description: The preparation of alkyne-modified ansamitocins by mutasynthetic supplementation of Actinosynnema pretiosum mutants with alkyne-substituted aminobenzoic acids is described. This modification paved the way to introduce a thiol linker by Huisgen-type cycloaddition which can principally be utilized to create tumor targeting conjugates. In bioactivity tests, only those new ansamitocin derivatives showed strong antiproliferative activity that bear an ester side chain at C-3.
Erfolgreiche Bildungsstrategien in Tansania am Beispiel des Hochschulzugangs

description: Der Zugang zu Hochschulbildung ist in Tansania sehr stark ausgebaut worden. Insbesondere die Quote von Studierenden mit einem niedrigen sozioökonomischen Status soll so erhöht werden. Der Bildungsweg gestaltet sich jedoch speziell im tansanischen Kontext aufgrund zahlreicher Bildungsbarrieren problematisch. Hier sind insbesondere schlecht ausgebildete Lehrkräfte, eine unzureichende schulische Infrastruktur sowie überfüllte Klassenräume zu nennen. Es soll nun untersucht werden, wie der Hochschulzugang trotz der Bildungshürden gelingen kann. Überdies soll erforscht werden, welchen Stellenwert familiäre Unterstützung sowie individuelle Bewältigungsstrategien einnehmen. In diesem Zusammenhang sollen auch die Unterschiede in Hinblick auf die Schichtzugehörigkeit analysiert werden. Zur Analyse der familiären Ebene wird das Konzept der Kapitaltheorie von Bourdieu verwendet. Um die individuelle Dimension der Überwindungsstrategien zu erfassen, wird das Modell der Zielorientierung von Dweck genutzt. Im Zentrum der Arbeit stehen dabei die Bildungsverläufe der Studierenden. Diese werden definiert als individueller Verlauf des Bildungsweges, der durch die unterschiedliche Ausstattung mit ökonomischen sowie kulturellen Ressourcen geprägt ist. Zur Bearbeitung der Fragestellung werden Studierende mithilfe von halb-standardisierten Interviews befragt. Die Bildungswege werden dann mit der qualitativen Inhaltsanalyse von Mayring ausgewertet. Im Rahmen einer Typenbildung zeigt sich, dass für Studierende mit einem hohen sozioökonomischen Status das familiäre Netz von großer Bedeutung war. Das familiäre Kapital trägt entscheidend zu dem Bildungserfolg bei. Für Personen aus ärmeren Familien war hingegen die selbstständige Überwindung der Bildungsbarrieren von erheblicher Wichtigkeit. Speziell ein hoher Grad von Selbstständigkeit sowie Aufstiegsorientierung waren hier zentral.
title: Tobacco and Its Role in the Life of the Confederacy
Creators: name: Smith, D. T.
Publisher: name: Old Dominion University Libraries
Year: 1993

description: This study examines the role that tobacco played in influencing Confederate policy during the American Civil War. Surprisingly, very little research has been done on this subject; historians have virtually ignored the influence of tobacco upon Southern economic interests between 1850 and 1870.

The southern tobacco-producing states grew 439,183,561 pounds of raw tobacco in 1860. Southern manufactured tobacco was worth $21,820,535 in 1860, and along with other agricultural products, especially cotton, played an important economic, political, and diplomatic role in the life of the Confederacy. The tobacco industry represented a very strong interest group in the Upper South during the Civil War.

After the war, tobacco emerged again as the principal cash crop of the Upper South, as consumption became a national pastime.
title: John Bankhead Magruder and the Defense of the Virginia Peninsula, 1861-1862
Creators: name: Riedel Jr., Leonard W.
Publisher: name: Old Dominion University Libraries
Year: 1991

description: The viability of the Confederacy depended on its ability to organize a government and military defense force. Two early concerns were the operation of Gosport Naval Shipyard and protection of the Confederate capital at Richmond. Poised between them was Fortress Monroe.

With undisputed Union mastery of the Chesapeake Bay, Fortress Monroe was a constant reminder of the tentative security of these critical points. The man chosen to protect the Peninsula was Virginian, John Bankhead Magruder. Less than one year later, his efforts were denigrated by Commanding General Joseph E. Johnston who wanted to pursue his own strategic plan.

Under constant stress, Magruder performed with alacrity. Although the Peninsula was evacuated in May 1862, Magruder did an admirable job of defense. Magruder's place in history has been discolored by perceived battlefield failures at Savage's Station and Malvern Hill. These are an unfortunate footnote to an otherwise solid military career.

