Delivery of Messenger RNA to platelets using lipid nanoparticles
Creators: name: Novakowski, Stefanie Kim
Publisher: name: University of British Columbia
Year: 2019

description: Platelets are small, anucleate cells that circulate in the blood stream and mediate hemostasis, inflammation, and angiogenesis. Platelet transfusions are used to treat active bleeding as well as to prevent bleeding during thrombocytopenia or prior to surgery. Yet there are situations where transfusions do not adequately stop bleeding, such as during trauma, which is associated with platelet dysfunction. A method for genetically modifying platelets might enhance their efficacy and lead to new therapeutic uses for platelets. As platelets are anucleate, directly modifying platelets requires messenger RNA (mRNA). Attempts to transfect platelets with mRNA have not been successful, and it is unknown whether lipid-based materials could be used as mRNA transfection agents for platelets. Lipid nanoparticles (LNPs) have been used for nucleic acid delivery in vitro and in vivo. In this thesis, the ability of four different classes of LNPs to deliver mRNA to platelets was compared. These classes consisted of LNPs containing cationic lipids (cLNPs) that are highly effective in vitro, LNPs containing ionizable cationic lipids (icLNPs) developed for in vivo use, LNPs without a cationic lipid commonly used to encapsulate proteins or small molecules, and a commercially available agent previously used for short interfering RNA delivery to platelets. To identify ideal conditions for transfection with mRNA, uptake under various storage conditions and the ability of the LNPs to alter platelet activation was quantified. Finally, the ability of platelets to translate and release the mRNA was assessed. Two approaches were taken for mRNA delivery. In one approach, mRNA was synthesized inside of liposomes, indicating proteins, DNA, and small molecules can be delivered to platelets using LNPs. In the second approach, in vitro transcribed mRNA was directly delivered to platelets using icLNPs and cLNPs, and mRNA delivered to platelets using cLNPs was released in microparticles. These were the first examples of direct delivery of mRNA to platelets, and the first step towards creating genetically modified platelets. While protein synthesis in LNP-treated platelets was not detected, optimizing the LNP formulations used here may lead to a transfection agent for platelets that allows for de novo synthesis of exogenous proteins in the future.

description: DAEPs represent a form of the exclusionary discipline practices used by school districts with zero tolerance policies to remove identified students from home campuses, despite evidence showing the ineffectiveness of such policies. Educational leaders believe alternative education offers an effective method to reduce negative student behaviors in schools. DAEPs are aimed at correcting or managing the behavior of disruptive students. More concerning, students who have been processed through the court system as well as through the disciplinary processes of the school district receive assignments in higher security DAEPs known as Juvenile Justice Alternative Education Programs (JJAEP). An overview of the JJAEP phenomenon’s interventions and transition support programs for students who return to the home school is needed. The purpose of this study was to explore the phenomenon of the JJAEP in Texas from the perspectives of the educational leaders responsible for the instruction within these schools and the transitions of students returning to their home campuses. The inquiry provided a phenomenological understanding of the characteristics of JJAEPS that were expected to offer students individualized academic and behavior supports. To conduct this study, five educational leaders who oversaw one of the 26 JJAEPs in Texas were interviewed in one-on-one format about their lived experiences with this educational phenomenon. The findings produced four themes: (a) Theme 1: JJAEP curriculum and instruction follow district guidelines; (b) Theme 2: JJAEPs focus on social-emotional interventions with students; (c) Theme 3: Minimal implementation opportunities exist to support college, career, and military readiness (CCMR) at a JJAEP; (d) Theme 4: Comprehensive transition planning is undeveloped at a JJAEP. Chapter 5 contains the discussion, implications, and recommendations for future research.

description: We address a central (and classical) issue in the theory of infinite games: the reduction of the memory size that is needed to implement winning strategies in regular infinite games (i.e., controllers that ensure correct behavior against actions of the environment, when the specification is a regular omega-language). We propose an approach which attacks this problem before the construction of a strategy, by first reducing the game graph that is obtained from the specification. For the cases of specifications represented by "request-response"-requirements and general "fairness" conditions, we show that an exponential gain in the size of memory is possible.

