description: Given a linear system in a real or complex domain, linear regression aims to recover the model parameters from a set of observations. Recent studies in compressive sensing have successfully shown that under certain conditions, a linear program, namely, l1-minimization, guarantees recovery of sparse parameter signals even when the system is underdetermined. In this paper, we consider a more challenging problem: when the phase of the output measurements from a linear system is omitted. Using a lifting technique, we show that even though the phase information is missing, the sparse signal can be recovered exactly by solving a simple semidefinite program when the sampling rate is sufficiently high, albeit the exact solutions to both sparse signal recovery and phase retrieval are combinatorial. The results extend the type of applications that compressive sensing can be applied to those where only output magnitudes can be observed. We demonstrate the accuracy of the algorithms through theoretical analysis, extensive simulations and a practical experiment.

Surface properties of crandallite in relation to froth flotation
Creators: name: Kaushik, Sarthak
Publisher: name: University of British Columbia
Year: 2012

description: The surface properties of crandallite relevant to the anionic flotation of salt-type minerals were investigated through electrokinetic, turbidity, and wettability techniques. All the tests were performed on fine crandallite particles as a function of pH and reagent concentration. The selected reagents included starch and oleic acid. From the zeta potential measurements, the iso-electric point of crandallite was found to be at pH 5.5 and the mineral surface can be expected to be negatively charged under typical flotation conditions (pH 9-11). The value of the iso-electric point correlated well with the stability of crandallite particles towards aggregation. Suspensions of fine crandallite showed minimum turbidity at pH 5.5 suggesting that the aggregation of the mineral was most pronounced at the iso-electric point. Calcium ions behaved as potential determining ions by increasing the iso-electric point to pH 6.5. In addition, calcium ions also acted as specifically adsorbing ions at higher pH. In the presence of starch, crandallite particles were strongly flocculated producing supernatants with the clarity of tap water. At the same time, the effect of starch on the zeta potential of crandallite was rather weak, consistent with the non-ionic character of the polysaccharide. The stability of crandallite towards aggregation was not strongly affected by oleic acid suggesting that the surfactant did not interact with the mineral. Wettability measurements on crandallite particles showed that oleic acid did not render the mineral particles hydrophobic at pH 10.5 (under normal flotation conditions) or at pH 7, which was in strong contrast to the wettability response of apatite. Under these conditions, crandallite surface was negatively charged and the adsorption of the anionic surfactant seemed to involve physical electrostatic forces as opposed to chemical interactions known to occur between apatite and oleic acid. Overall, the experimental results strongly suggest that crandallite remains hydrophilic during apatite flotation at pH 10.5 and the main mechanism of contamination of apatite concentrates by crandallite is through mechanical entrainment in the froth rather than by true flotation. In this respect, the role of starch as a flocculant should be beneficial in reducing the amount of fine crandallite reporting to the apatite concentrate.

description: Reconstructed jets in heavy ion collisions are a crucial tool for understanding the quark-gluon plasma. The separation of jets from the underlying event is necessary particularly in central heavy ion reactions in order to quantify medium modifications of the parton shower and the response of the surrounding medium itself. There have been many methods proposed and implemented for studying the underlying event substructure in proton-proton and heavy ion collisions. In this paper, we detail a method for understanding underlying event contributions in Au+Au collisions at $\sqrt{s_{NN}}$ = 200 GeV utilizing the HIJING event generator. This method, extended from previous work by the ATLAS collaboration, provides a well-defined association of "truth jets" from the fragmentation of hard partons with "reconstructed jets" using the anti-$k_T$ algorithm. Results presented here are based on an analysis of 750M minimum bias HIJING events. We find that there is a substantial range of jet energies and radius parameters where jets are well separated from the background fluctuations (often termed "fake jets") that make jet measurements at RHIC a compelling physics program.

