description: Farm and farm-related industries accounted for almost 18 percent of total U.S, employment in 1988. This share is based on a broad definition of the agricultural sector, including not only farm production but also industries that mine, manufacture, and sell farm inputs; process commodities; and sell consumer goods. Employment in these industries is used to measure the size and importance of the agricultural sector in U.S. regions and metropolitan (metro) and nonmetropolitan (nonmetro) areas. Defining and measuring the agricultural sector helps inform decisionmakers who must weigh the demands of agriculture against competing economic activities when making policy, developing programs, and allocating budget dollars.

description: After the Second World War, many of the former European colonies in Southeast Asia aspired to independence. The French resisted these movements in Indochina even after independence was declared in Vietnam. The Viet Minh fought the first Indochina War against the former colonial masters, using what resources were available to them. France was an industrial power with comparatively vast wealth and military power yet they were fought to a standstill at Dien Bien Phu in 1954. This thesis examines some of the methods used by the Viet Minh to marshal their resources, which comprised the people of Vietnam, particularly from the northern Viet Bac region, to build an opponent that proved equal to one of the large European powers. The techniques used by the Viet Minh leadership focussed closely on the folk traditions and the shared understanding of the history of the people that they wished to engage in the fight for independence. The mobilisation techniques used, including the propaganda employed, proved to be a weapon powerful enough to dislodge the well-armed adversary.
A non-linear mathematical model for the X-ray variability classes of the microquasar GRS 1915+105 -- I: quiescent, spiking states and QPOs

description: The microquasar GRS 1915+105 is known to exhibit a very variable X-ray emission on different time scales and patterns. We propose a system of two ordinary differential equations, adapted from the Hindmarsh-Rose model, with two dynamical variables x(t), y(t) and an input constant parameter J_0, to which we added a random white noise, whose solutions for the x(t) variable reproduce consistently the X-ray light curves of several variability classes as well as the development of low frequency Quasi-Periodic Oscillations (QPO). We show that changing only the value of J_0 the system moves from stable to unstable solutions and the resulting light curves reproduce those of the quiescent classes like phi and chi, the delta class and the spiking rho class. Moreover, we found that increasing the values of J_0 the system induces high frequency oscillations that evolve to QPO when it moves into another stable region. This system of differential equations gives then a unified view of the variability of GRS 1915+105 in term of transitions between stable and unstable states driven by a single input function J_0. We also present the results of a stability analysis of the equilibrium points and some considerations on the existence of periodic solutions.

A Simple Gradient Flow Equation for the Bounce Solution
Creators: name: Sato, Ryosuke
Publisher: name: Deutsches Elektronen-Synchrotron, DESY, Hamburg
Year: 2019

description: Motivated by the recent work of Chigusa, Moroi, and Shoji, we propose a new simple gradient flow equation to derive the bounce solution which contributes to the decay of the false vacuum. Our discussion utilizes the discussion of Coleman, Glaser, and Martin and we solve a minimization problem of the kinetic energy while fixing the potential energy. The bounce solution is derived as a scale-transformed of the solution of this problem.

description: The majority of the sexual function questionnaires concentrate on a single gender rather than assessing sexual problems as a dyadic unit. The Golombok Rust Inventory of Sexual Satisfaction (GRISS) was designed to assess sexual function in both partners. We evaluated the validity and reliability of GRISS in patients with stress urinary incontinence and their respective partners.

Sixty-six couples were included. There were low levels of missing data (<1%). (Presented in the order of English, Chinese and Malay). Cronbach's alpha for the male total score were 0.82, 0.88 and 0.95. For the female total score, Cronbach's alpha were 0.76, 0.78 and 0.88. Most subscales had acceptable internal consistency (Cronbach's alpha >0.70). Test-retest reliability was assessed in 44 clinically stable cases. Intraclass correlation coefficients for the male total score were 0.93, 0.94 and 0.99, while intraclass correlation coefficients for the female total score were 0.89, 0.86 and 0.88. Most subscales had good test-retest reliability (intraclass correlation coefficient >0.80).