description: Die MRT hat sich als wertvolles Diagnosewerkzeug im klinischen Alltag gezeigt und sich seit seiner Einführung konstant weiterentwickelt. So wurde erst kürzlich der erste MRT durch die United States Food and Drug Administration zur klinischen Nutzung freigegeben. Mit einer höheren Magnetfeldstärke ändern sich die physikalischen Effekte und Parameter, die eine positive (kontrastverstärkende Auswirkung), aber auch eine negative (artefaktverstärkende) Auswirkung auf die Bildgebung haben können. So ist es aus technischen Gründen derzeit noch nicht möglich, eine Ganzkörperaufnahme bei einer Feldstärke von 7 T zu generieren, wie es beispielsweise bei 1,5 T möglich ist. Die derzeitige Bildgebung bei 7 T-MRTs beschränkt sich hauptsächlich auf lokale Bereiche wie z.B. das Gehirn, oder das Fuß-, Arm- oder Kniegelenk. Auf Basis der großen Nachfrage aus dem klinischen Bereich, das Bildfeld zu erweitern, ergibt sich die Fragestellung dieser Dissertation: Ist es möglich, mit dem aktuellen Stand der Technik unter Berücksichtigung der maximal verfügbaren Sende- und Empfangskanäle, die ein derzeitiges kommerzielles 7 T-MRT bietet, ein Bildfeld zu generieren, welches den Kopf- und Halsbereich abdeckt? Diese Fragestellung wurde durch die Entwicklung von morphologisch angepassten Signalgeneratoren als auch Signaldetektoren gelöst. Das Bildfeld wurde von der Gehirnregion auf den Halsbereich bei 7 T erweitert. Die entwickelte Hardware wurde entworfen, simuliert, konstruiert, getestet und mit einer kommerziell verfügbaren 7 T Gehirnspule verglichen. Ein Fortschritt zum aktuellen Stand der Technik wurde quantifiziert. Die neu entwickelten Methoden zur Gestaltung und Konstruktion der Sende- und Empfangsstruktur bei 7 T, als auch die zur Prüfung der Funktionalität verwendete Hardware, wurde direkt in abgewandelter Form bei ähnlichen MRT-Forschungsprojekten bei einer Feldstärke von 3 T verwendet und publiziert. Zusammenfassend wurde mit diesem Projekt sowohl der Grundstein für die klinische Bildgebung als auch für weitere Forschung im kombinierten Kopf- und Halsbereich bei der 7 T gelegt. Der Einfluss dieses Projekts wird sich voraussichtlich in den nächsten Jahren in klinischen Studien zeigen. Limitierende Faktoren wie beispielsweise die SAR können durch Softwaremaßnahmen und der Ansteuerung der Spulen in weiteren Doktorarbeiten optimiert werden, um den Bildgebungsprozess zu optimieren.
Physical activity as a modulator of intestinal health and its implications in inflammatory bowel diseases
Creators: name: Estaki, Mehrbod
Publisher: name: University of British Columbia

description: The interactions between humans, the environment, and intestinal microbiota form a tripartite relationship that is fundamental to the overall health of the host. Disruptions in this delicate balance between the microbiota and host immunity are implicated in various chronic diseases including inflammatory bowel disease (IBD). IBD encompassing ulcerative colitis and Crohn’s disease are idiopathic, relapsing chronic inflammatory disorders of the intestinal tract with annual health care burdens of over $1.8 billion in Canada. There is no known cure for IBD, as so, novel therapeutic in its prevention and management are of great interest. Recently, physical activity (PA) has been proposed as a potential therapy in combating IBD. Here we show that higher aerobic fitness in humans is associated with increased bacterial diversity in the gut and higher abundances of butyrate, a type of short-chain fatty acid produced by resident bacteria with known anti-inflammatory properties. We confirm these findings in animal models showing that voluntary wheel running (VWR) in mice increases butyrate production. Additionally, VWR mice show increased microbial diversity, decreased expression of pro-inflammatory (TNF-α, TGF-β, and IFN-γ) and increased expression of anti-inflammatory (IL-10) cytokines suggestive of the potential to be primed against the damaging effects of chronic inflammation. These enhancements however were absent in a life-long model of mucin2 deficient (MUC2-/-) murine colitis and VWR offered no protection in these mice against disease symptoms. Taken together, these suggest that the benefits of PA against IBD are preventative in nature and cannot reverse existing disease states like those found in IBD. We further showed that certain PA-derived changes in the intestines such as microbial community changes, upregulation of IL-10, and attenuation of IFN-γ are dependent on the amount of PA while reduction of anti-inflammatory cytokines TNF-α and TGF-β can occur even under low running conditions. In summary, we showed that PA can beneficially modulate the intestinal environment in healthy hosts, leading to a primed anti-inflammatory state likely effective in IBD management during remission.

