Western Pacific: Japan (Boso Peninsula, Okinawa, Tokashiki-jima, and Kumejima) (Okuno & Fiedler 2010; De Grave et al. 2012); probably introduced to southwestern Atlantic: Brazil (Ceará, Rio Grande do Norte) (present study, see remarks below). Remarks. The material identified here as Lysmata lipkei can be separated from all other Brazilian / Atlantic species of Lysmata by the combination of the following morphological characters: (1) lateral antennular flagellum with the accessory branch bearing only one free article; (2) pterygostomial angle of the carapace produced into a small sharp tooth; (3) carpus of the second pereiopod subdivided into 29–32 joints (Fig. 10 C, F, J, K). The specimens from Ceará are morphologically undistinguishable from L. lipkei Okuno & Fiedler 2010 from southern Japan, a species nearly identical and possibly synonymous (see below) with L. dispar Hayashi, 2007 from western Australia (Hayashi 2007; Okuno & Fiedler 2010). According to Okuno & Fiedler (2010), L. lipkei is distinguishable from L. dispar by the “account of the length and form of the rostrum” (i.e. reaching the distal margin of the second article of the antennular peduncle and straight in L. lipkei vs. reaching distal margin of the first article and with slightly convex dorsal margin in L. dispar); the “armature of the antennular peduncle” (i.e. with a minute spinule on the third article in L. lipkei vs. without such a spinule in L. dispar); and the “articulation of the ischium of the second pereiopod” (i.e. with barely visible articles in L. lipkei vs. with clearly visible ones in L. dispar). The Brazilian specimens have a straight, not particularly curved rostrum, which is typically reaching at least to the middle of the second article of the antennular peduncle (Fig. 10 A, B), as in L. lipkei. The articulations on the second pereiopod ischium are clearly visible (Fig. 10 J, K), as in L. dispar. All Brazilian specimens also have a minute spiniform seta on the third article of the antennular peduncle, a presumed differential character between L. lipkei and L. dispar. The most-posterior tooth on the mid-line of the carapace has been figured with a well-marked articulation for both L. dispar and L. lipkei (cf. Hayashi 2007: fig. 2 a, b; Okuno & Fiedler 2010: fig. 1 C). However, in the Brazilian material and in the examined paratype of L. lipkei, this tooth appears to be fixed or may have at most a feeble articulation in its posterior half (Fig. 10 B). The carpi of the third and fourth pereiopods are furnished with small spiniform setae in all Brazilian specimens examined (Fig. 11 A, C). These setae were not illustrated or mentioned by Okuno & Fiedler (2010) in L. lipkei, but were confirmed to be present by examination of the paratype deposited in the OUMNH. Remarkably, the Brazilian specimens match the type specimens of L. lipkei in all details of the colour pattern (cf. Fig. 12 and Okuno & Fiedler 2010: fig. 4); the colour pattern of L. dispar remains unknown. Based on the absence of clear morphological differences between the Ceará material and the type material of L. lipkei from Japan, as well as great similarities in their colour patterns, the Brazilian specimens are tentatively assigned to L. lipkei. Due to the ambiguity and subtleness of characters used by Okuno & Fielder (2010) to separate L. lipkei from L. dispar, a possibility that L. lipkei may represent a junior synonym of L. dispar has to be seriously considered. However, a decision on the taxonomic status of L. lipkei is beyond the scope of the present study. The Brazilian material of L. lipkei may represent the second record of a presumably non-indigenous species of Lysmata Risso, 1816 in Brazil and the southwestern Atlantic. Lysmata vittata (Stimpson, 1860) was the first species of Lysmata reported as invasive in Brazil, after synonymization of L. rauli Laubenheimer & Rhyne, 2010, by Soledade et al. (2013). However, since the taxonomic identity of L. vittata remains unsettled, the identity of the Brazilian material reported as L. vittata by Soledade et al. (2013) also remains uncertain. Thus, both species of Lysmata supposed to be invasive on the Brazilian coast, viz. L. lipkei and L. vittata sensu Soledade et al. (2013), will need to be genetically compared to reliably identified Indo-West Pacific specimens of L. lipkei, L. dispar and L. vittata, respectively.Published as part of Pachelle, Paulo P.

