description: The present paper is the first in a series that addresses the calculation of the full one-loop corrections of dark matter (DM) annihilation cross-sections in the low mass region of the inert doublet model (IDM). We first review the renormalisation of the model both in a fully on-shell (OS) scheme and a mixed scheme combining on-shell (for the masses) and a $\overline{\rm MS}$ approach when the partial invisible width is closed and does not allow the use of a full OS scheme. The scale dependence introduced by the mixed scheme is shown to be tracked through an analysis of a parametrisation of the tree-level cross-section and the $β$ constant of a specific coupling. We discuss how to minimise the scale dependence. The theoretical uncertainty brought by the scale dependence leads us to introduce a new criterion on the perturbativity of the IDM. This criterion further delimits the allowed parameter space which we investigate carefully by including a host of constraints, both theoretical and experimental, including in particular, new data from the LHC. We come up with a set of benchmark points that cover three different mechanisms for a viable relic density of DM: {\it i)} a dominance of co-annihilation into a fermion pair, { \it ii)} annihilation into 2 vector bosons of which one is off-shell that requires the calculation of a $2 \to 3$ process at one-loop, {\it iii)} annihilation that proceeds through the very narrow standard model Higgs resonance. Since the $2 \to 3$ vector boson channel features in all three channels and is essentially a build up on the simpler annihilation to OS vector bosons, we study the latter in detail in the present paper. We confirm again that the corrected cross-sections involve a parameter that represents rescattering in the dark sector that a tree-level computation in not sensitive to.

description: Luminous blue variables (LBVs) are hot, very luminous massive stars displaying large quasi-periodic variations in brightness, radius,and photospheric temperature, on timescales of years to decades. The physical origin of this variability, called S Doradus cycle after its prototype, has remained elusive. Here, we study the feedback of stellar wind mass-loss on the envelope structure in stars near the Eddington limit. We perform a time-dependent hydrodynamic stellar evolutionary calculation, applying a stellar wind mass-loss prescription with a temperature-dependence inspired by the predicted systematic increase in mass-loss rates below 25 kK. We find that when the wind mass-loss rate crosses a well-defined threshold, a discontinuous change in the wind base conditions leads to a restructuring of the stellar envelope. The induced drastic radius and temperature changes, which occur on the thermal timescale of the inflated envelope, impose in turn mass-loss variations that reverse the initial changes, leading to a cycle that lacks a stationary equilibrium configuration. Our proof-of-concept model broadly reproduces the typical observational phenomenology of the S Doradus variability. We identify three key physical ingredients needed to trigger the instability: inflated envelopes in close proximity to the Eddington limit, a temperature range where decreasing opacities do not lead to an accelerating outflow, and a mass-loss rate that increases with decreasing temperature, crossing a critical threshold value within this temperature range. Our scenario and model provide testable predictions, and open the door for a consistent theoretical treatment of the LBV phase in stellar evolution, with consequences for their further evolution as single stars or in binary systems.

description: The Gauss hypergeometric functions 2F1 with arbitrary values of parameters are reduced to two functions with fixed values of parameters, which differ from the original ones by integers. It is shown that in the case of integer and/or half-integer values of parameters there are only three types of algebraically independent Gauss hypergeometric functions. The epsilon-expansion of functions of one of this type (type F in our classification) demands the introduction of new functions related to generalizations of elliptic functions. For the five other types of functions the higher-order epsilon-expansion up to functions of weight 4 are constructed. The result of the expansion is expressible in terms of Nielsen polylogarithms only. The reductions and epsilon-expansion of q-loop off-shell propagator diagrams with one massive line and q massless lines and q-loop bubble with two-massive lines and q-1 massless lines are considered.

description: We study the motion of self deforming bodies with non zero angular momentum when the changing shape is known as a function of time. The conserved angular momentum with respect to the center of mass, when seen from a rotating frame, describes a curve on a sphere as it happens for the rigid body motion, though obeying a more complicated non-autonomous equation. We observe that if, after time $ΔT$, this curve is simple and closed, the deforming body \'{}s orientation in space is fully characterized by an angle or phase $θ_{M}$. We also give a reconstruction formula for this angle which generalizes R. Montgomery\'{}s well known formula for the rigid body phase. Finally, we apply these techniques to obtain analytical results on the motion of deforming bodies in some concrete examples.

