Montagne des Français has been relatively well collected (P. Lowry <i>pers. comm.</i>), so the dearth of collections suggests this species is rare, even there. Its apparent rarity could also, at least in part, reflect it being quite inconspicuous and thus easily overlooked. The EOO could not be calculated, and its AOO is estimated to be 8 km 2. Montagne des Français is a category V protected area (Dudley 2008), but the habitat is somewhat threatened by wood-cutting, primarily for charcoal, but mainly on its lower slopes, below the altitude where <i>A. gillespieae</i> is found. <i>Acalypha gillespieae</i> is assigned a preliminary conservation status of Critically Endangered: CR B2ab(ii,iii,iv).</p> <p> MATERIAL EXAMINED. — 3 collections. <b>Madagascar</b>: <i>Gillespie, L. 4097</i> (ILLS, MO, P[P00324524], TAN), <i>10692</i> (CAN, MO, P, TAN), <i>10693</i> (CAN, K, MO, P, TAN).</p> <p>DESCRIPTION</p> <p> Shrubs, deciduous, to 3 m tall, intricately branched, monoecious. <b>Branches</b> densely pubescent with simple, short, straight, antrorsely appressed trichomes proximally and antrorsely curved trichomes distally, glabrescent when mature. <b>Axillary buds</b> spherical, <i>c.</i> 2 mm diameter, perulate, perules 2, imbricate, chartaceous, brownish, glabrous. <b>Stipules</b> to 2-3.5 mm long, subulate, densely pubescent with simple, short, spreadingascending trichomes. <b>Petioles</b> slender, 2-5 mm long, densely pubescent with simple, curved, antrorse trichomes. <b>Leaf blades</b> 1.5-4 × 1-3 cm, elliptic to obovate, membranous, unlobed or (2-)3-lobed; <b>base</b> rounded to broadly obtuse; <b>apex</b> obtuse; <b>margin</b> crenate, teeth rounded; <b>upper surface</b> sparsely pubescent with simple, straight, erect to antrorse trichomes; <b>lower surface</b> indumentum similar to that on upper surface but denser; venation somewhat prominent on both surfaces, actinodromous,, basal veins 3, secondary veins 2-3 per side. <b>Stipels</b> absent. <b>Inflorescences</b> spiciform, androgynous, axillary, <i>c.</i> 1 cm long, mostly male with 1 female bract at base; peduncle thin, 2-3 mm long, it and rachis densely pubescent with curved, antrorse trichomes. <b>Female segment: bract</b> 1, sessile, enlarging in fruit to 5 × 9 mm, subreniform, sparsely pubescent with simple, straight, antrorse trichomes; margin entire; <b>bracteoles</b> absent. <b>Male segment</b> persistent, to 3.5 mm long; flowers glomerate; bracts to 0.3 mm long, triangular, densely pubescent with simple, slender, flexuous trichomes. <b>Male flowers</b>: pedicel to 0.4 mm, glabrous; buds not seen. <b>Female flowers</b> 1 per bract, sessile; <b>sepals</b> 3, <i>c.</i> 0.75 mm long, rounded-deltate, ciliate with simple, slender, flexuous trichomes to 0.5 mm long; <b>ovary</b> not seen; <b>styles</b> 3, <i>c.</i> 2 mm long, slightly connate at base, rachis stout, pubescent with simple, short, straight, antrorse trichomes, each style divided into 5-8 segments. <b>Allomorphic flowers</b> not seen. <b>Capsules</b> to 3 mm diameter, echinate, projections conical, to 0.75 mm long, surface hispid with simple, straight, erect to antrorse trichomes to 0.5 mm long. <b>Seeds</b> 2 × 1.5 mm, pyriform, smooth.</p>Published as part of <i>Muñoz, Iris Montero, Levin, Geoffrey A. & Cardiel, José María, 2023, Monograph of Acalypha L.

"The Consolidated Assistance Program, Reforming Welfare by Synchronizing Public Assistance Benefits"
No full textLevin-Waldman examines the structure of existing welfare programs and concludes that the current array of benefits could be synchronized and consolidated to create a new system that would provide economic incentives to work. He suggests combining elements of the earned income tax credit (EITC) and current welfare programs into one program, a consolidated assistance program (CAP). Levin-Waldman argues that a program composed of an assistance component (with one set of benefits for working parents and a different set for nonworking parents) and a child support component could be designed to assure minimal subsistence to those unable to work while providing incentives for those on welfare to work without, in effect, penalizing them for getting off welfare. Such a program would reform welfare more expeditiously than a plan that would simply expand the EITC or put a time limit on welfare benefits. Moreover, such a plan would not necessarily add to the national budget deficit.

