Published: February 2019

Generating a description of an image is called image captioning. Image captioning requires recognizing the important objects, their attributes, and their relationships in an image. It also needs to generate syntactically and semantically correct sentences. Deep-learning-based techniques are capable of handling the complexities and challenges of image captioning. In this survey article, we aim to present a comprehensive review of existing deep-learning-based image captioning techniques. We discuss the foundation of the techniques to analyze their performances, strengths, and limitations. We also discuss the datasets and the evaluation metrics popularly used in deep-learning-based automatic image captioning.

Published: February 2019

Policy-based management of computer systems, computer networks and devices is a critical technology especially for present and future systems characterized by large-scale systems with autonomous devices, such as robots and drones. Maintaining reliable policy systems requires efficient and effective analysis approaches to ensure that the policies verify critical properties, such as correctness and consistency. In this paper, we present an extensive overview of methods for policy analysis. Then, we survey policy analysis systems and frameworks that have been proposed and compare them under various dimensions. We conclude the paper by outlining novel research directions in the area of policy analysis.
Scratchpad-Memory Management for Multi-Threaded Applications on Many-Core Architectures
Authors: Venkataramani Vanchinathan , Chan Mun Choon , Mitra Tulika
Published: February 2019

Contemporary many-core architectures, such as Adapteva Epiphany and Sunway TaihuLight, employ per-core software-controlled Scratchpad Memory (SPM) rather than caches for better performance-per-watt and predictability. In these architectures, a core is allowed to access its own SPM as well as remote SPMs through the Network-On-Chip (NoC). However, the compiler/programmer is required to explicitly manage the movement of data between SPMs and off-chip memory. Utilizing SPMs for multi-threaded applications is even more challenging, as the shared variables across the threads need to be placed appropriately. Accessing variables from remote SPMs with higher access latency further complicates this problem as certain links in the NoC may be heavily contended by multiple threads. Therefore, certain variables may need to be replicated in multiple SPMs to reduce the contention delay and/or the overall access time. We present Coordinated Data Management (CDM), a compile-time framework that automatically identifies shared/private variables and places them with replication (if necessary) to suitable on-chip or off-chip memory, taking NoC contention into consideration. We develop both an exact Integer Linear Programming (ILP) formulation as well as an iterative, scalable algorithm for placing the data variables in multi-threaded applications on many-core SPMs. Experimental evaluation on the Parallella hardware platform confirms that our allocation strategy reduces the overall execution time and energy consumption by

Published: February 2019

Low-density lipoprotein receptor-related protein 5 (LRP5) plays a vital role in bone formation and regeneration. In this study, we developed an injectable and sustained-release composite loading LRP5 which could gelatinize in situ. The sustained release of the composite and its efficacy in bone regeneration were evaluated. Sodium alginate, collagen, hydroxyapatite, and LRP5 formed the composite LRP5-Alg/Col/HA. It was found that the initial setting time and final setting time of LRP5-Alg/Col/HA containing 4% alginate were suitable for surgical operation. When the composite was loaded with 40 μg/mL LRP5, LRP5-Alg/Col/HA did not exhibit a burst-release behavior and could sustainably release LRP5 up to 21 days. Up to 18 days, LRP5 released from LRP5-Alg/Col/HA still present the binding activity with DKK1 (Wnt signaling pathway antagonist) and could increase the downstream β-catenin mRNA in bone marrow mesenchymal stem cells. Moreover, LRP5-Alg/Col/HA was found to significantly increase bone mineral density in the defect area after 6 weeks’ implantation of LRP5-Alg/Col/HA into the rats’ calvarial defect area. H&E staining detection demonstrated that LRP5-Alg/Col/HA could mediate the formation of a new bone tissue. Therefore, we concluded that Alg/Col/HA was a suitable sustained-release carrier for LRP5 and LRP5-Alg/Col/HA had a significant effect on repairing bone defects and could be a good bone regeneration material.

