description: This Traffic Tech Technology Transfer Series report briefly summarizes a larger report, Exploring the Predictive Validity of Drug Evaluation and Classification Programs, Report No. DOT 812 959, that studied which combinations of drug-related signs and symptoms from the Drug Evaluation and Classification (DEC) protocol most efficiently and effectively predicted the drug category or combination used by the subjects. A sample of 2,261 DEC evaluations conducted on suspected drug-impaired drivers in 11 States included cases that involved specific drug categories and two-drug combinations commonly encountered by drug recognition experts. Thirteen drug-related indicators were found to significantly contribute to the prediction of drug category; 12 indicators contributed significantly to the prediction of drug combinations.

description: We consider various configurations of T-branes which are non-abelian bound states of branes and were recently introduced by Cecotti, Cordova, Heckman and Vafa. They are a refinement of the concept of monodromic branes featured in phenomenological F-theory models. We are particularly interested in the T-branes corresponding to Z3 and Z4 monodromies, which are used to break E7 or E8 gauge groups to SU(5) GUT. Our results imply that the up-type and down-type Yukawa couplings for the breaking of E7 are zero, whereas up-type and down-type Yukawa couplings, together with right handed neutrino Yukawas are non-zero for the case of the breaking of E8. The dimension four proton decay mediating term is avoided in models with either E7 or E8 breaking.

description: Channel modeling is a fundamental task for the design and evaluation of wireless technologies and networks, before actual prototyping, commercial product development and real deployments. The recent trends of current and future mobile networks, which include large antenna systems, massive deployments, and high-frequency bands, require complex channel models for the accurate simulation of massive MIMO in mmWave and THz bands. To address the complexity/accuracy trade-off, a spatial channel model has been defined by 3GPP (TR 38.901), which has been shown to be the main bottleneck of current system-level simulations in ns-3. In this paper, we focus on improving the channel modeling efficiency for large-scale MIMO system-level simulations. Extensions are developed in two directions. First, we improve the efficiency of the current 3GPP TR 38.901 implementation code in ns-3, by allowing the use of the Eigen library for more efficient matrix algebra operations, among other optimizations and a more modular code structure. Second, we propose a new performance-oriented MIMO channel model for reduced complexity, as an alternative model suitable for mmWave}/THz bands, and calibrate it against the 3GPP TR 38.901 model. Simulation results demonstrate the proper calibration of the newly introduced model for various scenarios and channel conditions, and exhibit an effective reduction of the simulation time (up to 16 times compared to the previous baseline) thanks to the various proposed improvements.
Optimization of lipid nanoparticles containing small molecule drugs and genetic drugs
Creators: name: Chander, Nisha
Publisher: name: University of British Columbia
Year: 2023

description: Lipid-based nanoparticle (LNP) drug delivery vehicles can be used for in vivo delivery of a variety of bioactive molecules including nucleic acid polymers and small molecule drugs for applications ranging from improving the efficacy of anticancer drugs to enabling gene therapies. While liposomal systems containing small molecule drugs can be designed to be relatively nontoxic and long circulating, the ability to trigger rapid release of drug cargo at the target site remains elusive, severely limiting their therapeutic index. The first objective of this thesis is to develop lipid nanoparticles that can release a larger payload at the target site to improve their overall efficacy. Despite more than 30 years of experimentation, triggered release systems for liposomes containing anticancer drugs that leak contents in response to local heating or irradiation have failed to result in clinically approved applications. Chapters 3 and 4 of this thesis focus on incorporating photoswitchable lipids or metal nanoparticles into previously well-established liposomes, making them responsive to externally applied radiation such as laser light to trigger drug release. These novel liposomal systems have similar size and drug encapsulation properties as parent systems, while also exhibiting triggered release properties. Additionally, systems currently being used for delivery of genetic drugs such as RNAbased drugs only result in effective gene silencing or gene expression in the liver. The second objective of this thesis is to develop transfection competent long circulating systems that can transfect extra-hepatic tissues following intravenous administration. Chapter 5 of this dissertation describes an attempt to increase the proportion of so-called “helper” lipids in LNP formulations containing mRNA. It is shown that high (40 mol%) levels of helper lipids such as egg sphingomyelin (ESM) can result in improved gene expression both in vitro and in vivo, particularly in extrahepatic tissues such as bone marrow. This ability is attributed to the unique morphology of these LNP systems which exhibit a “solid” hydrophobic core surrounded by a lipid bilayer. Such systems allow improved distribution to extrahepatic tissues due to an enhanced circulation lifetime.

