description: Da una costante e giornaliera serie di più vaste composizioni, risultato della sua attuale ricerca scientifica, di indagine minuta, sulla qualità della informazione, trasformate criticamente
dall’autrice stessa, in più brevi capitoli, deriva la selezione attuale, che si materializza in questa sintesi, che proviene da ben più vasta ed analitica documentazione della sua investigazione letteraria.
I parametri introdotti, dimostrano l’impegno compositivo costante, nella delineazione di una nuova prospettiva di lettura, rivolta alla dimensione letteraria e comunicativa, sulla scena contemporanea italiana. Questa monografia promuove una sensibilità diversa da quella oggi dominante. Una autrice scientifica, pioniera in più aree di punta, da più di un trentennio, e che ha stabilizzato i risultati della propria ricerca, periodo per periodo, fase per fase, con accuratezza storica, si presenta questa volta, come scrittrice letteraria, e si dichiara attiva, negli studi della letteratura italiana, dal secondo decennio del XXI secolo.
L’autrice, narratrice e saggista, propone considerazioni precise, relative alla quotidianità, riflessioni, che smaterializza di ogni spessore polemico, attraverso una prosa soffusa di auto ironica saggezza, di evidente sostanza didattica. La prima parte del titolo, latineggiante, richiama la serietà dei temi trattati, seppur con quella retorica leggerezza, che sempre si basa sulla analisi rigorosa e scientifica dell’esistente. La scienziata distingue il panorama reale, lo stato di fatto delle letterature contemporanee scritte, o tradotte in lingua italiana, dalla loro rispettiva dimensione virtuale. Separa quindi, nettamente, la considerazione descrittiva, già ampiamente da molti praticata, da quella cui lei personalmente tiene di più, ovvero quella espressamente prescrittiva, che si rivolge all’ideale editoriale. Prospetta quindi criteri e parametri di valutazione assai precisi.

description: Two new self-assemblies based on zinc porphyrin dyes ZnPx-ZnPA (x = 1,2) were synthesized and used for dye-sensitized solar cells. Capping layer dyes consist of zinc porphyrin (ZnP) as core unit and carbazole (P1), phenothiazine (P2) as electron-donating group. The dye ZnPA contains carboxylic group as an anchor porphyrin with upper dyes (denoted as ZnP1 and ZnP2) formed dyads by coordination bonds of Zn-to-ligand self-assembled devices. The assembly modes were also verified by transmission electron microscopy (TEM). The influence of the upper porphyrins on molecular structure as well as photovoltaic performance was investigated via photophysical and electrochemical studies and calculations. With addition of the phenothiazine unit, the ZnP2-ZnPA possesses better light-harvesting capability with a significantly red-shifted Q-band. The photoelectrochemical efficiencies for ZnP2-ZnPA are better than those of ZnP1-ZnPA ascribed to larger Jsc and Voc.
Interference Alignment: From Degrees-of-Freedom to Constant-Gap Capacity Approximations

description: Interference alignment is a key technique for communication scenarios with multiple interfering links. In several such scenarios, interference alignment was used to characterize the degrees-of-freedom of the channel. However, these degrees-of-freedom capacity approximations are often too weak to make accurate predictions about the behavior of channel capacity at finite signal-to-noise ratios (SNRs). The aim of this paper is to significantly strengthen these results by showing that interference alignment can be used to characterize capacity to within a constant gap. We focus on real, time-invariant, frequency-flat X-channels. The only known solutions achieving the degrees-of-freedom of this channel are either based on real interference alignment or on layer-selection schemes. Neither of these solutions seems sufficient for a constant-gap capacity approximation. In this paper, we propose a new communication scheme and show that it achieves the capacity of the Gaussian X-channel to within a constant gap. To aid in this process, we develop a novel deterministic channel model. This deterministic model depends on the 0.5log(SNR) most-significant bits of the channel coefficients rather than only the single most-significant bit used in conventional deterministic models. The proposed deterministic model admits a wider range of achievable schemes that can be translated to the Gaussian channel. For this deterministic model, we find an approximately optimal communication scheme. We then translate this scheme for the deterministic channel to the original Gaussian X-channel and show that it achieves capacity to within a constant gap. This is the first constant-gap result for a general, fully-connected network requiring interference alignment.