In contrast to other recently proposed algorithms which only give approximate tree projections for a given sparsity, our algorithm is guaranteed to calculate the projection exactly. We also prove that our algorithm has O(Nk) complexity, where N is the signal dimension and k is the sparsity of the tree approximation.

Publisher: name: Old Dominion University Libraries
Year: 1987

description: At the beginning of the nineteenth century Britain's public records were scattered among more than fifty depositories which were overcrowded, unorganized, neglected, and ill-suited to record preservation. The British government was not sympathetic to the condition or the importance of the records. How then did the British government become involved in creating the Public Record Office and building its first fireproof repository? This study takes the form of a chronology based extensively on the records of the Public Record Office, the Office of Works, and the British Sessional Papers.

Although the creation of the Public Record Office was part of a larger preservation movement in the nineteenth century, in fact, it was the result of the efforts of a few devoted individuals. The design and construction of Britain's central archive was the result of the efforts of one architect--James Pennethorne.

title: U.S.S. New Ironsides: The Seagoing Ironclad in the Union Navy
Creators: name: Roberts, William Howard
Publisher: name: Old Dominion University Libraries
Year: 1992

description: Of the ironclads completed by the Union during the Civil War, only the U.S.S. New Ironsides was a seagoing, high-freeboard design. Her seagoing qualities and heavy battery made her uniquely valuable to the Union in combat. Although New Ironsides was highly successful and her high-freeboard design squarely in the European mainstream, she represented the last of her direct line in the U.S. Navy. The lessons learned from her construction and wartime service, which should have provided invaluable instruction for U.S. designers, were not followed up. By failing to develop the seagoing ironclad the United States forfeited the advantages it might have gained over European navies from its extensive combat experience. The Navy was unable to convince Congress that money for ironclads would be well spent, and the U.S. Navy's best opportunity to build a seagoing ironclad fleet was lost for a generation.

description: A toroidal, quasi-linear model is proposed to study the penetration dynamics of the resonant magnetic perturbation (RMP) field into the plasma. The model couples the linear, fluid plasma response to a toroidal momentum balance equation, which includes torques induced by both fluid electromagnetic force and by (kinetic) neoclassical toroidal viscous force. The numerical results for a test toroidal equilibrium quantify the effects of various physical parameters on the field penetration and on the plasma rotation braking. The neoclassical toroidal viscous torque plays a dominant role in certain region of the plasma, for the RMP penetration problem considered in this work.

Electronic Born-Oppenheimer Approximation in Nuclear-Electronic Orbital Dynamics
Creators: name: Li, Tao E.

Publisher: name: arXiv
Year: 2023
Subjects: subject: Chemical Physics (physics.chem-ph)
subject: FOS: Physical sciences

description: Within the nuclear-electronic orbital (NEO) framework, the real-time NEO time-dependent density functional theory (RT-NEO-TDDFT) approach enables the simulation of coupled electronic-nuclear dynamics. In this approach, the electrons and quantum nuclei are propagated in time on the same footing. A relatively small time step is required to propagate the much faster electronic dynamics, thereby prohibiting the simulation of long-time nuclear quantum dynamics. Herein, the electronic Born--Oppenheimer (BO) approximation within the NEO framework is presented. In this approach, the electronic density is quenched to the ground state at each time step, and the real-time nuclear quantum dynamics is propagated on an instantaneous electronic ground state defined by both the classical nuclear geometry and the nonequilibrium quantum nuclear density. Because the electronic dynamics is no longer propagated, this approximation enables the use of an order-of-magnitude larger time step, thus greatly reducing the computational cost. Moreover, invoking the electronic BO approximation also fixes the unphysical asymmetric Rabi splitting observed in previous semiclassical RT-NEO-TDDFT simulations of vibrational polaritons even for small Rabi splitting, instead yielding a stable, symmetric Rabi splitting. For intramolecular proton transfer in malonaldehyde, both RT-NEO-Ehrenfest dynamics and its BO counterpart can describe proton delocalization during the real-time nuclear quantum dynamics. Thus, the BO RT-NEO approach provides the foundation for a wide range of chemical and biological applications.

