description: In this work we discuss the secondary market for life insurance policies in the United States of America. First, we give an overview of the life settlement market: how it came into existence, its growth prospects and the ethical issues it arises. Secondly, we discuss the characteristics of the 	different life insurance products present in the market and describe how life settlements are originated. Life settlement transactions tend to be long and complex transactions that require the involvement of a number of parties. Also, a direct investment into life insurance policies is fraught with a number of practical issues and entails risks that are not directly related to longevity. This may reduce the efficiency of a direct investment in physical policies. For these reasons, a synthetic longevity market has evolved. The number of parties involved in a synthetic longevity transaction is typically smaller and the broker-dealer transferring the longevity exposure will be retaining most or all of the risks a physical investment entails. Finally, we describe the main methods used in the market to evaluate life settlement investments and the role of life expectancy providers.

description: The electronic and magnetic properties of cobalt-based layered oxypnictides, LaCoOX (X = P, As), are investigated. LaCoOP and LaCoOAs show metallic type conduction, and the Fermi edge is observed by hard x-ray photoelectron spectroscopy. Ferromagnetic transitions occur at 43 K for LaCoOP and 66 K for LaCoOAs. Above the transition temperatures, temperature dependence of the magnetic susceptibility follows the Curie-Weiss law. X-ray magnetic circular dichroism (XMCD) is observed at the Co L2,3-edge, but not at the other edges. The calculated electronic structure shows a spin polarized ground state. These results indicate that LaCoOX are itinerant ferromagnets and suggest that their magnetic properties are governed by spin fluctuation.

description: This work shows for the first time that native CSTB polymerizes on addition of Cu2+ and DnaK (Hsp70). Cysteines are involved in the polymerization process and in particular at least one cysteine is necessary. We propose that Cu2+ interacts with the thiol group of cysteine and oxidize it. The oxidized cysteine modifies the CSTB structure allowing interaction with DnaK/Hsp70 to occur. Thus, Cu2+ binding to CSTB exposes a site for DnaK and such interaction allows the polymerization of CSTB. The polymers generated from native CSTB monomers, are DTT sensitive and they may represent physiological polymers. Denatured CSTB does not require Cu2+  and polymerizes simply on addition of DnaK. The polymers generated from denatured CSTB do not respond to DTT. They have characteristics similar to those of the CSTB toxic aggregates described in vivo in eukaryotic cells following CSTB over-expression. 
Interaction between CSTB and Hsp70 is shown by IP experiments. The interaction occurs with WT CSTB and not with the ïcys mutant. This suggests that disulphur bonds are involved. 
Methal-cathalyzed oxidation of proteins involves reduction of the metal ion(s) bound to the protein itself and oxidation of neighboring ammino acid residues resulting in structural modification and de-stabilization of the molecule. In this work we propose that the cysteine thyol residue of CSTB in the presence of Cu2+ is oxidized, and cathalyzes the formation of  disulphide bonds with Hsp70, that, once bound to CSTB, mediates its polymerization. In vivo this molecular mechanism of CSTB polymerization could be regulated by redox environment through the cysteine residue. This may imply that CSTB physiological polymers have a specific cellular function, different from that of the protease inhibitor known for the CSTB monomer.
This hypothesis is interesting in relation to Progressive Myoclonus Epilepsy of type 1 (EPM1). This pathology is usually caused by mutations in the CSTB gene. CSTB is a ubiquitous protein, but EPM1 patients have problems only in the central nervous system. Maybe physiological CSTB polymers have a specific function altered in people affected by EPM1.
Expressiveness in biologically inspired languages

description: A very recent and exciting new area of research is the application of Concurrency Theory tools to formalize and analyze biological systems and one of the most promising approach comes from  the  process algebras (process calculi).
A process calculus is a formal language that allows to describe concurrent systems and comes with well-established techniques for quantitative and qualitative analysis.   
Biological systems can be regarded as concurrent systems    and therefore modeled by means of process calculi.
In this thesis we focus on the process calculi approach to the modeling of biological systems and investigate, mostly from a theoretical point of view, several promising bio-inspired formalisms: Brane Calculi and k-calculus family.
We provide several expressiveness results mostly by means of comparisons between calculi.
We provide a lower bound to the computational power of the non Turing complete MDB Brane Calculi by showing an encoding of a simple P-System into MDB.
We address the issue of local implementation within the  k-calculus family: whether  n-way rewrites can be simulated by binary interactions only. A solution introducing divergence is provided and we prove a deterministic solution preserving the termination property is not possible.
We use the symmetric leader election problem to test synchronization capabilities within the k-calculus family. Several fragments of the original  k-calculus are considered and we prove an impossibility result about encoding n-way synchronization into (n-1)-way synchronization.
A similar impossibility result is obtained in a pure computer science context. We introduce CCSn, an extension of CCS with multiple input prefixes and show, using the dining philosophers problem, that there is no reasonable encoding of CCS(n+1) into CCSn.
Essays on European economic and monetary integration

