description: In molecular beam scattering experiments, an important technique for measuring product energy and angular distributions is velocity map imaging following photoionization. For studies with cold molecular beams, the resolution is often limited by the product detection process. When state-selective ionization detection is used, excess photon energy can transfer to kinetic energy in the molecular ion-electron pair, resulting in measurable cation recoil. With advanced molecular beam technology, velocity spreads as small as a few m/s are possible. Thus, a suitable product detection scheme must be not only sensitive, state-selective, and background-free, it must also produce less cation recoil than the velocity spread of the molecular beams. To date this has only been possible with the NO molecule. Our goal here is to extend this low-recoil capability to fully deuterated ammonia, ND$_3$. We present a resonance-enhanced multi-photon ionization (REMPI) detection scheme for ND$_3$, that imparts sufficiently low ion recoil, allowing, for the first time, high-resolution imaging of ND$_3$ products in a cold ND$_3$-HD scattering experiment. The first step of the 1+1$'$ REMPI scheme requires vacuum ultra-violet (VUV) photons of ~160 nm, which are generated through four-wave-mixing in Xe. We varied the wavelength of the second, ionization step between 434 and 458 nm, exciting ND$_3$ to a wide range of autoionizing neutral states. By velocity mapping the resulting photoelectrons, it was possible to fully chart the ion recoil across this range with vibrational resolution for the final ionic states. Additionally, rotational resolution in the photoionization dynamics was achieved for selected excitation energies near one of the vibrational thresholds. Many of the peaks in the spectrum of autoionizing Rydberg states are assigned to specific Rydberg series using a simple Rydberg formula model.

Etymology
Named for Tracey McVea, in acknowledgement of her tireless efforts as Grants and Research Support Officer at the Australian Museum Research Institute.
Material examined
Holotype. QM MO85999, Rifle Ck, c. 1 km NW of Mt Molloy, north-eastern Qld, Australia (15 57’ S, 145 19’ E), 10 September 1988, J. Stanisic, D. Potter.
Paratype. QM MO20694 (same data as holotype).
Other material. See Table 1.
Diagnosis
External morphology. Shell (Figure 6 (e)) small (SW 6.6 mm), golden amber, 5.2 whorls, subdiscoidal with a low conical spire, whorls rounded; umbilicus narrow; protoconch and teleoconch with fine spiral grooves. Body white (in alcohol). Mantle lobes moderately small; shell lappets long, triangular, tapering. Caudal horn moderately large.
Genital anatomy. Genitalia (Figure 12) with short vagina; bursa copulatrix of moderate length, duct broad, internally with fine, longitudinal, anastomosing ridges; bursa elongate. Penis short, slender, internally with two chambers, distal portion sculptured with one main longitudinal pilaster and a second, shorter and narrower pilaster; proximal portion sculptured with longitudinal ridges; penial verge absent;penis 100% enclosed in penial tunica.Epiphallus longer than penis, similar in width to penis; two arms of epiphallus approximately equal in length; long epiphallic caecum present, with basal attachment of the penial retractor muscle; flagellum moderately short, slender, coiled, without obvious internal cryptae.
Remarks
Geminitor mvceae (preliminarily identified as P. villaris ‘Rifle Creek’) is only known from the holotype and paratype, from Rifle Creek near Mt Molloy (Figure 4). This species was previously subsumed within G. villaris, which it closely resembles. However, G. macveae is significantly smaller than G. villaris, with a much smaller and narrower penis and distinctly different internal penial sculpture. It is the smallest and most southerly distributed of all Geminitor species.

Stochastic halfspace approximation method for convex optimization with nonsmooth functional constraints
Creators: name: Singh, Nitesh Kumar

Publisher: name: arXiv
Year: 2024
Subjects: subject: Optimization and Control (math.OC)
subject: FOS: Mathematics

description: In this work, we consider convex optimization problems with smooth objective function and nonsmooth functional constraints. We propose a new stochastic gradient algorithm, called Stochastic Halfspace Approximation Method (SHAM), to solve this problem, where at each iteration we first take a gradient step for the objective function and then we perform a projection step onto one halfspace approximation of a randomly chosen constraint. We propose various strategies to create this stochastic halfspace approximation and we provide a unified convergence analysis that yields new convergence rates for SHAM algorithm in both optimality and feasibility criteria evaluated at some average point. In particular, we derive convergence rates of order $\mathcal{O} (1/\sqrt{k})$, when the objective function is only convex, and $\mathcal{O} (1/k)$ when the objective function is strongly convex. The efficiency of SHAM is illustrated through detailed numerical simulations.