title: Troubled minds and scarred bodies: a grounded theory study of adolescent self-harm
Creators: name: Nice, Terence
Publisher: name: University of Kent
Year: 2023

description: Adolescent self-harm is an international and national issue that is positively related to adolescent suicide. It has a major impact upon the lives of young people and their families and represents a significant drain upon the economic and clinical resources of the National Health Service. The research objective of this project was to investigate what might be happening in the minds of young people who self-harm. The project was designed to capture the micro-processes of adolescent self-harm in order to identify significant constructs for the purpose of theory generation and clinical application. It is a grounded theory study of 12 adolescents aged 13-16 years old (9 females and 3 males) presenting to hospital after an episode of self-harm. A single interview was conducted after episodes of self-harm and analysed using a narrative and construct based approach.

description: In this article, we study the long-time behavior of solutions of the two-dimensional fluid-rigid disk problem. The motion of the fluid is modeled by the two-dimensional Navier-Stokes equations, and the disk moves under the influence of the forces exerted by the viscous fluid. We first derive $L^p$-$L^q$ decay estimates for the linearized equations and compute the first term in the asymptotic expansion of the solutions of the linearized equations. We then apply these computations to derive time-decay estimates for the solutions to the full Navier-Stokes fluid-rigid disk system.
Influence of quark masses on the QCD phase diagram in the presence of a magnetic field

description: The most recent lattice results on the QCD phase diagram in the presence of a strong magnetic field strongly disagree with results from previous lattice simulations and several model calculations. The most remarkable difference is the qualitative behavior of the critical temperature as a function of the magnetic field intensity, which in later results are shown to decrease in opposition to what was found previously. According to the authors, such a discrepancy in lattice simulations could be due to different lattice spacing, or different number of flavors and quark masses. We investigate the influence of quark masses on the Polyakov- Quark-Meson model and show that, although quantitatively the results are sensitive to those parameters, the qualitative behavior remains the same.

Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)
subject: FOS: Physical sciences

description: Emission from astronomical jets extend over the entire spectral band: from radio to the TeV gamma-rays. This implies that various radiative processes are taking place in different regions along jets. Understanding the origin of the emission is crucial in understanding the physical conditions inside jets, as well as basic physical questions such as jet launching mechanism, particle acceleration and jet composition. In this chapter I discuss various radiative mechanisms, focusing on jets in active galactic nuclei (AGN) and X-ray binaries (XRB) environment. I discuss various models in use in interpreting the data, and the insights they provide.

Year: 1984

description: This is a study of material culture in Princess Anne County, Virginia, from 1691 to 1823, based on court records. These documents allow the historian to determine the economic worth of a group of individuals, analyze the types of people comprising this group, categorize the types and quantities of possessions owned, and differentiate between economic groups according to possessions and currency listed. Trends of ownership for the whole period, the determination of individual occupations, and the occupational content of the people of the county at large are also discussed. Other areas focused on included the level of literacy, the role of religion in the lives of county residents, and in what manner county residents spent their leisure time. The results demonstrate that Princess Anne County was a rural, agriculturally-oriented section of Virginia conprised of three economic groups. The conclusions suggest that Princess Anne County was similar to other areas in America of the same period.

title: The Remarkable John Bigelow, Jr.: An Examination of Professionalism in the United States Army, 1877-91
Creators: name: Hansen Jr., Howard K.
Publisher: name: Old Dominion University Libraries
Year: 1986

description: This thesis describes the military career of John Bigelow, Jr. , with emphasis on the professional development of United States Army officers. It questions the role Bigelow played in the formation of army professionalism, a sense of corporate responsibility to exercise military expertise correctly. A focus on Bigelow to delineate professionalism in the army provides a fresh perspective of a pivotal period in American military history in the aftermath of the Civil War and before the United States started to build a colonial empire. Bigelow articulated a comprehensive concept of total^ar as he perceived its development in the United States. He developed a doctrine of total war against civilian populations based principally on the Civil War campaigns of William Tecumseh Sherman.

This study challenges many assumptions about the development of a military ethos within the army after the Civil War. Specifically, many military historians suggest that the U.S. Army’s isolation on the frontier, away from civilian society, fostered the professionalism that flourished during the period. A study of Bigelow’s diaries, papers, correspondence, and publications suggests instead that a close association with civilians, rather than isolation, may have been the catalyst for the development of military professionalism.