description: Fix integers $b>a\geq1$ with $g:=\gcd(a,b)$. A set $S\subseteq\mathbb{N}$ is \emph{$\{a,b\}$-multiplicative} if $ax\neq by$ for all $x,y\in S$. For all $n$, we determine an $\{a,b\}$-multiplicative set with maximum cardinality in $[n]$, and conclude that the maximum density of an $\{a,b\}$-multiplicative set is $\frac{b}{b+g}$. For $A, B \subseteq \mathbb{N}$, a set $S\subseteq\mathbb{N}$ is \emph{$\{A,B\}$-multiplicative} if $ax=by$ implies $a = b$ and $x = y$ for all $a\in A$ and $b\in B$, and $x,y\in S$. For $1 < a < b < c$ and $a, b, c$ coprime, we give an O(1) time algorithm to approximate the maximum density of an $\{\{a\},\{b,c\}\}$-multiplicative set to arbitrary given precision.
Taphonomic comparison of Hypacrosaurus stebingeri (Hadrosauridae: Lambeosaurinae) bonebeds from the upper Campanian Oldman and Two Medicine formations of Alberta and Montana

description: Hadrosaurid social structure is still poorly understood. Evidence from bonebeds suggests that juvenile individuals lived apart from herds composed of older individuals, a phenomenon called age segregation. However, the timing at which juvenile individuals became segregated and later rejoined a multigenerational herd is still unknown. Three monodominant bonebeds that preserve the remains of multiple individuals of the lambeosaurine hadrosaurid Hypacrosaurus stebingeri at different ontogenetic stages offer an opportunity to better understand the timing of the age structuring in this species’ social structure. One of the three bonebeds, known as the Devil’s Coulee juvenile hadrosaur bonebed (JBB) from the Oldman Formation of Alberta (Canada), studied here for the first time, preserves a minimum of four similar-sized late juvenile individuals. The two other bonebeds, Blacktail Creek North (BCN) and Lambeosite (LS) from the Two Medicine Formation of Montana (U.S.A.), preserve a minimum of 23 nestling individuals, and four similar-sized late juvenile individuals with one adult, respectively. These bonebeds show uniform taphonomic signatures throughout the assemblage, characterized by little to no weathering and abrasion, uniform style of fracturing, and rare tooth marks in the assemblages. All three bonebeds are interpreted as mass-mortality assemblages. Histological data indicates that the late juvenile individuals from the JBB were three years old at the time of death, similar to the slightly larger late juvenile individuals from the LS, whereas the individuals from the BCN were less than one year old. A taphonomic comparison with osteological considerations of the three bonebeds reveal that Hypacrosaurus stebingeri individuals became segregated when they were less than one year old, and rejoined a multigenerational herd when they were three years old, as evidenced by the presence of an adult with four three-year-old individuals in the LS. Furthermore, the smaller number of individuals associated with later ontogenetic stages reveals that group size appears to decrease as Hypacrosaurus stebingeri individuals grew older.

description: The network approach became a widely used tool to understand the behaviour of complex systems in the last decade. We start from a short description of structural rigidity theory. A detailed account on the combinatorial rigidity analysis of protein structures, as well as local flexibility measures of proteins and their applications in explaining allostery and thermostability is given. We also briefly discuss the network aspects of cytoskeletal tensegrity. Finally, we show the importance of the balance between functional flexibility and rigidity in protein-protein interaction, metabolic, gene regulatory and neuronal networks. Our summary raises the possibility that the concepts of flexibility and rigidity can be generalized to all networks.

description: Local measurements on bipartite maximally entangled states can yield correlations that are maximally nonlocal, monogamous, and associated to fully random outcomes. This makes these states ideal for bipartite cryptographic tasks. Genuine-multipartite nonlocality constitutes a stronger notion of nonlocality that appears in the multipartite case. Maximal genuine-multipartite nonlocality, monogamy and full random outcomes are thus highly desired properties for multipartite correlations in intrinsically genuine-multipartite cryptographic scenarios. We prove that local measurements on Greenberger-Horne-Zeilinger states, for all local dimension and number of parts, can produce correlations that are fully genuine-multipartite nonlocal, monogamous and with fully random outcomes. A key ingredient in our proof is a multipartite chained Bell inequality detecting genuine-multipartite nonlocality, which we introduce. Finally, we discuss the applications of our results for intrinsically genuine-multipartite cryptographic protocols such as device-independent secret sharing.

description: This paper aims to analyse the classification of unilateral transfers under the current account at Bretton Woods despite significant opposition from larger delegations of major Allied powers, bringing to the forefront the global liquidity of remittances in the post-War years permitted by their fully currency convertible nature. Using the example of the Indian State of Kerala, this paper charts the relevance of their sustained uninterrupted flow to their subsequent exponential growth in the last three decades, using the case study as a pivot to argue for better policy measures that maximise their multiplier effect.

