FedTour: Participatory Federated Learning of Tourism Object Recognition Models with Minimal Parameter Exchanges between User Devices (2022)

In this paper, we propose FedTour, a federated learning-based method for training tourism object recognition models, which utilizes short-distance direct communication between user devices and maximizes the model performance within a limited number of updates. In FedTour, whenever two user devices are within range, they first exchange metadata including the learning degree (e.g., recognition accuracy) of their models, and determine whether it is effective to integrate the peer model by using a regressor trained with various pairs of models with different accuracy to predict the accuracy of the merged model. Once it is deemed effective, the model parameters are exchanged and the model is updated using FedAvg (averaging weights of two models of user devices). By carefully setting the threshold of whether FedAvg is applied or not, model performance is improved within a limited number of model parameter exchanges resulting in lower power consumption of user devices. We conducted a simulation using mobile phone trace data of actual users in a real sightseeing area and evaluated the improvement in accuracy of a CNN model that recognizes 10 objects while limiting the number of model parameter exchanges to only 40. Results show FedTour increased the initial model accuracy by 112%, while the baseline gossip-based method achieved 69%.
An End-to-End Model for Question Answering over Knowledge Base with Cross-Attention Combining Global Knowledge (2017)

With the rapid growth of knowledge bases (KBs) on the web, how to take full advantage of them becomes increasingly important. Question answering over knowledge base (KB-QA) is one of the promising approaches to access the substantial knowledge. Meanwhile, as the neural networkbased (NN-based) methods develop, NNbased KB-QA has already achieved impressive results. However, previous work did not put more emphasis on question representation, and the question is converted into a fixed vector regardless of its candidate answers. This simple representation strategy is not easy to express the proper information in the question. Hence, we present an end-to-end neural network model to represent the questions and their corresponding scores dynamically according to the various candidate answer aspects via cross-attention mechanism. In addition, we leverage the global knowledge inside the underlying KB, aiming at integrating the rich KB information into the representation of the answers. As a result, it could alleviates the out-of-vocabulary (OOV) problem, which helps the crossattention model to represent the question more precisely. The experimental results on WebQuestions demonstrate the effectiveness of the proposed approach.

Time-Aware Location Prediction by Convolutional Area-of-Interest Modeling and Memory-Augmented Attentive LSTM (2020)

Personalized location prediction is key to many mobile applications and services. In this paper, motivated by both statistical and visualized preliminary analysis on three real datasets, we observe a strong spatiotemporal correlation for user trajectories among the visited area-of-interests (AoIs) and different time periods on both weekly and daily basis, which directly motivates our time-aware location prediction model design called &#x201C;<inline-formula><tex-math notation="LaTeX">$t$</tex-math><alternatives><mml:math><mml:mi>t</mml:mi></mml:math><inline-graphic xlink:href="liu-ieq1-3005735.gif"/></alternatives></inline-formula>-LocPred&#x201D;. It models the spatial correlations among AoIs by coarse-grained convolutional processing of the user trajectories in AoIs of different time periods (&#x201C;ConvAoI&#x201D;); and predicts his/her fine-grained next visited PoI using a novel memory-augmented attentive LSTM model (&#x201C;mem-attLSTM&#x201D;) to capture long-term behavior patterns.

Effect of lipid vesicle (liposome) encapsulation of methotrexate on its chemotherapeutic efficacy in solid rodent tumors. (1978)

Abstract The possibility of the use of unilamellar phospholipid vesicles (liposomes) as carriers of methotrexate (MTX) was explored to overcome the resistance of solid tumors to the drug. Unilamellar vesicles were prepared by sonic dispersion of phosphatidylcholine:cholesterol:stearylamine (4:3:1) in an aqueous solution containing MTX. In MTX-resistant, cortisol-sensitive P1798 mouse lymphosarcoma cells in suspension, the uptake of [ 3 H]MTX at a concentration of 10 -6 m was 54% greater when the drug was encapsulated in lipid vesicles than that observed with the free drug. Daily i.p. injections of vesicle-entrapped MTX (1.0 mg/kg) into mice bearing established P1798 tumors for 4 consecutive days, a regimen that was ineffective with free MTX, resulted in an 80% reduction in tumor mass; this effect was greater than that achieved by 5 times the dosage of free drug. MTX-sensitive Murphy-Sturm rat lymphosarcoma cells in suspension showed a 2.6-fold increase in MTX uptake when the drug was encapsulated in lipid vesicles as compared to the free MTX at a concentration of 10 -6 m. Treatment of rats bearing the rat Murphy-Sturm lymphosarcoma tumor with MTX (0.5 mg/kg), following the regimen used previously, caused a 82% reduction in tumor mass when MTX was encapsulated in lipid vesicles compared to a 52% reduction in tumor mass achieved by administration of free drug. These results indicate that encapsulation of MTX in lipid vesicles enhances its association with tumor cells in vitro and improves the response of solid rodent tumors to treatment with MTX.
Elevated ammonia release from dystrophic chicken muscle cell and fibroblast cultures (1984)

