The reaction of CoBr2, KNCSe and 2-methyl­pyridine N-oxide (C6H7NO) in ethanol leads to the formation of crystals of [Co(NCSe)2(C6H7NO)3] (1) and [Co(NCSe)2(C6H7NO)4] (2) from the same reaction mixture. The asymmetric unit of 1 is built up of one CoII cation, two NCSe− iso­seleno­cyanate anions and three 2-methyl­pyridine N-oxide coligands, with all atoms located on general positions. The asymmetric unit of 2 consists of two cobalt cations, four iso­seleno­canate anions and eight 2-methyl­pyridine N-oxide coligands in general positions, because two crystallographically independent complexes are present. In compound 1, the CoII cations are fivefold coordinated to two terminally N-bonded anionic ligands and three 2-methyl­pyridine N-oxide coligands within a slightly distorted trigonal–bipyramidal coordination, forming discrete complexes with the O atoms occupying the equatorial sites. In compound 2, each of the two complexes is coordinated to two terminally N-bonded iso­seleno­cyanate anions and four 2-methyl­pyridine N-oxide coligands within a slightly distorted cis-CoN2O4 octa­hedral coordination geometry. In the crystal structures of 1 and 2, the complexes are linked by weak C—H⋯Se and C—H⋯O contacts. Powder X-ray diffraction reveals that neither of the two compounds were obtained as a pure crystalline phase.

The pyrazolo­pyrimidine moiety in the title mol­ecule, C13H12N4S, is planar with the methyl­sulfanyl substituent lying essentially in the same plane. The benzyl group is rotated well out of this plane by 73.64 (6)°, giving the mol­ecule an approximate L shape. In the crystal, C—H⋯π(ring) inter­actions and C—H⋯S hydrogen bonds form tubes extending along the a axis. Furthermore, there are π–π inter­actions between parallel phenyl rings with centroid-to-centroid distances of 3.8418 (12) Å. A Hirshfeld surface analysis of the crystal structure indicates that the most important contributions to the crystal packing are from H⋯H (47.0%), H⋯N/N⋯H (17.6%) and H⋯C/C⋯H (17.0%) inter­actions. The volume of the crystal voids and the percentage of free space were calculated to be 76.45 Å3 and 6.39%, showing that there is no large cavity in the crystal packing. Evaluation of the electrostatic, dispersion and total energy frameworks indicate that the cohesion of the crystal structure is dominated by the dispersion energy contributions.

The title mol­ecule, C25H23BrN2O2, adopts a cup shaped conformation with the distinctly ruffled imidazolidine ring as the base. In the crystal, weak C—H⋯O hydrogen bonds and C—H⋯π(ring) inter­actions form helical chains of mol­ecules extending along the b-axis direction that are linked by additional weak C—H⋯π(ring) inter­actions across inversion centres. The Hirshfeld surface analysis of the crystal structure indicates that the most important contributions for the crystal packing are from H⋯H (51.0%), C⋯H/H⋯C (21.3%), Br⋯H/H⋯Br (12.8%) and O⋯H/H⋯O (12.4%) inter­actions. The volume of the crystal voids and the percentage of free space were calculated to be 251.24 Å3 and 11.71%, respectively, showing that there is no large cavity in the crystal packing. Evaluation of the electrostatic, dispersion and total energy frameworks indicate that the stabilization is dominated by the dispersion energy.

