description: Rarita-Schwinger (RS) quantum free field is reexamined in the context of deformation quantization. It is found out that the subsidiary condition does not introduce any change either in the Wigner function or in other aspects of the deformation quantization formalism, in relation to the Dirac field case. This happens because the vector structure of the RS field imposes constraints on the space of wave function solutions and not on the operator structure. The RS propagator was also calculated within this formalism.

Weak hyperbolicity of cube complexes and quasi-arboreal groups
Creators: name: Hagen, Mark F.
Publisher: name: arXiv
Year: 2011
Subjects: subject: Group Theory (math.GR)
subject: FOS: Mathematics

description: We examine a graph $Γ$ encoding the intersection of hyperplane carriers in a CAT(0) cube complex $\widetilde X$. The main result is that $Γ$ is quasi-isometric to a tree. This implies that a group $G$ acting properly and cocompactly on $\widetilde X$ is weakly hyperbolic relative to the hyperplane stabilizers. Using disc diagram techniques and Wright's recent result on the aymptotic dimension of CAT(0) cube complexes, we give a generalization of a theorem of Bell and Dranishnikov on the finite asymptotic dimension of graphs of asymptotically finite-dimensional groups. More precisely, we prove asymptotic finite-dimensionality for finitely-generated groups acting on finite-dimensional cube complexes with 0-cube stabilizers of uniformly bounded asymptotic dimension. Finally, we apply contact graph techniques to prove a cubical version of the flat plane theorem stated in terms of complete bipartite subgraphs of $Γ$.

description: I give an elementary introduction to the study of gauge theories coupled to fermions with many degrees of freedom. Besides their intrinsic interest, these theories are candidates for nonperturbative extensions of the Higgs sector of the Standard Model. While related to QCD, these systems can exhibit very different behavior from it: they can possess a running gauge coupling with an infrared attractive fixed point (IRFP). I briefly survey recent lattice work in this area.

description: In this paper, we investigate the possibility of improving the performance of the metaheuristic algorithm on rigid target functionals by hybridizing the algorithm with the Rosenbrock method. In the course of the work, hybrid algorithms of differential evolution were created, in which the Rosenbrock method is performed with different probabilities and the optimal one was chosen.The chosen modification was tested on functionals of different dimensions and gully degrees in order to compare the hybrid method with the original ones. Tests have shown that the hybrid method is in most cases more effective than the differential evolution. This means that hybridization of the metaheuristic method with the Rosenbrock method helps to increase the speed and accuracy of the solution on stiff functionals.
Harmonizing Values, Not Laws: The CISG and the Benefits of a Neo-Realist Perspective
Creators: name: Mazzacano, Peter J.
Publisher: name: Nordic Journal of Commercial Law
Year: 2008

description: Legal Realism has been deemed as one of the most important jurisprudential movements in Western society during the twentieth century.2 This group, which was by no means coherent, flourished particularly in the 1920s and 1930s at Yale and Columbia law schools, originated with such scholars as, Oliver Wendell Holmes, John Chipman, and Karl Llewellyn.3 Although it has been thought that Realism is “dead”, having been put to rest by H.L.A. Hart’s derisive critique,4 there has been renewed interest in the subject in recent years.5 While it is difficult to speak of a single, comprehensive theory belonging to this group, certain unifying themes can be discerned from the writings of the Realists’, particularly those that concern rule-skepticism and the indeterminacy of law.6 At the risk of simplifying the Legal Realist perspective, the conventional view holds that Legal Realism is a theory7 that law is based, not on formal rules or principles, but instead on judicial decisions that originate from social interests and public policy. In other words, beneath a veneer of scientific and deductive reasoning of “mechanical jurisprudence”8 are legal rules and concepts—that is, legal doctrine—that are often indeterminate, and these are rarely as neutral as they appear. In the words of Hart, the Realists’ theory of law holds the view that “talk of rules is a myth, cloaking the truth that law consists simply of the decisions of courts and the prediction of them”.9 This Realist theory of law is usually analyzed solely within the context of domestic case law and jurisprudence. But how does the Realist theory of law apply in a global setting, that is, within the context of international law? Particularly, would the Realists have us believe that efforts to create uniform national laws through international treaties or conventions are subject to the same degree of uncertainty as domestic rule-making? In other words, can international conventions be as indeterminate as domestic legislation? Considering that the objective of uniform law conventions is to standardize judicial rule-making across jurisdictions appears to directly challenge the Realist notion that such laws are too indeterminate to be a significant influence on, or predictor of, a judges’ decision, how do we explain the development of functional uniformity10 in legal doctrine related to an international convention?