Published: February 2019

“Pit‐in‐pit” foundations, where the overall pit is divided into inner and outer pits, present a wide range of engineering problems and yet have received little detailed study. Among the many factors that affect the stability of a deep foundation pit, loading and rainfall are the two most important. Therefore, in this study, physical model experiments are carried out in the laboratory based on a pit‐in‐pit foundation that is typical of engineering applications in China, simulating the deformation of the system under different loading and rainfall flow conditions. Optical fibers along with constant resistance and large deformation (CRLD) bolts are adopted to collectively monitor the stress and strain inside the pit‐in‐pit foundation, assisted by fiber Bragg grating (FBG) displacement meters. The results of the monitoring show that the position of the inner pit relative to the outer pit has a strong influence on the stability of the outer pit. The side on which the inner pit is closest to the outer pit wall is the most prone to instability and should thus be reinforced. Comparison and analysis of monitoring results obtained with optical fibers and CRLD bolts allow a potentially dangerous slip surface to be identified, indicating the value of using this type of collective monitoring in deep foundation pits.

Published: February 2019

Background. Due to the technical difficulty, it is not common to close the pelvic peritoneum in laparoscopic abdominoperineal resection (LAPR) in China, which increases the risk of related complications. Permanent sigmoid colostomy is performed through the transperitoneal route conventionally in LAPR. This leads to the high occurrence of parastomal hernias and bowel obstructions. To prevent the complications and reduce surgical costs of LAPR, we performed some modifications for it. Methods. 38 patients diagnosed with low rectal cancer during July 2014 to July 2016 received LAPR with our modifications. First, the mobilization of the rectum and lymphadenectomy were identical to the classical routine method. Second, two sutures were performed on the pelvic peritoneum with the first to reduce the tension, followed by the second continuous suture to close the pelvic floor. Third, a tunnel was made between the parietal peritoneum and abdominal wall for the end sigmoid to pass through to finish the colostomy. Results. LAPR was performed on totally 38 patients successfully with no case transferring to open surgery. The follow-up period was from 1 month to 1 year. The mean operative time was 142.2 ± 16.5 min ranging from 100 min to 175 min. The mean hospital stay was 12.0 ± 1.5 days. No case underwent the reconstruction of stoma. There was not a single complication of LAPR with these two techniques that occurred to all 38 patients. Conclusion. We consider LAPR with our two techniques feasible and safe, which can be accepted quickly to improve the life quality of patients. Therefore, we suggest our procedures as the first choice during LAPR surgery. This trial is registered with trial registration number 2014028.

Neural Network with Confidence Kernel for Robust Vibration Frequency Prediction
Authors: Liu Jiantao , Yang Xiaoxiang , Zhu Mingzhu
Published: February 2019

Image-based measurement has received increasing attention as it can substantially reduce the cost of labor, measurement equipment, and installation process. Instead of using optical flow, pattern, or marker tracking to extract a displacement signal, in this study, a novel noncontact machine learning-based system was proposed to directly predict vibration frequency with high accuracy and good reliability by using image sequences acquired from a single camera. The performance of the proposed method was demonstrated through experiments conducted in a laboratory and under real-field conditions and compared with those obtained using a contacted sensor. The vibration frequency prediction results of the proposed method are compared with industry-level vibration sensor results in the frequency domain, demonstrating that the proposed method could predict the target-object-vibration frequency as accurately as an industry-level vibration sensor, even under uncontrollable real-field conditions with no additional enhancement or extra signal processing techniques. However, only the principal vibration frequency of a measurement target is predicted, and the measurement range is limited by the trained model. Nonetheless, if these limitations are resolved, this method can potentially be used in real engineering applications in mechanical or civil structural health monitoring thanks to the simple deployment and concise pipeline of this method.
Increased Perceptual and Motor Performance of the Arms of Elite Water Polo Players
Authors: Gardasevic Jovan , Akpinar Selcuk , Popovic Stevo , Bjelica Dusko
Published: February 2019

