Efficient hash function–based duplication detection algorithm for data Deduplication deduction and reduction

J.K. Periasamy, B. Latha

Concurrency and Computation: Practice and Experience > 33 > 3 > n/a - n/a

Data Deduplication is the foremost technique used for data compression by removing redundant data. It is broadly utilized for cloud storage server, which reduces the un‐utilized memory space and optimized bandwidth. The confidentiality of sensitive information maintains during Deduplication detection. The Efficient Hash Function–based Duplication Detection (EHFDD) algorithm is proposed to encrypt...

Enhanced polynomial kernel (EPK)–based support vector machine (SVM) (EPK‐SVM) classification technique for speech recognition in hearing‐impaired listeners

Pavithra S, Janakiraman S

Concurrency and Computation: Practice and Experience > 33 > 3 > n/a - n/a

Automatic speech recognition of Tamil Language with Hearing‐Impaired becomes difficult task in recent decades. In order to deal with the challenges with speech perception in hostile listening situations, Noise Reduction (NR) algorithms have been developed with the aim of improving the speech intelligibility (SI), speech quality, and ease of listening. Even though the noises are removed, extraction...

Climatic structures and intensities of the last two glacials documented by terrestrial molluscs from Chinese loess sequences

Dan Zhang, Nai‐Qin Wu, Feng‐Jiang Li, Denis‐Didier Rousseau, more

Boreas > 50 > 1 > 308 - 320

Knowledge of the structures and intensities of past glaciations is crucial for understanding Quaternary palaeoclimatic evolution. Terrestrial molluscs are a reliable proxy of past environmental conditions and can provide specific climatic insights into glacials. Here we compare the climatic evolution of the last two glacials, based on mollusc fossils from the L2 and L1 loess units (equivalent to Marine...

Limnological response to the Laacher See eruption (LSE) in an annually laminated Allerød sediment sequence from the Nahe palaeolake, northern Germany

Stefan Dreibrodt, Sascha Krüger, Jan Weber, Ingo Feeser

Boreas > 50 > 1 > 167 - 183

This paper presents evidence for a limnological response to the Laacher See eruption (LSE) as detected in lake sediments from Nahe, northern Germany. The sediment section of the Allerød period dating to between 13 422 and 12 708 cal. a BP is preserved in annual laminations. Within this section, the LSE was identified as a cryptotephra layer (12 944±44 cal. a BP). Microfacies analysis, continuous high‐resolution...

Loess deposits in the Tajik Basin, Central Asia: chronology, provenance and palaeoclimatic implications since the Last Glacial

Shengchen Tian, Jimin Sun, Zhiliang Zhang, Sherzod Abdulov, more

Boreas > 50 > 1 > 147 - 166

The thick loess deposits in Tajikistan are important archives for palaeoclimatic reconstruction in Central Asia during the Quaternary. To date however, adequate high‐resolution studies of chronology and climatic evolution of the Tajik loess have still not been carried out. In this paper, chronology, dust provenance, and palaeoclimatic significance of a loess section in the centre of the Tajik Basin...

Three‐dimensional finite element analysis of the dural folds and the human skull under head acceleration

Andreas Lipphaus, Ulrich Witzel

The Anatomical Record > 304 > 2 > 384 - 392

Bone and collagen fiber architecture adapt to external mechanical loads. In humans, due to the low insertion of the temporal muscle, mastication does not lead to a physiological loading of the calvaria. Forces applied to the skull by the dural folds can lead to compressive stresses in the calvaria. To investigate the relationship between mechanical loads and form in the skull and its membranes, in...

A Metal‐ and Azide‐free Oxidative Coupling Reaction for the Synthesis of [1,2,3]Triazolo[1,5‐a]quinolines and their Application to Construct C−C and C‐P Bonds, 2‐Cyclopropylquinolines and Imidazo[1,5‐a]quinolines

Zhi‐Hao Shang, Zhen‐Xiao Zhang, Wei‐Zhao Weng, Yu‐Fei Wang, more

Advanced Synthesis & Catalysis > 363 > 2 > 490 - 496

An iodine‐promoted one‐pot cascade oxidative annulation reaction has been developed for the synthesis of [1,2,3]triazolo[1,5‐a]quinolines from methyl azaarenes and N‐tosylhydrazines. The reaction has a broad substrate scope and can be easily scaled up to gram‐scale. 1,2,3‐Triazoles are an important skeletal structure for the construction of C−C and C−P bonds, 2‐cyclopropylquinolines and imidazo[1,5‐a]quinolines,...