description: We investigate the chromospheric evaporation in the flare of 2007 January 16 using line profiles observed by the EUV Imaging Spectrometer (EIS) onboard Hinode. Three points at flare ribbons of different magnetic polarities are analyzed in detail. We find that the three points show different patterns of upflows and downflows in the impulsive phase of the flare. The spectral lines at the first point are mostly blue shifted, with the hotter lines showing a dominant blue-shifted component over the stationary one. At the second point, however, only weak upflows are detected; in stead, notable downflows appear at high temperatures (up to 2.5-5.0 MK). The third point is similar to the second one only that it shows evidence of multi-component downflows. While the evaporated plasma falling back down as warm rain is a possible cause of the redshifts at points 2 and 3, the different patterns of chromospheric evaporation at the three points imply existence of different heating mechanisms in the flaring active region.

description: The simulation software for the ATLAS Experiment at the Large Hadron Collider is being used for large-scale production of events on the LHC Computing Grid. This simulation requires many components, from the generators that simulate particle collisions, through packages simulating the response of the various detectors and triggers. All of these components come together under the ATLAS simulation infrastructure. In this paper, that infrastructure is discussed, including that supporting the detector description, interfacing the event generation, and combining the GEANT4 simulation of the response of the individual detectors. Also described are the tools allowing the software validation, performance testing, and the validation of the simulated output against known physics processes.

description: We introduce synchronizing objectives for Markov decision processes (MDP). Intuitively, a synchronizing objective requires that eventually, at every step there is a state which concentrates almost all the probability mass. In particular, it implies that the probabilistic system behaves in the long run like a deterministic system: eventually, the current state of the MDP can be identified with almost certainty. We study the problem of deciding the existence of a strategy to enforce a synchronizing objective in MDPs. We show that the problem is decidable for general strategies, as well as for blind strategies where the player cannot observe the current state of the MDP. We also show that pure strategies are sufficient, but memory may be necessary.

description: In this work we study the convex set of quantum states from a quantum logical point of view. We consider an algebraic structure based on the convex subsets of this set. The relationship of this algebraic structure with the lattice of propositions of quantum logic is shown. This new structure is suitable for the study of compound systems and shows new differences between quantum and classical mechanics. This differences are linked to the nontrivial correlations which appear when quantum systems interact. They are reflected in the new propositional structure, and do not have a classical analogue. This approach is also suitable for an algebraic characterization of entanglement.

description: Das prärenale ANV nach infarktinduziertem kardiogenem Schock ist noch immer eine häufige Komplikation mit weiterhin hoher Letalität. Zum aktuellen Zeitpunkt gibt es nur wenige therapeutische Ansätze, um die Prävalenz und Letalität dieser Komplikation zu senken. Die temporäre hämodynamische Unterstützung des Kreislaufes mittels eines mechanischen Pumpsystems ist einer der möglichen Ansätze. Bereits die Studie von Flaherty und Kollegen aus dem Jahr 2017 zeigte die positiven renalen Auswirkungen der mechanischen Herzunterstützung mittels einer Impella-Mikroaxialpumpe bei hospitalisierten kritisch kranken Patienten und Patientinnen. Die Impella-Systeme gehören zu den intrakorporal gelegenen linksventrikulären mechanischen Herzunterstützungssystemen. Dabei entlasten die Systeme mittels des kontinuierlichen Bluttransportes vom linken Ventrikel in die Aorta das kardiale System und führen zu einer Verbesserung der Perfusion aller Endorgane. Frühere Studien untersuchten die Verbesserung der renalen Perfusion durch die Unterstützung des HZV mittels einer Impella-Mikroaxialpumpe jedoch nur anhand der Kreatinin-Blutanalyse sowie Diurese des Patienten oder Patientinnen. Unsere Studie nutzte als erstes die sonographische RRI-Detektion um den positiven Einfluss der mechanischen Herzunterstützung auf das renale System nachzuweisen. Dabei könnte die sonographische Messung des RRI den hämodynamischen Einfluss der Impella-Mikroaxialpumpe spezifischer und störungsfreier als die Blutanalyse des Kreatinins abbilden. Unsere Ergebnisse zeigten eine signifikante Senkung des RRI durch Steigerung des HZV durch die mechanische Herzunterstützung. Eine Steigerung der Impella-Leistung um +0,5 L/min zeigte bereits eine signifikante (p< 0,001) Reduktion des RRI um 0,07 (9,6%). Die Leistungssteigerung auf +1,0 L/min erbrachte sogar eine signifikante (p< 0,001) Reduktion des RRI um 0,115 (15,74%). Der positive Einfluss der Impella-Mikroaxialpumpe auf die renale Perfusion konnte daher auch mittels der RRI-Detektion nachgewiesen werden und sollte als möglicher Ansatz der Reduktion renaler Komplikationen im kardiogenen Schock angesehen werden.

