description: The main aim of this collection of essays is to challenge the general Western historical approach to the results of the Treaty of Versailles of 1919. The peace treaty (or, to be more accurate, a number of peace treaties) was signed between Allied and Central Powers and it established a new political order that was to govern European politics for the next twenty years. Essays published in this volume attempt to present a more complex picture of the post-World War I politics. As the authors argue, European peace after the Great War was governed not only by the Treaty of Versailles, but also by the Treaty of Riga signed in March 1921. In other words, Riga played as important a role in the East as Versailles did in the West. The book is not the first attempt to put the Treaty in a wider context. It is rather surprising that the editor of the volume does not mention Traktat ryski roku 1921 po 75 latach (1998), which is an earlier collection of essays edited by Mieczysław Wojciechowski.

description: We study the semiclassical dynamics of interacting electrons in a biased crystal lattice. A complex dynamical scenario emerges from the interplay between the Coulomb and the external electric fields. When the electrons are far apart, the Coulomb potential may be small compared to the external potential and the electrons oscillate with effective Bloch frequencies, determined by the local electric field. In the opposite case, nearby electrons either separate or form a bound pair, depending on the initial energy compared to the band width. The pair due to the Coulomb field is stable even in the absence of the external field.

description: For the truncated moment problem associated to a complex sequence $γ^{(2n)}=\{γ_{ij}\}_{i,j\in Z_{+},i+j \leq 2n}$ to have a representing measure $μ$, it is necessary for the moment matrix $M(n)$ to be positive semidefinite, and for the algebraic variety $\mathcal{V}_γ$ to satisfy $\operatorname{rank}\;M(n) \leq \;$ card$\;\mathcal{V}_γ$ as well as a consistency condition: the Riesz functional vanishes on every polynomial of degree at most $2n$ that vanishes on $\mathcal{V}_γ$. In previous work with L. Fialkow and M. Möller, the first-named author proved that for the extremal case (rank$\;M(n)=$ card$\;\mathcal{V}_γ$), positivity and consistency are sufficient for the existence of a representing measure. In this paper we solve the truncated moment problem for cubic column relations in $M(3)$ of the form $Z^{3}=itZ+u\bar{Z}$ ($u,t \in \mathbb{R}$); we do this by checking consistency. For $(u,t)$ in the open cone determined by $0 < \left|u\right| < t < 2 \left|u\right|$, we first prove that the algebraic variety has exactly $7$ points and $\operatorname{rank}\;M(3)=7$; we then apply the above mentioned result to obtain a concrete, computable, necessary and sufficient condition for the existence of a representing measure.

description: A new Multi-Carrier Differential Chaos Shift Keying (MC-DCSK) modulation is presented in this paper. The system endeavors to provide a good trade-off between robustness, energy efficiency and high data rate, while still being simple compared to conventional multi-carrier spread spectrum systems. This system can be seen as a parallel extension of the DCSK modulation where one chaotic reference sequence is transmitted over a predefined subcarrier frequency. Multiple modulated data streams are transmitted over the remaining subcarriers. This transmitter structure increases the spectral efficiency of the conventional DCSK system and uses less energy. The receiver design makes this system easy to implement where no radio frequency (RF) delay circuit is needed to demodulate received data. Various system design parameters are discussed throughout the paper, including the number of subcarriers, the spreading factor, and the transmitted energy. Once the design is explained, the bit error rate performance of the MC-DCSK system is computed and compared to the conventional DCSK system under an additive white Gaussian noise (AWGN) and Rayleigh channels. Simulation results confirm the advantages of this new hybrid design.