description: This thesis focuses on two aspects of European economic integration: exchange rate stabilization between non-euro Countries and the Euro Area, and real and nominal convergence of Central and Eastern European Countries. Each Chapter covers these aspects from both a theoretical and empirical perspective. Chapter 1 investigates whether the introduction of the euro was accompanied by a shift in the de facto exchange rate policy of European countries outside the euro area, using methods recently developed by the literature to detect "Fear of Floating" episodes. I find that European Inflation Targeters have tried to stabilize the euro exchange rate, after its introduction; fixed exchange rate arrangements, instead, apart from official policy changes, remained stable. Finally, the euro seems to have gained a relevant role as a reference currency even outside Europe. Chapter 2 proposes an approach to estimate Central Bank preferences starting from the Central Bank's optimization problem within a small open economy, using Sweden as a case study, to find whether stabilization of the exchange rate played a role in the Monetary Policy rule of the Riksbank. The results show that it did not influence interest rate setting; exchange rate stabilization probably occurred as a result of increased economic integration and business cycle convergence.
Chapter 3 studies the interactions between wages in the public sector, the traded private sector and the closed sector in ten EU Transition Countries. The theoretical literature on wage spillovers suggests that the traded sector should be the leader in wage setting, with non-traded sectors wages adjusting. We show that large heterogeneity across countries is present, and sheltered and public sector wages are often leaders in wage determination. This result is relevant from a policy perspective since wage spillovers, leading to costs growing faster than productivity, may affect the international cost competitiveness of the traded sector.

description: The fundamental task of group testing is to recover a small distinguished subset of items from a large population while efficiently reducing the total number of tests (measurements). The key contribution of this paper is in adopting a new information-theoretic perspective on group testing problems. We formulate the group testing problem as a channel coding/decoding problem and derive a single-letter characterization for the total number of tests used to identify the defective set. Although the focus of this paper is primarily on group testing, our main result is generally applicable to other compressive sensing models. The single letter characterization is shown to be order-wise tight for many interesting noisy group testing scenarios. Specifically, we consider an additive Bernoulli($q$) noise model where we show that, for $N$ items and $K$ defectives, the number of tests $T$ is $O(\frac{K\log N}{1-q})$ for arbitrarily small average error probability and $O(\frac{K^2\log N}{1-q})$ for a worst case error criterion. We also consider dilution effects whereby a defective item in a positive pool might get diluted with probability $u$ and potentially missed. In this case, it is shown that $T$ is $O(\frac{K\log N}{(1-u)^2})$ and $O(\frac{K^2\log N}{(1-u)^2})$ for the average and the worst case error criteria, respectively. Furthermore, our bounds allow us to verify existing known bounds for noiseless group testing including the deterministic noise-free case and approximate reconstruction with bounded distortion. Our proof of achievability is based on random coding and the analysis of a Maximum Likelihood Detector, and our information theoretic lower bound is based on Fano's inequality.

description: For molecules and materials responding to femtosecond-scale optical laser pulses, we predict maximum relative excitation of a Raman-active vibrational mode with period T when the pulse has an FWHM duration of 0.42 T. This result follows from a general analytical model, and is precisely confirmed by detailed density-functional-based dynamical simulations for C60 and a carbon nanotube, which include anharmonicity, nonlinearity, no assumptions about the polarizability tensor, and no averaging over rapid oscillations within the pulse. The mode specificity is, of course, best at low temperature and for pulses that are electronically off-resonance, and the energy deposited in any mode is proportional to the fourth power of the electric field.