description: The Swift GRB satellite is an excellent facility for studying novae. Its rapid response time and sensitive X-ray detector provides an unparalleled opportunity to investigate the previously poorly sampled evolution of novae in the X-ray regime. This paper presents Swift observations of 52 Galactic/Magellanic Cloud novae. We included the XRT (0.3-10 keV) X-ray instrument count rates and the UVOT (1700-8000 Angstroms) filter photometry. Also included in the analysis are the publicly available pointed observations of 10 additional novae the X-ray archives. This is the largest X-ray sample of Galactic/Magellanic Cloud novae yet assembled and consists of 26 novae with super soft X-ray emission, 19 from Swift observations. The data set shows that the faster novae have an early hard X-ray phase that is usually missing in slower novae. The Super Soft X-ray phase occurs earlier and does not last as long in fast novae compared to slower novae. All the Swift novae with sufficient observations show that novae are highly variable with rapid variability and different periodicities. In the majority of cases, nuclear burning ceases less than 3 years after the outburst begins. Previous relationships, such as the nuclear burning duration vs. t_2 or the expansion velocity of the eject and nuclear burning duration vs. the orbital period, are shown to be poorly correlated with the full sample indicating that additional factors beyond the white dwarf mass and binary separation play important roles in the evolution of a nova outburst. Finally, we confirm two optical phenomena that are correlated with strong, soft X-ray emission which can be used to further increase the efficiency of X-ray campaigns.

Structural Behaviour of Masonry Arch Retaining Walls

description: Recently, a novel experiment explored the possibility of employing low-rise arch masonry walls to resist earth pressure. The system proved to have several advantages: minimal deflection, ease of construction, cost-effectiveness, and aesthetic appearance. The authors established that the idea could work but did not study the influence of any of the parameters involved. To address this limitation and to further investigate the performance of arch masonry retaining walls, six masonry arch walls were constructed using half-scale concrete blocks and modular cored bricks. The test walls had an equivalent span of 2 m and two different span-to-rise ratio, 0.17 and 0.35. The walls were built inside a rigid concrete tank, and the arch bases were cemented to the concrete base with a mortar joint. Arches were subjected to soil pressure and surcharge load: displacements and strains were measured. The walls demonstrated stability and maintained their structural integrity without significant lateral deformations. The experiment yielded successful results, as the arch masonry walls exhibited deflections less than 0.1% of the backfill height. A simplified finite element micromodel has been developed using ABAQUS software to simulate and study the structure in detail, allowing variation of the parameters intrinsic to such walls. The influences of the rise-to-span ratio, height, and grouting pattern on the performance of the arch were explored. For a given wall width, a curved hollow arch wall profile was found to increase the maximum sustained pressure more so than grouting a flat wall: for the same height and span, a curved hollow arched wall with a rise-to-span ratio of 0.25 resisted 37% more pressure than a grouted planar wall. Thus, by combining the information obtained from the experiment and the numerical modelling, masonry arch retaining walls may be seen as an economical and stable alternative to conventional methods of constructing earth-retaining structures.

The phenomenon of screening of the Coulomb potential by a superstrong magnetic field which has been discovered recently acts in the opposite direction and prevents the nuclei with Z<52 from becoming critical. For Z>52 for a nucleus to become critical stronger B are needed than without taking screening into account.

We discuss the cosmological model that arises in this context and test it against observations of the first acoustic peak in the cosmic microwave background (CMB) anisotropy spectrum, the Hubble diagram for supernovas of type Ia (SNIa), the distance scale of baryonic acoustic oscillations (BAO) and the distribution of large scale structures (LSS). We show that a good concordance is obtained, albeit with a higher value of the present matter abundance than in the ΛCDM model. We also comment on general features of the CMB anisotropy spectrum and on the cosmic coincidence problem.

This talk takes us inside the Secretariat to meet some of the men (and one woman) who headed up its different sections, delving into the records of their internal “kitchen cabinet” meetings to uncover what they themselves thought they were doing.  The League’s high officials talked freely among themselves about the nature and scope of their authority, about how to balance national loyalties and international service, and about how to deal with public complaints of ineffectuality or lack of accountability.  Self-consciously, unevenly and buffeted by political winds, they nonetheless developed strategies and practices that challenged and changed the international system and that still influence it to this day.  Historians and political theorists should pay more attention to the Secretariat as a site for political innovation and political thought.