Self-organization of Object Features Representing Motion Using Multiple Timescales Recurrent Neural Network
No full textAffordance theory suggests that humans recognize the environment based on invariants. Invariants are features that describe the environment offering behavioral information to humans. Two types of invariants exist, structural invariants and transformational invariants. In our previous paper, we developed a method that self-organizes transformational invariants, or motion features, from camera images based on robot's experiences. The model used a bi-directional technique combining a recurrent neural network for dynamics learning, namely Recurrent Neural Network with Parametric Bias (RNNPB), and a hierarchical neural network for feature extraction. The bi-directional training method developed in the previous work was effective in clustering the motion of objects, but the analysis did not give good segregation results of the self-organized features (transformational invariants) among different motion types. In this paper, we present a refined model which integrates dynamics learning and feature extraction in a single model. The refined model is comprised of Multiple Timescales Recurrent Neural Network (MTRNN), which possesses better learning capability than RNNPB. Self-organization result of four types of motions have proved the model's capability to create clusters of object motions. The analysis showed that the model extracted feature sequences with different characteristics for four object motion types
Dynamic properties of submicron circular permalloy dots -- Presentazione poster by R. Zivieri - Conferenza internazionale
No full textCircular dots of permalloy with appropriate aspect ratio can exhibit a vortex structure with
perpendicular magnetization at the core [1,2]. In this paper, the dynamic properties of some dots
with the above mentioned characteristics, have been
sistematically investigated by Brillouin light
scattering (BLS) from thermally excited spin waves.
Fig.1 shows the comparison between the BLS
spectrum of the continuous permalloy film and that
of circular dots with diameter of 0.2 micron,
recorded in the same experimental conditions.
These spectra give evidence of a marked
discretization of the spin wave spectrum in
agreement with the theoretical prediction of
Guslienko et al. [3]. In fact, instead of the peak
associated to Damon-Eshbach mode measured for
the continuous film, five well resolved peaks are
present on both sides of the spectrum of the
patterned sample. The dependence of the frequency
of these discrete modes on both the intensity of the
external applied field and the in-plane wavector has
been measured. The experimental frequencies have
been compared to those calculated according to the
model proposed in Ref.3. We show that in the
wavevector interval investigated, the frequency of
these discrete modes is dispersionless and the
frequency monotonously increases with the
intensity of the magnetic field. Similar results were
observed by Jorzick et al. in circular permalloy dots
with diameter of 1 and 2 micron.[4]

Lysmata lipkei Okuno & Fiedler 2010
No full textLysmata lipkei Okuno & Fiedler, 2010 Fig. 8 Lysmata lipkei Okuno & Fiedler 2010: 599, figs 1–4. Diagnosis Carapace with rostrum reaching to about middle of second antennular article, armed with 4–5 teeth on dorsal margin (including two postorbital ones) and 2–4 on ventral margin; antennal tooth welldeveloped; pterygostomial angle with small acute tooth. Antennule with stylocerite subacute, falling short of reaching to end of first antennular segment; lateral flagellum with accessory ramus consisting of short one-segmented finger-shaped article. Antenna with inferior tooth of basicerite strong; scaphocerite distinctly surpassing antennular peduncle, lateral margin slightly concave, distolateral tooth slightly overreaching blade; carpocerite small, not reaching to end of first antennular article. First pereiopod robust, chela with fingers bearing a narrow gap when closed, especially on proximal half. Second pereiopods unequal in size, longer one with 27–32 and shorter one with 23–27 carpal segments. Third pereiopod with merus armed with spinules on distal 0.6 of segment length; carpus unarmed; dactylus biunguiculate, ventral margin with two or three accessory spines, decreasing in size toward proximal margin (in case of having three accessory teeth, proximal one very small). Fifth pereiopod with merus armed with 1–3 spinules disto-ventrally. Pleon with three anterior pleura rounded antero- and postero-ventrally, fourth pleuron angled posteroventrally, fifth pleuron with small acute tooth postero-ventrally. Posterior margin of telson with small acute median projection and two pairs of spines, with mesial pair stronger and longer than lateral pair. Material examined MADAGASCAR • 1 hermaphrodite; southern Madagascar; 25°26.4′ S, 44°56.1′ E; depth 14–18 m; 29 May 2010; MNHN exped.; Atimo-Vatae; Stn. BS03; GenBank MW798243; MNHN-IU-2010-4898. Remarks Although the lateral flagella of the two antennules in the single studied specimen of L. lipkei from Madagascar are broken, all other morphological characters, as well as molecular data, are consistent with the description and variability provided by Okuno & Fiedler (2010), except for one character – the number of accessory spinules on the flexor margin of the biunguiculate dactyli of the last three pereiopods. In the original description, there are three accessory spinules decreasing in size proximally, while only two accessory spinules are seen in the material of the present study. This single difference can be interpreted as inter-population variation, as specimens of Japan and Madagascar are very close genetically. Distribution This is the seventh record of L. lipkei. After being originally described from Japan by Okuno & Fiedler (2010), reported again from Japan by De Grave et al. (2012), and subsequently reported from Singapore by Anker & De Grave (2016); this species, based on morphological and genetic data, was recorded from the south-western Atlantic Ocean, Brazil, and classified as alien there by Alves et al. (2018) as well two other records from Brazil (Pachelle et al. 2016, 2020). The present report on L. lipkei from Madagascar significantly extends its known Indo-West Pacific range to the south-west Indian Ocean.Published as part of Ashrafi, Hossein, Baeza, J.

