Lattice-based Public Key Encryption with Authorized Keyword Search: Construction, Implementation, and Applications

Public key encryption with keyword search (PEKS), formalized by Boneh et al. [EUROCRYPT’ 04], enables secure searching for specific keywords in the ciphertext. Never-theless, in certain scenarios, varying user tiers are granted disparate data searching privileges, and administrators need to restrict the searchability of ciphertexts to select users exclusively. To address this concern, Jiang et al. [ACISP’ 16] devised a variant of PEKS, namely public key encryption with authorized keyword search (PEAKS), wherein solely authorized users possess the ability to conduct targeted keyword searches. Nonetheless, it is vulnerable to re-sist quantum computing attacks. As a result, research focusing on authorizing users to search for keywords while achieving quantum security is far-reaching. In this work, we present a novel construction, namely lattice-based PEAKS (L-PEAKS), which is the first mechanism to permit the authority to authorize users to search different keyword sets while ensuring quantum-safe properties. Specifically, the keyword is encrypted with a public key, and each authorized user needs to obtain a search privilege from an authority. The authority distributes an authorized token to a user within a time period and the user will generate a trapdoor for any authorized keywords. Technically, we utilize several lattice sampling and basis extension algorithms to fight against attacks from quantum adversaries. Moreover, we leverage identity-based encryption (IBE) to alleviate the bottleneck of public key management. Furthermore, we conduct parameter analysis, rigorous security reduction, and theoretical complexity comparison of our scheme and perform comprehensive evaluations at a commodity machine for completeness. Our L-PEAKS satisfies IND-sID-CKA and T-EUF security and is efficient in terms of space and computation complexity compared to other existing primitives. Finally, we provide two potential applications to show its versatility.
Person Reidentiﬁcation by Minimum Classiﬁcation Error-Based KISS Metric Learning

—In recent years, person reidentiﬁcation has received growing attention with the increasing popularity of intelligent video surveillance. This is because person reidentiﬁcation is critical for human tracking with multiple cameras. Recently, keep it simple and straightforward (KISS) metric learning has been regarded as a top level algorithm for person reidentiﬁcation. The covariance matrices of KISS are estimated by maximum likelihood (ML) estimation. It is known that discriminative learning based on the minimum classiﬁcation error (MCE) is more reliable than classical ML estimation with the increasing of the number of training samples. When considering a small sample size problem, direct MCE KISS does not work well, because of the estimate error of small eigenvalues. Therefore, we further introduce the smoothing technique to improve the estimates of the small eigenvalues of a covariance matrix. Our new scheme is termed the minimum classiﬁcation error-KISS (MCE-KISS). We conduct thorough validation experiments on the VIPeR and ETHZ datasets, which demonstrate the robustness and effectiveness of MCE-KISS for person reidentiﬁcation.
Eco-Efficiency and Financial Performance: An Eco-Efficiency and Financial Performance: An Evidence from Indonesian Listed Company Evidence from Indonesian Listed Company

This study uses natural resource-based theory to provide empirical evidence regarding the effect of sustainability policies in the form of emission reductions on the financial performance of companies listed on the Indonesia Stock Exchange. The concept of eco-efficiency is measured using the emission intensity approach. This study uses a period of data panels from 2019 to 2021 to capture the effect of eco-efficiency on the company’s financial performance. Using three accounting measures of financial performance in the research model: ROA, ROE, and ROS, to understand in more detail the impact of eco-efficiency on the company’s financial performance. We find evidence that eco-efficiency has a positive impact on financial performance. This finding implies that the fewer GHG emissions the company produce, the higher the company’s financial performance. This finding has implications as support for companies that emission reduction policies can positively affect the company’s financial performance.
Sustainable futures for Europe’s HERitage in CULtural landscapES: Tools for understanding, managing, and protecting landscape functions and values

We compare and contrast rural land manager current about agri-environmental schemes (AES) and preferences for design beyond 2020 across different understandings of landscape stewardship. Forty semi-structured interviews were conducted with similar proportions of smallholders, medium holders and large holders in South West Devon, United Kingdom. Overall, respondents most frequently cited concerns related to the reduced amount of funding available for entry-level and higher-level stewardship schemes in the UK since 2008, changing funding priorities, perceived overstrict compliance and lack of support for farm succession and new entrants into farming. However, there were differences in concerns across understandings of landscape stewardship with production respondents citing that AES do not encourage food production, whereas environmental and holistic farmers citing that AES do not support the development of a local green food culture and associated social infrastructure. These differences also emerged in preferences for AES design beyond 2020. In the light of these findings, we adapt a collaborative and co-ordinated framework for designing AES to account for the differing interests of land managers based on their understanding of landscape stewardship. We discuss the implications of this framework for environmental policy design in the Europe Union and elsewhere.
East African Journal of Health and Science

