Alpha-DBL: A Reasonable High Secure Double-Block-Length Hash Function
Authors: Linh Hoang Dinh , Thai Tran Hong 
Published: November 2021

Abstract—We propose a new double-block-length compression function which is called Alpha-DBL. This scheme uses two parallel secure single block length schemes based on a block cipher with -bit key and -bit block size to compress a -bit string to a -bit one. We show that the Alpha-DBL scheme attains nearly optimal collision security and preimage security bounds (up to and queries for finding a collision and a preimage, respectively). More precisely, for , no adversary making less than queries can find a collision with probability greater than 1/2. To our knowledge, this collision security bound is nearly better than other such compression functions. In addition, we provide a preimage security analysis of Alpha-DBL that shows security bound of queries for . Using this scheme in the iterated hash function construction can preserve the collision resistance security and the preimage resistance security.Tóm tắt—Chúng tôi đề xuất một hàm nén độ dài khối kép mới được gọi là Alpha-DBL. Lược đồ này sử dụng hai lược đồ độ dài khối đơn an toàn song song dựa trên mã khối với khóa -bit và kích thước khối -bit để nén chuỗi -bit thành chuỗi -bit. Chúng tôi đã chứng minh rằng, lược đồ Alpha-DBL đạt được cận an toàn kháng va chạm và kháng tiền ảnh gần như tối ưu (tối đa và truy vấn tương ứng để tìm va chạm và tiền ảnh). Cụ thể với , một kẻ tấn công bất kỳ thực hiện ít hơn truy vấn chỉ có thể tìm thấy một va chạm với xác suất nhỏ hơn 1/2. Theo hiểu biết của chúng tôi, cận an toàn kháng va chạm này tốt hơn so với các hàm nén khác. Ngoài ra, chúng tôi đã đưa ra phân tích độ an toàn kháng tiền ảnh của Alpha-DBL cho thấy cận an toàn là 2 truy vấn cho . Sử dụng lược đồ này trong việc xây dựng hàm băm được lặp có thể bảo toàn độ an toàn kháng va chạm và an toàn kháng tiền ảnh.

Abstract—In this paper, we present the dynamic cryptographic algorithms for long states named ACDEL-2D and ACDEL-3D. The first one was inspired by Rijndael and the second one was inspired by 3D, a three-dimensional block cipher. In both proposals, MDS matrices are used alternately on rows and columns of the state and all transformations used in the encryption process are randomly selected depending on pseudorandom sequences. In the block cipher ACDEL-3D the state takes the form of a rectangular parallelepiped or cuboid.Tóm tắt—Trong bài báo này, chúng tôi trình bày các thuật toán mật mã động cho các trạng thái dài, có tên là ACDEL-2D và ACDEL-3D.

Authors: Dvirna Tetiana , Futorna Oksana , Minarchenko Valentyna , Tymchenko Iryna 
Published: November 2021

Abstract
The genus
Crataegus
L. is one of the largest species in the family Rosaceae Juss. The fruits are used as medicinal raw materials (
Crataegus fructus
), as they contain a set of biologically active compounds. The genus is voluminous and taxonomically problematic due to significant variability, hybridization, apomixis, and polyploidy. As a result, it is difficult to determine the species of the genus. Species of the genus have a number of diagnostic features, one of which is a distinct fruit with seeds. The aim of our study was to identify and compare the diagnostic features of the fruits of seven species of the genus
Crataegus
flora of Ukraine, which are most often used as medicinal raw materials and are the most common in Ukraine –
Crataegus laevigata
,
C. monogyna
,
C. pentagyna
,
C. pseudokyrtostyla
,
C. sanguinea
,
C. fallacina
, and
C. rhipidophylla
. The study was performed using scanning and digital microscopy, and descriptions were made by standard methods. As a result, we identified features that clearly distinguished the studied species from each other. We identified mature fruits that contain only one pyrene (
C. monogyna
,
C. pseudokyrtostyla
,
C. fallacina
, and
C. rhipidophylla
), and several pyrenes (
C. laevigata
,
C. pentagyna
, and
C. sanguinea
) among the studied species of the genus. The studied species are characterized by spherical and ellipsoidal fruits. The predominant color is fulvous/brown with different shades, but almost-black fruits of the species
C. pentagyna
are well distinguished. Fruits of all studied species of the genus are fleshy, except
C. sanguinea
, which is floury. The species is characterized mainly by yellow flesh fruits, except
C. pentagyna
, which has ribbed fruits. The fruits of
C. monogyna
plants differ from those of other studied species by the spinous-tuberous surface relief. Pyrenes of triangular shape are observed only in
C. pentagyna
. We suggest that these features can be used as additional diagnostic tools to determine the species of the genus
Crataegus
flora in Ukraine.

Published: November 2021

Background
Cordyceps militaris is a fungus that parasitizes insects. Compounds from C. militaris are valuable in medicine and functional food. There are many kinds of bacteria in the natural sclerotia of C. militaris. However, the community structure of microorganisms in samples from different places may be different, and their corresponding ecological functions require experimental verification.