The structures of the title compounds 2-hy­droxy-N'-methyl­acetohydrazide, 1, and 2-hy­droxy-N-methyl­acetohydrazide, 2, both C3H8N2O2, as regioisomers differ in the position of the methyl group relative to the N atoms in 2-hy­droxy-acetohydrazide. In the structure of 1, the 2-hy­droxy-acetohydrazide core [OH—C—C(=O)—NH—NH] is almost planar and the methyl group is rotated relative to this plane. As opposed to 1, in the structure of 2 all non-hydrogen atoms lie in the same plane. The hydroxyl and carbonyl groups in structures 1 and 2 are in trans and cis positions, respectively. The methyl amino group and carbonyl group are in the cis position relative to the C—N bond in structure 1, while the amino group and carbonyl group are in the trans position relative to the C—N bond in stucture 2. In the crystal, mol­ecules of 1 are linked by N—H⋯O and O—H⋯N inter­molecular hydrogen bonds, forming layers parallel to the ab crystallographic plane. A Hirshfeld surface analysis showed that the H⋯H contacts dominate the crystal packing with a contribution of 55.3%. The contribution of the H⋯O/O⋯H inter­action is somewhat smaller, amounting to 30.8%. In the crystal, as a result of the inter­molecular O—H⋯O hydrogen bonds, mol­ecules of 2 form dimers, which are linked by N—H⋯O hydrogen bonds and a three-dimensional supra­molecular network The major contributors to the Hirshfeld surface are H⋯H (58.5%) and H⋯O/O⋯H contacts (31.7%).

Hendrickson & Lattman [Acta Cryst. (1970), B26, 136–143] introduced a method for representing crystallographic phase probabilities defined on the unit circle. Their approach could model the bimodal phase probability distributions that can result from experimental phase determination procedures. It also provided simple and highly effective means to combine independent sources of phase information. The present work discusses the equivalence of the Hendrickson–Lattman distribution and the generalized von Mises distribution of order two, which has been studied in the statistical literature. Recognizing this connection allows the Hendrickson–Lattman distribution to be expressed in an alternative form which is easier to interpret, as it involves the location and concentration parameters of the component von Mises distributions. It also allows clarification of the conditions for bimodality and access to a simplified analytical method for evaluating the trigonometric moments of the distribution, the first of which is required for computing the best Fourier synthesis in the presence of phase, but not amplitude, uncertainty.

NdGa hydride and deuteride phases were prepared from high-quality NdGa samples and their structures characterized by powder and single-crystal X-ray diffraction and neutron powder diffraction. NdGa with the orthorhombic CrB-type structure absorbs hydrogen at hydrogen pressures ≤ 1 bar until reaching the composition NdGaH(D)1.1, which maintains a CrB-type structure. At elevated hydrogen pressure additional hydrogen is absorbed and the maximum composition recovered under standard temperature and pressure conditions is NdGaH(D)1.6 with the Cmcm LaGaH1.66-type structure. This structure is a threefold superstructure with respect to the CrB-type structure. The hydrogen atoms are ordered and distributed on three fully occupied Wyckoff positions corresponding to tetrahedral (4c, 8g) and trigonal–bipyramidal (8g) voids in the parent structure. The threefold superstructure is maintained in the H-deficient phases NaGaH(D)x until 1.6 ≥ x ≥ 1.2. At lower H concentrations, coinciding with the composition of the hydride obtained from hydrogenation at atmospheric pressure, the unit cell of the CrB-type structure is resumed. This phase can also display H deficiency, NdGaH(D)y (1.1 ≥ y ≥ 0.9), with H(D) exclusively situated in partially empty tetrahedral voids. The phase boundary between the threefold superstructure (LaGaH1.66 type) and the onefold structure (NdGaH1.1 type) is estimated on the basis of phase–composition isotherms and neutron powder diffraction to be x = 1.15.

X-ray reflectometry (XRR) is a powerful tool for probing the structural characteristics of nanoscale films and layered structures, which is an important field of nanotechnology and is often used in semiconductor and optics manufacturing. This study introduces a novel approach for conducting quantitative high-resolution millisecond monochromatic XRR measurements. This is an order of magnitude faster than in previously published work. Quick XRR (qXRR) enables real time and in situ monitoring of nanoscale processes such as thin film formation during spin coating. A record qXRR acquisition time of 1.4 ms is demonstrated for a static gold thin film on a silicon sample. As a second example of this novel approach, dynamic in situ measurements are performed during PMMA spin coating onto silicon wafers and fast fitting of XRR curves using machine learning is demonstrated. This investigation primarily focuses on the evolution of film structure and surface morphology, resolving for the first time with qXRR the initial film thinning via mass transport and also shedding light on later thinning via solvent evaporation. This innovative millisecond qXRR technique is of significance for in situ studies of thin film deposition. It addresses the challenge of following intrinsically fast processes, such as thin film growth of high deposition rate or spin coating. Beyond thin film growth processes, millisecond XRR has implications for resolving fast structural changes such as photostriction or diffusion processes.