description: The radial-orbit instability is a collective phenomenon that has heretofore only been observed in spherical systems. We find that this instability occurs also in triaxial systems, as we checked by performing extensive N-body simulations whose initial conditions were obtained by sampling a self-consistent triaxial model of a cuspy galaxy composed of luminous and dark matter. N-body simulations show a time evolution of the galaxy that is not due to the development of chaotic motions but, rather, to the collective instability induced by an excess of box-like orbits. The instability quickly transforms such models into a more prolate configuration, with 0.64

description: Enzyveba, a partially characterized complex consortium of not-adapted microorganisms developed through prolonged stabilization of organic wastes, was found to markedly intensify the aerobic remediation of aged PAH- and PCB-contaminated soil by acting as a source of exogenous specialized microorganisms and nutrients. Thus, Enzyveba was tested in the bioremediation of Diesel (G1) and HiQ Diesel (G2) contaminated soils under aerobic slurry-phase conditions by means of a chemical, microbiological, ecotoxicological integrated analytical procedure. The addition of Enzyveba resulted in a higher availability of cultivable specialized bacteria and fungi but this resulted in a slight intensification of soil remediation, probably because of the high content of nutrients and specialized microorganisms of the soil. In many cases, the biotreatability of soils impacted by diesel fuel is limited by their poor content of autochthonous pollutant-degrading microorganisms. Thus, bioaugmentation with stable and reproducible cultures with the required broad substrate specificity might be the solution for a successful remediation. Two microbial consortia, ENZ-G1 and ENZ-G2, were enriched from Enzyveba on G1 and G2. Both consortia consist of a similar composition of bacterial and fungal species. They exhibited a comparable and significant biodegradation capability by removing about 90% of 1 g/l of diesel fuel under liquid culture conditions. Given their remarkable biodegradation potential, richness of quite diverse microbes, stability and resistance after cryopreservation at -20 °C for several months, both consortia appear very interesting candidates for bioaugmentation on site. The mycoflora of a soil historically contaminated by high concentration of PCBs was characterised before, at the beginning and at the end of the biotreatment mentioned above. Several mitosporic fungi isolated from soil grew in presence of a mixture of three PCBs congeners when also glucose was provided. This is the first study in which 5 strains of mitosporic species able to biodegrade PCB are reported in the literature.

description: The present dissertation collects the results of three different research trials which have the common aim to understand the effects of swine welfare (both at farm level and during transport) on the main fresh and dry-cured meat characteristics. 
The first trial was carried out in order to compare the effects of illumination regimes differing in light duration or light intensity on meat and ham quality of Italian heavy pigs. The results of this trial support the conclusion that, within a moderate range of light intensity and given an appropriate dark period for animal rest, an increase of light duration or intensity above the minimum mandatory levels has no negative impact on carcass composition, meat or long-cured hams quality.
The second trial was designed with the aim to investigate the effects of water restriction on growth traits, animal welfare and meat and ham quality of liquid-fed heavy pigs. Overall, the parameters analyzed as concerns growth rate, behavioural traits, blood, as well as carcass, fresh meat and cured hams quality were not affected by the absence of fresh drinking water. However, since liquid feeding did not suppress drinker use or drinker manipulation in the experimental groups, water restriction does not appear to be an applicable method to obtain a reduction of water waste.
The third trial, which was carried out in Canada, tested the effectiveness of water sprinkling market-weight pigs (115±10Kg BW) before and after transport in reducing the heat stress experienced under commercial transport conditions. Our results show that the water sprinkling protocol proposed may reduce heat stress during transport and improve pork quality, particularly in specific trailer compartments.
This body of research supports the general conclusion that swine welfare could be improved in different scenarios through simple and cost-effective means, without negatively affecting the quality of the main animal-derived products.

description: Данная работа является продолжением исследований авторов в области проектирования систем автоматического фенотипирования растений. Интенсивное развитие цифровых технологий в агробизнесе позволяет снизить количество ошибок при визуальном анализе здоровья растений, повысить их урожайность и, как следствие, производительность труда специалистов. Построение автоматической системы фенотипирования требует анализа значительного объема цифровых изображений растений (более тысячи). Ключевым элементом автоматической системы фенотипирования является аппарат сверточных нейронных сетей, с помощью которого проводится анализ характеристик листьев растений во взаимосвязи с внешней средой, заболеваниями и морфологическими характеристиками. Анализ качества работы автоматической системы фенотипирования на базе сверточных нейронных сетей показал ее высокую эффективность при оценке заболеваний растений. В качестве компоненты адаптации системы управления в работе используется Е-сетевой граф, позволяющий формировать вектор управления системами технического зрения и выработки агрономических рекомендаций.
description: The article continues the study devoted to the design of automatic plant phenotyping systems. This topic of scientific research is now widely developed. The intensive development of digital technologies in agribusiness can significantly increase labor productivity, reduce errors in the visual analysis of plant health, and as a result, increase productivity. It is commonly known that building an automatic plant phenotyping system requires mass analysis of a large number (about a thousand) of plants through digital image processing. As a key element of the automatic phenotyping system, the convolutional neural network apparatus is used. This apparatus analyzes the characteristics of plant leaves under the influence of the external environment for the presence of diseases and morphological features of the plant. The analysis of the quality of the automatic phenotyping system based on convolutional neural networks shows a high efficiency of plant disease assessment. As a component of the adaptation of the control system, we use the E-network graph, which allows forming a control vector for the technical vision system and the development of agronomic recommendations.

