Responding to Indo-Pacific rivalry: Australia, India and middle power coalitions
No full textIn this Analysis, Lowy Institute International Security Program Director Rory Medcalf and Nonresident Fellow C. Raja Mohan argue that Chinese assertiveness and uncertainties about America’s role in Indo-Pacific Asia are causing middle powers to look for alternative approaches to regional security. The Analysis argues that enhanced security cooperation between Indo-Pacific middle powers should be extended to the creation of “middle-power coalitions” in the region.
Key findings
China’s assertiveness and uncertainties about America’s response are causing middle powers in Indo-Pacific Asia to looking beyond traditional approaches to security
Cooperation between Indo-Pacific middle power coalitions would build regional resilience against the vagaries of US-China relations
India and Australia are well placed to form the core of middle power coalition buildin
Emerging contours of financial regulation: challenges and dynamics.
No full textThe current ongoing financial crisis is attributed to a variety of factors such as the developments in the subprime mortgage sector, excessive leverage, lax financial regulation and supervision, and global macroeconomic imbalances. At a fundamental level, however, the crisis also reflects the effects of long periods of excessively loose monetary policy in the major advanced economies during the early part of this decade. The theory and belief of efficient and rational markets have been severely discredited by the current crisis. There is, therefore, a growing agreement for much strengthened, and perhaps, intrusive regulation and supervision in the financial sector. Hitherto unregulated institutions, markets and instruments will now have to be brought under the regulatory framework. A more developed macroprudential approach will be important. Once the current financial crisis is beyond us, minimum regulatory capital requirements would need to be signifi cantly above existing Basel rules, with emphasis on Tier I capital, and supported by a maximum gross leverage ratio. Liquidity regulation and supervision must be recognised as of equal importance to capital regulation, reinforced by an effective global liquidity framework for managing liquidity in large, cross-border fi nancial institutions. The issue of remuneration in the fi nancial sector would require reforms on an industry-wide basis so that improved risk management and compensation practices by some systemically important firms are not undermined by the unsound practices of others. Whereas the suggested reform principles are being increasingly well accepted, many challenges will arise on their modes of implementation, and their practicality. For instance, once normalcy returns, the fi nancial industry will do its utmost to resist the requirements for higher capital at that time. From the point of view of emerging market economies (EMEs), the volatility in capital flows – mainly the outcome of extant monetary policy regimes in developed countries – has led to severe problems in both macro management and financial regulation. This will remain a challenge since there is little international discussion on this issue. Finally, as the global economy starts recovery, a calibrated exit from the prevalent unprecedented accommodative monetary policy will have to be ensured to avoid the recurrence of the financial crisis being experienced now.

NANOMETRSKE CELULOZNE PLASTI ZA SPECIFIČNO ADSORPCIJO POLISAHARIDOV IN IMOBILIZACIJO BIOAKTIVNIH MOLEKUL
No full textThe aim of the thesis is to investigate the applicability of nanometric amorphous cellulose model films for the immobilization of functional DNA molecules and to apply this knowledge in the field of DNA microarray preparation. To achieve this aim, the whole thesis work is divided into three major parts, namely part I (partly and fully regenerated cellulose film preparation and its characterization), part II (functional polysaccharide conjugates preparation) and part III (DNA microarray preparation from polysaccharide functional conjugates).
The first part of the work mainly focuses on the preparation of cellulose model films from spin coated trimethylsilyl cellulose (TMSC) using an in-situ and ex-situ regeneration methods and its characterization. In the in-situ method, the conversion of TMSC to pure cellulose via acid vapor hydrolysis is investigated at the gas-solid interface in real time and at ambient conditions employing quartz crystal microbalance with dissipation (QCM-D). For this purpose, a permanent flow of gaseous HCl is employed which reacts with TMSC coated surface to form pure cellulose. The kinetics behind this reaction is elucidated and reveals first order. Moreover, the influence of the acid concentration on the kinetics and on changes in mass and film thickness of TMSC is studied.
In the case of an ex-situ method, partly and fully regenerated cellulose model films are prepared from spin coated TMSC films through acid vapor phase hydrolysis. This is done by exposing the TMSC films placed in a closed container to vapors of HCl. The regeneration is carried out on one hand by exposing the films to different time intervals and on the other hand to different volume of HCl. The changes in surface morphology, structure, surface composition and film thickness in the course of regeneration (i.e. desilylation) is studied by using various surface analytical techniques like atomic force microscopy (AFM), attenuated total reflectance infrared spectroscopy, X-ray photoelectron spectroscopy (XPS) and ‘Sarfus’-technique. In order to gain detailed insight into the desilylation reaction of the films the results from ATR-IR, XPS and thickness measurements are compared with data from static contact angle (SCA) and surface free energy (SFE) determination.
