Raia durbanensis von Bonde & Swart, 1923: 11, fig. 1, pl. 22. Syntypes: (2) whereabouts unknown. Type locality: Hondeklip Bay, southwestern South Africa, southeastern Atlantic.
Local synonymy: Raia durbanensis: von Bonde & Swart, 1923: 11, fig. 1, pl. 22; Barnard, 1925: 69. Cruriraja durbanensis: Bigelow & Schroeder, 1948a: 550; Bigelow & Schroeder, 1953: 315; Bigelow & Schroeder, 1962: 199; Smith, 1964: 287; Wallace, 1967a: 7; Hulley, 1970: 156, fig. 3; Hulley, 1986: 116, fig. 25.2; Compagno et al., 1989: 84, pl.

Raia spinacidermis: Smith, 1949a: 66 (in part Raia durbanensis in synonymy); Smith, 1965: 66 (in part).)
South Africa voucher material: Syntypes, 2 specimens both lost. No other known specimens available.
South African distribution: Endemic. Hondeklip Bay (NC).
Remarks: The only two known specimens are lost and to date no other specimens of this species have been observed despite extensive surveys along the west coast. The specific name “ durbanensis ” is misleading since the only known specimens were caught off the west coast in very deepwater.
Conservation status: DD (2019).

South Africa voucher material: BMNH 1935.7. 14.1 (1) (several syntypes C. parcomaculata). SAIAB [former RUSI] 50 (Paratype of C. triangularis), SAIAB 10092, SAIAB 10094, SAIAB 10095, SAIAB 10096, SAIAB 10097, SAIAB 188326, SAIAB 188974, SAIAB 189239.
South African distribution: Occurs from Durban north to the KZN border with Mozambique.
Remarks: A very small skate with a limited range from about Durban to southern Mozambique. It has a complicated taxonomic history due to it being described as C. triangularis (Smith, 1964) and most subsequent authors referring to the Eastern and Western Cape form as C. parcomaculata. The issue was resolved by Aschliman et al. (2010) who concluded that C. triangularis is a junior synonym of C. parcomaculata.

description: The US leadership in science and technology has greatly benefitted from immigrants from other countries, most notably from China in the recent decades. However, feeling the pressure of potential federal investigation since the 2018 launch of the China Initiative under the Trump administration, Chinese-origin scientists in the US now face higher incentives to leave the US and lower incentives to apply for federal grants. Analyzing data pertaining to institutional affiliations of more than 2.3 million scientific papers, we find a steady increase in the return migration of Chinese-origin scientists from the US back to China. We also conducted a survey of Chinese-origin scientists employed by US universities in tenure or tenure-track positions (n=1300), with results revealing general feelings of fear and anxiety that lead them to consider leaving the US and/or stop applying for federal grants.

Differential diagnosis.
This species is similar to B. lakainguta, B. multihami, and B. hooki, but differs from all by the presence of spiral striation on the shell and absence of hooked apertural barriers. Bensonella karoensis is also not spirally striated, is more ovoid with a blunter apex and shallower suture. See also under B. spinosa sp. nov.
Distribution.
SW and SE Himalaya.

Preserving privacy with PATE for heterogeneous data
Creators: name: Dodwadmath, Akshay

Publisher: name: CISPA
Year: 2023

description: Differential privacy has become the standard system to provide privacy guarantees for user data in machine learning models. One of the popular techniques to ensure privacy is the Private Aggregation of Teacher Ensembles (PATE) framework. PATE trains an ensemble of teacher models on private data and transfers the knowledge to a student model, with rigorous privacy guarantees derived using differential privacy. So far, PATE has been shown to work assuming the public and private data are distributed homogeneously. We show that in the case of high mismatch (non iid-ness) in these distributions, the teachers suffer from high variance in their individual training updates, causing them to converge to vastly different optimum states. This leads to lower consensus and accuracy for data labelling. To address this, we propose a modification to the teacher training process in PATE, that incorporates teacher averaging and update correction which reduces the variance in teacher updates. Our technique leads to improved prediction accuracy of the teacher aggregation mechanism, especially for highly heterogeneous data. Furthermore, our evaluation shows our technique is necessary to sustain the student model performance, and allows it to achieve considerable gains over the original PATE in the utility-privacy metric.