description: Most electronic systems can be described in a very simplified way as an assemblage of analog and digital components put all together in order to perform a certain function. Nowadays, there is an increasing tendency to reduce the analog components, and to replace them by operations performed in the digital domain. This tendency has led to the emergence of new electronic systems that are more flexible, cheaper and robust. However, no matter the amount of digital process implemented, there will be always an analog part to be sorted out and thus, the step of converting digital signals into analog signals and vice versa cannot be avoided. This conversion can be more or less complex depending on the characteristics of the signals. Thus, even if it is desirable to replace functions carried out by analog components by digital processes, it is equally important to do so in a way that simplifies the conversion from digital to analog signals and vice versa.

In the present thesis, we have study strategies based on increasing the amount of processing in the digital domain in such a way that the implementation of analog hardware stages can be simplified. To this aim, we have proposed the use of very low quantized signals, i.e. 1-bit, for the acquisition and for the generation of particular classes of signals.

A methodology for derivation of marginal costs of hospital cases and application to estimation of cost savings from community health centres
Creators: name: Barer, Morris Lionel
Publisher: name: University of British Columbia
Year: 2010

description: Considerable attention has been devoted in the past to documenting the impact of prepaid group practices and community health centres on inpatient hospital utilization. The thesis develops and applies a methodology designed to allow estimation of the fiscal implications of such evidence. An equation relating average hospital inpatient costs to a number of explanatory variables is specified. The maximum likelihood estimation technique is employed in a time-series/cross-section analysis to determine parameter estimates for that equation over the period 1966-73. The variables are constructed from data deriving from eighty-seven British Columbia public general hospitals. Empirical results indicate the importance of case mix, average length of inpatient stay, rate of case flow and education-related hospital activities in explaining the variance across the eighty-seven hospitals in average cost per separation. The parameter estimates derived in the unit cost analysis are utilized in a comparative static determination of the implications for unit costs of changes in a hospital's case mix. The impact of case-specific case mix changes on unit (per separation) costs is determined, from which analysis case-specific marginal costs are derived. Finally, the marginal case costs are combined with utilization statistics from matched population studies involving community health centres or prepaid group practices. This allows determination of the expenditure implications of the utilization differentials reported in that literature. A subsequent extrapolative and conjectural analysis considers the cost implications of more widespread use of community health centres as a mode of medical care delivery in British Columbia. The conclusions suggest that the fiscal impact on the overall medical care budget in B.C. would be minimal in the absence of corresponding reductions in numbers of hospital beds. A number of other applications of the case cost derivation methodology are suggested.
Agrofood chain analysis: production, commercialisation and consumption of healthy food for population at risk of poverty in Italy

description: Italy registers a fast increase of low income population. Academics and policy makers consider income inequalities as a key determinant for low or inadequate healthy food consumption.
Thus the objective is to understand how to overcome the agrofood chain barriers towards healthy food production, commercialisation and consumption for population at risk of poverty (ROP) in Italy.
The study adopts a market oriented food chain approach, focusing the research ambit on ROP consumers, processing industries and retailers. 
The empirical investigation adopts a qualitative methodology with an explorative approach. The actors are investigated through 4 focus groups for consumers and carrying out 27 face to face semi-structured interviews for industries and retailers’ representatives. The results achieved provide the perceptions of each actor integrated into an overall chain approach.
The analysis shows that all agrofood actors lack of an adequate level of knowledge towards healthy food definition. Food industries and retailers also show poor awareness about ROP consumers’ segment. In addition they perceive that the high costs for producing healthy food conflict with the low economic performances expected from ROP consumers’ segment. These aspects induce a scarce interest in investing on commercialisation strategies for healthy food for ROP consumers. Further ROP consumers show other notable barriers to adopt healthy diets caused, among others, by a personal strong negative attitude and lack of motivation. The personal barriers are also negatively influenced by several external socio-economic factors. The solutions to overcome the barriers shall rely on the improvement of the agrofood chain internal relations to identify successful strategies for increasing interest on low cost healthy food. In particular the focus should be on improved collaboration on innovation adoption and marketing strategies, considering ROP consumers’ preferences and needs. An external political intervention is instead necessary to fill the knowledge and regulations’ gaps on healthy food issues.