For a reliable characterization of materials and systems featuring multiple structural levels, a broad length scale from a few ångström to hundreds of nanometres must be analyzed and an extended Q range must be covered in X-ray and neutron scattering experiments. For certain samples or effects, it is advantageous to perform such characterization with a single instrument. Neutrons offer the unique advantage of contrast variation and matching by D-labeling, which is of great value in the characterization of natural or synthetic polymers. Some time-of-flight small-angle neutron scattering (TOF-SANS) instruments at neutron spallation sources can cover an extended Q range by using a broad wavelength band and a multitude of detectors. The detectors are arranged to cover a wide range of scattering angles with a resolution that allows both large-scale morphology and crystalline structure to be resolved simultaneously. However, for such analyses, the SANS instruments at steady-state sources operating in conventional monochromatic pinhole mode rely on additional wide-angle neutron scattering (WANS) detectors. The resolution must be tuned via a system of choppers and a TOF data acquisition option to reliably measure the atomic to mesoscale structures. The KWS-2 SANS diffractometer at Jülich Centre for Neutron Science allows the exploration of a wide Q range using conventional pinhole and lens focusing modes and an adjustable resolution Δλ/λ between 2 and 20%. This is achieved through the use of a versatile mechanical velocity selector combined with a variable slit opening and rotation frequency chopper. The installation of WANS detectors planned on the instrument required a detailed analysis of the quality of the data measured over a wide angular range with variable resolution. This article presents an assessment of the WANS performance by comparison with a McStas [Willendrup, Farhi & Lefmann (2004). Physica B, 350, E735–E737] simulation of ideal experimental conditions at the instrument.

Geological formations provide a promising environment for the long-term and short-term storage of gases, including carbon dioxide, hydrogen and hydro­carbons, controlled by the rock-specific small-scale pore structure. This study investigates the nanoscale structure and gas uptake in a highly porous silica aerogel (a synthetic proxy for natural rocks) using transmission electron microscopy, X-ray diffraction, and small-angle and ultra-small-angle neutron scattering with a tracer of deuterated methane (CD4) at pressures up to 1000 bar. The results show that the adsorption of CD4 in the porous silica matrix is scale dependent. The pore space of the silica aerogel is fully accessible to the invading gas, which quickly equilibrates with the external pressure and shows no condensation on the sub-nanometre scale. In the 2.5–50 nm pore size region a classical two-phase adsorption behaviour is observed. The structure of the aerogel returns to its original state after the CD4 pressure has been released.

The first Federation of European Biochemical Societies Advanced Course on macromolecular crystallization was launched in the Czech Republic in October 2004. Over the past two decades, the course has developed into a distinguished event, attracting students, early career postdoctoral researchers and lecturers. The course topics include protein purification, characterization and crystallization, covering the latest advances in the field of structural biology. The many hands-on practical exercises enable a close interaction between students and teachers and offer the opportunity for students to crystallize their own proteins. The course has a broad and lasting impact on the scientific community as participants return to their home laboratories and act as nuclei by communicating and implementing their newly acquired knowledge and skills.

This article presents a web-based framework to build a database without in-depth programming knowledge given a set of CIF dictionaries and a collection of CIFs. The framework consists of two main elements: the public site that displays the information contained in the CIFs in an ordered manner, and the restricted administrative site which defines how that information is stored, processed and, eventually, displayed. Thus, the web application allows users to easily explore, filter and access the data, download the original CIFs, and visualize the structures via JSmol. The modulated structures open database B-IncStrDB, the official International Union of Crystallography repository for this type of material and available through the Bilbao Crystallographic Server, has been re-implemented following the proposed framework.

