description: Ensemble-based quantum memories are key to developing multiplexed quantum repeaters, able to overcome the intrinsic rate limitation imposed by finite communication times over long distances. Rare-earth ion doped crystals are main candidates for highly multimode quantum memories, where time, frequency and spatial multiplexing can be exploited to store multiple modes. In this context the atomic frequency comb (AFC) quantum memory provides large temporal multimode capacity, which can readily be combined with multiplexing in frequency and space. In this article, we derive theoretical formulas for quantifying the temporal multimode capacity of AFC-based memories, for both optical memories with fixed storage time and spin-wave memories with longer storage times and on-demand read out. The temporal multimode capacity is expressed in key memory parameters, such as AFC bandwidth, fixed-delay storage time, memory efficiency, and control field Rabi frequency. Current experiments in europium- and praseodymium-doped Y$_2$SiO$_5$ are analyzed within this theoretical framework, and prospects for higher temporal capacity in these materials are considered. In addition we consider the possibility of spectral and spatial multiplexing to further increase the mode capacity, with examples given for both rare earh ions.

description: A medicina veterinária integrativa (MVI) incorpora os aspectos eficazes dos cuidados usuais, também denominados de convencionais ou tradicionais, com os complementares para conseguir o melhor estado de saúde para os pacientes. É bastante extensa a lista de terapias potenciais neste campo que vai desde a Acupuntura, Homeopatia, Reabilitação e medicina esportiva, Medicina regenerativa (ou seja, células estaminais ou plaquetas terapia), Ozonoterapia, Medicina Canábica entre outras técnicas. Todas as ferramentas da medicina veterinária integrativa, complementar e/ou alternativa precisam de evidências sobre sua eficácia. Para isso, faz-se necessário que essas técnicas estejam presentes em revistas científicas indexadas com discussão de casos clínicos e ensaios controlados com modelos animais para promoção de debates sobre as ações fisiológicas produzidas nos animais submetidos a estes tratamentos. O objetivo dos trabalhos desenvolvidos será de promover discussões sobre técnicas de MVI e procurar publicar os resultados em encontros, congressos e em periódicos científicos. Palavras-chave: Medicina veterinária integrativa, Acupuntura, Ozonoterapia, Homeopatia, Medicina canábica.

description: Shiba bands formed by overlapping Yu-Shiba-Rusinov subgap states in magnetic impurities on a superconductor play an important role in topological superconductors. Here, we theoretically demonstrate the existence of a new type of Shiba bands (dubbed topological Shiba metal) on a magnetically doped $s$-wave superconducting surface with Rashba spin-orbit coupling in the presence of a weak in-plane magnetic field. Such topological gapless Shiba bands develop from gapped Shiba bands through Lifshitz phase transitions accompanied by second-order quantum phase transitions for the intrinsic thermal Hall conductance. We also find a mechanism in Shiba lattices that protects the first-order quantum phase transitions for the intrinsic thermal Hall conductance. Due to the long-range hopping in Shiba lattices, the topological Shiba metal exhibits intrinsic thermal Hall conductance with large nonquantized values. As a consequence, there emerge a large number of second-order quantum phase transitions.

description: Electrospray ion-beam deposition (ES-IBD) is a versatile tool to study structure and reactivity of molecules from small metal clusters to large protein assemblies. It brings molecules gently into the gas phase where they can be accurately manipulated and purified, followed by controlled deposition onto various substrates. In combination with imaging techniques, direct structural information of well-defined molecules can be obtained, which is essential to test and interpret results from indirect mass spectrometry techniques. To date, ion-beam deposition experiments are limited to a small number of custom instruments worldwide, and there are no commercial alternatives. Here we present a module that adds ion-beam deposition capabilities to a popular commercial MS platform (Thermo Scientific$^{\mathrm{TM}}$ Q Exactive$^{\mathrm{TM}}$ UHMR). This combination significantly reduces the overhead associated with custom instruments, while benefiting from established high performance and reliability. We present current performance characteristics including beam intensity, landing-energy control, and deposition spot size for a broad range of molecules. In combination with atomic force microscopy (AFM) and transmission electron microscopy (TEM), we distinguish near-native from unfolded proteins and show retention of native shape of protein assemblies after dehydration and deposition. Further, we use an enzymatic assay to quantify activity of an non-covalent protein complex after deposition an a dry surface. Together, these results indicate a great potential of ES-IBD for applications in structural biology, but also outline the challenges that need to be solved for it to reach its full potential.