description: All-Optical Network (AON) is a network where the user-network interface is optical and the data does undergo optical to electrical conversion within the network. AONs are attractive because they promise very high rates, flexible switching and broad application support. There are two technologies for AON: Wavelength Division Multiplexed (WDM) and Optical Time Division Multiplexed (OTDM). OTDM transmission systems are becoming increasingly important as one of the key technologies satisfying the growing demand for large capacity optical networks. Although OTDM has several advantages in terms of operation system, such as natural accommodation of higher bit rate payloads, it introduces many security vulnerabilities, which do not exist in traditional networks. One of the serious problems with OTDM is the fact that optical crosstalk is additive, and thus the aggregate effect of crosstalk over a whole all-optical network (AON) may be more nefarious than a single point of crosstalk. This is because crosstalk can spread rapidly through the network, causing additional awkward failures and triggering multiple undesirable alarms. This results in the continuous monitoring and identification of the impairments becoming challenging in the event of transmission failures. In this paper we propose a novel approach for detecting and localizing crosstalk in OTDM transmission systems that can participate in some tasks for fault management in optical network.

The study of novel reactivities of phosphaalkenes towards N-heterocyclic carbenes and related systems
Creators: name: Han, Zeyu
Publisher: name: University of British Columbia
Year: 2022

description: This thesis outlines the results from the projects undertaken as a part of my PhD studies: the synthesis of novel phosphaalkenes and the investigation of the reactivities of phosphaalkenes towards various N-heterocyclic carbenes (NHCs) or electrophiles. Chapter 1 serves as a general introduction of the properties and reactivities of phosphaalkenes, N-heterocyclic carbenes and abnormal N-heterocyclic carbenes. Chapter 2 describes the kinetic studies of the abnormal reactions between IMes with MesP=CPh₂, MesP=C(4-C₆H₄F)₂ and MesP=C(4-OMeC₆H₄)₂, respectively. The kinetic and thermodynamic data are calculated in order to compare with DFT calculations. During the study, it is noticed the abnormal reaction is catalyzed by a base whereas hindered by an acid. In Chapter 3, metathesis reactions of phosphaalkenes (MesP=CPh₂, PhP=CPh₂ and o-TolP=CPh₂) mediated by NHCs are discussed. This features the first discovery of the metathesis of a P=C bond. In addition, several novel NHC−phosphinidenes adducts are synthesized from the reactions between NHCs and PhP=CPh₂, o-TolP=CPh₂. Chapter 4 discusses the synthesis of several new phosphaalkenes. These phosphaalkenes are designed in an effort to explore the isolable monomers for the polymerization of P=C bonds. Amongst these phosphaalkenes, (TMOP)P=CPh₂, ArFP=CPh₂ and PhP=C(PhNEt₂)₂ are noticeably stable as monomers whereas PhP=C(PhOMe)₂ and PhP=CPh(PhNEt₂) dimerize as 1,2-diphosphetanes in the solid state. In Chapter 5, the novel addition reactions between various phosphaalkenes and a cationic cyclophosphine [(Lc)₄P₄]⁴⁺ (Lc = Me₂IⁱPr) to afford three-membered rings featuring a P−P bond are described. Furthermore, preliminary results regarding the conversion of the cationic cyclophosphine to potential phospha-Wittig reagents and the study of their reactivities are also presented. Finally, Chapter 6 serves to summarize this thesis work.