Translating Text and Context: Translation Studies and Systemic Functional Linguistics. Volume 2: From Theory to Practice
Creators: name: Manfredi, Marina
Publisher: name: Alma Mater Studiorum - Università di Bologna
Year: 2012
Subjects: L-LIN/12 Lingua e traduzione - Lingua inglese

description: Following on the first volume (Manfredi 2008) focusing on the theoretical issues that link Systemic Functional Linguistics (SFL) and Translation Studies (TS), this second volume aims at demonstrating how they can be fruitfully exploited in the actual practice of translation. The book starts with the illustration of four models informed by SFL, which have been offered by renowned TS scholars and linguists (House 1977/1981, 1997; Bell 1991; Baker 1992/2011; Steiner 1997, 1998, 2004) and, to a different extent, have been applied to the practice of translation. Then, partly drawing on such models, as well as on the SFL analysis outlined by Miller (2005), the book puts forth a Hallidayan approach to translation practice, integrated with further insights from TS. The goal is to offer a tool for translation teaching, to be employed for both the production and evaluation of target texts, working with the language pair English/Italian. It is argued that the proposed SFL approach could be exploited to translate a wide range of text-types, from (semi-)specialized to literary. The model is also seen in operation through the practical analysis and translation, from English into Italian, of a diverse range of sample texts, from a variety of text-types. The book’s ultimate aim is to offer a contribution to translation education, in the hope that an SFL integrated approach could provide a systematic method for coping with the intricacies that languages, texts and contexts inevitably pose in a complex and multifaceted process like translation.

description: We consider the problem of learning a low-dimensional signal model from a collection of training samples. The mainstream approach would be to learn an overcomplete dictionary to provide good approximations of the training samples using sparse synthesis coefficients. This famous sparse model has a less well known counterpart, in analysis form, called the cosparse analysis model. In this new model, signals are characterised by their parsimony in a transformed domain using an overcomplete (linear) analysis operator. We propose to learn an analysis operator from a training corpus using a constrained optimisation framework based on L1 optimisation. The reason for introducing a constraint in the optimisation framework is to exclude trivial solutions. Although there is no final answer here for which constraint is the most relevant constraint, we investigate some conventional constraints in the model adaptation field and use the uniformly normalised tight frame (UNTF) for this purpose. We then derive a practical learning algorithm, based on projected subgradients and Douglas-Rachford splitting technique, and demonstrate its ability to robustly recover a ground truth analysis operator, when provided with a clean training set, of sufficient size. We also find an analysis operator for images, using some noisy cosparse signals, which is indeed a more realistic experiment. As the derived optimisation problem is not a convex program, we often find a local minimum using such variational methods. Some local optimality conditions are derived for two different settings, providing preliminary theoretical support for the well-posedness of the learning problem under appropriate conditions.

description: We calculate flow observables with the NeXSPheRIO ideal hydrodynamic model and make the first comparison to the complete set of mid-rapidity flow measurements made by the PHENIX collaboration in top energy Au+Au collisions. A simultaneous calculation of v_2, v_3, v_4, and the first event-by-event calculation of quadrangular flow defined with respect to the v_2 event plane (v_4{Psi_2}) gives good agreement with measured values, including the dependence on both transverse momentum and centrality. This provides confirmation that the collision system is indeed well described as a quark-gluon plasma with an extremely small viscosity, and that correlations are dominantly generated from collective effects. In addition we present a prediction for v_5.

description: (5Z, 7Z)-6, 8-dimethyl-9 H-tetrazolo [1,5-b] [1,2,4] triazepine (DMTT) is a fused ring nitrogen-rich compound, whose nitrogen content is 51.2%. In this study, the synthesis was carried out and the single crystal was cultivated for the first time. Gas generator based on DMTT with common oxidant was designed into formulation DMTT-KNO3. The combustion temperature, gas production rate, and mechanical safety of the gas generator were measured. In conclusion, DMTT/KNO3 formula has good combustion performance with low combustion temperature, fast gas production rate, and high safety in the process of movement and impact. The Inflation experiment of lifejacket airbag confirms that it is a kind of gas generator with potential development.