Methods
We used high-throughput sequencing technology to analyze bacterial 16S rRNA gene sequences in sclerotia of three samples of C. militaris from Liaoning Province, China. We isolated, identified and verified the function of culturable bacterial strains from the sclerotia.

Results
Pseudomonas, Pedobacter, Sphingobacterium, and Serratia were the dominant bacterial genera in the sclerotia. And function prediction showed that Pseudomonas and Pedobacter could be heterotrophic, Sphingobacterium could decompose urea, and Serratia could reduce nitrate. Two strains of bacteria isolated from the sclerotia of C. militaris, N-2 and N-26, were identified as Stenotrophomonas maltophilia and Pseudomonas baetica, respectively, based on culture and biochemical characteristics. When these isolated strains were co-cultured with C. militaris, the mycelium biomass and mycelium pellet diameter decreased, and the content of extracellular polysaccharide increased. Strain N-26 decreased the cordycepin content in C. militaris.

Conclusions
Bacteria in sclerotia have an important effect on the growth of C. militaris and the production of its metabolites.

ImportanceSporadic Creutzfeldt-Jakob disease (sCJD) is a rare, rapidly progressive and fatal neurodegenerative disease. Definite sCJD diagnosis can only be made post mortem, and little is known about the prodromal phase of the disease.ObjectiveTo compare drug prescription patterns before the clinical onset of sCJD between patients and matched controls for exploration of potential risk factors and to assess correlations between drug exposure and sCJD survival.Design, Setting, and ParticipantsThis retrospective analysis was designed as a case-control study, with data collected from January 2013 to December 2020 and analyzed in 2023. Follow-up was available until December 2020. Cases were collected from the Austrian Reference Centre for Human Prion Diseases, which receives all suspected cases at a national level in Austria. The analyses were conducted at a single center. Patients with autopsy-confirmed sCJD were linked with insurance claims data, and a minimum of 10 control individuals were matched by sex, age at onset, and area of residence for each patient with sCJD.ExposureMedication prescribed to 10% or more of the cohort with sCJD up to 5 years before symptom onset or the matching date in the control cohort.Main Outcomes and MeasuresDrug prescription before symptom onset or the matching date was compared between patients with sCJD and controls using conditional regression, and prescriptions in the cohort with sCJD were assessed for correlation with survival using Cox proportional hazard models.ResultsA total of 129 patients with sCJD (median [IQR] age, 68.9 [62.4-75.5] years; 67 female [51.9%]) and 1350 controls (median [IQR] age, 69.0 [62.2-75.3] years; 700 female [51.9%]) were included. As compared with controls, patients with sCJD were found to have significantly higher odds of being prescribed selective serotonin reuptake inhibitors (SSRIs) in the year preceding disease onset (odds ratio, 2.86; 95% CI, 1.63-4.95; P &amp;lt; .001). SSRI prescription rates started to increase 3 years before symptom onset in the cohort with sCJD.Conclusions and RelevanceResults of this case-control study provide evidence for prodromal mood alterations as early as 3 years before symptom onset in patients with sCJD. Although sCJD remains an extremely rare cause of mood alterations, increased vigilance for neurodegenerative diseases in this setting could eventually help to extend the diagnostic window.

Published: December 2024

AbstractAutosomal‐dominant variants in the CPT1C gene have been associated with hereditary spastic paraplegia type 73 (SPG73), which typically presents with slowly progressive lower limb weakness and spasticity and is therefore considered a pure form of hereditary spastic paraplegia. However, we report two unrelated males with novel CPT1C variants (NM_001199753.2: patient 1: c.2057_2061del (p.Ile686SerfsTer8) and patient 2: c.2020‐1G>C (p.?)) who presented with lower limb spasticity at 4 and 3 years old, respectively. Both patients also experienced significant cognitive impairment, seizures, or neurobehavioral symptoms. These cases illustrate a broader and more complex clinical spectrum of SPG73, extending beyond the traditionally recognized pure motor symptoms.

Published: December 2024

AbstractCamouflage clothing and cloaks are widely used in the military field. However, the widespread use of unmanned aerial vehicles (UAV) equipped with infrared thermal imaging devices has rendered traditional camouflage ineffective in the face of its unparalleled detection capabilities in modern warfare. Inspired by the enhancement principles of cellulose and lignin in natural wood, the interfacial engineering of biomineralization, and the scale structure of pangolins, herein, a regenerated cellulose/lignin composite aerogel with a toast‐like structure by integrating all three biomimetic techniques into a single biomimetic design is developed. The unique toast‐like structure allows effective protection of the internal porous structure during surface modification. The prepared composite aerogel not only exhibits excellent mechanical properties but also demonstrates a desert sand‐like color, superior thermal insulation, and effective infrared blocking capabilities, highlighting its potential in thermal camouflage applications. This work proposes a green method for preparing regenerated cellulose composite aerogel sheets, which is expected to provide a design concept for the preparation, functionalization, and application of regenerated cellulose aerogel materials. In addition, factors such as the generalizability of the study, environmental impacts, and economic benefits are discussed.

