description: Based on the spin-density-matrix approach, both the electric-field-induced spin accumulation and the spin current are systematically studied for the two-dimensional Rashba model. Eigenmodes of spin excitations give rise to resonances in the frequency domain. Utilizing a general and physically well-founded definition of the spin current, we obtain results that differ remarkably from previous findings. It is shown that there is a close relationship between the spin accumulation and the spin current, which is due to the prescription of a quasi-chemical potential and which does not result from a conservation law. Physical ambiguities are removed that plagued former approaches with respect to a spin-Hall current that is independent of the electric field. For the clean Rashba model, the intrinsic spin-Hall conductivity exhibits a logarithmic divergency in the low-frequency regime.

description: The Sloan Digital Sky Survey is the largest redshift survey conducted to date, and the principal survey observations have all been conducted on the dedicated SDSS 2.5m and 0.5m telescopes at Apache Point Observatory. While the whole survey has many unique features, this article concentrates on a description of the systems surrounding the dual fibre-input spectrographs that obtain all the survey spectra and that are capable of recording 5,760 individual spectra per night on an industrial, consistent, mass-production basis. It is hoped that the successes and lessons learned will prove instructive for future large spectrographic surveys.

description: In this paper, we propose an inverse-kinematics controller for a class of multi-robot systems in the scenario of sampled communication. The goal is to make a group of robots perform trajectory tracking in a coordinated way when the sampling time of communications is much larger than the sampling time of low-level controllers, disrupting theoretical convergence guarantees of standard control design in continuous time. Given a desired trajectory in configuration space which is precomputed offline, the proposed controller receives configuration measurements, possibly via wireless, to re-compute velocity references for the robots, which are tracked by a low-level controller. We propose joint design of a sampled proportional feedback plus a novel continuous-time feedforward that linearizes the dynamics around the reference trajectory: this method is amenable to distributed communication implementation where only one broadcast transmission is needed per sample. Also, we provide closed-form expressions for instability and stability regions and convergence rate in terms of proportional gain $k$ and sampling period $T$. We test the proposed control strategy via numerical simulations in the scenario of cooperative aerial manipulation of a cable-suspended load using a realistic simulator (Fly-Crane). Finally, we compare our proposed controller with centralized approaches that adapt the feedback gain online through smart heuristics, and show that it achieves comparable performance.

description: In the financial sector, a reliable forecast the future financial performance of a company is of great importance for investors' investment decisions. In this paper we compare long-term short-term memory (LSTM) networks to temporal convolution network (TCNs) in the prediction of future earnings per share (EPS). The experimental analysis is based on quarterly financial reporting data and daily stock market returns. For a broad sample of US firms, we find that both LSTMs outperform the naive persistent model with up to 30.0% more accurate predictions, while TCNs achieve and an improvement of 30.8%. Both types of networks are at least as accurate as analysts and exceed them by up to 12.2% (LSTM) and 13.2% (TCN).

description: Founded in 1888, the Imperial Japanese Naval Academy at Etajima was the culmination of a three decade long period of naval educational development that spanned the end of the Tokugawa Shogunate (1603 to 1868) and the restoration of Imperial power under the Meiji Emperor (reigned from 30 January 1867 to 30 July 1912) . In the time since its founding, the vast majority of commissioned officers in both the Imperial Japanese Navy (IJN) and the Japanese Maritime Self Defense Force (JMSDF) have been graduates of the Etajima Academy. As a result, the Etajima Academy has been the single most important influence on the development and character of the Japanese sea services for the past 135 years. Given this fact, there is surprisingly little information to be found in English language sources concerning the Academy and its influence on both the IJN and the JMSDF. By shedding more light on the training of Japanese naval officers, the primary purpose of this project is to better understand the development of the officer corps within the IJN. By examining the history of officer development within the IJN this project also attempts to understand the confluence of influences that made the Japanese officer corps and the IJN a distinct and powerful player on the world stage.

description: Upcoming biosignature searches focus on indirect indicators to infer the presence of life on other worlds. Aside from just signaling the presence of life, however, some biosignatures can contain information about the state that a planet's biosphere has achieved. This additional information can be used to measure what fractions of planets achieve certain key stages, corresponding to the advent of life, photosynthesis, multicellularity, and technological civilization. We forecast the uncertainties of each measurement for upcoming surveys, and outline the key factors that determine these uncertainties. Our approach is probabilistic and relies on large numbers of candidates rather than detailed examination of individual exoplanet spectra. The dependence on survey size, likeliness of the transition, and several measures of degrees of confidence are discussed, including discussion of geological false positives in biosignatures as well as how combining data from different missions can affect the inference. Our analysis should influence policy recommendations for future mission design and strategy to minimize the impact of measurement uncertainties.