description: André's celebrated Theorem of 1998 implies that each complex straight line (apart from obvious exceptions) contains at most finitely many points whose both coordinates are j-invariants of elliptic curves with complex multiplication. We show that there are only a finite number of such lines which contain more than two such points. As there is a line through any two complex points, this is best possible.

description: The respiratory and the cardiovascular systems are key components for the efficient distribution of oxygen throughout the organism. As such, any small disturbance in their activity will jeopardize the performance of the equine athlete compromising muscular function and exercise recovery. Thus, the aim of this research group is to investigate equine exercise physiology, including respiratory and cardiovascular physiology, and to explore how respiratory and cardiovascular disfunction affect the equine athlete. Most studies on equine exercise physiology are based either on Thoroughbreds or Arabian horses. However in Portugal, the most common horse breed is the Lusitano horse which has different attributes from the aforementioned breeds. Thus, part of the work of this research groups includes investigating how Lusitanos’ adapt to training protocols, by evaluating the physiological adaptations of the cardiovascular system to a training protocol. This project will include ultrasound examination and electrocardiogram of the heart, as well as evaluation of perfusion indicators. Additionally, our goal is to also conduct research on diseases that can lead to poor performance. One example is our research on equine asthma, which resulted in the development of a staging method with lung function testing (pleural pressure and plethysmography). We are also planning to investigate if a specific population of neutrophils can be used in the diagnosis of severe equine asthma, if tomosynthesis we can aid in disease identification, and during this time we intend to begin collecting samples for future microbiome analysis. Keywords: Respiratory, Cardiovascular, Physiology, Equine asthma, Dynamic conditions.

description: There is no accurate, reasonable data to record war fatalities regarding the dead and paralyzed combatants and civilians, the devastation of physical property, and the amount of environmental degradation in Afghanistan. Afghanistan fails to consider the environmental challenges as the cost of war. The country cannot disregard this issue. The country passed environmental law after seven years of the interim government. Furthermore, the law does little to deter ecoterrorism and those who endanger the ecosystem in the state. The study considers how war has fuelled catastrophic environmental degradation that has resulted in land contamination, forest destruction, resource looting, and climate change, forcing the mass migration of people within and across borders and creating threats to human health. The Fourth Geneva Convention is a set of international laws the United Nations has already adopted to lessen the environmental damage caused by armed conflict. This law has not, however, stemmed the war's environmental harm. To provide a better explanation than what is now available and, on its subtext, what the social renovation model needs to bear to stand the test of time and challenges, we would engage in the argument and contextualize it with the research related to the battle against the background in this study. This existing study is employed a doctrinal legal approach in which part of the literature will be reviewed to acquire the necessary data using normative approaches. The current research is limited to environmental degradation caused by armed conflict post-2001.

description: Jump Oriented Programming attacks pose a security threat against modern processors. In order to enhance the security of designs based on the RISC-V architecture, a set of ISA extensions, namely the Forward-Edge Control Flow Integrity (CFI) ISA extension, have been proposed and are currently under evaluation by the relevant RISC-V committees. This thesis presents the implementation and evaluation of the CFI ISA extension on the CVA6 soft processor core. The study leveraged the Genesys2 board as the hardware platform and the Verilator simulator for experimentation. The CFI extension was integrated into the CVA6 core, ensuring robust protection against potential security vulnerabilities stemming from JOP attacks. Notably, the performance overhead incurred by this security enhancement was limited to a mere 2%, demonstrating its minimal impact on system efficiency. Furthermore, the area utilization overhead on the Genesys2 board was effectively managed, with an minimal impact compared to the original design. This research underscores the feasibility of bolstering system security through ISA extensions, while preserving system performance and resource utilization at highly acceptable levels.