description: The Open Source (OS) software has progressively gained economic importance in recent years and more and more commercials firms are getting involved to various extents. The number of companies involved in different ways in software FOSS is very large. It is also very difficult to calculate them because it is not clear how they interfere. The name we give to this kind of Open Source software is HYBRID and this is the issue that will occupy us in this work. Initially, we analyze the original meaning of FOSS, then the hybrid software. After that we present a further investigation that is very close to ours and is one of the few documents that exist in the international literature on this particular subject. After that we conduct our own research, in which we collect data, mainly, from the known repository source forge.net. The purpose of this paper is to identify those variables that depend on whether a system is hybrid or not and to construct some models which can help us in some way to evaluate a hybrid software if it is successful or not. In the last part, conclusions are conducted and also further research developments are suggested.

description: Malaria is a disease caused by bites of infected female Anopheles mosquitoes and WHO recommends spraying of the inside of houses with residual insecticides known as Indoor Residual Spraying (IRS), as one of the methods to prevent and reduce transmission of malaria. However, the appearance of resistance to commonly used insecticides by Anopheles mosquitoes is threatening the success observed with this approach and consequently, WHO stresses the need for countries to develop and apply effective insecticide resistance management strategies. Hence, knowledge of major malaria vectors and their susceptibility to recommended insecticides is important for effective implementation of IRS. This study aimed at identifying Anopheles species and their susceptibility levels to two insecticides being used in Nsinze Sub-County, Namutumba district, Uganda where IRS is being undertaken. Susceptibility of adult mosquitoes reared from larvae collected from the breeding sites in the two study areas were assessed using WHO standard methods. The species composition was determined morphologically and using molecular tools. The findings show that at the dosage tested, the two insecticides were effective and can be used for control of Anopheles arabiensis, the mosquito species found in the study area.

description: Non-pregnant women clear parasites faster than pregnant. Non-immune environment in pregnant women may select for parasite populations associated with artemisinin resistance.
Objective: To identify antimalarial drugs resistance polymorphisms expressed in P. falciparum parasites in pregnant women versus non-pregnant women in Kenya.
Methods
Blood samples were collected at hours 0, 8, 24; days 7 and 28 from 75 malaria positive women. Arm1(pregnant in second trimester), arm2(pregnant in third trimester) and Arm3(non-pregnant). Samples were diagnosed for malaria using rtPCR. Merozoite surface proteins 1 and 2 genotyping done to determine recrudescence and reinfection. Single nucleotide polymorphisms genotyping for genes linked to drugs resistance and parasite population structure determination proceeded.
Results
40.0% of the 15 participants in arm1, 16.7% of the 12 arm2 participants and 5.6% of the 18 arm3 participants were Plasmodium positive Hr24. At day7, however, 66.7% arm1 participants were still Plasmodium positive while arm2 and 3 had both cleared the parasite. All P. falciparum infections cleared after 24hrs of treatment. 225 of 375 samples proceeded to subsequent analysis.
Conclusion
Plasmodium positives on days 7 and 28 were confirmed non-falciparum reinfections. This study presents genotypic properties of malaria parasites in pregnant and non-pregnant women and advises on expression of genes associated with resistance to artemisinin between the three arms.

description: About 74% of malaria diagnoses globally are done using malaria Rapid Diagnostic Test (RDT). The accuracy of PfHRP2 based RDTs can be impaired by lack of target antigen in the parasite. WHO criteria require >95% accuracy in diagnosis.
Objective: To determine the frequency and trends of PfHRP2 and PfHRP3 gene mutations and deletions in four of five malaria transmission regions in Kenya.
Methods: 350 samples collected between 2003 and 2017 were diagnosed for malaria by microscopy, RDT, and PCR. All P. falciparum PCR positive samples were processed and analysed to determine the presence or absence of PfHRP2 and PfHRP3.
Results
 37(16.8%) of 220 P. falciparum were negative by PfHRP2 based RDT. This appears to suggest the possibility of parasites lacking PfHRP2 and PfHRP3. However, PCR amplification showed that PfHRP2 and PfHRP3 genes were present in these 37 samples.
Conclusion
PfHRP2 and PfHRP3 genotyping did not clarify variability in RDT reactivity. Therefore, sequence analyses of these fragments are underway for clarification of mutations in these genes and the population structure of the parasites.
Findings will guide policy decision on relevance of continued deployment of PfHRP2 based RDTs across Kenya. Temporal and population structure analysis will verify role of evolution in distribution of PfHRP2 and PfHRP3 aberrant genotypes.