Besides, to verify the completion of regeneration of cellulose from TMSC the partly and fully regenerated films prepared using ex-situ method are interacted with cellulase enzymes from Trichoderma viride using QCM-D technique. The changes in mass and energy dissipation due to the interaction of the enzymes with the substrates are correlated with the surface wettability and elemental composition of the regenerated films. The enzymatic degradation rate correlated well to the rate of regeneration. It is demonstrated that capillary zone electrophoresis (CZE) can be used to support QCM-D data via the detection of enzyme hydrolysis products in the eluates of the QCM-D cells. It is also shown that a combination of QCM-D together with enzymatic digestion is a reliable method to monitor the time dependent regeneration of TMSC to pure cellulose.
Furthermore, the effect of heat treatment on partly and fully regenerated cellulose films prepared using ex-situ method is investigated by exposing the films to elevated temperature (105 °C) for a prolonged time (6 hours). Upon heating, a structural rearrangement in the films from a featureless to a fibrillar-like structure is observed as evidenced by AFM. Several analytical methods, namely GIXRD, ATR-IR, Sarfus, XPS and SCA data are employed to analyze the alteration in the structure, surface composition, film thickness, wettability and SFE of the time dependent regenerated films before and after heat treatment. Results from solvent (D2O/H2O) exchange studies proved that water content and water uptake capacity of heat treated cellulose films are significantly reduced compared to non heated films.Additionally, a new method is developed to structure nanometric cellulose films via vapor phase acid hydrolysis and enzymatNamen predstavljenega doktorskega dela je razvoj nanometrskih amorfnih celuloznih modelnih filmov za imobilizacijo funkcionalnih DNA molekul in uporaba pridobljenega znanja za pripravo DNA mikromrež. Doktorska disertacija je razdeljena v tri dele in sicerpriprava in karakterizacija delno in popolnoma regeneriranih celuloznih filmovpriprava funkcionalnih polisaharidnih konjugatov in priprava DNA mikromrež s polisaharidnimi funkcionalnimi konjugati.
Prvi del se nanasa predvsem na in-situ in ex-situ regeneracijo celuloznih filmov in njihovo karakterizacijo. Z uporabo kremenove mikrotehtnice (QCM-D metoda) smo podrobno spremljali hidrolizo in konverzijo trimetilsililne celuloze (TMSC) v celulozo v hlapih klorovodikove kisline. Plinasta HCl v neprekinjenem dotoku reagira s plastjo TMSC in na taksen nacin tvori plast celuloze. Raziskali smo kinetiko procesa regeneracije in dolocili reakcijo prvega reda. Poleg tega smo raziskali tudi vpliv koncentracije kisline na kinetiko reakcije ter na maso in debelino formiranega sloja celuloze.
Za potrebe študija ex-situ regeneracije smo prav tako pripravili TMSC filme s tehniko \u27\u27spin coat\u27\u27. V nasprotju z in-situ metodo regeneracije smo v tem primeru položili substrate s TMSC filmi v zaprto posodo, kjer so bili izpostavljeni hlapom klorovodikove kisline. Postopek regeneracije je potekal pri različnih časih izpostavitve kislinskim hlapom ter volumnih kisline. Spremembe v strukturi, debelini filmov, površinski elementni sestavi ter površinski prosti energiji regeneriranih celuloznih filmov (pri različnih časih regeneracije) smo raziskali z uporabo, ATR-IR, Sarfus, XPS tehnik ter z merjenjem stičnih kotov.
Z interakcijo med delno ter popolnoma regeneriranimi celuloznimi filmi in encimom celulazo (Trichoderma viride) smo dodatno raziskali stopnjo hidrolize TMSC filmov in posledično stopnjo njihove regeneracije. Spremembe v masi filma in disipaciji energije, kot posledice delovanja celulaze, smo korelirali s sposobnostjo omakanja filmov in njihovo elementno sestavo. Stopnja encimske razgradnje regeneriranih celuloznih filmov je v dobri korelaciji s stopnjo regeneracije. V kombinaciji s kvarčno mikrotehtnico smo uporabili tudi kapilarno consko elektroforezo, s katero smo določili razgradne produkte encimske hidrolize celuloznih filmov. Kombinacija QCM-D tehnike in postopek encimske razgradnje celuloznih filmov se je izkazala koz zanesljiva metoda spremljanja regeneracije TMSC filmov v odvisnosti od časa.