Creators: name: Valliant, Kevin Charles
Publisher: name: Old Dominion University Libraries
Year: 1995

description: As the federal government of the United States began its existence, the Chesapeake Bay had gone without a significant navigational aid for nearly two centuries. What factors then led the newly established government to build a lighthouse on Cape Henry, at the entrance of the Bay? Although the colonial governments of Virginia and Maryland failed to build a lighthouse, their efforts provided the groundwork for the Cape Henry light, which the federal government envisioned not only as a device to guide ships to safety, but as part of a system designed to ensure revenue for the new nation. This study will examine the construction of the lighthouse against the background of its perceived need by the colonial and national governments. Sources used for this work include the Calendar of Virginia State Papers, Hening's Statutes, the journals of the House of Burgesses, the Scharf Collection at the Maryland State Archives, and the records of federal lighthouse administration, located in the National Archives.

description: Experiments and computer simulations have shown that the melt-ing temperature of solid hydrogen drops with pressure above about 65 GPa, suggesting that a liquid state might exist at low temperatures. It has also been suggested that this low temperature liquid state might be non-molecular and metallic, although evidence for such behaviour is lacking. Here, we report results for hydrogen at high pressures using ab initio path-integral molecular dynamics methods, which include a description of the quantum motion of the protons at finite temperatures. We have determined the melting temperature as a function of pressure by direct simulation of the coexistence of the solid and liquid phases and have found an atomic solid phase from 500 to 800 GPa which melts at <200 K. Beyond this and up to pressures of 1200 GPa a metallic atomic liquid is stable at temperatures as low as 50 K. The quantum motion of the protons is critical to the low melting temperature in this system as ab initio simulations with classical nuclei lead to a considerably higher melting temperature of \sim300 K across the entire pressure range considered.

Creators: name: Madden, John P.

Year: 1988

description: The Bay of Pigs invasion in April 1961 was a political and military fiasco. President John F. Kennedy inherited the plan when he took office in January 1961. Even though there was a low probability of success, Kennedy still approved the operation. Because of the failure at the Bay of Pigs Kennedy lost faith in the Central Intelligence Agency (CIA) and the Joint Chiefs of Staff (JCS). Admiral Arleigh Burke, Chief of Naval Operations (CNO), endorsed the need to eliminate Fidel Castro. The role of the CIA is a well-worn subject, but what was the role of Admiral Burke and the U.S. Navy in the Bay of Pigs operation? This review is an historical perspective of the role of Burke and the Navy in the planning and execution of the Bay of Pigs invasion. It shows that Burke and the Navy did what they could to make a poor plan work, but it was not enough. The key failure was that it was a civilian-run operation without sufficient military support and involvement.

description: We analyse the relation between the emotions and the activity of contributors in the Open Source Software project Gentoo. Our case study builds on extensive data sets from the project's bug tracking platform Bugzilla, to quantify the activity of contributors, and its mail archives, to quantify the emotions of contributors by means of sentiment analysis. The Gentoo project is known for a period of centralization within its bug triaging community. This was followed by considerable changes in community organization and performance after the sudden retirement of the central contributor. We analyse how this event correlates with the negative emotions, both in bilateral email discussions with the central contributor, and at the level of the whole community of contributors. We then extend our study to consider the activity patterns on Gentoo contributors in general. We find that contributors are more likely to become inactive when they express strong positive or negative emotions in the bug tracker, or when they deviate from the expected value of emotions in the mailing list. We use these insights to develop a Bayesian classifier that detects the risk of contributors leaving the project. Our analysis opens new perspectives for measuring online contributor motivation by means of sentiment analysis and for real-time predictions of contributor turnover in Open Source Software projects.

title: United States Tactical Doctrine, 1855 to 1861: The Mismeasure of Technology
Creators: name: Armstrong Jr., Marion Vincent
Publisher: name: Old Dominion University Libraries
Year: 1991

description: This thesis illuminates the state of United States Army tactical doctrine at the beginning of the Civil War. In 1855, the weapons available to the United States Army left much to be desired in terms of firepower. Their limited range and lack of accuracy meant that they could not be relied upon to render the final decision in battle. The tactical system of 1855, however, blended this firepower with the shock action effect of bayonets and sabres, permitting the capabilities of the weaponry to be maximized on the battlefield while at the same time minimizing the deficiencies.

This harmony between weapons and tactics was not to be long lived. In June 1855, the United States Army adopted the rifled musket which greatly increased the firepower capability of the infantry. However, the effect that this new firepower would have on the conduct of battle was not understood. Military manuals and literature published between 1855 and 1861 failed to adequately prepare the officer corps of 1861 for the carnage this weapon would produce on the battlefields of 1861 to 1865.

description: This thesis examines the American participation in the development of resistance against the Japanese on Mindanao Island in the Philippines, 1942-1945. Americans directed the overall resistance movement and commanded most of the provinces. As leaders Americans played a key role in the evolution of the resistance from an independent guerrilla force to a partisan force that gave U.S. forces combat and intelligence assistance. The most important information for the thesis came from the MacArthur Archives, the Hayden Papers at the University of Michigan, the U.S. Army Military History Institute at Carlisle Barracks, and correspondence with 14 men who served with the Mindanao resistance.