description: Musik ist ein Paradebeispiel für transnationale Wanderungen und Beziehungsgeflechte, zugleich aber auch für den Versuch, ‚Volk' und ‚Nation' kulturell zu imaginieren. Das Bonner Forschungsprojekt „Deutsche Musikkultur im östlichen Europa" arbeitet seit Jahren daran, vielfältige musikalische Wechselbeziehungen, Wahrnehmungen, nationale und regionale Aspekte zu untersuchen. Der vorliegende, von Erik Fischer herausgegebene Sammelband versteht sich dabei als eine Bestandsaufnahme, die in mehrere thematische Blöcke gegliedert ist. Den Auftakt bilden drei Aufsätze, in denen „Strukturen und Hierarchien" im Diskursfeld von Musik, ‚Volk', und ‚deutscher Kultur' zur Sprache kommen. Bettina Schlüter erinnert daran, dass der „Deutsche Bund Heimatschutz" 1904 vom Komponisten Ernst Rudorff gegründet wurde – ein gutes Beispiel für die vielfältigen Rollen, die Musik zugesprochen wurde. Einerseits übernahm sie bei der Kunstmusik „legitimatorische Funktionen im Rahmen eines kulturell-hegemonialen, sozialdarwinistisch überformten Großmachtanspruchs" und sollte andererseits auf volks- bzw. kirchenmusikalischer Ebene der Festigung und „Zirkulation national-ethnisch codierter Zeichen" (S. 10-11) dienen. Gunther Hirschfelder und Lars Winterberg führen diese Gedanken aus volkskundlicher Perspektive weiter aus, während Dirk Kohlhaas anhand des Jahrgangs 1926 der im siebenbürgischen Herrmannstadt erscheinenden Zeitschrift „Ostland. Vom geistigen Leben der Auslandsdeutschen" den Topos von Deutschland, dem „Land der Musik", analysiert. Er kommt zu dem Ergebnis , dass die Autoren – wie auch viele ihrer deutschen Zeitgenossen – von einer Höherwertigkeit der deutschen Musikkultur ausgingen und einen gleichwertigen Austausch mit den umgebenden Musikkulturen praktisch ausschlossen.

description: It is no new insight that history is more than the dealings of presidents, kings and prime ministers. Nevertheless, the history of the East-West conflict is still very often a story of high level negotiations and government considerations. Although the interest in the impact that the division of Europe and the enforcement of communism in Eastern Europe has had on society in East and West has gained ground, this kind of research seldom encompasses a view of both sides of the conflict. The importance of the articles in the book Entangled Protest lies in doing exactly this – telling the story of the contact between East and West 'from below'.

description: Η παρούσα ερευνητική εργασία επιχειρεί τη διερεύνηση των επεμβάσεων στα αστικά ρέματα και στις παραρεμάτιες περιοχές τους ως πράσινες υποδομές του αστικού τοπίου στη διεθνή πραγματικότητα. Κύριο αντικείμενο της έρευνας αποτελεί το ρέμα ως όριο αλλά και ως συνδετικό στοιχείο του αστικού ιστού.

Θεωρώντας τα αστικά ρέματα ως χώρο επέμβασης του αστικού σχεδιασμού, επιχειρείται η σύνδεση του με το τοπίο, το φυσικό περιβάλλον και την πόλη. Γίνεται έτσι αναφορά στις πρακτικές της Τοπιακής Πολεοδομίας, η οποία εξετάζει το όριο ανάμεσα στην πόλη (πολιτισμός)  και τη φύση ως αστικό τοπίο.

Στην συνέχεια, εξετάζεται το πράσινο στον αστικό ιστό ως προς την λειτουργία του και την σημαντικότητα του. Παρουσιάζεται το ρέμα ως πράσινη υποδομή και γίνεται αναφορά στην λειτουργία και στα οφέλη που προσφέρει στην πόλη.

Επίσης αναλύονται οι προσπάθειες για περιβαλλοντική κινητοποίηση και παρουσιάζονται οι πρακτικές της αποκατάστασης και αποκάλυψης ρεμάτων, τα είδη τους και οι λόγοι που οδήγησαν στην επέμβαση τους.

Τέλος, γίνεται αναλυτική περιγραφή οκτώ συγκεκριμένων παραδειγμάτων κατανεμημένων σε δύο κατηγορίες, τις επεμβάσεις για την δημιουργία αστικού πάρκου και τις επεμβάσεις για την δημιουργία γραμμικού υπαίθριου χώρου. Η περιγραφή αυτή περιλαμβάνει σύντομη ιστορική αναφορά, τους λόγους και τις πολιτικές επέμβασης, τις εργασίες αποκατάστασης ή αποκάλυψης, την αστική διαμόρφωση και αρχιτεκτονική ανάλυση και τέλος τα αποτελέσματα της επέμβασης ως προς το φυσικό το πολιτισμικό και το οικονομικό περιβάλλον της πόλης.

description: The present study attempts to investigate the urban stream restoration and daylighting technics as a green infrastructure of urban landscape internationally. The main object of this research is the stream as a limit but also as a connection element of the urban web.