Background. It has been stated that long-term participation in sport training can influence the motor asymmetry of the arms with a decreased interlimb difference. However, whether this pattern is observable in different sports and with different variables, like perceptual performance, still needs to be tested. Therefore, we investigated if long-term sports participation might modify the motor and perceptual performance asymmetries of arms in water polo players. It was hypothesized that water polo players would perform with less interlimb asymmetry in comparison to nonathletes. Methods. Right-handed water polo players and nonathletes were tested on motor performance for both arms during a reaching task. Thirteen water polo players and thirteen nonathletes performed reaching movements under two experimental conditions: (a) right arm and (b) left arm. Velocity, accuracy, hand path deviation from linearity, and reaction time were calculated for each trial and for both arms. The potential interlimb differences in movement performance could be assessed by testing. Results. Consistent with the hypothesis, our findings showed that water polo players displayed substantially less asymmetry in the performance of accuracy and reaction time. Conclusions. These findings suggest that performance asymmetries of arms can be altered via intense long-term practice.
Stock Market Forecasting Using Restricted Gene Expression Programming
Authors: Yang Bin , Zhang Wei , Wang Haifeng
Published: February 2019

Stock index prediction is considered as a difficult task in the past decade. In order to predict stock index accurately, this paper proposes a novel prediction method based on S-system model. Restricted gene expression programming (RGEP) is proposed to encode and optimize the structure of the S-system. A hybrid intelligent algorithm based on brain storm optimization (BSO) and particle swarm optimization (PSO) is proposed to optimize the parameters of the S-system model. Five real stock market prices such as Dow Jones Index, Hang Seng Index, NASDAQ Index, Shanghai Stock Exchange Composite Index, and SZSE Component Index are collected to validate the performance of our proposed method. Experiment results reveal that our method could perform better than deep recurrent neural network (DRNN), flexible neural tree (FNT), radial basis function (RBF), backpropagation (BP) neural network, and ARIMA for 1-week-ahead and 1-month-ahead stock prediction problems. And our proposed hybrid intelligent algorithm has faster convergence than PSO and BSO.

Authors: Yang Xinlei , Wang Hailiang
Published: February 2019

Earth represents an ecological building material that is thought to reduce the carbon footprint at a point in its life cycle. However, it is very important to eliminate the undesirable properties of soil in an environmentally friendly way. Cement‐stabilized rammed earth, as a building material, has gradually gained popularity due to its higher and faster strength gain, durability, and availability with a low percentage of cement. This paper covers a detailed study of hollow compressed cement‐stabilized earth‐block masonry prisms to establish the strength properties of hollow compressed cement‐stabilized earth‐block masonry. The test results for masonry prisms constructed with hollow compressed cement‐stabilized blocks with two different strength grades and two earth mortars with different strengths are discussed.

Management of patients presenting to the Emergency Department with chest pain is continuously evolving. In the setting of acute coronary syndrome, the availability of high-sensitivity cardiac troponin assays (hs-cTn) has allowed for the development of algorithms aimed at rapidly assessing the risk of an ongoing myocardial infarction. However, concerns were raised about the massive application of such a simplified approach to heterogeneous real-world populations. As a result, there is a potential risk of underdiagnosis in several clusters of patients, including women, for whom a lower threshold for hs-cTn was suggested to be more appropriate. Implementation in clinical practice of sex-tailored cut-off values for hs-cTn represents a hot topic due to the need to reduce inequality and improve diagnostic performance in females. The aim of this review is to summarize current evidence on sex-specific cut-off values of hs-cTn and their application and usefulness in clinical practice. We also offer an extensive overview of thresholds reported in literature and of the mechanisms underlying such differences among sexes, suggesting possible explanations about debated issues.