description: Control and learning are essential to technological advancement, both in the classical and quantum domains, yet their interrelationship is insufficiently clear in the literature, especially between classical and quantum definitions of control and learning. In this thesis, we aim to construct a framework that formally relates learning and control, both classical and quantum, to each other, with this formalism showing how learning can aid control. We formulate new versions of quantum learning and control that essentially quantise classical learning and control, respectively. Furthermore, our framework helps identify interesting unsolved problems in the nexus of classical and quantum control and learning and helps choose tools to solve problems. Our unification of these fields relies on diagrammatically representing the state of knowledge, which elegantly summarises existing knowledge and exposes knowledge gaps. As use cases, we cast the well-studied problem of adaptive quantum-enhanced interferometric phase estimation as a supervised learning problem for devising feasible control policies and develop effective quantum control for two-qubit gate design with trapped ions. Informed by the knowledge that the plant, i.e.~ion trap, is a channel, we develop a comprehensive model of controlled open-system dynamics described by a quantum master equation and validate our model based on empirical data gathered from a control system for preparing Bell states. We then employ global optimisation to design pulse sequences for achieving a robust, rapid two-qubit gate for a chain of seven trapped $^{171}$Yb$^{+}$ ions by optimising over numerically integrated quantum master equation solutions. We further explore the nexus of classical and quantum learning through hybrid classical-quantum learning algorithms. We introduce the ``analogue-quantum kitchen sinks'' algorithm, a quantum extension of the classical "random kitchen sinks," which employs an analogue-quantum computer for mapping data features into new features in a non-linear manner. A classical algorithm can then perform machine learning tasks using the new features. We show the effectiveness of our algorithm for performing binary classification on both a synthetic and a real-world data set through computer simulation of a quantum annealer's operation.

description: Examination of loading the isotopes $^{85}$Rb and $^{87}$Rb simultaneously into a shallow far-off-resonance trap (FORT) has revealed an unexpected decrease in maximum atom number loaded as compared to loading either isotope alone. The simultaneous loading of the FORT will be affected by additional homonuclear and heteronuclear light-assisted collisional losses. However, these losses are measured and found to be insufficient to explain the observed drop in total number of atoms loaded into the FORT. We find that our observations are consistent with a decrease in loading rate caused by inter-isotope disruptions of the efficient laser cooling required to load atoms into the optical trap.

description: Australia’s handling of the COVID-19 pandemic in 2020 will require significant reflection, scrutiny and systems-based reform because there were avoidable deaths, particularly in residential aged care facilities (‘RACFs’). The deaths in Newmarch House in Sydney in April – May 2020 made it the first RACF subjected to scrutiny by the media (an ABC investigation), and the Royal Commission into Aged Care Quality and Safety’s COVID-19 focused hearings and report. It will also be the subject of a coronial inquest in 2022. This article uses Newmarch House as an illustration of the regulatory and governmental system-wide failure to adequately protect the human rights of residents in RACFs. It is argued that the current system of monitoring by the Aged Care Quality and Safety Commission is deficient and that reactive mechanisms, including Royal Commissions and inquests, have significant limitations. Australia should therefore follow the lead of New Zealand and extend the Optional Protocol to the Convention against Torture and Other Cruel, Inhuman or Degrading Treatment or Punishment (‘OPCAT’) monitoring regime to RACFs. This would provide residents of RACFs deprived of their liberty with the same preventive protections afforded by the OPCAT to all Australians deprived of liberty. This is protection that such residents are legally entitled to under the OPCAT.

description: An identifying code of a graph is a subset of its vertices such that every vertex of the graph is uniquely identified by the set of its neighbours within the code. We study the edge-identifying code problem, i.e. the identifying code problem in line graphs. If $\ID(G)$ denotes the size of a minimum identifying code of an identifiable graph $G$, we show that the usual bound $\ID(G)\ge \lceil\log_2(n+1)\rceil$, where $n$ denotes the order of $G$, can be improved to $Θ(\sqrt{n})$ in the class of line graphs. Moreover, this bound is tight. We also prove that the upper bound $\ID(\mathcal{L}(G))\leq 2|V(G)|-5$, where $\mathcal{L}(G)$ is the line graph of $G$, holds (with two exceptions). This implies that a conjecture of R. Klasing, A. Kosowski, A. Raspaud and the first author holds for a subclass of line graphs. Finally, we show that the edge-identifying code problem is NP-complete, even for the class of planar bipartite graphs of maximum degree~3 and arbitrarily large girth.
A Model for Tri-bimaximal Mixing from a Completely Broken $A_4$