Για να ενισχυθεί η ασφάλεια των σχεδιασμών που βασίζονται στην αρχιτεκτονική RISC-V, προτάθηκε ένα σύνολο επεκτάσεων εντολών αρχιτεκτονικής (ISA), που ονομάζεται  ̈Επεκτάσεις της αρχιτεκτονικής συνόλου εντολών RISC-V για υποστήριξη ελέγχου ακεραιότητας ροής έμμεσων διακλαδώσεων ̈, η οποία αυτήν τη στιγμή βρίσκεται υπό αξιολόγηση από τις σχετικές επιτροπές του RISC-V.

Η μελέτη χρησιμοποίησε την πλακέτα Genesys2 ως πλατφόρμα υλικού και τον προσομοιωτή Verilator για πειράματα. Η επέκταση της Ακεραιότητα Ροής Εκτέλεσης(CFI) ενσωματώθηκε στον πυρήνα CVA6, εξασφαλίζοντας αξιόπιστη προστασία από δυνητικά προβλήματα ασφάλειας που προκύπτουν από επιθέσεις προγραμματισμού με άλματα (JOP). Είναι σημαντικό να σημειωθεί ότι η επιβράδυνση που προκλήθηκε από αυτήν την ενίσχυση της ασφάλειας περιορίστηκε σε μόλις 2%, καταδεικνύοντας την ελάχιστη επίδρασή της στην απόδοση του συστήματος. Επιπλέον, η αύξηση χρήσης των πόρων στην πλακέτα Genesys2 διαχειρίστηκε αποτελεσματικά, με ελάχιστη αύξηση σε σύγκριση με τον αρχικό σχεδιασμό. Αυτή η έρευνα υπογραμμίζει ότι είναι εφικτή η ενίσχυση της ασφάλειας του συστήματος μέσω επεκτάσεων εντολών αρχιτεκτονικής (ISA), διατηρώντας ταυτόχρονα την απόδοση του συστήματος και τη χρήση πόρων σε πολύ αποδεκτά επίπεδα.

description: This paper is devoted to tetrahedron maps, which are set-theoretical solutions to the Zamolodchikov tetrahedron equation. We construct a family of tetrahedron maps on associative rings. We show that matrix tetrahedron maps presented in [arXiv:2110.05998] are a particular case of our construction. This provides an algebraic explanation of the fact that the matrix maps from [arXiv:2110.05998] satisfy the tetrahedron equation. Also, Liouville integrability is established for some of the constructed maps.

description: A fisiologia do exercício tem o objetivo de estudar os ajustes morfofisiológicos gerados com a prática de atividades físicas por animais/homens. Devido a sua reconhecida habilidade e importância atlética, o equino é foco de diversas pesquisas. Cada disciplina equestre varia em grau de exigência muscular, força, agilidade, duração e velocidade, além de ser influenciado por fatores extrínsecos tais quais condições climáticas do local aonde as provas são realizadas. O principal objetivo é usar tais informações na avaliação do condicionamento físico, dos efeitos de programas de treinamento, no diagnóstico precoce de lesões e aumentar a vida útil de atletas. Mais recentemente, tais pesquisas mostram-se importantes na garantia do bem-estar desses equinos. Em Portugal, existem aproximadamente 37 mil equinos (2017), com destaque para a raça Lusitano, o cavalo de sela mais antigo do Mundo e a mais importante raça equina autóctone portuguesa. A raça vem se destacando na prática de provas de adestramento devido a sua conformação física. Dentre outras disciplinas equestres praticados em Portugal, há destaque também para as provas de saltos de obstáculos e raide. A proposta de nossa linha de investigação é estudar os efeitos agudos e crônicos da prática de desportos equestres em equinos criados e treinados em Portugal. Trabalhos iniciados pelo grupo com equinos lusitanos de dressage renderam publicação no ICEEP 2022 na Suécia, com previsão futura de estudar a inflamação nesses mesmos animais. Ainda, foi desenvolvido estudo com cavalos de saltos de obstáculos. Projetos futuros incluem equinos em provas de toureio e uso da passadeira aquática.