The English, Chinese and Malay versions each proved to be valid and reliable to evaluate sexual function in our Malaysian population.

description: Although effects of environmental stress exposure on animal personality have been widely explored, few studies have taken a multiple stressor perspective. We performed a literature review and synthesis to identify important pathways whereby interplay among multiple stressors could contribute to personality variation, and how personality might affect responses to multiple stressor suites. This Supplementary Material explains the methodology and search results of our review, and how we drew on these results when writing the text of our review paper. Furthermore, this Supplementary Material also includes a Supplementary Table (Table S1) and Figure (Figure S1). Table S1 contains a non-exhaustive list of studies identified in our review that consider a) effects of various multiple stressor combinations on personality variation, and b) how personality types may differentially respond to stressors. Figure S1 involves a) how the combination and intensity of multiple stressors may determine whether viabile behavioural alternatives for balancing life-history tradeoffs exist, and b) how behavioural alternatives for negotiating multi-stress landscapes might exist, even independent of balance of life-history tradeoffs.
Making a genome work for you and the community
Creators: name: Papanicolaou, Alexie
Publisher: name: F1000Research

description: Overview
The molecular biology community has overcome a major bottleneck: inexpensive access to near-complete genome sequence from multiple species. Such diversity of sequence information underpins a new type of genomic capability and greatly benefits the comparative genomics field. How can we, however, make best produce such resources? Here we present a sample of our Genome Train concept: best-practice protocols for successfully completing a genome project and ensuring an impactful legacy.

Why this matters
Each community has their own goals for producing a genome. Often it is to support a specific research program but then it can evolve into a major resource that includes not only a sequence and an Official Gene Set but also a variety of functional annotations. Ultimately, however, it can become a resource for the broader biological field. By ensuring these resources are of high quality they can be used in a comparative fashion to address the ultimate question in molecular evolutionary biology: What is the genetic blueprint of a species and how did it come to be so. But this is easier said than done; luckily a vast array of informatic resources has been – and will continue to be – developed to facilitate this process.

description: Instructional design, a field of theory and practice established within education and corporate education training, is shifting in today's modern technological world. Once only focused on the content of the established curriculum and the traditional (paper, pencil) ways of presenting that information, now, instructional designers are faced with the challenge of leading the way for innovative e-learning training and solutions using the latest technology trends and tools. In this report, I will examine current instructional design models and their approaches, then compare the models to the design process of Design Thinking. This report will showcase the assumption that utilizing the Design Thinking framework within the established instructional design models will elevate the instructional design field and current learning solutions, therefore allowing for the instructional design field to continue to grow.

Guiding walks across fitness landscapes – modelling epistatic interactions with probabilistic evolutionary kernel functions
Creators: name: Zaugg, Julian
name: Bodén, Mikael
name: Yosephine Gumulya
Publisher: name: F1000Research
Year: 2015

description: Evolutionary trajectories available to a protein are constrained by the presence of epistatic interactions – their presence increases the ruggedness of the fitness land scape. Identification and characterisation of such interactions through multiple simul taneous mutations creates a ‘combinatorial explosion’ of sequence possiblities, which cannot be fully explored experimentally. Small exploratory sequence-function datasets provide a sparse snapshot of the fitness landscape topology, however given the presence of potentially strong epistatic effects, such as within the active site, current statistical approaches cannot provide reliable models describing the mapping of sequence to function.

Using the template Aspergillus niger epoxide hydrolase sequence – used as a template in such a we identify a set of homologous sequences, derived from the ESTHER database, and construct a representative alignment. We then apply co-evolution statistical methods, such as mutual information and SCA, in order to gain insight into which mutation locations are under epistatic influence. Such information provides us with a degree of ‘prior’ knowledge of significant residue interactions for the protein family of interest, which can be incorporated into our models to improve our mapping from sequence to function. Based on a model of evolution, in this case an instantaneous rate matrix, we have applied a probabilistic evolutionary kernel function to map our sequences to a higher-dimensional vector space and have applied kernel principal component analysis and support vector machine methods to evaluate the kernel function's sensitivity to amino acid changes across mutation locations.

We are now in the process of creating a new version of this kernel function that can incorporate higher-order dependencies between positions.

Thus the method, proposed in [1] for systems with finite number of degrees of freedom is generalized to infinite-dimensional Hamiltonian systems. The construction method is illustrated on the explicit nontrivial example of RHF of ATFT related to the exceptional algebras E_6 and E_7. The involutions of the local integrals of motion are proved by means of the classical R-matrix approach.