description: We investigate the Berezinskii-Kosterlitz-Thouless (BKT) transition in a semiconductor-superconductor two-dimensional Josephson junction array. Tuned by an electrostatic top gate, the system exhibits separate superconducting (S), anomalous metal (M*), and insulating (I) phases, bordered by separatrices of the temperature-dependent of sheet resistance, $R_{s}$. We find that the gate-dependent BKT transition temperature falls to zero at the S-M* boundary, suggesting incomplete vortex-antivortex pairing in the M* phase. In the S phase, $R_{s}$ is roughly proportional to perpendicular magnetic field at the BKT transition, as expected, while in the M* phase $R_{s}$ deviates from its zero-field value as a power-law in field with exponent close to 1/2 at low temperature. An in-plane magnetic field eliminates the M* phase, leaving a small scaling exponent at the S-I boundary, which we interpret as a remnant of the incipient M* phase.

description: We study the $K$-ring of the wonderful variety of a hyperplane arrangement and give a combinatorial presentation that depends only on the underlying matroid. We use this combinatorial presentation to define the $K$-ring of an arbitrary loopless matroid. We construct an exceptional isomorphism, with integer coefficients, to the Chow ring of the matroid that satisfies a Hirzebruch--Riemann--Roch-type formula, generalizing a recent construction of Berget, Eur, Spink, and Tseng for the permutohedral variety (the wonderful variety of a Boolean arrangement). As an application, we give combinatorial formulas for Euler characteristics of arbitrary line bundles on wonderful varieties. We give analogous constructions and results for augmented wonderful varieties, and for Deligne--Mumford--Knudsen moduli spaces of stable rational curves with marked points.

Smith (1957e) also described it as a new species, D. lubricus, from off Algoa Bay, but both these species were synonymized by Wallace (1967c) as D. thetidis, which was long considered valid until Last et al. (2016h) revised the family and concluded that it is Bathytoshia lata, a wide-ranging species of large stingray found in the Indo-Pacific and Eastern Atlantic, including the Mediterranean Sea.
Conservation status: NE.

description: We prove that the mapping class group of the one-holed Cantor tree surface is acyclic. This in turn determines the homology of the mapping class group of the once-punctured Cantor tree surface (i.e. the plane minus a Cantor set), in particular answering a recent question of Calegari and Chen. We in fact prove these results for a general class of infinite-type surfaces called binary tree surfaces. To prove our results we use two main ingredients: one is a modification of an argument of Mather related to the notion of dissipated groups; the other is a general homological stability result for mapping class groups of infinite-type surfaces.

description: The study determined the effect of cloud accounting cost on financial performance of Nigerian deposit banks. Specifically, the study ascertained; the relationship between server maintenance cost and return on assets of Nigerian deposit money banks; the relationship between software acquisition cost and return on assets of Nigerian deposit money banks, and the relationship between cost of training and return on assets of Nigerian deposit money banks. Ex-Post Facto research was employed by the study. A sampled of five deposit money banks was used for the study. Data were extracted from the annual accounts of the sampled banks from 2012 to 2022. The data were analyzed and tested with multiple regression analysis via E-view 9.0. The results revealed that server maintenance cost and cost of training have positive effect on financial performance but this effect were not significant while software acquisition cost has negative and insignificant effect on financial performance of deposit money banks in Nigeria. Based on the findings, the study recommended among others that there is a compelling need for the government to enact a law to protect cloud data and ensure its seamless utilization. Reduce the cost of data and accessories this will act as incentive to many organizations to key into the new technology.