description: A many-electron conducting system undergoes free acceleration in response to a macroscopic field. The Drude weight $D$---also called charge stiffness---measures the adiabatic (inverse) inertia of the electrons; the $D$ formal expression requires periodic boundary conditions. When instead a bounded sample is addressed within open boundary conditions, no current flows and a constant (external) field only polarizes the sample: the Faraday cage effect. Nonetheless a low-frequency field induces forced oscillations: we show here that the low-frequency linear response of the bounded system is dominated by the adiabatic inertia and allows an alternative evaluation of $D$. Simulations on model one-dimensional systems demonstrate our main message.

A recipe for accurate estimation of lifespan brain trajectories, distinguishing longitudinal and cohort effects

description: We address the problem of estimating how different parts of the brain develop and change throughout the lifespan, and how these trajectories are affected by genetic and environmental factors. Estimation of these lifespan trajectories is statistically challenging, since their shapes are typically highly nonlinear, and although true change can only be quantified by longitudinal examinations, as follow-up intervals in neuroimaging studies typically cover less than 10 \% of the lifespan, use of cross-sectional information is necessary. Linear mixed models (LMMs) and structural equation models (SEMs) commonly used in longitudinal analysis rely on assumptions which are typically not met with lifespan data, in particular when the data consist of observations combined from multiple studies. While LMMs require a priori specification of a polynomial functional form, SEMs do not easily handle data with unstructured time intervals between measurements. Generalized additive mixed models (GAMMs) offer an attractive alternative, and in this paper we propose various ways of formulating GAMMs for estimation of lifespan trajectories of 12 brain regions, using a large longitudinal dataset and realistic simulation experiments. We show that GAMMs are able to more accurately fit lifespan trajectories, distinguish longitudinal and cross-sectional effects, and estimate effects of genetic and environmental exposures. Finally, we discuss and contrast questions related to lifespan research which strictly require repeated measures data and questions which can be answered with a single measurement per participant, and in the latter case, which simplifying assumptions that need to be made. The examples are accompanied with R code, providing a tutorial for researchers interested in using GAMMs.
Cohomological $χ$-independence for Higgs bundles and Gopakumar-Vafa invariants

description: The aim of this paper is two-fold: Firstly, we prove Toda's $χ$-independence conjecture for Gopakumar--Vafa invariants of arbitrary local curves. Secondly, following Davison's work, we introduce the BPS cohomology for moduli spaces of Higgs bundles of rank $r$ and Euler characteristic $χ$ which are not necessary coprime, and show that it does not depend on $χ$. This result extends the Hausel--Thaddeus conjecture on the $χ$-independence of E-polynomials proved by Mellit, Groechenig--Wyss--Ziegler and Yu in two ways: we obtain an isomorphism of mixed Hodge modules on the Hitchin base rather than an equality of E-polynomials, and we do not need the coprime assumption.
 The proof of these results is based on a description of the moduli stack of one-dimensional coherent sheaves on a local curve as a global critical locus which is obtained in the companion paper by the first author and Naruki Masuda.

The effects of the generation II unloader express brace on medial compartment knee osteoarthritis
Creators: name: Yeung, Peter Lap-Tak
Publisher: name: University of British Columbia

description: Osteoarthritis (OA) is a disease characterized by the deterioration of cartilage, formation of osteophytes, and subchondral sclerosis. So far, there is nothing available to stop disease progression or reverse disease symptoms. Bracing has been found to be an alternative to more invasive measures to reduce symptoms in individuals with knee OA. Twenty-one subjects (14 male, 7 female) enrolled in a twelve week repeated measures study. There were three brace conditions: no brace (control), brace in neutral (placebo), and brace adjusted to four degrees valgus. All subjects underwent each condition in the same sequence. There was a three week washout period between the neutral and valgus brace conditions. A questionnaire, adapted from the WOMAC, was designed for this study showed good reliability (r = 0.89 to r = 0.93) for the three parameters assessed This study found wearing the valgus brace significantly minimized the increase in pain (p = 0.037), difficulty in function (p = 0.032), and stiffness (p = 0.021) experienced after activity compared to wearing the neutral brace. The results of this study suggest that the Generation II Orthotics Unloader Express is an effective treatment for those suffering mild forms of osteoarthritis.