description: To support rich semantic analysis of text, traditional natural language processing tools require access to a cache of static knowledge with both broad coverage and deep meaning.  Acquiring this knowledge by hand is so expensive and error-prone, it has been dubbed the knowledge acquisition bottleneck.  In this work, we present a method for reducing the impact of this bottleneck by automating the knowledge acquisition task using the novel approach of bootstrapping a machine learner with a fully-realized semantic analysis engine, creating a life-long learner. We present an overview of our learner: a system that automatically produces lexical and ontological knowledge resources by building a corpus of raw texts from the web, semantically analyzing them to the best ability of the existing engine, and extracting the word meanings.  We expand on this overview by presenting a series of experiments in chronological order, each evolving on the previous one as we explore the possibilities presented by our methodology. Finally, we explore a series of improvements to our system: we discuss a variety of changes to individual components, as well as complete methodological shifts.  These discussions will set the stage for the next round of interesting experiments in pursuit of a fully automatic language learner.
title: Developing a New Synthesis Strategy for Fe-N-C Catalysts for the Oxygen Reduction Reaction in Proton-Exchange-Membrane Fuel Cells
Creators: name: Kübler, Markus
Publisher: name: UNSPECIFIED
Year: 2021

description: Within this work, a new synthesis method for a Fe-N-C catalyst is developed. Fe-N-C catalysts are considered promising materials for the replacement of expensive Pt and catalyze the oxygen reduction reaction (ORR) on the cathode inside proton-exchange-membrane fuel cells (PEMFCs). This work briefly summarizes the standpoint of current PEMFC technology and provides a detailed overview on the to this day reported synthesis methods and applied precursors for Fe-N-C catalysts. One major concern with the synthesis of Fe-N-C catalysts is that for a high performance often complex precursors like porphyrins or zeolitic imidazolate frameworks (ZIFs) are used. These precursors are expensive or not well suited for a scale-up [1-3]. Here, a new method is presented which is based on a cheap and simple polypyrrole precursor which at the same time yields catalysts with a high fuel cell performance. Important parameters for the new preparation method are systematically investigated and useful insights, for instance on the influence of the iron salt precursor, a bimetallic iron and manganese approach, the heat-treatment temperature, or the effectiveness of the acid leaching, are presented. The final catalyst of this work is compared to the best-off performing Fe-N-C catalysts reported in literature. Further, the overall preparation method is briefly discussed with respect to its scale-up practicability by comparing the individual synthesis steps to the to this day commercially most advanced Fe-N-C catalysts.

World cities and peripheral development: The interplay of gateways and subordinate places in Argentina and Ghana’s upstream oil and gas sector

description: Serving as “gateways”, some world cities tie their wider hinterlands to global networks. The article revisits gateway–hinterland relations against the backdrop of assessments that lead to opposed conclusions on the benefits and shortcomings of integration into the world economy. Referring to the oil and gas sector in Argentina and Ghana, it answers the question of how gateways interact with subordinate places and also uncovers obstacles to peripheral development. The author finds that Accra and Buenos Aires concentrate corporate control. Argentina's capital serves as a gateway for knowledge generation and logistics too. Opportunities for peripheral development in both countries are considerable, albeit largely limited to generic services. Besides a certain concentration of business activities in the gateway cities, more important challenges to peripheral development are typical for small and medium enterprises (insufficient finance and management capabilities, unawareness of business opportunities, and the like). They include rent seeking and subcontracting. The latter leaves local companies in a particularly weak position vis‐à‐vis lead firms. The author argues that while integration into the world economy allows for peripheral development, the corresponding outcomes may not meet everyone's expectations. Related expectations must, therefore, be more down‐to‐earth than overly optimistic statements frequently made by politicians.

description: Current radial velocity data from specialized instruments contain a large amount of information that may pass unnoticed if their analysis is not accurate. The joint use of Bayesian inference tools and frequency analysis has been shown effective to reveal exoplanets but they have been used less frequently to investigate stellar activity. We intend to use radial velocity data of the exoplanet host star GJ 3512 to investigate its magnetic activity. Our study includes the analysis of the photometric data available. The main objectives of our work are to constrain the orbital parameters of the exoplanets in the system, to determine the current level of activity of the star and to derive an activity cycle length for it. An adaptive importance sampling method was used to determine the parameters of the exoplanets orbit. Generalized Lomb-Scargle periodograms were constructed with both radial velocity curve and photometric data. A careful analysis of the harmonic frequencies was conducted in each periodogram. Our fit to multiple Keplerian orbits constrained the orbital parameters of two giant gas planets orbiting the star GJ 3512. The host star showed an increase of its magnetic activity during the last observing campaign. The accurate fit of the radial velocity curve data to the multi-Keplerian orbit permitted to reveal the star rotation in the residuals of the best fit and estimate an activity cycle length of ~ 14 years.