The activity of adenosine monophosphate (AMP)-aminohydrolase, the major NH3-producing enzyme in skeletal muscle, was approximately 35% lower in 7-day dystrophic muscle cell cultures than in normal muscle cell cultures. However, the release rate of NH3 from dystrophic muscle cells was 45% higher than that from normal muscle cells. The reasons for this apparent discrepancy are not clear. To determine indirectly if deamination of amino acids from protein degradation contributed to NH3 release, cells were incubated with 100 micrograms/ml of the protease inhibitor, leupeptin. Leupeptin reduced the rate of NH3 release by only 18.8% in normal muscle cells and 16% in dystrophic muscle cells. The release of NH3 was also higher from dystrophic chicken fibroblast cultures.
Efficient color code decoders in $d\geq 2$ dimensions from toric code decoders (2019)

We introduce an efficient decoder of the color code in $d\geq 2$ dimensions, the Restriction Decoder, which uses any $d$-dimensional toric code decoder combined with a local lifting procedure to find a recovery operation. We prove that the Restriction Decoder successfully corrects errors in the color code if and only if the corresponding toric code decoding succeeds. We also numerically estimate the Restriction Decoder threshold for the color code in two and three dimensions against the bit-flip and phase-flip noise with perfect syndrome extraction. We report that the 2D color code threshold $p_{\textrm{2D}} \approx 10.2\%$ on the square-octagon lattice is on a par with the toric code threshold on the square lattice.

Limited inner ear morphogenesis and neurosensory development are possible in the absence of GATA3 (2011)

Haploinsufficiency of Gata3 causes hypoparathyroidism, deafness and renal dysplasia (HDR) syndrome in mice and humans. Gata3 null mutation leads to early lethality around embryonic day (E)11.5, but catecholamine precursor administration can rescue Gata3 null mutants to E16.5. At E11.5, GATA3 deficiency results in the development of an empty otocyst with an endolymphatic duct. However, using rescued mice we found that some morphogenesis and neurosensory development is possible in the ear without Gata3. Extending previous studies, we find that at E16.5, Gata3 mutant inner ears can undergo partial morphogenesis and develop an endolymphatic duct, a utricular and saccular recess, and a shortened cochlear duct. In addition to the obvious morphogenic aberrations, these studies demonstrate that a subset of neurons develop and connect a fragmented sensory patch of MYO7A-positive hair cells to the vestibular nuclei of the brainstem. In situ hybridization studies reveal altered expression of several transcription factors relevant to ear development and we hypothesize that this may relate to the observed dysmorphia and restricted neurosensory development. While a cochlear duct can form, there is no concurrent cochlear neurosensory development, observations consistent with specific hearing defects encountered by HDR patients and mice with Gata3-associated expression alterations. Gata3 null mutant phenocopies the otic maldevelopment (cochlear duct formation in the absence of neurosensory development) seen in Foxg1cre mediated conditional deletion of microRNA processing enzyme, Dicer1. Finally, while GATA3 is expressed in the developing vestibulo-cochlear efferent (VCE) neurons, and its absence in the null mutants disrupts VCE projections to the ear, loss of GATA3 does not affect VCE progenitor cell migration.
The Quantity and Distribution of Radiolabeled Dexamethasone Delivered to Tissue by Iontophoresis (1980)