The advent of Anti-Retroviral Therapy (ART) has resulted in remarkable improvement in the management of Human Immuno-deficiency Virus (HIV) and Acquired Immune Deficiency Syndrome (AIDS). Adherence to ART and other HIV and AIDS treatment modalities amongst HIV seropositive mothers has resulted in a reduction in the rate of Mother-To-Child Transmission (MTCT) of HIV. Nonetheless, MTCT of HIV rates remain high in Homa Bay County, Kenya, with 8.8% MTCT of HIV. This rate is higher than the World Health Organization (WHO) target of reducing MTCT of HIV to less than 5%. The study assessed maternal determinants of Prevention of Mother-to-Child Transmission (PMTCT) of
Bioavailability and diagenetic state of dissolved organic matter in riparian groundwater

[1] Riparian groundwater can exhibit considerable patchiness in the concentration and reactivity of dissolved organic matter (DOM), which ultimately shapes subsurface biogeochemical transformations. Free and combined amino acids are bioavailable constituents of DOM, and their concentration and composition can provide valuable information about the diagenetic state of DOM. Based on riparian groundwater samples and relevant DOM end-member samples, we adapted the amino-acid-based marine DOM degradation index (DI) to groundwater. The groundwater DI was applied to evaluate the spatial and temporal variability in the bioavailability and diagenetic state of riparian DOM in a restored and a channelized section of the River Thur, Switzerland. Among different indicators for DOM diagenetic state (total hydrolysable amino acid concentrations, C-normalized yields, and the contribution of nonprotein amino acids), the groundwater DI correlated best with the activity of the enzyme leucine-aminopeptidase and bacterial secondary production in riparian groundwater. The “freshest” DOM was consistently found in the channel and during high-flow conditions in the groundwater of the restored riparian section and was spatially constrained to a zone inhabited by a dense willow population. The use of amino acid data and the newly developed DI for DOM in groundwater is a promising approach for characterizing the spatial and temporal dynamics of DOM reactivity and diagenesis within riparian groundwater.
One century of land use changes in the metropolitan area of Milan (Italy)

Abstract This paper presents the possible contribution of multi-temporal Landsat Thematic Mapper (TM) data to the assessment of land-use modifications in the most important portion of the metropolitan area of Milan where rapid transformations, starting from urban areas and then gradually extending to rural areas, took place. The study area corresponds to the so-called ‘Great Milan’ which includes a protected area, the ‘South Milan Agricultural Park’, where a widespread conflict between agricultural and-urban land use has arisen. Park realisation will contribute improving agricultural activities and creating a belt for environment protection around the city. Digital thematic maps, digitizing Istituto Geografico Militare dTtalia cartography of 1888–90 and 1945–50, were extracted. Normalized Difference Vegetation Indices (NDVI) were produced from three Landsat-5 Thematic Mapper images of 1984, January, June and August, and a Multi-temporal Colour NDVI Composition (MCNC) output was produced.

Potential Distribution of Frankliniella occidentalis (Pergande) (Thysanoptera: Thripidae) in China by Using Combined CLIMEX and GIS Tools

【Objective】Frankliniella occidentalis (Pergande) is an important pest worldwide and its occurrence in China was firstly reported in Beijing in 2003. So it is urgent to predict its potential suitable distribution area in China. 【Method】The EI value of F. occidentalis output from CLIMEX model was interpolated into the GIS analysis. After overlay analysis of some biotic and non-biotic factors, the prediction of the potential distribution of F. occidentalis in China was improved significantly comparing with the prediction by CLIMEX alone. 【Result】The results showed that F. occidentalis can widely distribute in south areas of the Yellow River, the Weihe River and it may cause serious damages in Yunnan and Guizhou Plateau, the Weihe vally, the Huaihe valley, Guangdong, Guangxi, and Zhejiang provinces, etc. 【Conclusion】F. occidentalis can occur in Center China, Southern China and Southwestern China. It can also happen seriously in Northern China if weather conditions are suitable and overwintering places exist.
A model study of density intrusions into and circulation within a deep, silled estuary: Puget Sound