Considering the urban streams as an intervention area for urban planning, it is attempted to establish connections with the landscape , the natural environment and the city. Therefore, a reference is made to the theory of landscape urbanism that investigates the limit between civic and nature as a part of urban landscape.

Furthermore, this study focuses on the meaning of urban green spaces and their importance. They are presented as part of green infrastructure while their benefits and urban functions in the city are examined.

In addition, a reference is made to the recovery efforts of natural environment as part of the studies of natural stream restoration and stream daylighting.

Finally, there is a detailed description of eight specific examples, which are categorized in two sections, the creation of an urban park and the creation of urban green corridors. This description includes a brief historical reference of the stream, the reasons to restore it and the political strategies, the construction, the methological framework, the architectural analysis and the results in the cultural, economic and natural environment.

description: We investigate theoretically systems of ions in segmented linear Paul traps for the quantum simulation of quantum spin models with tunable interactions. The scheme is entirely general and can be applied to the realization of arbitrary spin-spin interactions. As a specific application we discuss in detail the quantum simulation of models that exhibit long-distance entanglement in the ground state. We show how tailoring of the axial trapping potential allows for generating spin-spin coupling patterns that are suitable to create long-distance entanglement. We discuss how suitable sequences of microwave pulses can implement Trotter expansions and realize various kinds of effective spin-spin interactions. The corresponding Hamiltonians can be varied on adjustable time scales, thereby allowing the controlled adiabatic preparation of their ground states.

Green Reference, A New Hyperspectral Image Referencing Technique

description: The Leafspec portable imaging device had provided a reliable low-cost hyperspectral image acquisition solution to a wide range of users. The Leafspec implemented a enclosed imaging environment and a build-in halogen light source, which eliminated the influence of ambient light. However, a uniform light source was hard to achieve due to dimension and power restrains. White Reference, in many cases refer to an image of a uniform white material such as a Teflon board. White Referencing is a widely used calibration technique in the effort of minimizing noises in an image, including ones that are induced by the light source. However, an abnormal spatial distribution was found remained in images collected by Leafspec even after performing White Referencing technique. In hypothesis, the huge spectral difference between Teflon board and leaves caused this issue. Following this assumption, this article proposed to use a uniform section of soybean leaf to create a Green Reference for calibrating hyperspectral images. In our experiment, 20 green reference samples were collected by imaging a 15 𝑚𝑚 × 15 𝑚𝑚 most uniform section from soybean leaf along a 100 𝑚𝑚 imaging window with a 5 𝑚𝑚 increment.

description: We study the fundamental challenge of exhibiting explicit functions that have small correlation with low-degree polynomials over $\mathbb{F}_{2}$. Our main contributions include: 1. In STOC 2020, CHHLZ introduced a new technique to prove correlation bounds. Using their technique they established new correlation bounds for low-degree polynomials. They conjectured that their technique generalizes to higher degree polynomials as well. We give a counterexample to their conjecture, in fact ruling out weaker parameters and showing what they prove is essentially the best possible. 2. We propose a new approach for proving correlation bounds with the central "mod functions", consisting of two steps: (I) the polynomials that maximize correlation are symmetric and (II) symmetric polynomials have small correlation. Contrary to related results in the literature, we conjecture that (I) is true. We argue this approach is not affected by existing "barrier results". 3. We prove our conjecture for quadratic polynomials. Specifically, we determine the maximum possible correlation between quadratic polynomials modulo 2 and the functions $(x_{1},\dots,x_{n})\to z^{\sum x_{i}}$ for any $z$ on the complex unit circle; and show that it is achieved by symmetric polynomials. To obtain our results we develop a new proof technique: we express correlation in terms of directional derivatives and analyze it by slowly restricting the direction. 4. We make partial progress on the conjecture for cubic polynomials, in particular proving tight correlation bounds for cubic polynomials whose degree-3 part is symmetric.