Vpliv toplotne obdelave na tako pripravljene filme smo dolocili z naknadno izpostavitvijo celuloznih filmov povišani temperaturi za daljši čas (6 ur). Segrevanje povzroci preureditev filmov, ki se ne ponašajo s posebnimi strukturnimi artefakti, v fibrilarno strukturo, kar je razvidno iz AFM posnetkov. Uporabili smo različne analitske metode, s katerimi smo raziskali spremembe v strukturi, elementni sestavi, debelini, sposobnosti omakanja ter prosti površinski energiji regeneriranih celuloznih filmov pred in po toplotni obdelaviGIXRD, ATR-IR, Sarfus tehnika, XPS in goniometrija. Z izvedbo postopka izmenjave topila (D2O/H2O) smo dokazali, da se vsebnost vode in sposobnost navzemanja vode toplotno obdelanih regeneriranih celuloznih filmov občutno zmanjša v primerjavi z neobdelanimi filmi..
Mohan Siṅgh : une poétique de l’ambivalence
No full textInternational audienceMohan Siṅgh (1905-1978), que nous avons croisé comme nouvelliste au chapitre V, recueillit l’héritage des grands poètes des années 1920-1930 rencontrés aux chapitres II et IV, et il le transcenda, créant un idiome poétique divers, résolument moderne et ouvert à toute l’expérience humaine dès les trois recueils qu’il publia avant 1947 : Sāve pattar « Feuilles vertes » (1936), Kasumbhaṛā « Carthame » (1939) et Adhvāṭe « À mi-chemin » (1944). Avec Mohan Singh apparaît une poésie en panjabi d’auteur sikh dans laquelle le sikhisme est présent seulement comme l’une des composantes de la vie panjabie : le lien est désormais radicalement défait entre écriture poétique et apologétique. Le grand thème de Mohan Siṅgh est l’amour, et pour le chanter sa poésie s’empare en un harmonieux chant du monde de tout ce qui fait la réalité du Panjab, des paysages aux activités de la vie rurale et aux rapports sociaux. Sur le plan politique, Mohan Siṅgh a fait le choix du socialisme, comme nombre des écrivains de son temps, au premier rang desquels, parmi les sikhs, Sant Siṅgh Sekhoṃ. Mais il faudra longtemps pour que l’amour et l’espérance deviennent deux dimensions indissociables de son écriture. Lorsque paraît Adhvāṭe en 1943, l’horizon socialiste est encore, nous l’avons vu, subordonné dans la poésie de Mohan Siṅgh à l’expérience amoureuse : son narrateur n’en fait pas un choix actif, un combat ; le monde tel qu’il est lui convient, puisqu’il parvient, par l’amour, à y connaître le bonheur

The metabolic syndrome in developing countries
No full textThe occurrence of the metabolic syndrome in various ethnic groups - including Caucasians, Africans, Latin Americans, Asian Indians, Chinese, Aboriginal Australians, Polynesians and Micronesians - has been confirmed in several epidemiological studies. In developing countries, the lifestyle changes resulting from industrialization and rural-urban migration involve decreased levels of physical activity and the increased intake of energy. As reported by Viswanathan Mohan and Mohan Deepa in this article, the consequent rise in rates of obesity has led to a huge increase in the numbers of people with the metabolic syndrome in developing regions

Towards reasoning and coordinating action in the mental space
No full textUnlike a purely reactive system where the motor output is exclusively controlled by the actual sensory
input, a cognitive system must be capable of running mental processes which virtually simulate action
sequences aimed at achieving a goal. The mental process either attempts to find a feasible course of
action compatible with a number of constraints (Internal, Environmental, Task Specific etc) or selects
it from a repertoire of previously learned actions, according to the parameters of the task. If neither
reasoning process succeeds, a typical backup strategy is to look for a tool that might allow the operator
to match all the task constraints. This further necessitates having the capability to alter ones own
goal structures to generate sub-goals which must be successfully accomplished in order to achieve the
primary goal. In this paper, we introduce a forward/inverse motor control architecture (FMC/ IMC)
that relaxes an internal model of the overall kinematic chain to a virtual force field applied to the end
effector, in the intended direction of movement. This is analogous to the mechanism of coordinating the
motion of a wooden marionette by means of attached strings. The relaxation of the FMC/IMC pair
provides a general solution for mentally simulating an action of reaching a target position taking into
consideration a range of geometric constraints (range of motion in the joint space, internal and external
constraints in the workspace) as well as effort-related constraints (range of torque of the actuators, etc.).
In case, the forward simulation is successful, the movement is executed; otherwise the residual “error”
or measure of inconsistency is taken as a starting point for breaking the action plan into a sequence
of sub actions. This process is achieved using a recurrent neural network (RNN) which coordinates
the overall reasoning process of framing and issuing goals to the forward inverse models, searching for
alternatives tools in solution space and formation of sub-goals based on past context knowledge and present inputs. The RNN+FMC/IMC system is able to successfully reason and coordinate a diverse range of reaching and grasping sequences with/without tools. Using a simple robotic platform (5 DOF Scorbot arm+Stereo vision) we present results of reasoning and coordination of arm/tool movements (real and mental simulation) specifically directed towards solving the classical 2-stick paradigm from animal reasoning at a non linguistic level