description: Using large scale quantum Monte Carlo simulations and dual vortex theory we analyze the ground state phase diagram of hard-core bosons on the kagome lattice with nearest neighbor repulsion. In contrast to the case of a triangular lattice, no supersolid emerges for strong interactions. While a uniform superfluid prevails at half-filling, two novel solid phases emerge at densities $ρ=1/3$ and $ρ=2/3$. These solids exhibit an only partial ordering of the bosonic density, allowing for local resonances on a subset of hexagons of the kagome lattice. We provide evidence for a weakly first-order phase transition at the quantum melting point between these solid phases and the superfluid.

description: Balanced colorings of networks classify robust synchrony patterns -- those that are defined by subspaces that are flow-invariant for all admissible ODEs. In symmetric networks the obvious balanced colorings are orbit colorings, where colors correspond to orbits of a subgroup of the symmetry group. All other balanced colorings are said to be exotic. We analyze balanced colorings for two closely related types of network encountered in applications: trained Wilson networks, which occur in models of binocular rivalry, and opinion networks, which occur in models of decision making. We give two examples of exotic colorings which apply to both types of network, and prove that Wilson networks with at most two learned patterns have no exotic colorings. We discuss how exotic colorings affect the existence and stability of branches for bifurcations of the corresponding model ODEs.

description: The complex time evolution in the X-ray light curves of the peculiar black hole binary GRS 1915+105 can be obtained as solutions of a non-linear system of ordinary differential equations derived form the Hindmarsch-Rose model and modified introducing an input function depending on time. In the first paper,assuming a constant input with a superposed white noise, we reproduced light curves of the classes rho, chi, and delta. We use this mathematical model to reproduce light curves, including some interesting details, of other eight GRS 1915+105 variability classes either considering a variable input function or with small changes of the equation parameters. On the basis of this extended model and its equilibrium states, we can arrange most of the classes in three main types: i) stable equilibrium patterns: (classes phi, chi, alpha'', theta, xi, and omega) whose light curve modulation follows the same time scale of the input function, because changes occur around stable equilibrium points; ii) unstable equilibrium patterns: characterised by series of spikes (class rho) originated by a limit cycle around an unstable equilibrium point; iii) transition pattern: (classes delta, gamma, lambda, kappa and alpha'), in which random changes of the input function induce transitions from stable to unstable regions originating either slow changes or spiking, and the occurrence of dips and red noise. We present a possible physical interpretation of the model based on the similarity between an equilibrium curve and literature results obtained by numerical integrations of a slim disc equations.

description: We demonstrate that SrRuO3 and CaRuO3 thin films undergo a room temperature structural phase transition driven by the substrate imposed epitaxial biaxial strain. As tensile strain increases, ARuO3 (A=Ca, Sr) films transform from the orthorhombic phase which is usually observed in bulk SrRuO3 and CaRuO3 at room temperature, into a tetragonal phase which in bulk samples is only stable at higher temperatures. More importantly, we show that the observed phenomenon strongly affects the electronic and magnetic properties of ARuO3 thin films that are grown on different single crystal substrates which in turn offers the possibility to tune these properties.

description: We analyze and model the infrared spectrum of the Cassiopeia A supernova remnant, with the aim of determining the masses of various elements in the unshocked ejecta. In this way we complement the survey of the X-ray emitting ejecta of Hwang & Laming (2012) to provide a complete census of the elemental composition of the Cas A ejecta. We calculate photoionization-recombination equilibria to determine the ionization balance of various elements in the ejecta as a function of density, using the X-ray and UV emission from the forward and reverse shocks as the ionizing radiation. With the assumption that all emission lines are principally excited at the ejecta density that maximizes their emission, we can convert observed line intensities into element masses. We find that the majority of the $\sim 3 $M_sun ejecta have already been through the reverse shock and are seen today in X-rays. A minority, $\sim 0.47\pm 0.05$ M_sun, with uncertainties quoted here coming from the data fitting procedure only, are still expanding inside the reverse shock and emitting in the infrared. This component is comprised mainly of O, Si, and S, with no Fe readily detectable. Incorporating uncertainties estimated to come from our modeling, we quote $0.47 \pm {0.47\atop 0.24}$ M_sun. We speculate that up to a further 0.07 M_sun of Fe may be present in diffuse gas in the inner ejecta, depending on the Fe charge state.