description: The volume edited by Kerstin Jacobsson and Steven Saxonberg contains a collection of studies about the specifics of the non-governmental organizations (NGOs) and selected social movements in post-communist countries in Europe. The main aim of the book is to re-examine the notion of NGO-ization, which describes non-profit organizations and civic charities as structured, professional, and dependent on grants. The NGO-ization theory reveals the mechanism of the negative influence of donors on the development of NGOs. After regular financial support the sponsored NGOs usually change their modus operandi, and eventually focus much more on the mining of funds than on social work. On the other hand, they work only when they have the financial resources. This means that NGOs actually become quite addicted to the system of grants, which changes their focus from helping people to fundraising. The idea of NGO-ization is commented on in almost every chapter of the book from various perspectives.

description: Στην παρούσα εργασία εξετάζεται το φαινόμενο της έξαρσης της ναοδομίας στην ύπαιθρο του νομού Χανίων κατά τον 19ο αιώνα, λόγω συγκεκριμένων ιστορικών και κοινωνικών διεργασιών.
	Η άνθιση, αυτή, της ναοδομίας έθεσε ορισμένους προβληματισμούς αναφορικά με την αρχιτεκτονική των ναών αυτών καθώς και τα μορφολογικά και τα επιμέρους χαρακτηριστικά τους.
	Συγκεκριμένα διαπιστώθηκε, μέσα από την αντιπαραβολή παραδειγμάτων, ότι η ναοδομία της κρητικής υπαίθρου φέρει πολλά κοινά ή καλύτερα, παρεμφερή χαρακτηριστικά με την αρχιτεκτονική της ύστερης περιόδου της βενετοκρατίας στην Κρήτη, γνωστής περισσότερο σαν Κρητική Αναγέννηση.
	Παραδείγματα από την τυπολογία των ναών καθώς και από την διακόσμηση των ανοιγμάτων, θυρών και παραθύρων συγκρίθηκαν με αντίστοιχα παραδείγματα του 16ου - 17ου αιώνα. Από την σύγκριση αυτή έγινε κατανοητό ότι οι επιδράσεις της εποχής εκείνης συνεχίζουν να ενσωματώνονται και στα έργα του 19ου αιώνα μέσα από γόνιμη προσαρμογή στα νέα πρότυπα. Σε αυτό συνέβαλε και η, σε πολλές περιπτώσεις, οικοδόμηση νέων εκκλησιών στην θέση παλαιών που κατεδαφίζονταν επί τούτου. Έγινε κατανοητό ότι πλέον οι φορείς της ανοικοδόμησης ήταν οι ίδιοι οι κάτοικοι των χωριών ενώ ρόλο έπαιζαν και οι τεχνίτες και αρχιτέκτονες που παρείχαν την εργασία τους στα χωριά της περιοχής. Παράλληλα μελετήθηκε το είδος των υλικών καθώς και το κόστος των εργασιών ως συντελεστές για την διαμόρφωση των κτισμάτων. Τέλος αποτιμήθηκε η σημερινή κατάστασή τους και η προοπτικές για το μέλλον των ναών αυτών.

With the assignment of left-handed quarks and leptons to S_4-doublet, SUSY flavor problem is softened. As the extra Higgs bosons are neutrinophilic, baryon number asymmetry in the universe is realized by leptogenesis without causing gravitino overproduction. We find that the allowed region for the lightest chargino mass is given by 100-140 GeV, if the dark matter is a singlino dominated neutralino whose mass is about 36 GeV.

They include David Tompkins, who published on the subject of music making and reception in Poland and the GDR in the Stalinist era and Mary Neuburger, co-editor of a volume about consumption in Cold War Eastern Europe.[1] The essays contained in this compilation reflect the diversity of their authors' interests and expertise and address a wide array of historical practices in countries of the Soviet bloc that enabled their citizens to create spaces of relative freedom within the confines of the regimes in which they lived. Interestingly enough, many of the authors point out how the regimes themselves, knowingly or inadvertently, provided these opportunities and tried to encourage or control them, depending on the local circumstances and the time period.

description: Can a Bell test with no detection loophole be demonstrated for multi-photon entangled states of light within the current technology? We examine the possibility of a postselection-free CHSH-Bell inequality test wih an unsymmetrical polarization singlet. To that end we employ a preselection procedure which is performed prior to the test. It allows using imperfect (coarse-grained) binary photodetection in the test. We show an example of preselection scheme which improves violation of the CHSH inequality with the micro-macro polarization singlet produced by the optimal quantum cloning. The preselection is realized by a quantum filter which is believed to be not useful for this purpose.