description: M. tuberculosis complex Uganda (MTBC-Ug)genotype is responsible for majority (68 %) of tuberculosis (TB) cases in peri-urban Kampala-Uganda, the reasons for this is unknown. In the current study we set out to understand why MTBC-Ug genotype is the main cause of tuberculosis..
Objectives To develop an assay that accurately identifies MTBC genotypes circulating in peri-urban Kampala To seek for TB patient characteristic that can be used to explain the dornimance
Method
Using MTBC lineage specific genetic markers we developed an assay that can accurately identifies MTBC, we used the assay to genotype 1746 MTBC isolates from adult patients enrolled in household study between (1992-2010) in peri-urban Kampala. The resultant data was used to seek for association between MTBC genotypes and patient clinical/demographic characteristics.

Results
The data showed 3 main MTBC genotypes circulating in peri-urban Kampala and none of these was associated with increased lung cavitation (holes in the lung) a measure of disease transmission (OR=1.08; CI at 95%= 0.78-1.51). However, smoking (OR=4.8; CI=3.33-6.84), cough with blood (OR=2; CI=1.10-2.42); low income (OR=2; CI=1.47-3.01) and HIV (OR=0.62; CI= 0.45-0.84) are risk factors for cavitary tuberculosis.

Conclusion
Three MTBC genotypes (lineages) circulating in peri-urban Kampala and none of these is associated with increased transmission

description: Objective: This study detected Mycobacterium tuberculosiscomplex (MTBC) species and characterized their drug-susceptibility-testing (DST) profile, for guiding the selection of drugs suitable for treating patients with rifampicin-resistant tuberculosis (RR-TB).
Methods: Fifty-four patients with RR-TB were enrolled at the Kibong’oto Infectious Diseases Hospital in Tanzania. Detection of Mycobacteria species was done using smear-microscopy, tuberculosis-culture and molecular methods.
Results:Of 54 patients, 38 (70.4%) were male with a median-age of 42 (IQR, 34-54) years. Nineteen (36.5%) had TB with HIV co-infection, 29 (53.7%) had previous TB treatment and 32 (59.3%) had a body-mass-index of <18.5 kg/m2. Patients delayed to attend at the hospital by 84 (IQR, 56-252) days. Ten (18.5%), 26 (48.1%) and 28 (51.9%) patients had MTBC by Smear-microscopy, TB-culture and molecular-methods respectively. One HIV-infected patient had M. intracellularae and was phenotypically resistant to all anti-TB drugs. Of the 28 MTBC detected-by molecular methods, 15 (53.6%) were resistant to rifampicin, 7 (25.0%) to isoniazid and 6 (21.4%) were, to both. None had resistance to aminoglycosides/capreomycin or fluoroquinolones.
Conclusion:M. tuberculosis was the commonest MTBC species and all were susceptible to second-line anti-TB drugs. M. intracellularae is common in people positive for HIV, with cystic fibrosis and cavitary lesions.

description: Objectives:Patients with type 2 diabetes mellitus (T2DM) are three times more at risk of acquiring tuberculosis (TB) compared to non-diabetic individuals. Our study aim was to find out the prevalence of latent TB among newly diagnosed T2DM patients attending the diabetic clinic at Mulago National Referral Hospital (MNRH) in Kampala, Uganda.

Methods:This was a case control study carried out between October 2017 and March 2018. Patients seeking care at MNRH were screened, and 103 newly diagnosed T2DM cases enrolled. Controls of similar age and gender were also screened, and 201 enrolled. Latent TB was diagnosed using a blood test and chest X-rays.

Results:The prevalence of latent TB was 73% among cases and 71% among controls. Most of the cases and controls were female (69% and 71% respectively). Cases had poor blood sugar control and were more overweight. Also, the cases had worse symptoms than controls such as higher blood pressure and cholesterol levels. About 17% of the T2DM cases had signs of kidney disease. Among controls, 10% were pre-diabetic.