description: A machine-learned system that is fair in static decision-making tasks may have biased societal impacts in the long-run. This may happen when the system interacts with humans and feedback patterns emerge, reinforcing old biases in the system and creating new biases. While existing works try to identify and mitigate long-run biases through smart system design, we introduce techniques for monitoring fairness in real time. Our goal is to build and deploy a monitor that will continuously observe a long sequence of events generated by the system in the wild, and will output, with each event, a verdict on how fair the system is at the current point in time. The advantages of monitoring are two-fold. Firstly, fairness is evaluated at run-time, which is important because unfair behaviors may not be eliminated a priori, at design-time, due to partial knowledge about the system and the environment, as well as uncertainties and dynamic changes in the system and the environment, such as the unpredictability of human behavior. Secondly, monitors are by design oblivious to how the monitored system is constructed, which makes them suitable to be used as trusted third-party fairness watchdogs. They function as computationally lightweight statistical estimators, and their correctness proofs rely on the rigorous analysis of the stochastic process that models the assumptions about the underlying dynamics of the system. We show, both in theory and experiments, how monitors can warn us (1) if a bank's credit policy over time has created an unfair distribution of credit scores among the population, and (2) if a resource allocator's allocation policy over time has made unfair allocations. Our experiments demonstrate that the monitors introduce very low overhead. We believe that runtime monitoring is an important and mathematically rigorous new addition to the fairness toolbox.

description: Consider that an incident plane wave is scattered by a homogeneous and isotropic magnetic sphere of finite radius. We determine, by means of the rigorous Mie theory, an exact expression for the time-averaged electromagnetic energy within this particle. For magnetic scatterers, we find that the value of the average internal energy in the resonance picks is much larger than the one associated with a scatterer with the same nonmagnetic medium properties. This result is valid even, and specially, for low size parameter values. Expressions for the contributions of the radial and angular field components to the internal energy are determined. For the analytical study of the weak absorption regime, we derive an exact expression for the absorption cross section in terms of the magnetic Mie internal coefficients. We stress that although the electromagnetic scattering by particles is a well-documented topic, almost no attention has been devoted to magnetic scatterers. Our aim is to provide some new analytical results, which can be used for magnetic particles, and empha- size the unusual properties of the magnetic scatters, which could be important in some applications.

description: We report an invisibility carpet cloak device, which is capable of making an object undetectable by visible light. The cloak is designed using quasi conformal mapping and is fabricated in a silicon nitride waveguide on a specially developed nano-porous silicon oxide substrate with a very low refractive index. The spatial index variation is realized by etching holes of various sizes in the nitride layer at deep subwavelength scale creating a local effective medium index. The fabricated device demonstrates wideband invisibility throughout the visible spectrum with low loss. This silicon nitride on low index substrate can also be a general scheme for implementation of transformation optical devices at visible frequency.

description: In the modern world, one of the most severe eye infections brought on by diabetes is known as diabetic retinopathy, which will result in retinal damage, and, thus, lead to blindness. Diabetic retinopathy can be well treated with early diagnosis. Retinal fundus images of humans are used to screen for lesions in the retina. However, detecting DR in the early stages is challenging due to the minimal symptoms. Furthermore, the occurrence of diseases linked to vascular anomalies brought on by DR aids in diagnosing the condition. Nevertheless, the resources required for manually identifying the lesions are high. Similarly, training for Convolutional Neural Networks is more time-consuming. This proposed research aims to improve diabetic retinopathy diagnosis by developing an enhanced deep learning model for timely DR identification that is potentially more accurate than existing CNN-based models. The proposed model will detect various lesions from retinal images in the early stages. First, characteristics are retrieved from the retinal fundus picture and put into the EDLM for classification. For dimensionality reduction, EDLM is used. Additionally, the classification and feature extraction processes are optimized using the stochastic gradient descent optimizer. The EDLM effectiveness is assessed on the KAG GLE dataset with 3459 retinal images, and results are compared over VGG16, VGG19, RESNET18, RESNET34, and RESNET50.
Qual è l’età della maestra? Come instaurare un nuovo contratto didattico maggiormente favorevole al processo di risoluzione di problemi