RECOVERABILITY OF THE BUYER'S LOST RESALE PROFIT UNDER CISG
Creators: name: Raczynska, Magdalena
Publisher: name: Nordic Journal of Commercial Law
Year: 2007

description: It is a common conjuncture that the right to claim damages as a result of a breach of contract plays the most pivotal role among the remedies available to an aggrieved party.1 Hence, the importance of taking a better look at damages that can be recovered for a particular type of loss. In this essay an attempt is made to identify some of the problems that arise before the courts when granting damages for buyer’s lost resale profit under the UN Convention on the Contracts for the International Sale of Goods.2 The practice in the area seems to be far from clear or consistent and academic literature is not always lending a helping hand. The purpose of the first part of the essay is to sketch the notion of lost resale profit against a broader background of the law of damages. Further and more detailed analysis will oscillate around three issues which in practice appear to be central to the recoverability of the lost resale profit by the buyer, namely the foreseeability, calculation and mitigation of that loss. It is fascinating to see how the concrete and abstract considerations, general principles and their detailed applications are all masterfully interwoven in the colourful fabric of the lost resale profit issue. The author hopes to shed some light on the various patterns embellishing this fine material and, if possible single out the most prominent strands.

description: We have investigated the necessary conditions that prevent phantom inflation from being eternal. Allowing additionally for a nonminimal coupling between the phantom field and gravity, we present the slow-climb requirements, perform an analysis of the fluctuations, and finally we extract the overall conditions that are necessary in order to prevent eternality. Furthermore, we verify our results by solving explicitly the cosmological equations in a simple example of an exponential potential, formulating the classical motion plus the stochastic effect of the fluctuations through Langevin equations. Our analysis shows that phantom inflation can be finite without the need of additional exotic mechanisms.

description: The vital originary moments of democracy rely on the work of dissidents using creative means to contest exclusion and domination. Much of contemporary political theory continues to mine the Western tradition of political thought for such democratic resources. Augmenting those well-known iterations, I look outside the confines of Western political theory to locate other histories and conceptual resources that inform ongoing resistance against exclusionary structures across time and place. Focusing on narratives of democratic agency in both Western and non-Western cases, this dissertation uncovers texts and actions that show how those outside or at the margins of different political orders empower themselves and work to radically reconstitute those societies. Against circumscribed definitions of “the people” instituted by executive and juridical authorities, those left out of the political realm evince what I term exilic thinking to challenge such exclusionary scripts and extend the scope of the demos. I argue that narratives of democratic empowerment are not merely the products of Western political theory, but transcultural and ubiquitous. Using a narratological method that combines insights from Hannah Arendt and Edward Said, I survey a select set of historical moments in Western and non-Western experience to identify worldly manifestations of agency in texts and practices underappreciated for their democratic significance. The democratic moments I analyse include dissident Sufism in the wake of the Islamic Golden Age; the poetics of exile in early Renaissance Florence; decolonial thought moving from the Americas to Africa and the Middle East; and contemporary struggles against exclusion and domination in Iran and North America. Taken together, these explorations shed new light on practices of resistance and collective self-governance, contributing to theoretical advances in the study of democracy and comparative political theory. Finally, I provide a praxis-oriented approach at the end of my dissertation to consider the efficacy of sharing aesthetic, literary, and exilic narratives in enabling common world-building practices in conditions of deep diversity.