A pilot study was conducted in the first of two monkeys using either radiolabeled Dm-Na-P or radiolabeled hydrocortisone sodium succinate, together with lidocaine HCl. This study indicated an approximately tenfold increase in the quantity of Dm-Na-P delivered to the test electrodes (4 mA; 20 minutes) whereas the quantity of hydrocortisone delivered from the test electrodes was only marginally (approximately 10%) increased as compared with that from the controls. In terms of an anti-inflammatory activity, the effective dose of Dm-Na-P in all tissue layers underlying the test electrodes was at least tenfold that of the hydrocortisone. Therefore, further trials with hydrocortisone were abandoned. In the second animal, positive test electrodes (5 mA; 20 minutes, were sited over five joints on the right side of the body and matching control electrodes (0 mA; 20 minutes) were placed over corresponding joints on the left side of the body. The control and test electrodes each contained 1.0 ml tritium-labeled Dm-Na-P (approximately 4.0 mg) and 2.0 ml 4% lidocaine HCl (80 mg). Local tissue concentrations of Dm-Na-P were higher than those that would be obtained by systematic therapy and lower than would be obtained by local injection.
Theory of thermal and kinetic extinction of diffusion flames (1987)

The structure of a diffusion flame with a three-step chain mechanism, consisting of two high-activation-energy thermoneutral branching reactions and zero-activation-energy exothermic termination reaction, has been studied using activation energy asymptotics via the model problems of counterflow and droplet flames. The analysis identifies three types of flames, depending on whether the rate of the termination reaction is fast, moderate, or slow. For the fast recombination regime a unique extinction criterion has been derived which contains a chemical extinction limit and a thermal extinction limit; the latter case is identified as Linan's extinction criterion. For the moderate and slow recombination regimes distinct extinction states do not exist.
Synthesis and Antimicrobial Evaluation of Novel Bis-&#946;-lactam Grafted Macrocycles (2014)

A series of macrocyclic bis-β-lactams has been synthesized in three good yielding steps using a Staudinger [2+2] cycloaddition reaction of ketene derived from phenoxyacetyl chloride as the key step. The reaction provided a diastereomeric mixture of cis-anti-cis (C2-symmetry) and cis-syn-cis (meso) bis-β-lactam grafted macrocycles which were screened for their in vitro antibacterial and antifungal activities against four human pathogenic bacteria and two pathogenic fungi. Compounds 6a and 6b exhibited antibacterial activity at lower concentration against four bacterial pathogens and compounds 10b and 12a showed antifungal activity against two fungal pathogens when compared to reference control. Keywords: Bis-β-lactam, diimines, staudinger reaction, macrocycles, antimicrobial activity.
Gait and Functional Outcomes Between Cruciate-Retaining and Cruciate-Substituting Implants in Total Knee Arthroplasty: A Prospective, Randomized Study. (2019)

Significant debate persists about posterior cruciate-retaining (CR) versus posterior cruciate-substituting (PS) implant design for total knee arthroplasty (TKA). This study sought to test the hypothesis that CR TKA will facilitate improved early functional outcomes in gait compared with PS TKA. Patients were randomized to either the CR or PS implant. Various patient-reported and surgeon-reported outcomes as well as gait analyses were obtained pre- and postoperatively. Patients undergoing PS TKA had higher University of California, Los Angeles activity scores at 12 months. No significant difference in spatiotemporal, kinematic, or kinetic parameters between groups was detected, but there was a trend toward quadriceps overuse gait pattern in the CR group. Patients undergoing TKA with a PS implant were more willing to engage in regular higher level physical activity. The CR implant may be a risk factor for quadriceps overuse gait pattern, while the PS implant may be protective against quadriceps overuse.

Routine electronic monitoring of fetal heart rate and uterine activity during labor. (1975)

Routine electronic monitoring has been performed on 2411 labor patients at Booth Memorial Medical Center. Most recently, 88% of all patients delivered were monitored. As a direct result of this program, intrapartum stillbirths have been dramatically reduced from 1.2/1000 livebirths to 0.5/1000 livebirths. Perinatal mortality for fetuses over 1000 g has fallen to 8.8/1000 deliveries. Apgar scores below 6 at 5 minutes have decreased from a rate of 24/1000 to 14/1000 livebirths. No increase in cesarean sections for fetal distress has occurred although the primary cesarean section rate has increased over the past 10 years, apparently unrelated to fetal monitoring. It is strongly recommended that all patients in labor be monitored by currently available technics.
Complex Dynamical Behavior in the Shear‐Displacement Model for Bulk Metallic Glasses during Plastic Deformation (2018)