Japanese foreign direct investment : recent trends, determinants, and prospects
No full textIn the late 1980s, Japan became the biggest source of foreign direct investment (FDI) in the world. The main beneficiaries of the rapid increase in investment flows were industrial countries, but the developing world (especially East Asia and Latin America) also received substantial inflows. In East Asia, the newly industrial economies (NIEs) of Hong Kong, Republic of Korea, Singapore, and Taiwan (China) were, at first, production bases for Japanese manufacturing in the 1970s and early 1980s. But in the late 1980s, these countries became new, expanding consumer markets, attracting huge Japanese investments in the tertiary (service) sector, while investments in manufacturing shrank rapidly because of rising labor costs. The Association of Southeast Nations (ASEAN) and China became Japan's new production base. In Latin America (mostly small Caribbean countries) Japan's focus is almost exclusively on tax havens. Globally, Japan's investments in the secondary (manufacturing) and service sectors of the major Latin American nations are only marginal. Japanese investment flows declined drastically after 1989, mostly because of the depressed global and domestic economy, after rapid asset price deflation in Japan. Hardest hit by the decline were the United States and Europe. Japanese FDI flows to developing countries also declined, but less. The biggest losers were the NIEs and the Caribbean tax havens. The biggest losers were the NIEs and the Caribbean tax havens. Japanese investments continued to grow in other Latin American countries and, even more, in the ASEAN and China. Japanese investors sharply reduced tertiary sector investments, primarily geared to maintaining or expanding markets. Investments in the secondary sector, making use of low-cost production, continued to expand. This trend is expected to continue in the near future, with FDI flows declining further, albeit more slowly. Low-wage production countries such as China and Indonesia will attract an increasing share. Investment to expand markets in the industrial countries and the NIEs are likely to decline. But medium-term prospects for Japanese FDI in developing countries are brighter, as economic recovery and continuing current account surpluses in Japan will lead to a resumption of active foreign investment by Japanese multinational corporations.Foreign Direct Investment,Environmental Economics&Policies,International Terrorism&Counterterrorism,Economic Theory&Research,Trade and Regional Integration

Host. The holotype from Hachijo-jima Island, Japan was associated with the soft coral Stereonephthea japonica Utinomi, 1954 (Octocarallia, Alcyonacea, Nephtheidae). The Indonesian specimen was collected from an unidentified nephtheiid soft coral, while the Australian specimen was collected from the soft coral Efflatounaria sp. (Octocarallia, Alcyonacea, Nephtheidae). Etymology. The species is named after its characteristic gibbous carapace; dosennus (Latin) for humpback. The standard Japanese name for this species is Marumi-kakure-moebi. Size. The largest collected specimen is an ovigerous female of pcl. 2.1 mm, tl. 10.5 mm. Distribution. The present material was collected in Izu Islands of Japan, Bali of Indonesia and Lizard Island, northern part of the Great Barrier Reef of Australia. The gibbous, abnormal “ Hippolyte commensalis ” female specimen reported in Holthuis (1995) from the Gulf of Aqaba, Red Sea, very likely belongs to A. dossena sp. nov.Published as part of Marin, Ivan, Okuno, Junji & Chan, Tin-Yam, 2011, On the " Hippolyte commensalis Kemp, 1925 " species complex (Decapoda, Caridea, Hippolytidae), with the designation of a new genus and description of two new species from the Indo-West Pacific, pp. 32-54 in Zootaxa 2768 on pages 34-39, DOI: 10.5281/zenodo.20674