description: We prove several de Finetti theorems for the unitary dual group, also called the Brown algebra. Firstly, we provide a finite de Finetti theorem characterizing $R$-diagonal elements with an identical distribution. This is surprising, since it applies to finite sequences in contrast to the de Finetti theorems for classical and quantum groups; also, it does not involve any known independence notion. Secondly, considering infinite sequences in $W^*$-probability spaces, our characterization boils down to operator-valued free centered circular elements, as in the case of the unitary quantum group $U_n^+$. Thirdly, the above de Finetti theorems build on dual group actions, the natural action when viewing the Brown algebra as a dual group. However, we may also equip the Brown algebra with a bialgebra action, which is closer to the quantum group setting in a way. But then, we obtain a no-go de Finetti theorem: invariance under the bialgebra action of the Brown algebra yields zero sequences, in $W^*$-probability spaces. On the other hand, if we drop the assumption of faithful states in $W^*$-probability spaces, we obtain a non-trivial half a de Finetti theorem similar to the case of the dual group action.

description: In 2014, Wang and Cai established the following harmonic congruence for any odd prime $p$ and positive integer $r$, \begin{equation*} Z(p^{r})\equiv-2p^{r-1}B_{p-3} ~(\bmod ~ p^{r}), \end{equation*} where $ Z(n)=\sum\limits_{i+j+k=n\atop{i,j,k\in\mathcal{P}_{n}}}\frac{1}{ijk}$ and $\mathcal{P}_{n}$ denote the set of positive integers which are prime to $n$. In this note, we obtain a congruence for distinct odd primes $p,~q$ and positive integers $α,~β$, \begin{equation*} Z(p^αq^β)\equiv 2(2-q)(1-\frac{1}{q^{3}})p^{α-1}q^{β-1}B_{p-3}\pmod{p^α} \end{equation*} and the necessary and sufficient condition for \begin{equation*} Z(p^αq^β)\equiv 0\pmod{p^αq^β}. \end{equation*} Finally, we raise a conjecture that for $n>1$ and odd prime power $p^α||n$, $α\geq1$, \begin{eqnarray} \nonumber Z(n)\equiv \prod\limits_{q|n\atop{q\neq p}}(1-\frac{2}{q})(1-\frac{1}{q^{3}})(-\frac{2n}{p})B_{p-3}\pmod{p^α}. \end{eqnarray}

A tarefa deste trabalho está relacionada com a valorização aquapónica da água resultante da Técnica de Precipitação Química (PQ) e a utilização da lama resultante como substrato para o desenvolvimento de larvas da mosca-soldado-negro (Black soldier Fly - BSF) (Hermetia illucens L. 1758). Materiais e métodos: Esta avaliação é realizada através da dissecção e processamento histopatológico das larvas BSF para avaliação microscópica do trato digestivo e comparação entre grupos. As diferentes metodologias para o desenvolvimento desta tarefa contemplam: dissecção de larvas de BSF alimentadas com a lama proveniente da TPQ, assim como o posterior processamento histopatológico das mesmas. As larvas são dissecadas mediante a técnica descrita por Zoe & Martin (2003) e o trato intestinal é posicionado nas cassetes usando a técnica de Swiss-rolling, os tecidos são fixados em formol ao 10 %. São realizados cortes histológicos de 3 µm e processados para coloração de rotina (HE) e posterior observação. Resultados: Nesta fase otimizamos o protocolo de processamento para realizar a análise histológica de vários grupos de amostras, focando-se principalmente na identificação dos diferentes segmentos do intestino descritos e os seus componentes celulares. Perspetivas de Futuro: Para o futuro, após a otimização do processamento histopatológico, serão comparados os resultados observados entre as larvas alimentadas com diferentes lamas e o grupo controlo e será avaliado seu efeito no trato digestivo das larvas da BSF.

