Set Membership with Non-Adaptive Bit Probes
No full textWe consider the non-adaptive bit-probe complexity of the set membership problem, where a set S of size at most n from a universe of size m is to be represented as a short bit vector in order to answer membership queries of the form "Is x in S?" by non-adaptively probing the bit vector at t places. Let s_N(m,n,t) be the minimum number of bits of storage needed for such a scheme. In this work, we show existence of non-adaptive and adaptive schemes for a range of t that improves an upper bound of Buhrman, Miltersen, Radhakrishnan and Srinivasan (2002) on s_N(m,n,t). For three non-adaptive probes, we improve the previous best lower bound on s_N(m,n,3) by Alon and Feige (2009)

The diagnostic characters of the species are reddish brown scutum, bifid aculeus tip, absence of acrostichal and anterior supra-alar setae. Later, Drew and Raghu (2002) described Bactrocera (Daculus) yercaudiae based on males collected from Yercaud, Tamil Nadu and Bangalore which responded to cue lure. Perusal of original description of the two species showed complete congruence of characters except costal band, which was mentioned as confluent with vein R 2+ 3 in Bactrocera digressa and slightly overlapping R in B. yercaudiae. Material mentioned above which were keyed out as Bactrocera yercaudiae were examined to confirm the identity. Examination of aculeus tip of the females revealed that it has a bifid aculeus and all the characters are in concordance with that of B. digressa except for a slightly overlapping costal band which might have been overlooked by Radhakrishnan (1999) because it is very faint beyond vein R 2+3. Hence we propose B. yercaudiae as a junior synonymn of B. digressa. Since all the Asian species in subgenus Daculus are aberrant Bactrocera s.str. and true Daculus are African, B. digressa is retained in subgenus Bactrocera (Copeland et al., 2004). As per ICZN rules, Bactrocera digressa Radhakrishnan is the valid name. Three females have been reared from fruits of Alangium lamarkii collected from Yercaud, Tamil Nadu and are deposited in BMNH (Ian M. White, pers. comm.)Published as part of David, K.

Platessa arborea C. Radhakrishnan, S. Sherly & B. Karthick 2022, sp. nov.
No full textPlatessa arborea C. Radhakrishnan, S. Sherly & B. Karthick sp. nov. (Figs 1–67, Fig. 9 represents the holotype) LM Description (Figs 1–60):—Valve elliptical with narrowly rounded apices. Raphe-sternum valve (RSV): Length: 6.5–9.5 µm, width: 3.5–4.5 µm, ratio length/width: 1.6–2.2 (n = 60). Axial area narrow and hardly discernible, visible only near center of the valve; central area nearly rectangular shape, bordered by 2–3 shorter striae frequently more widely spaced. Striae radiate throughout the valve, 22–24 in 10 µm. Raphe slightly filiform expanded proximal raphe endings. Sternum valve (SV): wide axial area, Length: 6.0–9.0 µm, width: 3.5–4.5 µm. Striae densely arranged 22–24 in 10 µm, parallel at centre, radiate towards apices. SEM Description (Figs 61–67):—Raphe-sternum valve (RSV): Externally, raphe filiform, slight curvature found near ends (Figs 61 & 63). Proximal raphe ends positioned in a broadened shallow groove, distal raphe located in the shallow groove with cone-shaped endings, and both ends slightly bend to the same side (Fig. 61). Striae mostly uniseriate; however found biseriate at 2–3 striae near apices. (Fig. 61). Areolae, apically slit-like throughout the valve, only at the center of the valve it is round-shaped towards axial area (Fig. 61). Internally, proximal raphe ends are strongly hooked, a very remarkable feature which is infrequent in other Platessa species, and its distal ends are curved on opposite sides, terminating in well-developed helictoglossae (Figs 64, 65). Striae lowered between raised virgae. Width of the interstriae is wider than the striae. Striae internally rectangular to round in shape and mostly covered with hymen (Figs 64, 65). An apparent depression is observed on the central nodule (Figs 64, 65). Sternum valve (SV), externally, axial area covered with several irregular shape depressions distributed on the surface of the valve (Fig. 62). Striae uniseriate, however, found biseriate at more than 10 striae near the valve mantle (Fig. 62). Interstriae is raised, and the width of striae is unequal (Fig. 62). Internally, axial area is flat and features are not easily visible (Fig. 66). Biseriate striae found near the mantle with hymenated areolae. Interstriae raised its width slightly more than the striae (Fig. 67). Holotype (designated here):—Slide #58/55, Sample #2878; deposited at the Diatom Collection, Agharkar Research Institute Herbarium (AHMA), Pune, India. Type locality:— INDIA, Sikkim, composite tree moss sample collected on 22 November 2019 on the way to Khecheopalri Lake, West Sikkim district (27.34829 °N, 88.19187 °E; elevation 1794 m a.s.l.) by Radhakrishnan Cheran. Etymology:—Named after the habitat (tree) on which it was found. In Latin, the tree is called an Arbor.Published as part of Sherly, Sheena, Radhakrishnan, Cheran & Karthick, Balasubramanian, 2022, Platessa arborea sp. nov.

Improved Explicit Data Structures in the Bit-Probe Model Using Error-Correcting Codes
No full textWe consider the bit-probe complexity of the set membership problem: represent an n-element subset S of an m-element universe as a succinct bit vector so that membership queries of the form "Is x ∈ S" can be answered using at most t probes into the bit vector. Let s(m,n,t) (resp. s_N(m,n,t)) denote the minimum number of bits of storage needed when the probes are adaptive (resp. non-adaptive). Lewenstein, Munro, Nicholson, and Raman (ESA 2014) obtain fully-explicit schemes that show that
s(m,n,t) = ((2^t-1)m^{1/(t - min{2⌊log n⌋, n-3/2})}) for n ≥ 2,t ≥ ⌊log n⌋+1 .
In this work, we improve this bound when the probes are allowed to be superlinear in n, i.e., when t ≥ Ω(nlog n), n ≥ 2, we design fully-explicit schemes that show that
s(m,n,t) = ((2^t-1)m^{1/(t-{n-1}/{2^{t/(2(n-1))}})}),
asymptotically (in the exponent of m) close to the non-explicit upper bound on s(m,n,t) derived by Radhakrishan, Shah, and Shannigrahi (ESA 2010), for constant n.
In the non-adaptive setting, it was shown by Garg and Radhakrishnan (STACS 2017) that for a large constant n₀, for n ≥ n₀, s_N(m,n,3) ≥ √{mn}. We improve this result by showing that the same lower bound holds even for storing sets of size 2, i.e., s_N(m,2,3) ≥ Ω(√m)