The majority of non–small-cell lung cancer (NSCLC) cases are diagnosed at advanced stages, primarily because earlier stages of the disease are either asymptomatic or may be attributed to other causes such as infection or long-term effects from smoking. Therefore, early detection of NSCLC would likely increase response and survival rates due to timely intervention. Here, we utilize a novel approach based on whole genome–derived tiled peptide arrays to identify epitopes associated with autoantibody reactivity in NSCLC as a potential means for early detection. Arrays consisted of 2,781,902 tiled peptides representing 20,193 proteins encoded in the human genome. Analysis of 86 prediagnostic samples and 86 matched normal controls from a high-risk cohort revealed 48 proteins with three or more reactive epitopes in NSCLC samples relative to controls. Independent mass spectrometry analysis identified 40 of the 48 proteins in prediagnostic sera from NSCLC samples, of which, 21 occurred in the immunoglobulin-bound fraction. In addition, 63 and 34 proteins encompassed three or more epitopes that were distinct for squamous cell lung cancer and lung adenocarcinoma, respectively. Collectively, these data show that tiled peptide arrays provide a means to delineate epitopes encoded across the genome that trigger an autoantibody response associated with tumor development.

Significance:

This study provides a modality for early diagnosis of NSCLC for precision oncology that can be applied to other cancer types.
Immuno-oncological Efficacy of RXDX-106, a Novel TAM (TYRO3, AXL, MER) Family Small-Molecule Kinase Inhibitor

Published: February 2019

Expression of the TAM (TYRO3, AXL, MER) family of receptor tyrosine kinases (RTK) has been associated with cancer progression, metastasis, and drug resistance. In immune cells, TAM RTKs can dampen inflammation in favor of homeostatic wound-healing responses, thus potentially contributing to the evasion of cancer cells from immune surveillance. Here we characterize the small-molecule RXDX-106 as a selective and potent pan-TAM RTK inhibitor with slow dissociation kinetics and significant antitumor activity in multiple syngeneic tumor models. Expression of AXL and MER on both immune and tumor cells increased during tumor progression. Tumor growth inhibition (TGI) following treatment with RXDX-106 was observed in wild-type mice and was abrogated in immunodeficient mice, suggesting that the antitumor activity of RXDX-106 is, in part, due to the presence of immune cells. RXDX-106–mediated TGI was associated with increased tumor-infiltrating leukocytes, M1-polarized intratumoral macrophages, and activation of natural killer cells. RXDX-106 proportionally increased intratumoral CD8+ T cells and T-cell function as indicated by both IFNγ production and LCK phosphorylation (pY393). RXDX-106 exhibited its effects via direct actions on TAM RTKs expressed on intratumoral macrophages and dendritic cells, leading to indirect activation of other immune cells in the tumor. RXDX-106 also potentiated the effects of an immune checkpoint inhibitor, α-PD-1 Ab, resulting in enhanced antitumor efficacy and survival. Collectively, these results demonstrate the capacity of RXDX-106 to inhibit tumor growth and progression and suggest it may serve as an effective therapy against multiple tumor types.

Significance:

The pan-TAM small-molecule kinase inhibitor RXDX-106 activates both innate and adaptive immunity to inhibit tumor growth and progression, indicating its clinical potential to treat a wide variety of cancers.

Published: February 2019

Purpose:

To identify deregulated and inhibitory miRNAs and generate novel mimics for replacement nanomedicine for head and neck squamous cell carcinomas (HNSCC).

Experimental Design:

We integrated miRNA and mRNA expression, copy number variation, and DNA methylation results from The Cancer Genome Atlas (TCGA), with a functional genome-wide screen.