description: The exomoon candidate Kepler-1708 b-i was recently reported using two transits of Kepler data. Supported by a 1% false-positive probability, the candidate is promising but requires follow-up observations to confirm/reject its validity. In this paper, we consider the detectability of the exomoon candidate's transit, most specifically in the next window (March 2023) using the WFC3 instrument aboard the Hubble Space Telescope (HST). Using realistic noise estimates, accounting for the visit-long trends, and propagating the model posteriors derived using the Kepler data, we perform 75 injection-recovery trials with Bayesian model selection. Defining a successful detection as one which meets thresholds of the Bayes factor, AIC, and error of the retrieved parameters, only 7 of our 75 injections were recovered when considering HST data alone. This implies a true-positive probability (TPP) of $10\pm3$%. Despite HST's superior aperture to Kepler, both instrumental systematics and the compactness of the candidate exomoon's orbit typically obfuscate a strong detection. Although the noise properties of the James Webb Space Telescope (JWST) have not yet been characterized in flight, we estimate the signal would be easily recovered using NIRSpec operating in its Bright Object Time Series mode.

Random quantum circuits are approximate unitary $t$-designs in depth $O\left(nt^{5+o(1)}\right)$

description: The applications of random quantum circuits range from quantum computing and quantum many-body systems to the physics of black holes. Many of these applications are related to the generation of quantum pseudorandomness: Random quantum circuits are known to approximate unitary $t$-designs. Unitary $t$-designs are probability distributions that mimic Haar randomness up to $t$th moments. In a seminal paper, Brandão, Harrow and Horodecki prove that random quantum circuits on qubits in a brickwork architecture of depth $O(n t^{10.5})$ are approximate unitary $t$-designs. In this work, we revisit this argument, which lower bounds the spectral gap of moment operators for local random quantum circuits by $Ω(n^{-1}t^{-9.5})$. We improve this lower bound to $Ω(n^{-1}t^{-4-o(1)})$, where the $o(1)$ term goes to $0$ as $t\to\infty$. A direct consequence of this scaling is that random quantum circuits generate approximate unitary $t$-designs in depth $O(nt^{5+o(1)})$. Our techniques involve Gao's quantum union bound and the unreasonable effectiveness of the Clifford group. As an auxiliary result, we prove fast convergence to the Haar measure for random Clifford unitaries interleaved with Haar random single qubit unitaries.

description: In recent years we have witnessed a concentrated effort to make sense of thermodynamics for small-scale systems. One of the main difficulties is to capture a suitable notion of work that models realistically the purpose of quantum machines, in an analogous way to the role played, for macroscopic machines, by the energy stored in the idealisation of a lifted weight. Despite of several attempts to resolve this issue by putting forward specific models, these are far from capturing realistically the transitions that a quantum machine is expected to perform. In this work, we adopt a novel strategy by considering arbitrary kinds of systems that one can attach to a quantum thermal machine and seeking for work quantifiers. These are functions that measure the value of a transition and generalise the concept of work beyond the model of a lifted weight. We do so by imposing simple operational axioms that any reasonable work quantifier must fulfil and by deriving from them stringent mathematical condition with a clear physical interpretation. Our approach allows us to derive much of the structure of the theory of thermodynamics without taking as a primitive the definition of work. We can derive, for any work quantifier, a quantitative second law in the sense of bounding the work that can be performed using some non-equilibrium resource by the work that is needed to create it. We also discuss in detail the role of reversibility and correlations in connection with the second law. Furthermore, we recover the usual identification of work with energy in degrees of freedom with vanishing entropy as a particular case of our formalism. Our mathematical results can be formulated abstractly and are general enough to carry over to other resource theories than quantum thermodynamics.