description: We investigate the cubic to tetragonal phase transition in the pressure-temperature phase diagram of strontium titanate SrTiO3 (STO) by means of Raman spectroscopy and X-ray diffraction on single crystal samples. X-ray diffraction experiments are performed at room temperature, 381 and 467 K up to 53 GPa, 30 GPa and 26 GPa respectively. The observation of the superstructure reflections in the X-ray patterns provides evidence that the crystal undergoes at all investigated temperatures a pressure-induced transition from cubic to the tetragonal I4/mcm phase, identical to the low-temperature phase. No other phase transition is observed at room temperature up to 53 GPa. Together with previously published data, our results allow us to propose a new linear phase boundary in the pressure-temperature phase diagram. The data are analyzed in the framework of the Landau theory of phase transitions. With a revised value of the coupling coefficient between the order parameter and the volume spontaneous strain, the model built from pressure-independent coefficients reproduces satisfactorily the boundary in the phase diagram, but fails at reflecting the more pronounced second-order character of the pressure-induced phase transition as compared to the temperature-induced transition. We propose a new Landau potential suitable for the description of the pressure-induced phase transition. Finally, we show that particular attention has to be paid to hydrostatic conditions in the study of the high-pressure phase transition in STO.

description: We present a measurement of the differential cross section for $t\bar{t}$ events produced in $p\bar{p}$ collisions at $\sqrt{s}=1.96$ TeV as a function of the transverse momentum ($p_T$) of the top quark. The selected events contain a high-$p_T$ lepton ($\ell$), four or more jets, and a large imbalance in $p_T$, and correspond to 1 fb${}^{-1}$ of integrated luminosity recorded with the D0 detector. Each event must have at least one candidate for a $b$ jet. Objects in the event are associated through a constrained kinematic fit to the $t\bar{t}\to WbW\bar{b} \to \ellνb q\bar{q}'\bar{b}$ process. Results from next-to-leading-order perturbative QCD calculations agree with the measured differential cross section. Comparisons are also provided to predictions from Monte Carlo event generators using QCD calculations at different levels of precision.

description: Assuming that the positron excess in PAMELA satellite data is a consequence of annihilations of cold dark matter, we consider from a model-independent perspective if the data show a preference for the spin of dark matter. We then perform a general analysis of annihilations into two-body final states to determine what weighted combination of channels best describes the data.

description: Jets of high-redshift active galactic nuclei (AGNs) can be used to directly probe the activity of the black holes in the early Universe. Radio sources with jets misaligned with respect to the line of sight are expected to dominate the high-redshift AGN population. In this paper, we present the high-resolution imaging results of a z=4.57 AGN J2102+6015 by analyzing its multi-epoch dual-frequency very long baseline interferometry (VLBI) data. The 8.4-GHz VLBI images reveal two major features along the east-west direction separated by $\sim$ 10 milli-arcsec (mas). From the spectral index map, both features show flat/inverted spectra. The separation between the two features remains almost unchanged over an observation period of $\sim$ 13 years, placing an upper limit of the separation speed as about 0.04 mas year$^{-1}$. Previous studies have classified the source as a GHz-peaked spectrum quasar. Our results indicate that J2102+6015 is most likely a young, compact symmetric object rather than a blazar-type core-jet source.

Spin-glass instability of short-range spherical ferromagnet

description: In structurally disordered ferromagnets the weak random dipole-dipole exchange may transform the polydomain state into a spin-glass one. To some extent the properties of such phase in disordered isotropic ferromagnet can be qualitatively described by the spherical model with the short-range ferromagnetic interaction and weak frustrated infinite-range random-bond exchange. This model is shown to predict that spin-glass phase substitute the ferromagnetic one at the arbitrary small disorder strength and that its thermodynamics has some similarity to that of polydomain state along with some significant distinctions. In particular, the longitudinal susceptibility at small fields becomes frozen below transition point at a constant value depending on the disorder strength, while the third order nonlinear magnetic susceptibilitiy exhibits the temperature oscillations in small field near the transition point. The relation of these predictions to the experimental data for some disordered isotropic ferromagnets is discussed.