description: Malignant mesothelioma (MpM) is an aggressive, invariably fatal tumour that is causally linked with asbestos exposure. The disease primarily results from loss of tumour suppressor gene function and there are no 'druggable' driver oncogenes associated with MpM. To identify opportunities for management of this disease we have carried out polysome profiling to define the MpM translatome. We show that in MpM there is a selective increase in the translation of mRNAs encoding proteins required for ribosome assembly and mitochondrial biogenesis. This results in an enhanced rate of mRNA translation, abnormal mitochondrial morphology and oxygen consumption, and a reprogramming of metabolic outputs. These alterations delimit the cellular capacity for protein biosynthesis, accelerate growth and drive disease progression. Importantly, we show that inhibition of mRNA translation, particularly through combined pharmacological targeting of mTORC1 and 2, reverses these changes and inhibits malignant cell growth in vitro and in ex-vivo tumour tissue from patients with end-stage disease. Critically, we show that these pharmacological interventions prolong survival in animal models of asbestos-induced mesothelioma, providing the basis for a targeted, viable therapeutic option for patients with this incurable disease.

description: This work illustrates the joint use of a pilot study and an administrative data base for designing a probabilistic sample for an epidemiological survey. The target is to estimate the prevalence of an asymptomatic disease, the aortic valve stenosis (AS), in the elderly population of the city of Bologna, Italy. The novelty of the study is to reach the target population of elderly patients via a sample of their general practitioners (GPs). The pilot study was conducted in San Giovanni in Persiceto, a town in the province of Bologna. Overall information on patients and their GPs are available in the Azienda Unità Sanitaria Locale di Bologna (AUSL) data sets. Since the disease is asymptomatic, the sampling plan is designed to estimate the number of suspected patients that will be sent to further echocardiographic (ECO) examination. The probabilistic sampling plan aims at controlling the sources of randomness, via an appropriate clustering of the population of GPs. The number of practitioners to sample is fixed in advance. The subpopulations of patients to screen are also defined in advance and assigned to doctors. In this way the potential sources of randomness, due to the individual choices of doctors out of the definition of the experiment, are avoided. The number of elderly patients per doctor has been identified, from the pilot study, as an important factor able to influence the proportion of suspected patients sent to further examination. This feature is the leading factor of the sampling design, together with the clustering of the AUSL Bologna territory in NCPs, which emerges from the AUSL data set.
Exploring occupational therapists’ views about Nussbaum’s central human functional capabilities : an exploratory sequential mixed methods study
Creators: name: Mousavi, Seyedeh Tahmineh

description: BACKGROUND: The 21st century marks a shift in the perspective of care of people with disabilities with greater attention to individual human rights. An innovative approach related to human rights that provides a basis for conceptualizing and framing the rights of people with disabilities, is the Capability or Capabilities Approach. Developed by Sen and extended by Nussbaum, the approach advocates that fundamental human rights can be viewed as claims to certain basic capabilities. Nussbaum has proffered ten so-called Central Human Functional Capabilities (CHFCs). OBJECTIVE: To explore the views of Canadian occupational therapists (OTs) related to the CHFCs and their understanding and perceived relevance, with respect to their professional practice. METHODS: An exploratory sequential mixed methods design including an initial qualitative phase that informed a subsequent quantitative phase. Phase One consisted of semi-structured interviews with OTs (n=14) in British Columbia, Canada. The findings from Phase One generated 11 categories with 22 themes and 75 sub-themes. These findings informed the development of a questionnaire to survey Canadian OTs, nationally. A cross-sectional survey, registered with the Canadian Association of Occupational Therapists was conducted in Phase Two to determine the applicability of Phase One findings about the CHFCs to a broader group of OTs from across Canada. The survey was hosted at the website Fluid Surveys®. We sampled 780 OTs with a response of 109 (14%). RESULTS: Respondents understood the CHFCs as reflecting occupational therapy values. They perceived the CHFCs as relevant and consistent with established models of and approaches to occupational therapy practice including professionally-valued constructs of human rights and social justice as well as health and client-centered care. CONCLUSION: These findings unify and advance the conceptual bases for occupational therapy models and approaches by enabling OTs to better fulfill their professional mandate of addressing their clients’ needs from an overarching human rights perspective. Importantly, these results align occupational therapy services with client-centered practice, and human rights initiatives of the United Nations and World Health Organization. Our findings could be used by other health professions and across cultures to establish whether the Capabilities Approach is applicable across professional practices and health services.