description: The n-particle periodic Toda chain is a well known example of an integrable but nonseparable Hamiltonian system in R^{2n}. We show that Sigma_k, the k-fold singularities of the Toda chain, ie points where there exist k independent linear relations amongst the gradients of the integrals of motion, coincide with points where there are k (doubly) degenerate eigenvalues of representatives L and Lbar of the two inequivalent classes of Lax matrices (corresponding to degenerate periodic or antiperiodic solutions of the associated second-order difference equation). The singularities are shown to be nondegenerate, so that Sigma_k is a codimension-2k symplectic submanifold. Sigma_k is shown to be of elliptic type, and the frequencies of transverse oscillations under Hamiltonians which fix Sigma_k are computed in terms of spectral data of the Lax matrices. If mu(C) is the (even) Maslov index of a closed curve C in the regular component of R^{2n}, then (-1)^{μ(C)/2} is given by the product of the holonomies (equal to +/- 1) of the even- (or odd-) indexed eigenvector bundles of L and Lmat.

description: Student performance of virtual introductory physics class (calculus-based mechanics) is analyzed. A fully web-enhanced class was done synchronously. The analysis is done in two categories, averaging all mid-exams (or chapter exams) and cumulative final exams. It shows that students perform well with shorter timed mid-semester assessments (or chapter exams) than the longer timed assessments. Results were then compared with two survey questions to investigate the effect of the background knowledge of physics and calculus on their performance. It shows two interesting results, a) students with basic conceptual background knowledge of physics perform well, b) calculus knowledge does not correlate well with student performance. These findings can be used to rethink and redesign the assessments for calculus-based introductory physics classes. Also, the findings can be used to develop a supplemental support program to enhance student performance.

description: The Heckman two-stage procedure is used to identify and rank the determinants of internal and external credit rationing in rural households using data sourced from two districts in the former KwaZulu homeland. The results confirm international findings that high transaction costs faced by rural households limit their access to formal credit markets. Income and savings levels are significant determinants of the level of credit obtained, with savings acting as a substitute for credit. Better access to financial markets will require public investment in rural infrastructure, literacy and vocational training, and legal reform in order to lower transaction costs, improve income levels, and facilitate the efficient use of collateral. Savings lose their value as a source of information when lending institutions are distinct from savings institutions, and moveable assets carry high collateral-specific risk in the absence of an efficient judicial system.

description: Crowd models can be used for the simulation of people movement in the built environment. Crowd model outputs have been used for evaluating safety and comfort of pedestrians, inform crowd management and perform forensic investigations. Microscopic crowd models allow the representation of each person and the obtainment of information concerning their location over time and interactions with the physical space/other people. Pandemics such as COVID-19 have posed several questions on safe building usage, given the risk of disease transmission among building occupants. Here we show how crowd modelling can be used to assess occupant exposure in confined spaces. The policies adopted concerning building usage and social distancing during a pandemic can vary greatly, and they are mostly based on the macroscopic analysis of the spread of disease rather than a safety assessment performed at a building level. The proposed model allows the investigation of occupant exposure in buildings based on the analysis of microscopic people movement. Risk assessment is performed by retrofitting crowd models with a universal model for exposure assessment which can account for different types of disease transmissions. This work allows policy makers to perform informed decisions concerning building usage during a pandemic.

description: Red meat is international business and meat companies in Namibia are global role players. Poultry consumption increased at the expense of beef primarily because of consistency and pricing, while larger beef and sheep meat suppliers are making inroads in the growth markets of the world. Ultimately, to be successful, companies must carve out a clear position for themselves, in the light of competition, and must exploit their competitive advantages to the full. A study was commissioned to determine the strategic success factors, approaches and options of the major beef and sheep meat exporting industries of the world for extrapolation on Namibia. The most common business strategy involves cost orientation, although a differentiated focus strategy with innovative and branded products targeted into niche markets is clearly needed for Namibian businesses. Developments in traceability, quality control, branding, added-value and consistency should satisfy the concerns consumers have over health and safety issues and assure repurchases of Namibian meat products.