description: In the last decades, an ever-growing number of studies are focusing on the extreme weather conditions related to the climate change. Some of them are based on multifractal approaches, such as the Multifractal Detrended Fluctuation Analysis (MF-DFA), which has been used in this work. Daily diurnal temperature range (DTR), maximum, minimum and mean temperature from five coastal and five mainland stations in Spain have been analyzed. For comparison, two periods of 30 years have been considered: 1960-1989 and 1990-2019. By using the MF-DFA method, generalized Hurst exponents and multifractal spectra have been obtained. Outcomes corroborate that all these temperature variables have multifractal nature and show changes in multifractal properties between both periods. Also, Hurst exponents values indicate that all time series exhibit long-range correlations and a stationary behavior. Coastal locations exhibit in general wider spectra for minimum and mean temperature than for maximum and DTR, in both periods. On the contrary, the mainland ones do not show this pattern. Also, width from multifractal spectra of these two variables (minimum and mean temperature) is shortened in the last period in almost every case. To authors' mind, changes in multifractal features might be related to the climate change experienced in the studied region. Furthermore, reduction of spectra width for minimum and mean temperature implies a decrease of the complexity of these temperature variables between both studied periods. Finally, the wider spectra found in coastal stations might be useful as a discriminator element to improve climate models.

description: Doubly non-negative matrices arise naturally in many setting including Markov random fields (positively banded graphical models) and in the convergence analysis of Markov chains. In this short note, we settle a recent conjecture by C.R. Johnson et al. [Linear Algebra Appl. 435 (2011)] by proving that the critical exponent beyond which all continuous conventional powers of $n$-by-$n$ doubly nonnegative matrices are doubly nonnegative is exactly $n-2$. We show that the conjecture follows immediately by applying a general characterization from the literature. We prove a stronger form of the conjecture by classifying all powers preserving doubly nonnegative matrices, and proceed to generalize the conjecture for broad classes of functions. We also provide different approaches for settling the original conjecture.

description: We propose a fast and efficient approach for solving the Bogoliubov-de Gennes (BdG) equations in superconductivity, with a numerical matrix-size reduction procedure proposed by Sakurai and Sugiura [J. Comput. Appl. Math. 159, 119 (2003)]. The resultant small-size Hamiltonian contains the information of the original BdG Hamiltonian in a given energy domain. In other words, the present approach leads to a numerical construction of a low-energy effective theory in superconductivity. The combination with the polynomial expansion method allows a self-consistent calculation of the BdG equations. Through numerical calculations of quasi-particle excitations in a vortex lattice, thermal conductivity, and nuclear magnetic relaxation rate, we show that our approach is suitable for evaluating physical quantities in a large-size superconductor and a nano-scale superconducting device, with the mean-field superconducting theory.

title: Tool for optimized design of integrated RF CMOS low noise amplifiers

description: The demand for larger bandwidth in wireless communications, motivates the RF circuit designers to advance to higher frequencies in order to serve the rapidly growing market. CMOS technology has dominated in the design of radio frequency and analog integrated circuits. Using devices in the nanometer regime, provides the possibility for greater operation frequencies and ultimately faster data rates.  Additionally, RF circuit design is increasingly taking advantage of the aggressive scaling of submicrometer CMOS technologies that make possible the integration of complete tele-communication systems in a single chip (SoC). Low noise amplifiers (LNA) are one of the most important blocks of any telecommunication system. Their importance lies on the fact that they impact the noise performance more than any of the other blocks in the receiver chain. The main purpose of the low noise amplifier is to increase the power of the attenuated input signal, while at the same time minimizing the noise added to the chain by the circuit itself. In the RF design procedure, a designer faces the problem of trade-offs in quantities like consumption, gain, linearity etc. The purpose of this thesis is the introduction of a theoretical model that defines the optimum operation of a LNA (figure-of-merit) and afterwards the introduction of a design methodology that approaches the theoretical response. The thesis also proposes the integration of a genetic algorithm in the design sequence, that finds actual optimum solutions using the procedures of natural selection, reproduction and mutation. Finally, the efficiency of the equation model and genetic algorithm combination is showcased with the design of an optimum 5 GHz common source LNA. The optimal LNA design is obtained in the region of moderate inversion, according to both the analytical model and the optimization procedure. Furthermore, the other LNA topologies such as cascode LNA and common gate LNA are also evaluated. This work provides valuable insight into the design trade-offs of the different LNA topologies.