Gold‐Catalyzed Bicyclic and [3+2]‐Annulations of Internal Propargyl Alcohols with Nitrones and Imines To Yield to Two Distinct Heterocycles

Sayaji Arjun More, Tzu‐Hsuan Chao, Mu‐Jeng Cheng, Rai‐Shung Liu

Advanced Synthesis & Catalysis > 363 > 2 > 525 - 531

A gold‐catalyzed synthesis of 1,3‐dihydrooxazolo[3,4‐a]indoles from 1‐oxo‐3‐yn‐4‐ols and nitrones is described; this new bicyclic annulation presents the first examples that internal alkynes can react with nitrones to undergo an oxoarylation route. DFT calculations indicate a [3,3]‐sigmatropic shift of initial alkenylgold intermediates to elude the intermediacy of gold carbenes. We also developed...

Regioselective and Chemodivergent Synthesis of Azulenolactones and Azulenolactams from Rhodium(III)‐Catalyzed Reactions of Azulenecarboxamides with Sulfoxonium Ylides

Seung Cheol Lee, Jeong‐Yu Son, Jin Young Kim, Hyeonsik Eom, more

Advanced Synthesis & Catalysis > 363 > 2 > 512 - 524

A regioselective and chemodivergent synthetic approach for azulenolactones and azulenolactams as a new scaffold was demonstrated through Rh(III)‐catalyzed reaction of N‐methoxyazulene‐1‐carboxamides with sulfoxonium ylides. Sulfoxonium ylides that act as a precursor of secondary carbene was described, leading to the selective formation of azulenolactones and azulenolactams bearing two substituents...

Electrochemical Regioselective Phosphorylation of Nitrogen‐Containing Heterocycles and Related Derivatives

Yong Deng, Shiqi You, Mengyao Ruan, Ying Wang, more

Advanced Synthesis & Catalysis > 363 > 2 > 464 - 469

The site‐selective functionalization of biologically important nitrogen‐containing heterocycles and related derivatives remains a challenging and important task. We report herein on the direct regiodivergent N1/C2 phosphorylation of free indole derivatives. Cyclic voltammograms and EPR data indicate that by utilizing different electrolyte‐mediated anodic oxidation to generate different active indole...

Ruthenium Catalyzed Regioselective β‐C(sp³)−H Functionalization of N‐Alkyl‐N′‐p–nitrophenyl Substituted Piperazines using Aldehydes as Alkylating Agents

V. Murugesh, Apurba Ranjan Sahoo, Mathieu Achard, Gangavaram V. M. Sharma, more

Advanced Synthesis & Catalysis > 363 > 2 > 453 - 458

Herein, we disclose a ruthenium‐catalyzed regioselective β‐C(sp³)−H bond functionalization on the piperazine core using aldehydes as alkylating agents. The present transformation appears to go through the dehydrogenation of the piperazine to propagate to enamine in situ, followed by nucleophilic addition to the aldehyde and hydrogenation to result in the regioselective β‐C(sp³)−H alkylation. A variety...

Synthesis of Hydrobenzoimidazoles from para‐Quinamines and 1,3,5‐Triazinanes via a Formal [3+2] Annulation Reaction

Xinping Zhang, Bin Cheng, Hui Li, Yixuan He, more

Advanced Synthesis & Catalysis > 363 > 2 > 565 - 569

The synthesis of hydrobenzoimidazoles from para‐quinamines and 1,3,5‐triazinanes was achieved via a formal [3+2] annulation reaction in the presence of In(OTf)₃ as the catalyst. Further studies demonstrated that the synthesis of hydrobenzooxazoles could also be accomplished via the same strategy from para‐quinols and 1,3,5‐triazinanes.