Volatus Aerospace Inc. (TSXV:FLT; OTCQX:TAKOF:ABBA.F) secured CA$2.8 million (CA$2.8M) through a private placement after having recently completed a financing package for CA$15M, reported Ventum Capital Markets analyst Rob Goff in a Nov. 6 research note. Volatus provides aerial intelligence solutions using drones and other aircraft systems, including inspections, surveillance, design, and sales.

"We believe the two financing rounds should be positively rewarded by investors for the financial flexibility they bring to Volatus, while the commitment of the two debt partners represents a strong validation," Goff wrote.

192% Return Implied

Goff reiterated Ventum's target price on the Canadian aircraft solutions provider of CA$0.38 per share. In comparison, it was trading at the time of the report at CA$0.13 per share. From this price, the return to target is 192%.

Volatus is a Buy.

Plans for Using the Funds

Goff discussed the private placement and Volatus' intended uses of it. For the offering, a total of 19,766,000 units was sold at CA$0.14 apiece. Each unit consists of one common Volatus voting share and one common Volatus voting share purchase warrant. With each warrant, the holder may purchase one Volatus common share for CA$0.20 per warrant share during the 24 months after the close of the raise.

"We believe the equity and debt financing will allow Volatus to invest in working capital to support higher equipment sales," an advantage its smaller peers do not have, Goff wrote.

The company expects to fund about CA$9–12M in unmet equipment sales demand, so Goff forecasts it will designate CA$3–4M to this purpose, to purchase working capital. Other uses of the proceeds are for research and development, capital expenditures and inventory.

Goff reported that Volatus wants to leverage every incremental CA$1M of invested working capital into about CA$3–4M of incremental equipment sales annually, aiming for gross profit margins of about 25% and modest incremental operating costs.

Volatus plans to use proceeds from the debt raise to back pay the outstanding CA$6M senior loan it has with a major Canadian bank. The company also intends to open a new secured line of credit to support anticipated growth. Current debt related to its fleet financing is about CA$5M.

Opportunities for Growth

With more balance sheet flexibility, Goff wrote, Volatus may pursue longer-term contracts with utilities and pipelines for inspection services using unmanned and manned fleets. This would position the company to become a leader in this specific market.

Volatus can monetize its portfolio of drones and landing stations. The U.S.' initiatives and intention to reduce use of Chinese-manufactured products could help drive this expansion. The company has third-party manufacturing capabilities to significantly boost its equipment sales.

"We anticipate that Volatus will leverage its unique software, network, and equipment capabilities, stewarded by an experienced and commercially focused leadership team," Goff wrote.

Future Financial Expectations

Goff discussed forecasts for merger synergies, EBITDA, and revenue. As for initial efficiencies achieved from Volatus' merger with Drone Delivery Canada, they should be seen in Volatus' Q4/24 and Q1/25 financial results, Goff wrote. Already, the company has exceeded CA$2.6M in cost synergies and expects to surpass CA$3M in the near term. By 2026, the company estimates revenue synergies will be about CA$5M-plus and will include initial traction gained from business-to-business cargo delivery.

Looking to 2025, Ventum expects Volatus to turn EBITDA break even in Q2/25 and produce CA$5.7M in positive EBITDA in 2025 versus Volatus' estimate of CA$10M-plus, Goff reported. Ventum estimates that Volatus will generate CA$60.3M in revenue in full-year 2025, less than Volatus' guidance of CA$70M+.

"We anticipate that Volatus will leverage its unique software, network, and equipment capabilities, stewarded by an experienced and commercially focused leadership team," wrote Goff.

The Los Angeles County Metropolitan Transportation Authority is pulling ads for the Fox television show "Red Band Society" from nearly 200 buses amid complaints they are racist and offensive to women.

The ads show the ensemble cast's members in front of a wall with graffiti describing their characters.

A denigrating word for a woman is used to describe the show's star, Octavia Spencer's character.

The Los Angeles Times reports transit officials began pulling the ads on Wednesday. They had been up for five weeks.

The Red Band Society also shared the ad on its Facebook page in August.