description: BackgroundLevels of self-reported health do not always correlate with levels of physical disability in stroke survivors. We aimed to explore what underlies the difference between subjective self-reported health and objectively measured disability among stroke survivors.MethodsFace to face semi-structured interviews were conducted with stroke survivors recruited from a stroke clinic or rehabilitation ward in the UK. Fifteen stroke survivors purposively sampled from the clinic who had discordant self-rated health and levels of disability i.e. reported health as 'excellent' or 'good' despite significant physical disability (eight), or as 'fair' or 'poor' despite minimal disability (seven) were compared to each other, and to a control group of 13 stroke survivors with concordant self-rated health and disability levels. Interviews were conducted 4 to 6 months after stroke and data analysed using the constant comparative method informed by Albrecht and Devlieger's concept of 'disability paradox'.ResultsIndividuals with 'excellent' or 'good' self-rated health reported a sense of self-reliance and control over their bodies, focussed on their physical rehabilitation and lifestyle changes and reported few bodily and post-stroke symptoms regardless of level of disability. They also frequently described a positive affect and optimism towards recovery. Some, especially those with 'good' self-rated health and significant disability also found meaning from their stroke, reporting a spiritual outlook including practicing daily gratitude and acceptance of limitations. Individuals with minimal disability reporting 'fair' or 'poor' self-rated health on the other hand frequently referred to their post-stroke physical symptoms and comorbidities and indicated anxiety about future recovery. These differences in psychological outlook clustered with differences in perception of relational and social context including support offered by family and healthcare professionals.ConclusionsThe disability paradox may be illuminated by patterns of individual attributes and relational dynamics observed among stroke survivors. Harnessing these wider understandings can inform new models of post-stroke care for evaluation.

description: Il lavoro si incentra sull’analisi degli orientamenti giurisprudenziali più salienti, arricchita dai contributi della dottrina, in tema di pregiudizi non patrimoniali su beni costituzionalmente protetti della persona, con particolare riguardo al danno esistenziale. Si osserva che gli orientamenti giurisprudenziali in materia si sono tradotti in decisioni di diverso contenuto: alcune di esse negano il riconoscimento del pregiudizio esistenziale in capo alla vittima dell’illecito, altre lo riconoscono specificamente, e altre ancora, pur non prevedendolo espressamente, si mostrano comunque sensibili alla necessità di colmare la zona grigia di confine tra il danno biologico e il danno morale.
Secondo l’autrice tutte le fattispecie esaminate, sebbene fra loro eterogenee, hanno in comune la lesione di beni esistenziali della vittima, ovvero di diritti inerenti la libertà e la dignità della persona umana, che sono valori costituzionali di riferimento per il giudice nell’applicazione della legge e per il legislatore nella sua formazione.