In this paper, a fresh shear‐displacement model is developed for the plastic deformation of the bulk metallic glasses. The multiscale behavior in the shear banding process and the dynamics transition with the parameters are investigated in analytical form. We present a theoretical support for the transition from unstable states to stable states in the experiment by multiscale analysis and the stability analysis. With the small parameter increasing from negative to positive, the stability of the shear slipping displacement system changes, and there is a limit cycle at the transition stage. Meanwhile, the phase diagram and the power spectrum also suggest that there is dynamics transition with the parameter changing. Moreover, the complexity is analyzed for different disturbance parameters, and it is coincident with the fact that the solution is more irregular for larger disturbance. In addition, we find that the amplitude of solution decreases with the temperature decreasing, which is consistent with the experimental results that the amplitude of the serration is smaller and smaller as the temperature decreases.
Autism Spectrum Disorders (2005)

Autism is a developmental disorder, characterized by repetitive behaviors and by deficits in social skills and communicative abilities. Autism spectrum disorders affect 60 out of 10,000 individuals, resulting in significant costs to families and society. Neuropathological and imaging studies point to abnormalities in the limbic system and the cerebellum, and accelerated brain grown in the first 2 years of life. Abnormalities in serotonin function have been identified in affected patients and their families. Genetic studies document high concordance in monozygotic twins and genome screens have identified multiple loci as possibly associated with autism, with the strongest evidence pointing to regions 2q and 7q. Although there is a relative lack of well-controlled treatment studies, selective serotonin reuptake inhibitors and atypical antipsychotics are useful in the treatment of repetitive behaviors and aggression. Nonpharamacological interventions include intensive early childhood educational programs, and interventions targeted at problem behaviors and social skills improvement.
Design and evaluation of a vertically integrated passive two‐dimensional beam switching antenna array at 60 GHz (2019)

A millimeter-wave two-dimensional (2D) beam switching planar microstrip patch antenna array excited by a 4 × 4 substrate-integrated waveguide Butler matrix (BM) is presented in this article. The BM architecture is modified to feed the planar array in a vertically integrated multilayer design to minimize parasitic effects due to junction discontinuity and reduce the radio frequency (RF) front-end footprint. This feed architecture enables the designer to control the phased array inputs to achieve a set of beam directions in four quadrants of radiation space at a desired elevation angle. For verification of beam switching via over-the-air measurements at 60 GHz, a bench-top anechoic chamber with proper transmitter and receiver antenna positioners was designed and fabricated using in-house laboratory resources. 2D beam steering was confirmed in the intended four quadrants of radiation space at ϕ0 = 50°, 140°, 220°, and 300° and θ0 = 30° ± 5°, meeting the design specifications with a very good margin. Each switched beam demonstrated between 5 and 6 dBi gain at 60 GHz, which is within 1 dB deviation from the simulated results.
Conformation of Glycomimetics in the Free and Protein-Bound State:  Structural and Binding Features of theC-glycosyl Analogue of the Core Trisaccharide α-d-Man-(1 → 3)-[α-d-Man-(1 → 6)]-d-Man (2002)

The conformational properties of the C-glycosyl analogue of the core trisaccharide alpha-D-Man-(1 --> 3)-[alpha-D-Man-(1 --> 6)]-D-Man in solution have been carefully analyzed by a combination of NMR spectroscopy and time-averaged restrained molecular dynamics. It has been found that both the alpha-1,3- and the alpha-1,6-glycosidic linkages show a major conformational averaging. Unusual Phi ca. 60 degrees orientations for both Phi torsion angles are found. Moreover, a major conformational distinction between the natural compound and the glycomimetic affects to the behavior of the omega(16) torsion angle around the alpha-1 --> 6-linkage. Despite this increased flexibility, the C-glycosyl analogue is recognized by three mannose binding lectins, as shown by NMR (line broadening, TR-NOE, and STD) and surface plasmon resonance (SPR) methods. Moreover, a process of conformational selection takes place, so that these lectins probably bind the glycomimetic similarly to the way they recognize the natural analogue. Depending upon the architecture and extension of the binding site of the lectin, loss or gain of binding affinity with respect to the natural analogue is found.
Chemical cleaning of coal by molten caustic leaching after pretreatment by low-temperature devolatilization (2023)

Pretreatment of coal by devolatization at temperatures ranging from about 420.degree. C. to about 450.degree. C. for from about 10 minutes to about 30 minutes before leaching with molten caustic leads to a significant reduction in carbonate formation, greatly reducing the cost of cleaning coal on a per ton basis.