description: In this letter, we study the scattering of light by a single subwavelength slit in a metal screen. In contrast to previous theoretical works, we provide a microscopic description of the scattering process by emphasizing the generation of surface plasmons at the slit apertures. The analysis is supported by a rigorous formalism based on a normal-mode-decomposition technique and by a semi-analytical model which provides accurate formulae for the plasmonic generation strengths. The generation is shown to be fairly efficient for metals with a low conductivity, like gold in the visible regime. Verification of the theory is also shown by comparison with recent experimental data [H.F. Schouten et al., Phys. Rev. Lett. 94, 053901 (2005)].

description: In South Africa a recent government study laid the foundations for improving access to financial services for rural people. More is however needed than simply stating the policies. It is argued that policies do not differentiate target groups adequately. This can result in inefficient implementation of policies. The concept of a broad range of institutional possibilities to improve access to financial services, none of which specifically provides a conclusive model, is considered to be realistic. The idea is to muster this range of possible forms into a co-ordinated effort to increase access to financial services for rural people in all rural areas. This paper emphasises the reality of the situation when choosing policy directions. NGOs, commercial banks and the Post Bank do not hold the primary key to improving access to financial services in rural areas in South Africa. Several studies discussed the broad range of possible institutional forms in the rural areas of South Africa. The role of decentralised financial systems has not been the focus point of any of these studies. It is argued that fertile ground exists in South Africa for decentralised financial systems to address access problems at the local level. Decentralised systems also cannot be the solution to all intermediation problems. A multipronged approach is proposed, harnessing all institutional forms into a comprehensive strategy.

description: Entanglement has become central for the characterization of quantum matter both in and out of equilibrium. In a dynamical context entanglement exhibits universal linear temporal growth in generic systems, which stems from the underlying linear light cones as they occur in planar geometries. Inhomogeneous spacetimes can lead, however, to strongly bent trajectories. While such bent trajectories crucially impact correlation spreading and therefore the light-cone structure, it has remained elusive how this influences the entanglement dynamics. In this work we investigate the real-time evolution of the entanglement entropy in one-dimensional quantum systems after quenches which change the underlying spacetime background of the Hamiltonian. Concretely, we focus on the Rindler space describing the spacetime in close vicinity to a black hole. As a main result we find that entanglement grows sublinearly in a generic fashion both for interacting and noninteracting quantum matter. We further observe that the asymptotic relaxation becomes exponential, as opposed to algebraic for planar Minkowski spacetimes, and that in the vicinity of the black hole the relaxation time for large subsystems becomes independent of the subsystem size. We study entanglement dynamics both for the case of noninteracting fermions, allowing for exact numerical solutions, and for random unitary circuits representing a paradigmatic class of ergodic systems.

description: The bosonic quantum channels have recently attracted a growing interest, motivated by the hope that they open a tractable approach to the generally hard problem of evaluating quantum channel capacities. These studies, however, have always been restricted to memoryless channels. Here, it is shown that the classical capacity of a bosonic Gaussian channel with memory can be significantly enhanced if entangled symbols are used instead of product symbols. For example, the capacity of a photonic channel with 70%-correlated thermal noise of one third the shot noise is enhanced by about 11% when using 3.8-dB entangled light with a modulation variance equal to the shot noise.

description: We introduce the shuffle of deformed permutahedra (a.k.a. generalized permutahedra), a simple associative operation obtained as the Cartesian product followed by the Minkowski sum with the graphical zonotope of a complete bipartite graph. Besides preserving the class of graphical zonotopes (the shuffle of two graphical zonotopes is the graphical zonotope of the join of the graphs), this operation is particularly relevant when applied to the classical permutahedra and associahedra. First, the shuffle of an $m$-permutahedron with an $n$-associahedron gives the $(m,n)$-multiplihedron, whose face structure is encoded by $m$-painted $n$-trees, generalizing the classical multiplihedron. We show in particular that the graph of the $(m,n)$-multiplihedron is the Hasse diagram of a lattice generalizing the weak order on permutations and the Tamari lattice on binary trees. Second, the shuffle of an $m$-associahedron with an $n$-associahedron gives the $(m,n)$-constrainahedron, whose face structure is encoded by $(m,n)$-cotrees, and reflects collisions of particles constrained on a grid. Third, the shuffle of an $m$-anti-associahedron with an $n$-associahedron gives the $(m,n)$-biassociahedron, whose face structure is encoded by $(m,n)$-bitrees, with relevant connections to bialgebras up to homotopy. We provide explicit vertex, facet, and Minkowski sum descriptions of these polytopes, as well as summation formulas for their $f$-polynomials based on generating functionology of decorated trees.