Conclusions:There was no difference in the prevalence of latent TB between T2DM cases and their controls. The burden of latent TB was high among both populations. T2DM cases had worse symptoms, predisposing them to more complications and death.

description: The proliferation of turbulence in subcritical wall-bounded shear flows involves spatially localised coherent structures. Turbulent spots correspond to finite-time nonlinear responses to pointwise disturbances and are regarded as seeds of turbulence during transition. The rapid spatial decay of the turbulent fluctuations away from a spot is accompanied by large-scale flows with a robust structuration. The far field velocity field of these spots is investigated numerically using spectral methods in large domains in four different flow scenarios (plane Couette, plane Poiseuille, Couette-Poiseuille and a sinusoidal shear flow). At odds with former expectations, the planar components of the velocity field decay algebraically. These decay exponents depend only on the symmetries of the system, which here depend on the presence of an applied gradient, and not on the Reynolds number. This suggests an effective two-dimensional multipolar expansion for the far field, dominated by a quadrupolar flow component or, for asymmetric flow fields, by a dipolar flow component.

description: Stable, hydrogen-burning, M dwarf stars comprise about 75% of all stars in the Galaxy. They are extremely long-lived and because they are much smaller in mass than the Sun (between 0.5 and 0.08 MSun), their temperature and stellar luminosity are low and peaked in the red. We have re-examined what is known at present about the potential for a terrestrial planet forming within, or migrating into, the classic liquid-surface-water habitable zone close to an M dwarf star. Observations of protoplanetary disks suggest that planet-building materials are common around M dwarfs, but N-body simulations differ in their estimations of the likelihood of potentially-habitable, wet planets residing within their habitable zones, which are only ~ 1/5 to 1/50 of the width of that for a G star. Particularly in light of the claimed detection of the planets with masses as small as 5.5 and 7.5 MEarth orbiting M stars, there seems no reason to exclude the possibility of terrestrial planets. Tidally locked synchronous rotation within the narrow habitable zone doesn't necessarily lead to atmospheric collapse, and active stellar flaring may not be as much of an evolutionarily disadvantageous factor as has previously been supposed. We conclude that M dwarf stars may indeed be viable hosts for planets on which the origin and evolution of life can occur. A number of planetary processes such as cessation of geothermal activity, or thermal and non-thermal atmospheric loss processes may limit the duration of planetary habitability to periods far shorter than the extreme lifetime of the M dwarf star. Nevertheless, it makes sense to include M dwarf stars in programs that seek to find habitable worlds and evidence of life.

description: Objective: Bovine tuberculosis (BTB) is an endemic zoonosis in Morocco with estimated prevalence at 18%, and 33% at the individual and the herd level respectively, but the human M. bovis burden needs further clarification.

Methods: A simple compartmental deterministic mathematical model for BTB transmission in cattle and humans was established. Differential equations were used to model the different pathways between the compartments for cattle and humans. Scenarios of test and slaughter were simulated to determine the effects of varying the proportion of tested animals (p) on the time to elimination of BTB in cattle and humans.

Results: The time to freedom from disease ranged from 75 years for p = 20% to 12 years for p = 100%. For p values higher than 40%, cost ranged from €1.47-1.60 billion with a time frame of 12 to 32 years to reach freedom from disease. The model suggest that using a 2mm cut-off instead of a 4mm cut-off in the tuberculin skin test would result in cheaper and more rapid elimination programs.