description: Il mio intento di ricerca era quello di studiare il sistema didattico e le pratiche di insegnamentoapprendimento per evidenziare quali effetti potessero avere certi atteggiamenti del docente, nel far evolvere la capacità di problem solving degli allievi. L’indagine ha dimostrato che, inizialmente, era presente un forte contratto didattico, basato su alcune regole implicite. Soltanto un bambino su 15, infatti, si è fatto carico della rottura affermando che le due situazioni proposte non si potessero risolvere. Secondo il paradigma della ricerca-azione ho proposto un percorso mirato, di 15 interventi, che si è sviluppato nell’arco di due mesi allo scopo di instaurare nella classe, una terza elementare, un nuovo contratto didattico esplicito, più favorevole alle attività di problem solving. Ho indagato l’evoluzione di tale contratto e dell’atteggiamento degli allievi, analizzando sia le loro produzioni che le discussioni collettive. Ho osservato in particolare quali, tra le strategie comunicative da me adottate, fossero maggiormente efficaci nel favorire una loro presa di responsabilità. Il tipo di analisi è stato sia quantitativo che qualitativo. Anche se statisticamente poco significativa e quindi non generalizzabile, la ricerca ha permesso di evidenziare alcuni risultati interessanti: la messa in atto e lo sviluppo di un nuovo contratto didattico e un’evoluzione positiva delle strategie risolutive e dell’atteggiamento dei bambini di fronte ai problemi proposti.

description: We conceptually unify the description of resonances existing at metallic nanoparticles and optical nanowire antennas. To this end the nanoantenna is treated as a Fabry-Perot resonator with arbitrary semi-nanoparticles forming the terminations. We show that the frequencies of the quasi-static dipolar resonances of these nanoparticles coincide with the frequency where the phase of the complex reflection coefficient of the fundamental propagating plasmon polariton mode at the wire termination amounts to $π$. The lowest order Fabry-Perot resonance of the optical wire antenna occurs therefore even for a negligible wire length. This approach can be used either to easily calculate resonance frequencies for arbitrarily shaped nanoparticles or for tuning the resonance of nanoantennas by varying their termination.

Galilean-invariant scalar fields can strengthen gravitational lensing

description: The mystery of dark energy suggests that there is new gravitational physics on long length scales. Yet light degrees of freedom in gravity are strictly limited by Solar System observations. We can resolve this apparent contradiction by adding a Galilean-invariant scalar field to gravity. Called Galileons, these scalars have strong self-interactions near overdensities, like the Solar System, that suppress their dynamical effect. These nonlinearities are weak on cosmological scales, permitting new physics to operate. In this Letter, we point out that a massive gravity inspired coupling of Galileons to stress energy gravity can have a surprising consequence: enhanced gravitational lensing. Because the enhancement appears at a fixed scaled location for a wide range of dark matter halo masses, stacked cluster analysis of weak lensing data should be able to detect or constrain this effect.

description: We consider the nonrelativistic particle moving on noncommutative space-time in the presence of constant force $\vec{F}$. Further, following the paper M. Daszkiewicz, C.J. Walczyk, Phys. Rev. D 77, 105008 (2008); arXiv: 0802.3575 [math-ph], we recall that the considered noncommutativity generates additional force terms, which appear in the corresponding Newton equation. We demonstrate that the same force terms can be generated by the proper noninertial transformation of classical nonrelativistic space-time.

description: Hydrogen production in the microfluidic alkaline membraneless electrolyzer (μAME) marks a new paradigm in sustainable energy technology. One challenge in this field is implementing a bifunctional catalyst to catalyze hydrogen evolution reaction and oxygen evolution reaction using methods compatible with microfabrication techniques. Herein, the scalable synthesis, micropatterning, and performance of a nickel nitride (Ni3N/Ni) bifunctional catalyst are demonstrated. Microfabrication is used to pattern Ni microelectrodes, and nitridation and N–H grafting of the electrodes—which also act as the catalysts—are achieved by ammonia plasma. These electrodes are incorporated into the μAME device, and the electrolyte flow rate is optimized to maximize gas product separation. The μAME is operated in a two-electrode configuration exhibiting a current density of 263.73 mA cm–2 at 2.5 V and a stable 6 h operation for overall water splitting. The μAME performance efficiency is 99.86%, with a current density of 150 mA cm–2. Gas chromatography of the electrolysis products revealed no gas cross-over across the electrodes. Volumetric collection efficiencies of 97.72% for H2 and 96.14% for O2 are obtained. The performance of the μAME is comparable to a membrane-based electrolyzer operating under stringent conditions of high temperature (60–80 °C) and extreme electrolyte pH (30–40 wt % KOH).