Results:

We reveal that the miR-30 family is commonly repressed, and all 5 members sharing these seed sequence similarly inhibit HNSCC proliferation in vitro. We uncover a previously unrecognized inverse relationship with overexpression of a network of important predicted target mRNAs deregulated in HNSCC, that includes key molecules involved in proliferation (EGFR, MET, IGF1R, IRS1, E2F7), differentiation (WNT7B, FZD2), adhesion, and invasion (ITGA6, SERPINE1). Reexpression of the most differentially repressed family member, miR-30a-5p, suppressed this mRNA program, selected signaling proteins and pathways, and inhibited cell proliferation, migration, and invasion in vitro. Furthermore, a novel miR-30a-5p mimic formulated into a targeted nanomedicine significantly inhibited HNSCC xenograft tumor growth and target growth receptors EGFR and MET in vivo. Significantly decreased miR-30a/e family expression was related to DNA promoter hypermethylation and/or copy loss in TCGA data, and clinically with decreased disease-specific survival in a validation dataset. Strikingly, decreased miR-30e-5p distinguished oropharyngeal HNSCC with poor prognosis in TCGA (P = 0.002) and validation (P = 0.007) datasets, identifying a novel candidate biomarker and target for this HNSCC subset.

Conclusions:

We identify the miR-30 family as an important regulator of signal networks and tumor suppressor in a subset of HNSCC patients, which may benefit from miRNA replacement nanomedicine therapy.
Role of Krüppel-like Factor 4-p21CIP1 Axis in Breast Cancer Stem-like Cell Inhibition by Benzyl Isothiocyanate
Authors: Kim Su-Hyeong , Singh Shivendra V.
Published: February 2019

Cancer chemoprevention by benzyl isothiocyanate (BITC), which is derived from cruciferous vegetables like garden cress, in a transgenic mouse model of breast cancer is associated with inhibition of breast cancer stem-like cells (bCSC), but the molecular regulators of this effect remain elusive. This study demonstrates a protective effect of Krüppel-like factor 4 (KLF4)-p21CIP1 axis in bCSC inhibition by BITC. Exposure of human breast cancer cells (MCF-7, MDA-MB-231, and SUM159) to plasma-achievable concentrations of BITC resulted in a robust induction of KLF4 mRNA and its protein expression as determined by qRT-PCR and Western blotting or confocal microscopy. BITC-mediated suppression of bCSC markers, including aldehyde dehydrogenase 1 activity and mammosphere frequency, was significantly augmented by transient or stable knockdown of KLF4. Western blotting and IHC revealed relatively higher levels of KLF4 protein in mammary tumor sections from BITC-treated mice in comparison with controls, but the difference was insignificant. Analysis of the breast cancer RNA-Seq data from The Cancer Genome Atlas indicated significant positive correlation between expression of KLF4 and that of p21CIP1 (CDKN1A) but not β-Catenin (CTNNB1). Knockdown of p21CIP1 protein also amplified BITC-mediated suppression of bCSC. Finally, KLF4 was recruited to the promoter of p21CIP1 as indicated by chromatin immunoprecipitation assay. These results indicate that induction of KLF4–p21CIP1 axis attenuates inhibitory effect of BITC on bCSC self-renewal. Translational implication of these findings is that breast cancer chemoprevention by BITC may be augmented with a combination regimen involving BITC and an inhibitor of KLF4.
Validity of Commonly Used Heart Rate Variability Markers of Autonomic Nervous System Function
Authors: Thomas Bianca Lee , Claassen Nicolaas , Becker Piet , Viljoen Margaretha
Published: February 2019

Background: Despite strong reservations regarding the validity of a number of heart rate variability (HRV) measures, these are still being used in recent studies. Aims: We aimed to compare the reactivity of ostensible sympathetic HRV markers (low and very low frequency [LF and VLF]) to that of electrodermal activity (EDA), an exclusively sympathetic marker, in response to cognitive and orthostatic stress, investigate the possibility of LF as a vagal-mediated marker of baroreflex modulation, and compare the ability of HRV markers of parasympathetic function (root mean square of successive differences [RMSSD] and high frequency [HF]) to quantify vagal reactivity to cognitive and orthostatic stress. Results: None of the purported sympathetic HRV markers displayed a reactivity that correlated with electrodermal reactivity. LF (ms2) reactivity correlated with the reactivity of both RMSSD and HF during baroreflex modulation. RMSSD and HF indexed the reactivity of the parasympathetic nervous system under conditions of normal breathing; however, RMSSD performed better as a marker of vagal activity when the task required breathing changes. Conclusions: Neither LF (in ms2 or normalized units [nu]) nor VLF represent cardiac sympathetic modulation of the heart. LF (ms2) may reflect vagally mediated baroreflex cardiac effects. HRV linear analysis therefore appears to be restricted to the determination of vagal influences on heart rate. With regard to HRV parasympathetic markers, this study supports the suggestion that HRV frequency domain analyses, such as HF, should not be used as an index of vagal activity in study tasks where verbal responses are required, as these responses may induce respiratory changes great enough to distort HF power.