description: In dieser Arbeit werden die Lösungen der quellenfreien Maxwellgleichungen in dem kompakten Raum S1 × S3 mit pseudoriemannscher Signatur ermittelt. Dabei sollen die Lösungen Eigenlösungen zu den Erzeugenden der Cartan-Unteralgebra der konformen Gruppe SU(2,2) sein. Die Cartan-Unteralgebra entspricht topologisch einem (maximalen) Torus, der durch die S1-Richtung und die zwei Heegaard-Tori der S3 aufgespannt wird. Die Komponenten der Lösungen lassen sich mit verwandten Riemannschen P-Funktionen, genauso wie die bereits bekannten Lösungen der Klein-Gordon-Gleichung, darstellen. Es werden zwei Spezialfälle untersucht, die zu interessanten Lösungen führen: Für ein skalares Feld mit diskretem Massenspektrum ist jeder vierte Wert (m0=2 Mod 4) verboten. Harmonische Vektorpotentiale, die nur entlang dem maximalen Torus agieren, lassen sich in drei Klassen mit je zwei freien Quantenzahlen (Eigenwerten) und einer vierten Klasse ohne freier Quantenzahl zusammenfassen. Wegen einer konformen Äquivalenz zum Minkowskiraum lassen sich die Lösungen auch im Rahmen einer konformen Feldtheorien interpretieren.
description: The solutions of Maxwell’s equations on the compact manifold S1 × S3 with pseudoriemannian signature are determined. Their form form is chosen with respect to the Cartan subalgebra of the conformal group SU(2,2) to be eigensolutions of the generating operators. Topologically the Cartan subalgebra corresponds to a (maximal) torus, created by the S1 direction and the two Heegaard tori of the 3 sphere. The components of the solutions are represented by contiguous Riemann’s P-functions, like the known solutions of the Klein-Gordon equation are represented too. In two special cases some interesting results occur. For a scalar field with discrete mass spectrum every fourth mass value (m0=2 Mod 4) is forbidden. Harmonic potentials of Maxwell’s equations with restriction on the maximal torus occur in three classes of solutions with two free quantum numbers (eigenvalues) each and a fourth class with fixed quantum numbers. As the manifolds S1 × S3 and M4 are conformal equivalent ones the solutions may be interpreted in a conformal field theory.

description: We investigate the impact of statistical and systematic errors on measurements of linear redshift-space distortions (RSD) in future cosmological surveys, analyzing large catalogues of dark-matter halos from the BASICC simulation. These allow us to estimate the dependence of errors on typical survey properties, as volume, galaxy density and mass (i.e. bias factor) of the adopted tracer. We find that measures of the specific growth rate β=f/b using the Hamilton/Kaiser harmonic expansion of the redshift-space correlation function ξ(r_p,π) on scales larger than 3/h Mpc are typically under-estimated by up to 10% for galaxy sized halos. This is significantly larger than the corresponding statistical errors, which amount to a few percent, indicating the importance of non-linear improvements to the Kaiser model to obtain accurate measurements of the growth rate. We compare the statistical errors to predictions obtained with the Fisher information matrix, based on the usual FKP prescription for the errors on the power spectrum. We show that this produces parameter errors fairly similar to the standard deviations from the halo catalogues, but only if applied to strictly linear scales in Fourier space (k<0.2 h/Mpc). Finally, we present an accurate scaling formula describing the relative error on β as a function of the survey parameters, which closely matches the simulation results in all explored regimes. This provides a handy and plausibly more realistic alternative to the Fisher matrix approach, to quickly and accurately predict RSD statistical errors expected from future surveys.

XMCD-PEEM

description: Abstract: The remanent domain structures of composite element magnetic barcodes have been imaged using photo-emission electron microscopy with contrast from x-ray magnetic circular dichroism (XMCD-PEEM) and analysed with reference to the results of micromagnetic simulations. The magnetisation configuration at the end of wide strips is found to be perpendicular to the majority magnetisation direction. This transitions to an incomplete rotation for nominal strip widths below 300 nm and is found to affect the mechanics of magnetisation reversal for nominal strip widths below 200 nm, owing to a difference in magnetisation orientation when an external magnetic field is applied that is just smaller than the magnetic coercivity of the structures and a corresponding change in reversal dynamics. This change in domain structure as strip width decreases is consistent with both the influence of shape anisotropy and with measurements of magnetic hysteresis. The magnetisation reversal characteristics of composite element structures are found to be dependent on the relative magnetisation configurations of neighbouring strips, which in turn are found to vary stochastically upon the application and removal of a magnetic field along the easy axis of the structure. It is found that the application of a canted field is necessary to ensure sharp, consistent magnetisation reversal of bits when writing a binary code. These results confirm that either improved lithography of narrower strips or non-rectangular elements would be necessary to further increase the number of individually programmable bits in a barcode.

