Adversarial Attacks in IoT: A Performance Assessment of ML and DL Models
No full textThe rise of IoT devices has led to significant advancements but also new security challenges. This paper assesses the performance of various machine learning (ML) models—Decision Trees, Naïve Bayes, Support Vector Machines (SVMs), and a deep learning model (CNN)—against adversarial attacks using the IoT-23 dataset. Attacks tested include the Fast Gradient Sign Method (FGSM) and Projected Gradient Descent (PGD). Findings show that Decision Trees are the most robust, while CNNs are the most vulnerable, highlighting the need for improved defenses in IoT systems and suggesting new research avenues in adversarial learning

Synergistic antibacterial activity of chitosan-polyethylene glycol nanocomposites films containing ZIF-8 and doxycycline
No full textAbstract Background Antibiotic resistance is a growing global threat due to antibiotic overuse and limited treatment options. Multidrug-resistant bacteria, like Staphylococcus aureus and Escherichia coli, increase infection complexity and mortality. This study explores nanocomposite films of ZIF-8 nanoparticles and Doxycycline (Dox) to enhance antibacterial efficacy. In this study, nanocomposite films composed of chitosan (CS) and polyethylene glycol (PEG), incorporating zeolitic imidazolate framework-8 (ZIF-8) nanoparticles and DOX, were developed. These films were characterized by their morphological, mechanical, antibacterial, and drug-release properties. Antibacterial efficacy was evaluated using disk diffusion, broth microdilution, and checkerboard assay methods to determine MICs and potential synergistic effects. Results The nanocomposite films demonstrated flexibility, semi-transparency, and a yellowish-brown hue, with films containing ZIF-8 nanoparticles being thicker (79 ± 0.2 μm) than those without (54 ± 0.5 μm). The tensile strength was enhanced with the incorporation of ZIF-8, peaking at 53.12 MPa for the CS-PEG-G-10% DOX-4% ZIF-8 film. XRD analysis confirmed the crystallinity of the ZIF-8 and DOX, with distinct peaks observed for each material. The drug release studies revealed an initial burst followed by sustained release, with higher release rates in acidic environments compared to neutral and alkaline media. The CS-PEG-G-10% DOX-4% ZIF-8 nanocomposite film demonstrated significantly higher antibacterial activity, achieving the lowest MIC values, particularly against S. aureus (22.5 mm inhibition zone) compared to E. coli (14 mm inhibition zone). Additionally, a notable synergistic effect was observed between CS-PEG-G-10% DOX and CS-PEG-G-10% DOX, with FICI values below 0.5. Conclusions The CS-PEG-G-10% DOX-4% ZIF-8 nanocomposite exhibits enhanced antibacterial efficacy and optimal properties, positioning it as a strong candidate for developing effective treatments against multidrug-resistant pathogens

Comparative incidence of enterobius vermicularis using cellulose tape method among children 4-8 years old between a rural and urban community in Dasmarinas, Cavite, 2013-2014
No full textThe study used an analytical cohort type of study. One hundred twenty three (123) children 4-8 years old from Barangays H-2 (rural community) and 123 children 4-8 years old from Langkaan II (urban community) were selected using stratified cluster probability sampling method. Data was collected using the tape test method. The communities were randomly selected. The rural community had a greater incidence of Enterobis vermicularis infections than urban community with 31.71% and 5.60% respectively. The use of private drinking water source was a preventive factor (p value=0.04)

MYANMAR: 1♂, 6 specimens (NHMW): Mandalay, ca. 50 km NW Kalaw,Myitsona river, 450 m, 25.x.1998,lgt.Schillhammer. Redescription. Body length 1.5–2.0 mm (holotype 1.9 mm), maximum body width 1.0– 1.1 mm (holotype 1.0 mm). Head and labrum black; pronotum yellowish with vaguely delimited darker central spot of variable extent or in some specimens (incl. holotype) completely dark brown; elytra yellowish with darkened elytral striae, or with darker lateral parts, or uniformly brown (incl. in holotype); legs yellowish to brown. Head with weak microsculpture on interstices; punctation sparse, each puncture bearing pointed seta. Eyes separated by 3.1× the width of one eye in dorsal view. Pronotum with sparse setiferous punctation similar to that on head; interstices without microsculpture. Elytra with 10 striae sharply impressed except anteromedially (near scutellar shield) where neither striae nor serial punctures are visible (but darker spots may be present, resembling real punctures); intervals weakly convex at midlength and near apex; interval punctation sparse, setiferous; interstices without microsculpture. Aedeagus (Figs 7 A–J) c. 0.5 mm long. Phallobase not much wider at base of parameres than more basally, only indistinctly narrowed at midlength; arcuate in lateral view. Paremere wide basally, gradually narrowing towards apex, outer face nearly continuously arcuate, slightly bisinuate in apical fourth, apex bluntly pointed; mesal face with short cuticular asperities (visible in cleaned aedeagus only, Fig. 7E). Median lobe widely bottle-shaped, without paired subapical projections; apex nearly reaching level of parameral apices, membranous, rounded in relaxed position (Figs 7D, I–J), with a pair of backwards directed lobes when fully everted (not usually visible); gonopore rounded, situated subapically. Differential diagnosis. Thysanarthria championi resembles T. bifida sp. nov., T. trifida sp. nov., and T. chui sp. nov. in the general morphology of the aedeagus and the basally wide parameres arcuately narrowing into widely to narrowly rounded apex; of these T. bifida and T. trifida can be distinguished by the presence of a pair of subapical projections on the median lobe (absent in T. championi); T. chui lacks these lobes, but its parameres are relatively shorter and more abruptly narrowed apically, projecting into rounded lobes. Thysanarthria championi is one of four species co-occurring in Himalaya, along with T. madurensis, T. saurahana sp. nov., and T. siamensis; it can be easily distinguished from all of them by the morphology of male genitalia. Comments on synonymy. The above type specimen of Chaetarthriomorphus sulcatus is the only found in the Klapperich collection in HNHM. It is largely damaged, with prothorax and one elytron completely missing. However, the abdomen and male genitalia are present, and the morphology of the aedeagus corresponds completely with that of the lectotype of T. championi. The elytron is paler, not dark brown, which further supports the fact that C. sulcatus cannot be conspecific with the specimens from southern Iran (described here as T. persica sp. nov.) and the northern Arabian Peninsula (described here as T. wadicola sp. nov.) as erroneously reported by HEBAUER (1997) and FIKÁČEK et al. (2010). Following these facts, the examined specimen is designated as the lectotype, and Chaetarthriomorphus sulcatus is here placed in synonymy with Chaetarthria championi. Biology. Part of the examined specimens was collected at light on river banks, no more information is available. Distribution. The species is widely distributed in the foothills of the Himalaya Mts. and the adjacent mountain systems in eastern Afghanistan (Hindukush Mts.), southwestern China (Yunnan), and Myanmar. The specimens listed by HEBAUER (2001) from Laos are females and hence their identity cannot be confirmed.Published as part of Fikáček, Martin & Liu, Hsing-Che, 2019, A review of Thysanarthria with description of seven new species and comments on its relationship to Chaetarthria (Hydrophilidae: Chaetarthriini), pp. 229-252 in Acta Entomologica Musei Nationalis Pragae 59 (1) on pages 242-243, DOI: 10.2478/aemnp-2019-0020, http://zenodo.org/record/448891