description: ΙΣΤΟΡΙΚΟ: Οι διαθέσιμοι πόροι για την υγεία είναι περιορισμένοι. Κατά συνέπεια, ο διαμοιρασμός τους χρειάζεται να γίνεται υπεύθυνα, αποτελεσματικά και αποδοτικά. Η οικονομική αξιολόγηση αποτελεί σημαντική διαδικασία ώστε να επιλέγονται και να εφαρμόζονται οι κατάλληλες παρεμβάσεις προαγωγής υγείας με σκοπό την επίτευξη των στόχων της δημόσιας υγείας. Κριτήριο αξιολόγησης θεωρείται η αποδοτικότητα. Σκοπός της παρούσας συστηματικής ανασκόπησης είναι η εκτίμηση της αποδοτικότητας των παρεμβάσεων προαγωγής υγείας των τριών επιπέδων πρόληψης ( πρωτογενής , δευτερογενής, τριτογενής) σε παγκόσμιο επίπεδο μέσω της αναζήτησης συστηματικών ανασκοπήσεων. ΜΕΘΟΔΟΛΟΓΙΑ: Πραγματοποιήθηκε συστηματική ανασκόπηση σύμφωνα με τις κατευθυντήριες γραμμές του εργαλείου PRISMA. Η αναζήτηση των επιμέρους συστηματικών ανασκοπήσεων διεξήχθη στις βάσεις δεδομένων MEDLINE και Pubmed, με λέξεις-κλειδιά: «Αποδοτικότητα» και «Προληπτικές Παρεμβάσεις». Ελέγχθηκαν για ένταξη, με βάση τα κριτήρια επιλεξιμότητας τα οποία ήταν : α) να είναι συστηματική ανασκόπηση, β) κείμενο στην αγγλική γλώσσα, γ) έτος δημοσίευσης 2011-2021, δ) να εμπεριέχονται παρεμβάσεις και δείκτες αποτελεσματικότητας, αποδοτικότητας, ε) να καταγράφεται αν ήταν αποδοτικές ή όχι. Κατηγοριοποιήθηκαν στο ανάλογο επίπεδο πρόληψης και καταγράφηκαν τα αποτελέσματα. ΑΠΟΤΕΛΕΣΜΑΤΑ: Συμπεριλήφθηκαν συνολικά 26 συστηματικές ανασκοπήσεις, ανεξαρτήτου γεωγραφικής κατανομής και δείγματος πληθυσμού, από τις οποίες το 23% αφορούσαν το πρωτοβάθμιο επίπεδο πρόληψης, το 19% το δευτεροβάθμιο, το 23% το τριτοβάθμιο ενώ το 35% των μελετών σχετίζονταν με παραπάνω από ένα επίπεδο πρόληψης. Παρατηρήθηκε ότι συχνότερα χρησιμοποιήθηκε ο δείκτης αποτελεσματικότητας QALYs , σε ποσοστό 30% και ο δείκτης αποδοτικότητας ICER σε ποσοστό 44%. Το 81% των μελετών αποδείχθηκαν αποδοτικές. ΣΥΜΠΕΡΑΣΜΑΤΑ: Οι συστηματικές ανασκοπήσεις που εξετάστηκαν, στην πλειοψηφία τους ήταν αποδοτικές. Στο ίδιο πλαίσιο παρατηρήθηκε ότι ο ICER υπερτερεί των υπόλοιπων δεικτών .Ταυτοχρόνως, οι δείκτες αποδοτικότητας θα έπρεπε να αξιολογούνται λαμβάνοντας υπόψιν πολλούς παράγοντες (π.χ. χρόνος), ωστόσο οι περισσότεροι κρίνονται αποδοτικοί βάσει του κόστους. Οι μελλοντικές έρευνες χρειάζεται να εστιάσουν στην εκτίμηση της αποδοτικότητας με γνώμονα την ποιότητα ζωής των ανθρώπων.