AbstractThe fabrication of polymers of intrinsic microporosity (PIMs)‐based mixed matrix membranes (MMMs) is an effective strategy to combine the superior selectivity of porous nanofillers and the high gas permeability of PIMs, which is expected to be a new generation of membrane for efficient CO2 capture. However, the aggregation and sedimentation of the nanofillers along with their insufficient interfacial compatibility with PIMs matrix often result in uncontrollable defects and non‐selective voids among the polymer matrix, which seriously deteriorate the anticipated gas separation performance. For the first time, this work proposes a “solvent‐evaporation‐induced‐confinement” strategy for in situ growth of zeolitic imidazole framework‐90 (ZIF‐90) nanofillers throughout amidoxime‐functionalized PIM‐1 (AOPIM‐1) matrix. The defect‐free microporous membrane exhibits a uniform distribution of highly loaded nanofillers with excellent PIMs‐MOF interfacial compatibility. The optimized AOPIM‐1/ZIF‐90 (AO/ZIF) MMM exhibits an exceptional CO2 separation performance with the CO2/N2 and CO2/CH4 selectivity of 42.08 and 71.25, respectively, and a CO2 gas permeability of 1719.1 Barrer. In addition, in situ preparation of ZIF‐8 and ZIF‐67 nanofillers among the AOPIM‐1 matrix further confirms the versatility of the proposed “solvent‐evaporation‐induced‐confinement” strategy. The proposed strategy presents a versatile approach to achieve tunable growth of MOF nanofillers for the preparation of high‐performance PIMs‐based MMMs for carbon capture.

AbstractMetal–organic framework (MOF) catalysts promise selective hydrogenation of C═O bonds, a process that is thermodynamically unfavorable because of the presence of C─O, C═C, and C─C bonds within furan rings. However, the reactivity and stability of MOF are often impeded in catalytic reactions by structural collapse or phase transition stemming from commonly employed strategies such as defect engineering. The present work investigates a novel strategy for designing highly active Co₁Ni₁@UiO‐66‐NH₂ catalysts by embedding Co₁Ni₁ within the UiO‐66‐NH₂ framework. This approach facilitates efficient charge transfer between the reactants and the catalysts, thereby preserving both reactivity and structural integrity. The turnover frequency of Co1Ni1@UiO‐66‐NH2 is 430 h⁻¹, in contrast to 18 h⁻¹ of UiO‐66‐NH2, demonstrating that the transfer hydrogenation activity of Co1Ni1@UiO‐66‐NH2 is 24 times greater than that of UiO‐66‐NH2. More importantly, the reaction rate achieves 7.27 mol g⁻¹ h⁻¹, with a furfuryl alcohol (FOL) yield of 100%, and the Co₁Ni₁@UiO‐66‐NH₂ catalyst retains its excellent catalytic activity even after eight cycles of applications. Density functional theory calculations indicate that, in comparison to UiO‐66‐NH₂, Co‐ and Ni@UiO‐66‐NH₂, Co₁Ni₁@UiO‐66‐NH₂ exhibits relatively strong interactions and significant charge exchanges between reactants and catalysts. These interactions not only facilitate the dehydrogenation of isopropanol but also enhance the hydrogenation of furfural. Furthermore, the density of states reveals a greater number of states near the Fermi level in Co1Ni1@UiO‐66‐NH2 compared to Co‐ and Ni@UiO‐66‐NH2, and thereby facilitates the substantial charge exchanges and efficient catalytic performance of Co1Ni1@UiO‐66‐NH2.

AbstractThe decreased regeneration potential of aging nucleus pulposus resident progenitor cells (NPPCs) fails to resist intervertebral disc degeneration (IVDD), and strategies to remodel the regeneration capacity of senescent NPPC are urgently needed. A decrease in Klotho gene expression in NPPCs of both old mice and humans exacerbates the impaired regenerative functionality of NPPC. Here, an NPPC‐targeted lipid thymine nanoparticle (NT‐LNP) is reported for the in situ manipulation of the regenerative repair potential of NPPCs, restoration of degenerated nucleus pulposus tissue, and mitigation of IVDD. Specifically, the results showed that the in‐house customized lipid nanoparticles efficiently introduced Klotho circular ribonucleic acid (circRNA) into NPPCs to engender a renascent phenotype and tuned the balance of extracellular matrix synthesis/catabolism in vitro and in vivo. Moreover, an intradiscal injectable hydrogel system that scavenges chemokines (MCP1 and IL8) in tandem with NPPCs rejuvenated NT‐LNPs in the IVD, modulating the inflammatory environment and synergistically promoting the regeneration of degenerated intervertebral discs. In summary, the findings establish that NPPCs can be re‐engineered to be youthful and pluripotent to maintain homeostasis and rejuvenation, thereby providing a reversible treatment strategy for IVDD with broad application in other senescence‐related diseases.