description: The thermodynamics of a quantum system of layers containing perpendicularly oriented dipolar molecules is studied within an oscillator approximation for both bosonic and fermionic species. The system is assumed to be built from chains with one molecule in each layer. We consider the effects of the intralayer repulsion and quantum statistical requirements in systems with more than one chain. Specifically, we consider the case of two chains and solve the problem analytically within the harmonic Hamiltonian approach which is accurate for large dipole moments. The case of three chains is calculated numerically. Our findings indicate that thermodynamic observables, such as the heat capacity, can be used to probe the signatures of the intralayer interaction between chains. This should be relevant for near future experiments on polar molecules with strong dipole moments.

Ciò premesso l’articolo  propone una metodologia fortemente innovativa [denominata “Studio Guidato” (SG)] che dimostra la reversibilità dei danni suddetti,  a patto che si rinunci alla mentalità del difendersi  per acquisire quella di  un attacco frontale al virus, con forza superiore alla sua virulenza. Lo SG  ha armi assai valide per farlo (strumenti metodologici da lungo tempo approntate) che intende utilizzare secondo tre direttrici di attacco: due orientate a colpire due difetti  della didattica tradizionale (molto diffusi, ma anche abbastanza nascosti, sicchè di essi poco o nulla si parla) , la terza direttrice volta a convincere la classe docente (da tempo delusa per tanti motivi, tra cui quello di venire coinvolta da sempre in un volontariato che sembra non avere fine) che questa volta vale la pena partecipare. L’attacco è stato studiato, in una ricerca durata oltre sei anni, proprio a causa di quest’ultima direttrice, a lungo contrastata dai docenti per l’eccessivo stress a loro richiesto da una valutazione continua invero molto faticosa. Cinque lunghi anni per trovare il rimedio, poi di improvviso l’idea buona è venuta, nascosta in un ambito dall’apparenza utopistica:  da lì l’abbiamo estratta dimostrandone, al contrario, la concreta sua realtà. Si chiama auto-correzione del proprio compito da parte di ciascuno studente: una sorta di uovo di Colombo che ha tenuto in scacco per un paio  di anni la ricerca stessa, che poi l’ha reso distante anni-luce dall’utopia. Oggi lo consideriamo carta vincente di un progetto  sperimentale mono-annuale che terrà fede  al titolo di questo articolo.
Quantum Twist to Complementarity: A Duality Relation

description: Some recent works have introduced a quantum twist to the concept of complementarity, exemplified by a setup in which the which-way detector is in a superposition of being present and absent. It has been argued that such experiments allow measurement of particle-like and wave-like behavior at the same time. Here we derive an inequality which puts a bound on the visibility of interference and the amount of which-way information that one can obtain, in the context of such modified experiments. As the wave-aspect can only be revealed by an ensemble of detections, we argue that in such experiments, a single detection can contribute only to one subensemble, corresponding to either wave-aspect or particle aspect. This way, each detected particle behaves either as particle or as wave, never both, and Bohr's complementarity is fully respected.

description: Am Prostatakarzinomzentrum Dresden-Friedrichstadt wurde 09/2010 die multiparametrische MRT-Diagnostik der Prostata und 06/2011 die MRT-gestützte in-bore Prostatabiopsie etabliert. Mit Einführung der MRT-gestützten in-bore Prostatabiopsie wurden die klinischen und histologischen Parameter zu den durchgeführten Biopsien prospektiv in einer Datenbank erfasst. Die statistischen Auswertungen wurden mit SPSS v.20.0.0 vorgenommen und in grafischer sowie tabellarischer Form dargestellt. In der vorliegenden Arbeit werden die demografischen Parameter der untersuchten Patienten, die ermittelten Prostatakarzinom-Detektionsraten, die Lokalisationen der bioptierten Läsionen, die Lokalisationen mit Prostatakarzinomnachweis sowie die erfassten Komplikationen dargestellt. Bei Patienten, die sich nach Sicherung eines Prostatakarzinoms einer radikalen Prostatektomie unterzogen, wurde der Vergleich zwischen histologischem Ergebnis der Biopsie und histologischem Befund des Prostatektomie-Präparates vorgenommen. In der Diskussion werden die eigenen Ergebnisse an Hand der publizierten Literatur in den gegenwärtigen Kenntnisstand eingeordnet. Als wesentliche Ziele dieser Arbeit wurde dabei zum einen untersucht, ob die publizierten Detektionsraten auch in der Regelversorgung zu erreichen sind und zum anderen, ob mit der Technik der MRT-gestützten in-bore Prostatabiopsie Prostatakarzinome gesichert werden können, die mit dem Standardverfahren der transrektal ultraschallgestützten Biopsie auf Grund der Lokalisation einer Detektion möglicherweise entgehen.