A laterally averaged hydrodynamical model is used to investigate episodic intrusions of denser, more oceanic water across the shallow double-silled entrance of Puget Sound and the resulting circulation within the interior deep basin. Tidal, freshwater discharge and wind effects are also encompassed in model results. Model simulations were made of the 4-month period from December 1983 through March 1984. During that period, hourly measurements of currents and salinity were made at the estuary entrance and on four moorings in the interior basin. The first 60 days of salinity data were used with the model to choose rates of vertical turbulent mixing and the lag times between fresh water appearance at river gauges and its arrival in the main basin of the sound. Comparison of model results with the full 120 days of salinity and velocity data shows that the model incorporates the important circulation features of this estuary. The model was then used to study intrusions and mixing in the sill region. The model identifies these factors as controls on the occurrence and strength of intrusions: the trans-sill salinity gradient, the intensity of tidal stirring and mixing over the sills, the supply of fresher surface water resulting from river runoff, and the winds. Time series of salinities in the interior basin show local maxima following local maxima in the trans-sill salinity difference. Vertical transport in the sill region at both tidal and subtidal time scales is dominated by advection rather than diffusion. Though much of the vertical exchange occurs over the shallower sill, a depth depression between the two entrance sills appears to be the site of significant overturning. Downwelling of surface water occurs on the landward side of both sills. Substantial freshening of the interior basin occurs during the winter months because river discharges are large and are stirred downward in the sill region to be entrained into landward bottom flows. Extraordinarily large river discharges can suppress the effect of large trans-sill salinity differences with the effect of weakening potential intrusions. Winds can indirectly influence intrusions by longitudinally positioning fresher, river-influenced surface water in the sill region. Winds can directly influence intrusions via bottom compensation flows in Admiralty Inlet, with northward winds encouraging intrusions, and by changing salinities at the entrance to the sound, and thus the trans-sill salinity gradient.
Importance of optimizing duration of adjuvant immune checkpoint inhibitor therapy to treat postoperative hepatocellular carcinoma after conversion therapy: a case report

Abstract Patients with hepatocellular carcinoma at high risk of recurrence after hepatic resection or local ablation often undergo adjuvant immunotherapy with immune checkpoint inhibitors for 1 year in randomized controlled trials, but the appropriateness of this duration is controversial, especially given the risk of adverse events. Here we report the case of a 52-year-old Chinese man with initially unresectable multinodular recurrent hepatocellular carcinoma who underwent two cycles of transarterial chemoembolization, followed by hepatic resection and 24 months of adjuvant therapy with the PD-1 inhibitor tislelizumab. The patient achieved a recurrence-free survival time of 24 months, but he experienced elevated alpha fetoprotein, Grade 2 hypothyroidism and pruritus while on adjuvant therapy. This case highlights the need to optimize the duration of adjuvant immunotherapy after curative treatment for hepatocellular carcinoma in order to minimize risk of not only recurrence but also adverse events.
Small bowel obstruction caused by a mango phytobezoar within a Meckel’s diverticulum

Abstract A fit and well gentleman in his 40s presented with vomiting and obstipation. His only relevant history being recent ingestion of a large quantity of mangoes. A computer tomography demonstrated a small bowel obstruction with a transition point in the right iliac fossa, but no other pathological findings. After a short period of non-operative management he proceeded to surgery, where a phytobezoar was identified at a Meckel’s diverticulum causing a pantaloon shaped intra-luminal obstruction. A small bowel resection and primary anastomosis was performed and the patient had an uncomplicated post-operative course. Meckel’s diverticuli are a relatively common phenomenon and may pre-dispose to bowel obstructions through a number of different mechanisms. This unusual case highlights the importance of considering this as a differential, and one that will likely require timely operative intervention.
Molecular Identification and Antioxidant Activity Determination among Coffee Varieties Cultivated in Nepal

Coffee is the most popular beverage containing numerous phytochemical components that have antioxidant activity capable of scavenging free radicals. Antioxidant and phenolic contents have considerable benefits for human health. The aim of this study was the molecular identification of 9 coffee samples from the Nepal Agricultural Research Council, Lalitpur, Nepal, and the determination of the antioxidant activity and total phenolic content of green and roasted coffee beans. Molecular identification was performed using ITS-specific PCR followed by sequencing and phylogenetic tree construction using the maximum parsimony method. The DPPH assay was used to determine the antioxidant activity, and the Folin–Ciocalteu (F-C) assay was used to determine the total phenolic content. All the samples belonged to the taxa Coffea arabica. The antioxidant activity in roasted beans varied from 2.49 to 4.62 AAE mg/g and from 1.4 to 3.9 AAE mg/g in green beans. The total phenolic content varied from 2.58 to 3.38 GAE mg/g and from 4.16 to 5.36 GAE mg/g for the roasted beans and green beans, respectively. The data revealed that the highest antioxidant content (4.62 AAE mg/g) was found in roasted coffee and that the highest phenolic content (5.36 GAE mg/g) was found in green coffee. The study concludes that roasting increases the antioxidant activity but decreases the phenolic content of coffee.
Extensive suprasternal dehiscence reconstruction with NPWT and advancement flaps following cardiac surgery