Dolly Varden Silver Corp. (DV:TSX.V; DOLLF:OTCQX) released results from five drill holes from its completed 2024 drilling program at its Kitsault Valley project in British Columbia's Golden Triangle.

In total, the program drilled 69 holes for 31,726 meters — 41 holes totaling more than 15,000 meters at the Dolly Varden area and 28 holes totaling more than 16,000 meters at Homestake Ridge.

Highlights of Monday's release include one hole from the Homestake Silver Deposit that found 12.23 grams per tonne gold (g/t Au) and 84 g/t silver (Ag) over 34.93 meters with high-grade breccia veins that included 166 g/t Au and 675 g/t Ag over 0.97 meters.

"The identification of a gold-rich, wide and high-grade area within the Homestake Silver Deposit is highly encouraging," said Chief Executive Officer Shawn Khunkhun. "Our geological team is encouraged by overlapping mineralizing phases of silver and gold-rich veins and breccias; the deposit remains open for expansion."

Technical Analyst Clive Maund, writing on Sunday, called Dolly Varden "one of the best pure silver companies around."

The stock's "breakout at end of last month/early this month was on big volume means it was genuine," Maund wrote.

The stock is at a "classic buy spot, although we should remain aware that it could zigzag a little lower over the short-term, but that said it looks like a strong buy here."

Highlights From Results

Highlights from the Homestake Silver Deposit include:

• Hole HR24-432: Mineralized envelope including veins: 8.85 g/t Au and 5 g/t Ag over 48.23 meters, including an internal zone of stronger breccia vein intervals grading 29.24 g/t Au and 16 g/t Ag over 13.94 meters, including one breccia vein grading 701 g/t Au and 184 g/t Ag over 0.54 meters.
• Hole HR24-435: Mineralized envelope including veins: 4.64 g/t Au and 38 g/t Ag over 100.80 meters, including an internal interval of stronger breccia vein mineralization grading 12.23 g/t Au and 84 g/t Ag over 34.93 meters. High-grade breccia veins include 166 g/t Au and 675 g/t Ag over 0.97 meters.
• Hole HR24-442: Vein breccia zone: 4.58 g/t Au over 9.95 meters, including 14.96 g/t Au over 1.69 meters.

"Results from the five holes in this release suggest that the plunge of mineralization at Homestake Silver has a similar orientation as the Homestake Main Deposit, located 300 meters to the northwest," the company said in a release. "The average grades within these core areas are higher, on a precious metal silver equivalent basis, than the average grade of the silver deposits at the Dolly Varden property further south, due to the increased gold content at the Homestake Ridge Deposits."

Technical Analyst Clive Maund, writing on Sunday, called Dolly Varden "one of the best pure silver companies around."

Drill holes HR24-442 and HR24-445 are step-outs and encountered the mineralized and altered structural corridor of Homestake Silver, the company said. Drill hole HR24-442 intersected a mineralized vein breccia stockwork zone grading 4.58 g/t Au over 9.95 meters, including individual breccias with stronger pyrite mineralization grading 14.96 g/t Au over 1.69 meters.

The Homestake Ridge deposits are interpreted as structurally controlled, multi-phase epithermal vein stockwork and vein breccia system hosted in Jurassic Hazelton volcanic rocks, Dolly Varden noted. Mineralization consists of pyrite plus galena and sphalerite with visible gold in a breccia matrix within a silica breccia vein system.

"The northwest orientation of the main Homestake structural trend appears to have numerous subparallel internal structures that are interpreted to form the controls for higher grade gold and silver shoots within a broader mineralized envelope at the Homestake Silver deposit," the company said. "The main structural corridor dips steeply to the northeast at Homestake Main and rolls to vertical or steeply southwest at Homestake Silver."

Analyst's Response: 'Boom'

Jeff Valks, Senior Analyst for The Gold Advisor newsletter, reacted to the results with the word "BOOM."