Conclusion: This analysis informs Moroccan bovine tuberculosis control policy regarding time frame, range of cost and levels of intervention. The current control strategy should be improved to reduce BTB prevalence and its burden in humans and animals.
Nuclear proliferation in South Asia: more may not be better
Creators: name: Bain, William W.
Publisher: name: University of British Columbia

description: Most scholars and policy-makers hold the view that nuclear proliferation is inherently dangerous, while others, most notably Kenneth Waltz, view the slow spread of nuclear weapons as conducive to international peace and stability. This study is concerned with evaluating the rigor of Waltz's rather controversial perspective. Waltz's nuclear peace argument contains two significant errors: first, its neorealist theoretical foundation is blind to many aspiring nuclear powers and, second, Waltz mistakenly assumes that nuclear weapons necessarily enhance a state's overall security. These errors may be overcome by adopting a subsystemic unit of analysis in lieu of Waltz's systemic approach. Fully considering the exceptional characteristics of nuclear weapons suggests that nuclear weapons states are functionally different from non-nuclear weapons states, Waltz's notion of capabilities should disaggregated into discrete sectors, and nuclear weapons have qualitatively changed the basic character of the international system. Constructing a subsystem on the basis of differentiating states by their nuclear weapons status and by discerning patterns of nuclear proliferation driven strategic interaction yields an analytical unit which is cognizant of all states in the system, sensitive to the limitations of nuclear power, and is sustainable within the neorealist/structural realist perspective. This analytical approach is used to assess the impact of nuclear proliferation on peace and stability in a subsystem comprised of China, India, and Pakistan. It is evident that nuclear weapons do not alleviate the principal sources of insecurity which afflict these states. When considered in this South Asian context, Waltz's nuclear peace argument should be rejected in favor of more conventional approaches to nuclear nonproliferation.

description: Background: The agenda for malaria elimination and eradication necessitate the development of novel strategies to prevent the spread of the disease. The spread of malaria relies on female mosquito which ingests, during their blood meal, one form of the parasite called gametocyte. Biological parameters defining gametocyte transmissibility to the mosquito are not well understood. The identification of biological markers associated with gametocyte transmissibility can help in the development of new therapeutic strategies.

Objectives: The goal of this work was to identify biomarkers associated with the transmission of gametocytes in the field.

Methods: From October to December 2017, gametocyte positive volunteers were enrolled. Venous blood was collected for blood serological testing and mosquito feeding experiments. Gametocytes transmissibility was assessed by dissecting fed mosquitos 8 days post-feeding and quantifying the number of parasite in the mosquito.

Results:70 volunteers were enrolled and 28% of the volunteer’s blood results in the formation of oocyst in the mosquito. Serological testing identified 26 markers associated with gametocytes transmissibility.

Conclusion: The identification of biomarkers associated with malaria transmission is providing us with potential targets for the development of transmission-blocking strategies as well as new tools for malaria transmission screening.

description: (Abridged) We present deep WSRT observations of neutral hydrogen in 12 nearby elliptical and lenticular galaxies. The selected objects come from a representative sample of nearby galaxies earlier studied at optical wavelengths with the integral-field spectrograph Sauron. We detect HI - both in regular discs as well as in clouds and tails off-set from the host galaxy - in 70% of the galaxies. This detection rate is much higher than in previous, shallower single-dish surveys, and is similar to that for the ionised gas. The results suggest that at faint detection levels the presence of HI is a relatively common characteristic of field early-type galaxies. The observed total HI masses range between a few times 10^6 Msun to just over 10^9 Msun. The presence of regular disc-like structures is a situation as common as HI in offset clouds and tails around early-type galaxies. All galaxies where HI is detected also contain ionised gas, whereas no HI is found around galaxies without ionised gas. Galaxies with regular HI discs tend to have strong emission from ionised gas. In these cases, the similar kinematics of the neutral hydrogen and ionised gas suggest that they form one structure. We do not find a clear trend between the presence of HI and the global age of the stellar population or the global dynamical characteristics of the galaxies. Our observations support the idea that gas accretion is common and does not happen exclusively in peculiar early-type galaxies. For the majority of the cases the gas is likely acquired through merging, but the lack of correlation with the stellar population age suggests that smooth, cold accretion could be an alternative scenario, at least in some galaxies. In either cases, the data suggest that early-type galaxies continue to build their mass up to the present.

description: The purpose of the present diplomatic paper, concerning the Comparative study of the candidates of the political parties PASOK, ND and LAOS on the B΄ district of Thessaloniki, in the elections of September 16th 2007, is to study their most important political character. We start by defining five categories of criteria that include fourteen criteria of comparison. The assessment of the candidates is scheduled by the climate 1-4. By this assessment we create groups of the candidates using the programme spss in order to process the results. With the same programme, we categorize the candidates based on their electoral results in order to define their similarities and deferences. This procedure indicates the groups of the candidates with the same or opposite elements of political characteristics that gives us the final image of the candidates of the B΄ district of Thessaloniki.