description: Background:  Prior to January 2009, sexual assault victims were denied access to forensic services unless they reported their assault to police. The 2005 reauthorization of the Violence Against Women Act (VAWA 2005) eliminated this requirement and required states to provide sexual assault victims access to free forensic services without police involvement. The state of Maryland instituted Jane Doe Reporting (JDR) in response to VAWA 2005.   Purpose of Study:  (1) Describe JDR victims and JDR victims who convert to police involvement (JDR converters); (2) Identify differences in the individual, assault, and assailant characteristics for JDR victims, JDR converters, and victims who immediately notify the police ; (3) Understand the limitations and benefits of JDR policy from the perspective of Forensic Nurse Examiners (FNEs); (4) Explore potential modifications for JDR to improve the number of JDR victims who convert their case to police involvement. Methods: The study was a 2-phase exploratory study with a sequential design. The quantitative analysis included bivariate statistics and logistic regression on data collected from forensic records. Data for the qualitative analysis was collected from interviews with FNEs and was analyzed using premises of grounded theory. Results: The bivariate analysis demonstrated that JDR victims were more likely to experience a drug-facilitated sexual assault when compared to other victim groups. The multivariate analysis demonstrated that weapon use, victim resistance, race, and genital injuries are significant predictors of police reporting. The qualitative analysis identified 3 central themes: (1) Benefits of the JDR policy results in  Victim Empowerment ; (2) Limitations of the JDR policy creates Negative Consequences for Victims and Society ; and (3) Proposed modifications to JDR increase the potential for  Informed Decision Making  of sexual assault victims. Conclusion: JDR victims experience significantly different types of sexual assaults when compared to victims who immediately notified police. Considering the nature of sexual assaults experienced by JDR victims, it is unlikely police notification would occur without the JDR policy. Despite noted benefits of the JDR policy, modifications are needed to ensure victims are able to make informed decisions regarding evidence collection and police involvement following a sexual assault.

description: The theory of resonant generation of nonground-state Bose-Einstein condensates is extended to Bose-condensed systems at finite temperature. The generalization is based on the notion of representative statistical ensembles for Bose systems with broken global gauge symmetry. Self-consistent equations are derived describing an arbitrary nonequilibrium nonuniform Bose system. The notion of finite-temperature topological coherent modes, coexisting with a cloud of noncondensed atoms, is introduced. It is shown that resonant generation of these modes is feasible for a gas of trapped Bose atoms at finite temperature.

description: The design of cryptographic protocols with well understood properties is a difficult problem. Many simple cryptographic protocols that have been designed over the years by experienced designers have been found to have subtle flaws that have lead to attacks against them. As a result, designers will often attempt to modify protocols that have well understood properties to address new requirements. Such an approach can introduce flaws into the new protocol that are not present in the original protocol as assumptions under which the original protocol was designed are changed. In this paper, we will look at the issues associated with modifying two party authentication protocols to address group authentication by looking at efforts to modify the Needham-Schroeder-Lowe (NSL) protocol for use in group authentication. We will carefully review the assumptions under which the NSL protocol was proven to provide authentication and the changing assumptions when moving from a two party setting to a group setting. Several approaches to modifying the NSL protocol will be analyzed and flaws that result in the new protocols will be exposed, as well as approaches that maintain the properties of the protocol. Finally, we develop the requirements that any group authentication protocol would need to meet the same authentication goals as the NSL protocol against the same Dolev-Yao intruder.

description: In order to examine the characteristics of individuals who transition from nursing homes to the community, a group of 11,560 Medicaid participants aged 65 and older who had a nursing home admission between April 1, 2003, and April 1, 2006, were selected. Overall 231 of them transitioned to community; nearly three quarters of transitioned individuals wished to return to the community and over half had a support person who was positive toward discharge. Compared to all residents in the study, those who transitioned to the community were more likely to be younger, had a much lower average level of care, were in their Medicaid eligibility span for less than one year when they entered the nursing home, and were more likely to need lower levels of assistance with their activities of daily living.   A Heckman selection model was used in order to determine if any factors exist that can identify nursing home residents who are most likely to transition to stable living in the community. The model found that there were several known factors that can predict transition from a nursing home to the community, including age, gender, marital status, level of care, preference to return to the community, and the presence of a support person positive toward discharge. The second stage of the model, however, failed to find any factors significantly associated with an individual being stable in the community, suggesting that post-transition episodes (such as a heart attack or fall), not pre-transition characteristics, are responsible for truncated community living. Finally, an endogenous switching regression was used to determine how much Medicaid cost savings is associated with transitioning to the community, and how that cost savings is affected by individual characteristics. By comparing transitioned individuals to a matched group of nursing home residents, this study reaffirmed prior findings that transitioning older adults from a nursing home to the community is associated with Medicaid cost savings, in this case of approximately $1,900 per month. In addition, the findings show that there is a known factor--pre-transition cost--that has a significant effect on post-transition Medicaid spending.