description: Single-crystal growth, magnetic properties, and magnetocaloric effect of the $S = 3/2$ kagome ferromagnet Li$_9$Cr$_3$(P$_2$O$_7$)$_3$(PO$_4$)$_2$ (trigonal, space group: $P\bar{3}c1$) are reported. Magnetization data suggest dominant ferromagnetic intra-plane coupling with a weak anisotropy and the onset of ferromagnetic ordering at $T_{\rm C} \simeq 2.6$ K. Microscopic analysis reveals a very small ratio of interlayer to intralayer ferromagnetic couplings ($J_{\perp}/J \simeq 0.02$). Electron spin resonance data suggest the presence of short-range correlations above $T_{\rm C}$ and confirms quasi-two-dimensional character of the spin system. A large magnetocaloric effect characterized by isothermal entropy change of $-ΔS_{\rm m}\simeq 31$ J kg$^{-1}$ K$^{-1}$ and adiabatic temperature change of $-ΔT_{\rm ad}\simeq 9$ K upon a field sweep of 7 T is observed around $T_{\rm C}$. This leads to a large relative cooling power of $RCP \simeq 284$ J kg$^{-1}$. The large magnetocaloric effect, together with negligible hysteresis render Li$_9$Cr$_3$(P$_2$O$_7$)$_3$(PO$_4$)$_2$ a promising material for magnetic refrigeration at low temperatures. The magnetocrystalline anisotropy constant $K \simeq -7.42 \times 10^4$ erg cm$^{-3}$ implies that the compound is an easy-plane type ferromagnet with the hard axis normal to the $ab$-plane, consistent with the magnetization data.

description: We discuss perturbative O(g^2a) matching with static heavy quarks and domain-wall light quarks for lattice operators relevant to B-meson decays and $B^0$-$\bar{B}^0$ mixing. The chiral symmetry of the light domain-wall quarks does not prohibit operator mixing at O(a) for these operators. The O(a) corrections to physical quantities are non-negligible and must be included to obtain high-precision simulation results for CKM physics. We provide results using plaquette, Symanzik, Iwasaki and DBW2 gluon actions and applying APE, HYP1 and HYP2 link-smearing for the static quark action.

description: Questo lavoro di diploma è nato dalla grande passione per le due materie nelle quali mi sono abilitato, storia e geografia, e dai valori che queste discipline mi hanno insegnato nel corso degli studi e della mia vita. Al di là delle conoscenze disciplinari queste due materie mi hanno permesso di costruire una visione del mondo radicata nel passato ma continuamente in movimento nei confronti delle sfide del futuro, una visione mutevole e pronta al cambiamento. La domanda è questa: può la didattica interdisciplinare aiutare l’allievo a comprendere la tematica dello sviluppo sostenibile? La risposta è stata si. La didattica interdisciplinare ha permesso di avvicinare gli allievi alla tematica rivelando come in prima gli allievi siano più legati all’ambito emotivo, mentre in seconda a quello operativo. Nasce dunque negli allievi una sensibilità che si sposta dalle emozioni alle azioni. Grazie a questo lavoro di diploma ho potuto fare un primo passo in un mondo che intendo esplorare a pieno in tutte le sue sfumature. Relatore: Marco Lupatini. Materie: storia e geografia

description: The stellar cluster GLIMPSE-C01 is a dense stellar system located in the Galactic Plane. Though often referred to in the literature as an old globular cluster traversing the Galactic disk, previous observations do not rule out that it is an intermediate age (less than a few Gyr) disk-borne cluster. Here, we present high-resolution near-infrared spectroscopy of over 50 stars in the cluster. We find an average radial velocity is consistent with being part of the disk, and determine the cluster's dynamical mass to be (8 \pm 3)x10^4 Msun. Analysis of the cluster's M/L ratio, the location of the Red Clump, and an extremely high stellar density, all suggest an age of 400-800Myr for GLIMPSE-C01, much lower than for a typical globular cluster. This evidence therefore leads us to conclude that GLIMPSE-C01 is part of the disk population, and is the most massive Galactic intermediate-age cluster discovered to date.