Creators: name: Meyer, Emanuel
Publisher: name: Old Dominion University Libraries
Year: 1984

description: This biography examines Colonel Walter Herron Taylor’s involvement in the development of Norfolk, Virginia, into a modern urban seaport. Although this thesis depicts Taylor’s role as Robert E. Lee’s adjutant and Civil War historian, it clearly demonstrates that his civic accomplishments in the post-war era considerably outweighed his efforts for the Confederacy.

Colonel Taylor's lifetime career in banking and commerce reflected the changing society of the South from a backward province into a modern industrial and sophisticated section. The author illustrates the Colonel’s participation in Norfolk's growth from the stormy Reconstruction period to the eve of World War I. Throughout these years many significant municipal and social reforms were aided by, or were a direct result of, Colonel Taylor’s activities.

description: Blacks were the passive victims in Kemper County, Mississippi, the scene of violence and murder in Reconstruction. The Ku Klux Klan, the Order of '76, and a continuing animosity between scalawag Radical Republicans and white-line Democrats were instrumental in perpetuating a frontier atmosphere wherein the pistol and Bowie knife were commonplace. Shooting or killing was an acceptable method of settling one's differences with another. Freedom and new rights for the majority black population of the county and seven years of Radical rule in the county provoked night-riding violence, murder and finally, the Mississippi Plan, successful revolution at the ballot box in 1875. The revenge of the Democrats was not complete until April, 1877, when a mob stormed the county jail and murdered the former Radical Republican sheriff and two of his children.

description: In this paper, we propose a model based on wedge holography that can describe the multiverse. In wedge holography, we consider two gravitating baths, one of which has strong gravity and the other one has weak gravity. To describe a multiverse, we consider $2n$ Karch-Randall branes, and we propose that various $d$-dimensional universes are localized on these branes. These branes are embedded in $(d+1)$-dimensional spacetime. The model is useful in obtaining the Page curve of black holes with multiple horizons and in the resolution of the ``grandfather paradox''. We explicitly obtain the Page curves of eternal AdS black holes for $n=2$ multiverse and Schwarzschild de-Sitter black hole with two horizons.

description: Combining tight-binding models and first principles calculations, we investigate the quantum anomalous Hall (QAH) effect induced by intrinsic spin-orbit coupling (SOC) in buckled honeycomb lattice with sp orbitals in an external exchange field. Detailed analysis reveals that nontrivial topological properties can arise utilizing not only spin but also orbital degrees of freedom in the strong SOC limit, when the bands acquire non-zero Chern numbers upon undergoing the so-called orbital purification. As a prototype of a buckled honeycomb lattice with strong SOC we choose the Bi(111) bilayer, analyzing its topological properties in detail. In particular, we show the emergence of several QAH phases upon spin exchange of the Chern numbers as a function of SOC strength and magnitude of the exchange field. Interestingly, we observe that in one of such phases, namely, in the quantum spin Chern insulator phase, the quantized charge and spin Hall conductivities co-exist. We consider the possibility of tuning the SOC strength in Bi bilayer via alloying with isoelectronic Sb, and speculate that exotic properties could be expected in such an alloyed system owing to the competition of the topological properties of its constituents. Finally, we demonstrate that 3d dopants can be used to induce a sizeable exchange field in Bi(111) bilayer, resulting in non-trivial Chern insulator properties.