description: We consider a single field governed expansion of the universe from a five dimensional (5D) vacuum state. Under an appropiate change of variables the universe can be viewed in a effective manner as expanding in 4D with an effective equation of state which describes different epochs of its evolution. In the example here worked the universe fistly describes an inflationary phase, followed by a decelerated expansion. Thereafter, the universe is accelerated and describes a quintessential expansion to finally, in the future, be vacuum dominated.

description: Objectives
Onchocerciasis is a parasitic disease with a high socio-economic burden, particularly in sub-Saharan Africa. With the numerous challenges facing the current treatment and control measures, a preventive/curative vaccine could prove invaluable to achieving the elimination goal. Several observations show that development of a vaccine against this disease is possible.

Methods
An immuno-informatics approach was applied to design a vaccine peptide with multiple antigen binding sites consisting of linear B-cell and T-cell binding sites of proteins reported to be potential novel vaccine candidates. The 3D structure was predicted, refined and validated using bioinformatics tools.

Results
The physical and chemical properties measured showed that the predicted protein is heat-stable and can stay for up to 30 hours in a culture of human white blood cells. Protein-protein docking of the chimeric vaccine peptide with the immune receptor, TLR4 protein predicted favourable binding. A simulation of the immune response predicted significantly high levels of antibodies and other immune components that are implicated in the development of immunity to the disease. Comparing the predicted protein to other related nematode species that cause human and livestock diseases showed that several binding sites are similar.

Conclusion
The predicted protein showed better antigenic properties and cross-protection as compared to current vaccine candidates.

description: A new approach to thermo-quantum diffusion is proposed and a nonlinear quantum Smoluchowski equation is derived, which describes classical diffusion in the field of the Bohm quantum potential. A nonlinear thermo-quantum expression for the diffusion front is obtained, being a quantum generalization of the classical Einstein law. The quantum diffusion at zero temperature is also described and a new dependence of the position dispersion on time is derived. A stochastic Bohm-Langevin equation is also proposed.

description: Pre-proof versionAdvanced Oxidation Processes and in particular photo-Fenton, represent promising strategies of pathogen inactivation in wastewater effluents. Nevertheless, its full potential is not yet unlocked, as the efficacy of photo-Fenton against viruses has not been deeply explored. In this work, we characterize the effect of major parameters (Fe species and concentration, solar irradiance, pH and microbial competition) on the inactivation of MS2 Coliphage by the photo-Fenton process. The use of Fe(II) salts, under any combination of H2O2 concentration, sunlight irradiance or starting pH (6-8), induced a faster inactivation compared to their Fe(III) counterparts. Moreover, ICP-MS analyses revealed that starting with Fe(II) resulted to higher amount of iron in solution longer than Fe(III), which led to higher inactivation kinetics. Even so, a 4-log MS2 inactivation was achieved upon exposure to 600 W/m2 for 30 minutes in presence of Fe(III) and H2O2 (1:1 ratio). Furthermore, the inactivation of MS2 was only slightly decreased in presence of the bacterial host, suggesting a low competition for the oxidants in the bulk. The enhancement of iron solubilization through its complexation by organic matter present in wastewater was also investigated, observing an efficient viral inactivation despite the presence of reactive oxygen species (ROS) scavengers. The present data have been used to propose a simple model describing MS2 photo-Fenton inactivation in wastewater. Finally, the pathway describing the photo-Fenton-induced MS2 inactivation in wastewater was proposed, in presence or absence of bacteria.