Model predictive control in thermal management of multiprocessor systems-on-chip

description: MultiProcessor Systems-on-Chip (MPSoC) are the core of nowadays and next
generation computing platforms. Their relevance in the global market continuously
increase, occupying an important role both in everydaylife products (e.g.
smartphones, tablets, laptops, cars) and in strategical market sectors as aviation,
defense, robotics, medicine. Despite of the incredible performance improvements
in the recent years processors manufacturers have had to deal with issues, commonly
called “Walls”, that have hindered the processors development. After the
famous “Power Wall”, that limited the maximum frequency of a single core and
marked the birth of the modern multiprocessors system-on-chip, the “Thermal
Wall” and the “Utilization Wall” are the actual key limiter for performance improvements.
The former concerns the damaging effects of the high temperature
on the chip caused by the large power densities dissipation, whereas the second
refers to the impossibility of fully exploiting the computing power of the processor
due to the limitations on power and temperature budgets. In this thesis we
faced these challenges by developing efficient and reliable solutions able to maximize
performance while limiting the maximum temperature below a fixed critical
threshold and saving energy. This has been possible by exploiting the Model Predictive
Controller (MPC) paradigm that solves an optimization problem subject
to constraints in order to find the optimal control decisions for the future interval.
A fully-distributedMPC-based thermal controller with a far lower complexity
respect to a centralized one has been developed. The control feasibility and interesting
properties for the simplification of the control design has been proved
by studying a partial differential equation thermal model. Finally, the controller
has been efficiently included in more complex control schemes able to minimize
energy consumption and deal with mixed-criticalities tasks

description: Context: Open clusters (OCs) are widely used as test particles to investigate a variety of astrophysical phenomena, from stellar evolution to Galactic evolution. Gaia and the complementary massive spectroscopic surveys are providing an unprecedented wealth of information about these systems. Aims: The Open Cluster Chemical Abundances from Spanish Observatories (OCCASO) survey aims to complement all this work by determining OCs accurate radial velocities and chemical abundances from high-resolution, R$\geq$60\,000, spectra. Methods: Radial velocities have been obtained by cross-correlating the observed spectra with a library of synthetic spectra which covers from early M to A spectral types. Results: We provide radial velocities for 336 stars, including several Gaia Benchmark Stars and objects belonging to 51 open clusters. The internal uncertainties of the derived radial velocities go from 10 m/s to 21 m/s as a function of the instrumental configuration used. The derived radial velocities, together with the Gaia proper motions, have been used to investigate the cluster membership of the observed stars. After this careful membership analysis, we obtain average velocities for 47 open clusters. To our knowledge, this is the first radial velocity determination for 5 of these clusters. Finally, the radial velocities, proper motions, distances and ages have been used to investigate the kinematics of the observed clusters and in the integration of their orbits.

Coupling/decoupling between translational and rotational dynamics in a supercooled molecular liquid

Year: 2008

description: We use molecular dynamics computer simulations to investigate the coupling/decoupling between translational and rotational dynamics in a glass-forming liquid of dumbbells. This is done via a careful analysis of the $α$-relaxation time $τ_{q^{*}}^{\rm C}$ of the incoherent center-of-mass density correlator at the structure factor peak, the $α$-relaxation time $τ_{2}$ of the reorientational correlator, and the translational ($D_{t}$) and rotational ($D_{r}$) diffusion constants. We find that the coupling between the relaxation times $τ_{q^{*}}^{\rm C}$ and $τ_{2}$ increases with decreasing temperature $T$, whereas the coupling decreases between the diffusivities $D_{t}$ and $D_{r}$. In addition, the $T$-dependence of $D_{t}$ decouples from that of $1/τ_{2}$, which is consistent with previous experiments and has been interpreted as a signature of the "translation-rotation decoupling." We trace back these apparently contradicting observations to the dynamical heterogeneities in the system. We show that the decreasing coupling in the diffusivities $D_{t}$ and $D_{r}$ is only apparent due to the inadequacy of the concept of the rotational diffusion constant for describing the reorientational dynamics in the supercooled state. We also argue that the coupling between $τ_{q^{*}}^{\rm C}$ and $τ_{2}$ and the decoupling between $D_{t}$ and $1/τ_{2}$, both of which strengthen upon cooling, can be consistently understood in terms of the growing dynamic length scale.
