer that works under varying pose, the difficult part of which is to handle face relations in depth. Building on successful template-based systems, our basic approach is to represent faces with templates from multiple model views that cover different poses from the viewing sphere. To recognize a novel view, the recognizer locates the eyes and nose features, uses these locations to geometrically register the input with model views, and then uses correlation on model templates to find the best match in the data base of people. Our system has achieved a recognition rate of 98% on a data base of 62 people containing 10 testing and 15 modeling views per person.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Effect of outer membrane of Treponema denticola on bone resorption (1993)

The effect of the outer membrane (outer sheath) of Treponema denticola on bone resorption was studied. Bone resorption was measured by the release of previously incorporated 45Ca from the shafts of the radii and ulnae of 19-day fetal rats. A treated-over-control ratio (T/C ratio) significantly greater than 1 indicated the stimulation of bone resorption by the test substance. The addition of outer membrane of T. denticola increased the release of 45Ca from the assay bones. The minimum concentrations required to yield significant 45Ca release from the assay bones were 15, 22 and 75 micrograms protein/ml for serovars a, b and c, respectively. These protein values corresponded to estimated lipopolysaccharide contents of 0.6, 0.8 and 2.8 micrograms/ml, based on 3-deoxy-2-manno-octulosonate analysis. Heat treatment of outer membrane (60 degrees for 30 min) did not change the effect on 45Ca release. Parathyroid hormone or prostaglandin E2, known to act synergistically with lipopolysaccharides in bone resorption, was also added to the assay system. Neither prostaglandin E2 at 10(-7) M nor parathyroid hormone at 40 ng/ml, by itself, increased 45Ca release. However, in the presence of 10 micrograms protein/ml of outer membrane of serovar b at 120 h, the T/C ratio was increased to 1.31 +/- 0.07 and 1.58 +/- 0.118, respectively. These results suggest that a lipopolysaccharide-like material is present in the outer membrane of T. denticola that may be responsible for bone resorption in the in vitro system.
First in human study with a prodrug of galantamine: Improved benefit‐risk ratio? (2016)

Gln-1062 was better tolerated than galantamine in doses with the same molarity and led to improved effects in cognitive tests. This is most likely caused by the more favorable distribution ratio between peripheral and central cholinesterase inhibition. These results give reason for further exploration of this compound.
Vibronic Structure in Room Temperature Photoluminescence of the Halide Perovskite Cs3Bi2Br9 (2016)

We report a study on the optical properties of the layered polymorph of vacancy-ordered triple perovskite Cs<sub>3</sub>Bi<sub>2</sub>Br<sub>9</sub>. The electronic structure, determined from density functional theory calculations, shows the top of the valence band and bottom of the conduction band minima are, unusually, dominated by Bi s and p states, respectively. This produces a sharp exciton peak in the absorption spectra with a binding energy that was approximated to be 940 meV, which is substantially stronger than values found in other halide perovskites and, instead, more closely reflects values seen in alkali halide crystals. This large binding energy is indicative of a strongly localized character and results in a highly structured emission at room temperature as the exciton couples to vibrations in the lattice.
The SUN workstation architecture (1982)

The Sun workstation is a personal computer system that combines graphics and networking capabilities with powerful local processing. The workstation has been developed for research in VLSI design automation, text processing, distributed operating systems and programming environments. Clusters of Sun workstations are connected via a local network sharing a network-based file system. The Sun workstation is based on a Motorola 6800 processor, has a 1024 by 800 pixel bitmap display, and uses Ethernet as its local network. The hardware supports virtual memory management, a RasterOP mechanism for high-speed display updates, and data-link-control for the Ethernet. The entire workstation electronics consists of 260 chips mounted on three 6.75 by 12 inch PC boards compatible with the IEEE 796 Bus (Intel Multibus). In addition to implementing a workstation, the boards have been configured to serve as network nodes for file servers, printer servers, network gateways, and terminal concentrators. The report discusses the architecture and implementation of the Sun workstation, gives the background and goals of the project, contemplates future developments, and describes in detail its three main components: the processor, graphics, and Ethernet boards.
Wide-baseline 3D reconstruction from digital stills (2003)