description: We propose a new $A_4$ model in which both the right-handed neutrinos and right-handed charged leptons transform as $A_4$ singlets. We reproduce tri-bimaximal mixing pattern exactly although the $A_4$ symmetry is broken completely at leading order in both the neutrino and charged lepton sectors. The charged lepton mass hierarchies are controlled by the spontaneous breaking of the flavor symmetry. The light neutrino spectrum is predicted to be of normal type and the lightest neutrino is massless at leading order. Although the reactor angle $θ_{13}$ is expected to be of order $λ^2_c$ from the next to leading order corrections, this model cannot be ruled out by current experimental data including the latest T2K results. Leptogenesis is realized via the resonant leptogenesis of the second and the third heavy right-handed neutrinos which are degenerate at leading order. The phenomenological consequences for lepton flavor violation are discussed in detail.

description: Effective and efficient healing of wounds is crucial for preventing complications such as infection, delayed recovery, increased scarring, and even death of the organism. My research investigated the role of proteoglycan 4 (PRG4) in wound healing and regeneration. The research employed a multifaceted approach, utilizing a large animal model, transgenic murine models, and mammalian cell culture to elucidate the involvement of PRG4 in maintaining tissue homeostasis across various tissue types. Chapter 2 delved into the impact of recombinant human PRG4 (rhPRG4) treatment on skin wound healing, utilizing a clinically relevant porcine full-thickness skin wound model. These results demonstrated that topical application of rhPRG4 modulates molecular pathways associated with wound healing, leading to reduced fibrosis, enhanced angiogenesis, and the retention of adipocytes at the wound site. Interestingly, a transient increase in adipose tissue during the early stages of wound healing was observed. In Chapter 3, the study explored the impact of rhPRG4 on porcine adipocytes, revealing its role as a potent activator of PPARγ and an inducer of adipogenesis in vitro. This collaboration with Myo Palate Corporation investigated novel approaches for cultivating adipose tissue for cellular agriculture purposes. While rhPRG4 showed potential as an adipocyte inducer, its regulatory approval as a food-safe substance remained a hurdle for cultured meat production. The chapter also presented alternative, food-safe PPARγ agonists, which in combination with insulin, demonstrated high lipid yields for cultured adipocytes. Chapter 4 utilized lineage-tracing transgenic mouse models to explore Hic1+ mesenchymal progenitors and their connection with PRG4. Conditional deletion of Prg4 in these cells impacted tissue regeneration in both articular cartilage and bone. Mesenchymal Hic1+ progenitors, expressing PRG4, play an active role in the wound healing response, as evidenced by their presence at injury sites. Prg4-deficiency in these progenitors negatively affected endogenous PRG4 expression, leading to increased apoptosis and influencing various aspects of bone healing, including osteogenesis, bone turnover, and remodeling. This research sheds light on the intricate interplay between PRG4, tissue-resident mesenchymal progenitors, and the wound healing process, providing valuable insights for the development of targeted therapeutic interventions to enhance tissue repair and regeneration.

description: Background: The concept of patient navigation (PN) was first envisioned to assist marginalized cancer patients access appropriate and timely healthcare resources. While this understanding of PN may still hold for a subgroup of programs today, the expansion of PN over the past 30 years has resulted in a diverse set of interventions with distinct care settings, patient eligibility criteria, navigator training, and program objectives. Noting this, our study sought to better understand how PN has evolved by gathering information on patients’ perspectives and interactions with PN programs across Alberta. Our objectives were to (i) explore patients’ current experiences with PN programs, and (ii) identify the features of PN felt to be of particular value to patients. Methods: To address these objectives, we conducted an interpretive descriptive study to collate the experiences of adult patients with longitudinal exposure to Albertan PN programs (involvement for greater than or equal to one month). Participant recruitment occurred via key informant sampling with navigators across Alberta. One-on-one semi-structured interviews were conducted to explore patient experiences with PN and their understanding of it as a broader concept. Inductive thematic analysis and interpretive exercises were subsequently performed to construct a coherent message from the data. Continued collaboration with two patient partners was maintained throughout the study to ensure responsiveness to patient priorities. Results: This study involved 23 participants with experience using nurse navigators, transition navigators, and lay community health navigators. Irrespective of navigation type, the participants’ stories were tethered by their navigators’ promotion of seamless and personalized care, as well as their ability to seemingly humanize the healthcare system. This was accomplished through a set of participant-identified navigator characteristics, including approachability, accessibility, and comprehensive systems knowledge. While the identified functions and characteristics of navigators were consistent across participants, how these components were operationalized varied based on the program’s setting and the particular needs of each patient. Conclusion: As a patient-centred intervention, understanding patients’ experiences and valuations of PN is critical to distilling the essence of the intervention. This research directly addresses ongoing knowledge gaps surrounding contemporary understandings of PN, particularly from patients’ perspectives.