description: We analyze the importance of flavor effects in models in which leptogenesis proceeds via the decay of Majorana electroweak triplets. We find that depending on the relative strengths of gauge and Yukawa reactions the $B-L$ asymmetry can be sizably enhanced, exceeding in some cases an order of magnitude level. We also discuss the impact that such effects can have for TeV-scale triplets showing that as long as the $B-L$ asymmetry is produced by the dynamics of the lightest such triplet they are negligible, but open the possibility for scenarios in which the asymmetry is generated above the TeV scale by heavier states, possibly surviving the TeV triplet related washouts. We investigate these cases and show how they can be disentangled at the LHC by using Majorana triplet collider observables and, in the case of minimal type III see-saw models even through lepton flavor violation observables.

description: Hemoglobinopathies, including α- and β-thalassemias and sickle cell disease, are among the most widely disseminated hereditary blood disorders worldwide. Bangladesh is considered a hotspot for hemoglobinopathies, and these diseases cause a significant health concern in the country. However, the country has a dearth of knowledge on the molecular etiology and carrier frequency of thalassemias, primarily due to a lack of diagnostic facilities, limited access to information, and the absence of efficient screening programs. This study sought to investigate the spectrum of mutations underlying hemoglobinopathies in Bangladesh. We developed a set of polymerase chain reaction (PCR)-based techniques to detect mutations in α- and β-globin genes. We recruited 63 index subjects with previously diagnosed thalassemia. Along with age- and sex-matched control subjects, we assessed several hematological and serum indices and genotyped them using our PCR-based methods. We identified that parental consanguinity was associated with the occurrence of these hemoglobinopathies. Our PCR-based genotyping assays identified 23 HBB genotypes, with the codons 41/42 (–TTCT) (HBB: c.126_129delCTTT) mutation leading the spectrum. We also observed the presence of cooccurring HBA conditions, of which the participants were not aware. All index participants in this study were on iron chelation therapies, yet we found they had very high serum ferritin (SF) levels, indicating inefficient management of the individuals undergoing such treatments. Overall, this study provides essential information on the hemoglobinopathy mutation spectrum in Bangladesh and highlights the need for nationwide screening programs and an integrated policy for diagnosing and managing individuals with hemoglobinopathies.
INTELLECTUAL PROPERTY&SECURITY INTERESTS: A US PERSPECTIVE

description: It is no secret that intellectual property can be a valuable business asset. As I.B.M.’s CEO, Samuel Palmisano, said, “ [I]ntellectual property is the crucial capital in a global knowledge economy.” 1 Expressing the same sentiment, a recently published article states that the “ driving force behind many of the mergers and acquisitions completed during the past decade has been the acquirer’s desire to obtain the target’s IP assets. Now, more than ever, the full financial potential of IP is being realized as an additional source of funding to facilitate research and development, acquisitions, and other commercial transactions.” 2 Despite this, a basic business transaction involving intellectual property, a secured loan, has many traps for the imprudent attorney or lender. The American Bar Association Task Force on Security Interests in Intellectual Property concluded that “ [t]he current state of the law governing security interests in intellectual property is unsatisfactory. There is uncertainty as to where and how to file, what constitute notice of a security interest, who has priority, and what properly is cover by a security interest.” 3 Reform of American laws has been long advocated in order to reduce uncertainty, but progress has been slow. As such, this article intends to inform foreign attorneys of the basic problems when securing a loan with intellectual property collateral under United States law.

description: We present VLT/FORS2 spectroscopy and GROND optical/near-IR photometry of the afterglow of the bright Fermi/LAT GRB 090926A. The spectrum shows prominent Lyman-alpha absorption with N_HI = 10^(21.73 +/- 0.07) cm^-2 and a multitude of metal lines at a common redshift of z=2.1062 +/- 0.0004, which we associate with the redshift of the GRB. The metallicity derived from SII is log(Z/Z_sun) ~ -1.9, one of the lowest values ever found in a GRB Damped Lyman-alpha (DLA) system. This confirms that the spread of metallicity in GRB-DLAs at z~2 is at least two orders of magnitude. We argue that this spread in metallicity does not require a similar range in abundances of the GRB progenitors, since the neutral interstellar medium probed by the DLA is expected to be at a significant distance from the explosion site. The hydrogen column density derived from Swift/XRT afterglow spectrum (assuming log(Z/Z_sun) ~ -1.9) is approx. 100 times higher than the N_HI obtained from the Lyman-alpha absorptions. This suggests either a large column density of ionized gas or a higher metallicity of the circum-burst medium compared to the gas traced by the DLA. We also discuss the afterglow light curve evolution and energetics. The absence of a clear jet-break like steeping until at least 21 days post-burst suggests a beaming corrected energy release of E_gamma>3.5x10^52erg, indicating that GRB090926A may have been one of the most energetic bursts ever detected.