description: This paper describes the successful flip chip
assembly of a broadband GaAs amplifier in microstrip
design. The flip chip technology used was thermo
compression (TC) flip chip bonding of the MMICs to gold
ball bumps bonded on the thin film patterned alumina
carrier.
Also, we report on the occurrence of parasitic parallel plate
(PPL) modes in the assemblies and we propose and
investigate a scheme to eliminate the modes which, to the
best our knowledge, have not been reported on before.
Finally we introduce our own flip chip transition equivalent
circuit and we use this model in ADS to compare the
simulated results with measurements. It is fair to say that
the equivalent circuit models the flip chip transition well.
This work was performed in the European MEDEA+
packaging project HIMICRO.

description: Martial law refers to the exercise of governmental power over the civilian population by military authorities. The use of martial law varied among belligerent countries, and its geographical scope and material extent changed over the course of the war. Enemy territories that came under military occupation were generally subjected to martial law. This article, however, focuses on martial law imposed within belligerent countries’ own pre-war borders.

description: A new method for characterization of HEMT
distortion parameters, which extracts the coefficents of
Taylor series expansion of Ids(Vgs,Vds), including all crossterms, from low-frequency harmonic measurements, has
been developed. The extracted parameters will be used
either in a Volterra series model around a fixed bias point
for third order characterization of small-signal Ids
nonlinearity, and in a large-signal model of Ids
characteristic, where its partial derivatives have been locally
characterized up to the third order in the whole bias region,
using a novel neural network representation. The two
models have been verified by harmonic measurements on a
AMS HEMT at 5 GHz.

description: In this paper the applicability of the VBIC95
model for consistent modeling of SiGe HBT devices is investigated.
A parameter extraction method is described, including
quasi-saturation, substrate parasitics, self-heating and weak
avalanche multiplication. Consistency between large-signal and
bias-dependent small-signal modeling is assured by extraction
several VBIC95 model parameters from a dedicated small-signal
model. The VBIC95 model is experimentally verified against DC
and RF measurements on a 8x0.35µm
2 area SiGe HBT device.

Analysing the Suzaku Spectra of the Broad-Line Seyfert 1 Galaxy CBS 126

description: We analysed new simultaneous \emph{Suzaku} and \emph{Swift} data of the Broad Line Seyfert 1 (BLS1) galaxy CBS 126. A clear Fe emission line and a strong soft excess are present in the source spectra. We fit the spectra with a relativistic reflection model and find the model tends to fit the data with a high iron abundance possibly due to the large soft excess present. By checking the difference and the RMS spectra, we find there is likely an absorption edge at $\sim$ 0.89 keV, which might be caused by oxygen or neon. We also produced an analysis of the time-resolved spectra in order to examine the existence of the edge. Although high iron abundance is required more in the time-resolved spectra, a model of solar iron abundance together with an absorption edge gives a more physical explanation. Variation of the ionisation parameter is an alternative, plausible explanation for the excess seen in the difference spectra. It is difficult to know if there are warm absorbers in this source from the current data. To further investigate the presence of possible warm absorbers, higher signal-to-noise low-energy data are needed. The work presented here tentatively suggests that the spectra of a BLS1 can be explained by a relativistic reflection model similar to that often seen in their narrow-line cousins.