description: Τα τελευταία χρόνια η σπουδαιότητα της τηλεϊατρικής κίνησης έχει αυξηθεί σημαντικά. Εξ’ αιτίας του ότι μεταφέρει κρίσιμες πληροφορίες που αφορούν την κατάσταση της υγείας των ασθενών, η άμεση, ταχεία και χωρίς σφάλματα μετάδοση της τηλεϊατρικής κίνησης είναι θεμελιώδους σημασίας.
Στην εργασία μας οι αρχικοί στόχοι που θέσαμε ήταν να βρούμε τρόπους ώστε οι χρήστες τηλεϊατρικής και κανονικής κίνησης να έχουν την καλύτερη δυνατή εξυπηρέτηση με κριτήρια τις μικρότερες δυνατές απώλειες πακέτων (να γίνεται η μέγιστη δυνατή εκμετάλλευση του bandwidth), την καλύτερη δυνατή ικανοποίηση των απαιτήσεων QoS τους και τη μέγιστη δυνατή δικαιοσύνη.
Για να τα πετύχουμε αυτά, αρχικά προσαρμόσαμε ένα ήδη υπάρχον πρωτόκολλο ελέγχου πολλαπλής πρόσβασης [Multiple Access Control or Media Access Control (MAC) protocol] ώστε να είναι δυνατή η ταυτόχρονη μετάδοση κανονικής και τηλεϊατρικής κίνησης.
Κάναμε προσαρμογή, στο πρωτόκολλο μας, επτά αλγορίθμων χρονοπρογραμματισμού (Scheduling Algorithms) που υπήρχαν στη βιβλιογραφία για να εκτιμήσουμε την απόδοση τους.
Για να κάνουμε καλύτερη εκτίμηση της απόδοσης προσθέσαμε τρεις επιπλέον, του ήδη υπάρχοντος, δείκτες δικαιοσύνης τους οποίους επεκτείναμε σε περισσότερες μετρήσεις.
Λόγω της εμπειρίας που αποκτήσαμε αποφασίσαμε να δημιουργήσουμε ένα δικό μας αλγόριθμο χρονοπρογραμματισμού επιδιώκοντας να πετυχαίνει την καλύτερη εξυπηρέτηση.
Θεωρούμε πως πετύχαμε τις επιδιώξεις μας σε αρκετά ικανοποιητικό βαθμό γιατί ο αλγόριθμος μας, έδωσε καλά αποτελέσματα.
Πιστεύουμε πως σημαντική συνεισφορά της εργασίας μας είναι ότι μας οδήγησε σε χρήσιμα συμπεράσματα που αφορούν γενικότερα τους αλγορίθμους χρονοπρογραμματισμού για χρήση τους σε παρόμοιου τύπου MAC πρωτόκολλα.

description: Multinucleon transfer processes in heavy-ion reactions at energies slightly above the Coulomb barrier are investigated in a fully microscopic framework of the time-dependent Hartree-Fock (TDHF) theory. Transfer probabilities are calculated from the TDHF wave function after collision using the projection operator method which has recently been proposed by Simenel (C. Simenel, Phys. Rev. Lett. 105, 192701 (2010)). We show results of the TDHF calculations for transfer cross sections of the reactions of $^{40,48}$Ca+$^{124}$Sn at $E_{lab}=$ 170, 174 MeV, $^{40}$Ca+$^{208}$Pb at $E_{lab}=$ 235, 249 MeV, and $^{58}$Ni+$^{208}$Pb at $E_{lab}=$ 328.4 MeV, for which measurements are available. We find the transfer processes show different behaviors depending on the $N/Z$ ratios of the projectile and the target, and the product of the charge numbers, $Z_P Z_T$. When the projectile and the target have different $N/Z$ ratios, fast transfer processes of a few nucleons towards the charge equilibrium of the initial system occur in reactions at large impact parameters. As the impact parameter decreases, a neck formation is responsible for the transfer. A number of nucleons are transferred by the neck breaking when two nuclei dissociate, leading to transfers of protons and neutrons in the same direction. Comparing cross sections by theory and measurements, we find the TDHF theory describes the transfer cross sections of a few nucleons reasonably. As the number of transferred nucleons increases, the agreement becomes less accurate. The TDHF calculation overestimates transfer cross sections accompanying a large number of neutrons when more than one proton are transferred. Comparing our results with those by other theories, we find the TDHF calculations give qualitatively similar results to those of direct reaction models such as GRAZING and Complex WKB.