description: In social media, neural network models have been applied to hate speech detection, sentiment analysis, etc., but neural network models are susceptible to adversarial attacks. For instance, in a text classification task, the attacker elaborately introduces perturbations to the original texts that hardly alter the original semantics in order to trick the model into making different predictions. By studying textual adversarial attack methods, the robustness of language models can be evaluated and then improved. Currently, most of the research in this field focuses on English, and there is also a certain amount of research on Chinese. However, there is little research targeting Chinese minority languages. With the rapid development of artificial intelligence technology and the emergence of Chinese minority language models, textual adversarial attacks become a new challenge for the information processing of Chinese minority languages. In response to this situation, we propose a multi-granularity Tibetan textual adversarial attack method based on masked language models called TSTricker. We utilize the masked language models to generate candidate substitution syllables or words, adopt the scoring mechanism to determine the substitution order, and then conduct the attack method on several fine-tuned victim models. The experimental results show that TSTricker reduces the accuracy of the classification models by more than 28.70% and makes the classification models change the predictions of more than 90.60% of the samples, which has an evidently higher attack effect than the baseline method.

description: Otsuka (2023) argues for a correspondence between data science and traditional epistemology: Bayesian statistics is internalist; classical (frequentist) statistics is externalist, owing to its reliabilist nature; model selection is pragmatist; and machine learning is a version of virtue epistemology. Where he sees diversity, I see an opportunity for unity. In this article, I argue that classical statistics, model selection, and machine learning share a foundation that is reliabilist in an unconventional sense that aligns with internalism. Hence a unification under internalist reliabilism.

Material examined
Holotype. QM MO48601, Bellenden Ker Range, summit TV Stn, north-eastern Qld, Australia (17°03ʹS, 145°42ʹE), rainforest, 1560 m, 29 April 1983, G. Monteith, D. Yeates.
Paratypes. QM MO11240, QM MO48363, QM MO48374, QM MO78930.
Diagnosis
External morphology. Shell (Figure 22 (a)) medium-sized (SW 13.9–18 mm), amber, often darker below periphery, 5.3–5.7 whorls, trochoidal with a moderate spire, whorl profile strongly angulate; microsculpture of very fine spirals on protoconch and teleoconch; umbilicus very narrow. Body light brown with cream-coloured lappets (in alcohol). Mantle lobes small; shell lappets long, narrow, tapering. Caudal horn moderately large.
Genital anatomy. Genitalia (Figure 23) with moderately long vagina, internally with longitudinal ridges; bursa copulatrix moderately short, duct narrow, internally with longitudinal ridges; bursa elongate. Penis moderately small, tubular; internally with three longitudinal pilasters, two of them merging basally, internal wall sculptured with longitudinal wrinkles; penis and part of epiphallus enclosed in penial tunica. Epiphallus enters penis through a simple pore; epiphallus longer than penis; epiphallus 2 longer than epiphallus 1; epiphallic caecum absent; flagellum long, slender, without obvious internal cryptae, last third slightly swollen.
Remarks
Elatonitor montanus is known only from montane rainforest on Mt Bellenden Ker and Mt Bartle Frere, above 1200 m elevation. The only material available in the current study was from Mt Bellenden Ker (Figure 4). A close comparison with specimens from Mt Bartle Frere would be of benefit, as these populations are isolated from one another and it is possible that the Mt Bartle Frere population represents a separate species.
This species can be distinguished from its congener E. suturalis by its slightly smaller size and trochoidal shape; it can be distinguished from all other large helicarionid snails of northern Australia by its sharply angulate whorls.

description: We propose a new approach to visual perception for relative localization of agents within large-scale swarms of UAVs. Inspired by biological perception utilized by schools of sardines, swarms of bees, and other large groups of animals capable of moving in a decentralized yet coherent manner, our method does not rely on detecting individual neighbors by each agent and estimating their relative position, but rather we propose to regress a neighbor density over distance. This allows for a more accurate distance estimation as well as better scalability with respect to the number of neighbors. Additionally, a novel swarm control algorithm is proposed to make it compatible with the new relative localization method. We provide a thorough evaluation of the presented methods and demonstrate that the regressing approach to distance estimation is more robust to varying relative pose of the targets and that it is suitable to be used as the main source of relative localization for swarm stabilization.