We characterize the universal features of the trap-size dependence using scaling arguments. The resulting scenario is supported by numerical Monte Carlo simulations of a classical two-dimensional XY model with a space-dependent hopping parameter whose inhomogeneity is analogous to that arising from the trapping potential in experiments of atomic gases.

description: In the UK, 7-10% of the child and adolescent population are currently considered obese according to International Obesity Task Force (IOTF) definitions, and this proportion is expected to rise to 14% over the next 20 years. Childhood obesity is associated with complications including dyslipidemia, insulin resistance, and respiratory problems, and childhood body mass index (BMI) is correlated with BMI in adulthood. However, the ways in which overweight and obesity in early life impact on long-term health are not well understood.This thesis reviews the current evidence for the associations between overweight in childhood and disease outcomes in adulthood, and discusses the limitations of methods that have commonly been used to examine this topic. To investigate the effects of childhood and adolescent overweight on long-term health, pooled data from three British National Birth Cohorts (the 1946 National Survey of Health and Development, 1958 National Child Development Study, and 1970 British Cohort Study) are analysed. The findings of this analysis indicate that being overweight in childhood and adolescence may contribute to increased risk of type 2 diabetes and coronary heart disease, but not hypertension or non-cardiovascular outcomes. Projections from a micro-simulation model show that overweight and obesity in the current UK child population could present a substantial burden in terms of disease prevalence and healthcare costs by the year 2050, and the effects of different obesity interventions on long-term burden are explored.Overweight and obesity in childhood may have important implications for long-term cardiovascular risk, and current trends in childhood obesity prevalence are likely to have a substantial impact on long-term health burden in the UK. Early intervention to reduce overweight in childhood is likely to have an important role in reducing future obesity-related disease burden.

description: The Standard Model (SM) plus a real gauge-singlet scalar field dubbed darkon (SM+D) is the simplest model possessing a weakly interacting massive particle (WIMP) dark-matter candidate. In this model, the parameters are constrained from dark matter relic density and direct searches. The fact that interaction between darkon and SM particles is only mediated by Higgs boson exchange may lead to significant modifications to the Higgs boson properties. If the dark matter mass is smaller than a half of the Higgs boson mass, the Higgs boson can decay into a pair of darkons resulting in a large invisible branching ratio. The Higgs boson will be searched for at the LHC and may well be discovered in the near future. If a Higgs boson with a small invisible decay width will be found, the SM+D model with small dark matter mass will be in trouble. We find that by extending the SM+D to a two-Higgs-doublet model plus a darkon (THDM+D) it is possible to have a Higgs boson with a small invisible branching ratio and at the same time the dark matter can have a low mass. We also comment on other implications of this model.

Investigations on deep learning techniques for property assessment

description: Property assessment plays a vital role in not only people's daily life but also the establishment of policies in North America. Therefore, the robust and accurate assessment is thus required. However, there are several challenges to prevent improving performance in property assessment. For example, the to-be-valued property and its neighbors can influence their values mutually, which is named peer-dependence. Besides, the property values also depend on their topography around the house. Moreover, various urban data in the city, i.e., criminal activities and point of interests, also reflects the property values. The accuracy of property assessment can be further improved if the process can fuse the urban data for assessment. Nowadays, deep learning models become the most powerful computational models in the subjects of both electrical engineering and computer science. Therefore, the thesis aims to investigate deep learning techniques to address three specific challenges in property assessment, which are considering peer-dependence considering topography and considering urban data for improving property assessment. In the first study, a recurrent neural network (RNN), peer-dependence valuation model (PDVM), is proposed to converts the peer-dependence based valuation into sequence prediction. Firstly, K-Nearest similar house sampling (KNSHS) algorithm generates sequences from the to-be-valued property and nearby houses. Then, an RNN estimates the property values from given sequences. The experimental results indicate that PDVM outperforms the other novel computational models being used for property assessment. In the second study, a convolutional neural network (CNN) based method, attention-based multi-modal fusion (AMMF), is proposed to estimate property values with house attributes and corresponding street maps which contain features of topography. The experimental results indicate the proposed method outperforms the contemporary approaches. In the third study, to investigate the ways of urban data fusion to property values, a novel deep learning framework, multi-source urban data fusion (MUDF), is proposed to estimate property values from metadata and street-view images of properties. The experimental results with the data collected from the city of Philadelphia demonstrate the accuracy of the proposed model.