Published: February 2019

Background: Unplanned hospital readmissions are a major source of morbidity among dialysis patients, in whom the risk of hospital readmission is exceptionally high. The contribution of dialysis facility staffing to hospital readmission has been largely overlooked. Methods: Using annual data of dialysis patients from the United States Renal Data System from 2010 to 2013, we assessed dialysis facilities with a significantly worse (SW) and facilities with a nonsignificant (NS) standardized readmission ratio (SRR). SRR estimates were risk adjusted for patient factors, past year comorbidities, and index hospitalization characteristics. Facility staffing variables were compared between 2 exposure groups: facilities with SW and NS SRRs. Four measures of staffing, including patient-to-staffing ratio, were compared between SW and matched NS facilities. Results: About 136,000–148,000 dialysis patients with 269,000–319,000 index hospital discharges were used to identify facilities with SW and facilities with NS SRR annually. Approximately 3–4% of facilities were identified as having SW SRR among > 5,000 facilities annually. The percent of nurses-to-total staff was significantly lower in 2010 for SW facilities than in matched NS facilities (42.5 vs. 45.6%, p = 0.012), but this disparity was attenuated by 2013 (44.8 vs. 44.7%, p = 0.949). There was a higher patient-to-nurse ratio for SW facilities than for NS facilities (mean 16.4 vs. 15.2, p = 0.038) in 2010 as well, and the disparity was reduced by 2013. The trends were similar for patient-to-total staff and patient-to-registered nurse, but not statistically significant. Conclusions: This study found that dialysis facilities with SW 30-day readmission rates had lower proportions of nurses-to-total staff and higher patient-to-nurse ratios, but this disparity improved in recent years. Additional research is warranted focusing on how evidence-based staffing at dialysis facilities can contribute to reduction of hospital readmission, and this knowledge is needed to inform clinical practice guidelines and policy decisions regarding optimal dialysis patient staffing.

Este artigo estuda aspectos psicossociais da cultura em importantes momentos da existência humana, como a morte e o desenvolvimento da subjetividade e individuação, enfocando os sentimentos, emoções e conflitos que cada uma dessas etapas faz emergir. Nesse contexto, aborda como mitos, ritos, símbolos e linguagens possibilitam elaborar esses processos de um ponto de vista individual e coletivo, permitindo a superação dos conflitos e ambivalências que os acompanham. Nesse processo, meios e linguagens, bem como a construção da memória, se tornam especialmente importantes. Autores como Jacques Lacan, Sigmund Freud e Roland Barthes, entre outros, dão suporte teórico às análises. O mito de Antígona, transcrito na obra de Sófocles, ajuda a desenvolver o tema.

The authorship and date of the genus-group name Pachylomera (Coleoptera: Scarabaeidae)
Authors: ZIANI STEFANO , BRANCO TRISTÃO
Published: February 2019

In 1828, the English entomologist and clergyman William Kirby described Scarabaeus femoralis using material from the collection of another English entomologist and clergyman, Frederick William Hope. The holotype of Scarabaeus femoralis Kirby, 1828 (Fig. 1) is in the Hope Entomological Collections, Oxford University Museum of Natural History (hereafter referred to as OUMNH). The genus Pachylomera was subsequently erected for this species widespread in central and southern Africa. The purpose of this note is to demonstrate, under the rules of the International Code on Zoological Nomenclature (1999), that Griffith & Pidgeon (1831) should be credited with the authorship of the genus-group name Pachylomera.
Morphological distinction of species of Thrichomys (Rodentia: Echimyidae) through ontogeny of cranial and dental characters
Authors: DA S. A. NEVES ANTONIO CARLOS , PESSÔA LEILA MARIA
Published: February 2019