Charge-exchange dipole excitations in deformed nuclei

description: Background: The electric giant-dipole resonance (GDR) is the most established collective vibrational mode of excitation. A charge-exchange analog, however, has been poorly studied in comparison with the spin (magnetic) dipole resonance (SDR). Purpose: I investigate the role of deformation on the charge-exchange dipole excitations and explore the generic features as an isovector mode of excitation. Methods: The nuclear energy-density functional method is employed for calculating the response functions based on the Skyrme--Kohn--Sham--Bogoliubov method and the proton-neuton quasiparticle-random-phase approximation. Results: The deformation splitting into $K=0$ and $K=\pm 1$ components occurs in the charge-changing channels and is proportional to the magnitude of deformation as is well known for the GDR. For the SDR, however, a simple assertion based on geometry of a nucleus cannot be applied for explaining the vibrational frequencies of each $K$-component. A qualitative argument on the strength distributions for each component is given based on the non-energy-weighted sum rules taking nuclear deformation into account. The concentration of the electric dipole strengths in low energy and below the giant resonance is found in neutron-rich unstable nuclei. Conclusions: The deformation splitting occurs generically for the charge-exchange dipole excitions as in the neutral channel. The analog pygmy dipole resonance can emerge in deformed neutron-rich nuclei as well as in spherical systems.

description: Despite the fact that all direct and indirect measures of subsidisation and protection have been removed, commercial agriculture is still widely considered to be subsidised, privileged and uncompetitive. This paper shows how the process of deregulation has in fact changed the situation. The paper reports on the comparative advantage in the production of wheat in South Africa and reveals the various distortionary effects, if any, of the policy environment on the production of wheat in the country prior to 1997. The paper concludes that South Africa has a strong comparative advantage in the production of wheat, especially, in the inland areas. Favourable climatic and soil factors as well as abundant and relatively cheaper domestic factors of production may be some of the reasons for this strong comparative advantage. The inland areas have better RCRs due to higher inland transportation costs. However, wheat production under irrigation seems to have no comparative advantage. This is mainly due to the implicit subsidy on irrigation water.

description: Chromatic symmetric functions are well-studied symmetric functions in algebraic combinatorics that generalize the chromatic polynomial and are related to Hessenberg varieties and diagonal harmonics. Motivated by the Stanley--Stembridge conjecture, we show that the allowable coloring weights for indifference graphs of Dyck paths are the lattice points of a permutahedron $\mathcal{P}_λ$, and we give a formula for the dominant weight $λ$. Furthermore, we conjecture that such chromatic symmetric functions are Lorentzian, a property introduced by Brändén and Huh as a bridge between discrete convex analysis and concavity properties in combinatorics, and we prove this conjecture for abelian Dyck paths. We extend our results on the Newton polytope to incomparability graphs of (3+1)-free posets, and we give a number of conjectures and results stemming from our work, including results on the complexity of computing the coefficients and relations with the $ζ$ map from diagonal harmonics.

A Survey on Split Manufacturing: Attacks, Defenses, and Challenges

description: In today's integrated circuit (IC) ecosystem, owning a foundry is not economically viable, and therefore most IC design houses are now working under a fabless business model. In order to overcome security concerns associated with the outsorcing of IC fabrication, the Split Manufacturing technique was proposed. In Split Manufacturing, the Front End of Line (FEOL) layers (transistors and lower metal layers) are fabricated at an untrusted high-end foundry, while the Back End of Line (BEOL) layers (higher metal layers) are manufactured at a trusted low-end foundry. This approach hides the BEOL connections from the untrusted foundry, thus preventing overproduction and piracy threats. However, many works demonstrate that BEOL connections can be derived by exploiting layout characteristics that are introduced by heuristics employed in typical floorplanning, placement, and routing algorithms. Since straightforward Split Manufacturing may not afford a desirable security level, many authors propose defense techniques to be used along with Split Manufacturing. In our survey, we present a detailed overview of the technique, the many types of attacks towards Split Manufacturing, as well as possible defense techniques described in the literature. For the attacks, we present a concise discussion on the different threat models and assumptions, while for the defenses we classify the studies into three categories: proximity perturbation, wire lifting, and layout obfuscation. The main outcome of our survey is to highlight the discrepancy between many studies -- some claim netlists can be reconstructed with near perfect precision, while others claim marginal success in retrieving BEOL connections. Finally, we also discuss future trends and challenges inherent to Split Manufacturing, including the fundamental difficulty of evaluating the efficiency of the technique.