description: We present partial-correlation analyses that examine the strengths of the relationships between L_UV, L_X, Alpha_OX, and redshift for optically-selected AGNs. We extend the work of Strateva et al. (2005), that analyzed optically-selected AGNs from the Sloan Digital Sky Survey (SDSS), by including 52 moderate-luminosity, optically-selected AGNs from the COMBO-17 survey with corresponding deep (~250 ks to 1 Ms) X-ray observations from the Extended Chandra Deep Field-South. The COMBO-17 survey extends ~3 magnitudes deeper than the SDSS and probes the moderate-luminosity AGNs that numerically dominate the AGN population in the Universe. We also include recently published observations of 19 high-redshift, optically-selected AGNs, and 46 luminous, low-redshift AGNs from the Bright Quasar Survey. The full sample used in our analysis consists of 333 AGNs, extending out to z~6, with 293 (88%) having X-ray detections. The sample spans five decades in UV luminosity and four decades in X-ray luminosity. We confirm that Alpha_OX is strongly anti-correlated with L_UV (13.6 sigma), the highest significance found for this relation to date, and find evidence suggesting that the slope of this relation may be dependent on L_UV. We find that no significant correlation exists between Alpha_OX and redshift (1.3 sigma), and constrain the maximum evolution of AGN UV-to-X-ray flux ratios to be less than 30% (1 sigma) out to z=5. Using our sample's high X-ray detection fraction, we also find a significant anti-correlation (3.0 sigma) between Alpha_OX and L_X . We make comparisons to earlier studies on this topic and discuss implications for X-ray vs. optical luminosity functions.

description: We have shown the generation/amplification of fast macro-scale plasma flows in the degenerate two-fluid astrophysical systems with initial turbulent (micro--scale) magnetic/velocity fields due to the Unified Reverse Dynamo/Dynamo mechanism. This process is simultaneous with and complementary to the micro-scale unified dynamo. It is found that the generation of macro--scale flows is an essential consequence of the magneto-fluid coupling; the generation of macro--scale fast flows and magnetic fields are simultaneous, they grow proportionately. The resulting dynamical flow acceleration is directly proportional to the initial turbulent magnetic (kinetic/magnetic) energy in degenerate e-i (degenerate e-p) astrophysical plasma; the process is very sensitive to both the degeneracy level of the system and the magneto-fluid coupling. In case of degenerate e-p plasma, for realistic physical parameters, there always exists such a real solution of dispersion relation for which the formation of strong macro-scale flow/outflow is guaranteed; the generated/accelerated locally super-Alfvénic flows are extremely fast with Alfvén Mach number $> 10^3$ as observed in a variety of astrophysical outflows

description: In this pilot study, we examine molecular jets from the embedded Class I sources, HH 26 and HH 72, to search, for the first time, for kinematic signatures of jet rotation from young embedded sources.High resolution long-slit spectroscopy of the H2 1-0 S(1) transition was obtained using VLT/ISAAC, position-velocity (PV) diagrams constructed and intensity-weighted radial velocities transverse to the jet flow measured. Mean intensity-weighted velocities vary between vLSR ~ -90 and -65 km/s for HH 26, and -60 and -10 km/s for HH 72; maxima occur close to the intensity peak and decrease toward the jet borders. Velocity dispersions are ~ 45 and ~ 80 km/s for HH 26 and HH 72, respectively, with gas motions as fast as -100 km/s present. Asymmetric PV diagrams are seen for both objects which a simple empirical model of a cylindrical jet section shows could in principle be reproduced by jet rotation alone. Assuming magneto-centrifugal launching, the observed HH 26 flow may originate at a disk radius of 2-4 AU from the star with the toroidal component of the magnetic field dominant at the observed location, in agreement with magnetic collimation models. We estimate that the kinetic angular momentum transported by the HH 26 jet is ~ 2E5 M_sun/yr AU km/s. This value (a lower limit to the total angular momentum transported by the flow) already amounts to 70% of the angular momentum that has to be extracted from the disk for the accretion to proceed at the observed rate. The results of this pilot study suggest that jet rotation may also be present at early evolutionary phases and supports the hypothesis that they carry away excess angular momentum, thus allowing the central protostar to increase its mass.