AGU position statement on data

description: Enabling FAIR Data in the Earth, Space, and Environmental Sciences: Encouraging all Researchers to Document, Share, and Cite Scientific Data In addition to the iPoster, this talk introduces the most recent update to AGU's position statement on data, the call to action, and the working happening across the community (Enabling FAIR Data) and within AGU journals to support the Commitment Statement. Abstract: AGU’s data position statement, recently updated, affirms that “Earth and space science data are a world heritage, and an essential part of the science ecosystem. All players in the science ecosystem—researchers, repositories, publishers, funders, institutions, etc.—should work to ensure that relevant scientific evidence is processed, shared, and used ethically, and is available, preserved, documented, and fairly credited.” (https://www.agu.org/Share-and-Advocate/Share/Policymakers/Position-Statements/Position_Data) The statement includes key objectives for the Geosciences: Champion Open and Transparent Data Enable a Robust Science Ecosystem Create Effective Culture Change Our research ecosystem is diverse and interconnected involving researchers, publishers, editors, repositories, institutions, librarians, societies, funders and more. The effort to evolve practices for open and FAIR data sharing in support of Open Science requires all participants. At the American Geophysical Union we are convening and encouraging adoption of updated data practices across the ecosystem to support open and FAIR data and the resources needed by researchers to comply with this updated guidance. The Enabling FAIR Data Commitment Statement gives a path specific to each stakeholder to support progress. (https://copdess.org/enabling-fair-data-project/commitment-statement-in-the-earth-space-and-environmental-sciences/) With JpGU, EGU, and AOGS as partners in this effort, we continue to steadily make progress toward making open and FAIR data a common practice in the Geosciences. We will share the current progress and provide recommendations for how participants can encourage incremental actions in their own organizations.
Unsteady aerodynamic theory for membrane wings

description: We study analytically the dynamic response of membrane aerofoils subject to arbitrary, small-amplitude chord motions and transverse gusts in a two-dimensional inviscid incompressible flow. The theoretical model assumes linear deformations of an extensible membrane under constant tension, which are coupled aeroelastically to external aerodynamic loads using unsteady thin aerofoil theory. The structural and aerodynamic membrane responses are investigated for harmonic heave oscillations, an instantaneous change in angle of attack, sinusoidal transverse gusts, and a sharp-edged gust. The unsteady lift responses for these scenarios produce aeroelastic extensions to the Theodorsen, Wagner, Sears, and Küssner functions, respectively, for a membrane aerofoil. These extensions incorporate for the first time membrane fluid-structure interaction into the expressions for the unsteady lift response of a flexible aerofoil. Our results suggest that membrane aerofoils with appropriately tuned pretension could possess substantial aerodynamic benefits over rigid aerofoils in unsteady flow conditions.

description: Precision measurements at the LHC and future colliders require theory predictions with uncertainties at the percent level for many observables. Theory uncertainties due to the perturbative truncation are particularly relevant and must be reduced to fully exploit the physics potential of collider experiments. In recent years the theoretical high energy physics community has made tremendous analytical and numerical advances to address this challenge. In this white paper, we survey state-of-the-art calculations in perturbative quantum field theory for collider phenomenology with a particular focus on the computational requirements at high perturbative orders. We show that these calculations can have specific high-performance-computing (HPC) profiles that should to be taken into account in future HPC resource planning.