description: In this paper, we take dust matter and investigate static spherically symmetric solution of the field equations in metric f(R) gravity. The solution is found with constant Ricci scalar curvature and its energy distribution is evaluated by using Landau-Lifshitz energy-momentum complex. We also discuss the stability condition and constant scalar curvature condition for some specific popular choices of f(R) models in addition to their energy distribution.

description: In the framework of Kohn-Sham density-functional theory, systems with ground-state densities that are not pure-state v-representable in the non-interacting reference system (PSVR) occur frequently. In the present contribution, a new algorithm, which allows the solution of such systems, is proposed. It is shown that the use of densities which do not correspond to a ground state of their non-interacting reference system is forbidden. As a consequence, the proposed algorithm considers only non-interacting ensemble v-representable densities. The Fe atom, a well-known non-PSVR system, is used as an illustration. Finally, the problem is analyzed within finite temperature density-functional theory, where the physical significance of fractional occupations is exposed and the question of why degenerate states can be unequally occupied is resolved.

description: We study the BPS equations in ABJM theory furthermore. Besides the known funnel solutions which are proposed to describe M2-M5 systems we find a new kind solution. We analyze the properties therein and see that it can describe M2-KK6 (2D membranes with 6D Kaluza-Klein monopole) systems. Our solutions also reveal new vacua in the mass deformed ABJM theory. Contrast to the previous investigation in which the vacua are reducible, ours may be irreducible. We also discuss a possible interpretation of the new BPS solutions as a M2-2M5 system.

description: We demonstrate a quantum key distribution with a secure bit rate exceeding 1 Mbit/s over 50 km fiber averaged over a continuous 36-hours period. Continuous operation of high bit rates is achieved using feedback systems to control path length difference and polarization in the interferometer and the timing of the detection windows. High bit rates and continuous operation allows finite key size effects to be strongly reduced, achieving a key extraction efficiency of 96% compared to keys of infinite lengths.

description: The sound velocity of some liquid elements of groups IV, V and VI, as reported in the literature, displays anomalous features that set them apart from other liquid metals. In an effort to determine a possible common origin of these anomalies, extensive neutron diffraction measurements of liquid Bi and Sb were carried out over a wide temperature range. The structure factors of liquid Sb and Bi were determined as a function of temperature. The structure of the two molten metals was carefully analyzed with respect to peak locations, widths and coordination number in their respective radial distribution function. The width of the peaks in the radial distribution function were not found to increase and even decreased within a certain temperature range. This anomalous temperature dependence of the peak widths correlates with the anomalous temperature dependence of the sound velocity. This correlation may be accounted for by increasing rigidity of the liquid structure with temperature. A phenomenological correlation between the peak width and the sound velocity is suggested for metallic melts and is found to agree with available data for normal and anomalous elemental liquids in groups IV-VI.

description: Many large financial planning models are written in a spreadsheet programming language (usually Microsoft Excel) and deployed as a spreadsheet application. Three groups, FAST Alliance, Operis Group, and BPM Analytics (under the name "Spreadsheet Standards Review Board") have independently promulgated standardized processes for efficiently building such models. These spreadsheet engineering methodologies provide detailed guidance on design, construction process, and quality control. We summarize and compare these methodologies. They share many design practices, and standardized, mechanistic procedures to construct spreadsheets. We learned that a written book or standards document is by itself insufficient to understand a methodology. These methodologies represent a professionalization of spreadsheet programming, and can provide a means to debug a spreadsheet that contains errors. We find credible the assertion that these spreadsheet engineering methodologies provide enhanced productivity, accuracy and maintainability for large financial planning models