Host: Bufo marinus (Linnaeus), cane toad (Anura; Bufonidae).
Locality: Jamaica. (Introduced)
Description: Based on one specimen: Body 1,768 by 806; forebody 520 long, representing 29% of body length. Mouth subterminal; oral sucker, oval, 220 by 221; prepharynx absent; pharynx oval, 83 by 99; ratio of pharynx width to oral sucker width 1:2.2; esophagus 98 long; ceca terminating well past posterior margin of ovary, occupying 28% of postovarian space. Ventral sucker oval, situated in posterior of anterior 1/3 of body, 160 by 170; ratio of ventral sucker width to oral sucker width 1:1.3. Testes slightly oblique; right testis 120 by 143; left testis 130 by 120. Genital pore median, located near posterior margin of pharynx. Cirrus sac 155 long, representing 9% of body length. Ovary oval, 140 by 130; postovarian space 990 long, representing 56% of body length. Uterus extensive, filling hindbody. Vitelline follicles distributed in lateral fields from posterior margin of oral sucker to level of ceca ends posteriorly. Eggs 35 (34–39) by 20 (18–22). Excretory system not visible.
Remarks: This specimen appears to have been overly compressed at the time of fixation: the shape of the body is distorted, the pharynx is twisted, the cecal bifurcation is displaced to the left, and the cirrus sac appears unusually wide.
Although this specimen has ceca that surpass the ovary posteriorly and a prebifurcal genital pore, the genital pore is median rather than submedian, precluding its assignment to the monas body type. Based on these characters, this specimen is assigned to the mesembrinum body type. This specimen further differs from M. monas by having vitelline fields that surpass the cecal ends posteriorly compared with terminating well short of cecal ends, a smaller forebody (520 compared with 970), a narrower oral sucker (221 compared with 382), a narrower pharynx (83 compared with 138), and a narrower ventral sucker (170 compared with 344).
This specimen is consistent with M. meggitti by having a prebifurcal genital pore that is located immediately posterior to the pharynx, a similar ratio of ventral sucker width to oral sucker width (1:1.3 compared with 1:1.3–1:1.5), a similar ratio of pharynx width to oral sucker width (1:2.2 compared with 1:2.0), a similar body length (1,768 compared with 1,070–2,110), and a similar egg length (34–39 compared with 33–37).

Host: Anolis sagrei (Dumeril & Bibron), brown anole (Squamata: Polychrotidae).
Locality: Sarasota, Florida. (Introduced)
Description: Based on one specimen: Body 2,050 by 640; forebody 676 long, representing 33% of body length. Mouth subterminal; oral sucker spherical, 203 by 213; prepharynx absent; pharynx spherical, 85 by 108; ratio of width of pharynx to width of oral sucker 1:2.1; esophagus 260 long; ceca terminating posterior to posterior margin of ovary, occupying 37% of postovarian space. Ventral sucker subspherical, situated posterior margin of anterior 1/3 of body, 163 by 185; ratio of ventral sucker width to oral sucker width 1:1.2. Testes oval to subspherical; left testis 135 by 125; right testis not visible. Genital pore submedian, located immediately posterior to midlevel of esophagus. Cirrus sac clavate, 200 long, representing 10% of body length. Ovary circular, 138 by 138; postovarian space 1,120 long, representing 55% of body length. Uterus extensive, filling hindbody. Vitelline follicles distributed in lateral fields from level of pharynx to near level of cecal ends posteriorly. Eggs 43 (40–45) by 25 (24–26). Excretory system I-shaped; Excretory pore terminal.
Remarks: This specimen appears to be rolled so that the gonads have become moved to the left. The poor quality of the specimen precluded observation of some structures (e.g. right testis).
Although this specimen has ceca surpassing the ovary posteriorly and a prebifurcal, submedian genital pore, and is assigned to the monas body type, it cannot be assigned specifically to M. monas. This specimen can be distinguished from M. monas by having vitelline fields that surpass the cecal ends posteriorly compared with terminating well short of the cecal ends (about the level of the anterior margin of the ovary), a shorter forebody (676 compared with 970), a narrower oral sucker (213 compared with 382), and a narrower ventral sucker (185 compared with 344).
This specimen is consistent with M. americanum by having a similar oral sucker width (213 compared with 208–360), a similar pharynx width (108 compared with 75–165), a similar ventral sucker width (185 compared with 125–238), a similar postovarian space length (1,120; 55% of the body length compared with 740–2,626; 62%), a similar cirrus sac length (200; 8% of the body length compared with 176; 8%), similar egg sizes (43 [40–45] by 25 [24–25] compared with 41 [39–45] by 24 [21–26]), and were collected from the same general geographical area (Texas compared with Florida).

description: The employment of stochastic geometry for the analysis and design of ultra dense networks (UDNs) has provided significant insights into network densification. In addition to the characterization of the network performance and behavior, these tools can also be exploited toward solving complex optimization problems that could maximize the capacity benefits arising in UDNs. However, this is preconditioned on the existence of tractable closed form expressions for the considered figures of merit. In this course, the present paper introduces an accurate approximation for the moment generating function (MGF) of the aggregate other-cell interference created by base stations whose positions follow a Poisson point process of given spatial density. Given the pivotal role of the MGF of the aggregate interference in stochastic geometry and the tractability of the derived MGF, the latter can be employed to substantially simplify ensuing stochastic geometry analyses. Subsequently, the present paper employs the introduced MGF to provide closed form expressions for the downlink ergodic capacity for the interference limited case, and validates the accuracy of these expressions by the use of extensive Monte Carlo simulations. The derived expressions depend on the density of users and base stations, setting out a densification road map for network operators and designers of significant value.

