Corso di lingua cantonese
No full textLa lingua cantonese è parlata principalmente nella regione cinese del Guangdong oltre che a Hong Kong, Macao e Singapore, nonché da milioni di cinesi della diaspora. Ha un lessico e una sintassi che ben si distinguono dal cinese mandarino, e un sistema di scrittura standardizzato e sempre più utilizzato nei quotidiani, nelle riviste, nei fumetti, nella cartellonistica e anche in letteratura, oltre che nelle trasmissioni radio e tv.
Questo testo è un corso di base per italiani interessati ad apprendere principalmente la lingua parlata e privilegia un approccio comunicativo, dando risalto alle funzioni linguistiche necessarie per condurre una conversazione di base su temi di vita quotidiana.
Il testo è arricchito da un CD-Mp3 che contiene le registrazioni dei dialoghi di tutte le unità e le tracce per svolgere gli esercizi di fonetica.
Il manuale si rivolge a coloro che per motivi di studio o lavoro abbiano necessità di acquisire una conoscenza di base della lingua, ma anche a coloro che già conoscono il cinese mandarino e vogliano cimentarsi da autodidatti nello studio del cantonese

A margin scheme that advises on when to change required margin
No full textThe purpose of a margin requirement is to protect a clearinghouse from members' defaults resulting from big losses due to adverse movement of futures prices. To decide on how much a margin is required, a clearinghouse may refer to a benchmark margin defined as a constant multiple of the forecasted volatility. However, a benchmark margin only advises on a desirable margin level. It gives no advice on whether a clearinghouse should alter existing required margin. This paper proposes a margin scheme that can advise on when to change the required margin and if a change is recommended, to what level it should be changed. The proposed margin scheme can be devised so that the coverage probability and change frequency are controlled at target levels deemed appropriate by the clearinghouse. The proposed margin scheme needs a volatility forecast as input. This paper shows that among a large number of volatility forecasts, implied volatility gives the best results. This confirms a conjecture that implied volatility may have more information content than other volatility forecasts as far as margin setting is concerned. © 2010 Elsevier B.V.

Why Do We Need to Coordinate When Classifying Kin?
No full textWe suggest that there are two coordination games when it comes to understanding kin terminology. Jones’ article focuses on the linguistic coordination inherent in developing meaningful kin terminologies, alluding briefly to the benefits of these kin terminologies for coordination in other domains. We enhance Jones’ discussion by tracing the links between the structure of kin terminologies and their functions.Open peer commentary on: Jones, Doug.

Computational studies of membrane proteins: Structure, function and dynamics
No full textIon channels are membrane proteins that regulate the flow of ions across the cell membrane. These channels open in response to changes in electrostatic potential across the cell membrane or binding of small molecules to the channels and allow the passage of specific ions through their conduction pore. In particular, K+, Na+, and Cl− channels play important roles in the generation of electrical signals, known as action potentials, which propagate through the membrane of excitable cells. Despite decades of study on the function of these ion channels, detailed molecular mechanisms of the gating and ion selectivity remain elusive.
The main aim of this dissertation is to employ molecular dynamics simulations to investigate the structure and function of ion channels, including the gating mechanism in voltage-gated potassium and sodium channels, as well as the ion selectivity in chloride channels. First, the mechanical coupling within the voltage-sensing S4 helix in potassium channels is studied using steered molecular dynamics and network analysis. The hydrogen bonds near the α- to 310-helix transition region in the S4 helix are of vital importance to force translation during voltage gating.
Next, anion selectivity in chloride channels is investigated by extensive free energy calculations on the single- and double-ion permeation through the conducting pore. The free energy profiles for Cl−, Br−, and NO3− ions suggest that the interactions between the ions and backbone amides near the ion-binding sites determine the selectivity. Permeation of Br− and NO3− ions are energetically penalized by disrupting the hydration of backbone amides due to their bigger size. The simulated double-ion permeation process has revealed that the comparable size of Cl− and water molecule facilitates a knock-on passage mechanism, which discriminates Cl− from other bulkier anions.
The third study concerns the molecular modeling of the structure of a sodium channel. Guided by cross-linking experiment data, a homology model of a eukaryotic sodium channel was constructed in the inactivated state, which has not been resolved in any previous studies. Free energy calculations on the inactivation process have identified a novel pore-blocking mechanism by the domain III S6 helix of domain III of the channel. Apart from molecular simulation, mathematical modeling of the gating kinetics for both the potassium and sodium channels establishes the functional linkage from the channels’ precise gating kinetics to the initiation of action potentials in neurons.
In addition, this dissertation presents two side projects. The first side project concerns the effects of Cy3 and Cy5 fluorophores on membrane protein dynamics. An extensive collection of simulations on various membrane proteins provides a detailed quantitative description of the fluorophore-lipid interactions and infer the perturbation on the structure and dynamics of the labeled proteins. The second side project describes a method utilizing an artificial neural network in performing dimensionality reduction for analysis of molecular dynamics simulations. In this dissertation, a collection of computational methods have been applied to study membrane proteins and ion channels and to provide molecular insights to explain experimental observations in these systems.Submission published under a 24 month embargo labeled 'U of I Access', the embargo will last until 2022-05-01The student, Kin Lam, accepted the attached license on 2020-05-01 at 19:38.The student, Kin Lam, submitted this Dissertation for approval on 2020-05-01 at 20:07.This Dissertation was approved for publication on 2020-05-05 at 16:29.DSpace SAF Submission Ingestion Package generated from Vireo submission #15165 on 2020-08-25 at 17:28:37Made available in DSpace on 2020-08-26T23:58:34Z (GMT).

Growth and Reproduction Characteristics of Plant's Kin Recognition in Two Different Lifestyle Species
No full textSome plant species grow with closely genetically related individuals, and may benefit from an ability to recognize kin and show cooperative behavior towards neighbors. Kin recognition has been demonstrated in few plant species till now and thus constrained the understanding of significance of kin recognition. We investigated different growth and reproduction characteristics of kin recognition in two lifestyle species, the annual plant Lolium multiflorum Lam. and the perennial plant Elymus sibiricus Linn., which the main differences between are in their root system types and nutrition demand. We observed less root biomass distribution in kin groups than stranger groups for L. multiflorum Lam., but no indication in shoot characteristics at either the individual level or group level. For E. sibiricus, there were no significant differences in any measured characteristic index between kin and stranger groups at any level. Our results suggest that kin selection or plant responses to kin may depend on plant features and life-form; the most sensitive traits to competition are more likely to respond to kin selection. In addition, we considered that kin selection was tensely associated with degree of competition. It could be that the moderate competition level in our experiment could not stimulate kin cooperation activity of E. sibiricus c 2018 Friends Science Publisher