description: We study the variation of elliptic flow of thermal dileptons with transverse momentum and invariant mass of the pairs for Pb+Pb collisions at $\sqrt{s_{NN}}$ = 2.76 TeV. The dilepton productions from quark gluon plasma (QGP) and hot hadrons have been considered including the spectral change of light vector mesons in the thermal bath. The space time evolution has been carried out within the frame work of 2+1 dimensional ideal hydrodynamics with lattice+hadron resonance gas equation of state. We find that a judicious selection of invariant mass(M) and transverse momentum (p_T) windows can be used to extract the collective properties of quark matter, hadronic matter and also get a distinct signature of medium effects on vector mesons. Our results indicate a reduction of elliptic flow (v_2) for M beyond phi mass, which if observed experimentally would give the measure of v_2 of the partonic phase.

description: This article defines the Garmsiri Language Group. It is a continuum of closely related dialects extending from the Halilrud river valley in the north down to the Strait of Hormuz in the south. It incorporates Jirofti, Kahnuji, Rudbāri, Manujāni, Minābi, Bandari, and Baškardi. Some of the dialects investigated here as Garmsiri had long been known as (outer) Baškardi, a designation Ilya Gershevitch gave to the vernaculars outside of Baškard proper (which he divided into North and South Baškardi). Since the same term, Garmsiri, has been in use for the related dialects spoken in Lārestān of Fārs, it would be possible to designate the entire band of the dialects stretching along an upward-facing crescent from Lārestān to Halilrud as the Garmsiri languages of Kerman and Fārs, in lieu of the verbose terminology used to this date.
Identification, control and optimization strategies for thermo-mechanical pulping (TMP) processes

description: The focus of this thesis is to develop an advanced control system for existing and to-be developed Thermo-Mechanical Pulping (TMP) refining processes. Therefore, the thesis has two parts. The first part developed two different but yet complementary closed-loop identification methods to update the models used in the low-level control layer of the current advanced control systems for TMP refiners. These newly developed identification methods are specific to closed-loop systems controlled by Model Predictive Control (MPC) techniques, and successfully tailored to the presence of the MPC. By updating the existing process models, the current advanced control systems can be operated to give better performance. However, these control systems may not be able to provide optimal performance due to process disturbances. Hence, a novel economically oriented advanced control system is developed for the existing two-stage TMP refiner processes for their optimal operation when disturbances are present. This novel technique dynamically optimizes the TMP processes as opposed to conventional two-layer methods which perform process optimization at steady-state, and has shown a potential economical benefit through reduction of total specific energy of a two-stage TMP process in a simulation study. In the second part, a novel TMP process with multi-stages of Low Consistency (LC) refining is studied for its optimal operation. The proposed Nonlinear Model Predictive Control (NMPC) technique dynamically optimizes the process and provides better performance when disturbances are present. This economically oriented NMPC (econNMPC) minimizes the total specific energy consumption of the process while respecting all the process constraints and achieving final desired pulp quality. In simulation studies, a TMP process with multiple stages of LC refining was able to save significant specific energy consumption with setpoint tracking control when disturbances are present. Moreover, further reduction of specific energy has been achieved with the developed econNMPC technique.

description: We present a model-independent technique for calculating the time of mid-transits. This technique, named "barycenter method", uses the light-curve's symmetry to determine the transit timing by calculating the transit light-curve barycenter. Unlike the other methods of calculating mid-transit timing, this technique does not depend on the parameters of the system and central star. We demonstrate the capabilities of the barycenter method by applying this technique to some known transiting systems including several \emph{Kepler} confirmed planets. Results indicate that for complete and symmetric transit lightcurves, the barycenter method achieves the same precision as other techniques, but with fewer assumptions and much faster. Among the transiting systems studied with the barycenter method, we focus in particular on LHS 6343C, a brown dwarf that transits a member of an M+M binary system, LHS 6343AB. We present the results of our analysis, which can be used to set an upper limit on the period and mass of a possible second small perturber.