"Dolly Varden Silver reports more high-grade drill results from its 2024 exploration program at the Homestake Silver Deposit in British Columbia's Golden Triangle," he wrote on Monday. "Results from five drill holes have confirmed significant gold and silver mineralization in an area targeted within the plunge of a previously undrilled high-grade zone, signaling potential expansion opportunities."

Jeff Valks, Senior Analyst for The Gold Advisor newsletter, reacted to the results with the word "BOOM."

We look forward to the remaining results." Vaks wrote. "In the meantime, the stock is flat as I write but is up over 35% year-to-date. It's not too late to buy, it's down from its recent spike, and as (editor) Jeff (Clark) has said, this is a core holding for the silver bull market. Use a stink bid if you're looking for shares. Both Jeff and I hold long positions."

Analyst Marcus Giannini of Haywood Capital Markets noted in a recent research note that Dolly Varden continues to "push the margins of known high-grade mineralization" at the project.

Gianini gave the stock a Buy rating with a CA$2.40 per share target price. "We continue to view Dolly's high-grade endowment as an increasingly attractive target for larger North American-focused precious metal producers," he noted.

The Catalyst: Analysts Point to Patience

While it has chased the record highs gold has been setting this year, silver recently broke through US$35 per ounce, reflecting a year-to-date gain of about 47%. It has since settled but held to the "crucial US$32.50 level," according to Christopher Lewis of FX Empire on Monday.

"Keep in mind that this is a market that is extraordinarily volatile and, of course, will continue to be noisy over the next couple of days as we get election results in the United States," Lewis wrote. "And of course, we also get the Federal Reserve interest rate decision on Thursday, both of which could cause chaos."

Lewis said he thinks the "least likely path is lower."

"I still favor an upside move, but I recognize that we are definitely in a little bit of a holding pattern," he wrote. "Having said that, if we do see momentum to the upside, then there's really not a whole lot here that could keep this market from trying to challenge the (US$)35 level again, obviously, a large round psychologically significant figure, but we'll just have to wait and see how that plays out."

The most conductive element in nature, silver is used to coat electrical contacts in computers, phones, cars, and appliances. It's also an important element in solar technology.

Mordor Intelligence noted that the white metal is expected to register a compound annual growth rate (CAGR) of more than 5% between 2024 and 2029.

Newsletter editor Brien Lundin encouraged investors not to get discouraged, as any price drop-off is temporary, he said. He expects the silver price to soar when the U.S. Federal Reserve doubles down on its efforts to get interest rates much lower, he wrote on Oct. 23. [OWNERSHIP_CHART-5439]

Based on silver's charts, Ron Struthers of Struthers Resource Stock Report also predicted a major run-up in the silver price.

"Back in April or early May, I highlighted the breakout from a cup and handle formation and [that] that would lead to a major upside move. This is now confirmed," he wrote on Oct. 23.

Ownership and Share Structure

According to the company's latest corporate presentation, 50% of its stock is held by institutional investors, including Fidelity Management & Research Company LLC, Sprott Asset Management LP, U.S. Global Investors Inc., and Delbrook.

About 41% is with strategic investors, including 17% with Fury Gold Mines, 14% with Hecla, and Eric Sprott owns 10% himself.

The rest, 9%, is with retail and high-net-worth investors.

The company has 301.16 million outstanding shares. Its market cap is CA$380.72 million, and its 52-week trading range is CA$0.62–1.46 per share.

National Science Foundation (NSF)-funded researchers from North Carolina State and Elon universities have developed a technique that allows them to remotely control the movement of soft robots, lock them into position for as long as needed and later reconfigure the robots into new shapes. The technique relies on light and magnetic fields. "By engineering the properties of the material, we can control the soft robot's movement remotely; we can get it to hold a given shape; we can then return the robot to its original shape or further modify its movement; and we can do this repeatedly. All of those things are valuable, in terms of this technology's utility in biomedical or aerospace applications," says Joe Tracy, a professor of materials science and engineering at NC State and corresponding author of a paper on the work. In experimental testing, the researchers demonstrated that the soft robots could be used to form "grabbers" for lifting and transporting objects. The soft robots could also be used as cantilevers or folded into "flowers" with petals that bend in different directions. "We are not limited to binary configurations, such as a grabber being either open or closed," says Jessica Liu, first author of the paper and a Ph.D. student at NC State. "We can control the light to ensure that a robot will hold its shape at any point."