The last decade saw tremendous progress in the area of structure-and-motion. Techniques have been developed to compute the camera trajectory and reconstruct scenes in 3D based on nothing but a video or a set of closely spaced images. No extra information or calibration is needed to perform the reconstruction. This paper presents extensions on the traditional shape-from-video pipeline in order to deal with wide-baseline conditions, i.e. views that are much farther apart. The algorithms for both the sparse and dense correspondence search need to be upgraded for the system to deal with these wide-baseline views. These new techniques are discussed in this paper and results are shown.
Strong metal–support interactions of Co-based catalysts facilitated by dopamine for highly efficient ammonia synthesis: in situ XPS and XAFS spectroscopy coupled with TPD studies (2018)

We report a new strategy for strengthening metal-support interaction and stabilizing Co nanoparticles at high temperature. Through the use of dopamine and removal of carbon layers by thermal N2 treatment, ceria-based Co catalysts that are efficient and highly stable for ammonia synthesis can be obtained. The ammonia synthesis rate at 425 °C and 1 MPa is enhanced from 3.81 mmolNH3 gcat-1 h-1 over Co/CeO2 to 19.12 mmolNH3 gcat-1 h-1 over a dopamine-mediated catalyst. The superior catalytic performances of the dopamine-mediated Co/CeO2 catalyst are associated with smaller crystalline size, stronger metal-support interaction and lower N2 activation energy.
Evaluation of Fire Blight Resistance of Malus sieversii Populations from Central Asia (1997)

Malus sieversii is one of the primary progenitors of the cultivated apple. Since 1989, several collecting trips have been made to central Asia by personnel of the USDA and Cornell Univ. to collect seeds of wild Malus sieversii from many diverse ecosystems. In 1992, an ex situ plot in Geneva, N.Y., was established with trees grown from seed that was collected in three different habitats in Kazakstan, Tajikistan, and Uzbekistan in 1989. In 1995, trees grown from seed that was collected in five additional habitats in Kazakstan and Kyrgyzstan in 1993 were added to the ex situ plot. In the summers of 1995 and 1996, tips of vigorously growing shoots of 1135 seedlings from 79 different populations were inoculated by hypodermic syringe with 5 × 10 8 cfu/ml of Erwinia amylovora strain Ea273. Seedlings from the 1989 collection were in the fourth and fifth field-growing seasons, with some beginning to bear fruit. Seedlings from the 1993 collection were in first and second field-growing seasons. Results from both seasons indicated that individuals within each of the 79 populations of M. sieversii are resistant to fire blight (defined as ≤20% shoot length infected). Resistance differed among populations, with some populations having no resistant individuals and others having &gt;80% of the seedlings resistant. The range of resistance is quite similar to that seen among apple cultivars from North America and Europe. In another test, some accessions from 1989 collection had sufficient bloom for inoculation in 1995 and 1996. At full bloom, blossoms on these trees were inoculated with the E. amylovora suspensions (5 × 10 7 cfu/ml) using a backpack sprayer. These also gave diverse resistant reactions.
Stereoselective Synthesis of 3‐Alkylideneoxindoles using Tandem Indium‐Mediated Carbometallation and Palladium‐Catalyzed Cross‐Coupling Reactions (2005)

Abstract The first efficient methods for the stereoselective synthesis of various ( E )‐, ( Z )‐, and disubstituted 3‐alkylideneoxindoles via radical cyclization reactions were investigated using tandem indium‐mediated carbometallation and palladium‐catalyzed cross‐coupling reactions. The proper combination of substrates and reaction conditions is important for good yields. The key step is the first stereoselective carboindation reaction using the strong coordination ability of an indium cation to the amide carbonyl oxygen. We applied this method to the synthesis of TMC‐95A precursor. A new N ‐debenzylation method with N ‐hydroxyphthalimide‐O 2 ‐Co(OAc) 2 ‐Mn(OAc) 2 was also developed using a one‐electron oxidation procedure.