description: The input of recently photosynthesized C has significant implications on soil organic C sequestration, and in paddy soils, both plants and soil microbes contribute to the overall C input. In the present study, we investigated the fate and priming effect of organic C from different sources by conducting a 300-day incubation study with four different 13C-labelled substrates: rice shoots (shoot-C), rice roots (root-C), rice rhizodeposits (rhizo-C), and microbe-assimilated C (micro-C). The efflux of both 13CO2 and 13CH4 indicated that the mineralization of C in shoot-C-, root-C-, rhizo-C-, and micro-C-treated soils rapidly increased at the beginning of the incubation and decreased gradually afterwards. The highest cumulative C mineralization was observed in root-C-treated soil (45.4 %), followed by shoot-C- (31.9 %), rhizo-C- (7.90 %), and micro-C-treated (7.70 %) soils, which corresponded with mean residence times of 39.5, 50.3, 66.2, and 195 days, respectively. Shoot and root addition increased C emission from native soil organic carbon (SOC), up to 11.4 and 2.3 times higher than that of the control soil by day 20, and decreased thereafter. Throughout the incubation period, the priming effect of shoot-C on CO2 and CH4 emission was strongly positive; however, root-C did not exhibit a significant positive priming effect. Although the total C contents of rhizo-C- (1.89 %) and micro-C-treated soils (1.90 %) were higher than those of untreated soil (1.81 %), no significant differences in cumulative C emissions were observed. Given that about 0.3 and 0.1 % of the cumulative C emission were derived from labelled rhizo-C and micro-C, we concluded that the soil organic C-derived emissions were lower in rhizo-C- and micro-C-treated soils than in untreated soil. This indicates that rhizodeposits and microbe-assimilated C could be used to reduce the mineralization of native SOC and to effectively improve soil C sequestration. The contrasting behaviour of the different photosynthesized C substrates suggests that recycling rice roots in paddies is more beneficial than recycling shoots and demonstrates the importance of increasing rhizodeposits and microbe-assimilated C in paddy soils via nutrient management.
Non-Steady wall-bounded flows of viscoelastic fluids under periodic forcing

description: The problem of oscillating flows inside pipes under periodic forcing of viscoelastic fluids is addressed here. Starting from the linear Oldroyd-B model, a generalized Darcy's law is obtained in frequency domain and an explicit expression for the dependence of the dynamic permeability on fluid parameters and forcing frequency is derived. Previous results in both viscoelastic and Newtonian fluids are here shown to be particular cases of our results. On the basis of our calculations, a possible explanation for the observed damping of local dynamic response as the forcing frequency increases is given. Good fitting with recent experimental studies of wave propagation in viscoelastic media is here exhibited. Sound wave propagation in viscoelastic media flowing inside straight pipes is investigated. In particular, we obtain the local dynamic response for weakly compressible flows.

description: Composite plants consisting of a wild-type shoot and a transgenic root are frequently used for functional genomics in legume research. Although transformation of roots using Agrobacterium rhizogenes leads to morphologically normal roots, the question arises as to whether such roots interact with arbuscular mycorrhizal (AM) fungi in the same way as wild-type roots. To address this question, roots transformed with a vector containing the fluorescence marker DsRed were used to analyse AM in terms of mycorrhization rate, morphology of fungal and plant subcellular structures, as well as transcript and secondary metabolite accumulations. Mycorrhization rate, appearance, and developmental stages of arbuscules were identical in both types of roots. Using Mt16kOLI1Plus microarrays, transcript profiling of mycorrhizal roots showed that 222 and 73 genes exhibited at least a 2-fold induction and less than half of the expression, respectively, most of them described as AM regulated in the same direction in wild-type roots. To verify this, typical AM marker genes were analysed by quantitative reverse transcription-PCR and revealed equal transcript accumulation in transgenic and wild-type roots. Regarding secondary metabolites, several isoflavonoids and apocarotenoids, all known to accumulate in mycorrhizal wild-type roots, have been found to be up-regulated in mycorrhizal in comparison with non-mycorrhizal transgenic roots. This set of data revealed a substantial similarity in mycorrhization of transgenic and wild-type roots of Medicago truncatula, validating the use of composite plants for studying AM-related effects.
No Infinite Tail Beats Optimal Spatial Search

description: Farhi and Gutmann (Physical Review A, 57(4):2403, 1998) proved that a continuous-time analogue of Grover search (also called spatial search) is optimal on the complete graphs. We extend this result by showing that spatial search remains optimal in a complete graph even in the presence of an infinitely long path (or tail). If we view the latter as an external quantum system that has a limited but nontrivial interaction with our finite quantum system, this suggests that spatial search is robust against a coherent infinite one-dimensional probe. Moreover, we show that the search algorithm is oblivious in that it does not need to know whether the tail is present or not, and if so, where it is attached to.

description: This article discusses the issues of organizing foreign language classes in primary school. Early learning of a foreign language is carried out mainly through play activities aimed at the development and education of the child, which socializes the child and develops his personal characteristics. However, the problem of early education has been considered for several centuries and is actively studied by modern psychologists, scientists, teachers and methodologists. However, there are special requirements for teaching a foreign language in primary school.