Το έντονα ανταγωνιστικό περιβάλλον σε συνδυασμό με την ανθρωποκεντρική φύση του, οδήγησε με την πάροδο του χρόνου στη σταδιακή στρέβλωση, ακόμη και της φιλοσοφίας των ερευνητών. Από μία κουλτούρα συνεργασίας οδηγήθηκε σε ένα μικρόκοσμο έντονου ανταγωνισμού και οι ερευνητές μετατόπισαν το ενδιαφέρον τους από τη βελτίωση του έργου τους, στη βελτίωση της βαθμολογίας τους, στους συγκριτικούς δείκτες της αξιολόγησής τους. Από τις απαρχές του 2000 άρχισαν να εμφανίζονται οι πρώτοι δείκτες συγκριτικής αξιολόγησης και σύσσωμη η επιστημονική κοινότητα προσάρμοσε τις δραστηριότητές της με βάση αυτούς, παρατηρώντας την άνθιση φαινομένων όπως οι αυτοαναφορές και η πολυσυγγραφικότητα.

THE RECOVERY OF LOST PROFITS UNDER ARTICLE 74 OF THE U.N. CONVENTION ON THE INTERNATIONAL SALE OF GOODS
Creators: name: Schwartz, Damon
Publisher: name: Nordic Journal of Commercial Law
Year: 2006

description: The ability to obtain damages for losses suffered in the course of trade is a critical and necessary requirement for parties to be willing to engage in commerce. Without legal recourse for losses as a consequence of other parties’ nonperformance, the incentive to participate in trade is greatly diminished. International commerce is hampered to the extent that parties from different countries risk trading under foreign laws that might not offer comparable protection. The availability of relief for a breach of contract accords with economic efficiency in a free enterprise economy.1 The U.N. Convention on the International Sale of Goods (CISG) was created in 1980 to codify and harmonize a legal framework aimed at encouraging and facilitating international trade. An important feature of the CISG is Article 74, which provides a guide for the recovery of foreseeable losses, including lost profits, as a consequence of a party’s breach of contract.2 This right to obtain damages is a primary mechanism of the CISG remedial scheme.3 This paper will examine the recovery of lost profits under Article 74 CISG and discuss the practical issues that tribunals and parties face when evaluating a lost profit claim. Decisions concerning the recovery of lost profits under the CISG have been criticized as lacking uniformity due to problems in interpreting Article 74 CISG, differences in domestic evidentiary standards, use or nonuse of general principles of international law, arbitrator discretion, and difficulties in the actual calculation of lost profits.4 A discussion of these issues will attempt to shed light on the problems and determine if there is a lack of uniformity, and if so, what steps can be taken to increase the consistency of awards.

description: We study inelastic effects on the electronic current noise in molecular junctions, due to the coupling between transport electrons and vibrational degrees of freedom. Using a full counting statistics approach based on the generalized Keldysh Green's function technique, we calculate in an unified manner both the mean current and the zero-frequency current noise. For multilevel junctions with weak electron-phonon coupling, we give analytical formulas for the lowest order inelastic corrections to the noise in terms of universal temperature- and voltage-dependent functions and junction-dependent prefactors, which can be evaluated microscopically, e.g. with ab-initio methodologies. We identify distinct terms corresponding to the mean-field contribution to noise and to the vertex corrections, and we show that the latter contribute substantially to the inelastic noise. Finally, we illustrate our results by a simple model of two electronic levels which are mutually coupled by the electron-phonon interaction and show that the inelastic noise spectroscopy is a sensitive diagnostic tool.