Locality: Mexico. (Native)
Description: Based on one specimen: Body 2,262 by 936; forebody 780 long, representing 34% of body. Mouth subterminal; oral sucker subspherical, 270 by 270; prepharynx absent; pharynx subspherical, 94 by 104; ratio of width of pharynx to width of oral sucker 1:2.6; esophagus 81 long; ceca surpassing ovary posteriorly, occupying 37 % of postovarian space. Ventral sucker subspherical, situated in anterior 1/3 of body, 172 by 187; ratio of ventral sucker width to oral sucker width 1:1.4. Testes spherical to subspherical, oblique; right testis 130 by 143; left testis 117 by 122. Genital pore, submedian, located immediately posterior to midlevel of esophagus. Cirrus sac 200 long, representing 9% of body length. Ovary subspherical, 220 by 200; postovarian space 1,274 long, representing 56% of body length. Uterus filling hindbody. Vitelline follicles distributed in lateral fields from level of oral sucker to level of cecal ends. Eggs 35 (34–39) by 20 (18–22). Excretory system not visible.
Remarks: The specimen is in poor condition and appears to have been cold fixed, likely without coverslip pressure. It is contracted, irregular in shape, and its body has been rolled so that the pharynx, oral sucker and cecal bifurcation are shifted to the left, displacing the oral sucker and genital pore to the right. The forebody is contracted pulling the oral sucker away from the anterior end.
Although this specimen has ceca that surpass the ovary posteriorly and a prebifurcal genital pore, and is assigned to the monas body type, it cannot be assigned specifically to M. monas. This specimen differs from M. monas by having vitelline fields that terminate near to the cecal ends compared with terminating well short of cecal ends, a smaller forebody (780 compared with 970), a narrower pharynx (104 compared with 138), a narrower ventral sucker (172 compared with 344), and a narrower oral sucker (270 compared with 382).
This specimen is consistent with M. americanum by having a submedian genital pore that is immediately anterior to the cecal bifurcation, a similar body length (2,262 compared with 1,325–4,038), a similar ratio of oral sucker width to pharynx width (1:2.6 compared with 1:2.2–1:2.7), a similar ratio of oral sucker width to ventral sucker width (1:1.4 compared with 1:1.5–1:1.7), and a similar of postovarian space length (1,274 compared with 740–2,626).

description: In conversational recommender systems (CRSs), conversations usually involve a set of items and item-related entities or attributes, e.g., director is a related entity of a movie. These items and item-related entities are often mentioned along the development of a dialog, leading to potential sequential dependencies among them. However, most of existing CRSs neglect these potential sequential dependencies. In this article, we first propose a Transformer-based sequential conversational recommendation method, named TSCR, to model the sequential dependencies in the conversations to improve CRS. In TSCR, we represent conversations by items and the item-related entities, and construct user sequences to discover user preferences by considering both the mentioned items and item-related entities. Based on the constructed sequences, we deploy a Cloze task to predict the recommended items along a sequence. Meanwhile, in certain domains, knowledge graphs formed by the items and their related entities are readily available, which provide various different kinds of associations among them. Given that TSCR does not benefit from such knowledge graphs, we then propose a knowledge graph enhanced version of TSCR, called TSCRKG. In specific, we leverage the knowledge graph to offline initialize our model TSCRKG, and augment the user sequence of conversations (i.e., sequence of the mentioned items and item-related entities in the conversation) with multi-hop paths in the knowledge graph. Experimental results demonstrate that our TSCR model significantly outperforms state-of-the-art baselines, and the enhanced version TSCRKG further improves recommendation performance on top of TSCR.