H.C. Wainwright & Co. analysts Andrew S. Fein, Matthew Caufield, Dr. Andres Y. Maldonado, and Dr. Ananda Ghosh, in a research report published on October 23, 2024, maintained a Buy rating on DBV Technologies SA (DBVT:NASDAQ) while raising their price target to US$7.00 from US$5.00. The report follows DBV's announcement of regulatory clarity regarding the path forward for its Viaskin Peanut patch.

The analysts highlighted the significance of the FDA agreement, stating, "DBV Technologies has reached an agreement with the FDA regarding the regulatory pathway for the Viaskin Peanut patch in toddlers aged one to three, under the Accelerated Approval pathway."

Regarding the company's development timeline, the analysts noted, "The Biologics License Application (BLA) submission for Viaskin Peanut in this age group is expected to be supported by positive efficacy and safety data from DBV's completed EPITOPE Phase 3 study, as well as additional safety data from the upcoming six-month COMFORT Toddlers supplemental safety study, which is expected to begin in 2Q25."

The report emphasized the strength of DBV's regulatory position, stating, "The FDA has stated that DBV has already satisfied two of the three criteria: the product treats a serious condition, and the product candidate provides a meaningful advantage over available therapies."

The analysts also highlighted progress in Europe, noting, "The EMA confirmed that the successfully completed EPITOPE Phase 3 efficacy and safety trial in the one to three-year-old population, along with positive results from the VITESSE study in the four to seven-year-old population, and a new safety study using the modified circular patch in one to three-year-olds, could support an MAA for the one to seven-year-old indication with the modified patch."

The analysts' valuation methodology for DBV Technologies is based on a composite approach. They explained, "Our US$7 price target is based on an equally weighted composite of: (a) US$5.10/share, as a 20x multiple of taxed and diluted FY34 GAAP EPS of US$5.13 discounted back to FY24 at 35%; and (b) an NPV of US$8.52/share with a 13% discount rate and 1% growth rate."

The report included commercial projections, with the analysts stating, "We continue to model initial approval in 2027, with projected initial sales of US$17.5M, growing to US$1,182.8M by 2034."

The analysts also outlined several risk factors, including potential clinical study failures, regulatory approval challenges, and market size uncertainties.

In conclusion, H.C. Wainwright & Co.'s increased price target to US$7 reflects growing confidence in DBV Technologies' regulatory pathway for the Viaskin Peanut patch. The share price at the time of the report of US$0.70 represents a potential return of approximately 900% to the analysts' target price, highlighting the significant upside potential if the company successfully navigates the regulatory process and commercializes its product.

Healthcare artificial intelligence (AI) company Treatment.com AI Inc. (TRUE:CSE; TREIF:OTCMKTS; 939:FRA) announced that it has closed a non-brokered private placement for aggregate gross proceeds of CA$1.95 million.

A total of 2,138,766 special warrants of the company were offered at CA$0.75 per special warrant with proceeds of CA$1.6 million. The company also said 466,666 units of the company were offered at CA$0.75 per unit for proceeds of CA$349,999.50.

The company said it intends to use the proceeds for working capital purposes.

"We are very encouraged by the support from our investors with their overwhelming response to the financing and the subsequent over-subscription," Chief Executive Officer Dr. Essam Hamza said. "This money will help expedite our aggressive growth plans over the next year."

Technical Analyst Clive Maund noted on October 9* that the outlook for the company is "outstandingly bright" because it has "positioned itself to revolutionize the healthcare industry using AI and advanced machine learning technologies."

The company "is set to transform the current archaic system so that no longer do patients have to sit for hours in waiting rooms to see a doctor or doctors, and doctors and other healthcare professionals have to suffer a crushing burden of often unnecessary patient visits and tedious repetitive bureaucracy," he wrote. "Treatment AI's platform will take care of most of it."