Future Time Perspective: Opportunities and Limitations Are Differentially Associated with Subjective Well-Being and Hair Cortisol Concentration

description: Background: Future time perspective has been associated with subjective well-being, though depending on the line of research considered either an open-ended future time perspective or a limited future time perspective has been associated with high well-being. Most of this research however has conceptualized future time perspective as a one-dimensional construct, whereas recent evidence has demonstrated that there are likely at least two different underlying dimensions, a focus on opportunities and a focus on limitations. This project first seeks to replicate the two-dimensional structure of the Future Time Perspective Scale, and then examines the associations these dimensions may have with different measures of subjective well-being and a biological index of chronic stress. Objective: To test if the two dimensions of the Future Time Perspective Scale, a focus on opportunities and a focus on limitations, differentially associate with two measures of subjective well-being and a biological indicator of chronic stress, namely hair cortisol. Method: Sixty-six community-dwelling participants with a mean age of 72 years (SD = 5.83) completed the Future Time Perspective Scale, Center for Epidemiologic Studies Depression Scale, and Philadelphia Geriatric Center Morale Scale. Participants also provided a 3-cm-long hair strand to index cortisol accumulation over the past 3 months. Following the results of a factor analysis, a mediation model was created for each dimension of the Future Time Perspective Scale, and significance testing was done through a bootstrapping approach to harness maximal statistical power. Results: Factor analysis results replicated the two-dimensional structure of the Future Time Perspective Scale. Both dimensions were then found to have unique associations with well-being. Specifically, a high focus on opportunities was associated with fewer depressive symptoms and higher morale, whereas a low focus on limitations was associated with reduced hair cortisol, though this association was mediated by subjective well-being. Conclusion: Results replicate and extend previous research by pointing to the multi-dimensional nature of the Future Time Perspective Scale. While an open future time perspective was overall beneficial for well-being, the exact association each dimension had with well-being differed depending on whether subjective measures of well-being or biological indices of chronic stress were considered.

description: We perform 3+1D viscous hydrodynamics calculations of proton-nucleus (pA) and nucleus-nucleus (AA) collisions. Our goal is to understand the apparent collective behavior recently observed in pA collisions and to verify whether the highest multiplicity collision systems can be accurately described as a relativistic fluid. We compare our calculations of flow variables to existing measurements, and demonstrate that hydrodynamics correctly captures the measured trends. We show that our predictions for the pair correlation observable $r_n$ are validated by recent experimental pA measurements, and that our results are sensitive to the granularity of the initial state. We also compare our results with measurements done for nucleus-nucleus collisions.

description: Excerpts from the report: The Potomac basin embraces an area of about 14,600 square miles. It includes the District of Columbia and parts of Maryland, West Virginia, Virginia, and Pennsylvania. It has a population of nearly 3 million people. The beauty of the streams, fields, and forests of the basin has made it a recreational area for increasing thousands of people. The terrain of the basin varies from the flat Coastal Plains to the mountainous eastern slope of the Alleghenies. Between these extremes are the rolling country of the Piedmont Plateau, the Great Valley of the Shenandoah, and the Appalachian Highlands. This report is based on a study of the water and related land resources in the Potomac River basin and presents that part of the comprehensive plan for the prevention or control of floods and the development and conservation of the water and related land resources with respect to present and future needs in the upstream portions of the basin. The Department of Agriculture developed information on: (1) trends in agricultural development and their relation to present and future water needs for agriculture, (2) erosion as it relates to the sediment and pollution problems, (3) local needs for water control and management in the upstream areas, and (4) the potential of upstream development for meeting these problems.
description: The Corps of Engineers has been authorized by two resolutions of the Senate Committee on Public Works to prepare a comprehensive plan for the control of floods and the development and conservation of water and related resources in the Potomac River basin. The survey was initiated under the provisions contained in the resolution adopted January 26, 1956, by the Committee on Public Works of the United States Senate. The Department of Agriculture participated in the survey under the provisions of section 6 of the Watershed Protection and Flood Prevention Act (Public Law 566, 83rd Congress, as amended) which authorizes the Secretary of Agriculture to cooperate with other Federal, state, and local agencies in surveys and investigations of the watersheds of rivers and other waterways to develop coordinated programs. The Soil Conservation Service, Forest Service, and Economic Research Service carried out the Department of Agriculture's part of the survey.