description: The paper is devoted to the analysis of the influence of the galactic bar on the nature of the orbital motion (chaotic or regular) of globular clusters in the central region of the Galaxy with a radius of 3.5 kpc, which are subject to the greatest influence of the bar. The sample includes 45 globular clusters. To form the 6D phase space required for integrating the orbits, the most accurate astrometric data to date from the Gaia satellite (Vasiliev, Baumgardt, 2021) were used, as well as new refined average distances (Baumgardt, Vasiliev, 2021). The orbits of the globular clusters were obtained both in an axisymmetric potential and in a potential including the bar. The following, most realistic, bar parameters were adopted: mass $10^{10} M_\odot$, semi-major axis length 5 kpc, bar axis rotation angle 25$^o$, angular rotation velocity 40 km s$^{-1}$ kpc$^{-1}$. The analysis of the chaoticity/regularity of the orbital motion in both potentials was carried out using one of the most effective methods, namely, the frequency method, which consists in calculating the drift of fundamental frequencies. As a result, the influence of the bar on the dynamics of each GC of the sample was assessed. It is established that 8 GCs changed regular dynamics to chaotic under the influence of the bar, and 9 GCs changed chaotic dynamics to regular one.

Locality: Panama. (Native)
Description: Based on two specimens: Body 923 (806–1,040) by 585 (572–598); forebody 245 long, representing 27% of body length (n=1). Mouth subterminal; oral subspherical, 216 (208–224) by 246 (216–276); prepharynx absent; pharynx (could not be measured); esophagus (could not be measured); ceca short, terminating near anterior margin of ovary (cecal ends not visible, but ceca do not surpass ovary). Ventral sucker subspherical, situated in anterior 1/3 of body, 148 (135–161) by 153 (120–182); ratio of ventral sucker width to oral sucker width 1:1.7 (1:1.5–1:1.8).Genital pore prebifurcal, median. Uterus extensive, filling hindbody. Vitelline follicles distributed in lateral fields from level of upper margin of oral sucker to posterior margin of ovary. Eggs 34 by 23 (n=1). Excretory system not visible.
Remarks: In both specimens the forebody was contracted, pulling the oral sucker to within in a few micrometers of the ventral sucker. The poor quality of these two specimens precluded some measurements and other observations (e.g. cecal ends, only one egg measureable, cirrus sac, testes, ovary).
These specimens have ceca that do not surpass the ovary posteriorly and have a prebifurcal, median genital pore and are assigned to the pesteri body type, and cannot be M. monas. These specimens further differ from M. monas by having a narrower oral sucker (246 compared with 382), a narrower ventral sucker (120–182 compared with 344); ceca that terminate at anterior margin of ovary compared with ceca that terminate past posterior margin of ovary, and vitelline fields that terminate past the posterior margin of ovary compared with vitelline follicles that terminate well short of cecal ends.
The condition of these specimens precluded identification at the species level; however, egg size and general body morphology suggest that these specimens represent M. pesteri. It should be noted that the holotype of M. pesteri was in similar poor condition and extremely contracted.

description: We propose an adaption of the multiple imputation random lasso procedure tailored to longitudinal data with unobserved fixed effects which provides robust variable selection in the presence of complex missingness, high dimensionality and multicollinearity. We apply it to identify social and financial success factors of microfinance institutions (MFIs) in a data-driven way from a comprehensive, balanced, and global panel with 136 characteristics for 213 MFIs over a six-year period. We discover the importance of staff structure for MFI success and find that profitability is the most important determinant of financial success. Our results indicate that financial sustainability and breadth of outreach can be increased simultaneously while the relationship with depth of outreach is more mixed.

description: Quantum error correction is an essential ingredient in the development of quantum technologies. Its subject is to investigate ways to embed quantum Hilbert spaces into a physical system such that this subspace is robust against small imperfections in the physical systems. This task is exceedingly complex: for one, this is due to the vast diversity of possible physical systems with different structure to use. For another, every physical setting also comes with its own imperfections that need to be protected against. Bred by the complexity of a technological ambition, research on quantum error correction has developed into a large field of research that ranges from engineering of small systems with a single photon to the creation of macroscopic topological phases of matter and models of complex emergent physics. A quintessential tool in quantum error correction is the stabilizer formalism, which tames quantum systems by enforcing symmetries. A Gottesman-Kitaev-Preskill (GKP) code is a stabilizer code that creates a logical subspace within an infinite dimensional Hilbert space by endowing it with translational symmetries. While in practice the infinitude of the Hilbert space, as well as the infinitude of the translational symmetry group are considered as obstacles for implementation, in theory these are precisely the features that make the theory of GKP codes particularly rich, well behaved and well-connected to fascinating topics in mathematics. The purpose of this thesis is to explore these connections: to understand the coding theoretic and practical properties of GKP codes, utilizing its rich mathematical foundation, and to provide a foundation for future research. Along this journey we discover -- through the looking glass of GKP codes -- how quantum error correction fits into a fabulous mathematical world and formulate a series of dreams about possible directions of research.