Abstract Treatment of suprasternal wound infection (SSWI) following cardiac surgery is not a clearly developed procedure. We report our female patient’s secondary SSWI treatment following bypass surgery. An obese female patient with unstable angina underwent an urgent, uneventful off-pump coronary artery bypass operation. An SSWI appeared within a week. After negative pressure wound therapy (NPWT), the sternum was rewired. In the previously irradiated territory of the left breast necrosis formed, a plastic surgeon reconstructed a defect. This procedure failed NPWT was restarted again, and a secondary reconstructive plastic surgery intervention was necessary. Despite extensive tissue mobilization, the central part of the reconstructive area necrotized, and we had to cover it with a split thickness skin mash graft. The irradiation therapy increases the incidence of suprasternal and/or sternal infection. It was possible to manage large soft tissue defects with bilateral and rotational advancement flaps.
Antibacterial and antibiofilm activity of Abroma augusta stabilized silver (Ag) nanoparticles against drug-resistant clinical pathogens

Infectious diseases remain among the most pressing concerns for human health. This issue has grown even more complex with the emergence of multidrug-resistant (MDR) bacteria. To address bacterial infections, nanoparticles have emerged as a promising avenue, offering the potential to target bacteria at multiple levels and effectively eliminate them. In this study, silver nanoparticles (AA-AgNPs) were synthesized using the leaf extract of a medicinal plant, Abroma augusta. The synthesis method is straightforward, safe, cost-effective, and environment friendly, utilizing the leaf extract of this Ayurvedic herb. The UV-vis absorbance peak at 424 nm indicated the formation of AA-AgNPs, with the involvement of numerous functional groups in the synthesis and stabilization of the particles. AA-AgNPs exhibited robust antibacterial and antibiofilm activities against methicillin-resistant Staphylococcus aureus (MRSA) and vancomycin-resistant Enterococci (VRE). The MIC values of AA-AgNPs ranged from 8 to 32 μg/mL. Electron microscopic examination of the interaction of AA-AgNPs with the test bacterial pathogens showed a deleterious impact on bacterial morphology, resulting from membrane rupture and leakage of intracellular components. AA-AgNPs also demonstrated a dose-dependent effect in curtailing biofilm formation below inhibitory doses. Overall, this study highlights the potential of AA-AgNPs in the successful inhibition of both the growth and biofilms of MRSA and VRE bacteria. Following studies on toxicity and dose optimization, such AgNPs could be developed into effective medical remedies against infections.
Steroid receptor coactivator‐2 drives epithelial reprogramming that enables murine embryo implantation

Although we have shown that steroid receptor coactivator‐2 (SRC‐2), a member of the p160/SRC family of transcriptional coregulators, is essential for decidualization of both human and murine endometrial stromal cells, SRC‐2's role in the earlier stages of the implantation process have not been adequately addressed. Using a conditional SRC‐2 knockout mouse (SRC‐2d/d) in timed natural pregnancy studies, we show that endometrial SRC‐2 is required for embryo attachment and adherence to the luminal epithelium. Implantation failure is associated with the persistent expression of Mucin 1 and E‐cadherin on the apical surface and basolateral adherens junctions of the SRC‐2d/d luminal epithelium, respectively. These findings indicate that the SRC‐2d/d luminal epithelium fails to exhibit a plasma membrane transformation (PMT) state known to be required for the development of uterine receptivity. Transcriptomics demonstrated that the expression of genes involved in steroid hormone control of uterine receptivity were significantly disrupted in the SRC‐2d/d endometrium as well as genes that control epithelial tight junctional biology and the emergence of the epithelial mesenchymal transition state, with the latter sharing similar biological properties with PMT. Collectively, these findings uncover a new role for endometrial SRC‐2 in the induction of the luminal epithelial PMT state, which is a prerequisite for the development of uterine receptivity and early pregnancy establishment.