description: Weakly spin-orbit coupled electron and hole spins in organic light-emitting diodes (OLEDs) constitute near-perfect two-level systems to explore the interaction of light and matter in the ultrastrong-drive regime. Under such highly non-perturbative conditions, the frequency at which the spin oscillates between states, the Rabi frequency, becomes comparable to its natural resonance frequency, the Larmor frequency. For such conditions, we develop an intuitive understanding of the emergence of hybrid light-matter states, illustrating how dipole-forbidden multiple-quantum transitions at integer and fractional g-factors arise. A rigorous theoretical treatment of the phenomena comes from a Floquet-style solution to the time-dependent Hamiltonian of the electron-hole spin pair under resonant drive. To probe these phenomena experimentally requires both the development of a magnetic-resonance setup capable of supporting oscillating driving fields comparable in magnitude to the static field defining the Zeeman splitting; and an organic semiconductor which is characterized by minimal inhomogeneous broadening so as to allow the non-linear light-matter interactions to be resolved. The predicted exotic resonance features associated with the Floquet states are indeed found experimentally in measurements of spin-dependent steady-state OLED current under resonant drive, demonstrating that complex hybrid light-matter spin excitations can be formed and probed at room temperature. The spin-Dicke state arising under strong drive is insensitive to power broadening so that the Bloch-Siegert shift of the resonance becomes apparent, implying long coherence times of the dressed spin state with potential applicability for quantum sensing.

description: Η παγκόσμια οικονομία γνώρισε το 2008 τη δεύτερη μεγαλύτερη οικονομική κρίση μετά το 1929. Το σημαντικότερο πρόβλημα, όμως, που καλούνται να αντιμετωπίσουν σήμερα οι οικονομίες και οι επιχειρήσεις είναι να δουν τα λάθη που οδήγησαν στην κρίση και πως θα επανέλθει η πολυπόθητη οικονομική ανάκαμψη. Μέχρι πρότινος επικρατούσε η άποψη ότι η κρίση αυτή είναι τόσο μεγάλη που συντάραξε το «καπιταλιστικό σύστημα» και τις αρχές του. Επομένως, απώτερος σκοπός είναι η πρόβλεψη των επερχόμενων κρίσεων μέσω της θεμελιώδους και τεχνικής ανάλυσης. Η υιοθέτηση μεθόδων προβλέψεων και η ελαχιστοποίηση των ριψοκίνδυνων επενδύσεων είναι στην ατζέντα των στελεχών των επιχειρήσεων και των πολιτικών. Οι ριψοκίνδυνες επενδύσεις ήταν χρηματοοικονομικά προϊόντα που στηρίχθηκαν στα στεγαστικά δάνεια των ΗΠΑ και διαπραγματεύονταν σε όλες τις αγορές του κόσμου. Η επενδυτική Τράπεζα Lehman Brothers ήταν μια από τις μεγαλύτερες επενδυτικές Τράπεζες και η κατάρρευση της, λόγω της υψηλής έκθεσης σε αυτά τα χρηματοοικονομικά προϊόντα, προκάλεσε πανικό. Η συμβολή της τεχνικής και της θεμελιώδης ανάλυσης στην πρόβλεψη των κρίσεων είναι κάτι που θα βοηθήσει τους επενδυτές στις μελλοντικές τους επενδύσεις και θα μπορέσουν να προβλέψουν την μελλοντική κρίση, χωρίς ωστόσο να διαβλέψουν το μέγεθος της. Ο σκοπός αυτής της εργασίας είναι να παρουσιάσει τα χρηματοπιστωτικά προϊόντα στα οποία οφείλεται η σημερινή κρίση, η χρονική εξέλιξη της κρίσης, η συμβολή της θεμελιώδους και της τεχνικής ανάλυσης και, τέλος, η σύγκριση της με την κρίση του 1929.
description: World economy met 2008 the second biggest crisis after 1929. The most important problem, though, that economies and businesses need to deal with today is to see the mistakes that lead to the crisis and how the much desired economical recovery will come back. Until recently it was prevailed that this crisis is so big that shocked the "capital system" and its principals. Therefore, the final aim is the forecast of future crisis through fundamental and technical analysis. The adoption of methods of forecasts and the minimization of risky investments are in the agenda of executives of enterprises and politicians. Risky investments were financing products that were based in the housing loans of USA and were negotiated worldwide. The Investment Bank Lehman Brothers was one of the largest investment banks and its collapse caused panic. The contribution of technical and fundamental analysis in the forecast of crises is something that will help the investors in their future investments and might forecast the future crisis, without being able to predict their size. The aim of this study is to present the financial products that may have led to the current crisis, the time development of crisis, the contribution the fundamental and technical analysis and, finally, its comparison with the crisis of 1929.