description: Lubrication has been used to reduce the friction and wear of the mechanical components. Friction and wear are the reason behind most of the energy and material wastage in the industry. Petroleum-based oil is primarily used as the base lubricant, which is inherently toxic and has detrimental effects on the environment. Water is also used as the base lubricant for some applications, however, water itself is a poor lubricant. Biolubricants are used as the alternative to regular lubricants and are biodegradable, environmentally friendly, and come from a variety of resources. In this research, we have studied two aqueous biolubricants. In the first study, Cellulose Nanocrystals (CNCs) were used as additives to water, due to their superior properties such as renewability, biodegradability, and mechanical strength. The lubrication performance has been investigated using tribology. Tribological tests have been performed on a pin-on-disk tribometer in order to investigate the lubrication performance of this novel lubricant and more specific to evaluate its stability. The tribological properties of the CNC Suspensions in two regimes, semi-dilute and gel (grease), have been studied. Wear, stick-slip, and visualizations results showed that the CNC suspensions in the semi-dilute regime show better tribological properties than the suspensions in the gel regime. In the second study, the lubrication performance of an aqueous fucoidan solution as a biolubricant has been characterized. Fucoidan is used in various biomedical applications and is derived from brown algae (seaweed). This biocompatible lubricant provided by ARC Medical Devices Inc was studied as part of the product development stage so that it can be applied optimally during clinical operations while retaining its lubrication characteristics. Soft tribological tests were performed for the fucoidan solution as the novel lubricant and the Lactated Ringer’s solution as the control sample. Tribological tests were also performed on pig skin. In both experiments, the efficacy and improvement in tribological properties have been shown for fucoidan solutions compared to the control sample.

description: Black hole (BH) X-ray binaries (XRBs) are X-ray luminous binary systems comprising a BH accreting matter from a companion star. Understanding their origins sheds light on the still not well understood physics of BH formation. M33 X-7 hosts one of the most massive stellar-mass BH among all XRBs known to date, a 15.65 Msun BH orbiting a 70 Msun companion star in a 3.45 day orbit. The high masses of the two components and the tight orbit relative to the large H-rich stellar component challenge our understanding of the typically invoked BH-XRBs formation channels. The measured underluminosity of the optical component further complicates the picture. A solution to the evolutionary history of this system that can account for all its observed properties has yet to be presented, and here we propose the first scenario that is consistent with the complete set of current observational constraints. In our model, M33 X-7 started its life hosting a 85-99 Msun primary and a 28-32 Msun companion in a Keplerian orbit of 2.8-3.1 days. In order to form a BH of 15.65 Msun, the initially most massive component transferred part of its envelope to the companion star and lost the rest in a strong stellar wind. During this dynamically stable mass transfer phase the companion accreted matter, to become the presently underluminous 70 Msun star.

description: Unitary transformations and density matrices are central objects in quantum physics and various tasks require to introduce them in a parameterized form. In the present article we present a parameterization of the unitary group $\mathcal{U}(d)$ of arbitrary dimension $d$ which is constructed in a composite way. We show explicitly how any element of $\mathcal{U}(d)$ can be composed of matrix exponential functions of generalized anti-symmetric $σ$-matrices and one-dimensional projectors. The specific form makes it considerably easy to identify and discard redundant parameters in several cases. In this way, redundancy-free density matrices of arbitrary rank $k$ can be formulated. Our construction can also be used to derive an orthonormal basis of any $k$-dimensional subspaces of $\mathbb{C}^d$ with the minimal number of parameters. As an example it will be shown that this feature leads to a significant reduction of parameters in the case of investigating distillability of quantum states via lower bounds of an entanglement measure (the $m$-concurrence).

description: We show that microscopic calculations based on chiral effective field theory interactions constrain the properties of neutron-rich matter below nuclear densities to a much higher degree than is reflected in commonly used equations of state. Combined with observed neutron star masses, our results lead to a radius R = 9.7 - 13.9 km for a 1.4 M_{solar} star, where the theoretical range is due, in about equal amounts, to uncertainties in many-body forces and to the extrapolation to high densities.