description: Recently we have shown that $YbInCu_4$ and related compounds present a solid state Pomeranchuk effect. These systems have a first order volume transition where a local moment phase coexists with a renormalized Fermi liquid in analogy with $^3He$ at its melting curve. We demonstrate here experimentally that the solid state Pomeranchuk effect, controlled by a magnetic field, can be used to produce cooling.

description: In recent years there has been a growth in the interest of consumers to buy more locally. An increasing number of farmers are trying to meet the growing demand for locally produced products. Here in New York State, farmers who are direct marketing their product, either direct to consumer or direct to wholesale markets constantly are looking for additional avenues to connect to current customers or grow their customer base. NY MarketMaker is one avenue farmers across New York can utilize to make connections with their customers. This powerhouse database connects buyers, sellers and transportation services and is easily searchable, even for the „technologically‟ challenged. Cornell Cooperative Extension (CUCE) in New York City began this project with the University of Illinois in 2007, and today the CUCE MarketMaker web site contains information on 3,391 food producers representing vegetables, fruits and nuts, dairy, grains, herbs, wine, and meat products from 56 counties. Our site, which contains over 84,000 New York food-related references, is part of a national network of state web sites that currently includes 15 states. MarketMaker is a FREE in-depth marketing tool to help small and mid-sized producers get sophisticated data to help them reach thousands of potential buyers. New York State producers can get listed on the site at no charge, access census data to determine where targeted buyers are located in a given area, and find markets for products – such as farmers‟ markets, grocery stores, restaurants, and other retail locations- in a map-based format. We created our own educational outreach program that would teach food entrepreneurs how to use the site and the basics of marketing value added food products. The main purpose of MarketMaker is to level the playing field. With this tool, small and mid-sized producers have similar market intelligence as the bigger producers. From July 2007 to December 2009, a total of 45 hands-on MarketMaker presentations were given for producers at conferences, meetings, expos, harvest fairs and Empire Farm Days; New York MarketMaker received 934 new registrations and over 1.5 million hits. Many buyers and sellers actively posted advertisements at the MarketPlace. CUCE staff members conducted 23 online training sessions; participants were farm business management specialists, agricultural economic development specialists, fruits and vegetables specialists, and dairy specialists from across the state.
"insert.html" of "Dark matter interpretations of ATLAS searches for the electroweak production of supersymmetric particles in $\sqrt{s} = 8$ TeV proton-proton collisions"
Creators: name: ATLAS Collaboration
Publisher: name: HEPData

description: insert.html
description: A selection of searches by the ATLAS experiment at the LHC for the electroweak production of SUSY particles are used to study their impact on the constraints on dark matter candidates. The searches use $20\,{\rm fb}^{-1}$ proton--proton collision data at $\sqrt{s}=8\,$TeV. A likelihood-driven scan of a five-dimensional effective model focusing on the gaugino--higgsino and Higgs sector of the phenomenological minimal supersymmetric Standard Model is performed. This scan uses data from direct dark matter detection experiments, the relic dark matter density and precision flavour physics results. Further constraints from the ATLAS Higgs mass measurement and SUSY searches at LEP are also applied. A subset of models selected from this scan are used to assess the impact of the selected ATLAS searches in this five-dimensional parameter space. These ATLAS searches substantially impact those models for which the mass $m({\tilde{\chi}}_0^1)$ of the lightest neutralino is less than $65\,$GeV, excluding 86\% of such models. The searches have limited impact on models with larger $m({\tilde{\chi}}_0^1)$ due to either heavy electroweakinos or compressed mass spectra where the mass splittings between the produced particles and the lightest supersymmetric particle is small.

description: Production of the lightest MSSM Higgs boson h is studied at the LHC. Isorate contours for the h -> gamma gamma and h -> tau+tau- decay channels are shown in the m_A,tan(beta) parameter space. Effects of the SUSY parameters, in particular the stop mixing and stop quark mass, are investigated. Search strategies at the LHC are discussed and the discovery potential is calculated for the CMS experiment. The MSSM parameter space for m_A > 150-200 GeV is expected to be covered with at least one decay channel with an integrated luminosity of 60 fb^{-1}. A light stop quark with large stop mixing can affect seriously the discovery potential in the h -> gamma gamma and h -> ZZ* decay channels.