Healthcare Professionals Worldwide Contribute to AI Engine

Treatment.com AI said it is a company utilizing AI and best clinical practices with a goal to positively improve the healthcare sector and impact current inefficiencies and challenges.

With the input of hundreds of healthcare professionals globally, Treatment.com AI said it has built a comprehensive, personalized healthcare AI engine called the Global Library of Medicine (GLM). With more than 10,000 expert medical reviews, the GLM is designed to provide tested clinical information and support to all healthcare professionals, as well as providing recommended tests (physical and lab), X-rays, and billing codes.

According to the company, the GLM will help healthcare professionals (doctors, nurses, and pharmacists) reduce administrative burdens, creating more time for face-to-face patient appointments.

"AI is set to expedite and streamline the healthcare industry, making it vastly more efficient for the benefit of both healthcare professionals and patients," Maund noted.

The Catalyst: A 'Profound Transformation' in the Industry

AI has an important role to play in the healthcare offerings of the future, a 2019 report from the National Center of Biomechanical Medicine listed in the National Library of Medicine said. "In the form of machine learning, it is the primary capability behind the development of precision medicine, widely agreed to be a sorely needed advance in care."

Healthcare organizations are increasingly turning to the technology to address both clinical and administrative challenges. The combination of generative AI, as noted by Appinventiv in September, and operational tools like those developed by Treatment.com AI are driving this transformation.

Generative AI is "catalyzing a profound transformation within the healthcare industry" by generating synthetic data, predicting patient outcomes, and optimizing treatment plans, all of which revolutionize clinical decision-making processes, Appinventiv reported. This aligns with Treatment.com AI's announced collaboration with SPRYT on September 17 whereby integrating SPRYT’s AI receptionist "Asa" with its GLM has the goal of enhancing patient access to healthcare while reducing administrative burdens.

A CBC report from September 16 said real-world applications of AI in healthcare are already showing promising results. Dr. Muhammad Mamdani, co-author of a study on the topic, expressed optimism about AI's ability to "complement clinicians' own judgment and lead to better outcomes for fragile patients."

According to a report by Markets and Markets, the global AI in healthcare market in total was valued at US$20.9 billion this year and will reach an estimated US$148.4 billion by 2029, a compound annual growth rate (CAGR) of 48.1%.

"The growth of AI in the healthcare market is driven by the generation of large and complex healthcare datasets, the pressing need to reduce healthcare costs, improving computing power and declining hardware costs, and the rising number of partnerships and collaborations among different domains in the healthcare sector, and growing need for improvised healthcare services due to imbalance between healthcare workforce and patients," the report said.

Analyst: A 'Genuine Breakout Soon' for Stock

Maund said its stock charts are also looking "very positive indeed" for the company.

Of particular note is the big upleg late in June and early in July on persistent heavy volume, which broke the price clear above the May high and drove volume indicators steeply higher," the analyst noted. [OWNERSHIP_CHART-10594]

"This is very bullish price/volume action, especially as the volume indicators have not just held up but have actually advanced as the price has reacted back in a normal manner from the early July high to arrive at a support level where it has stabilized above the 200-day moving average in readiness for renewed advance, so the correction looks like a large bull Pennant that, as it is now closing up, promises renewed advance soon," continued Maund, who said holders should stay long and rated the stock a Strong Buy that "is thought worth going overweight on."

"The June-July rally must be classed as a 'preliminary' breakout," he noted. "But that said, the exceptionally bullish price/volume action of recent months does promise a genuine breakout soon that looks set to lead to a sustained and substantial uptrend."

Ownership and Share Structure

According to Sedi.ca, insiders own approximately 8% of Treatment.com AI. Retail investors own the remaining 92%.

The company has 48.84 million outstanding common shares and has 41.3 million free float traded shares.

As of October 31, the market cap is approximately CA$31.75 million. Over the past 52 weeks, the company traded between CA$0.355 and CA$1.11 per share.