Recent cytogenetic and molecular studies changed the monotypic status of the genus Thrichomys, recognizing at least four species. In this study we analyzed cranial and dental characters throughout ontogeny to investigate morphological differences between three species from Brazil: Thrichomys laurentius, from Caruaru, Pernambuco State; Thrichomys inermis, from Morro do Chapéu, Bahia state; and Thrichomys pachyurus, from Barão de Melgaço, Mato Grosso state. The samples were chosen by proximity to type localities and availability in collections. We described age classes for each species, grouped in four categories: juvenile, sub-adult, adult and senile. The unique pattern of wear of cheekteeth described in literature to the genus was made for a population from Bodocó, Pernambuco and was different of the patterns described in this study. The three patterns of tooth wear also differed from each other. In the analysis of the skull, three of the 14 characters observed did not vary during the ontogeny of each species or among the species examined. Four characters observed varied during the ontogeny of the three species examined, but in a similar way. The eight other cranial characters analyzed varied during ontogeny of the species and differently in each species. Among these eight characters, four were useful to distinction of species of Thrichomys. These characters were stable during the ontogeny of each species but were different among the three species: the shape of the interpremaxilar foramen, the shape of the incisive foramen, the shape of hamular processes, and the shape of the angle of mesopterygoid fossa. The description of the ontogenetic series of these species showed marked differences between them, corroborating morphologically the distinction of three different species.
Review of the native Hawaiian leafhopper genus Nesophrosyne (Hemiptera: Cicadellidae: Deltocephalinae) with description of eight new species associated with Broussaisia arguta (Hydrangeaceae)
Authors: BENNETT GORDON M , O’GRADY PATRICK M
Published: February 2019

A review of the native Hawaiian leafhopper genus Nesophrosyne (Hemiptera: Cicadellidae: Deltocephalinae) is presented. Specimens were examined from across the entire Hawaiian Archipelago, Nesophrosyne is redescribed, and the subgenus Nesoreias is synonymized with Nesophrosyne. Eight new species associated with the widespread host plant species Broussaisia arguta are described: N. heopoko sp. n. from Kaua’i; N. makaihe sp. n. from O’ahu; N. magnaccai sp. n. from Moloka’i; N. broussaisiai sp. n., N. ogradyi sp. n., and N. kaupoi sp. n. from Maui; and, N. aakokohaikea sp. n. and N. kanawao sp. n. from Hawai’i Island. Morphological and molecular characters were employed to delineate new species. Populations associated with B. arguta on different islands, individual volcanic mountains, and discrete geographic areas represent reciprocally monophyletic species. A monophyletic complex of five sibling species, morphologically cryptic on individual islands, were identified from Maui and Hawai’i Island. The kanawao species group is erected for these species and is further subdivided into two species subgroups based on monophyly, island endemicity, and morphology: broussaisiai species subgroup containing N. broussaisiai, N. ogradyi, and N. kaupoi on Maui; and, aakokohaikea species subgroup containing N. aakokohaikea and N. kanawao on Hawai’i Island.

Authors: HESPENHEIDE HENRY A. , WESTCOTT RICHARD L. , BELLAMY CHARLES L.
Published: February 2019

The genus Agrilus Curtis 1825 is reviewed for the Baja California peninsula of Mexico. Of the 25 species included, 11 are recorded here for the first time and four are previously unknown to science and described as new: Agrilus barri new species, A. interstitialis new species, A. vescivittatus new species, and A. argythamniae new species. Four additional species may be expected based on their occurrence just north of the border in the United States. Upon further study Agrilus auroguttatus Schaeffer 1905, revalidated status, is judged to be a separate species from A. coxalis Waterhouse 1889. Figures and a key to known and expected species are given, as well as a summary checklist.