description: Das Nebennierenrindenkarzinom geht mit einer schlechten Prognose und hoher Letalität einher. Eine Suppression der lncRNA H19 führt zu einer Herunterregulation von Autophagiemarkern, einer erhöhten Proliferationsrate sowie gesteigertem Metastasierungspotential bei von Nebennierenrindenkarzinom betroffenen Patienten. Die Anwendung der Deacetylaseinhibitoren (DACIs) Panobinostat, Trichostatin A (TSA) und SAHA beeinträchtigt die Zellviabilität von H295R-Monolayern und Sphäroiden und führt zu einer Überexpression von H19 und Autophagietranskripten. Durch einen H19-Knockdown in H295R-Zellen war es nicht möglich, dass Expressionsniveau von Autophagietranskripten zu modulieren. Stattdessen inhibiert ein Knockdown von H19 die Fähigkeit von DACIs, das Proteinniveau von Autophagiemarkern zu modulieren. Außerdem kann durch eine höhere Konzentration von DACIs die Proteinquantität von Beclin1 und SQSTM1/p62 reduziert werden sowie die Konversion von LC3BI in LC3BII induziert werden, wodurch sich ein aktiver Autophagieprozess bestätigt. Weder die Proteinquantität noch die Aktivität von Caspase 8 und 3/7 werden durch DACis verändert, sodass die Involvierung von Apoptose am NCI-H295R-Zelluntergang ausgeschlossen werden kann. DACIs stellen die H19-Expression und die Expression von Autophagiemarkergenen wieder her und lösen Zelltod in Nebennierenrindenkarzinomzellen aus. Die Wiederaktivierung von Autophagie könnte eine neue Strategie für die Behandlung von Patienten bedeuten, die von dieser schwerbehandelbaren malignen Erkrankung betroffen sind.

Ensemble v-representable ab-initio density functional calculation of energy and spin in atoms: atest of exchange-correlation approximations

description: The total energies and the spin states for atoms and their first ions with Z = 1-86 are calculated within the the local spin-density approximation (LSDA) and the generalized-gradient approximation (GGA) to the exchange-correlation (xc) energy in density-functional theory. Atoms and ions for which the ground-state density is not pure-state v-representable, are treated as ensemble v- representable with fractional occupations of the Kohn-Sham system. A newly developed algorithm which searches over ensemble v-representable densities [E. Kraisler et al., Phys. Rev. A 80, 032115 (2009)] is employed in calculations. It is found that for many atoms the ionization energies obtained with the GGA are only modestly improved with respect to experimental data, as compared to the LSDA. However, even in those groups of atoms where the improvement is systematic, there remains a non-negligible difference with respect to the experiment. The ab-initio electronic configuration in the Kohn-Sham reference system does not always equal the configuration obtained from the spectroscopic term within the independent-electron approximation. It was shown that use of the latter configuration can prevent the energy-minimization process from converging to the global minimum, e.g. in lanthanides. The spin values calculated ab-initio fit the experiment for most atoms and are almost unaffected by the choice of the xc-functional. Among the systems with incorrectly obtained spin there exist some cases (e.g. V, Pt) for which the result is found to be stable with respect to small variations in the xc-approximation. These findings suggest a necessity for a significant modification of the exchange-correlation functional, probably of a non-local nature, to accurately describe such systems. PACS numbers: 31.15.A

description: We elucidate the case in which the Ablowitz-Ladik (AL) type discrete nonlinear SchrÄodinger equa- tion (NLSE) on simple networks (e.g., star graphs and tree graphs) becomes completely integrable just as in the case of a simple 1-dimensional (1-d) discrete chain. The strength of cubic nonlinearity is different from bond to bond, and networks are assumed to have at least two semi-infinite bonds with one of them working as an incoming bond. The present work is a nontrivial extension of our preceding one (Sobirov et al, Phys. Rev. E 81, 066602 (2010)) on the continuum NLSE to the discrete case. We find: (1) the solution on each bond is a part of the universal (bond-independent) AL soliton solution on the 1-d discrete chain, but is multiplied by the inverse of square root of bond-dependent nonlinearity; (2) nonlinearities at individual bonds around each vertex must satisfy a sum rule; (3) under findings (1) and (2), there exist an infinite number of constants of motion. As a practical issue, with use of AL soliton injected through the incoming bond, we obtain transmission probabilities inversely proportional to the strength of nonlinearity on the outgoing bonds.