description: Product Creation (PC) refers to the process of planning and developing a product as well as related services from the initial idea until manufacturing and distribution. Throughout this process, there are numerous tasks that depend on human expertise and are typically undertaken by experienced practitioners. As the field of Artificial Intelligence (AI) continues to evolve and finds its way into the manufacturing sector, there exist many possibilities for an application of AI in order to assist in solving aforementioned tasks. In this work, we provide a comprehensive overview of the current state of the art of the use of AI in PC.
In detail, we analyze 40 existing surveys on AI in PC and 94 case studies in order to find out which areas of PC are primarily addressed by current research in this field, how mature the discussed AI methods are, and to which extent data-centric approaches are utilized in current research.

description: Industrial Control Systems (ICS) are responsible for the safety and operations of critical infrastructure such as power grids.
Attacks on such systems threaten the well-being of societies, and the lives of human operators, and pose huge financial risks.
Due to their reliance on insecure legacy protocols and hosts, the systems cannot be protected easily.
Fortunately, detailed process data is available and can be leveraged by process-aware attack detectors that verify inherent physical correlations.
In commercial products, such detectors will be trained by the vendors on process data from the target system, which might allow malicious manipulations of the training process to later evade detection at runtime.
Previously proposed attacks in this direction rely on detailed process knowledge to predict the exact attack features to be concealed.

In this work, we show that even without any process knowledge, it is possible to launch training time attacks against such attack detectors. Our backdoor attacks achieve this by identifying `alien' actuator state combinations that never occur in the training samples and injecting them with legitimate sensor data into the training set.
At runtime, the attacker spoofs one of those alien actuator state combinations, which triggers (regardless of current process sensor values) the classification as `normal'.

To demonstrate this, we design and implement five backdoor attacks against autoencoder-based anomaly detectors for 14 attacks from the BATADAL dataset collection. Out of these five variations, four implementations have been found to be effective. Our evaluation also shows that our best backdoor attack implementation can achieve perfect attack concealment and accomplish an average accuracy of 0.19.
Compared to the performance of the detector for anomalies that are not concealed by inserted triggers, our attacks decrease the detector's accuracy by 0.39.

description: The use of computer vision for product and assembly quality control is becoming ubiquitous in the manufacturing industry. Lately, it is apparent that machine learning based solutions are outperforming classical computer vision algorithms in terms of performance and robustness. However, a main drawback is that they require sufficiently large and labeled training datasets, which are often not available or too tedious and too time consuming to acquire. This is especially true for low-volume and high-variance manufacturing. Fortunately, in this industry, CAD models of the manufactured or assembled products are available. This paper introduces CAD2Render, a GPU-accelerated synthetic data generator based on the Unity High Definition Render Pipeline (HDRP). CAD2Render is designed to add variations in a modular fashion, making it possible for high customizable data generation, tailored to the needs of the industrial use case at hand. Although CAD2Render is specifically designed for manufacturing use cases, it can be used for other domains as well. We validate CAD2Render by demonstrating state of the art performance in two industrial relevant setups. We demonstrate that the data generated by our approach can be used to train object detection and pose estimation models with a high enough accuracy to direct a robot. The code for CAD2Render is available at https://github.com/EDM-Research/CAD2Render.

description: Multi-stage tournaments consisting of a round-robin group stage followed by a knockout phase are ubiquitous in sports. However, this format is incentive incompatible if at least two teams from a group advance to the knockout stage where the brackets are predetermined. A model is developed to quantify the risk of tanking in these contests. The suggested approach is applied to the 2022 FIFA World Cup to uncover how its design could have been improved by changing group labelling (a reform that has received no attention before) and the schedule of group matches. Scheduling is found to be a surprisingly weak intervention compared to previous results on the risk of collusion in a group. The probability of tanking, which is disturbingly high around 25\%, cannot be reduced by more than 3 percentage points via these policies. Tournament organisers need to consider more fundamental changes against tanking.

Remarks: This species was previously referred to as Himantura gerrardi, but it should be assigned to the genus Maculabatis. It is similar to M. ambigua, a species known presently from the Red Sea to Zanzibar, Tanzania, but may be distinct. It is currently under investigation. The common name is Baraka’s Stingray, but in South Africa it is known as the Sharpnose Stingray.
Conservation status: NE (2019).