Revalidation of the genus Thoracophelia Ehlers, 1897, replacing Euzonus Grube, 1866 (Polychaeta: Opheliidae), junior homonym of Euzonus Menge, 1854 (Arthropoda: Diplopoda), together with a literature summary and updated listing of Thoracophelia species
Authors: BLAKE JAMES A.
Published: February 2019

Brewer et al. (2011) recently demonstrated that the generic name Euzonus was being used in both Arthropoda (Diplopoda) and Polychaeta (Opheliidae) systematics and that the arthropod name was the senior synonym. The diplopod name Euzonus Menge, 1854, based on a single species, E. collulum Menge, 1854 from Baltic amber predates Euzonus Grube, 1866, established for E. arcticus Grube, 1866 from the Arctic Ocean. The Nomenclator Zoologicus (2005) verifies that both names are listed as uncorrected homonyms.
Panava a senior synonym of Wulpisca, and description of new species of Panava and Dexosarcophaga (Bezzisca) from the Brazilian Amazon (Diptera, Sarcophagidae)
Authors: DA SILVA CARVALHO FILHO FERNANDO , ESPOSITO MARIA CRISTINA
Published: February 2019

The generic name Wulpisca Lopes is placed as a junior synonym of a redefined Panava Dodge, a Neotropical taxon characterized by short apical spines on the male surstylus, a single phallotreme, presence of proclinate frontorbital bristles in the male, and setose wing vein R 1 . The species W. imbecilla (Wulp) and W. arnaudi Lopes are transferred to Panava and a new species, P. amazonica sp. nov., is described from Brazil. A key to males of the seven species of Panava is given. The subgenus Bezzisca Lopes of the predominantly Neotropical genus Dexosarcophaga Townsend comprises 17 species, including a new one described herein, D. (B.) tracua sp. nov. from Brazil. The key to species of D. (Bezzisca) by Silva and Mello-Patius (2010) is modified to include this new species.
New species of small, bathypelagic calanoid copepods from the Arctic Ocean: Brodskius arcticus sp. nov. (Tharybidae) and three new species of Pertsovius gen. nov. (Discoidae)
Authors: ANDRONOV VLADIMIR N. , KOSOBOKOVA KSENIA N.
Published: February 2019

A new calanoid copepod species, Brodskius arcticus sp. nov. (family Tharybidae Sars, 1902), and three new species of a new genus Pertsovius gen. nov. (family Discoidae Gordejeva, 1975) are described from deep waters of the Arctic Canada Basin. The female of Brodskius arcticus differs from five of the other six known species of this genus in the absence of rostral filaments, the lack of which it shares with B. abyssalis Markhaseva & Schulz, 2007. This new species differs from B. abyssalis in having two very short outer proximal spines at the distal segment of the fifth swimming legs (P5). The length of these spines is less than half the width of the segment, whereas in B. abyssalis they are longer than the width of the segment. The new genus Pertsovius is created here for a group of seven species within the family Discoidae which have one-segmented endopods of Р 2-Р4. In contrast, the other genera of this family have three-segmented endopods of Р 2-Р4. The three new species of Pertsovius differ from each other in the appearance of the genital field, and in the number of outer border spines on the distal exopodal segment of P2. In Pertsovius tridentatus sp. nov. this segment bears three external spines on both left and right P2. The left Р 2 of P. heterodentatus sp. nov. has three spines, while the right Р 2 bears two spines only. The distal segments of both left and right Р 2 of P. serratus sp. nov. have two external spines, but the proximal part of the external margin on the left Р 2 bears three relatively large denticles. The distal exopodal segments of Р 2 of the other four species here transferred to the genus Pertsovius are smooth with no external spines or denticles, but each bears two outer border spines.