Universal mass limits on gluino and third-generation squarks in the context of Natural-like SUSY spectra

description: In this paper, we present results based on a combination of four inclusive topology searches for supersymmetry (SUSY) from the CMS experiment, and use this to determine universal mass limits on gluino and third-generation squarks in the context of Natural-like SUSY spectra. The class of Natural-like SUSY spectra considered follows the typical Natural SUSY model made up of a gluino, third-generation squarks, and higgsino sparticles, but is extended to more complex spectra containing sleptons. We show that the limits obtained from the combination of inclusive topology searches are far more stable than those from individual searches, with respect to the assumed underlying complexity of the spectra. Hence, these limits can be considered as universal mass limits on gluino and third-generation squarks, defined in the context of this broad class of Natural-like SUSY spectra. Furthermore, we present our results using a simple colour scheme that allows a straightforward interpretation of any Natural-like SUSY spectrum with our limits. Complementing the final results of the 2011 searches based on 5 $\textrm{fb}^{-1}$ of integrated luminosity, with the first published results from the 2012 searches using approximately 11 $\textrm{fb}^{-1}$, we find that gluinos with a mass of $m_{\tilde{g}}\approx$ 1050 GeV and third-generation top and bottom squarks with masses of $m_{\tilde{3G}}\approx$ 575 GeV are excluded for low masses of the lightest SUSY particle (LSP). We also establish a prediction of how these limits might evolve when the full 2012 data set is analysed, with both the CMS and ATLAS experiments combined. The importance of combining relevant inclusive topology searches, in order to make the most universal interpretations possible, is a general recommendation for future experimental searches at the LHC.

description: Excerpts from the report: The Agriculture and Consumer Protection Act of 1973 directed the Secretary of Agriculture to conduct a cost of production study of wheat, feed grains, cotton, and dairy commodities and to annually update the cost estimates. The Commodity Economics Division, Economic Research Service conducted the study, aided by an advisory committee comprised of representatives of the general farm organizations, commodity organizations, land grant colleges, agricultural economic associations, and the Federal Extension Service. This report provides a summary of results of the study for crops in 1974. The objectives of the study were to: (1) establish benchmark estimates of national average cost of production for wheat, feed grains, cotton, and milk as required by law; (2) establish production cost estimates for soybeans, peanuts, and flaxseed--important competing crops in certain subregions; (3) measure the variability within and among the production subregions in practices, inputs, outputs, prices, and costs; and (4) provide a data base for annual updates of the estimates and for research purposes.

description: Denote by $[0,ω_1)$ the set of countable ordinals, equipped with the order topology, let $L_0$ be the disjoint union of the compact ordinal intervals $[0,α]$ for $α$ countable, and consider the Banach spaces $C_0[0,ω_1)$ and $C_0(L_0)$ consisting of all scalar-valued, continuous functions which are defined on the locally compact Hausdorff spaces $[0,ω_1)$ and $L_0$, respectively, and which vanish eventually. Our main result states that a bounded operator $T$ between any pair of these two Banach spaces fixes a copy of $C_0(L_0)$ if and only if the identity operator on $C_0(L_0)$ factors through $T$, if and only if the Szlenk index of $T$ is uncountable. This implies that the set $\mathscr{S}_{C_0(L_0)}(C_0(L_0))$ of $C_0(L_0)$-strictly singular operators on $C_0(L_0)$ is the unique maximal ideal of the Banach algebra $\mathscr{B}(C_0(L_0))$ of all bounded operators on $C_0(L_0)$, and that $\mathscr{S}_{C_0(L_0)}(C_0[0,ω_1))$ is the second-largest proper ideal of $\mathscr{B}(C_0[0,ω_1))$. Moreover, it follows that the Banach space $C_0(L_0)$ is primary and complementably homogeneous.