On limestone. Altitude <i>c.</i> 360 m (Fig. 22).</p> <p> PRELIMINARY CONSERVATION ASSESSMENT. — <i>Acalypha cardielii</i> is only known from one collection from the Tsingy de Bemaraha. Its EOO could not be calculated; its AOO is estimated to be 8 km 2. The Tsingy de Bemaraha lies within a national park and a nature reserve that have been IUCN category II and Ia protected areas since 1927, and a UNESCO World Heritage Site since 1990. The forest of this area has local anthropogenic pressures such as fire associated with the renewal of zebu (cattle) pastures, logging for construction, and deforestation for new agricultural lands, resulting in loss of forest cover during the last decade (Dudley 2008; Goodman <i>et al.</i> 2018). No specimens of this species have been collected for 88 years, so we cannot rule out that this species has become extinct. In conclusion, due to habitat loss, the restricted geographic range, and the absence of recent collections, <i>A. cardielii</i> is assigned a preliminary conservation status of Critically Endangered: CR B2ab(ii,iii) (probably EX).

Spectral Sparsification in the Semi-Streaming Setting
No full textLet G be a graph with n vertices and m edges. A sparsifier of G is a sparse graph on the same vertex set approximating in some natural way. It allows us to say useful things about while considering much fewer than m edges. The strongest commonly-used notion of sparsification is spectral sparsification; H is a spectral sparsifier of G if the quadratic forms induced by the Laplacians of G and H approximate one another well. This notion is strictly stronger than the earlier concept of combinatorial sparsification.
In this paper, we consider a semi-streaming setting, where we have only ~O(n) storage space, and we thus cannot keep all of G. In this case, maintaining a sparsifier instead gives us a useful approximation to G, allowing us to answer certain questions about the original graph without storing all of it. In this paper, we introduce an algorithm for constructing a spectral sparsifier of G with O(n log n/epsilon^2) edges (where epsilon is a parameter measuring the quality of the sparsifier), taking ~O(m) time and requiring only one pass over G. In addition, our algorithm has the property that it maintains at all times a valid sparsifier for the subgraph of G that we have received.
Our algorithm is natural and conceptually simple. As we read edges of we add them to the sparsifier . Whenever gets too big, we resparsify it in time. Adding edges to a graph changes the structure of its sparsifier's restriction to the already existing edges. It would thus seem that the above procedure would cause errors to compound each time that we resparsify, and that we should need to either retain significantly more information or reexamine previously discarded edges in order to construct the new sparsifier. However, we show how to use the information contained in to perform this resparsification using only the edges retained by earlier steps in nearly linear time
G Tolerance During Open- vs. Closed-Loop G-Time Control
No full textBACKGROUND: +Gz tolerance is traditionally determined in centrifuges with open-loop G control, i.e., the centrifuge is under operator control (open loop), and thus the test subject is unable to influence the Gz load. In modern centrifuges, however, the subject is commonly able to continuously control the Gz load (closed loop). It is a widespread opinion among fighter pilots that +Gz tolerance is higher under closed- than open-loop G control. The aims were to investigate whether +Gz tolerance is higher in closed- than open-loop G control, and whether it is possible to use closed-loop G control during precise determination of +Gz tolerance.METHODS: Relaxed +Gz tolerance was determined in eight men during rapid Gz-onset rate (ROR) under three conditions: 1) OL-VFB, open loop with visual feedback; 2) OL-NFB, open loop with no visual feedback; and 3) CL, closed loop. Straining +Gz tolerance was determined in 10 men during ROR in OL and CL conditions.RESULTS: Relaxed +Gz tolerance did not differ between CL (3.66 Gz), OL-VFB (3.70 Gz) and OL-NFB (3.64 Gz). Straining +Gz tolerance was similar in the CL (8.5 Gz) and OL (8.6 Gz) conditions. In the CL condition, the Gz load varied substantially and was on average lower than in the OL conditions, at any stipulated G-time profile.DISCUSSION: There is no systematic difference in relaxed or straining +Gz tolerance as determined in closed- vs. open-loop G-controlled systems. During closed-loop control, precision and reproducibility are too low to recommend it for accurate determination of relaxed G tolerance.Grönkvist M, Levin B, Eiken O.
